Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree.
The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side).
I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping them back to their original state, but in an order that does not intersect other branch vectors.
The idea came to me as a particularly difficult tree needed to come down in my friends yard, and we spent hours planning it out. I've already gotten some interest from the tree-surgeon community, I just need to appify it.
Second rendition will treat the problem more as a physics one than a graph one, with some energy-minimisation methods for solving.
The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it.
You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.
Entirely offline & no usage of AI. Free in-browser version (using PGLite WASM), paid desktop version.
I’m working on Popgot (https://popgot.com), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials.
On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging peanut butter with BPA by checking every photograph of the plastic or avoiding palm oil by reading the nutrition facts) or brand lists (e.g., only showing WSAVA-compliant dog foods). Still reviewing results manually to catch bad extractions.
Started this to replace a spreadsheet I was keeping for bulk purchases. Slowly adding more automation like alerting on price drops or restocking when under a threshold.
I am about to begin a PhD in astronomy. Until last month I was working at Caltech for 3 years on code which calculates orbits of asteroids to high precision. This code is being used on several NASA telescopes now to predict when they will image known asteroids (NEO Surveyor, SphereX, maybe Roman eventually). I was allowed to open source it and I am planning on making it the basis of my PhD research:
It can predict the location of the entire catalog of known asteroids to generally within the uncertainty of our knowledge of the orbits. Its core is written in rust, with a python frontend.
Colibri—a self-hostable web application to manage your (and your family's) ebook library, intended as a companion to Calibre. I want it to be a friendly, simple, capable, opinionated app to review your books, add metadata to them, get them onto your reader, share them with family and (few) friends, create a public shelf for bragging, connect with Goodreads etc., and exchange comments and reviews on books.
This is explicitly not intended to ever be monetised, and I enjoy all the implications that has on the design. Colibri is as much a tool I personally want to use, as it is a study in small-audience user interfaces, and the quest to build the perfect book catalog schema.
I'm looking for fellow book-loving people to work on Colibri, to create the best personal digital library possible. If you're interested, feel free to reach out via email (in bio), or on GitHub.
I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and started working on My Sukari as a platform of free tools for diabetics.
I mostly get time to work on it on the weekends, so it's not yet ready for public use, but I've fully fleshed out one of the main features: Sugar Dashboard - A dashboard that visualises your Glucose data and helps you easier analyse it.
I'm really passionate about this and getting as much free, practical tools in the hands of patients (it honestly shouldn't be this hard to manage a disease)
So many cool technical projects here. But I am doing something completely different - masonry. Repairing walls in 3 rooms. It includes reinstalling dozens of falling off bricks, installing 30 or so power outlets, replacing old windows with bigger modern ones, fixing openings for the doors and plastering everything afterwards. On one hand it’s interesting, because it’s very different from the dayjob. But doing it by myself pays my newish car in cash immediately. However I wouldn’t do it for money somewhere else, it’s really really hard work.
Instead of masonry I would like to work on time of flight cameras. But the day has only 24 hours :-(
I am working on the sunflower plant density estimation problem. The goal is to be able to estimate the germination rate as early as possible. Farmers benefit from such information, because:
- there are lots of expenses still to be made (fertilizer, pesticide, salaries), which may not be worth it if germination is under certain threshold
- if detected early, there is still time to plant another grain or to fill up the missing plants (requires precision seeders and seeding maps)
- is a very good proxy for yield estimation (farmers often trade futures even before they have harvested)
For the purpose I have created a dataset (a collaboration between my employer and Sofia University) and published it in order to enable scientific collaboration with other interested parties. Still working on the dataset annotations.
Working on a browser extension to make it easier to find content on YouTube that fits your interests.
I watch a lot of YouTube videos and have found it very annoying that YouTube latches onto one or two topics that you've watched and only recommends that type of content over and over again. Even if you use their "Not Interested" tool, not a whole lot changes in your recommendations.
At the end of last year I launched Relevant - a crowdsourcing website where users can categorize the channels they watch into a defined hierarchy of categories ranging from broad topics like "Science" and "Gaming" to more specific ones like "Phone Reviews" or "Speedrunning".
Although I've had good feedback on the website, engagement has been relatively low and I think that's because it's a big ask to have someone navigate to the website to find the content. This year I decided that I'd bring the content to them by making a Chrome extension that lets users interact with Relevant directly from within YouTube.
It's still a work in progress but I'd love to get a first version out within a month or so to start spreading the idea and gathering feedback. If this is of any interest to the people here on HN then please let me know what you'd like to see most on your feeds.
I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+).
In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession
It's niche and boring, but I help immigrants pick German health insurance.
The existing information is mostly blogspam from non-experts who try to make a quick buck. They only recommend the two brands with an affiliate program.
I wrote a better guide with help from competing insurance experts. The information is clear and succinct without oversimplifying things. It addresses the specific needs of immigrants.
Then I turned the advice into an interactive recommendation tool. People get clear, specific advice in a few seconds.
The best advice is "don't choose yourself, talk to a broker". The problem is finding a honest one. It took me years to vet a good one. After testing him for a year, I have set up an affiliate partnership from scratch with him. The partnership incentivises honesty and neutrality, because he has a lot of skin in the game.
I'm super excited about it. I can't overstate how much of an improvement it will be. Readers get far better advice and easy access to an expert. The broker gets a steady stream of well-informed leads. I get a commission for my trouble. It's a win-win-win situation.
I'm almost finished with a project that has taken up quite a lot of my life for the past few years, a book on Estonia! After working for their government and returning to the U.S. I wanted to better understand how the country modernized so effectively after gaining their independence from the Soviet Union so I did a fair amount of research into the topic and many interviews which culminated in a book, Rebooting a Nation.
If you're interested in Estonia, e-government, building tech hubs, and the future of the nation state I'd love if you take a look (and let me know what you think). It's available on Kindle now but Oxford University Press will be shipping out physical copies May 15 and buying from a smaller press is always appreciated!
Been a freelance dev for years, now going on "sabbatical" (love that word) imminently. Just moved to reduced hours, still in the transition and unwinding phase.
Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things.
I hacked my old kindle and turned it into a eink dashboard for my daughter’s school! Now planning to enahace it a bit further and make it easy to customise.
Reverse typesetting: reflowing page layouts where you don't have knowledge of the typesetting structure, i.e. a scanned physical book or PDF paper. Naive rules-based heuristics based on the dimensions of bounding boxes and gaps. Point is to reflow things for resizing to eink readers. (Specifically the size that fits in my pocket which I carry around. User #1 is me). Building in Common Lisp and targeting an Emacs mode for interactive execution with manual feedback.
If you’ve used H3 or S2 it should be familiar, the major difference (apart from the fact it uses pentagons) is that the cell areas are practically uniform, whereas alternative systems have a variance of around 2 between the largest and smallest cells, making them less useful for aggregation. The site has many visual demos, e.g. https://a5geo.org/examples/area
PodSnacks (https://podsnacks.org) — Personalized AI summaries of top podcasts, delivered to your inbox.
I've been building PodSnacks because I found it overwhelming to keep up with podcasts across tech, business, and science. PodSnacks uses LLMs to summarize the most popular episodes from shows like Lex Fridman, Acquired, All-In, Invest Like the Best, and more.
You choose your favorite shows, and we email you short, high-signal summaries — no audio to skim through, no endless backlog guilt.
So far:
126K+ episode summaries generated
92K+ hours of podcasts processed
48–50% open rates
2,900+ early users
Still iterating and adding features like bundling by theme, language translations, and audio feeds.
If you're the kind of person who wants more inputs without more noise — would love for you to check it out.
I've recently re-watched John Carmack's 2004 Quakecon keynote (https://www.youtube.com/watch?time_continue=602&v=OOVUZZr655...), which happened during the Doom 3 launch. In that keynote, he mentions that he didn't see any differences between stencil and shadow maps. He mentions that he experimented a lot with both approaches, before settling for stencil shadows which were much faster.
I got curious about that statement, since shadow maps tend to look much different. I also knew that he left part of the experimental renderer in the GPLed code. So, I've decided to go on that rabbit hole of Doom 3 graphics, specifically Carmack's experimental renderer and ended up implementing his approach, as well as adding some poisson disc sampling and fixed the peter panning: https://github.com/klaussilveira/exp-dhewm3
I also spend a lot of time on archaic game engines. I like to call it software archeology.
I launched my web-based notepad calculator, https://numpad.io/, a few years ago.
Right now I'm working on a version 2 that has user accounts, multiple documents, markdown support, and document exports. Everything is local-first and it uses CRDTs to sync documents.
It looks like this: https://i.imgur.com/Plk1DQ4.png the calculator is mostly the same for now, with a few improvements. It's unstable right now, so I don't want to publicise the dev url, but if you'd like to become a beta tester email me at contact@numpad.io
I just put live a daily logic puzzle, Clues by Sam. I've been working on it for a while now, mainly on the level generator. It was tricky to generate levels that are solvable using logic (no guessing needed), and also fun to solve (no crazy long deduction chains, but also not just obvious things). I'm sure the implementation still has some quirks on some devices, so would love to hear if you encounter issues!
Creating stealth group in a huge Fortune 500 company with the blessing of my immediate boss but no other higher-ups. Trying to productize critical consulting tool sets in the utility industry so we can stop repeating ourselves for the 100th consulting engagement.
Yes, customer is a special snowflake but they still need 90% or whatever every other client in this industry needs.
Feeling increasingly like this is a fools errand.
Even though we've proved this out with tool sets strung together with duct tape and safety pins, and are therefore the most profitable group within our department, we still need to be 100% billable.
It's only because we're the most profitable group that we can pretend we're all billable while I work with two other people to bootstrap this crazy project
Edit: anyone hiring? Just found out my boss is quitting.
It tried out vibe coding this weekend. I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.
I hit an OpenSearch bug this week where you can't get any browser based requests to work. Its due to zstd becoming a standard part of Accept-Encoding and OpenSearch not correctly supporting it so I wanted to install a browser plugin that modified the browser HTTP request headers to my servers.
I don't know about everyone else but I love that browser plugins are possible but I hate having to find them. Its mostly due to never knowing if you can trust a plugin and even if you find one, you have to worry about it being bought out in the future. With vibe coding I was able to build a browser extension in 45 minutes that had more features than I originally planned for.
I spend more time documenting the experience than building which is wild. If you are interesting you can look at the README in https://github.com/mattheimer/vibe-headers
But I left the experience with two thoughts.
Even seasoned developers will be using vibe coding in the future.
I think in the near future the browser plugin market will partially collapse because eventually browsers will build extensions themselves on the fly using natural language.
A note taking app - I know, I know, been done a billion times. But really, no software I’ve found works the way I want it to, so I’m just trying to write my own, starting with a front-end agnostic core and a TUI.
If it strikes a chord with anyone, I’d love to collaborate! The concept is centered around organization bubbling up naturally from dumping info in with tags, and “typing” your tags so that when you go to a tag’s page, the layout is customized based on what it is - a project, person, etc. A project could have all relevant tasks and notes listed, whereas a person might have name, contact info, etc.
Working on a database compatibility tool. So your app works on SQL Server 2022 on-prem, but does it work on Azure SQL DB, AWS RDS, GCP CloudSQL, etc?
These cloud flavours have a compatible SQL dialect, but it's often details like missing features (CDC and Auditing on RDS are good examples) or differences in system objects that make it difficult to support your app on these platforms.
I capture all sql statements, run them through multiple SQL parsers to find all the system objects your app is using (tables, functions, stored procedures, etc). I then check them all against a catalog I have built of all system objects for every version of SQL Server on every platform.
I then give a report to see which platforms your app will work on, which ones it wont work on and which system objects are the problem.
Other database engines will be added once I get it working end to end (almost there).
I'm working on a new open source CAD program for 3d printing based on Signed Distance Functions.
Benefits of SDFs over the standard Boundary Representation (used in Freecad and similar) are that you can do "pattern" operations with domain repetition, which means making N copies of a feature is O(1), vs O(N^2), you can deform objects with domain deformation, which means if you have a closed-form representation of how you want to deform space you can basically directly apply that to your object, procedural surface texturing is easy, CSG operations are easy.
The big drawback is that it is hard to provide any workflow based around "selecting" faces, edges, or vertices, because you don't naturally have any representation for these things, they are emergent from the model's SDF.
I am solving the "selecting faces" problem by having the SDF propagate surface ids as well as distances. So the result of the evaluation is not just the distance to the nearest point on the surface, but the id of the specific surface that is nearest.
My next big frontier is reliably providing fillets and chamfers between arbitrary surfaces. I have a handful of partial solutions but nothing complete yet.
The most promising idea is one that o3 came up with called "masked clones", the idea is roughly to make a clone of the 2 surfaces you want to blend, mask them by intersecting with an object that is like a "pipe" along the intersection of the 2 surfaces, apply the blend within the pipe, and then add this "blend pipe" as another child of the lowest common ancestor of the 2 blended surfaces.
And after that I need to work on more standard CAD stuff like constraint solving in the 2d sketch editor.
https://undetectag.com I developed a device that turns an Airtag on and off at specific intervals.
Current Airtags are detectable right away and cannot be used to track stolen property.
That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location.
It’s not foolproof, as the timing has to be right, but still useful.
I am working on a super mario land re-implementation for game boy using C. It's made with the GBDK toolkit so the ROM can be run on a gameboy.
Currently the scrolling and background collision has been implemented, I am working on drawing the enemies... their is still a long way to go.
As for why I am doing this is nostalgia and fulfilled a childhood dream
repo at https://github.com/odrevet/marioland-gbdk/
I'm working on an escape room! Initially I was working on a software/hardware bundle that I was planning to market to other escape rooms but I think that is the wrong approach. So I am going to build a bunch of modular stuff in my garage and eventually start my own, its been an awesome project so far! I want a more dynamic and action oriented experience so it might not really be an escape room anymore but I don't know what to call it yet.
Escape rooms are honestly... almost always a let down but the concept has a lot of potential and there are some really neat ones that standout like this local one where you pilot an airship https://www.portlandescaperooms.com/steampunk-airship
Once I build the best escape room on the planet, I can consider selling the tools.
I'm hacking on Trailbound, a hiking and backpacking planning tool. The goal is combining a light version of the routing capability of Caltopo or GaiaGPS with more granular "leg" mapping based on how I learned to plan off trail trips and sharing functions that make it easy for my wife to know where I'm going to be, who I'm with, and who to contact if I'm not back in touch when I said I would be.
Its been a blast to build. At one point I was hosting my own ORS server but that's extremely silly to do when Mapbox has a very generous free tier. Learning about all of the open source tooling and open data available in the mapping world has been incredible.
The cost of the Hetzner box it runs on isn't much more than a Caltopo pro subscription with the added bonus of being much easier to share with non-hikers.
No marketing site, no onboarding, or any real UX attention paid to the app at this point, it is mostly Just For Me and will probably remain that way once I land a job again.
I'm starting to chip away at an iOS app so I can get offline access to maps and routes, but I'm not a Swift dev so the going is slow.
As a follow up to my relatively successful series in x86 Assembly of last year[1], I started making an OS that fits in a bootloader.
I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes.
It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor. It's a lot of fun!
I am working on an app for rhythm training for dancing.
The first step is beat detection in music - here is my code for generating videos with beat counting: https://github.com/zby/beat_counter (vibe coding warning). Beat detection seems to work OK, downbeats are a bit more tricky and I have found not good solutions for further structuring of music (for dancing they usually count to 8 - that is two 4 beat measures - or 6 - two 3 beat measures for Waltz for example, I am not sure about 2/2 measures and other). Seeing all the LLMs generating music I thought there should also be LLMs interpreting music - but so far I have found no such model the available algos seem to be from a previous decade.
My current plan is to test the counting with people with good rhythm sense and once I find a good algo for beat detection I'll proceed with writing the app.
In short, at the core of Tangled is what we call “knots”; they’re lightweight, headless servers that serve up your git repository, and the contents viewed and collaborated upon via the “app view” at tangled.sh. All social data (issues, comments, PRs, other repo metadata) is stored “on-proto”—in your AT Protocol PDS.
I've always been into MUDs since the mid-90s and every now and then I get this idea to write one from scratch (again) and I get pretty far and then I lose interest.
The new one is browser based.
The mud engine runs in a web worker and takes advantage of some of the modern web tricks to do stuff. For instance, data files (think: area files that don't change often) can be stored remotely and then cached with a service worker. This allows the MUD to run offline. But that's only fun if you're playing solo.
IO between the UI and worker is handled by message passing.
Multiplayer is handled by the MUD opening an outbound connection (probably websocket) to a connection collector host. Other players would then connect to that host and have their IO routed appropriately. The host can even be smarter: it could be a specialized Discord client, allowing users to play from there. Firebase may also be involved. I don't know.
The important bit is that this is still basically message passing, so the engine won't need to know the difference between the local user and a remote user.
The MUD database would be an IndexedDB. Probably. I haven't thought as much about that yet.
I am sure all of this is theoretically possible, at least.
Creating a modern development environment for win98. Currently I’m working on a git client. I have no patience for learning C. So backporting git is not an option. I also don’t want to use cygwin. So I’m using a server to expose git as http endpoints and coding a git client in php to use in msdos. I have Vim 7.3 and and gnu coreutils working in msdos already. So soon I will have a very nice dev environment. I want to create a one click installer which gives you xampp, vim and then all the tooling I’ve created. I’m also interested in creating SPA that works in IE5.5. But I’ll do that when my tooling is ready.
I'm building a platform for small-city business directories called TownWire: https://townwire.com
We launched our first location last week and have had a great response so far from business owners and residents alike: https://canandaigua.com
With the current tech climate of AI and big tech, things have gotten so impersonal for the majority of actual people. I'm betting on communities and the small businesses that serve those communities in the medium and long term.
I'm working on my second self-published technical book related to Elixir. The first one has been a surprising success, but since it was about learning to use Ecto on the basis of an old pedagogical toy database (and tiny dataset), the new book is about the development of a production-grade REST API with Elixir and Phoenix.
I find that many books out there are focused on documenting the "happy path" for rather small and simplistic applications without boundary conditions or business thinking behind them.
So, I thought (as with the first books) that it mix things up by also documenting the business context, the questions, decisions, and the decision-making process itself, as well as all the gotchas and "side-quests", rather than showing "here's how you do it" and then expecting the reader to suddenly make the jump from tutorial hell to actually software engineering.
Overall, it's enormously enjoyable, and I hope it goes as far as the first book, and possibly even farther.
A programming language for teenagers to learn to code by making multiplayer games. I've spent 3 years making the multiplayer completely automatic so you can just code it like a singleplayer game, then flick a switch and it just works. My hope is that teenagers will find it more engaging if they can play their games with their friends. A bit like a combination of Roblox and Scratch.
Currently trying to implement some region affinity so it doesn't just put everyone in the world in the same game. It's rollback netcode so the latency is very good even across continents, but it can't overcome the fact that the world is just too large.
The Goodreads of music. I'm a lifelong music nerd and have developed habits for finding and curating good music, both new and old. I'm codifying my habits and heuristics for discovering new music into an AI-powered social platform that can be used by anybody to widen their horizons in terms of music they listen to and to share their taste with others. https://waxnerd.com/adnan
> This weekend I’m working on mobile app that allows you to upload photos and it turns everything into a stitched anime (ghibli or not) with movements and eventually sound and script. Great to make mini animes from your day or travels or anything.
I vibe coded the above including everything: code, design, logos. Just did it solo. It has all error handling, video generation notifications (it takes a while) and credit system. I myself can't believe it's been done in a month with AI. It's already in closed beta in iOS and android app stores. Let me know if you want to try it out before public release.
My quoted comment above was 28 days ago. This is working on this part time and with a family.
I'm working on a human-like AI opponent for VR table tennis. It's something I really want myself, love playing table tennis in VR, but with online play you get the latency issues, people that have adopted a playing style which basically hacks the game physics or other aspects, or people who are just plain rude. Playing against the AI is much nicer, but it's not varied or realistic enough such that when you actually play against real people you are ill prepared.
A few released apps for now that are iOS/macOS, with some exciting more things in the pipeline.
If you’re a photographer who has frustrations with current mainstream photography software (whether capture/edit/publishing), I’d also love to hear from you - you can find me as Héliographe on (mastodon,bluesky,threads,x) or just email me at contact@heliographe.net :)
I built a garage workshop with a Shapeoko 5 Pro, X1C, soldering station, and learned CAD (ok just fusion). I have a lil drone in the air and I'm adding OpenHD for vtx, Rpi for on-edge compute (Jetson would be better but is expensive).
Haven't figured out FHSS or GNSS-denied nav yet (tbh I feel like fhss is gonna be harder). And SITL in a good sim remains to be conquered (ros on osx is a terrible experience). I'm also designing a battery pack that's modular, quick-swap, smart/telemetry.
I've shifted a lot of focus to networking (attending SOFweek in tampa) for the normal fundraising/team-building/customer discovery.
I'm also basically broke due to bootstrapping so I'm about to partner on some b2b ai saas consulting with a friend, today I got Suna up and running, pretty cool.
All the things that are important to me in one place: notes, habit tracker, brag doc, action log, todos, events, data collection, biolinks, and a lot more.
That certainly sounds a bit boring, and rightly reminds of great tools like Obsidian. However, there was always something missing from the tools, or the configuration was too complex. That's why I started to build one myself. It's a mix of pwa and local-first and Github sync. I don't want a tool that only works in the browser, I also need to be able to continue working seamlessly on my smartphone, and Github offers an endless history that I can view. Plus: I can clone the repo locally at any time.
I don't need a habit tracker service, a tool for notes or a brag doc service anymore. Everything is stored as files that I can access at any time. Other nice features are forms (like typeform) or an infinite number of biolinks.
I've been using it daily for a few months now and have already been able to replace a few services with it.
So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources.
4 years ago I made an install script that worked for Debian, Ubuntu and macOS. This made it easier to get going with them.
Over the last week or so I extended and polished that script to make it even easier and customizable, including adding Arch Linux support. The next step is to start installing and configuring GUI tools instead of only focusing on command line tools and environments.
I just used it the other day to set up a fresh work laptop in 5 minutes. Given the script is idempotent I run it all the time on my personal box.
Working on Uncloud [1] — open source tool for self-hosting containerised apps across multiple machines. You can combine cloud VMs and on-premises to create hybrid compute environments, e.g. for cost optimisation or data privacy.
While Kubernetes offers power at the cost of complexity, Uncloud focuses on simplicity for common deployment workflows.
Progress from this month:
- Enhanced Docker Compose support: You can now deploy your entire stack from standard Docker Compose files. This includes volumes, environment variables, resource limits, scaling and logging configuration.
- Volume management: Create and manage Docker volumes across your cluster with automatic scheduling based on volume location.
- Context management: CLI command to quickly switch between multiple clusters, e.g. homelab and production one
I'm particularly excited about the volume management system as it provides the cluster semantics to the good old Docker volumes. It uses a constraint-based scheduler that ensures services sharing volumes are properly co-located.
If you're seeking something between "just Docker" and full Kubernetes for deploying applications on your own infrastructure, I'd love to get your feedback on Uncloud.
Silly lisp-inspired language, but it turned into something different as I started asking myself more and more questions, and now it's more of a model for computation that tries to think about computers as different from looms (aka harward architecture).
One where self-modification is the norm, where there is no stack unless you make one, and where there's no difference between a program extending itself or the programmer doing it (unlike LISP macros, my language, and model, does not have a distinction, there's no macros).
I'm not doing this because I'm convinced it's a great idea, or because it's going to revolutionize computing, or because it will be a good language, model or beneficial in any particular way, I'm doing it because I think it's fun, neat and interesting to think about (and talk about).
My home-grown daily word game Omiword[1] (previously discussed on HN[2]) is nearing completion. Just a few last features and bug fixes to go, including a hint feature, access to archives, and a sharing feature.
I'm teaching myself category theory, I'll kick back off a local trail, keep notes on the birds I see and read and do the problems in my notebooks. I've got Basic Category Theory by Leinster, and How to Read and Do Proofs by Solow as my references, notebook, pen and a pair of Nikon binoculars.
A Prolog TUI library that sticks to relational/logical programming, is conceptually simple, complete, and performant.
Only requires some core ansi features that exist or are easily implemented in most Prologs.
Currently have stuff like nested scrollable areas, toggles, frames, buttons, layouts working.
Also, a visual programming language implemented as a PICO-8 script, where the "programming" is done fully in the sprite editor.
https://weexpire.org - An opensource tool for creating emergency notes that can be read by your trusted contacts only after your death or if you are seriously injured.
7 months ago, I was looking for a job and got frustrated with the current resume builders, so decided to build one exactly how I wanted a resume builder to be.
https://marketingagents.net - Marketing Automation for Founders who Suck at Marketing. Open Source and Self Hostable
Building this for myself mainly, but hoping others might find it useful. Still very early and building out the bear essentials, but then the hope is to keep reading marketing books and use that to improve the platform.
After three tough years in finance, I’ve decided to start a trip around the world, visiting the UK and the US, spending one month traveling through Japan, and then heading to South Korea.
There might be problems in life that can’t be solved with a three-month sabbatical trip around the world, but luckily, I don’t have any of them. :)
At the same time, I’m exploring ways to apply LLMs to video games and have built a small prototype of an LLM-based D&D system. Let’s see where this goes!
I recently started learning Rust so for my first non-trivial project I decided to build a system for real-time generative art driven by a DSL (defined with Pest) and interpreter that executes scripts for creating dynamic and interactive visuals. The goal is to make human-authored, interactive art more accessible than current methods like GLSL/ShaderToy but without going down the path of AI-generated content, although in theory there's nothing preventing users for using AI to generate scripts for this system. The project uses Nannou for graphics (via WebGL) and input handling (keyboard, mouse, MIDI, audio analysis). It will target WASM and I'll make it accessible as a web app where users can create and share their own projects. I'm also exploring community features to support collaboration and discovery. Still early days, but it’s been a fun way to get deep into Rust by building something creative and open-ended.
I've been building an intentionally annoying app against doomscrolling [1]. I've recently started with marketing, but oh boy is that out of my comfort zone!
I never thought that as an engineer I'd be doing TikToks. And here I am. It's fun to crack the algorithm little by little, but also frustrating because it's like a black box.
So far, I've discovered that going to the point works best. For example, I was sharing student tips and mentioning my app to improve focus. But conversion and engagement were terrible. Instead, I'm doing founder stories and tutorials, which get less views but more downloads. Plus, I can ask people in the comments for feedback on the app!
I'm happy to be doing something that devs overlook so much: marketing. Even if it's tough and slow. It's been an awesome learning experience.
Been building HelloCSV - an open source FlatFile alternative. I've been building this for work and the folks at work were cool enough to let me just build it in open source.
It basically runs 100% on your / your users browser, and I'm adding localstorage support so the user can refresh their page without losing their progress.
Love flatfile but it sends your data to remote servers, and we're a healthcare company, so we need to have full control over our data storage
My project is an ongoing one of self improvement. I've spent most of my adult life working on technical stuff, and it's taken a bit of a toll on me.
I quit working about ~20 months ago, started a low-carb time restricted eating regime, lost ~230 lbs, have been doing 15-25 hours of cardio a month for the past year, started going to therapy, got an ADHD diagnosis, read a bunch of classic literature (Middlemarch and The Count of Monte Cristo are my favs thus far), maintaining a 19 week streak of Latin language learning through the killer Legentibus iOS app, and I'm playing guitar every day (trying to nail the the major scale in three different fingerings across all 7 modal starting points).
I miss my old job working with Vitess and Kubernetes a lot (Hi Sam!) but eliminating all work stress has really allowed me to take control of my life.
I wanted to know what my kids were doing on the computer: homework or watching youtube shorts, so I built https://screenspy.app to monitor them. Now I’m working on turning it into a product.
I'm a member of the JSON Schema Technical Steering Committee, and been making a living consulting with companies making use of JSON Schema at large. Think data domains in the fintech industry, big OpenAPI specs, API Governance programs, etc. The tooling to support all of these use cases was terrible (non-compliant, half-baked, lack of advanced features, etc), and I've been trying to fix that. Some highlights include:
- An open-source JSON Schema CLI (https://github.com/sourcemeta/jsonschema) with lots of features for managing large schema ontologies (like a schema test runner, linter, etc)
- Blaze (https://github.com/sourcemeta/blaze), a high-performance JSON Schema C++ compiler/validator, proven to be in average at least 10x faster than others while retaining a 100% compliance score. For API Gateways and some high-throughput financial use cases
Right now I'm trying to consolidate a lot of the things I built into a "JSON Schema Registry" self-hosted micro-service that you can just provision your schemas to (from a git repo) and it will do all of the heavy lifting for you, including rich API access to do a lot of schema related operations. Still in alpha (and largely undocumented!), but working hard to transition some of the custom projects I did for various orgs to use this micro-service long term.
As a schema and open-source nerd, I'm working on my dream job :)
I was recently looking for a simple minimalist app launcher for iPhone that would respect my privacy and didn’t come with a stupid subscription plan, so instead I made my own!
https://apps.apple.com/us/app/applist/id6743515756
I'm continuously building and improving https://lectronz.com/, a marketplace for electronic enthusiasts and professionals that focuses on the open-hardware and DIY electronics communities.
We recently introduced "Threshold Pre-Orders," a pre-order mechanism that lets hardware creators gauge the market before committing to production/PCBA.
We have successfully tested this on four low-volume products already. See https://lectronz.com/u/lectronz/articles/introducing-thresho...
A midi sequencer, which does or is supposed to do what you expect.
In the process of adding stuff like euclydian sequences, and trying to figure out
how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory
behind it.
It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.
Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol).
I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, etc.).
After researching how the Toyota/Lexus infotainment systems work I found they are highly modular, and actually quite easy to produce custom modules for. The proprietary AVC-LAN protocol is well-understood, and actually makes it really easy to integrate with. The display are just NTSC composite, and touch events (in fact, all button presses, including steering wheel media controls) are emitted on the AVC-LAN bus.
An simple board with some interfacing logic, a DAC and an RPi nano should be all I need to allow good Bluetooth audio integration, and lossless audio via wired USB, both controllable from the steering wheel.
You could do all sorts of fun things with the display (such as displaying vehicle status from ODB, lap timer, G-force meter etc.). If I use a RPi compute module then running Android Auto should be quite feasible.
It's just a hobby project though, I'll probably open-source everything. Not planning on commercializing it.
I've been working on https://asterai.io -- a platform for developing, running and managing AI agents.
It lets you create multiple agents, configure them via the web console (such as LLM parameters and system prompts) and manage their plugins and functionality.
The system is fully plugin-based, where each plugin is a WASM program that exposes functions/tools that the agent can call, and can also hook into the query lifecycle. Because plugins are WASM, they can be written in various languages such as Rust, Go, TypeScript etc. Plugins can also act as libraries, which is possible because of WebAssembly Components (a great piece of software!) -- so you can dynamically call functions from other plugins within your agent, and you get type support for your chosen language too (with codegen via WASM Components tooling).
More recently, I've been working on an SSH server for agents. The idea is that you can add public keys to your custom agent and then SSH into it to talk to it easily from terminal.
If this sounds interesting, feel free to join our Discord! The project is still new and feedback is highly appreciated. http://asterai.io/discord
I'm prototyping a Depth Anything[1] -assisted segment annotation tool, with an eye toward plant detection in non-agriculture environments (where the backdrop is an endless sea of green complexity). Even if the task I have in mind doesn't pan out, I think this tool could be useful to people for other difficult segmentation tasks.
I'm in the midst of a tectonic career shift, from being laid off from a position and place I loved, to another gig while I keep looking for another unicorn role like before.
So most of my project work is home-based, after years of being able to chase (and execute) dreams at work.
On the technology front, I'm finally investing in a proper network core for home. WiFi 7 AP, 2.5Gig core, PoE everywhere, zone-based firewall. Still mapping out DHCP scopes and VLANs, but once that's done it'll be moving on to proper IoT and Home Assistant build-outs to prepare for the Unfolded Circle 3 later this summer. Also looking to redo my two N100 hypervisors off Proxmox and back to RHEL + Cockpit, or some other Linux + KVM implementation; from there, it's all about Kubernetes, Ansible, and Terraform. Really just a lot of oft-postponed side projects because I had amazing fulfillment at work, that I suddenly have ample time for now.
Outside of the tech stuff, I'm still trying to get some decent photos of two local birds of prey that have been hunting in my neighborhood. They seemingly spite me by only showing themselves when I don't have my camera with me, but dangit, I will photograph them.
On the writing front, I've got a few topics jostling around in drafts: speculating on potential futures of LLMs, the internet as a psychohazard, and a series of "fundamentals" to try and teach my non-techie circles more about how computers and the internet work, so they can do some modest self-hosting and get off centralized services. I'll likely dovetail some of them with my own home projects, writing them alongside the documentation as I make progress.
I have revived my work on Go Micro (https://github.com/micro/go-micro) and rewritten the v5 cli/api from scratch (https://github.com/micro/micro). As a VC funded company there was a lot of confusion around the tools we were building and we veered off in a direction that alienated the community. With the company dead, funding gone, etc there's an opportunity to rebuild value around the Go Micro framework.
The second thing I'm working on is the Reminder (https://reminder.dev && https://github.com/asim/reminder). As a muslim I feel like it's my duty to spread the word of Islam and as an engineer I feel like an appropriate way to do that is build an app and API for the Quran, names of Allah and hadith. It's a slow patient building of something as opposed to expecting anything from it.
In terms of new ideas, maybe not new but less screen time, less phones, more nature.
Hi all! my name is Patrick and I'm a linux platform engineer out of Waterloo Can. This ( https://imgur.com/a/14YMyVN ) is a collection of Nesticles - lightweight isolated immutable desktop system containers using modern linux compositor technologies and shown on a debian stable host platform and targeting PC grade hardware. These are getting very useful and present opportunities to theme and deeply customize for your personal use or for an organization or company. On average they consume like 600mb of memory per running container, so you will see ~30 envs running there comforably in those screenies. Nesticles is also a platform for unifying desktop and app delivery, providing some building blocks for composing up useful containers. Currently these environments are specified as docker-compose projects, including all of the apps. Could anyone see these becoming useful to you? It kind of scratched a 20 yr itch I'd had since being a young lad configuring desktops painted on cubes and such. I'm shooting for initial support for the following host platforms (debian, ubuntu, steamos, windows, mac). I'd like to bring a launcher to Steam to fund dev and bring the core definitions to the community perhaps as open-source container definitions. Any suggestions or thoughts on Nesticles or lightweight desktop containers? I do view these as building blocks in some larger or more specialized system, but they have utility for desktop use cases now. Ps. I'm also currently on the job market if you are looking for a platform/backend developer - please see https://paddymahoney.github.io .
Thanks all, Patrick.
A very misguided project that started with me trying to run Linux on a newly acquired 386DX-40 and has led to me building my own Linux distribution for said purpose
I'm still tinkering on my multiplayer game server framework when not grinding away at my day job.
The idea is essentially: An Erlang-based control plane, supporting ENet and WebSocket connection modes, with Protobuf for messages. Erlang has an excellent concurrency story, and I think it's a great fit for game servers. I've wrapped up a bunch of this work into behaviors on the Erlang side, such that developers can target the "gen_zone" behavior (for instance) to implement a tick-based game server. I'd like to expand that into other types of games, such as turn-based games.
I've also got a Godot plugin for generating a client library based on your protobuf schema. The plugin handles session stuff, exposes functions for client-to-server messages, and emits signals for server-to-client messages.
These days I'm working on integrating Luerl (Lua in Erlang) and Love2D support. I want to be able to take advantage of Erlang on the back-end while writing the majority of game logic in Lua. Further down the road I want to explore hot reloading parts of the Lua game state on the client/server, perhaps with an in-game editor, to develop the game "inside-out", in a way.
Writing a complete API client for the Internet Archive in Typescript, with proper documentation, proper typing, unit tests and integration tests, so people can have a proper library for both front-end and back-end applications.
Im working on a Discord Bot that can spin up game servers on demand. We are two developers, me and my friend from uni. Its called SLASHPLAY (https://slashplay.gg) . We are trying to make it as convienient as possible to spin up a game server for friends or fellow gamers. Currently we are trying to find out if we can make a living from it :?
It’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. The first two cards are unsigned, and the last one reveals who sent them. It’s meant to be a slow, kind surprise in the mail.
I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!
A Markdown-first CMS and website builder for blogs, newsletters and documentation websites.
I've been blogging since more than 10 years, and the only thing that made it possible is Markdown. That's why I've decided to build a complete publishing platform to replace the complex and fragile setups of bloggers and startups. Do you really need a CI/CD pipeline, static site builder, hosting, CDN and analytics just for a website? :/
The platform is currently 100% operational and I'm now working to Open Source it.
The best thing? You can publish directly from the CLI:
Recall Audio - A multichannel audio recording app that has your back, even if you forget to hit record.
Basically it continuously records into a buffer (length is configurable), and if you realize that you wanted to start recording 30 minutes ago you can recall the buffer and have everything saved.
In my work and an audio engineer I was in this situation a couple of times, and since there was no tool for that on the market, I’m building it.
I've been trying things for 25+ years and I'm about to kick off a test of a whole bunch of new business ideas. You might have read my article, How to Lose Money with 25 Years of Failed Businesses.
Recently started building a rules-engine for Warhammer 40k, so that I can finally play a game RTS-style in the browser. Hopefully one day I'll get to a public lobby / matchmaking (think chess.com for WH40k).
It's something I've been thinking about for years, but kept avoiding because I knew it'd be a huge commitment and I figured surely someone else would do it eventually. But I decided to finally tackle it and learn some new skills. 40k has literally 1000s of special rules across all the armies, so it's been fun designing a highly modifiable architecture.
Talo makes it easy to add systems that traditionally need extra non-gameplay build time like authentication, player analytics and game stats.
Right now you can drop Talo into your game or use the API directly. Importantly, I’ve made Talo easy to self-host and you can point the Unity package/Godot plugin to your own Talo instance.
I’ve been working on a side project called jobswithgpt — after months of building and refining, the first version is finally live: https://jobswithgpt.com
The idea is simple: a job search site that actually works for job seekers. It focuses on listings posted directly by companies (no spam, no middlemen, no bloated sponsored posts drowning out real opportunities). It uses AI to surface better matches, recommend jobs intelligently, and pull out the most important info from job listings automatically. You can also bookmark jobs you’re interested in and track them easily — no signup needed unless you want personalized suggestions.
It’s still early, and we’re improving it constantly. Would love for you to check it out, try a search, and let me know what you think — good, bad, rough — all feedback helps. Thanks a lot for the early support!
Learning Rust by building a simple database using it.
I’ve done my share of programming languages (PHP, C++, Python, Ruby, Haskell) and for the last 10 years I’ve been working in OCaml (which I love so much) but Rust would be a nice addition IMO.
And I never implemented LSM style database before! So that’s fun.
As a freelance web dev who also has an Airbnb side hustle, I got tired of expensive bookkeeping for a few transactions per month. I tried DIY, but my time is worth more than that.
Most importantly, both pros and DIY got subtle things wrong and caused me to miss out on thousands of dollars in deductions and credits.
So I’m making an AI bookkeeping chatbot that will handle all that for me. The aim is full automation while surfacing tax deduction and credit opportunities throughout the year. Like wouldn’t it be awesome to just have the research and tax credit or do home office deductions with zero effort?
At the end of the year, Kumbara puts together a series of financial reports that you plug into your tax software or hand to your CPA.
Working hand-in-hand with CPAs and some platform partners on this. Would love to hear from other solopreneurs or engineers who want to help build the future of financial freedom.
Last year I bought a broken jukebox. I wanted to convert it to be powered by a raspberry pi. I wanted it to work like a traditional jukebox where you used the buttons to input the song number. While there are a few existing projects to convert Jukeboxes to run from raspberry pi, most of them used a touch screen or didn't work well on RP5 which is what I had or the current version of raspberry pi os.
So despite not being a programmer, barely knowing a little javascript, and nothing about python, linux, or gtk, I was able to use AI to muddle my way through to creating a program that takes the input from a numpad, looks up the song from a list, sends it to mpd, and posts a picture from the album art embedded in the music file. https://github.com/jccalhoun/mpcButtonJukebox
I started a functional beverage brand about 2 years ago and rebranded for larger scale about 7 months ago. I am located in South Florida and have had some decent success so far but still investing all profits back into the biz. Raised about $50k of outside money.
If you're in South FLA and are into fitness and health, consider reaching out to me or responding.
I will also have the capacity to sell in to the NYC market quite soon. If this sounds interesting, again, please respond or DM!

A little free library style box, but not free and not a library (https://thingio.dev)
I've got an LTE module connected to a solenoid lock. The module listens for a "checkout complete" callback from a Stripe payment link which will unlock the solenoid. There's also some weight sensing involved to track the current product inventory inside the cabinet.
I built this for a family friend who does a lot of wellness outreach around combating food deserts by introducing small scale farming to local schools.
As a result of their community bee hives, they have a bunch of excess honey. So, I thought I’d build them this little honey vending cabinet for their neighborhood.
I've expanded the service a bit to be more product agnostic, maybe someone else can find a use for it.
I'm working on Damon[1], a Nomad Events stream operator that automates cluster operations and eliminates repetitive DevOps tasks. It's a lightweight Go binary that monitors the Nomad events stream and triggers actions based on configurable providers.
A few examples of what it can currently do:
- Automated data backup: Listens for Nomad job events and spawns auxiliary jobs to back up data from services like PostgreSQL or Redis to your storage backend based on job meta tags. The provider for this is not limited to backups, as it allows users to define their custom job and ACL templates, and expected tags. So it can potentially run anything based on the job registration and de-registration events.
- Cross-namespace service discovery: Provides a lightweight DNS server that acts as a single source of truth for services across all namespaces, solving Nomad's limitation of namespace-bound services. Works as a drop-in resolver for HAProxy, Nginx, etc.
- Event-driven task execution: Allows defining custom actions triggered by specific Nomad events; perfect for file transfers, notifications, or kicking off dependent processes without manual intervention. This provider takes in a user-defined shell script and executes it as a nomad job based on any nomad event trigger the user defines in the configuration.
Damon uses a provider-based architecture, making it extensible for different use cases. You can define your own providers with custom tags, job templates, and event triggers. There's also go-plugin support (though not recommended for production) for runtime extension.
I built this to eliminate the mundane operational tasks our team kept putting off. It's already saving us significant time and reducing gruntwork in our clusters.
Check out the repository[1] if you're interested in automating your Nomad operations. I'd love to hear your thoughts or answer any questions about implementation or potential use cases!
It's a translation map of Indian languages - type in a word, see the translations across 22 languages.
I was inspired by this HN post (https://news.ycombinator.com/item?id=43152587), and wanted to make something similar for India (which has similar linguistic diversity). Translations are fetched with Google Translate, but I also display 'romanizations' (transliterated into Latin script), which are generated with a local ML model.
Now that it's done, I've mostly been working on a little Markdown-to-HTML parser in Haskell.
We're working on the successor to Weebly, with https://www.articulationsites.com. My partner and I were founding engineers at Weebly. It's clear that the brand is in decline at the hands of Square, and it drives us every day to make a great alternative that Weebly users can rely on.
I'm working on a universal tool to create and print custom dust jackets.
I like collecting books and have lots of series, but editions and cover/spine designs changes all the time for no good reason. Especially for long series it's near-impossible to get a collection with consistent styles, which I find frustrating. And when buying rare or old second-hand books online, it's even worse.
The app will allow you to enter your book information (title, author, size, summary...), then choose the design/layout. You will then have the option to print it by yourself (for free - if you can find a big enough printer) or get it printed by a professional.
A simple coffee shop app that shows the nearest coffees shops that are closest to you. Using Google's AI, each shop has a Gemini AI overview that describes the shops offerings and other information that might be useful to the user.
I've only built it for Minneapolis and Chicago for now.
I’m working on LookAway (https://lookaway.app) to help people stay healthier and more productive during prolonged screen time.
My main challenge has been making meeting detection more robust -- it currently uses both mic and camera activity, which led to a lot of false positives. In the next version I’m switching to mic only (the camera caused most of the noise) and I’ve added a way to identify which app is using the mic, so users can exclude non-meeting apps.
I’ve also added plenty of small tweaks throughout to make LookAway even less interruptive. I’m excited for the next release!

I recently found out my wife wants a gecko, so I’ve begun planning for a mega-paradise. I want weather systems, every sensor I could possibly ram in there, cameras, and more. Planning to jury rig a toilet setup to run water from the reservoir to the rain system.
The gecko comes from New Caledonia, so my goal will be to replicate that environment as closely as possible. This will be difficult, since most of the plants on the island are only found there, but you can get surprisingly close.
One awesome fact I learned about this: conifers actually started out in warm climates. They just got out-competed once angiosperms (flowers!) came about.
A Chrome extension to track your research progress.
You give a title to your research session, and it keeps track of which tabs you have opened, which ones you have read and have not read.
When you want to resume your research, you can simply resume on whichever research session you want, and it will reopen all your tabs as before, so you can continue from where you left.
Erlang-RED[2] a combination of Node-RED[1] and Erlang to create a visual low code programming environment for Erlang based on the principles of flow based programming.
Reached a milestone today by being able to create a http endpoint and route the traffic (based to path variables) between various pathways. Thus it is possible to create a blog using Erlang-RED - what all good frameworks should be able to do ;)
I just finished a small personal project: a self-hosted web app which stores and indexes my archived emails. None of the existing options I tried were very good so I made my own. A simple Rails app that ingests .eml files and stores the text in postgres for full-text search.
I learned a lot about text encodings, multipart emails, inline attachments, postgres' tsvector/tsquery, etc. I'm particularly proud of how I was able to use `WITH RECURSIVE` to get an email's entire thread, which seems basic but the other archive apps I tried didn't have that feature.
Whispers is a self-organizing, belief-driven mesh where nodes propose, verify, and evolve solutions through dynamic, decentralized consensus.
Basically a shared knowledge graph of proposed partial inferences in CRDTs using verification as a merge function. There're some issues I know I'll run into with e.g. admissibility but I have some solutions in mind.
I'm in the very early stages but I think it's a simple idea so I have high hopes for a cool demo soon.
Need to renovate an old house, built in the 50's, extended later in the 60's, 90's and 2000's. I want to calculate the heat loss, energy requirements to install a heat pump. So, I am writing a relatively simple Python program to compute the heat requirements (max total and max per room) to get the possible energy savings if changing windows, isolating etc.
By doing the calculations myself, I can play with different scenarios, I can also integrate the effect on the material quality uncertainty. Nothing fancy, but it fits my needs.
I'm working on a little 2D action puzzle game in Go on top of SDL (with bindings via https://github.com/veandco/go-sdl2). The prompt I've given myself is "Chip's Challenge meets Hotline Miami," but who knows how much of either of those elements will remain after I keep evolving the capabilities and general feel of the gameplay. For dev graphics I'm just cobbling together sprites from various pixel-arty asset packs I've purchased on itch.io, but in the future if I want to commercialize it I'll probably want to work with an artist to develop a unified look-and-feel for the game--I may even switch to 3D/2.5D depending on how the tone and my workflow evolve.
I've experimented with Unity, Godot, and GameMaker in the past, but for the time being I'd like to see what I can accomplish on my own in Go to keep my dev chops sharp especially since I've moved into an engineering management role at my job (which has nothing to do with game dev but is increasingly employing more Go source throughout). Something I've realized as I've been applying good code organization and reusability is that I'm essentially building an engine for anything top-down (hesitant to say "isometric" since I know that means something graphically specific)--RTS/TBS/tactics/RPG all seem doable with what I've built given a little bit of extra logic on top for each.
I was inspired by this comment https://news.ycombinator.com/item?id=43745615 and built a simple workflow to process all my photos: for each photo it generates a text description, a list of keywords, and the mood.
My plan for the next step is to detect faces, ask the user to label the most occurring faces, and then label all images accordingly. This step seems a bit harder than just feeding the image through Gemini and asking it to create labels.
This is going to sound ridicilous. But in the past month, I have been working on an AI agent that can write its own AI agents. I can give it a task like: "Please create an AI agent that fetches the weather, and sends me an email every morning about some interesting stuff to do". The agent then goes through a loop of requirements gathering (with my input), and then starts building himself.
It self-references its own documentation, spins up a docker container and runs it. Alongside it builds tools, and registers both the agents and tools in a central system, so that it has knowledge of what other tools and agents it can use. I am not talking about "I am working on the theoretical idea of an agent that can build agent", but this is actually working. And I know of several other teams that are building stuff in this direction, its very fun.
I left behind a very well paying client to go full-time on this because its just so much fun. I have connected it to telegram, so now while I am at the gym, I can actually build software... the execution may take anywhere from a 10 minutes to an hour. Which is time spend writing and testing the code, then spinning up a docker container and fixing stuff, prompting me to create accounts somewhere an provide an API key. By far its the most complex project I have worked on, and all my friends and colleagues are slightly going crazy by seeing the outputs.
My primary goal is to make a game that's fun. Secondary goal is to make you experience why an AI might do things you don't expect. Specifically, to further instrumental goals like collecting resources, refusing being turned off, things of that nature.
There are two endings currently but I'm working on adding some more.
An IDE for agents, that includes a general purpose agent inside so developers don't need to start with a framework or from scratch. It just works, out of the box.
I feel that the software development lifecycle for agents is uniquely iterative and requires a different set of tools and environment, so that's how this came to be. First we built the general purpose agent -> now we build the IDE around it.
I’m working on extending Postgres to run on top of FoundationDB. The goal would be turning Postgres into a distributed, horizontally scalable database with automatic sharding and replication.
Hoping to share a first version of it soon. It’s been absolutely fascinating digging into Postgres internals!
Want is a hermetic build system, configured with Jsonnet. In Want, build steps are functions from filesystem snapshots, to filesystem snapshots. Want calls these immutable snapshots Trees. Build steps range from simple filesystem manipulation and filtering, to WebAssembly and AMD64 VMs.
I'm working on an app for collectors that comes with an inbuilt, curated database where users can mark things as having, wanting and/or selling. It will have an invuilt marketplace soon, but currently I'm using links to external sales to cover the supply side. I'm also starting very niche by just covering Neo Geo games, systems and accessories for starters. https://sumthings.com
Last month, I started playing around with code sandboxes and how LLMs might interface with them and wrote a little blog post about it [1]. I then took the code and vibe coded my way to a multi-tenant (untested!) sandboxing server that lets you run arbitrary Docker containers and provides a simple HTTP interface and UI. A cute, novel idea is that you can fork containers easily, as seen in the video in my repo:
It may not be useful, but it's been fun, and I've honed my gut-level experience in Docker, Podman, Linux namespaces, Checkpoint/Restore, CRIU, and more. The ultimate goal is to hand each AI agent iteration a sandbox of its own (forked from the previous iteration), and have it build apps in private sandboxes. You'll be able to view intermediate progress as the app is being built (or failed rabbit holes), since each sandbox gets a unique URL automatically. Like, imagine if each commit of your git repo had its own URL to preview the app!
I'm working on a pure js webgl image editor with effects, filters, crop & perspective correction, ... oh and it's opensource as unfortunately most comparable solutions are closed sources
I've been working on a web app that tracks ammo prices from various US ecomm merchants with the shipping costs included. It also tracks price trends and historical prices. Added some tools for enthusiasts to calculate trajectories, recoil, and compare calibers. Using rails, it's been fun and is generally a joy to work on, have learned a lot. https://ammosight.com
It's been a lot of fun getting the basic tools going: transliterators, morphological generators and analyzers, and some other things on top. But the main goal is to improve fluency as quickly and efficiently as possible.
Little personal project that started as a means to try out AI tools that can talk to each other. Turned out to be super useful for building and debugging complex AI automations. I haven't had the time to promote it. But maybe someone here will find it useful.
(1) Business process modeling tool where processes are data and not graphs. I am doing it according to the USM method. USM is kind of "open source" service management method, although it works on different level than other frameworks and standards, and is compatible with all of them.
This makes it possible to create a kind of requirement "programming language" where the requirements can be evaluated. With this language it becomes possible to create cross-references from various compliance standards/frameworks, like ISO27K, to USM, and automatically evaluate the compliance.
(2) Dance event calendar in Finland, running in production for over a year. 1-2M page views/month. Django app, but I am now implementing a copy of the unauthenticated user views to S3 bucket and delivering it through Cloudflare.
(3) Django app to handle all the data related to custody trial. Emails, SMS, notes, official records, voice memos, etc. can be attached to a timeline, and tagge and searchable. It has command line interface for adding data, in addition to UI, so I can quickly add notes and attach files.
- Shows I can use AI and I've integrated into AWS Bedrock
- Shows I can integrate with Stripe for payments
Consulting (Architecture, Strategy, Tech) - I'm working on getting my consultancy started. If anyone wants the kind of skills I offer here let’s talk https://architectfwd.com
Next SaaS - Starting a SaaS for managing core strategy and tech concepts. I created goals for it but I’m failing to kick the tyres
Last night I actually also started playing with firebase studio, though the app I prompted isn’t even doing save of the document properly. I figure can’t be me but will try again and work through the errors.
Positron, a data science IDE. Has roots in RStudio but it's built on VS Code and has robust support for both Python and R workflows. If you use VS Code and install a bunch of extensions to try to make it a competent R/Python data environment, you'll probably love Positron.
Scratching an itch, the intention is that its a map, centered on the users that shows all (configurable) things of interest near by. Think of Atlas-Obscura but much more local - eg AO doesn't list every prehistoric burial mound on the planet, but I want to know where they are ;)
I wrote a novel in French a couple of years ago that I want to translate to English. The way I do it is paragraph by paragraph: copy/paste a paragraph in OpenRouter (Sonnet or Gemini), get back the translation, and rewrite/adjust it.
It works well but copying/pasting back and forth gets old very fast, and it would be better if the process was done inside the word processor. For some reason (various reasons) I still use Office 2003, which doesn't have any AI feature. (It does have a "translate" function but it's awkward to use and not very good.)
So I wrote a macro to send selected text to OpenRouter and replace with the response (with a system prompt that says to only output the translation, otherwise most models start with "Here's the translated text:")
I had never written a macro in vba; I got started with Sonnet and adjusted many parts with the help of StackOverflow (which turns out to have more information about vba than Sonnet...)
And finally it worked; and it turns out to be an incredible boost to translation productivity!
An easier and more secure way to work with secrets during local development. It’s open source, cloud/vault agnostic, and doesn’t require a single line of code change to use. I call it RunSecret.
RunSecret is a CLI that replaces your static secrets with “secret references” in your ENV VARs (or .env files). These references are then replaced when your application starts up by reaching out to your secret vault of choice - making your .env safe to share across your whole team and removing a slew of gotchas when you use git ignored env files. Even better RunSecret redacts any instance of these secrets from your application output, reducing your chances for accidental leaks.
The approach is inspired by the 1password CLI, but built for the rest of us. I’ve got AWS Secrets Manager support pretty well baked, but the goal is to support all major secret vaults within the next couple of months (Azure KeyVault is already in progress).
I love exploring data, but it always felt clunky to juggle multiple tools, write code/commads, just to import and query a dataset. While there are multiple GUI tools for databases, none are focused on raw data.
TextQuery is the tool I built to solve that. You can import CSV, JSON, and XLSX files and start querying them instantly using SQL. Want to create a chart? Just hop over to the Visualize tab.
I'm also rolling out a major update this week — adding tabs, filters, a redesigned UI, and keyboard shortcuts.
Looking ahead, I’m planning to expand support for more formats (like Parquet and ORC) and data sources (like Postgres and BigQuery), so you can import data from anywhere, and query it right from your desktop. Something like a local data warehouse. With Apple Silicon, the capability of a desktop can make it very cost-efficient compared to something like BigQuery, Snowflake, or Athena.
It only stores (timestamped) floating point values with a series id and uses a B+Tree as the backing data structure. Querying is done with a lisp-like query language.
https://mujo.app I’ve been building a minimalist productivity app for musicians. Mujo adds time tracking, task management, notes and other “practice journal” tools into a simple metronome interface. Been hacking at the iOS version for a while, and starting to think about Android.
A reactive notebook with managed side effects for building backend/AI-engineering pipelines.
Reactivity can update the state of the notebook automatically, so you don't have to keep track of which cells to execute again. Side effects are managed to make it easier to reason about while maintaining reactivity and ability to interact with the outside world.
I'm working on a correlation matrix with Svelte 5.
It has hierarchical clustering, rolling correlation charts, a minimap, time series data detrending, and 2D matrix virtualization (to render only visible cells to the DOM).
It has up to 130K matrix cells and correlates up to 23.5M time series data points.
Debugging co-routines / threading is a pain in any language. I'm a big believer in observability anyway so this isn't a leap. Nor is it the first time I did this very thing, but last time I had implemented a console and it was a console command. This is in a product written in Python which implements a DNS gateway for Redis:
MindJam helps brands, studios and creators understand their YouTube communities.
MindJam analyses millions of YouTube comments to instantly reveal the unfiltered voice of your audience – their true sentiment, emerging themes, and the topics they really care about.
I didn't intend on building MindJam... I wanted to learn about LLMs.
At first I wanted to see how Laravel would/could work with an LLM and after doing some reading I ended up learning about OpenAPI 3.0 Schema and Multi-Modal RAG.
In the last few months I have built on top of Gemini, Claude and OpenAI. All have their perks and quirks.
I am hoping this learning is only the start of a pretty cool journey.
the process of creating APIs for testing and automation should be as easy possible. the tools that exist nowadays for this purpose aren't good enough IMHO, which led me to build it.
I'm working on running sequences of heap operations (insert and delete-min) in linear time instead of O(n log n) total time. It's a silly little project in theoretical computer science I have.
Crucially, to make this bound work, you only learn the final state of the heap, not which element got deleted when.
Working on: Pantry Recipes – AI meal generation based on what’s in your kitchen
Over the past few weekends, I’ve been building Pantry Recipes – a mobile app that lets you quickly generate recipe ideas based on the ingredients you already have at home.
The idea is simple:
- Save or quickly select ingredients you have on hand
- Tap Generate Recipes and get ideas instantly
- You can also describe what you want to make free-form (e.g., "cheese omelette") and the app will generate a recipe for you.
So far it has some sort of activity calendar + expense tracker
There's still so much ideas to implement, like adding map, improve UX of creating activities, to-do list, etc
I've used it once or twice of a short trip, but in 6 months time, I'll have a 2-weeks trip, so that's my self-imposed "deadline" for this project
Anyway this project is a pure static web page and all the 'back-end' is handled by InstantDB ( https://www.instantdb.com/ ) after I saw their submission on HN >.< So far it has been quite a good experience overall except maybe the permissions model which can be a bit confusing to me
Main work: tokenization of real-world assets, but on the side I’m building two projects as a solo dev:
- XRoll.io — a fully on-chain gaming framework on the XRP Ledger, inspired by SatoshiDice but built for compliance. Commit-reveal fairness (HMAC_SHA256(secret, bet_txn_hash)), full transparency on-chain. Integrated KYC, AML, self-limits at the protocol level. Frontend is optional; ledger is the source of truth.
- Nexula — an evolutionary image generation system. Embeddings extracted with CLIP, clustered via HDBSCAN, visualized with UMAP. User behavior (time spent) drives fitness scores; top samples recombine through weighted interpolation to generate new images. Built on Django backend, session-based personalization without login.
Looking for like-minded people interested in exploring both the technical and business sides of these systems.
I'm working on an unified MCP server that can search and use a large number of tools. The current way of using MCP server (adding each MCP server directly) simply doesn't scale.
If your AI agent needs to use 100 tools, you need to manually configure a lot of MCP servers. And when you feed those tools to the LLM, it may get confused and tool calling accuracy starts to drop.
This is why I'm building a unified MCP server with just two meta tools:
- Search Available tools
- Execute a tool
When I want to send an email, I ask LLM to use the Search Meta tool to search for Gmail related tools in the backend, then the meta tool returns the description of relevant tools. The LLM then uses the Execute meta tool to actually use the gmail tool returned.

I recently started working on a fishing journal/log kind of app. I got that idea last year when returning from fishing with dad, that it would be nice if we could track what we caught each time we went fishing, where we went, and to track some details (water and wea details). There apps that already do that, and one could also use Excel or just paper notebook, so I'm making this mainly for us and his friends to use. It's still early, but I'd like to add groups so you can exchange messages or catches with your friends, add stats allowing you to see for example at what time and where you caught most fish, or using which lure or bait. The app is in Serbian though, but here's a link if you want to check it out: https://buckaros.com
I’m building a small integration to take scheduled transactions in YNAB and display them in any normal calendar application. I’m hoping to add historical transactions one day as well to help with reconciling.
I once saw an idea on here[1] about putting a lot more historical information into a calendar, including past activities. It resonated with me and I wondered if bank transactions could be part of this activity layer. At the time I was working on a real-time integration between my bank and YNAB so I was already thinking about the space.
Working on launching a podcast and associated website which I hope to use as the launchpad for all my ventures going forward. 2025 is the year I ditch my corporate job and finally start working for myself. At least, that's the goal. I'll be the master of my fate; the captain of my soul.
I know its been done before but im building/tinkering on a window manager for windows called "Doors". https://github.com/A-Waters/doors
Ive got a MVP right now, but i'm reworking the region build system and potentially reworking the underlying designing to follow a more tree based approach for managing the windows
I've just tried other windows managers on windows and felt that have either been slow or buggy and wanted something that looks nice. My inspiration is based on Hyperland, as im currently dual booting and when I work on windows, all i want is a nice window manager.
still very early in development but im excited for its potential.
This also goes in line with my current studying of the windows OS, so its a bit of learning and then working. :)
Work wise I'm building a discrete event simulation with pysim. I manage the autonomous vehicles program and underground control center for the subarctic mine I work at, and we've desperately needed some means to evaluate efficacy of designs and forecast productivity. Using it to model scoop-truck movement and loading operations, and it's working very well. It's been a joy.
I've been taking advantage of the enormous context window of Gemini 2.5 pro to have it make upgrades, fix issues, and just generally doing all the legwork.
Personally I'm having fun learning some web design and three.js as I try to debug the very tricky issues with my new personal website loufe.ca using AI is fantastic but you need to micromanage when things get complicated, I find.
I'm working on a better frontend (in sveltekit) for Udio - music generation app. Udio has good models to generate audio, but awful UI and organization/management tools. My frontend allows collecting all the generated content from udio, organize them by topic, rate them with 5-star rating system, add custom labels, filter by these, make playlists, generate prompts and create an arbitrarily long generate queue (udio allows you to create 4 prompts simultaneously so you can sit in front of UI babysitting it if you don't have custom tooling and you want to actually use your 4800 credits you paid for). I use LLMs heavily here, so the quality of code is so-so, but work very well for me and I'm having a lot of fun with this.
Mostly on an AI-based tender analysis tool which is focused on the construction industry, https://www.tenderstrike.com
It's a pretty specific niche with interesting challenges like massively varying project sizes (ranging from a few pages to 20,000+ documents), a high importance of graphs / charts, and very different extraction tasks (from more qualitative analysis to quantitative, exhaustive lists which is still a pain point).
Built most of the pipeline by hand, mostly because I started this earlier than many RAG tools came out, but I am glad I did because we needed a bunch of adjustments and changes that might have been hard with something ready-made.
I’m building ninja.ai — it looks like a one-click App Store for MCP Servers, but the real goal is much bigger: creating a “Universal Fabric of Context” that lets AI tools tap into structured information across the web easily.
It started when I found it surprisingly hard for my partner to install and connect MCP Servers — even simple ones. I realised if we want AI agents to really interact with the web, it needs to be as easy as installing an app.
Right now, you can browse, install, and connect servers in one click. Over time, it’ll make AI integrations as easy as installing an app — no messy APIs, no custom scraping.
If you’re working with AI models, agents, or data-heavy tools, I’d love to hear what kinds of “context pipes” you’d want to see added.
I’m working on JSON Query (https://jsonquery.app), a tool that lets you store, categorize and query JSON using jq in the browser.
This is a complete remake of the original I made a long time ago for the Mac App Store, sharing only the name. I realized it was better to use the jq language since it was already familiar to many people and way more powerful than designing my own query language. I also do not agree with Apple's App Store command and control so I've decided to make it a web app, and I'm astounded at how much more powerful web apps and their DX are compared to native application development in the Apple world.
Worked a little on Server Radar [1] again, the Hetzner Auction price tracker.
It's my fun little project to resort to. Implemented dark mode, sorting, grouping and various layout improvements. Also added a Drawer with Auction view the other week. UI is finally fun again with component libraries and LLMs.
Oh, and I added a Cloud Server Availability [2] page as I noticed people on /r/hetzner were complaining about lack of resources. Looks like their Cloud offerings are going quite well.
AI has taken over the hype in sales and go-to-market strategies. But for independents, solopreneurs, professionals, and many founders or CEOs, relationships and partnerships are still central.
I think sales will bifurcate: either fully automated self-sale, or fully relationship based. All of the major CRMs (customer relationship management) software are going all in on AI and sales automation.
I think relationship sales is going to see an increase in comparative advantage. I've always been a relationship seller but the current crop of CRMs are not designed for me. So I've built https://humancrm.io/ to scratch my own itch.
I work at a small startup trying to hire engineers and got tired of looking through resumes. As Joel Spolsky points out, they're not great indications of technical ability.
Instead, I decided to throw together a take-home challenge that applicants could access via an API. "If they can't solve the challenge, I don't need to see their resume," I told myself.
FizzBuzz.md is a better version of the solution I built for work. It lets applicants send questions and submissions to configurable email addresses via API so the email addresses aren't exposed directly. (Less spam, FTW)
Building an app that extracts key information from PDFs + highlights citations.
You provide a PDF and a JSON schema defining what to extract, and it returns the extracted values, the citations and their precise locations in the document.
This is especially valuable in workflows where verification of LLM extracted information is critical (e.g. legal and finance).
It can handle complex layouts like multiple columns, tables and also scanned documents.
Planning to offer this both as an API and a self-hosted option for organizations with strict data privacy requirements.
I was enjoying playing the game, there were some shortcomings in the info it provided, I dug around and found the info in game files, and decided to make that info more accessible. It was quickly a hit with the community and got official support from the game company. Trying to add enough features to take on the big players in this space and make working on it sustainable.
DodgeALL Party Mode! It lets people with smartphones connect to a player in VR (DodgeALL for Meta Quest) and decide which obstacles are launched at the player, that they then have to physically dodge in real life (there is no fake movement).
I also "recently" (~2 years ago) added Twitch interactive mode so that streamers could play against chat, but so far haven't gotten anyone to play it on stream (that I know of). While I was adding features, I realized that I could easily make a version that works over WLAN.
On the side I'm working on a mixed reality mode but it's been a slog trying to adapt the game to fit into various room sizes.
Working on a series of interviews with gamers about how the hobby is part of their lives, called Unmuted [1]. It's been awesome to interview people from different backgrounds and see how gaming has influenced them.
It's the first original piece of content for a newsletter of curated gaming content that I've been running for more than five years now, called The Gaming Pub [2].
Taking a break from my agentic AI framework for prototypes and makers arkaine(1) and made two fun useful apps for myself
1. Eli5 equations(2) uses an LLM to convert a given picture of an equation to latex and, if given additional context, breaks down the equation parts to explain it. Gemini for the model.
2. reflecta - a journal prompting app with deepseek to help reword and target the prompts towards you better.
Building a simplified inexpensive <20 nanometer accurate vacuum-tolerant positioning stage for microscopy and lithography projects. Trying to unlock the caveman achievement by keeping tools/budgets necessary to replicate the work accessible for other hobbyists.
Also still working on a custom Slicer for a special metal printer design. The VTK library version needed replaced by a simpler Blender Geometry nodes solution to extract texture information, and infill hull features.
Also considered a beautiful solution to Roger Penrose's Andromeda paradox. That guy has a wicked sense of humor... very funny. =3
My team and I are working on embodied AI. More specifically, focusing on humanoid legged robots for long horizon tasks combining navigation and manipulation/interaction.
The first is a preventive maintenance and calibration tracker (https://pmcal.net) that was born out of my day job as an engineer in small business manufacturing.
The second is an AI engine for pulling structured data out of incoming email (either via IMAP on your email server or via SES). If you think of the engine that powers TripIt, they had to write about 10,000 different ingestors for each airline and hotel and travel booking site. With a structured output AI, the need to write specific ingestors goes away.
Chrome extension to organize web-based learning into journeys. Uses the tab group API and sidebar to bundle a set of websites into a "container". Sidebar tracks progress through visiting the pages. Requires an LLM token for generating "packets" from a prompt. Requires s3 bucket token because it generates web sites just in time.
I'm working on a site that lets you tile and watch multiple videos from different platforms all at once.
You can drag and drop links from YouTube, Twitch, TikTok, or Kick --and they show up in a grid.
You can reload or remove streams without refreshing, save mixes for later, and share them as links. It works best on a really big screen --phones aren't really supported and even notebooks are too small to get much benefit.
There's no backend, no login --everything runs in the browser.
I am working on a telegram bot deployed on cloudflare which is just a basic app for van drivers to sign up on a fixed location near my area and see which drivers are online and see how many people have sit in a van which the drivers can increment/decrement by just chatting with the telegram bot who want to go to a popular spot where I have to go to quite daily because I am studying at a place which is way far away and its the most economical and sane method to travel..
Yet my problem really arises that its too luck based, sometimes I can be the last guy, Sometimes I can be the first guy so I have to wait for the van to get fully occupied which will take a lot of time...
I have just made it, and I find it pretty nifty, I made it all completely via AI and this one absolutely crazy good youtube video on deploying telegram bots on cloudflare...
Also, I had seen this telegram bot ai maker idea on HN a few days ago, So I had also created a project which you can chat with the microsoft deepseek r1 post training bot for free because the api key of open router for this model is free, It doesn't have incremental streaming or multi chats, really basic, and It can generate me the code but I am not sure how I would deploy that code .. , I used to think its easy but not... ,any resources out there? (Though I want to open source this, but I am not going to be building this ai idea further because I lack time and I have to study)
- Snapshot (https://apps.shopify.com/snapshot): AI generated product photos for Shopify. Previously used Flux and Stable Diffusion but always had quality problems. Was very tricky ensuring text remained the same and the product fit into the generated background. Just integrated the new OpenAI image generation model and results are much better however their masking feature doesn't work properly so need to wait for them to fix that before I can offer the same feature of keeping text/fine details the same
- Lurk (https://apps.shopify.com/lurk): New one I just launched - allows Shopify merchants to track the prices of competitors and adjust their own in response with dynamic pricing rules. It's cool because you just have to paste a URL and it uses AI to figure out the price. Again, there's a surprising amount of things you need to figure out to make this work reliably at scale (e.g. popups, ambiguous HTML, location-based pricing, etc.)
Started working on a case discussion platform for students almost two years ago. Mostly for dentistry and medicine, but it's template-based so works well for other purposes (e.g. teachers, social workers, etc.). It's going well and is being used by three universities right now.
On the way, I developed lightweight image editor and 3D model viewer components, which I've open sourced [1].
I used "Claude Code" to create a local-only webapp for tracking symptoms of my chronic sinusitis, which seems to be tricky for the doctors to figure out, over time, using the "Sino-Nasal Outcome Test" (SNOT-22) questionnaire. Trying to correlate environmental and medical factors and interventions with raises or decreases in my symptoms.
Currently working on a simple timing website for running and cycling race organizers. A manual 'just press a button when someone crosses the finish line' is already there, but now I'm experimenting with a printable QRcode that contestants have to wear. Once the QR code crosses the line, the time is registered.
All within the browser, so no apps need to be installed.

I’m currently developing Oliphaunt, a native macOS client for Mastodon, designed to offer a clean, responsive and fully native experience that feels at home on the platform. You can find more details, including screenshots and a project overview, here: https://github.com/anosidium/Oliphaunt-Feedback-And-Support. A new TestFlight build will be available soon, with plans for an eventual App Store release.
Currently working on a USB/Bluetooth to Sega Dreamcast controller adapter.
It's based on the Raspberry Pi Pico 2/W board and originally started as a fun project to play around with the PIO features of the RP chips and get my Steam Controller working on the Dreamcast. It has since expanded to support more controllers, keyboards, mice, and acts as VMU - the Dreamcast's memory card - while plugged in. Building the dongle itself has also been a fun exercise in 3d printing, cad and pcb design.
I'd really like to expand the amount of supported USB devices as I only have access to a limited amount of hardware that I can test myself. I've started looking into if I can use the SDL Game Controller DB (https://github.com/mdqinc/SDL_GameControllerDB) to kind of crowd source support for a bunch of controllers. I'm definitely open to other ideas though. I feel like I'm slowly learning that USB controllers are minefield of one-offs and edge cases.
It's inspired by VS Code and hopefully positioned to eventually be a Cursor-like experience for transactional lawyers. The LLM integration isn't baked in yet to keep the in-house onboarding frictionless.
It's a desktop application written in Rust. It uses egui (an immediate mode UI library) for speed.
2004 Lincoln Towncar. Recently replaced the intake manifold myself. Next is J-modding the transmission. Would like to replace gears with a different ratio for more power, but that will require taking it somewhere, not something I can do in my driveway.
Started my first garden this spring. Have several peppers, tomatoes, zucchini, and a few herbs.
Looking into internships and new opportunities. Been out of the profession for along while and need find my way back in.
https://www.accessgrid.com/ - The best way to issue and manage secure NFC credentials for Apple and Google Wallet via API.
No app required!
We took all of the complexity of issuing MIFARE DESFire enabled NFC credentials and made it extremely developer friendly. SDKs in most major languages (python, ruby, csharp, js, etc), developer console with request logs, and more.
After working on it for a while, I noticed there’s a stigma around using CORS proxies, often associated with fetching undocumented APIs.
While that’s sometimes true, I’m hoping to change that perception, to show that they can also be used for accessing real APIs. It just requires the proxy to correctly handle credentials and secrets.
The idea is to open up more possibilities for building static-first apps without worrying about CORS.
A open-source Looker/Data Studio alternative, supporting Bigquery/Snowflake/DuckDB. Has a custom SQL dialect with embedded semantic layer to make reusable and interactive visuals easier. Can be self-hosted, but a public version is available. Still very WIP!
I started experimenting and I think this builds out pretty neat estimations from jira tickets/other descriptions. When I was sitting in the CTO role, I spent a ton of time talking with people about how long/short various projects would be. When I was a developer, I hated the estimation piece because it felt like it was both keeping me from building and was almost never done with enough context to get really accurate results.
I was playing with the OpenAI API and I noticed that they can actually return a set of probability x next tokens and I thought that it might actually give you kind of cool ways to see the distribution of potential outcomes. (You can see an example here: https://universalestimator.com/estimates/c68db45b-7622-4bab-... that looks at a detailed ticket for implementing filtering on a dashboard.)
Let me know if you have any feedback, it's free with the promo code TYHN. If you run into any issues, please send me an email at earl@unbrandedsoftware.com
I am working on an administrative app for small shops. It has inventory, invoices, quotes, returns, purchase orders, payables, receivables, finances, etc. It's almost ready for v1, just finishing the final touches to start onboarding first users
Did a Show HN about a month ago, but we're hard at work building dédédé [1] - it's a not-for-profit website that invites people to casually share the "good, bad, and why"s of urban spaces.
So far this has means orchestrating a set of processes just to talk to bluetoothd, automatically connect to boards, guess which /dev/input/event* device each one is associated with, and start reading those and sending data somewhere over OSC. Every step of the process is about 10 times as difficult as I initially expected it would be, which is why, after months of work, I'm still putzing around with process orchestration instead of actually doing anything with music.
The bit of hair on this yak that I'm currently shaving is building a TUI library for Deno so that I can build a nice dashboard for keeping tabs on the state of all the different pieces. I prototyped a bit of the orchestration process in Node-RED, which was neat, but not exactly what I'm going for. There is a TUI library for Deno already, but it's kind of buggy and non-ergonomic for my brain.
Been working on https://www.labophase.com/ I mainly built it to save money on subscribing to multiple places to try out a new ai with a privacy focus.
Basically it's an AI aggregated service where users can prompt multiple ai models at the same time/place for free and/or under one subscription fee ($20).
You can email prompts directly to your ThreadWise address and get instant AI-powered responses, essentially an always available co-worker. Another great feature is the ability to schedule recurring tasks and since the AI has web access, you can get things like:
Daily mortgage rates or airfare price monitoring

Pull data from public APIs (and more)
So you can essentially use it as a personal newsletter, crafted to your taste.
The free tier will let you test this out for free! I am looking for some feedback/criticism, testing, and additional ideas and I am open for collaboration if you have experience with sales. Also open to hearing which scheduled tasks people would find most useful.
Why I built it: I noticed a trend online, as well as with family/friends, that people would like to have a quick access to AI in instances where they couldn't always install apps or use browser-based tools (such as in remote/low bandwidth environments). This is when it him me, email clients already have all the features needed to interact with an AI (text + attachments) and I quickly got to work.
Some of the advantages are also that since there are no new apps, or browser tabs needed, the tool is ideal for companies who don't have the bandwidth to setup full fledged AI solutions on their own. The companies can choose either between public LLMs (e.g. OpenAI) or host everything on-premise with locally run models, so no data ever leaves the premises.
I realised that I'm a horrible prompt writer and so are many other people. So i created this extension to help me write better prompts, using templates, save prompts, and optimize it for better performance. No login, not paid, just a useful little extension. Check it out!
I'm still working on Habitat. It's a free and open source, self-hosted social platform for local communities. The plan is for it to be federated, but that's a while off yet.
Just this weekend I began adding cypress tests. I can finally see an official release in the distance!
I have been working on a intentional farm to table co-housing network spanning from S.Flo, ATL ,to Cape Breton in NS CAN. It's been a humbling experience of meeting, learning and living with great interesting people to say the least. Each property is different but all are tailored to reduce hospitals readmission, provide various high risk groups housing opportunities, and supply fun lasting agrarian experiences. Each member has access, via provided transportation to the other properties and it's different resources. The struggle has been being a father of six, husband and career man alongside this project. I resign from my career almost 3yrs ago thats helped and hurt as struggling to secure income at times, I have learned and relearned alot! I can say I'm still moving forward and excited at what's ahead!

(open source) Self-hostable, private social media alternative (like Facebook circa 2012). Functionally it is a private blog that speaks RSS with a built-in RSS aggregator. Self-hosting being the only way to actually have privacy in a social-media-type space.
High definition model of the Sojourner rover to eventually produce a museum-quality copy showing the mechanical aspects (in particular the unfolding) and a robot mower for myself.
I develop Chips of Fury, a poker app for playing privately with friends. Currently I am building support for lots of home game variations like pineapple (regular, crazy, lazy), different Holdem variations like Super, reverse, super reverse, blind man's bluff etc and many more. I am thinking about how to implement AI bots for a wide range of variations.
I’m working on Vystery (https://vystery.com) - a visual puzzle game where you strategically uncover an obscured image bit by bit to figure out what it is.
There's a limit to how many reveals you can do to make your guess.
I’ve recently added hints, spare moves, and an easy mode, as some days are harder than others.
Building an app to reverse geocode all the photos I've taken and screenshots of places I want to go from TikTok/Instagram.
Use cases are extracting the itineraries I took from prior trips, then using that to ground LLM search recommendations: I have a set of bookmarked places, say in NYC, can you make me a week of plans given what I enjoyed in Taipei?
I've been working on onsite deployments for https://www.keystash.io, which is a Linux SSH Key and User management system. It's been going for a while now and I am finally implementing onsite deployments as so many customers actually want to run this themselves. When we started, we really thought customers wouldn't want the hassle of another piece of infrastructure to manage, guess we were wrong :-)
Onsite deployment is a lot more difficult to make slick and easy. We've been thinking about the best way for our customers to deploy while reducing the load on our support team. So far, we are thinking about RPM's, Debs and Docker and trying to make this as close to a '5 step process' as possible.
I would love to hear people's thoughts on other mechanisms that make it easier for SRM's / DevOps to manage key platform infrastructure software.
I’m building Cigaal, a super-ecosystem app that blends social media, commerce, payments, crypto rewards, and AI. Think of it as a lightweight alternative to WeChat, Grab, and Temu – but designed for underrepresented regions first.
A2A/B2A Agent Economy: agents handle cash deposits, deliveries, and API integrations with businesses
CoreIQ: an AI memory core that assists users across all Cigaal mini-apps (wallet, health, travel, shopping, etc.)
Why it matters:
Cigaal helps bring modern digital experiences to places with limited infrastructure, enabling creators, travelers, small businesses, and buyers to thrive in a shared economy without being locked into Big Tech platforms.
Would love feedback, suggestions, or partnerships – especially from people building in fintech, agent networks, or AI-driven apps for underserved markets.
A series of pulpy short stories, sort of a Dark Americana / weird fiction thing. Noir, magic, existential dread, horror. Warming up for a novel in a completely different genre but I wanted to iron out some of my own shortcomings and stretch some muscles before I write yet another 100k words on a project I'm unhappy with.
Working on Taskade (https://www.taskade.com), building the execution layer for AI collaboration.
Taskade started as a real-time workspace for teams to organize projects and ideas. It's evolved into something bigger — a platform where humans and AI work side by side.
We’re moving past simple chatbots into real agentic workflows, where teams can generate structured task lists, mind maps, and tables, train custom AI agents with dynamic knowledge, and automate work from start to finish.
Today, Taskade is built around three core pillars: Projects, Agents, and Automation. It’s like giving your team a second brain that can think, plan, and get work done across projects, automations, and real-time collaboration. If you’re interested in the future of human-AI collaboration, take a look!
I'm trying to read a kid's version of The Odyssey in Greek and to be able to understand my partner's mum, and these are the features that I wanted.
Also, I wanted to experiment with "what would an app like this look like if we could trust AI to be very cheap/fast/correct?".
- So, for example, it's a fully generative dictionary & search, e.g. the dictionary entries/metadata/example sentences don't exist until the first person searches for them!
- You can upload any kind of content (image, audio, text), and it'll automatically transcribe, translate, annotate, etc.
With 16x Eval, you can manage your prompts, contexts, and models in one place, locally on your machine, and test out different combinations and use cases with a few clicks.
It's compatible with Settlers of Catan. However, I plan to make my own rulesets, artwork, manuals, etc. It will not be a commercial product, of course you can make your own with the files I provide.
Right now the boards, electronics, and firmware are in good working order. Although the routing is pretty YOLO.
It feels like there's a lot of unpleasantness going on in the world right now. I thought maybe I could put my other projects aside and try to make something that might brighten your day (It certainly has enough of LEDs).
A big TODO is to replace the 0402 SMT components with something larger and easier to work with like 0603. I'll find time within a week or so and push it to the repo. (I am notoriously cheap and only keep 0402 in stock)
A language learning app for couples (https://couplingcafe.com). I wanted to learn my wife's native language, so I've been building this on my own for a long time and testing solutions! Just a few paying happy users. Cooking up a lot of ideas
WebSocket Router for Bun — A type-safe WebSocket router for Bun with Zod-based message validation. Route WebSocket messages to handlers based on message type with full TypeScript support.
A social advocacy platform for small and medium sized B2B businesses.
LinkedIn is more or less the only social platform for B2B social selling and smaller firms could benefit from their posts getting a bit more augmented and coordinated engagement. So we’re building a solution for a marketing manager to request advocates (employees, partners, others) to engage or reshare (tweaked in their own voice if they want) their content.
Not world altering but shockingly underserved market. With few players who raised money and therefore have to price expensively, whereas as a bootstrapped side-hustle we can offer it in a flat-fee way that doesn’t “penalize” growth by charging per-user or for inactive users.
I'm working on creating a volume mixer, basically like Deej, but more polished.
Some things I'm planning on including:
- App drag & drop for assignment.
- Programmable macro buttons.
- Small OLED displays to show app icon and volume levels.
Attempting to do everything in Rust too, even the MCU firmware. It's been a lot of fun. xD
I am working on making it easier to learn languages. We provide a platform for teachers and educators to create their own language courses. The platform offers features similar to software like Babel or Anki, along with some unique features for phonetics study and customizing the learning experience.
We're currently working with language influencers to build courses on Emurse. This year, we launched Japanese Phonetics course created by the YouTuber Dogen https://emurse.io/course/japanese-phonetics.
If you want to try out Emurse, we have a free Thai reading course available. You can view the first lesson without out creating an account: https://emurse.io/courses.
Working on specstory.com which today is an extension for Cursor & Github copilot that allows you to save, search, share your AI chat history.
Most AI first coding tools don't seem to respect how much critical context gets lost between sessions. Prompts, chats, refactors, decision paths all gone. Really believe that intent (prompts & responses from AI) is going to be the critical artifact upstream of code and there is a need to capture all of it: what the AI suggested, what you kept, what you rewrote, and why. We integrate directly with AI-powered IDEs so your intent becomes as searchable as your code.
We started with Cursor and just shipped support for GitHub Copilot (Agent Mode). The long-term goal is to build a canonical intent layer for codebases built with AI—something like git log/blame, but for why things changed, not just what.
For awhile I've been working on an MPE MIDI controller called the Mosaichord. It uses a tuning system called just intonation, where the frequencies of all the notes are related to each other by whole number ratios. I'm using a scale that has 28 notes per octave. Keys are pressure sensitive.
Something I'm working on right now is trying to implement a basic on-board synthesizer so people can use it without a laptop or external hardware synth. (I added a DAC a couple hardware revisions back, I just haven't done anything interesting with it yet.)
The firmware is open source and there's a fairly detailed user manual.
I'm working on a new kind of financial infrastructure that combines crypto, fiat, and AI to make managing money in decentralized environments simpler and smarter. The core idea is to move beyond the traditional 'wallet' model and instead help people, especially in emerging markets, make better, more informed financial decisions using real-time intelligence and automation.
It’s designed for everyday users, not just crypto-native folks, and it focuses on things like streamlining DeFi, improving transparency, and reducing user fatigue. We’re building with scalability and user experience in mind — something that actually fits into people’s daily financial lives, not just trading.
If you are very keen on working with me, I am building a team of devs too.
Working on a site to help people find stained glass windows to visit in their towns/cities. No exciting tech (vanilla HTML/CSS/JS) and lots of data entry, but making some decent progress!
Currently;
> Main goals: Improving my writing and finding some people with similar interests
Writing about my current walking season that I'm in, combined with reflections during the walking, recently about walking around the island of Menorca, and Aloneness:
Thinking about starting another Substack:
> Main goal: Audience growth
Called something like: "Walk more", "Walk intentionally", "Move intentionally", "How to walk more"
About: Short, (bi)Weekly, Practical tips/inspiration, to Move (and specifically Walk) more and more intentionally.
Still cracking away CodeVideo, a way to create software educational content in a declarative manner. Design your course once, export it to every format you can think of (video, PDF, markdown, HTML, and more). I was recently inspired by the feature set I saw at Scrimba, so we just added slide functionality! The blog post is here: https://codevideo.substack.com/p/introducing-the-slide-displ...
I'm building an interactive map based search interface for concerts and events in the bay area: http://fanflame.city/
This is something I've always wanted for myself so I decided to build it. Plenty of event aggregators out there, but not many that let you search and filter by any combination of locations, dates, and genres.
It currently supports automated data feeds from ticketmaster and the Civic Joy Fund; hoping to add Parks & Rec, Library events, and some other ticketing sites in the near future.
It has been a fun way to keep my coding skills sharp (Eng Director by day), I've learned a ton about react, mapbox, django, postgis, and GCP doing it. If you have an event source I should look into or a feature request let me know!
Recently I’ve pretty much replaced searching Yelp or TripAdvisor with a combination of Instagram Reels/TikToks and Google maps for travel and food recommendations. I usually just save a lot of places that I have to dig through and watch again to dig through and add to my saved Google maps lists. Because this takes me a fair bit of time when preparing for a trip, I decided to automate part of it by building a pipeline to “watch” the video for me by getting the audio and video frame data and taking into account key POIs that I then export out to a note. Later I plan to also integrate this with other travel or food tracking software like Wanderlog, Google maps list, or Beli eats. So far it’s been working well, but def expensive (so thank god for free GCP credits haha)
https://nuenki.app - a browser extension that translates sentences at your level while you browse, so you learn a language through immersion while you go about your day.
I'm also working on and off on a hardware device for blind people.
While Git is great at asynchronous collaboration, its a bit clunky to try and work on the same commit with other devs or across devices.
This is because Git tracks what changed, not how it changed.
It'd be cool if you were on the same branch as somebody else, or another device, and your working directories could be synced.
It'd also be cool for the commit history to be a bit richer, so you could see who, what and when for a change at a keystroke level.
So I'm working on real-time sync for Git!
I'd represent the working directory as a tree CRDT [1] and sync that through FUSE and p2p networking.
Not sure whether this is actually a good idea! This is a POC :)
so I'm working on side project to make managing and exploring your music library easier.
The idea is you can set a few filters (like bpm, key, decade, genre) and then swipe through random songs, accept or reject them for inspiration or playlists. Kinda like Tinder but for digging through your own tracks.
It also tracks what's trending on TikTok/YouTube/SoundCloud weekly, so you can find stuff that’s blowing up, filterable by region. Plus it can build smart playlists automatically based on rules you set (like “new 90s house under 120bpm” every month).
It is just a tool to make working with your existing local/Apple/Spotify/SoundCloud library faster and more creative.
https://www.lookoutwindow.com , read about the places you are flying over, and figure out which side of the plane to sit on. Map and wiki articles all work offline, in about a 10MB download for each route.
I'm trying to figure out how I can turn hobby products (that me and family and friends are using) into real products for a wider audience. So far, I've found 2 main failure cases:
1. While I can share source code and documentation with trustworthy people, that won't work at scale: the market would get flooded with Chinese clones that re-use my Open Source software but then I have no ongoing revenue to fund support / maintenance.
2. Especially for products with a physical component, shipping, taxes, refunds, CC chargebacks etc. add considerable overhead. Plus I need to add in Amazon fees and marketing spend. And suddenly I need to charge 8x the manufacturing price, which means I either need to massively cheapen out with quality, or it's going to be a very premium product.
A semantic music visualizer :) real-time capture of elements of music —- not tracks but true elements —- paired with time-stable frame generation for display. It likely won’t be as good as a real VJ, but I want to outshine all the visualizers which are basically a demo atop a grapheq.
I'm working on a long-term project to better understand Operating Systems, video game development, and Rust by building the simplest possible OS in Rust that boots directly into a game of Doom, which will also be re-written in Rust.
I'm giving myself 18 months- it's been super fun so far!
I'm working on a Kaggle competition about predicting subsurface models - a map of the geologic layers beneath a given area - from seismic data.
I don't expect to place competitively but I learn a lot from these competitions. I like competitions like this that are connected to physical problems and datasets (though sadly this one is largely simulated), I learn as much about the broader world as I do deep learning. I've always idly wondered how seismology worked, and now I have an excuse to dig into it.
It's also given me a greater appreciation for the "seismology" we perform in our day to day, like knocking on things to see if they're hollow, or (as I learned here a while back) the way battitores test the porosity of cheese by knocking on it with hammers.
I am working on an [ONLY EV AI SALES AGENT]. I have a dealer feed. I am focused on Electric cars. Basically you ask the AI agent about your electric car needs and using our inventory feed from our dealer partner ( pilot) we match user to car.
Video demo here. Trying to ship ASAP. I will update my site soon. I do sales and my partner is doing the build.
I'm working on a global roaming[0] AI device for my friend's widow[1]. This is the first week of testing in Mabel's hands (lots of feedback already), and Mabel's first trip abroad with it is next week. Between working on improvements, based on this week's feedback, I'll be writing it up in a blog entry (also to-do: setup blog for [0]).
I'm looking for an open source system that has the following features.
Forum for questions and answers.
A section to upload video tutorials
A way for experts(teacher) can upload their own series of videos.
Basically looking to clone laracasts.
If I can't find one, that is what I'll be working on.
I want to increase my presence on Twitter by posting more, but I don't like going on Twitter. So I created a chrome extension that opens a small text box and I write my post there and send it.
A children's book about creative problem solving and entrepreneurship.
The book is written in the Choose Your Own Adventure style. Readers get to join the protagonist Daphne on a fun, week-long adventure launching her own mini-businesses. Readers help her make smart decisions, solve fun challenges, and learn about money and problem-solving in the process.
The book has been a fun endeavor in both writing the manuscript and code! On the latter, I wrote an exporter for Twinery to Org Mode and an Emacs Org export backend to do the reverse.
I am implementing a baremetal USB device stack in an embedded application and an having a really, really hard time.
The device in question is a decoder for sportive chronometry and uses lots of DSP for detecting and measuring when vehicles pass through the finish line.
Just a small hardware project: I am building a cocktail mixer in an old PC case. I saw something similar at a con over Easter and had to build one myself, it had a tap coming out of the 3.5" bay and the ingredients were inside the pc case.
It uses peristaltic pumps to move the different ingredients to the cup. It is very simple, but still took a couple of days to complete.
In detail it consists of 6 x peristaltic pumps, 3 x L298N motor driver, 3 x PCF8574 io expander and an esp32.
The software for the esp32 is very dumb and I actually coded it correctly before I had all the parts, it just enables and sets the speed for the motors and is attached via USB to a laptop. There a webapp is used to manage ingredients and recipes.
Rebuilding most of my serial literature + newsletter service for fiction writers because I used FaunaDB for both DB and authentication and now they are shutting down by the end of May.
I am working on a PromptLibrary (https://promptlib.prashamhtrivedi.in/) to organise my prompts and make it accessible from multiple clients (Including chatbots (via chrome extensions), CLIs, IDE extensions amongst the few).
I wanted a library to store my own prompts once and retrieve it in multiple locations (i.e. Try something on claude desktop and then once I wrinkle out the edges, load it in Roo code or claude code and use it.) Give some variables to the prompt and creating infinite versions of same prompt by providing the value. Or having the versions of each prompt.
Currently I have the landing page, soon (In max 10 days) I will make it live for everyone to use.
A storytelling/creativity card game. I was struggling for a bit to figure out a mechanic that could make it more fun and I think I am finally making some good progress. If anyone has tabletop simulator and wants to help test, hit me up. Stephen at the domain below.
Right now I’m focused on story development and integrating it with the daily-puzzle system I built last time I was between jobs.
This is a years-long slow-burn side project.
My career moved away from the frontend long ago—this is my first React app, with a Django backend running on AWS Lightsail.
I'm currently working on Academy Referral* (https://academyreferral.com). It's a referral platform for martial arts academies, allowing owners to reward their students for bringing in new members.
I've trained martial arts for a few years, and have always been that person who tries to introduce those close to me to the community. I know a lot of other people do the same.
Now, I don't care that I wasn't rewarded for it, but why not? We have point-based programs for nearly everything. Why not for martial arts as well?
* Have a few academies in the process of testing it out. Still a lot to do, including the demo video that isn't going to load on the main page.
The experience with GitHub can be terribly frustrating when it comes to managing the stream of incoming pull requests. The default inbox and notification systems are not so good, and not flexible. Critic allows to create any number of sections, each section being defined by an arbitrary search query.
I would now like to expand it to provide a better code review experience, similar to what Graphite or Reviewable may provide - but under as an open source project. Source code is available at: https://github.com/pvcnt/critic
I realized after trying multiple tools like Supabase and Firebase, I really need to program my own solution. I don't need a bunch of *Enterprise* level features. I just need to read the card data from a database, and process the games with some simple server side code.
I hope to have the server, along with a basic front end done by this summer. Then it'll be released under a permissible license. Probably MIT.
I want a community of different front ends compatible with the same server. I suspect a straight up cli client without a bunch of effects might be popular with some of y'all.
If you want to code a frontend in Unreal, the server doesn't care. The game remains the same.
Of course your free to fork it privately, build a commerical product, etc.
I'm building an MVP for an "AI bedtime stories" app. The idea is that you just input the character names, a theme, and choose a voice (including the option to clone a parent's voice for narration). It generates a story and reads it out using TTS.
There are already a few services like this, but most don't support using a parent's voice, and very few can connect stories together into a continuous narrative based on previous ones.
Also I would like to hold context for fairy tales kinda local. For example Polish folklore is different than British. Most common villains are different and it can be fun and educating problem to solve.
I'm mainly doing this as a learning project, but curious to see where it ends up.
I've been writing a software synthesizer, I want to use it to make an album when it's finished. As of now I've implemented a basic subtractive synth with the usual primitive oscillators, random noise, high and low pass filters, and an ADSR envelope. I've implemented input and output "drivers" for Windows and Linux: WASAPI, ALSA, Windows Raw Input, and evdev.
Soon I'll start work on Lua bindings. The idea is to configure the core engine programmatically. Hook up inputs, modify synth parameters, route output. It's going to be inferior in every way to something like SuperCollider, but I just think it'll be insanely cool to materialize music from thin air. I've learned lots.
I spent the weekend working on the Ansible automation needed to deploy Tomcat and Roller Weblogger for my new personal website/blog[1]. Once the loose ends are tied up with this, I plan to deactivate my Facebook account and mainly focus on the personal site + Fediverse sites for sharing stuff. This is both to be consistent with my principles, which say to disfavor closed-source / walled-garden sites like Facebook, and because it should free up some time I waste when I allow myself to get pulled into political discussions on FB. It'll probably be better for my mental health as well.
I’m working on Catchcam - https://hackaday.io/project/199220-catchcam-speed-camera-det..., a privacy-first, offline speed camera detector for drivers. Unlike apps like Waze or Radarbot, Catchcam doesn’t track your location or require an internet connection. Just plug it into your USB socket, and you’re good to go.
Key features:
• Built-in speaker and LED for alerts
• Preloaded with 66,000+ known speed camera locations (more to come)
• Easy updates via drag-and-drop on your PC
It’s been a fun project to build, and I’m excited to see it help drivers stay away from speeding tickets while keeping their data private.
A custom Python/Django based mini-app (mini — at least for now) that will allow me to import transactions sanely and safely to my local GnuCash install.
I’ve been doing tedious manual entry for a bit over two years now and after having missed three consecutive months, the only other option was to bail.
As a start it should help with 3 main things:
- Translation, categorization: my source documents aren’t in English but my GnuCash entries are. This is one of the reasons I don’t use the built-in imports. (This should shave off at least 90% of time spent entering data)
- Human-error prevention: there were at least 5 times where it took me over 15 minutes to reconcile a discrepancy because I entered some number or some account wrong somewhere.
Working on redesigning my SaaS template. It uses Dokploy to deploy the NodeJS app, and Pocketbase instance within the same server, so DB reads and writes are very fast. Also doesn't use the Pocketbase client library at all, all calls are wrapped in their own API routes and everything is server side rendered.
You might ask why use Pocketbase at all, and I'm not sure anymore. I suppose the dashboard is great, built in auth is great (although I've had to write cookie middleware to make it SSR anyway). I wish there was a lightweight Pocketbase/Supabase style "backend in a box" setup that didn't push the whole client library directly communicating to DB paradigm.
I shared this last month as well but I’ve added a couple new features since then: a weekly digest email, a list of what you’re tracking and a price history chart.
I’ve been building https://lowlow.bot, it tracks price changes on any website. I was inspired by https://camelcamelcamel.com, but wanted something that worked for more than just Amazon.
It’s been handy for big purchases I’m ok waiting for and stocking up on recurring non-perishable essentials when they go on sale. It also lets me know when something has come back in stock.
I’m making a presentation ai assistant. Existing ones don’t cut it… they’re really nice to demo but not good enough for professional use. Full MVP by next week. https://unblank.ai
I have been working with a small team on a platform that allows luxury brokers to do due diligence on clients, ownership transfer and receive/issue payment all in one platform. We are pretty much merging the luxury retail market with banking.
Brokers (cars, planes, houses, boats, watches, etc) never have to worry about chargebacks, they get instant payment, free deposits and payment (compared to payment processors and marketplaces charging 2-10% per transaction).
We are currently onboarding luxury buyers, brokers, and brands you can check us out and apply to be part of the ecosystem. https://nezzapp.com
Working out some smaller bugs of my meta tags checker / builder HeyMeta, which I've rebuilt in Svelte (prevously used Node.js for both FE and BE and it was buggy as hell)
Also revisited and updated Let's see, an eye trainer, which is basically a PWA you can "install" on your tablet/mobile/e-reader. I'm not a scientist, but have had some success training my eyes with this technique and wanted to make a simple app that I can share with my friends to try.
I'm making some minor changes to my personal site/blog to improve contrast, have a more uniform usage of colours throughout, and also replacing "categories" with tags so that I can have related content easily linked and searchable.
I may also finally finish implementing WebMentions support too as a kind of comment section.
I may also work some more on my long-term relaxation/creative maze generation and solver project.
At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.
It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.
To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.
Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".
The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.
So I guess what I'm saying is I've been casually looking around at jobs this month.
This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.
I'm still mulling how to go about porting my tiling window manager for Windows[1] to another platform, or even if I'll do it at all. There is some demand, but I don't know if there is _enough_ demand
Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so
Currently just test driving it in some relatively simple work scenarios, but I imagine it could be a useful tool for consuming a NATS firehose of messages in a single application and routing them internally using the same semantics subject rules so that it would be easy to split them out as separate consumers when/if that became necessary.
RedwoodSDK is a React Framework for Cloudflare. We wanted to build something that allows people to focus on the software that they want to write, rather than the infrastructure that it runs on. Writing software isn't really a barrier anymore, the parts that developers find annoying can be shortcut with generated code, but you can't gloss over pushing to production.
Cloudflare gives us the ability to offer developers compute, database, storage, queues, AI, realtime with durable objects, etc... and to emulate that locally with just a single package installation.
Thank you! Yes, I'm from Nigeria. I became interested in this when I met people from other West African countries and learned that they speak the same type pidgin with tiny variations.
I appreciate you enjoying the game! I work for IPinfo but initially made it as a sort of meme for our users.
I'm generating random IP addresses on the frontend, then making an call to our free API to validate the "realness" of the IP addresses — mainly to remove bogon IP addresses, non-routable IPs, and IPs from large ASNs (national ISPs, the DoD, car companies, etc.).
Our free API supports 1,000 requests per day from unique IP addresses, so there shouldn't be any issues for low usage. However, if we get more power users who enjoy the game, I’ll switch to our Lite API service (which is also free, https://ipinfo.io/lite) to validate IP addresses, as it supports unlimited requests.
Let me know if you have any feedback for me :) I made it mostly by "vibe coding", I will write a post about the whole process of it.
I work for IPinfo — I described my process of how I made the game in the other comment.
Using a dataset-based implementation would require me to have a backend, which is out of the scope of this project. Right now, I'm generating random IPv4 addresses, but if I were generating random IPv6 addresses, I would have to go the database route. For that, I would use our free IPinfo Lite dataset: https://ipinfo.io/lite
My colleagues actually developed an extremely fast algorithm to select truly random IPv6 IPs from a series of CIDRs, which is what you see reflected in our dataset.
Let me know if you have any feedback or suggestions for me, please.
I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the tool will run everything in parallel while caching as much as possible.
If you are a small to mid-sized team, moving to Bazel is massively painful and basically requires up to one full-time position to provide your team with a good experience.
Grog on the other hand let's you keep your existing build setup while just parallelizing and caching it. It's not a full replacement, but it's more than enough for most mid-sized teams that want to have fast mono-repo builds.
Working on a web app builder that generates code via AI, much like hundreds of other tools out there. The differentiator is that the tool automatically sets up a Postgres DB (using Neon) for you. So, it's a lot easier to get started and it can handle large complex apps that require auth and database, but it can also build simple websites. The stack is next.js and code is easy to export and view.
Primarily uses Claude Sonnet 3.7 and Gemini Pro 2.5. But you can choose other models too.
It's an website who's goal is to make it easier to find apartments/hotels/etc that fit your housing preferences (starting with places that are close to the people and things you care about). It's flagship feature is the ability to make heatmaps of cities based on your preferences.
Since February I've slowed down on feature development temporarily as I try and find a way to sustainably increase it's popularity and learn what's the most important thing to focus on next.
Slowly building an open-source Data Lakehouse management utility application for local development, scratching my own itch and trying to accelerate development workflows with customers developing for Databricks.
For now it only supports Delta Lake (using delta-rs + duckdb), only supports table metadata inspection and querying, but in the near future will add dashboards as code, simple Markdown notebook like mode, and Apache Iceberg support.
For now it's an enabler for me and others, hopefully I can turn it into a product somehow at some point.
I am working on a direct competitor to Netsuite. I’ve worked on ERPs, accounting, and inventory long enough to think I can do it. And with AI I can make progress on this in a way that would have been unfathomable a year ago.
RSS readers show content based on the feed they're coming from, and show read and unread items in the same list. That makes it difficult to know which items you've already seen, and is especially annoying for managing items that you want to read at some point but not anytime soon.
Lighthouse splits it into Inbox (new items) and Library (bookmarked items). This makes it possible to process new items quickly, and take your time with reading them.
For a more data science-y project, I'm having a blast building https://nhlforecasts.com. I live in a town with a hockey team, and figured the best way to become a fan would be to understand the sport from a data driven approach.
I did a ton of work on building an Elo model first, but was getting very compressed results in terms of postseason predictions. I swapped to a Bayesian approach which has really taken off. Not sure how it's going to handle the second round of games approaching, but that's a problem for the future!
I'm working on Proflect — a personal and professional growth platform that connects goals, journaling, and feedback into one flow. To help you grow by reflection, not just action.
The idea is that growth becomes a lot more intentional when you can reflect daily, set goals clearly, and get structured input from people you trust — all in one place instead of scattered across different tools.
I'm getting ready to open early access soon. Curious if others have tried combining these areas or if you use separate tools for goals, journaling, and feedback!
I wrote this tool to make instrumenting language servers very easy. MCP (both protocol and architecture) seems heavily inspired by LSP which made me curious about what it would take to support it through my telemetry-capturing proxy.
Haven't thought too deeply about how useful an MCP proxy can be but I see it as potentially a general platform for monitoring or debugging MCP servers or clients.
Yup exactly. My tool is supposed to sit between MCP clients and servers. For now only stdio is in scope. Your tool is great. An MCP server for LSPs! I'll be taking it for a spin.
Schematic and PCB design relating to Lighting and Control Systems for my main job. Schematics and PCB Design after hours as a contractor too, because I have a daughter now, my wife can't work, and life has become /very/ expensive in Sydney.
What I'd love to be working on: Try to initiate a high voltage arc through the air to a target device, and modulate it to send "Data over Lightning", like Alyx does in Half-Life 2. It won't work the way it does in the game, but I'd it's an idea I've had for a long time and I'd love to prototype it some day.
I'm working on a mobile app for exploring places with Wikivoyage (https://mapvoyage.app) and a wikitext to structured JSON-tree parser to support that (https://github.com/bcye/structured-wikivoyage-exports) and am finally getting pretty close to a beta version :) I hope to unify the workflow of going back and forth between Wikivoyage, the favourites list on Google Maps and notes into a single app.
I'm working on a workflow automation tool that lets devs write workflows in simple yaml files, and then deploy them to the cloud _or_ on premise. Each workflow is a set of actions and a trigger that can transform data, make api calls, run AI models, or really anything (via docker!). Each step relies on the output of the last step, and the workflow framework is engineering to be declarative, testable, and versioned. Similar to GitHub actions, but for *anything*. Think webhook to slack, email to support ticket, nightly aws backup & restore, mirror a file each night, etc.
We use data from club & sponsor to measure conversion over time.
Our challenge lies in attributing a select group of people who appear in both datasets. Sponsors spend millions on their sponsorship, and they have no idea what comes back.
We also got funded last week & looking for a founding engineer (2nd employee) :)
As a teacher of computer science, I'm working on various free resources for teachers and students, such as a guide to simulating forces and collisions in JavaScript (https://www.mathsuniverse.com/particles) and super simple real-time forms for lessons (https://www.mathsuniverse.com/forms). What brings me joy is seeing that they are actually useful for people other than just me.
It's a PHP application running in Symfony. All the CMS heavy lifting is done in the Bundle, and a minimal amount happens in the actual application side. I have worked hard on what is there, and still have a ton of work to go. Always could use the help.
I'm still developing podcast websites with transcripts[^0] while maintaining a part-time job.
This thread made me realize I've made no progress in acquiring new clients since posting about this 6 months ago. However, my part-time job ends in May, which will allow me to focus exclusively on Fanfare. It's somewhat intimidating, but I'm also looking forward to it; the prospect of resolving this uncertain situation (either through success or failure) feels liberating.
I spent a long time working in manufacturing and struggled to find a piece of software where we could define a process, share instructions and collect data all in one go.
The idea is you can basically turn your process into an interactive flowchart and follow it through. I’m almost code complete on the MVP, moving into distribution mode in a few weeks.
I’d love to hear from any HNers who’ve gone from 0 to 1 on a SaaS for non technical users. What worked for you?

TUI browser for the Modern Web. Runs JavaScript, works everywhere, but only shows text. Quietude, noise cancellation for content. Sneak peak: https://youtu.be/rmykR_OLYhg
I also just today made a fun way to fully host a front end and SQLite back-end on GitHub for free using Pages + Actions, you can try it right now: https://do-say-go.github.io/fully-hosted/
ShippentPlanner - easily plan and organize your sku paletizing! Make a shippment to a destination warehouse in minutes! For ecommerce sellers. I'm preparing a demo to be able to show to others...
Robot walking. But really, a programming language and tools to make it easy to solve hard nonlinear control problems like walking. There are videos & source code for 2-legged walking robots (in simulation) at https://throbol.com/post/how-to-walk, and videos & source code for 4-legged walking robots (on real hardware) at https://throbol.com/
A minimalist, text-based memory system designed to naturally store and recall important events. It emphasizes simplicity, portability, and human-friendly structure by using six optional fields: who, what, when, where, how, and thing. These fields capture factual context clearly, deferring interpretation for later use or analysis.
Om working om a distributed erp system. The goal being native ui in android, iOS, Mac OS, web, windows, Linux and curses with crazy fast response times. No user operation takes longer than 100 ms.
For the last months I've been working primarily on building a UI framework for Go in Go via WebASM.
Had to implement the bindings first, because js.Value kind of sucks. Meanwhile I am building web components and widgets and it's slowly getting where I want it to be.
Maybe after a couple more weeks I can finally build apps in 100% Go and together with webview/webview. Still needs a lot of work around the edges here and there.
Writing well is hard and takes time. Was it Mark Twain that said "If I had more time, I would have written a shorter letter."? I can totally relate to that this month. Getting your point across without being long winded is challenging.
I'm building a simple web-based drawing app for home sewing patterns. It's a little bit CAD and a little bit sketching tool. Born of my desire for easier and 100x cheaper home drafting tools. The app is still quite early (adding Bezier tools today) and the core workflow is not functional: of draft, lay out, print, repeat, only draft is working. But one step at a time! https://github.com/twaldorf/flatland-client
Working on writing a series of blog posts on interaction nets. The first one is up already an is an introduction to the topic [0]. I feel like the topic is very accessible but the ideas are spread out across discord channels, papers, twitter, and GitHub repos. Hoping to centralize it a bit.
Since my third year in medical school, I've built the largest medical education platform in MENAP. 90k+ users, 100m+ questions solved, billions of seconds spent learning across our Super App. Now working on sustainably scaling further, building medGPT.
It's awesome, exciting and impactful work. I am the first medical doctor + full stack technologist in Pakistan (250m) people, and we've helped the country move medical education decades forward.
Part of my vision is to also help revolutionize adjacent healthcare fields, as we're focused on premed, medical and dental currently for undergrads + recent medical graduates, but nursing, pharmacy, physiotherapy and veterinary school all are of great interest to me. I am a big animal lover personally.
For such markets, you can imagine that the TAM etc is smaller, but still important. For us it's a blend of mission driven and business.
Thanks for the comment! I would love to chat vet-ed-tech further, I am on LinkedIn (/in/az1b) or email: azib [at] az1b [dot] com
Setting up new projects shouldn’t be a chore. We built DevExp (dx) to fix it.
-Secrets stay local (or sync across devices).
-Tunnels with unlimited subdomains + WebSocket support.
-Full HTTP/WebSocket traffic inspector.
-Git profiles per project — no more editing .gitconfig.
-Instant deploys to lightweight Deno isolates.
Coming soon: embedded DB, password manager, dotfile manager, boilerplate generator — all inside the CLI. waitlist: https://devexp.pro
It is a smaller part of a whole collection of addons I've been working on meant for helping with animating character assets from Daz Studio in Blender and then bringing the animation back into Daz Studio.
Eventually I want to have a zero effort way to get characters from Daz Studio into Unreal or Godot with FACS morphs, JCMs, etc. already setup.
I find tracking movies and series I have watched with my partner an impossible task. Spreadsheets are too fiddly for my partner, and I want to look up what is next on my phone so I have turned to Airtable and n8n for automation.
input a relevant url, it will decide if it IMDB or Youtube or a list.
using an llm, it will attempt to extract the movies or series from the list and find the relevant IMDB link.
Then I have a masonry view of movies & series I have and have not watched, sortable by tags that I can rate and add notes to.
I’m working on a review website for Generative AI. Targeted at people who want to use GenAI to build stuff.
e.g.: Following up on one of my HN comments on OpenAI ImageGen gpt-image-1 quality: Side by side comparison of more challenging prompts at Low/Medium/High:
I'm making a hymn presentation website for my dad. He's an organist at the local church and they've got TV's at the front showing everyone the words to the hymns. He switches the pages using a foot pedal while he plays and sings.
The software he currently uses is too complicated and he gets lost easily with all the buttons and features. My website is basically the same thing but only the buttons he needs, only his hymns and is completely controlled by me so I can fix things to suite him.
I updated the catalogue of movies and added some internal tools to my movies released on YouTube website: We Love Free Movies (https://welovefreemovies.com/). It's hard to share it because it gets flagged because of the name... But yeah, planning to add search, design touch ups, more movies, etc. this year.
Also working out the logistics of offering a microgrant to award people who want to make movies like this!
It gives you a ranked list so you can quickly spot the strongest candidates, or at least get a solid starting point without reading every resume manually.
It scores applicants based on job requirements, flags any concerns, and suggests interview questions you might want to ask.
I'm working on a multicast dns implementation in OCaml. It's a library allowing one to build custom queries/responders, plus a conventional querier that can be used as a stub resolver for .local to get the resolver functionality of avahi.
My main motivation was to implement a service that publishes the addresses of containers and vms that I run on my workstation to my local network, but it gradually has grown into a full-blown implementation of RFC 6762, which has been fun.
After struggling with bloated, ad-filled debugging tools, I decided to build MyDebugTools—an open-source, clean, and ad-free debugging tool. It’s designed to simplify the debugging process and help developers stay focused. No ads, no distractions—just efficient debugging. You can check it out at mydebugtools.com, and I’d really appreciate your feedback or suggestions!
I'm working on some social media analysis tools for Bluesky. It's unbelievable that there's an active social network for which you can see all the data.
A simple LLM client, for the simple reason that the one I bought stopped being supported and I could not find any replacement.
It's free, right now only for Mac (Windows coming soon when Microsoft finally decides to approve my account).
You just need an api key from your favorite LLM provider (right now it supports Gemini, OpenAI, Deepseek, and Anthropic).

I am working on Scharf, an open-source SAST tool to identify and auto-fix 3P GitHub actions those are prone to supply-chain attacks. It is blazing fast and written in Go.
I work a lot with smaller investors, in real estate, private money lending, etc. It's sometimes hard to do due diligence on someone, and after having a couple bad deals and realize over 30 people were scammed, I wished there was a simple review site where you could see someone's past reviews.
Site is 80% there, hoping to enter beta in the next month.
Basically a test of putting guard rails around format and content of a website and seeing how much I could automatically generate on a topic of interest to myself.
Biggest benefit I've seen with cursor is to write tests for everything. Far too mcuh content hallucination, or made up links at first, but once you put in some test guardrails you can minimise this.
My wife and I are fans, but their Finland-Swedish Vörå dialect is not easy to understand, especially for us in the very south of Sweden. I have watched the recording too many times to count, and made these so she could enjoy it more.
Still working on Connet[1] and the associated Connet.dev[2], which is a p2p reverse proxy with NAT traversal (and hosted version of it). Currently, adding support for defining multiple points of ingress, next will be adding support for PCP port forwarding.
Aside from my main project, ʻŌlelo Honua, I'm working on an air/hydro foil simulation (just for fun). Currently using rudimentary physics and in it's early stages. Would like to add more particles and incorporate Navier-Stokes equations.
It's attempting to be the easiest and nicest way to monitor Linux servers. I'm currently implementing 0 config custom alerting. All you will have to do is write a file to a home directory with some json in it e.g event_name:blah,interval:1m,data=10 - no server side config at all!
So should be quite suitable for big deployments :)
It is an interesting discovery journey on extracting relevant information from both code and documentation with a sufficient density to stay within the context window and extracting efficient criteria from arbitrarily phrased questions.
I'm working on a motion capture app. The idea is that I can map my movement that's recorded through webcam footage into the movement of a 3d model. This project has involved 3d graphics and AI through 2d pose estimation and 2d to 3d pose lifitng. This project's been pretty fun so far. Here's the github link:
I am working on an open-source insurance application platform.
The main goal is to accelarate time-to-market for insurance and insurtech innovations, providing all these "boring" enterprise features (like multitenancy, role-based security, audit trails, etc.) out of the box, so that you can focus on building the actual product.
I’m working on https://dropbag.co (fyi, not optimized for mobile web yet)
It’s a service for endurance athletes to configure nutrition packs to be available along the course at aid stations.
Right now it’s just a cool tool to build the bags based on your nutrition goals. I’m still doing a lot of outreach to race directors to get an opportunity to pilot the distribution of bags at an event.
I'm about to wrap up the alpha release of an Rust/Tauri based GUI desktop app that allows me (and others if interested) build modular AI agents. At this point it gives you control over the system prompt, LLM, message and which MCP tooling you want to use (to prevent cluttering the request with 69 unnecessary tools you do not need anyway). You can store agents as templates, so you can reuse them with ease.
I'm building Meteor (https://browse.dev) - an agentic browser.
The goal is to remove the prompting layer in CUA, and to have a browser that just gets you and can do actions like a personal assistant.
I got tired of waiting for Perplexity to launch Comet, so me and a friend just decided to build our own. This is probably the most fun I have had building a project.
Open, secure personal genomics using fully homomorphic encryption.
With 23andMe bankrupt, I want to put out somewhere secure people can put their genomic data and receive insights. In a few months, I'll have a protocol in place to open up the data to third party apps (with user consent). The data does not have to be decrypted ever to be operated upon!
I'm working on making Anubis way less aggressive so that it only challenges the worst of the bad bots. I found a pattern that the bots can't fake client side and I've turned that into a sample rule that I've deployed to my website.
It's pretty clear that compute and energy are going to be two of the most important resources to track and manage in the coming decades. I'm trying to get a sense for prices and usage of compute and this project is my attempt to do that hopefully providing useful info to others as well.
I've been meaning to build a Stripe app to experiment with their UI SDK, which allows you to extend the Stripe dashboard interface with custom code. I took a go at it with a Customer Enrichment app: https://marketplace.stripe.com/apps/hybound-enrichment and got a couple of installs!
I've been working hard on MCP Router. MCP Router is a free desktop app (Windows/Mac) that lets you securely manage local or remote MCP servers via GUI, with access control & logs.
I’m working on supporting photo posts on my blog (Kirby), I bought a new camera and thought it would be nice to share them in one place (Cross post to Mastodon).
I’m still looking for a new SaaS idea, so if you have something you want to partner on do reach out. Preferably Rails or Go. Previously I built stuff like https://getbirdfeeder.com/
Exploring MCP (model context protocol) using Claude as a base LLM. I understand that this is quite new and may change a lot in the next few months but I feel something interesting could be done by plugging transactional APIs to a LLM. Remind me of the old CGI (common interface gateway) stuff in the 1990s.
This kind of hack can lead LLMs to be the 21st century browsers.
Oh yes... also working on preparing my retirement end of this year...
ProductMe App: A Duolingo-like app for learning product management theory. It's for people who don’t want to spend thousands on PM bootcamps or courses, but still want quality learning material
It’s free to use with a reasonable daily limit (5 lessons). To access unlimited learning and additional utility features, it's ~$4.99/month
I build right now 7 birdhouses. Using Wood and 3D printed PETG. Each house is a different Build. On computer side I implement a CPU in Verilog for a FPGA for fun. For Bussines I build the firmware for a LCD monitor that can display up to 16 video inputs. It can scale, cut, rotate and distort every input and then place them on different layers. The device is used in telemedicine
I am aiming to contribute meaningfully to the postgres project, to learn and grow as a Postgres hacker, I want to hear directly from you—PostgreSQL users—about the problems you face, big or small.
I’ve been working on https://ulry.app - a simple link archiver that lets you tag and attach notes on each URL. Right now I’m working on a feature that uses LLMs to summarize an article.
Sounds basic, and it is, but I've yet to find any open source project (let alone product) that does this.
All I want to tap a button, talk to the little guy about how to update my document, and see the changes flow. I guess Claude projects or similar might do this but I'm making it more for friends and family. Current use case is keeping track of a house renovation project going on.
I'm working on an internal office project: an AI assistant that connects with project management tools, Google Sheets, and shipment tracking apps. It helps teams manage orders, track production statuses, pull real-time updates, and summarize next steps — all without switching between different systems.
Goal is to streamline operations and make project and logistics tracking a lot faster.
Mostly just exams this month haha, but technically a self-hostable workout tracking app.
The only self-hosted option I found was wger.de and while it looks great, it's a bit too much for my needs. I want something lightweight (so as not to hog resources on my cheap VPS) that does what it needs to do and nothing more.
It's been a while since I've done web dev, so I'm going to try out Deno (TypeScript) with htmx.
Quick project practicing working with some AI tools (Replit, etc) - https://www.tasktiley.com/ which is a task manager focused on building good habits. I was missing a year-long view of what had been completed (similar to what GitHub does for developers) so implemented a contribution graph for tasks.
I recently spent a week building a pricing experiment to test whether moving OnlineOrNot from feature based pricing (upgrade to a higher tier for more features) to pure usage (all features enabled, additional monitors cost money).
Not your regular "idea" but still interested in how it plays out.
I keep adding new features to my hobby project at https://nobsutils.com
It's a collection of various tools that run locally in your browser.
The latest addition is a simple color palette maker https://nobsutils.com/colors
Working on a python library for combining shell commands and python functions with pipeline operator syntax. Hasn't progressed beyond an experimental prototype, some of the tests (i.e. test_bash_pipe.py) show how it works.
In little bits of free time I get here and there, I've been working on using reinforcement learning to build some better bots for my favorite multiplayer game. Project is up here: https://github.com/cgadski/autotude
So far all my work has gone into the technical side of setting up the game (a Java app written in 2010) to work as a reinforcement learning environment. The developers were nice enough to maintain the source and open it to the community, so I patched the client/server to be controllable through protobuf messages. So far, I can:
- Record games between humans. I also wrote a kind of janky replay viewer [1] that probably only makes sense to people who play the game already. (Before, the game didn't have any recording feature.)
- Define bots with pytorch/python and run them in offline training mode. (The game runs relatively quickly, like 8 gameplay minutes / realtime second.)
- Run my python-defined bots online versus human players. (Just managed to get this working today.)
It took a bunch of messing around with the Java source to get this far, and I haven't even really started on the reinforcement learning part yet. Hopefully I can start on that soon.
This game (https://planeball.com) is really unique, and I'm excited to produce a reinforcement learning environment that other people can play with easily. Thinking about how you might build bots for this game was one of the problems that made me interested in artificial intelligence 8 years ago. The controls/mechanics are pretty simple and it's relatively easy to make bots that beat new players---basically just don't crash into obstacles, don't stall out, conserve your energy, and shoot when you will deal damage---but good human players do a lot of complicated intuitive decision-making.
[1] http://altistats.com/viewer/?f=4b020f28-af0b-4aa0-96be-a73f0... (Press h for help on controls. Planes will "jump around" when they're not close to the objective---the server sends limited information on planes that are outside the field of vision of the client, but my recording viewer displays the whole map.)
OkNext! (https://oknext.io) - a task manager for solopreneurs and small teams.
I'd love for you to try it out! It is browser based only for now and pretty basic. I'm adding features sparingly as needed but my next task is to add some documentation for brand new users and making what it can already do more obvious.
Working on a reverse proxy in Rust, https://rpdm.geneseesoftwarellc.com (NYS property lookup), a 3D physics and rendering engine using Entity-Component-System architecture, a time logging application for our clients at work, and another C program for low level graphics stuff.
I have small solo project that I am slowly expanding on. It started as an old-fashioned text sentiment analysis more for my amusement more than anything else ( no real insights were gleamed so original version was used as a foundation for what came next ). I don't think I will ever put it out there publicly, but it keeps me occupied when I need a distraction.
The world didn’t have enough json variants. I’m doing my part and inventing a new data interchange format. Don’t worry though, it’s not compatible with any of the others.
Edit: in case this sounds like a piss take, I’m serious about it. My way is really better though! No syntax typing, efficient encoding, human writable. But also not like the other formats with those properties.
Trying to use genetic algorithms to evolve voice styletts2 tensors for kokoro. Using Resemblyzer as part of fitness calculations. Results have been interesting with over fitting occuring where the voice sounds horrendous but scores high (usually later generations). The funnest part has been exploring how it all works and finally committing to a Python project.
I'm working on email. Principles are growing stronger and for some reason I don't want to use Gmail/Tuta/Proton anymore, so I'm _making my own_. It'll be paid and you'll be able to bring your own domain and however many aliases/inboxes you need.
It'll eventually be at c3n.ro and will be "sovereignly" hosted in the EU.
I'm on a schema migration tool for tortoise-orm. tortoise-orm is a mature async ORM but it lacks a good migration tool. It isn't a super exciting project but it is something that people request over and over again.
I'm building a simple, minimalistic web-based note-taking app called tonotes.com. https://tonotes.com
It's still a work in progress, but it's already functional if you want to try it out. I'm keeping it super lightweight, clean, and focused just on writing without the usual bloat.
Recently I was fortunate to join a cool startup (as Head of Engineering) that tries to improve the AEC industry by helping them with their paperwork.
So lots of RAG, chat, agents, deep research.
It's really interesting but also challenging. The biggest challenges are: large data; different stakeholders/user stories in one org
I'm working on an open-source Pivotal Tracker. I just started a week ago but if anyone is interested in following please checkout the repo: https://github.com/bendangelo/Iterator
I'll have a working project in about a month. But for now it's just a readme.
A bit of a mix between Pokemon Go, Tripadvisor/Wikivoyage and Duolingo.
Basiclaly an app where you can travel a city on a hex grid (h3) and learn about it/receive recommendations on things to do. Different activities and landmarks are hooked into language learning games, which when completed, add phrases/words to a flashcard deck for future study.
I am working on DevOps AI for my DollarDeploy platform. Helps you define correct settings when deploying any kind of app, guessing from the GitHub repo contents. Not another chatbot but Cursor IDE style autocomplete for the app configuration.
For now it is a bunch of ifs, and that's ok - lot of them are generated with AI but validated to be reasonable.
A tool to address friction in B2B interactions (mostly between large companies) I've seen in my career. Main innovations are in comms and contract management. Leaning in on some hardcore dev talent in the team for the stack: there's Rust and Gemini in the mix. I'd say we're past the halfway point of MVP development
I have working on a pluggable secret and key scanner from scratch [1]
The idea is to build scanning databases, file systems, buckets, etc. for static keys and credentials while allowing users to add new file types and parsers.
A website that extracts useful images from youtube videos. It would be a summary but includes the images because "text only" doesn't work for really new ideas. and
"text only" doesn't show bar graphs. And I think I will make it also make it draw boxes and arrows on top of the images for extra clarity.
I made an online partition calculator for ESP32. I made it because calculating this manually is a huge pain, and the only tool I could find was google-sheet based. I've gotten some feedback from people who've found it useful.
Honestly a little bit hesitant to say anything yet. There are a few more features to add, and a whole lot more work to be done to showcase just how cool it is. But the short version is, I'm working on a sort of meta-pico8, a game maker for WebGL2 2d pixel art games (e.g. 320x180 games like Animal Well) that runs in the browser, but one that's firstly collaborative, so that we can all build it together. And some of the coolest features are the based around that. For example, I got arbitrary imports of user code working in the browser, so all you have to do is create an account, add a JS file, and other people can import it as if it were a built-in module, and it just works. Plus the SDK I ended up making is simple, and the API is clean, and there's a few innovations in the GUI layer that I'm excited to share. I wish I could explain just how cool this is.
Interesting, I have been working on a similar project, albeit 320x240.
I also got some code-share and collaboration features working, but got a bit stuck on fonts. But I can appreciate your feeling of 'how cool this is'
I ground to a halt once I realised I had no barrier to entry, ie it could be cloned very easily. Always an issue with Web Development I guess. Plus I hate what modern browsers have become in recent years and not sure I want to target such a fast moving platform. I got burned once already with WebStart 'warning this app might do something scary' and certificate fiasco.
I thought about some native binaries, but I know I am kidding myself. I had an ios app that was pixel cloned within 6 months. But somehow a web app feels like publishing straight into public domain.
It's not just the web, native apps have always had free open source clones that technically render them useless, often just as good quality, yet they didn't go out of business. There are other considerations people make when deciding to use an app, including network effect, a strong community, sheer level of quality and passion from the developers, etc.
For fonts, I just went with a simple raster bitmap font and pixel grid storage format. Creating these limitations makes it easier for me and for developers and artists. I choose 320x180 because it fits the 16:9 perfectly, which would make full screen ideal on most monitors.
A prompt collection platform that let's you organize your prompts, share them, learn prompts from other users and reuse them on multiple LLM / AI platforms.
It's aimed at improving prompt engineering skills for both technical and non technical LLM users.
Currently in Alpha phase and actively looking for feedback.
I have too many podcasts to listen to and realistically not enough time to get through all of them, so I created a web app that transcribes and summarizes your podcasts and emails you a summary every morning.
My current side project is a vulnerability scanner for binaries. I do VR in my day job, so im trying to figure out how useful (or not) AI is for this domain.
Jury is still out. Getting false positives and negatives, but I can find some known CVEs!
Very early stage, no link, but I have been working on getting terminal fonts (like Cascadia Code) to work in the browser more progressively without requiring such a giant single download, and on using them for text-based animations. One of those unimportant, low-stakes kind of projects that makes it relaxing to work on :P.
Building a AI-assisted aviation regulation compliance tool for aviation professionals: https://aviation.bot
At the moment just a RAG with EU aviation regulations. Soon FAA, UK CAA, and more complex AI agent features that do more complex deep research.
I've been working on Million Timer (https://milliontimer.com), a time-blocking and invoice generation app for freelancers who hate tracking time but need to do it anyway.
While it's still in alpha phase, please feel free to beta test and roast it.
Checkra, an inline assistant for UX, copy and conversion feedback right on your site. It’s easy to set up with a tiny JS snippet and free to use - no account needed. We’re using it for our in-house product development and it has streamlined our workflow for generating A/B versions of pages and copy significantly
I launched Foqos here a few months back: https://github.com/awaseem/foqos and just working on the feedback. Since then added QR codes, breaks, ability to block apps manually and even a mini redesign. It’s been a ton of fun so far!
I’m working on https://askcrystal.info. We’re a government dataset aggregator in our very early stages. We’re looking to expand into API use cases, e.g. grounding LLM responses. Would love to get feedback and connect with others in the space.
We're building Grovs (https://grovs.io), an alternative to Firebase Dynamic Links, Branch.io, and AppFlyer. It handles dynamic links, attribution tracking, and referral analytics—great for deep linking and marketing—at about 40% of the cost.
Explicit is a validation and documentation library for REST APIs built with Rails that enforces documented types at runtime. This week I added support for MCP servers with the Streamable HTTP transport.
Working on adding Job schedule and cron features in Daestro[1].
About Daestro: Daestro is workload orchestrator that can run compute jobs across cloud providers and on your own compute as well. More like cloud agnostic batch jobs or step functions.
I am a tech guy, now turned VC in Europe. However, something curious and interesting I'm working on with some partners is the renovation of a Palazzo in Venice. Learning new things almost every week. Absolutely stressful, and exhilarating. Completely different from coding or investing in tech startups.
I’m building an accounting automation tool that captures and extracts information received from your billing inboxes and send them to your accounting system. I had this idea after freelancing and running a small software business in Estonia for 4 years. Let me know if you want to become an early adopter!
Taking on a fun technical challenge, building a distributed database to serve the needs of Actor State saves in Orleans. Using the guarantees around actor placement to implement something optimal for its needs.
Much cheaper to hire a VPS with attached local storage, than to use an external database and a lot quicker too.
Building a foot traffic API to see the busiest venues (bars, shops, museums, etc) in (your) worldwide neighborhood: https://besttime.app

I cobbled together something that generates playing cards from html and css. Currently running off a csv, building a game for a friend's birthday.
The experience with printers has left me thinking there's a gap in the market for _good_ Europe-based, small batch card printing. Awful experience with printers.
Working on my university degree. I failed my first one and now I got myself into a critical situation again. Started using Anki. I often put in the hard work of thoroughly understanding a subject but don’t profit off it because I don’t keep the understanding after that. I am working on improving that.
https://visitorquery.com a proxy & VPN detecting tool that does it's thing based on the specifics of a connection rather than parsing list and known databases which makes it very effective against residential ones too.
[1] Surveys. Thinking about how to tighten up the onboarding experience, improve brand awareness, improve in-app data analysis, and how to integrate AI in new and exciting ways... and handling customer support tickets!
I am also working on the last few remaining issues of Hyvector, of which some are surprisingly difficult to solve and AI unfortunately cannot help me a lot.
I work for an asshole, it's been 4 years but i can't find any other job (frontend) i found the job when i was 17. i hate it so much that i don't have any will to code on other things but lately i have been learning more low level programming like c and doing shaders using c.
An email-based service to mail your photos as postcards. As a parent of littles: the littles love the postcards, and the grandparents love them too.
I know you can print photos at Walgreens etc, but I never do it because it has some friction: email-based reduces almost all of the friction in my use case.
I'm working on a distributed object storage system to be the backing store behind my website (https://scmscx.com). It currently uses back blaze b2 which is good and cheap but I thought it would be fun to roll my own.
I’m working on https://vimgolf.ai, to help me learn new vim commands and in doing so hopefully help others. Right now, still working on adding the ai assisted level creation for each motion, but more to come on that.
One suggestion: please consider allowing custom key mappings. I use a Colemak-DH layout, so I remap HJKL and other VIM keys to more ergonomic positions. Tools like Vimium support this, and it’d really help with accessibility for non-QWERTY users.
Is it possible to add an interactive challenge or two on the homepage prior to sign up? I think that would hook people in and make them want to sign up.
Good idea, currently I spin up a 2 neovim instances for each challenge, so can only spin up so many at once with my current setup. But, am moving to a kubernetes setup where I can scale up and down the number of neovim instances more reliably and will add that in then.
I have, but all the JS vim clones are emulations of vim, and don't support all the vim motions (like copying from registers, etc). I honestly could do that and it would be easier, but doing it this way, also allows me to record the keystrokes directly from the neovim runtime.
I'm currently developing qApp, a lightweight queue and appointment reservation management system for businesses (banks, clinics, shops, etc.). The idea is to let customers join a queue through a simple online form and receive updates via SMS — no apps, no complicated logins.
Billing. Subscription plans and invoices in micro services architecture.
I honestly hate it at this point and would appreciate any reading on the topic. It's been a grueling 4 months of back and forth with a lot of mission critical business aspects to handle that I had to learn on the fly.
I was having trouble meeting people after moving to a new city so I designed and printed some goofy funny t-shirts for my wardrobe, and that has really helped on getting the ball rolling on conversations.
Hoping to make the launch within the next few weeks.
What are some examples? I'd love to check out your store but I'm worried by the time you launch this post and any communication with you will have vanished to the ether.
Trying to understand the possibility and feasibility of LLM on Indian vedas and ancient hindu mythology. I am thinking like there is a input box where user will enter his problem,/query and get resolved with the help of Vedas, puran and old hindu religious books.
pile - a framework & cli for managing a large number of docker-compose files running on the same machine.
Inspired by a pile-of-poo SOA application where essentially every service was dependent other services such that the entire app stack needed to be run in order for any 1 service to work.
In addition to organizing the array of docker-compose files, which may live in different directories, i also add some helper functions to bring clarity to the usual docker cli output. Ugly "docker ps" output can be gathered by using pile ports, pile commands, & pile state - all of which output what you think they do, but in a way that is actually legible and useful when running 20+ containers locally.
An eBook sever on raspberry pi running nodejs. I had a lot of issues with iCloud not being able to download my books, plus my entire library is almost 1 GB. So, my solution is to serve a list of PDFs over node and allow download of a specific page range.

I am building https://hire.blue, its a platform for HR to reduce time to interview by 90% while being applicant friendly, this can be used as a ATS for small companies and for founders!
Still supporting https://monkeys.zip - my pet art project where users simulate thousands of monkeys on typewriters for silly rewards. After which, moving on to a music creation app.
Working on static website hosting. Thinking about how I can build backend functionality for customers as well while maintaining the openness that the static hosting has offered.
I'm working on an application that will help me install AppImages. The problem I'm solving is that some apps come with the wrong logo/icon. So in the app I'm building we'll be able to set a custom icon for the AppImage.
A merge conflict resolution tool integrated with GitHub. Now working on a solution for preemptive conflict detection and a smarter/simpler merge queue.
Currently I'm developing https://findl.top. Lately I've added sort of an AI-analyst, which can help to find meaningful changes from one financial report to another
on Orchestra, a chat-centered tool that addresses the collaboration gap. it’s when your software drives you crazy with all its complex features and integrations, when all it should really do is help you work. simple as that.
startups and small teams like ours don’t need a monster setup. we just need the basics to communicate and manage (as god intended). a few years back, the three of us – me and two fellow CTOs – got tired of searching for the right tool, so we built one ourselves.
i am building a little iMessage app called Whenish.
this was spurred from group texts with friends planning a vacation or outing. we would just throw a bunch of dates that would get lost in the mix and people would forget who was open on what dates. Whenish just allows user to select dates they are free and then it will show what is the best date that works for everyone.
i have a testflight right now and if anyone wants to give it a go please do! i would love feedback :)
I'm working on a desktop-based, performance- and privacy-first note-taking app that lets you quickly capture notes from any selected text using hotkeys.
I'm curious: what are your must-haves in a note-taking application?
I thought about doing something similar some time ago, because I never quite found the perfect note taking app for myself. There's a million ways how to do notes, and it feels like there's just as many different notes apps.
Eventually, I've settled with Obsidian because of its simplicity and extensibility. You can leave it with basic features and truly own your notes in a simple format (you can also put them into any cloud, as long as that cloud reaches your filesystem). It doesn't do everything just like I'd want to, but I've thought about just building another notes app that reads and writes to the same path your Obsidian notes are in, instead of trying to cover every possible editing feature like most big notes apps. Then I'd use different apps for different needs, with one place to store data.
Since you're focusing on privacy, have you considered using Obsidian? Is there anything particular you want to do differently?
Basically I want to build it with focus on speed and work efficiency from start. To not bias myself too much, I will refrain from doing too much market research. First of all I'm building this for myself, and I'm guessing it might translate into at least a tiny market share.
I’ve been doing a lot of work with ros2 lately at work. Been seeing some moves with VLA models driving robots with text prompts. I think I’m going to focus more of my “free” time on mastering that technology.
I am trying to create an open-source alternative to JustCall and CloudCall. These SaaS products use VoIP as their foundation and provide AI agents for calling, along with multiple features during the call.
PostScript has two mechanisms to save and restore the machine state and they are intertwined and only vaguely documented. I'm trying to get my head around all that this week.
Working on Replyhub.co, AI that finds high-intent posts on Reddit and X where your product can naturally be introduced. It suggests replies, tracks leads, and helps turn conversations into conversions.
In my last week of funemployment before going back to work. I’m working on fun stuff like gardening, designing battle tech terrain in cad and building a web tool for solo roleplaying.
I'm working on platform that helps you vibe code APIs. It'll generate clean, scalable, maintainable monolithic backend APIs built using Express + Postgres.
Launch soon! Drop a comment if you want early access
I work at a secure online elections company. We're refactoring the code to make the tally as performant as possible, both in the use of resources and speed. So this is the fun part :)
I'm still working like crazy on our privacy-friendly web analytics tool Pirsch Analytics (pirsch.io) :) I've been doing this for more than 4 years now and I'm still super motivated, especially because it's challenging from a technical point of view and very rewarding (I live from it now).
There is still a lot to do and learn (especially in the marketing department), but we have plans for a new product in the privacy space. I don't want to say too much about it until we've started working on it, but it's in the compliance space and fits quite well with our existing product. I think it's always a good starting point to solve your own problems.
I am extending my pet project menuop.com, a digital menu maker for restaurants. I plan to integrate AI to enhance visual impact, analytics and recommendations to restaurant owners.
A line haul network optimization engine for international air freight. Managing line haul schedules and freight moves between carriers/cities/terminals etc.
Trying to make interpretability research practical. A bit early for the demo, but I am getting some interesting results for large multimodal models in terms of their reasoning.
Letterboxd for video-games! Don't know if it's novel enough but it's given me the chance to get into front-end design and think harder about database design.
Sourcing a vendor to unravel 2 decades worth of VBA macros that are the backbone of a company so that we can make it more modern and scalable/extensible.
This is something I definitely want to check out. I was playing around with raku just before christmas and wanted to try making a small webapp with it.
Great work, I've been using Stock Events on iOS for a while now. It's what got me into dividend investing, and it's fantastic to just keep track off all the dividend income.
first order zero knowledge proof system (zk-stark), it works on android, macos, linux, webassembly, vulkan/cuda backend (metal coming), but the composition polynomial evaluation is suboptimal so i am working on that now
Notably not an AI agent like Operator, Manus, etc. which are largely unreliable for the time being. Instead this uses AI to turn your task into something repeatable and configurable.
Currently focusing on scraping use cases but hope to make it more powerful soon so it can actually do complex tasks rather than just extracting data.
basically a user give an initial prompt ie "create a game" and then a series of ai (gemini, openai, claude) prompt themselves until a finished outcome. the user can change any output step in between so the end result can be tuned instead at any point
just finished https://www.treesnap.app/ now just doing some light marketing on the daily. next project is multi-vendor monstrosity so happy to have gotten that win.
A sales co pilot that helps startups move deals faster.
You can think of it of Cursor for sales. It knows to perfectly summarise deals activity and prepare the next action. Saving you precious time and enables you to close more customers faster
A tree cutting tool.
Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree.
The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side).
I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping them back to their original state, but in an order that does not intersect other branch vectors.
The idea came to me as a particularly difficult tree needed to come down in my friends yard, and we spent hours planning it out. I've already gotten some interest from the tree-surgeon community, I just need to appify it.
Second rendition will treat the problem more as a physics one than a graph one, with some energy-minimisation methods for solving.
The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it.
You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.
Entirely offline & no usage of AI. Free in-browser version (using PGLite WASM), paid desktop version.

I’m working on Popgot (https://popgot.com), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials.
On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging peanut butter with BPA by checking every photograph of the plastic or avoiding palm oil by reading the nutrition facts) or brand lists (e.g., only showing WSAVA-compliant dog foods). Still reviewing results manually to catch bad extractions.
Started this to replace a spreadsheet I was keeping for bulk purchases. Slowly adding more automation like alerting on price drops or restocking when under a threshold.
I am about to begin a PhD in astronomy. Until last month I was working at Caltech for 3 years on code which calculates orbits of asteroids to high precision. This code is being used on several NASA telescopes now to predict when they will image known asteroids (NEO Surveyor, SphereX, maybe Roman eventually). I was allowed to open source it and I am planning on making it the basis of my PhD research:
https://github.com/dahlend/kete
It can predict the location of the entire catalog of known asteroids to generally within the uncertainty of our knowledge of the orbits. Its core is written in rust, with a python frontend.
https://github.com/colibri-hq/colibri/
Colibri—a self-hostable web application to manage your (and your family's) ebook library, intended as a companion to Calibre. I want it to be a friendly, simple, capable, opinionated app to review your books, add metadata to them, get them onto your reader, share them with family and (few) friends, create a public shelf for bragging, connect with Goodreads etc., and exchange comments and reviews on books.
This is explicitly not intended to ever be monetised, and I enjoy all the implications that has on the design. Colibri is as much a tool I personally want to use, as it is a study in small-audience user interfaces, and the quest to build the perfect book catalog schema.
I'm looking for fellow book-loving people to work on Colibri, to create the best personal digital library possible. If you're interested, feel free to reach out via email (in bio), or on GitHub.
https://mysukari.com - A Diabetes management platform
I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and started working on My Sukari as a platform of free tools for diabetics.
I mostly get time to work on it on the weekends, so it's not yet ready for public use, but I've fully fleshed out one of the main features: Sugar Dashboard - A dashboard that visualises your Glucose data and helps you easier analyse it.
To help with demos, I've shared my Sugar Dashboard here: https://mysukari.com/tools/sugar-dashboard/peter
I'm really passionate about this and getting as much free, practical tools in the hands of patients (it honestly shouldn't be this hard to manage a disease)
So many cool technical projects here. But I am doing something completely different - masonry. Repairing walls in 3 rooms. It includes reinstalling dozens of falling off bricks, installing 30 or so power outlets, replacing old windows with bigger modern ones, fixing openings for the doors and plastering everything afterwards. On one hand it’s interesting, because it’s very different from the dayjob. But doing it by myself pays my newish car in cash immediately. However I wouldn’t do it for money somewhere else, it’s really really hard work.
Instead of masonry I would like to work on time of flight cameras. But the day has only 24 hours :-(
I am working on the sunflower plant density estimation problem. The goal is to be able to estimate the germination rate as early as possible. Farmers benefit from such information, because:
- there are lots of expenses still to be made (fertilizer, pesticide, salaries), which may not be worth it if germination is under certain threshold
- if detected early, there is still time to plant another grain or to fill up the missing plants (requires precision seeders and seeding maps)
- is a very good proxy for yield estimation (farmers often trade futures even before they have harvested)
For the purpose I have created a dataset (a collaboration between my employer and Sofia University) and published it in order to enable scientific collaboration with other interested parties. Still working on the dataset annotations.

Working on a browser extension to make it easier to find content on YouTube that fits your interests.
I watch a lot of YouTube videos and have found it very annoying that YouTube latches onto one or two topics that you've watched and only recommends that type of content over and over again. Even if you use their "Not Interested" tool, not a whole lot changes in your recommendations.
At the end of last year I launched Relevant - a crowdsourcing website where users can categorize the channels they watch into a defined hierarchy of categories ranging from broad topics like "Science" and "Gaming" to more specific ones like "Phone Reviews" or "Speedrunning".
Although I've had good feedback on the website, engagement has been relatively low and I think that's because it's a big ask to have someone navigate to the website to find the content. This year I decided that I'd bring the content to them by making a Chrome extension that lets users interact with Relevant directly from within YouTube.
It's still a work in progress but I'd love to get a first version out within a month or so to start spreading the idea and gathering feedback. If this is of any interest to the people here on HN then please let me know what you'd like to see most on your feeds.

I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+).
In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession
It's niche and boring, but I help immigrants pick German health insurance.
The existing information is mostly blogspam from non-experts who try to make a quick buck. They only recommend the two brands with an affiliate program.
I wrote a better guide with help from competing insurance experts. The information is clear and succinct without oversimplifying things. It addresses the specific needs of immigrants.
Then I turned the advice into an interactive recommendation tool. People get clear, specific advice in a few seconds.
The best advice is "don't choose yourself, talk to a broker". The problem is finding a honest one. It took me years to vet a good one. After testing him for a year, I have set up an affiliate partnership from scratch with him. The partnership incentivises honesty and neutrality, because he has a lot of skin in the game.
I'm super excited about it. I can't overstate how much of an improvement it will be. Readers get far better advice and easy access to an expert. The broker gets a steady stream of well-informed leads. I get a commission for my trouble. It's a win-win-win situation.
I'm almost finished with a project that has taken up quite a lot of my life for the past few years, a book on Estonia! After working for their government and returning to the U.S. I wanted to better understand how the country modernized so effectively after gaining their independence from the Soviet Union so I did a fair amount of research into the topic and many interviews which culminated in a book, Rebooting a Nation.
If you're interested in Estonia, e-government, building tech hubs, and the future of the nation state I'd love if you take a look (and let me know what you think). It's available on Kindle now but Oxford University Press will be shipping out physical copies May 15 and buying from a smaller press is always appreciated!

Myself.
Been a freelance dev for years, now going on "sabbatical" (love that word) imminently. Just moved to reduced hours, still in the transition and unwinding phase.
Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things.
I'm excited.
I hacked my old kindle and turned it into a eink dashboard for my daughter’s school! Now planning to enahace it a bit further and make it easy to customise.
Here’s a a detailed write up of the process: https://samkhawase.com/blog/hacking-kindle/
Reverse typesetting: reflowing page layouts where you don't have knowledge of the typesetting structure, i.e. a scanned physical book or PDF paper. Naive rules-based heuristics based on the dimensions of bounding boxes and gaps. Point is to reflow things for resizing to eink readers. (Specifically the size that fits in my pocket which I carry around. User #1 is me). Building in Common Lisp and targeting an Emacs mode for interactive execution with manual feedback.
A pentagonal geospatial indexing system: https://a5geo.org/
If you’ve used H3 or S2 it should be familiar, the major difference (apart from the fact it uses pentagons) is that the cell areas are practically uniform, whereas alternative systems have a variance of around 2 between the largest and smallest cells, making them less useful for aggregation. The site has many visual demos, e.g. https://a5geo.org/examples/area
The code is open source: https://github.com/felixpalmer/a5
PodSnacks (https://podsnacks.org) — Personalized AI summaries of top podcasts, delivered to your inbox.
I've been building PodSnacks because I found it overwhelming to keep up with podcasts across tech, business, and science. PodSnacks uses LLMs to summarize the most popular episodes from shows like Lex Fridman, Acquired, All-In, Invest Like the Best, and more.
You choose your favorite shows, and we email you short, high-signal summaries — no audio to skim through, no endless backlog guilt.
So far:
126K+ episode summaries generated 92K+ hours of podcasts processed 48–50% open rates 2,900+ early users
Still iterating and adding features like bundling by theme, language translations, and audio feeds.
If you're the kind of person who wants more inputs without more noise — would love for you to check it out.
Always open to feedback from HN!
I've recently re-watched John Carmack's 2004 Quakecon keynote (https://www.youtube.com/watch?time_continue=602&v=OOVUZZr655...), which happened during the Doom 3 launch. In that keynote, he mentions that he didn't see any differences between stencil and shadow maps. He mentions that he experimented a lot with both approaches, before settling for stencil shadows which were much faster.
I got curious about that statement, since shadow maps tend to look much different. I also knew that he left part of the experimental renderer in the GPLed code. So, I've decided to go on that rabbit hole of Doom 3 graphics, specifically Carmack's experimental renderer and ended up implementing his approach, as well as adding some poisson disc sampling and fixed the peter panning: https://github.com/klaussilveira/exp-dhewm3
I also spend a lot of time on archaic game engines. I like to call it software archeology.
I launched my web-based notepad calculator, https://numpad.io/, a few years ago.
Right now I'm working on a version 2 that has user accounts, multiple documents, markdown support, and document exports. Everything is local-first and it uses CRDTs to sync documents.
It looks like this: https://i.imgur.com/Plk1DQ4.png the calculator is mostly the same for now, with a few improvements. It's unstable right now, so I don't want to publicise the dev url, but if you'd like to become a beta tester email me at contact@numpad.io
I just put live a daily logic puzzle, Clues by Sam. I've been working on it for a while now, mainly on the level generator. It was tricky to generate levels that are solvable using logic (no guessing needed), and also fun to solve (no crazy long deduction chains, but also not just obvious things). I'm sure the implementation still has some quirks on some devices, so would love to hear if you encounter issues!

I'm currently working through Frank Sikora's "Jazz Harmony" book [1] to learn to play Jazz piano.
In parallel, I'm building an exercise generator "Jazzln" [2] to help me practice.

Creating stealth group in a huge Fortune 500 company with the blessing of my immediate boss but no other higher-ups. Trying to productize critical consulting tool sets in the utility industry so we can stop repeating ourselves for the 100th consulting engagement.
Yes, customer is a special snowflake but they still need 90% or whatever every other client in this industry needs.
Feeling increasingly like this is a fools errand.
Even though we've proved this out with tool sets strung together with duct tape and safety pins, and are therefore the most profitable group within our department, we still need to be 100% billable.
It's only because we're the most profitable group that we can pretend we're all billable while I work with two other people to bootstrap this crazy project
Edit: anyone hiring? Just found out my boss is quitting.
It tried out vibe coding this weekend. I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.
I hit an OpenSearch bug this week where you can't get any browser based requests to work. Its due to zstd becoming a standard part of Accept-Encoding and OpenSearch not correctly supporting it so I wanted to install a browser plugin that modified the browser HTTP request headers to my servers.
I don't know about everyone else but I love that browser plugins are possible but I hate having to find them. Its mostly due to never knowing if you can trust a plugin and even if you find one, you have to worry about it being bought out in the future. With vibe coding I was able to build a browser extension in 45 minutes that had more features than I originally planned for.
I spend more time documenting the experience than building which is wild. If you are interesting you can look at the README in https://github.com/mattheimer/vibe-headers
But I left the experience with two thoughts.
Even seasoned developers will be using vibe coding in the future.
I think in the near future the browser plugin market will partially collapse because eventually browsers will build extensions themselves on the fly using natural language.
A note taking app - I know, I know, been done a billion times. But really, no software I’ve found works the way I want it to, so I’m just trying to write my own, starting with a front-end agnostic core and a TUI.
If it strikes a chord with anyone, I’d love to collaborate! The concept is centered around organization bubbling up naturally from dumping info in with tags, and “typing” your tags so that when you go to a tag’s page, the layout is customized based on what it is - a project, person, etc. A project could have all relevant tasks and notes listed, whereas a person might have name, contact info, etc.

Working on a database compatibility tool. So your app works on SQL Server 2022 on-prem, but does it work on Azure SQL DB, AWS RDS, GCP CloudSQL, etc?
These cloud flavours have a compatible SQL dialect, but it's often details like missing features (CDC and Auditing on RDS are good examples) or differences in system objects that make it difficult to support your app on these platforms.
I capture all sql statements, run them through multiple SQL parsers to find all the system objects your app is using (tables, functions, stored procedures, etc). I then check them all against a catalog I have built of all system objects for every version of SQL Server on every platform.
I then give a report to see which platforms your app will work on, which ones it wont work on and which system objects are the problem.
Other database engines will be added once I get it working end to end (almost there).
I'm working on a new open source CAD program for 3d printing based on Signed Distance Functions.
Benefits of SDFs over the standard Boundary Representation (used in Freecad and similar) are that you can do "pattern" operations with domain repetition, which means making N copies of a feature is O(1), vs O(N^2), you can deform objects with domain deformation, which means if you have a closed-form representation of how you want to deform space you can basically directly apply that to your object, procedural surface texturing is easy, CSG operations are easy.
The big drawback is that it is hard to provide any workflow based around "selecting" faces, edges, or vertices, because you don't naturally have any representation for these things, they are emergent from the model's SDF.
I have some blog posts on my progress: https://incoherency.co.uk/blog/stories/sdf-thoughts.html and https://incoherency.co.uk/blog/stories/frep-cad-building-blo...
I am solving the "selecting faces" problem by having the SDF propagate surface ids as well as distances. So the result of the evaluation is not just the distance to the nearest point on the surface, but the id of the specific surface that is nearest.
My next big frontier is reliably providing fillets and chamfers between arbitrary surfaces. I have a handful of partial solutions but nothing complete yet.
The most promising idea is one that o3 came up with called "masked clones", the idea is roughly to make a clone of the 2 surfaces you want to blend, mask them by intersecting with an object that is like a "pipe" along the intersection of the 2 surfaces, apply the blend within the pipe, and then add this "blend pipe" as another child of the lowest common ancestor of the 2 blended surfaces.
And after that I need to work on more standard CAD stuff like constraint solving in the 2d sketch editor.
https://undetectag.com I developed a device that turns an Airtag on and off at specific intervals. Current Airtags are detectable right away and cannot be used to track stolen property. That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location. It’s not foolproof, as the timing has to be right, but still useful.
I am working on a super mario land re-implementation for game boy using C. It's made with the GBDK toolkit so the ROM can be run on a gameboy. Currently the scrolling and background collision has been implemented, I am working on drawing the enemies... their is still a long way to go. As for why I am doing this is nostalgia and fulfilled a childhood dream repo at https://github.com/odrevet/marioland-gbdk/
I'm working on an escape room! Initially I was working on a software/hardware bundle that I was planning to market to other escape rooms but I think that is the wrong approach. So I am going to build a bunch of modular stuff in my garage and eventually start my own, its been an awesome project so far! I want a more dynamic and action oriented experience so it might not really be an escape room anymore but I don't know what to call it yet.
Escape rooms are honestly... almost always a let down but the concept has a lot of potential and there are some really neat ones that standout like this local one where you pilot an airship https://www.portlandescaperooms.com/steampunk-airship
Once I build the best escape room on the planet, I can consider selling the tools.
I'm hacking on Trailbound, a hiking and backpacking planning tool. The goal is combining a light version of the routing capability of Caltopo or GaiaGPS with more granular "leg" mapping based on how I learned to plan off trail trips and sharing functions that make it easy for my wife to know where I'm going to be, who I'm with, and who to contact if I'm not back in touch when I said I would be.
Its been a blast to build. At one point I was hosting my own ORS server but that's extremely silly to do when Mapbox has a very generous free tier. Learning about all of the open source tooling and open data available in the mapping world has been incredible.
The cost of the Hetzner box it runs on isn't much more than a Caltopo pro subscription with the added bonus of being much easier to share with non-hikers.
A quick demo: https://www.loom.com/share/a5f7a7c23457400aa92b3f0f71a0008f
The app: https://go.trailboundapp.com
No marketing site, no onboarding, or any real UX attention paid to the app at this point, it is mostly Just For Me and will probably remain that way once I land a job again.
I'm starting to chip away at an iOS app so I can get offline access to maps and routes, but I'm not a Swift dev so the going is slow.
As a follow up to my relatively successful series in x86 Assembly of last year[1], I started making an OS that fits in a bootloader.
I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes.
It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor. It's a lot of fun!
Not quite done with it yet, but you can see the progress here https://github.com/shikaan/OSle and even test it out in the browser https://shikaan.github.io/OSle/

I am working on an app for rhythm training for dancing. The first step is beat detection in music - here is my code for generating videos with beat counting: https://github.com/zby/beat_counter (vibe coding warning). Beat detection seems to work OK, downbeats are a bit more tricky and I have found not good solutions for further structuring of music (for dancing they usually count to 8 - that is two 4 beat measures - or 6 - two 3 beat measures for Waltz for example, I am not sure about 2/2 measures and other). Seeing all the LLMs generating music I thought there should also be LLMs interpreting music - but so far I have found no such model the available algos seem to be from a previous decade.
My current plan is to test the counting with people with good rhythm sense and once I find a good algo for beat detection I'll proceed with writing the app.
We’re building a new social-enabled git collaboration platform on top of Bluesky’s AT Protocol: https://tangled.sh
You can read an intro here: https://blog.tangled.sh/intro (it’s publicly available now, not invite-only).
In short, at the core of Tangled is what we call “knots”; they’re lightweight, headless servers that serve up your git repository, and the contents viewed and collaborated upon via the “app view” at tangled.sh. All social data (issues, comments, PRs, other repo metadata) is stored “on-proto”—in your AT Protocol PDS.
We just shipped our pull requests feature (read more here: https://blog.tangled.sh/pulls) along with interdiffs and format-patch support! https://bsky.app/profile/tangled.sh/post/3lne7a4eb522g
We’ve also got a Discord now: https://chat.tangled.sh — come hang!
I've always been into MUDs since the mid-90s and every now and then I get this idea to write one from scratch (again) and I get pretty far and then I lose interest.
The new one is browser based.
The mud engine runs in a web worker and takes advantage of some of the modern web tricks to do stuff. For instance, data files (think: area files that don't change often) can be stored remotely and then cached with a service worker. This allows the MUD to run offline. But that's only fun if you're playing solo.
IO between the UI and worker is handled by message passing.
Multiplayer is handled by the MUD opening an outbound connection (probably websocket) to a connection collector host. Other players would then connect to that host and have their IO routed appropriately. The host can even be smarter: it could be a specialized Discord client, allowing users to play from there. Firebase may also be involved. I don't know.
The important bit is that this is still basically message passing, so the engine won't need to know the difference between the local user and a remote user.
The MUD database would be an IndexedDB. Probably. I haven't thought as much about that yet.
I am sure all of this is theoretically possible, at least.
Creating a modern development environment for win98. Currently I’m working on a git client. I have no patience for learning C. So backporting git is not an option. I also don’t want to use cygwin. So I’m using a server to expose git as http endpoints and coding a git client in php to use in msdos. I have Vim 7.3 and and gnu coreutils working in msdos already. So soon I will have a very nice dev environment. I want to create a one click installer which gives you xampp, vim and then all the tooling I’ve created. I’m also interested in creating SPA that works in IE5.5. But I’ll do that when my tooling is ready.
I'm building a platform for small-city business directories called TownWire: https://townwire.com
We launched our first location last week and have had a great response so far from business owners and residents alike: https://canandaigua.com With the current tech climate of AI and big tech, things have gotten so impersonal for the majority of actual people. I'm betting on communities and the small businesses that serve those communities in the medium and long term.
I'm working on my second self-published technical book related to Elixir. The first one has been a surprising success, but since it was about learning to use Ecto on the basis of an old pedagogical toy database (and tiny dataset), the new book is about the development of a production-grade REST API with Elixir and Phoenix.
I find that many books out there are focused on documenting the "happy path" for rather small and simplistic applications without boundary conditions or business thinking behind them.
So, I thought (as with the first books) that it mix things up by also documenting the business context, the questions, decisions, and the decision-making process itself, as well as all the gotchas and "side-quests", rather than showing "here's how you do it" and then expecting the reader to suddenly make the jump from tutorial hell to actually software engineering.
Overall, it's enormously enjoyable, and I hope it goes as far as the first book, and possibly even farther.

A programming language for teenagers to learn to code by making multiplayer games. I've spent 3 years making the multiplayer completely automatic so you can just code it like a singleplayer game, then flick a switch and it just works. My hope is that teenagers will find it more engaging if they can play their games with their friends. A bit like a combination of Roblox and Scratch.
Currently trying to implement some region affinity so it doesn't just put everyone in the world in the same game. It's rollback netcode so the latency is very good even across continents, but it can't overcome the fact that the world is just too large.
The Goodreads of music. I'm a lifelong music nerd and have developed habits for finding and curating good music, both new and old. I'm codifying my habits and heuristics for discovering new music into an AI-powered social platform that can be used by anybody to widen their horizons in terms of music they listen to and to share their taste with others. https://waxnerd.com/adnan
> This weekend I’m working on mobile app that allows you to upload photos and it turns everything into a stitched anime (ghibli or not) with movements and eventually sound and script. Great to make mini animes from your day or travels or anything.
I vibe coded the above including everything: code, design, logos. Just did it solo. It has all error handling, video generation notifications (it takes a while) and credit system. I myself can't believe it's been done in a month with AI. It's already in closed beta in iOS and android app stores. Let me know if you want to try it out before public release.
My quoted comment above was 28 days ago. This is working on this part time and with a family.
EDIT: Added context.
I'm working on a human-like AI opponent for VR table tennis. It's something I really want myself, love playing table tennis in VR, but with online play you get the latency issues, people that have adopted a playing style which basically hacks the game physics or other aspects, or people who are just plain rude. Playing against the AI is much nicer, but it's not varied or realistic enough such that when you actually play against real people you are ill prepared.
At a very early prototyping phase, but having a ton of fun. https://x.com/artofpongfu
I’ve been making photography software as an indie developer for a bit over a year now:
https://heliographe.net
A few released apps for now that are iOS/macOS, with some exciting more things in the pipeline.
If you’re a photographer who has frustrations with current mainstream photography software (whether capture/edit/publishing), I’d also love to hear from you - you can find me as Héliographe on (mastodon,bluesky,threads,x) or just email me at contact@heliographe.net :)
What a lot of amazing projects!
I'm working on a defense drone.
I built a garage workshop with a Shapeoko 5 Pro, X1C, soldering station, and learned CAD (ok just fusion). I have a lil drone in the air and I'm adding OpenHD for vtx, Rpi for on-edge compute (Jetson would be better but is expensive).
Haven't figured out FHSS or GNSS-denied nav yet (tbh I feel like fhss is gonna be harder). And SITL in a good sim remains to be conquered (ros on osx is a terrible experience). I'm also designing a battery pack that's modular, quick-swap, smart/telemetry.
I've shifted a lot of focus to networking (attending SOFweek in tampa) for the normal fundraising/team-building/customer discovery.
I'm also basically broke due to bootstrapping so I'm about to partner on some b2b ai saas consulting with a friend, today I got Suna up and running, pretty cool.

This is one of my long-standing passion projects, a simple web-based music sequencer built to have a very low barrier to entry.
A tool to organize my life.
All the things that are important to me in one place: notes, habit tracker, brag doc, action log, todos, events, data collection, biolinks, and a lot more.
That certainly sounds a bit boring, and rightly reminds of great tools like Obsidian. However, there was always something missing from the tools, or the configuration was too complex. That's why I started to build one myself. It's a mix of pwa and local-first and Github sync. I don't want a tool that only works in the browser, I also need to be able to continue working seamlessly on my smartphone, and Github offers an endless history that I can view. Plus: I can clone the repo locally at any time.
I don't need a habit tracker service, a tool for notes or a brag doc service anymore. Everything is stored as files that I can access at any time. Other nice features are forms (like typeform) or an infinite number of biolinks.
I've been using it daily for a few months now and have already been able to replace a few services with it.

I am working on a curated database of proxy IP addresses frequently used by bots: https://deviceandbrowserinfo.com/product/proxies-ips
So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources.
I also made an open-source proxy IP block list based on the data: https://github.com/antoinevastel/avastel-bot-ips-lists
7 years ago I posted my dotfiles at https://github.com/nickjj/dotfiles.
4 years ago I made an install script that worked for Debian, Ubuntu and macOS. This made it easier to get going with them.
Over the last week or so I extended and polished that script to make it even easier and customizable, including adding Arch Linux support. The next step is to start installing and configuring GUI tools instead of only focusing on command line tools and environments.
I just used it the other day to set up a fresh work laptop in 5 minutes. Given the script is idempotent I run it all the time on my personal box.
Working on Uncloud [1] — open source tool for self-hosting containerised apps across multiple machines. You can combine cloud VMs and on-premises to create hybrid compute environments, e.g. for cost optimisation or data privacy.
While Kubernetes offers power at the cost of complexity, Uncloud focuses on simplicity for common deployment workflows.
Progress from this month:
I'm particularly excited about the volume management system as it provides the cluster semantics to the good old Docker volumes. It uses a constraint-based scheduler that ensures services sharing volumes are properly co-located.If you're seeking something between "just Docker" and full Kubernetes for deploying applications on your own infrastructure, I'd love to get your feedback on Uncloud.

Silly lisp-inspired language, but it turned into something different as I started asking myself more and more questions, and now it's more of a model for computation that tries to think about computers as different from looms (aka harward architecture). One where self-modification is the norm, where there is no stack unless you make one, and where there's no difference between a program extending itself or the programmer doing it (unlike LISP macros, my language, and model, does not have a distinction, there's no macros).
I'm not doing this because I'm convinced it's a great idea, or because it's going to revolutionize computing, or because it will be a good language, model or beneficial in any particular way, I'm doing it because I think it's fun, neat and interesting to think about (and talk about).
My home-grown daily word game Omiword[1] (previously discussed on HN[2]) is nearing completion. Just a few last features and bug fixes to go, including a hint feature, access to archives, and a sharing feature.

I'm teaching myself category theory, I'll kick back off a local trail, keep notes on the birds I see and read and do the problems in my notebooks. I've got Basic Category Theory by Leinster, and How to Read and Do Proofs by Solow as my references, notebook, pen and a pair of Nikon binoculars.
A Prolog TUI library that sticks to relational/logical programming, is conceptually simple, complete, and performant. Only requires some core ansi features that exist or are easily implemented in most Prologs. Currently have stuff like nested scrollable areas, toggles, frames, buttons, layouts working.
Also, a visual programming language implemented as a PICO-8 script, where the "programming" is done fully in the sprite editor.

Resume builder
7 months ago, I was looking for a job and got frustrated with the current resume builders, so decided to build one exactly how I wanted a resume builder to be.
- Free (like really free).
- No signup, no login.
- Has AI features to improve text.
- Find jobs matching the resume.

https://marketingagents.net - Marketing Automation for Founders who Suck at Marketing. Open Source and Self Hostable
Building this for myself mainly, but hoping others might find it useful. Still very early and building out the bear essentials, but then the hope is to keep reading marketing books and use that to improve the platform.
Around a month ago i posted on HN my side project for sharing Drum Patterns, got great feedback and i've implemented most of the suggestions - https://drumpatterns.onether.com/about/#changelog
Still happy to make little tweaks here and there, since there are some folks enjoying the site.

I'm preparing to leave the corporate world after twenty years and go get a master's in software engineering this fall in Newfoundland.
Pretty anxious about that, given how massive of a life change it is, and how much will be riding on me getting good grades.
I’m working on myself. :)
After three tough years in finance, I’ve decided to start a trip around the world, visiting the UK and the US, spending one month traveling through Japan, and then heading to South Korea.
There might be problems in life that can’t be solved with a three-month sabbatical trip around the world, but luckily, I don’t have any of them. :)
At the same time, I’m exploring ways to apply LLMs to video games and have built a small prototype of an LLM-based D&D system. Let’s see where this goes!
I recently started learning Rust so for my first non-trivial project I decided to build a system for real-time generative art driven by a DSL (defined with Pest) and interpreter that executes scripts for creating dynamic and interactive visuals. The goal is to make human-authored, interactive art more accessible than current methods like GLSL/ShaderToy but without going down the path of AI-generated content, although in theory there's nothing preventing users for using AI to generate scripts for this system. The project uses Nannou for graphics (via WebGL) and input handling (keyboard, mouse, MIDI, audio analysis). It will target WASM and I'll make it accessible as a web app where users can create and share their own projects. I'm also exploring community features to support collaboration and discovery. Still early days, but it’s been a fun way to get deep into Rust by building something creative and open-ended.
I've been building an intentionally annoying app against doomscrolling [1]. I've recently started with marketing, but oh boy is that out of my comfort zone!
I never thought that as an engineer I'd be doing TikToks. And here I am. It's fun to crack the algorithm little by little, but also frustrating because it's like a black box.
So far, I've discovered that going to the point works best. For example, I was sharing student tips and mentioning my app to improve focus. But conversion and engagement were terrible. Instead, I'm doing founder stories and tutorials, which get less views but more downloads. Plus, I can ask people in the comments for feedback on the app!
I'm happy to be doing something that devs overlook so much: marketing. Even if it's tough and slow. It's been an awesome learning experience.

Been building HelloCSV - an open source FlatFile alternative. I've been building this for work and the folks at work were cool enough to let me just build it in open source.
https://hellocsv.github.io/HelloCSV/
It basically runs 100% on your / your users browser, and I'm adding localstorage support so the user can refresh their page without losing their progress.
Love flatfile but it sends your data to remote servers, and we're a healthcare company, so we need to have full control over our data storage
Hoping someone on here will find this useful!
My project is an ongoing one of self improvement. I've spent most of my adult life working on technical stuff, and it's taken a bit of a toll on me.
I quit working about ~20 months ago, started a low-carb time restricted eating regime, lost ~230 lbs, have been doing 15-25 hours of cardio a month for the past year, started going to therapy, got an ADHD diagnosis, read a bunch of classic literature (Middlemarch and The Count of Monte Cristo are my favs thus far), maintaining a 19 week streak of Latin language learning through the killer Legentibus iOS app, and I'm playing guitar every day (trying to nail the the major scale in three different fingerings across all 7 modal starting points).
I miss my old job working with Vitess and Kubernetes a lot (Hi Sam!) but eliminating all work stress has really allowed me to take control of my life.
I am working to better understand AI agents.
What they are. their capabilities, and their and risks and write about it on my Substack

I wanted to know what my kids were doing on the computer: homework or watching youtube shorts, so I built https://screenspy.app to monitor them. Now I’m working on turning it into a product.
Premium tooling to work with JSON Schema (https://www.sourcemeta.com).
I'm a member of the JSON Schema Technical Steering Committee, and been making a living consulting with companies making use of JSON Schema at large. Think data domains in the fintech industry, big OpenAPI specs, API Governance programs, etc. The tooling to support all of these use cases was terrible (non-compliant, half-baked, lack of advanced features, etc), and I've been trying to fix that. Some highlights include:
- An open-source JSON Schema CLI (https://github.com/sourcemeta/jsonschema) with lots of features for managing large schema ontologies (like a schema test runner, linter, etc)
- Blaze (https://github.com/sourcemeta/blaze), a high-performance JSON Schema C++ compiler/validator, proven to be in average at least 10x faster than others while retaining a 100% compliance score. For API Gateways and some high-throughput financial use cases
- Learn JSON Schema (https://www.learnjsonschema.com/2020-12/), becoming the de-facto documentation site for JSON Schema. >15k visits a month
Right now I'm trying to consolidate a lot of the things I built into a "JSON Schema Registry" self-hosted micro-service that you can just provision your schemas to (from a git repo) and it will do all of the heavy lifting for you, including rich API access to do a lot of schema related operations. Still in alpha (and largely undocumented!), but working hard to transition some of the custom projects I did for various orgs to use this micro-service long term.
As a schema and open-source nerd, I'm working on my dream job :)

I'm continuously building and improving https://lectronz.com/, a marketplace for electronic enthusiasts and professionals that focuses on the open-hardware and DIY electronics communities. We recently introduced "Threshold Pre-Orders," a pre-order mechanism that lets hardware creators gauge the market before committing to production/PCBA. We have successfully tested this on four low-volume products already. See https://lectronz.com/u/lectronz/articles/introducing-thresho...
A midi sequencer, which does or is supposed to do what you expect.
In the process of adding stuff like euclydian sequences, and trying to figure out how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory behind it.
It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.
Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol).
I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, etc.).
After researching how the Toyota/Lexus infotainment systems work I found they are highly modular, and actually quite easy to produce custom modules for. The proprietary AVC-LAN protocol is well-understood, and actually makes it really easy to integrate with. The display are just NTSC composite, and touch events (in fact, all button presses, including steering wheel media controls) are emitted on the AVC-LAN bus.
An simple board with some interfacing logic, a DAC and an RPi nano should be all I need to allow good Bluetooth audio integration, and lossless audio via wired USB, both controllable from the steering wheel. You could do all sorts of fun things with the display (such as displaying vehicle status from ODB, lap timer, G-force meter etc.). If I use a RPi compute module then running Android Auto should be quite feasible.
It's just a hobby project though, I'll probably open-source everything. Not planning on commercializing it.
Trying to remain employed. I can’t lose my job in this chaotic simulation we call life.
I've been working on https://asterai.io -- a platform for developing, running and managing AI agents.
It lets you create multiple agents, configure them via the web console (such as LLM parameters and system prompts) and manage their plugins and functionality.
The system is fully plugin-based, where each plugin is a WASM program that exposes functions/tools that the agent can call, and can also hook into the query lifecycle. Because plugins are WASM, they can be written in various languages such as Rust, Go, TypeScript etc. Plugins can also act as libraries, which is possible because of WebAssembly Components (a great piece of software!) -- so you can dynamically call functions from other plugins within your agent, and you get type support for your chosen language too (with codegen via WASM Components tooling).
More recently, I've been working on an SSH server for agents. The idea is that you can add public keys to your custom agent and then SSH into it to talk to it easily from terminal.

I'm prototyping a Depth Anything[1] -assisted segment annotation tool, with an eye toward plant detection in non-agriculture environments (where the backdrop is an endless sea of green complexity). Even if the task I have in mind doesn't pan out, I think this tool could be useful to people for other difficult segmentation tasks.

https://mitte.ai — an AI image generator with focus on quality and details
so you can get logos / icons that doesn’t look AI generated.
it comes with Photoshop-like editor (https://mitte.ai/editor) so you can zoom into details and change / remove anything, or upscale, etc.
I built it for myself but now there’s good amount of paying users as well.
I'm in the midst of a tectonic career shift, from being laid off from a position and place I loved, to another gig while I keep looking for another unicorn role like before.
So most of my project work is home-based, after years of being able to chase (and execute) dreams at work.
On the technology front, I'm finally investing in a proper network core for home. WiFi 7 AP, 2.5Gig core, PoE everywhere, zone-based firewall. Still mapping out DHCP scopes and VLANs, but once that's done it'll be moving on to proper IoT and Home Assistant build-outs to prepare for the Unfolded Circle 3 later this summer. Also looking to redo my two N100 hypervisors off Proxmox and back to RHEL + Cockpit, or some other Linux + KVM implementation; from there, it's all about Kubernetes, Ansible, and Terraform. Really just a lot of oft-postponed side projects because I had amazing fulfillment at work, that I suddenly have ample time for now.
Outside of the tech stuff, I'm still trying to get some decent photos of two local birds of prey that have been hunting in my neighborhood. They seemingly spite me by only showing themselves when I don't have my camera with me, but dangit, I will photograph them.
On the writing front, I've got a few topics jostling around in drafts: speculating on potential futures of LLMs, the internet as a psychohazard, and a series of "fundamentals" to try and teach my non-techie circles more about how computers and the internet work, so they can do some modest self-hosting and get off centralized services. I'll likely dovetail some of them with my own home projects, writing them alongside the documentation as I make progress.
Two things.
I have revived my work on Go Micro (https://github.com/micro/go-micro) and rewritten the v5 cli/api from scratch (https://github.com/micro/micro). As a VC funded company there was a lot of confusion around the tools we were building and we veered off in a direction that alienated the community. With the company dead, funding gone, etc there's an opportunity to rebuild value around the Go Micro framework.
The second thing I'm working on is the Reminder (https://reminder.dev && https://github.com/asim/reminder). As a muslim I feel like it's my duty to spread the word of Islam and as an engineer I feel like an appropriate way to do that is build an app and API for the Quran, names of Allah and hadith. It's a slow patient building of something as opposed to expecting anything from it.
In terms of new ideas, maybe not new but less screen time, less phones, more nature.
Hi all! my name is Patrick and I'm a linux platform engineer out of Waterloo Can. This ( https://imgur.com/a/14YMyVN ) is a collection of Nesticles - lightweight isolated immutable desktop system containers using modern linux compositor technologies and shown on a debian stable host platform and targeting PC grade hardware. These are getting very useful and present opportunities to theme and deeply customize for your personal use or for an organization or company. On average they consume like 600mb of memory per running container, so you will see ~30 envs running there comforably in those screenies. Nesticles is also a platform for unifying desktop and app delivery, providing some building blocks for composing up useful containers. Currently these environments are specified as docker-compose projects, including all of the apps. Could anyone see these becoming useful to you? It kind of scratched a 20 yr itch I'd had since being a young lad configuring desktops painted on cubes and such. I'm shooting for initial support for the following host platforms (debian, ubuntu, steamos, windows, mac). I'd like to bring a launcher to Steam to fund dev and bring the core definitions to the community perhaps as open-source container definitions. Any suggestions or thoughts on Nesticles or lightweight desktop containers? I do view these as building blocks in some larger or more specialized system, but they have utility for desktop use cases now. Ps. I'm also currently on the job market if you are looking for a platform/backend developer - please see https://paddymahoney.github.io . Thanks all, Patrick.
A very misguided project that started with me trying to run Linux on a newly acquired 386DX-40 and has led to me building my own Linux distribution for said purpose
I'm still tinkering on my multiplayer game server framework when not grinding away at my day job.
The idea is essentially: An Erlang-based control plane, supporting ENet and WebSocket connection modes, with Protobuf for messages. Erlang has an excellent concurrency story, and I think it's a great fit for game servers. I've wrapped up a bunch of this work into behaviors on the Erlang side, such that developers can target the "gen_zone" behavior (for instance) to implement a tick-based game server. I'd like to expand that into other types of games, such as turn-based games.
I've also got a Godot plugin for generating a client library based on your protobuf schema. The plugin handles session stuff, exposes functions for client-to-server messages, and emits signals for server-to-client messages.
These days I'm working on integrating Luerl (Lua in Erlang) and Love2D support. I want to be able to take advantage of Erlang on the back-end while writing the majority of game logic in Lua. Further down the road I want to explore hot reloading parts of the Lua game state on the client/server, perhaps with an in-game editor, to develop the game "inside-out", in a way.
Currently working on HN Alerts — a simple free site I made to alert me (via email) to trending stories on Hacker News.
It sends me an email once a story hits a certain number of upvotes per minute, so it's useful for keeping track of breaking news.

Three Kind Words (https://threekindwords.com)
It’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. The first two cards are unsigned, and the last one reveals who sent them. It’s meant to be a slow, kind surprise in the mail.
I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!
https://markdown.ninja
A Markdown-first CMS and website builder for blogs, newsletters and documentation websites.
I've been blogging since more than 10 years, and the only thing that made it possible is Markdown. That's why I've decided to build a complete publishing platform to replace the complex and fragile setups of bloggers and startups. Do you really need a CI/CD pipeline, static site builder, hosting, CDN and analytics just for a website? :/
The platform is currently 100% operational and I'm now working to Open Source it.
The best thing? You can publish directly from the CLI:
$ mdninja publish
Recall Audio - A multichannel audio recording app that has your back, even if you forget to hit record.
Basically it continuously records into a buffer (length is configurable), and if you realize that you wanted to start recording 30 minutes ago you can recall the buffer and have everything saved.
In my work and an audio engineer I was in this situation a couple of times, and since there was no tool for that on the market, I’m building it.

Recently started building a rules-engine for Warhammer 40k, so that I can finally play a game RTS-style in the browser. Hopefully one day I'll get to a public lobby / matchmaking (think chess.com for WH40k).
It's something I've been thinking about for years, but kept avoiding because I knew it'd be a huge commitment and I figured surely someone else would do it eventually. But I decided to finally tackle it and learn some new skills. 40k has literally 1000s of special rules across all the armies, so it's been fun designing a highly modifiable architecture.
I'm building an open source game backend for Unity and Godot: https://trytalo.com. GitHub: https://github.com/talodev.
Talo makes it easy to add systems that traditionally need extra non-gameplay build time like authentication, player analytics and game stats.
Right now you can drop Talo into your game or use the API directly. Importantly, I’ve made Talo easy to self-host and you can point the Unity package/Godot plugin to your own Talo instance.
I’ve been working on a side project called jobswithgpt — after months of building and refining, the first version is finally live: https://jobswithgpt.com
The idea is simple: a job search site that actually works for job seekers. It focuses on listings posted directly by companies (no spam, no middlemen, no bloated sponsored posts drowning out real opportunities). It uses AI to surface better matches, recommend jobs intelligently, and pull out the most important info from job listings automatically. You can also bookmark jobs you’re interested in and track them easily — no signup needed unless you want personalized suggestions.
It’s still early, and we’re improving it constantly. Would love for you to check it out, try a search, and let me know what you think — good, bad, rough — all feedback helps. Thanks a lot for the early support!

Learning Rust by building a simple database using it.
I’ve done my share of programming languages (PHP, C++, Python, Ruby, Haskell) and for the last 10 years I’ve been working in OCaml (which I love so much) but Rust would be a nice addition IMO.
And I never implemented LSM style database before! So that’s fun.
I only just started and the pace will be slow (I have 3h/week to spend on it on a good week), if you are curious: https://github.com/happyfellow-one/crab-bucket
AI bookkeeping for solopreneurs.
As a freelance web dev who also has an Airbnb side hustle, I got tired of expensive bookkeeping for a few transactions per month. I tried DIY, but my time is worth more than that.
Most importantly, both pros and DIY got subtle things wrong and caused me to miss out on thousands of dollars in deductions and credits.
So I’m making an AI bookkeeping chatbot that will handle all that for me. The aim is full automation while surfacing tax deduction and credit opportunities throughout the year. Like wouldn’t it be awesome to just have the research and tax credit or do home office deductions with zero effort?
At the end of the year, Kumbara puts together a series of financial reports that you plug into your tax software or hand to your CPA.

Last year I bought a broken jukebox. I wanted to convert it to be powered by a raspberry pi. I wanted it to work like a traditional jukebox where you used the buttons to input the song number. While there are a few existing projects to convert Jukeboxes to run from raspberry pi, most of them used a touch screen or didn't work well on RP5 which is what I had or the current version of raspberry pi os.
So despite not being a programmer, barely knowing a little javascript, and nothing about python, linux, or gtk, I was able to use AI to muddle my way through to creating a program that takes the input from a numpad, looks up the song from a list, sends it to mpd, and posts a picture from the album art embedded in the music file. https://github.com/jccalhoun/mpcButtonJukebox

I'm working on Damon[1], a Nomad Events stream operator that automates cluster operations and eliminates repetitive DevOps tasks. It's a lightweight Go binary that monitors the Nomad events stream and triggers actions based on configurable providers.
A few examples of what it can currently do:
- Automated data backup: Listens for Nomad job events and spawns auxiliary jobs to back up data from services like PostgreSQL or Redis to your storage backend based on job meta tags. The provider for this is not limited to backups, as it allows users to define their custom job and ACL templates, and expected tags. So it can potentially run anything based on the job registration and de-registration events.
- Cross-namespace service discovery: Provides a lightweight DNS server that acts as a single source of truth for services across all namespaces, solving Nomad's limitation of namespace-bound services. Works as a drop-in resolver for HAProxy, Nginx, etc.
- Event-driven task execution: Allows defining custom actions triggered by specific Nomad events; perfect for file transfers, notifications, or kicking off dependent processes without manual intervention. This provider takes in a user-defined shell script and executes it as a nomad job based on any nomad event trigger the user defines in the configuration.
Damon uses a provider-based architecture, making it extensible for different use cases. You can define your own providers with custom tags, job templates, and event triggers. There's also go-plugin support (though not recommended for production) for runtime extension.
I built this to eliminate the mundane operational tasks our team kept putting off. It's already saving us significant time and reducing gruntwork in our clusters.
Check out the repository[1] if you're interested in automating your Nomad operations. I'd love to hear your thoughts or answer any questions about implementation or potential use cases!

https://indiantranslate.com
It's a translation map of Indian languages - type in a word, see the translations across 22 languages.
I was inspired by this HN post (https://news.ycombinator.com/item?id=43152587), and wanted to make something similar for India (which has similar linguistic diversity). Translations are fetched with Google Translate, but I also display 'romanizations' (transliterated into Latin script), which are generated with a local ML model.
Now that it's done, I've mostly been working on a little Markdown-to-HTML parser in Haskell.
We're working on the successor to Weebly, with https://www.articulationsites.com. My partner and I were founding engineers at Weebly. It's clear that the brand is in decline at the hands of Square, and it drives us every day to make a great alternative that Weebly users can rely on.
I'm working on a universal tool to create and print custom dust jackets.
I like collecting books and have lots of series, but editions and cover/spine designs changes all the time for no good reason. Especially for long series it's near-impossible to get a collection with consistent styles, which I find frustrating. And when buying rare or old second-hand books online, it's even worse.
The app will allow you to enter your book information (title, author, size, summary...), then choose the design/layout. You will then have the option to print it by yourself (for free - if you can find a big enough printer) or get it printed by a professional.

I’m working on LookAway (https://lookaway.app) to help people stay healthier and more productive during prolonged screen time.
My main challenge has been making meeting detection more robust -- it currently uses both mic and camera activity, which led to a lot of false positives. In the next version I’m switching to mic only (the camera caused most of the noise) and I’ve added a way to identify which app is using the mic, so users can exclude non-meeting apps.
I’ve also added plenty of small tweaks throughout to make LookAway even less interruptive. I’m excited for the next release!

I recently found out my wife wants a gecko, so I’ve begun planning for a mega-paradise. I want weather systems, every sensor I could possibly ram in there, cameras, and more. Planning to jury rig a toilet setup to run water from the reservoir to the rain system.
The gecko comes from New Caledonia, so my goal will be to replicate that environment as closely as possible. This will be difficult, since most of the plants on the island are only found there, but you can get surprisingly close.
One awesome fact I learned about this: conifers actually started out in warm climates. They just got out-competed once angiosperms (flowers!) came about.

Erlang-RED[2] a combination of Node-RED[1] and Erlang to create a visual low code programming environment for Erlang based on the principles of flow based programming.

I just finished a small personal project: a self-hosted web app which stores and indexes my archived emails. None of the existing options I tried were very good so I made my own. A simple Rails app that ingests .eml files and stores the text in postgres for full-text search.
I learned a lot about text encodings, multipart emails, inline attachments, postgres' tsvector/tsquery, etc. I'm particularly proud of how I was able to use `WITH RECURSIVE` to get an email's entire thread, which seems basic but the other archive apps I tried didn't have that feature.
https://github.com/ndouglas/whispers
Whispers is a self-organizing, belief-driven mesh where nodes propose, verify, and evolve solutions through dynamic, decentralized consensus.
Basically a shared knowledge graph of proposed partial inferences in CRDTs using verification as a merge function. There're some issues I know I'll run into with e.g. admissibility but I have some solutions in mind.
I'm in the very early stages but I think it's a simple idea so I have high hopes for a cool demo soon.
Need to renovate an old house, built in the 50's, extended later in the 60's, 90's and 2000's. I want to calculate the heat loss, energy requirements to install a heat pump. So, I am writing a relatively simple Python program to compute the heat requirements (max total and max per room) to get the possible energy savings if changing windows, isolating etc.
By doing the calculations myself, I can play with different scenarios, I can also integrate the effect on the material quality uncertainty. Nothing fancy, but it fits my needs.
I'm working on a little 2D action puzzle game in Go on top of SDL (with bindings via https://github.com/veandco/go-sdl2). The prompt I've given myself is "Chip's Challenge meets Hotline Miami," but who knows how much of either of those elements will remain after I keep evolving the capabilities and general feel of the gameplay. For dev graphics I'm just cobbling together sprites from various pixel-arty asset packs I've purchased on itch.io, but in the future if I want to commercialize it I'll probably want to work with an artist to develop a unified look-and-feel for the game--I may even switch to 3D/2.5D depending on how the tone and my workflow evolve.
I've experimented with Unity, Godot, and GameMaker in the past, but for the time being I'd like to see what I can accomplish on my own in Go to keep my dev chops sharp especially since I've moved into an engineering management role at my job (which has nothing to do with game dev but is increasingly employing more Go source throughout). Something I've realized as I've been applying good code organization and reusability is that I'm essentially building an engine for anything top-down (hesitant to say "isometric" since I know that means something graphically specific)--RTS/TBS/tactics/RPG all seem doable with what I've built given a little bit of extra logic on top for each.
Working on a fridge camera; no good solutions exist and I need it to avoid that feeling that I get when I dump my large bag of fresh vegetables.
I was inspired by this comment https://news.ycombinator.com/item?id=43745615 and built a simple workflow to process all my photos: for each photo it generates a text description, a list of keywords, and the mood.
My plan for the next step is to detect faces, ask the user to label the most occurring faces, and then label all images accordingly. This step seems a bit harder than just feeding the image through Gemini and asking it to create labels.
This is going to sound ridicilous. But in the past month, I have been working on an AI agent that can write its own AI agents. I can give it a task like: "Please create an AI agent that fetches the weather, and sends me an email every morning about some interesting stuff to do". The agent then goes through a loop of requirements gathering (with my input), and then starts building himself.
It self-references its own documentation, spins up a docker container and runs it. Alongside it builds tools, and registers both the agents and tools in a central system, so that it has knowledge of what other tools and agents it can use. I am not talking about "I am working on the theoretical idea of an agent that can build agent", but this is actually working. And I know of several other teams that are building stuff in this direction, its very fun.
I left behind a very well paying client to go full-time on this because its just so much fun. I have connected it to telegram, so now while I am at the gym, I can actually build software... the execution may take anywhere from a 10 minutes to an hour. Which is time spend writing and testing the code, then spinning up a docker container and fixing stuff, prompting me to create accounts somewhere an provide an API key. By far its the most complex project I have worked on, and all my friends and colleagues are slightly going crazy by seeing the outputs.
I'm working on a cookie clicker style web game that's secretly about AI safety: https://preview.mancato.nl/clean
My primary goal is to make a game that's fun. Secondary goal is to make you experience why an AI might do things you don't expect. Specifically, to further instrumental goals like collecting resources, refusing being turned off, things of that nature.
There are two endings currently but I'm working on adding some more.
An IDE for agents, that includes a general purpose agent inside so developers don't need to start with a framework or from scratch. It just works, out of the box.
I feel that the software development lifecycle for agents is uniquely iterative and requires a different set of tools and environment, so that's how this came to be. First we built the general purpose agent -> now we build the IDE around it.
For the curious: https://trypointer.com/

The Want Build System
https://github.com/wantbuild/want
https://doc.wantbuild.io

Last month, I started playing around with code sandboxes and how LLMs might interface with them and wrote a little blog post about it [1]. I then took the code and vibe coded my way to a multi-tenant (untested!) sandboxing server that lets you run arbitrary Docker containers and provides a simple HTTP interface and UI. A cute, novel idea is that you can fork containers easily, as seen in the video in my repo:
https://github.com/ammmir/sandboxer
It may not be useful, but it's been fun, and I've honed my gut-level experience in Docker, Podman, Linux namespaces, Checkpoint/Restore, CRIU, and more. The ultimate goal is to hand each AI agent iteration a sandbox of its own (forked from the previous iteration), and have it build apps in private sandboxes. You'll be able to view intermediate progress as the app is being built (or failed rabbit holes), since each sandbox gets a unique URL automatically. Like, imagine if each commit of your git repo had its own URL to preview the app!

Little personal project that started as a means to try out AI tools that can talk to each other. Turned out to be super useful for building and debugging complex AI automations. I haven't had the time to promote it. But maybe someone here will find it useful.
(1) Business process modeling tool where processes are data and not graphs. I am doing it according to the USM method. USM is kind of "open source" service management method, although it works on different level than other frameworks and standards, and is compatible with all of them.
This makes it possible to create a kind of requirement "programming language" where the requirements can be evaluated. With this language it becomes possible to create cross-references from various compliance standards/frameworks, like ISO27K, to USM, and automatically evaluate the compliance.
(2) Dance event calendar in Finland, running in production for over a year. 1-2M page views/month. Django app, but I am now implementing a copy of the unauthenticated user views to S3 bucket and delivering it through Cloudflare.
(3) Django app to handle all the data related to custody trial. Emails, SMS, notes, official records, voice memos, etc. can be attached to a timeline, and tagge and searchable. It has command line interface for adding data, in addition to UI, so I can quickly add notes and attach files.
I’m still working on these.

Positron, a data science IDE. Has roots in RStudio but it's built on VS Code and has robust support for both Python and R workflows. If you use VS Code and install a bunch of extensions to try to make it a competent R/Python data environment, you'll probably love Positron.

Currently working on http://untamed.earth
Scratching an itch, the intention is that its a map, centered on the users that shows all (configurable) things of interest near by. Think of Atlas-Obscura but much more local - eg AO doesn't list every prehistoric burial mound on the planet, but I want to know where they are ;)
I wrote a novel in French a couple of years ago that I want to translate to English. The way I do it is paragraph by paragraph: copy/paste a paragraph in OpenRouter (Sonnet or Gemini), get back the translation, and rewrite/adjust it.
It works well but copying/pasting back and forth gets old very fast, and it would be better if the process was done inside the word processor. For some reason (various reasons) I still use Office 2003, which doesn't have any AI feature. (It does have a "translate" function but it's awkward to use and not very good.)
So I wrote a macro to send selected text to OpenRouter and replace with the response (with a system prompt that says to only output the translation, otherwise most models start with "Here's the translated text:")
I had never written a macro in vba; I got started with Sonnet and adjusted many parts with the help of StackOverflow (which turns out to have more information about vba than Sonnet...)
And finally it worked; and it turns out to be an incredible boost to translation productivity!
https://github.com/runsecret/rsec
An easier and more secure way to work with secrets during local development. It’s open source, cloud/vault agnostic, and doesn’t require a single line of code change to use. I call it RunSecret.
RunSecret is a CLI that replaces your static secrets with “secret references” in your ENV VARs (or .env files). These references are then replaced when your application starts up by reaching out to your secret vault of choice - making your .env safe to share across your whole team and removing a slew of gotchas when you use git ignored env files. Even better RunSecret redacts any instance of these secrets from your application output, reducing your chances for accidental leaks.
The approach is inspired by the 1password CLI, but built for the rest of us. I’ve got AWS Secrets Manager support pretty well baked, but the goal is to support all major secret vaults within the next couple of months (Azure KeyVault is already in progress).
I've been working on https://textquery.app -- query raw data from your desktop.
I love exploring data, but it always felt clunky to juggle multiple tools, write code/commads, just to import and query a dataset. While there are multiple GUI tools for databases, none are focused on raw data.
TextQuery is the tool I built to solve that. You can import CSV, JSON, and XLSX files and start querying them instantly using SQL. Want to create a chart? Just hop over to the Visualize tab.
I'm also rolling out a major update this week — adding tabs, filters, a redesigned UI, and keyboard shortcuts.
Looking ahead, I’m planning to expand support for more formats (like Parquet and ORC) and data sources (like Postgres and BigQuery), so you can import data from anywhere, and query it right from your desktop. Something like a local data warehouse. With Apple Silicon, the capability of a desktop can make it very cost-efficient compared to something like BigQuery, Snowflake, or Athena.
Happy to hear any feedback!
I'm working on my own mini time series database.
It only stores (timestamped) floating point values with a series id and uses a B+Tree as the backing data structure. Querying is done with a lisp-like query language.
https://mujo.app I’ve been building a minimalist productivity app for musicians. Mujo adds time tracking, task management, notes and other “practice journal” tools into a simple metronome interface. Been hacking at the iOS version for a while, and starting to think about Android.
A reactive notebook with managed side effects for building backend/AI-engineering pipelines.
Reactivity can update the state of the notebook automatically, so you don't have to keep track of which cells to execute again. Side effects are managed to make it easier to reason about while maintaining reactivity and ability to interact with the outside world.
I'm working on a correlation matrix with Svelte 5.
It has hierarchical clustering, rolling correlation charts, a minimap, time series data detrending, and 2D matrix virtualization (to render only visible cells to the DOM).
It has up to 130K matrix cells and correlates up to 23.5M time series data points.

I'm writing a study about how to write likely-correct studies ... :)
This is a second part of a series on likely-correctness, the first is how to create likely-correct software: https://www.osequi.com/studies/list/list.html
Debugging co-routines / threading is a pain in any language. I'm a big believer in observability anyway so this isn't a leap. Nor is it the first time I did this very thing, but last time I had implemented a console and it was a console command. This is in a product written in Python which implements a DNS gateway for Redis:
The implementing code (not including turning it into a DNS response) is surprisingly simple: https://github.com/m3047/rkvdns/blob/f6fba9523a83aa5125378bb...Pretty nervous as this is my V0.1
MindJam helps brands, studios and creators understand their YouTube communities.
MindJam analyses millions of YouTube comments to instantly reveal the unfiltered voice of your audience – their true sentiment, emerging themes, and the topics they really care about.
Here is a sample analysis - https://mind-jam.co.uk/analysis/HPMh3AO4Gm0?utm_source=hacke...
I didn't intend on building MindJam... I wanted to learn about LLMs.
At first I wanted to see how Laravel would/could work with an LLM and after doing some reading I ended up learning about OpenAPI 3.0 Schema and Multi-Modal RAG.
In the last few months I have built on top of Gemini, Claude and OpenAI. All have their perks and quirks.
I am hoping this learning is only the start of a pretty cool journey.
I've been working on mock: https://dhuan.github.io/mock/
the process of creating APIs for testing and automation should be as easy possible. the tools that exist nowadays for this purpose aren't good enough IMHO, which led me to build it.
I'm working on running sequences of heap operations (insert and delete-min) in linear time instead of O(n log n) total time. It's a silly little project in theoretical computer science I have.
Crucially, to make this bound work, you only learn the final state of the heap, not which element got deleted when.
I'm also building a simpler soft heap.
Working on: Pantry Recipes – AI meal generation based on what’s in your kitchen
Over the past few weekends, I’ve been building Pantry Recipes – a mobile app that lets you quickly generate recipe ideas based on the ingredients you already have at home.
The idea is simple:
- Save or quickly select ingredients you have on hand - Tap Generate Recipes and get ideas instantly - You can also describe what you want to make free-form (e.g., "cheese omelette") and the app will generate a recipe for you.
The app is free for a number of recipe generations, then offers a low-cost subscription if you want unlimited use. It's live on the iOS App Store now: https://apps.apple.com/us/app/pantry-recipes/id6744589753
Happy to answer any questions if anyone’s curious about the tech, UX challenges, or what I learned from launching!
I'm working on a travel planning application. I know a lot of other apps exist, but I'd like to build one myself.
https://github.com/kenrick95/ikuyo
So far it has some sort of activity calendar + expense tracker
There's still so much ideas to implement, like adding map, improve UX of creating activities, to-do list, etc
I've used it once or twice of a short trip, but in 6 months time, I'll have a 2-weeks trip, so that's my self-imposed "deadline" for this project
Anyway this project is a pure static web page and all the 'back-end' is handled by InstantDB ( https://www.instantdb.com/ ) after I saw their submission on HN >.< So far it has been quite a good experience overall except maybe the permissions model which can be a bit confusing to me
Main work: tokenization of real-world assets, but on the side I’m building two projects as a solo dev:
Looking for like-minded people interested in exploring both the technical and business sides of these systems.I'm working on an unified MCP server that can search and use a large number of tools. The current way of using MCP server (adding each MCP server directly) simply doesn't scale. If your AI agent needs to use 100 tools, you need to manually configure a lot of MCP servers. And when you feed those tools to the LLM, it may get confused and tool calling accuracy starts to drop.
This is why I'm building a unified MCP server with just two meta tools: - Search Available tools - Execute a tool
When I want to send an email, I ask LLM to use the Search Meta tool to search for Gmail related tools in the backend, then the meta tool returns the description of relevant tools. The LLM then uses the Execute meta tool to actually use the gmail tool returned. https://github.com/aipotheosis-labs/aci
I recently started working on a fishing journal/log kind of app. I got that idea last year when returning from fishing with dad, that it would be nice if we could track what we caught each time we went fishing, where we went, and to track some details (water and wea details). There apps that already do that, and one could also use Excel or just paper notebook, so I'm making this mainly for us and his friends to use. It's still early, but I'd like to add groups so you can exchange messages or catches with your friends, add stats allowing you to see for example at what time and where you caught most fish, or using which lure or bait. The app is in Serbian though, but here's a link if you want to check it out: https://buckaros.com
I’m building a small integration to take scheduled transactions in YNAB and display them in any normal calendar application. I’m hoping to add historical transactions one day as well to help with reconciling.
https://calendarforynab.com
Any feedback is welcome!
I once saw an idea on here[1] about putting a lot more historical information into a calendar, including past activities. It resonated with me and I wondered if bank transactions could be part of this activity layer. At the time I was working on a real-time integration between my bank and YNAB so I was already thinking about the space.

Working on launching a podcast and associated website which I hope to use as the launchpad for all my ventures going forward. 2025 is the year I ditch my corporate job and finally start working for myself. At least, that's the goal. I'll be the master of my fate; the captain of my soul.
I know its been done before but im building/tinkering on a window manager for windows called "Doors". https://github.com/A-Waters/doors
Ive got a MVP right now, but i'm reworking the region build system and potentially reworking the underlying designing to follow a more tree based approach for managing the windows
I've just tried other windows managers on windows and felt that have either been slow or buggy and wanted something that looks nice. My inspiration is based on Hyperland, as im currently dual booting and when I work on windows, all i want is a nice window manager.
still very early in development but im excited for its potential.
This also goes in line with my current studying of the windows OS, so its a bit of learning and then working. :)
Work wise I'm building a discrete event simulation with pysim. I manage the autonomous vehicles program and underground control center for the subarctic mine I work at, and we've desperately needed some means to evaluate efficacy of designs and forecast productivity. Using it to model scoop-truck movement and loading operations, and it's working very well. It's been a joy. I've been taking advantage of the enormous context window of Gemini 2.5 pro to have it make upgrades, fix issues, and just generally doing all the legwork.
Personally I'm having fun learning some web design and three.js as I try to debug the very tricky issues with my new personal website loufe.ca using AI is fantastic but you need to micromanage when things get complicated, I find.

I'm working on a better frontend (in sveltekit) for Udio - music generation app. Udio has good models to generate audio, but awful UI and organization/management tools. My frontend allows collecting all the generated content from udio, organize them by topic, rate them with 5-star rating system, add custom labels, filter by these, make playlists, generate prompts and create an arbitrarily long generate queue (udio allows you to create 4 prompts simultaneously so you can sit in front of UI babysitting it if you don't have custom tooling and you want to actually use your 4800 credits you paid for). I use LLMs heavily here, so the quality of code is so-so, but work very well for me and I'm having a lot of fun with this.
I'm working on a fantasy console that work on iOS and iPadOS https://github.com/moechofe/LowResRMX
My goal is to create games on the go, during my commutes.
It's a fork of https://lowresnx.inutilis.com/, there is some videos of my progress on https://www.youtube.com/playlist?list=PLtmKVaz_2Cxe6pG7VbQfw... and a Discord channel https://discord.gg/jcT9CXDgHB
Mostly on an AI-based tender analysis tool which is focused on the construction industry, https://www.tenderstrike.com
It's a pretty specific niche with interesting challenges like massively varying project sizes (ranging from a few pages to 20,000+ documents), a high importance of graphs / charts, and very different extraction tasks (from more qualitative analysis to quantitative, exhaustive lists which is still a pain point).
Built most of the pipeline by hand, mostly because I started this earlier than many RAG tools came out, but I am glad I did because we needed a bunch of adjustments and changes that might have been hard with something ready-made.
I’m building ninja.ai — it looks like a one-click App Store for MCP Servers, but the real goal is much bigger: creating a “Universal Fabric of Context” that lets AI tools tap into structured information across the web easily.
It started when I found it surprisingly hard for my partner to install and connect MCP Servers — even simple ones. I realised if we want AI agents to really interact with the web, it needs to be as easy as installing an app.
Right now, you can browse, install, and connect servers in one click. Over time, it’ll make AI integrations as easy as installing an app — no messy APIs, no custom scraping.
If you’re working with AI models, agents, or data-heavy tools, I’d love to hear what kinds of “context pipes” you’d want to see added.
I’m working on JSON Query (https://jsonquery.app), a tool that lets you store, categorize and query JSON using jq in the browser.
This is a complete remake of the original I made a long time ago for the Mac App Store, sharing only the name. I realized it was better to use the jq language since it was already familiar to many people and way more powerful than designing my own query language. I also do not agree with Apple's App Store command and control so I've decided to make it a web app, and I'm astounded at how much more powerful web apps and their DX are compared to native application development in the Apple world.
Worked a little on Server Radar [1] again, the Hetzner Auction price tracker.
It's my fun little project to resort to. Implemented dark mode, sorting, grouping and various layout improvements. Also added a Drawer with Auction view the other week. UI is finally fun again with component libraries and LLMs.
Oh, and I added a Cloud Server Availability [2] page as I noticed people on /r/hetzner were complaining about lack of resources. Looks like their Cloud offerings are going quite well.

AI has taken over the hype in sales and go-to-market strategies. But for independents, solopreneurs, professionals, and many founders or CEOs, relationships and partnerships are still central.
I think sales will bifurcate: either fully automated self-sale, or fully relationship based. All of the major CRMs (customer relationship management) software are going all in on AI and sales automation.
I think relationship sales is going to see an increase in comparative advantage. I've always been a relationship seller but the current crop of CRMs are not designed for me. So I've built https://humancrm.io/ to scratch my own itch.

I work at a small startup trying to hire engineers and got tired of looking through resumes. As Joel Spolsky points out, they're not great indications of technical ability. Instead, I decided to throw together a take-home challenge that applicants could access via an API. "If they can't solve the challenge, I don't need to see their resume," I told myself.
FizzBuzz.md is a better version of the solution I built for work. It lets applicants send questions and submissions to configurable email addresses via API so the email addresses aren't exposed directly. (Less spam, FTW)
Building an app that extracts key information from PDFs + highlights citations.
You provide a PDF and a JSON schema defining what to extract, and it returns the extracted values, the citations and their precise locations in the document.
This is especially valuable in workflows where verification of LLM extracted information is critical (e.g. legal and finance). It can handle complex layouts like multiple columns, tables and also scanned documents.
Planning to offer this both as an API and a self-hosted option for organizations with strict data privacy requirements.

I'm building https://www.howbazaar.gg/ which is a companion website for the video game https://playthebazaar.com/!
I was enjoying playing the game, there were some shortcomings in the info it provided, I dug around and found the info in game files, and decided to make that info more accessible. It was quickly a hit with the community and got official support from the game company. Trying to add enough features to take on the big players in this space and make working on it sustainable.
DodgeALL Party Mode! It lets people with smartphones connect to a player in VR (DodgeALL for Meta Quest) and decide which obstacles are launched at the player, that they then have to physically dodge in real life (there is no fake movement).
I also "recently" (~2 years ago) added Twitch interactive mode so that streamers could play against chat, but so far haven't gotten anyone to play it on stream (that I know of). While I was adding features, I realized that I could easily make a version that works over WLAN.
On the side I'm working on a mixed reality mode but it's been a slog trying to adapt the game to fit into various room sizes.
Working on a series of interviews with gamers about how the hobby is part of their lives, called Unmuted [1]. It's been awesome to interview people from different backgrounds and see how gaming has influenced them.

My team and I are working on embodied AI. More specifically, focusing on humanoid legged robots for long horizon tasks combining navigation and manipulation/interaction.
We've recently put a paper out in arXiv (https://arxiv.org/pdf/2503.12533) and the project page is: https://beingbeyond.github.io/being-0/
BAAI is also hiring! No fully remote positions though. :-/
I have two:
The first is a preventive maintenance and calibration tracker (https://pmcal.net) that was born out of my day job as an engineer in small business manufacturing.
The second is an AI engine for pulling structured data out of incoming email (either via IMAP on your email server or via SES). If you think of the engine that powers TripIt, they had to write about 10,000 different ingestors for each airline and hotel and travel booking site. With a structured output AI, the need to write specific ingestors goes away.
Chrome extension to organize web-based learning into journeys. Uses the tab group API and sidebar to bundle a set of websites into a "container". Sidebar tracks progress through visiting the pages.

I'm working on a site that lets you tile and watch multiple videos from different platforms all at once.
You can drag and drop links from YouTube, Twitch, TikTok, or Kick --and they show up in a grid.
You can reload or remove streams without refreshing, save mixes for later, and share them as links. It works best on a really big screen --phones aren't really supported and even notebooks are too small to get much benefit.
There's no backend, no login --everything runs in the browser.

I am working on a telegram bot deployed on cloudflare which is just a basic app for van drivers to sign up on a fixed location near my area and see which drivers are online and see how many people have sit in a van which the drivers can increment/decrement by just chatting with the telegram bot who want to go to a popular spot where I have to go to quite daily because I am studying at a place which is way far away and its the most economical and sane method to travel..
Yet my problem really arises that its too luck based, sometimes I can be the last guy, Sometimes I can be the first guy so I have to wait for the van to get fully occupied which will take a lot of time...
I have just made it, and I find it pretty nifty, I made it all completely via AI and this one absolutely crazy good youtube video on deploying telegram bots on cloudflare...
Also, I had seen this telegram bot ai maker idea on HN a few days ago, So I had also created a project which you can chat with the microsoft deepseek r1 post training bot for free because the api key of open router for this model is free, It doesn't have incremental streaming or multi chats, really basic, and It can generate me the code but I am not sure how I would deploy that code .. , I used to think its easy but not... ,any resources out there? (Though I want to open source this, but I am not going to be building this ai idea further because I lack time and I have to study)
Transitioning from iOS development to web and embedded development with Elixir (Phoenix/LiveView and Nerves).
The direction Big Tech is heading made me reevaluate what is important in my career and life.
A few things:
- Snapshot (https://apps.shopify.com/snapshot): AI generated product photos for Shopify. Previously used Flux and Stable Diffusion but always had quality problems. Was very tricky ensuring text remained the same and the product fit into the generated background. Just integrated the new OpenAI image generation model and results are much better however their masking feature doesn't work properly so need to wait for them to fix that before I can offer the same feature of keeping text/fine details the same
- Lurk (https://apps.shopify.com/lurk): New one I just launched - allows Shopify merchants to track the prices of competitors and adjust their own in response with dynamic pricing rules. It's cool because you just have to paste a URL and it uses AI to figure out the price. Again, there's a surprising amount of things you need to figure out to make this work reliably at scale (e.g. popups, ambiguous HTML, location-based pricing, etc.)
- Origin UTM Tracking (https://apps.shopify.com/origin-utm-tracking): Simple UTM analytics for Shopify stores. Acquired this last year and its being growing nicely.

Currently working on a USB/Bluetooth to Sega Dreamcast controller adapter.
It's based on the Raspberry Pi Pico 2/W board and originally started as a fun project to play around with the PIO features of the RP chips and get my Steam Controller working on the Dreamcast. It has since expanded to support more controllers, keyboards, mice, and acts as VMU - the Dreamcast's memory card - while plugged in. Building the dongle itself has also been a fun exercise in 3d printing, cad and pcb design.
I'd really like to expand the amount of supported USB devices as I only have access to a limited amount of hardware that I can test myself. I've started looking into if I can use the SDL Game Controller DB (https://github.com/mdqinc/SDL_GameControllerDB) to kind of crowd source support for a bunch of controllers. I'm definitely open to other ideas though. I feel like I'm slowly learning that USB controllers are minefield of one-offs and edge cases.
I'm working on an IDE for lawyers: https://tritium.legal

I'd greatly appreciate any comments.

After working on it for a while, I noticed there’s a stigma around using CORS proxies, often associated with fetching undocumented APIs.
While that’s sometimes true, I’m hoping to change that perception, to show that they can also be used for accessing real APIs. It just requires the proxy to correctly handle credentials and secrets.
The idea is to open up more possibilities for building static-first apps without worrying about CORS.

I started experimenting and I think this builds out pretty neat estimations from jira tickets/other descriptions. When I was sitting in the CTO role, I spent a ton of time talking with people about how long/short various projects would be. When I was a developer, I hated the estimation piece because it felt like it was both keeping me from building and was almost never done with enough context to get really accurate results.
I was playing with the OpenAI API and I noticed that they can actually return a set of probability x next tokens and I thought that it might actually give you kind of cool ways to see the distribution of potential outcomes. (You can see an example here: https://universalestimator.com/estimates/c68db45b-7622-4bab-... that looks at a detailed ticket for implementing filtering on a dashboard.)

After trying to start a business for a year, I basically gave up negotiating with VCs.
My current goal is to spend half of my time on the development and maintenance of open source projects, such as Glicol (https://glicol.org/).
The other half of my time is to do some business that can generate profit from day 1.
I just found that the VC model is not suitable for my current situation.
I am working on an administrative app for small shops. It has inventory, invoices, quotes, returns, purchase orders, payables, receivables, finances, etc. It's almost ready for v1, just finishing the final touches to start onboarding first users

If you like what you see please let me know, all feedback is appreciated
Did a Show HN about a month ago, but we're hard at work building dédédé [1] - it's a not-for-profit website that invites people to casually share the "good, bad, and why"s of urban spaces.

I’ve been building an Elixir app to poll RSS feeds and pipe new entries to Discord.
Performance is rock solid, and it’s almost ready to release, I just need to tweak a few things (like free trial with no CC).
I have a very long to do list, and ultimately want to extend it with “change detection”, e.g. notify when an HTML element on a website changes.
All feedback is welcome

Some music control using Wii balance boards thing: https://gitlab.com/TOGoS/SG-P27
So far this has means orchestrating a set of processes just to talk to bluetoothd, automatically connect to boards, guess which /dev/input/event* device each one is associated with, and start reading those and sending data somewhere over OSC. Every step of the process is about 10 times as difficult as I initially expected it would be, which is why, after months of work, I'm still putzing around with process orchestration instead of actually doing anything with music.
The bit of hair on this yak that I'm currently shaving is building a TUI library for Deno so that I can build a nice dashboard for keeping tabs on the state of all the different pieces. I prototyped a bit of the orchestration process in Node-RED, which was neat, but not exactly what I'm going for. There is a TUI library for Deno already, but it's kind of buggy and non-ergonomic for my brain.
Been working on https://www.labophase.com/ I mainly built it to save money on subscribing to multiple places to try out a new ai with a privacy focus.
Basically it's an AI aggregated service where users can prompt multiple ai models at the same time/place for free and/or under one subscription fee ($20).
I am working on the https://moviemovie.club/about, it's a tiny website about film review.
It works like a run club, where you have to make a review first to see other people's reviews.
I am currently implementing watchlists, comments and a mural to make it feel a bit less lonely. Right now I like the UI but it feels to lonely.
I am building a service to make accessing AI as easy as sending email called ThreadWise
https://threadwise.app
You can email prompts directly to your ThreadWise address and get instant AI-powered responses, essentially an always available co-worker. Another great feature is the ability to schedule recurring tasks and since the AI has web access, you can get things like:
Daily mortgage rates or airfare price monitoring
Weather and news summaries
Sport scores, jokes, quote of the day
Pull data from public APIs (and more)
So you can essentially use it as a personal newsletter, crafted to your taste.
The free tier will let you test this out for free! I am looking for some feedback/criticism, testing, and additional ideas and I am open for collaboration if you have experience with sales. Also open to hearing which scheduled tasks people would find most useful.
Why I built it: I noticed a trend online, as well as with family/friends, that people would like to have a quick access to AI in instances where they couldn't always install apps or use browser-based tools (such as in remote/low bandwidth environments). This is when it him me, email clients already have all the features needed to interact with an AI (text + attachments) and I quickly got to work.
Some of the advantages are also that since there are no new apps, or browser tabs needed, the tool is ideal for companies who don't have the bandwidth to setup full fledged AI solutions on their own. The companies can choose either between public LLMs (e.g. OpenAI) or host everything on-premise with locally run models, so no data ever leaves the premises.
Eager to hear what you all think!
https://extension.scaledown.ai
I realised that I'm a horrible prompt writer and so are many other people. So i created this extension to help me write better prompts, using templates, save prompts, and optimize it for better performance. No login, not paid, just a useful little extension. Check it out!
I’m working on SimpleeFood, a simple self hosted recipe app.
https://github.com/abhchand/simplee-food
I found most of the offerings out there to be too bloated. Recipes are a simple thing - you want to store them, search them, and view them easily.
It has a full screen viewing mode for easy cooking with your tablet or phone.
I'm still working on Habitat. It's a free and open source, self-hosted social platform for local communities. The plan is for it to be federated, but that's a while off yet. Just this weekend I began adding cypress tests. I can finally see an official release in the distance!

I have been working on a intentional farm to table co-housing network spanning from S.Flo, ATL ,to Cape Breton in NS CAN. It's been a humbling experience of meeting, learning and living with great interesting people to say the least. Each property is different but all are tailored to reduce hospitals readmission, provide various high risk groups housing opportunities, and supply fun lasting agrarian experiences. Each member has access, via provided transportation to the other properties and it's different resources. The struggle has been being a father of six, husband and career man alongside this project. I resign from my career almost 3yrs ago thats helped and hurt as struggling to secure income at times, I have learned and relearned alot! I can say I'm still moving forward and excited at what's ahead! https://www.funnyfencefarm.com/

I develop Chips of Fury, a poker app for playing privately with friends. Currently I am building support for lots of home game variations like pineapple (regular, crazy, lazy), different Holdem variations like Super, reverse, super reverse, blind man's bluff etc and many more. I am thinking about how to implement AI bots for a wide range of variations.
I’m working on Vystery (https://vystery.com) - a visual puzzle game where you strategically uncover an obscured image bit by bit to figure out what it is.
There's a limit to how many reveals you can do to make your guess.
I’ve recently added hints, spare moves, and an easy mode, as some days are harder than others.
A native PDF-reader with hot-reloading and keyboard navigation, obviously inspired by https://github.com/pwmt/zathura but also cross-platform.
It's in a functional state, I use it myself but it needs some more ergonomic features before I'd suggest for someone else to use it.
Building an app to reverse geocode all the photos I've taken and screenshots of places I want to go from TikTok/Instagram.
Use cases are extracting the itineraries I took from prior trips, then using that to ground LLM search recommendations: I have a set of bookmarked places, say in NYC, can you make me a week of plans given what I enjoyed in Taipei?
I've been working on onsite deployments for https://www.keystash.io, which is a Linux SSH Key and User management system. It's been going for a while now and I am finally implementing onsite deployments as so many customers actually want to run this themselves. When we started, we really thought customers wouldn't want the hassle of another piece of infrastructure to manage, guess we were wrong :-)
Onsite deployment is a lot more difficult to make slick and easy. We've been thinking about the best way for our customers to deploy while reducing the load on our support team. So far, we are thinking about RPM's, Debs and Docker and trying to make this as close to a '5 step process' as possible.
I would love to hear people's thoughts on other mechanisms that make it easier for SRM's / DevOps to manage key platform infrastructure software.
I’m Moha from Somalia .
I’m building Cigaal, a super-ecosystem app that blends social media, commerce, payments, crypto rewards, and AI. Think of it as a lightweight alternative to WeChat, Grab, and Temu – but designed for underrepresented regions first.
Key Features: Marketplace + Delivery + Travel Booking
ZooCoin: our in-app crypto rewards system
AR shopping, short videos, stories, and chat
Cigaal ID: unified profile & wallet
A2A/B2A Agent Economy: agents handle cash deposits, deliveries, and API integrations with businesses
CoreIQ: an AI memory core that assists users across all Cigaal mini-apps (wallet, health, travel, shopping, etc.)
Why it matters: Cigaal helps bring modern digital experiences to places with limited infrastructure, enabling creators, travelers, small businesses, and buyers to thrive in a shared economy without being locked into Big Tech platforms.
Would love feedback, suggestions, or partnerships – especially from people building in fintech, agent networks, or AI-driven apps for underserved markets.
Site (coming soon): [cigaal.com]
A series of pulpy short stories, sort of a Dark Americana / weird fiction thing. Noir, magic, existential dread, horror. Warming up for a novel in a completely different genre but I wanted to iron out some of my own shortcomings and stretch some muscles before I write yet another 100k words on a project I'm unhappy with.
Working on Taskade (https://www.taskade.com), building the execution layer for AI collaboration.
Taskade started as a real-time workspace for teams to organize projects and ideas. It's evolved into something bigger — a platform where humans and AI work side by side.
We’re moving past simple chatbots into real agentic workflows, where teams can generate structured task lists, mind maps, and tables, train custom AI agents with dynamic knowledge, and automate work from start to finish.
Today, Taskade is built around three core pillars: Projects, Agents, and Automation. It’s like giving your team a second brain that can think, plan, and get work done across projects, automations, and real-time collaboration. If you’re interested in the future of human-AI collaboration, take a look!

Language learning app for intermediate learners who want to practice reading and listening:
- As you're reading, AI helps you with words it thinks you might not know
- Highlights etymologies & mnemonics
- Shows you words in their natural habitat, e.g. listen to example sentences
https://www.hellozenno.com/
I'm trying to read a kid's version of The Odyssey in Greek and to be able to understand my partner's mum, and these are the features that I wanted.
Also, I wanted to experiment with "what would an app like this look like if we could trust AI to be very cheap/fast/correct?".
- So, for example, it's a fully generative dictionary & search, e.g. the dictionary entries/metadata/example sentences don't exist until the first person searches for them!
- You can upload any kind of content (image, audio, text), and it'll automatically transcribe, translate, annotate, etc.
https://eval.16x.engineer/ - 16x Eval: A desktop GUI app to evaluate prompts and models

I made an electronic board game: https://github.com/seanboyce/Calculus-the-game
It's compatible with Settlers of Catan. However, I plan to make my own rulesets, artwork, manuals, etc. It will not be a commercial product, of course you can make your own with the files I provide.
Right now the boards, electronics, and firmware are in good working order. Although the routing is pretty YOLO.
It feels like there's a lot of unpleasantness going on in the world right now. I thought maybe I could put my other projects aside and try to make something that might brighten your day (It certainly has enough of LEDs).
A big TODO is to replace the 0402 SMT components with something larger and easier to work with like 0603. I'll find time within a week or so and push it to the repo. (I am notoriously cheap and only keep 0402 in stock)
A language learning app for couples (https://couplingcafe.com). I wanted to learn my wife's native language, so I've been building this on my own for a long time and testing solutions! Just a few paying happy users. Cooking up a lot of ideas

A social advocacy platform for small and medium sized B2B businesses. LinkedIn is more or less the only social platform for B2B social selling and smaller firms could benefit from their posts getting a bit more augmented and coordinated engagement. So we’re building a solution for a marketing manager to request advocates (employees, partners, others) to engage or reshare (tweaked in their own voice if they want) their content. Not world altering but shockingly underserved market. With few players who raised money and therefore have to price expensively, whereas as a bootstrapped side-hustle we can offer it in a flat-fee way that doesn’t “penalize” growth by charging per-user or for inactive users.
(Pre-launch [https://www.sevenbaton.com] would welcome feedback from marketing folks)
I'm working on creating a volume mixer, basically like Deej, but more polished.
Some things I'm planning on including: - App drag & drop for assignment. - Programmable macro buttons. - Small OLED displays to show app icon and volume levels.
Attempting to do everything in Rust too, even the MCU firmware. It's been a lot of fun. xD
I am working on making it easier to learn languages. We provide a platform for teachers and educators to create their own language courses. The platform offers features similar to software like Babel or Anki, along with some unique features for phonetics study and customizing the learning experience.
We're currently working with language influencers to build courses on Emurse. This year, we launched Japanese Phonetics course created by the YouTuber Dogen https://emurse.io/course/japanese-phonetics.
If you want to try out Emurse, we have a free Thai reading course available. You can view the first lesson without out creating an account: https://emurse.io/courses.
Working on specstory.com which today is an extension for Cursor & Github copilot that allows you to save, search, share your AI chat history.
Most AI first coding tools don't seem to respect how much critical context gets lost between sessions. Prompts, chats, refactors, decision paths all gone. Really believe that intent (prompts & responses from AI) is going to be the critical artifact upstream of code and there is a need to capture all of it: what the AI suggested, what you kept, what you rewrote, and why. We integrate directly with AI-powered IDEs so your intent becomes as searchable as your code.
We started with Cursor and just shipped support for GitHub Copilot (Agent Mode). The long-term goal is to build a canonical intent layer for codebases built with AI—something like git log/blame, but for why things changed, not just what.
For awhile I've been working on an MPE MIDI controller called the Mosaichord. It uses a tuning system called just intonation, where the frequencies of all the notes are related to each other by whole number ratios. I'm using a scale that has 28 notes per octave. Keys are pressure sensitive.
A few weeks ago I got a video of one of my friends playing it at a show: https://mastodon.social/@DesiderataSystems
Something I'm working on right now is trying to implement a basic on-board synthesizer so people can use it without a laptop or external hardware synth. (I added a DAC a couple hardware revisions back, I just haven't done anything interesting with it yet.)
The firmware is open source and there's a fairly detailed user manual.
Crypto, Fiat, AI Ecosystem
I'm working on a new kind of financial infrastructure that combines crypto, fiat, and AI to make managing money in decentralized environments simpler and smarter. The core idea is to move beyond the traditional 'wallet' model and instead help people, especially in emerging markets, make better, more informed financial decisions using real-time intelligence and automation.
It’s designed for everyday users, not just crypto-native folks, and it focuses on things like streamlining DeFi, improving transparency, and reducing user fatigue. We’re building with scalability and user experience in mind — something that actually fits into people’s daily financial lives, not just trading.
If you are very keen on working with me, I am building a team of devs too.
Let me know what you think of this idea.

Still cracking away CodeVideo, a way to create software educational content in a declarative manner. Design your course once, export it to every format you can think of (video, PDF, markdown, HTML, and more). I was recently inspired by the feature set I saw at Scrimba, so we just added slide functionality! The blog post is here: https://codevideo.substack.com/p/introducing-the-slide-displ...
And an example video is here: https://youtu.be/1duE604MGHs
It definitely has not gotten the traction I'd expected, but at the very least I'm very close to start making my own courses with it!
I'm building an interactive map based search interface for concerts and events in the bay area: http://fanflame.city/
This is something I've always wanted for myself so I decided to build it. Plenty of event aggregators out there, but not many that let you search and filter by any combination of locations, dates, and genres.
It currently supports automated data feeds from ticketmaster and the Civic Joy Fund; hoping to add Parks & Rec, Library events, and some other ticketing sites in the near future.
It has been a fun way to keep my coding skills sharp (Eng Director by day), I've learned a ton about react, mapbox, django, postgis, and GCP doing it. If you have an event source I should look into or a feature request let me know!
Recently I’ve pretty much replaced searching Yelp or TripAdvisor with a combination of Instagram Reels/TikToks and Google maps for travel and food recommendations. I usually just save a lot of places that I have to dig through and watch again to dig through and add to my saved Google maps lists. Because this takes me a fair bit of time when preparing for a trip, I decided to automate part of it by building a pipeline to “watch” the video for me by getting the audio and video frame data and taking into account key POIs that I then export out to a note. Later I plan to also integrate this with other travel or food tracking software like Wanderlog, Google maps list, or Beli eats. So far it’s been working well, but def expensive (so thank god for free GCP credits haha)
https://nuenki.app - a browser extension that translates sentences at your level while you browse, so you learn a language through immersion while you go about your day.
I'm also working on and off on a hardware device for blind people.
While Git is great at asynchronous collaboration, its a bit clunky to try and work on the same commit with other devs or across devices. This is because Git tracks what changed, not how it changed.
It'd be cool if you were on the same branch as somebody else, or another device, and your working directories could be synced. It'd also be cool for the commit history to be a bit richer, so you could see who, what and when for a change at a keystroke level.
So I'm working on real-time sync for Git! I'd represent the working directory as a tree CRDT [1] and sync that through FUSE and p2p networking.
Not sure whether this is actually a good idea! This is a POC :)

so I'm working on side project to make managing and exploring your music library easier.
The idea is you can set a few filters (like bpm, key, decade, genre) and then swipe through random songs, accept or reject them for inspiration or playlists. Kinda like Tinder but for digging through your own tracks.
It also tracks what's trending on TikTok/YouTube/SoundCloud weekly, so you can find stuff that’s blowing up, filterable by region. Plus it can build smart playlists automatically based on rules you set (like “new 90s house under 120bpm” every month).
It is just a tool to make working with your existing local/Apple/Spotify/SoundCloud library faster and more creative.
Here's a demo of it: https://filtered-f.web.app/

I'm trying to figure out how I can turn hobby products (that me and family and friends are using) into real products for a wider audience. So far, I've found 2 main failure cases:
1. While I can share source code and documentation with trustworthy people, that won't work at scale: the market would get flooded with Chinese clones that re-use my Open Source software but then I have no ongoing revenue to fund support / maintenance.
2. Especially for products with a physical component, shipping, taxes, refunds, CC chargebacks etc. add considerable overhead. Plus I need to add in Amazon fees and marketing spend. And suddenly I need to charge 8x the manufacturing price, which means I either need to massively cheapen out with quality, or it's going to be a very premium product.

A semantic music visualizer :) real-time capture of elements of music —- not tracks but true elements —- paired with time-stable frame generation for display. It likely won’t be as good as a real VJ, but I want to outshine all the visualizers which are basically a demo atop a grapheq.

I'm working on a Kaggle competition about predicting subsurface models - a map of the geologic layers beneath a given area - from seismic data.
I don't expect to place competitively but I learn a lot from these competitions. I like competitions like this that are connected to physical problems and datasets (though sadly this one is largely simulated), I learn as much about the broader world as I do deep learning. I've always idly wondered how seismology worked, and now I have an excuse to dig into it.
It's also given me a greater appreciation for the "seismology" we perform in our day to day, like knocking on things to see if they're hollow, or (as I learned here a while back) the way battitores test the porosity of cheese by knocking on it with hammers.

A children's book about creative problem solving and entrepreneurship.
The book is written in the Choose Your Own Adventure style. Readers get to join the protagonist Daphne on a fun, week-long adventure launching her own mini-businesses. Readers help her make smart decisions, solve fun challenges, and learn about money and problem-solving in the process.
The book has been a fun endeavor in both writing the manuscript and code! On the latter, I wrote an exporter for Twinery to Org Mode and an Emacs Org export backend to do the reverse.
The book is currently open to beta readers - Happy to let a few more in through the sign up page here: https://tendollaradventure.com/#get-notified
I am implementing a baremetal USB device stack in an embedded application and an having a really, really hard time. The device in question is a decoder for sportive chronometry and uses lots of DSP for detecting and measuring when vehicles pass through the finish line.
Just a small hardware project: I am building a cocktail mixer in an old PC case. I saw something similar at a con over Easter and had to build one myself, it had a tap coming out of the 3.5" bay and the ingredients were inside the pc case. It uses peristaltic pumps to move the different ingredients to the cup. It is very simple, but still took a couple of days to complete. In detail it consists of 6 x peristaltic pumps, 3 x L298N motor driver, 3 x PCF8574 io expander and an esp32. The software for the esp32 is very dumb and I actually coded it correctly before I had all the parts, it just enables and sets the speed for the motors and is attached via USB to a laptop. There a webapp is used to manage ingredients and recipes.

I am working on a PromptLibrary (https://promptlib.prashamhtrivedi.in/) to organise my prompts and make it accessible from multiple clients (Including chatbots (via chrome extensions), CLIs, IDE extensions amongst the few).
I wanted a library to store my own prompts once and retrieve it in multiple locations (i.e. Try something on claude desktop and then once I wrinkle out the edges, load it in Roo code or claude code and use it.) Give some variables to the prompt and creating infinite versions of same prompt by providing the value. Or having the versions of each prompt.
Currently I have the landing page, soon (In max 10 days) I will make it live for everyone to use.

MAGiE: Your MAGnetic Interactive Explorer
A simple puzzle game: a cassette-futuristic story, heavily inspired by Nell’s adventures at Castle Turing in Neal Stephenson’s “The Diamond Age”.

I’d love your feedback:
Rewind to the start of the story: https://magiegame.com/test/2025/04/04

I'm currently working on Academy Referral* (https://academyreferral.com). It's a referral platform for martial arts academies, allowing owners to reward their students for bringing in new members.
I've trained martial arts for a few years, and have always been that person who tries to introduce those close to me to the community. I know a lot of other people do the same.
Now, I don't care that I wasn't rewarded for it, but why not? We have point-based programs for nearly everything. Why not for martial arts as well?
* Have a few academies in the process of testing it out. Still a lot to do, including the demo video that isn't going to load on the main page.
Critic (https://getcritic.dev) - An improved inbox for GitHub pull requests
The experience with GitHub can be terribly frustrating when it comes to managing the stream of incoming pull requests. The default inbox and notification systems are not so good, and not flexible. Critic allows to create any number of sections, each section being defined by an arbitrary search query.
I would now like to expand it to provide a better code review experience, similar to what Graphite or Reviewable may provide - but under as an open source project. Source code is available at: https://github.com/pvcnt/critic
Working on a FOSS card game.
I realized after trying multiple tools like Supabase and Firebase, I really need to program my own solution. I don't need a bunch of *Enterprise* level features. I just need to read the card data from a database, and process the games with some simple server side code.
I hope to have the server, along with a basic front end done by this summer. Then it'll be released under a permissible license. Probably MIT.
I want a community of different front ends compatible with the same server. I suspect a straight up cli client without a bunch of effects might be popular with some of y'all.
If you want to code a frontend in Unreal, the server doesn't care. The game remains the same.
Of course your free to fork it privately, build a commerical product, etc.
I'm building an MVP for an "AI bedtime stories" app. The idea is that you just input the character names, a theme, and choose a voice (including the option to clone a parent's voice for narration). It generates a story and reads it out using TTS.
There are already a few services like this, but most don't support using a parent's voice, and very few can connect stories together into a continuous narrative based on previous ones. Also I would like to hold context for fairy tales kinda local. For example Polish folklore is different than British. Most common villains are different and it can be fun and educating problem to solve.
I'm mainly doing this as a learning project, but curious to see where it ends up.
I've been writing a software synthesizer, I want to use it to make an album when it's finished. As of now I've implemented a basic subtractive synth with the usual primitive oscillators, random noise, high and low pass filters, and an ADSR envelope. I've implemented input and output "drivers" for Windows and Linux: WASAPI, ALSA, Windows Raw Input, and evdev.
Soon I'll start work on Lua bindings. The idea is to configure the core engine programmatically. Hook up inputs, modify synth parameters, route output. It's going to be inferior in every way to something like SuperCollider, but I just think it'll be insanely cool to materialize music from thin air. I've learned lots.
I spent the weekend working on the Ansible automation needed to deploy Tomcat and Roller Weblogger for my new personal website/blog[1]. Once the loose ends are tied up with this, I plan to deactivate my Facebook account and mainly focus on the personal site + Fediverse sites for sharing stuff. This is both to be consistent with my principles, which say to disfavor closed-source / walled-garden sites like Facebook, and because it should free up some time I waste when I allow myself to get pulled into political discussions on FB. It'll probably be better for my mental health as well.

I'm working on an Ephemeral Markdown Paper: https://github.com/unvalley/ephe
If you’re tired of bloated to-do and note-taking apps, give this a try. It's OSS, free and No sign-up.
I’m working on Catchcam - https://hackaday.io/project/199220-catchcam-speed-camera-det..., a privacy-first, offline speed camera detector for drivers. Unlike apps like Waze or Radarbot, Catchcam doesn’t track your location or require an internet connection. Just plug it into your USB socket, and you’re good to go.
Key features:
• Built-in speaker and LED for alerts
• Preloaded with 66,000+ known speed camera locations (more to come)
• Easy updates via drag-and-drop on your PC
It’s been a fun project to build, and I’m excited to see it help drivers stay away from speeding tickets while keeping their data private.
I’d love to hear your thoughts or suggestions!
A custom Python/Django based mini-app (mini — at least for now) that will allow me to import transactions sanely and safely to my local GnuCash install.
I’ve been doing tedious manual entry for a bit over two years now and after having missed three consecutive months, the only other option was to bail.
As a start it should help with 3 main things:
- Translation, categorization: my source documents aren’t in English but my GnuCash entries are. This is one of the reasons I don’t use the built-in imports. (This should shave off at least 90% of time spent entering data)
- Human-error prevention: there were at least 5 times where it took me over 15 minutes to reconcile a discrepancy because I entered some number or some account wrong somewhere.
Working on redesigning my SaaS template. It uses Dokploy to deploy the NodeJS app, and Pocketbase instance within the same server, so DB reads and writes are very fast. Also doesn't use the Pocketbase client library at all, all calls are wrapped in their own API routes and everything is server side rendered.
You might ask why use Pocketbase at all, and I'm not sure anymore. I suppose the dashboard is great, built in auth is great (although I've had to write cookie middleware to make it SSR anyway). I wish there was a lightweight Pocketbase/Supabase style "backend in a box" setup that didn't push the whole client library directly communicating to DB paradigm.
I shared this last month as well but I’ve added a couple new features since then: a weekly digest email, a list of what you’re tracking and a price history chart.
I’ve been building https://lowlow.bot, it tracks price changes on any website. I was inspired by https://camelcamelcamel.com, but wanted something that worked for more than just Amazon. It’s been handy for big purchases I’m ok waiting for and stocking up on recurring non-perishable essentials when they go on sale. It also lets me know when something has come back in stock.

I have been working with a small team on a platform that allows luxury brokers to do due diligence on clients, ownership transfer and receive/issue payment all in one platform. We are pretty much merging the luxury retail market with banking.
Brokers (cars, planes, houses, boats, watches, etc) never have to worry about chargebacks, they get instant payment, free deposits and payment (compared to payment processors and marketplaces charging 2-10% per transaction).
We are currently onboarding luxury buyers, brokers, and brands you can check us out and apply to be part of the ecosystem. https://nezzapp.com

nice work
Thanks :)
I'm making some minor changes to my personal site/blog to improve contrast, have a more uniform usage of colours throughout, and also replacing "categories" with tags so that I can have related content easily linked and searchable.
I may also finally finish implementing WebMentions support too as a kind of comment section.
I may also work some more on my long-term relaxation/creative maze generation and solver project.
At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.
It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.
To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.
Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".
The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.
So I guess what I'm saying is I've been casually looking around at jobs this month.
This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.

I'm still mulling how to go about porting my tiling window manager for Windows[1] to another platform, or even if I'll do it at all. There is some demand, but I don't know if there is _enough_ demand
Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so

How does that guarantee that all participants are human?

I recently published this library for routing messages within an application using the same kind of wildcard semantics that NATS uses - https://www.npmjs.com/package/@gooseus/natsrun
Currently just test driving it in some relatively simple work scenarios, but I imagine it could be a useful tool for consuming a NATS firehose of messages in a single application and routing them internally using the same semantics subject rules so that it would be easy to split them out as separate consumers when/if that became necessary.

RedwoodSDK is a React Framework for Cloudflare. We wanted to build something that allows people to focus on the software that they want to write, rather than the infrastructure that it runs on. Writing software isn't really a barrier anymore, the parts that developers find annoying can be shortcut with generated code, but you can't gloss over pushing to production.
Cloudflare gives us the ability to offer developers compute, database, storage, queues, AI, realtime with durable objects, etc... and to emulate that locally with just a single package installation.
A standardized dictionary/lexicon for the variant of pidgin English that is spoken around Western-Africa.
https://yarnz.app/
It contains words and phrases with their accompanying context.
This is really cool. Do you speak this pidgin or are you trying to document it as a non-native?
Thank you! Yes, I'm from Nigeria. I became interested in this when I met people from other West African countries and learned that they speak the same type pidgin with tiny variations.
Building an IP Geolocation guessing game: https://abdullahdevrel.github.io/ipguessr/
Let me know if you have any feedback or feature requests.
Very interesting idea. Are those IPs real? Where are you getting these from?
I appreciate you enjoying the game! I work for IPinfo but initially made it as a sort of meme for our users.
I'm generating random IP addresses on the frontend, then making an call to our free API to validate the "realness" of the IP addresses — mainly to remove bogon IP addresses, non-routable IPs, and IPs from large ASNs (national ISPs, the DoD, car companies, etc.).
Our free API supports 1,000 requests per day from unique IP addresses, so there shouldn't be any issues for low usage. However, if we get more power users who enjoy the game, I’ll switch to our Lite API service (which is also free, https://ipinfo.io/lite) to validate IP addresses, as it supports unlimited requests.
Let me know if you have any feedback for me :) I made it mostly by "vibe coding", I will write a post about the whole process of it.
You can download data sets from Maxmind.
I work for IPinfo — I described my process of how I made the game in the other comment.
Using a dataset-based implementation would require me to have a backend, which is out of the scope of this project. Right now, I'm generating random IPv4 addresses, but if I were generating random IPv6 addresses, I would have to go the database route. For that, I would use our free IPinfo Lite dataset: https://ipinfo.io/lite
My colleagues actually developed an extremely fast algorithm to select truly random IPv6 IPs from a series of CIDRs, which is what you see reflected in our dataset.
Let me know if you have any feedback or suggestions for me, please.
I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the tool will run everything in parallel while caching as much as possible.
Why should I use this and how is it better than Bazel?
If you are a small to mid-sized team, moving to Bazel is massively painful and basically requires up to one full-time position to provide your team with a good experience.
Grog on the other hand let's you keep your existing build setup while just parallelizing and caching it. It's not a full replacement, but it's more than enough for most mid-sized teams that want to have fast mono-repo builds.
Working on a web app builder that generates code via AI, much like hundreds of other tools out there. The differentiator is that the tool automatically sets up a Postgres DB (using Neon) for you. So, it's a lot easier to get started and it can handle large complex apps that require auth and database, but it can also build simple websites. The stack is next.js and code is easy to export and view.
Primarily uses Claude Sonnet 3.7 and Gemini Pro 2.5. But you can choose other models too.
You can try it for free while I'm beta testing it here: https://lumosbuilder.com?ref=hn
This is awesome. My name is David and I work at Neon btw. Email me through david@ if you want to chat!
Still working on https://theretowhere.com since I announced it to HN in February.
It's an website who's goal is to make it easier to find apartments/hotels/etc that fit your housing preferences (starting with places that are close to the people and things you care about). It's flagship feature is the ability to make heatmaps of cities based on your preferences.
Since February I've slowed down on feature development temporarily as I try and find a way to sustainably increase it's popularity and learn what's the most important thing to focus on next.
https://github.com/datalpia/laketower
Slowly building an open-source Data Lakehouse management utility application for local development, scratching my own itch and trying to accelerate development workflows with customers developing for Databricks.
For now it only supports Delta Lake (using delta-rs + duckdb), only supports table metadata inspection and querying, but in the near future will add dashboards as code, simple Markdown notebook like mode, and Apache Iceberg support.
For now it's an enabler for me and others, hopefully I can turn it into a product somehow at some point.

I’m developing a VS Code and Cursor extension that helps developers quickly copy all code in a workspace to the clipboard for use with LLMs.
It also displays the token count for each file, as well as the total token count across the workspace.
By default, it ignores files listed in .gitignore, but this behavior can be customized in the extension settings, along with many other options.
I am working on a direct competitor to Netsuite. I’ve worked on ERPs, accounting, and inventory long enough to think I can do it. And with AI I can make progress on this in a way that would have been unfathomable a year ago.

Lighthouse (https://lighthouseapp.io/) - a different take on RSS readers, focusing on inbox zero
RSS readers show content based on the feed they're coming from, and show read and unread items in the same list. That makes it difficult to know which items you've already seen, and is especially annoying for managing items that you want to read at some point but not anytime soon.
Lighthouse splits it into Inbox (new items) and Library (bookmarked items). This makes it possible to process new items quickly, and take your time with reading them.
For a more data science-y project, I'm having a blast building https://nhlforecasts.com. I live in a town with a hockey team, and figured the best way to become a fan would be to understand the sport from a data driven approach.
I did a ton of work on building an Elo model first, but was getting very compressed results in terms of postseason predictions. I swapped to a Bayesian approach which has really taken off. Not sure how it's going to handle the second round of games approaching, but that's a problem for the future!
I'm working on Proflect — a personal and professional growth platform that connects goals, journaling, and feedback into one flow. To help you grow by reflection, not just action.
The idea is that growth becomes a lot more intentional when you can reflect daily, set goals clearly, and get structured input from people you trust — all in one place instead of scattered across different tools.
I'm getting ready to open early access soon. Curious if others have tried combining these areas or if you use separate tools for goals, journaling, and feedback!

Working on supporting MCP (model context protocol) in my LSP (language server protocol) proxy: https://github.com/noredeen/lspwatch.
I wrote this tool to make instrumenting language servers very easy. MCP (both protocol and architecture) seems heavily inspired by LSP which made me curious about what it would take to support it through my telemetry-capturing proxy.
Haven't thought too deeply about how useful an MCP proxy can be but I see it as potentially a general platform for monitoring or debugging MCP servers or clients.
Super interesting! I'm also working on something related to MCP and LSP: https://github.com/isaacphi/mcp-language-server it's an MCP server that runs a language server.
Do I understand this properly, you're building a telemetry tool for MCP similar to your telemetry tool for LSP, or is it something else?
Yup exactly. My tool is supposed to sit between MCP clients and servers. For now only stdio is in scope. Your tool is great. An MCP server for LSPs! I'll be taking it for a spin.
Schematic and PCB design relating to Lighting and Control Systems for my main job. Schematics and PCB Design after hours as a contractor too, because I have a daughter now, my wife can't work, and life has become /very/ expensive in Sydney.
What I'd love to be working on: Try to initiate a high voltage arc through the air to a target device, and modulate it to send "Data over Lightning", like Alyx does in Half-Life 2. It won't work the way it does in the game, but I'd it's an idea I've had for a long time and I'd love to prototype it some day.
I'm working on a mobile app for exploring places with Wikivoyage (https://mapvoyage.app) and a wikitext to structured JSON-tree parser to support that (https://github.com/bcye/structured-wikivoyage-exports) and am finally getting pretty close to a beta version :) I hope to unify the workflow of going back and forth between Wikivoyage, the favourites list on Google Maps and notes into a single app.
A new way to type on gamepads designed around the hardware rather than trying to fit gamepad input to a qwerty keyboard.
I’ve been working on it for a few months and I’m hoping to have a demo up at 7:00 PST today for HN to play with :)
I'm working on a workflow automation tool that lets devs write workflows in simple yaml files, and then deploy them to the cloud _or_ on premise. Each workflow is a set of actions and a trigger that can transform data, make api calls, run AI models, or really anything (via docker!). Each step relies on the output of the last step, and the workflow framework is engineering to be declarative, testable, and versioned. Similar to GitHub actions, but for *anything*. Think webhook to slack, email to support ticket, nightly aws backup & restore, mirror a file each night, etc.
premises, not premise :-)
Thank you! Learned something new.

Since my third year in medical school, I've built the largest medical education platform in MENAP. 90k+ users, 100m+ questions solved, billions of seconds spent learning across our Super App. Now working on sustainably scaling further, building medGPT.
It's awesome, exciting and impactful work. I am the first medical doctor + full stack technologist in Pakistan (250m) people, and we've helped the country move medical education decades forward.
Are you aware of anything similar for vets, or would there be interest in building this?
Part of my vision is to also help revolutionize adjacent healthcare fields, as we're focused on premed, medical and dental currently for undergrads + recent medical graduates, but nursing, pharmacy, physiotherapy and veterinary school all are of great interest to me. I am a big animal lover personally.
For such markets, you can imagine that the TAM etc is smaller, but still important. For us it's a blend of mission driven and business.
Thanks for the comment! I would love to chat vet-ed-tech further, I am on LinkedIn (/in/az1b) or email: azib [at] az1b [dot] com

I find tracking movies and series I have watched with my partner an impossible task. Spreadsheets are too fiddly for my partner, and I want to look up what is next on my phone so I have turned to Airtable and n8n for automation.
input a relevant url, it will decide if it IMDB or Youtube or a list. using an llm, it will attempt to extract the movies or series from the list and find the relevant IMDB link.
Then I have a masonry view of movies & series I have and have not watched, sortable by tags that I can rate and add notes to.
Tried justwatch.com for this?

I built a tool to help hiring managers scan and categorize resumes against a job description: https://app.joinrunway.io/rank/create.
It gives you a ranked list so you can quickly spot the strongest candidates, or at least get a solid starting point without reading every resume manually.
It scores applicants based on job requirements, flags any concerns, and suggests interview questions you might want to ask.

I'm working on a multicast dns implementation in OCaml. It's a library allowing one to build custom queries/responders, plus a conventional querier that can be used as a stub resolver for .local to get the resolver functionality of avahi.
My main motivation was to implement a service that publishes the addresses of containers and vms that I run on my workstation to my local network, but it gradually has grown into a full-blown implementation of RFC 6762, which has been fun.
After struggling with bloated, ad-filled debugging tools, I decided to build MyDebugTools—an open-source, clean, and ad-free debugging tool.

Basically a test of putting guard rails around format and content of a website and seeing how much I could automatically generate on a topic of interest to myself.
Biggest benefit I've seen with cursor is to write tests for everything. Far too mcuh content hallucination, or made up links at first, but once you put in some test guardrails you can minimise this.

I'm about to wrap up the alpha release of an Rust/Tauri based GUI desktop app that allows me (and others if interested) build modular AI agents. At this point it gives you control over the system prompt, LLM, message and which MCP tooling you want to use (to prevent cluttering the request with 69 unnecessary tools you do not need anyway). You can store agents as templates, so you can reuse them with ease.

Exploring MCP (model context protocol) using Claude as a base LLM. I understand that this is quite new and may change a lot in the next few months but I feel something interesting could be done by plugging transactional APIs to a LLM.

This kind of hack can lead LLMs to be the 21st century browsers.

In little bits of free time I get here and there, I've been working on using reinforcement learning to build some better bots for my favorite multiplayer game. Project is up here: https://github.com/cgadski/autotude
So far all my work has gone into the technical side of setting up the game (a Java app written in 2010) to work as a reinforcement learning environment. The developers were nice enough to maintain the source and open it to the community, so I patched the client/server to be controllable through protobuf messages. So far, I can:
- Record games between humans. I also wrote a kind of janky replay viewer [1] that probably only makes sense to people who play the game already. (Before, the game didn't have any recording feature.)
- Define bots with pytorch/python and run them in offline training mode. (The game runs relatively quickly, like 8 gameplay minutes / realtime second.)
- Run my python-defined bots online versus human players. (Just managed to get this working today.)
It took a bunch of messing around with the Java source to get this far, and I haven't even really started on the reinforcement learning part yet. Hopefully I can start on that soon.
This game (https://planeball.com) is really unique, and I'm excited to produce a reinforcement learning environment that other people can play with easily. Thinking about how you might build bots for this game was one of the problems that made me interested in artificial intelligence 8 years ago. The controls/mechanics are pretty simple and it's relatively easy to make bots that beat new players---basically just don't crash into obstacles, don't stall out, conserve your energy, and shoot when you will deal damage---but good human players do a lot of complicated intuitive decision-making.
[1] http://altistats.com/viewer/?f=4b020f28-af0b-4aa0-96be-a73f0... (Press h for help on controls. Planes will "jump around" when they're not close to the objective---the server sends limited information on planes that are outside the field of vision of the client, but my recording viewer displays the whole map.)
OkNext! (https://oknext.io) - a task manager for solopreneurs and small teams.
I'd love for you to try it out! It is browser based only for now and pretty basic. I'm adding features sparingly as needed but my next task is to add some documentation for brand new users and making what it can already do more obvious.

Honestly a little bit hesitant to say anything yet. There are a few more features to add, and a whole lot more work to be done to showcase just how cool it is. But the short version is, I'm working on a sort of meta-pico8, a game maker for WebGL2 2d pixel art games (e.g. 320x180 games like Animal Well) that runs in the browser, but one that's firstly collaborative, so that we can all build it together. And some of the coolest features are the based around that. For example, I got arbitrary imports of user code working in the browser, so all you have to do is create an account, add a JS file, and other people can import it as if it were a built-in module, and it just works. Plus the SDK I ended up making is simple, and the API is clean, and there's a few innovations in the GUI layer that I'm excited to share. I wish I could explain just how cool this is.
Interesting, I have been working on a similar project, albeit 320x240.
I also got some code-share and collaboration features working, but got a bit stuck on fonts. But I can appreciate your feeling of 'how cool this is'
I ground to a halt once I realised I had no barrier to entry, ie it could be cloned very easily. Always an issue with Web Development I guess. Plus I hate what modern browsers have become in recent years and not sure I want to target such a fast moving platform. I got burned once already with WebStart 'warning this app might do something scary' and certificate fiasco.
I thought about some native binaries, but I know I am kidding myself. I had an ios app that was pixel cloned within 6 months. But somehow a web app feels like publishing straight into public domain.
It's not just the web, native apps have always had free open source clones that technically render them useless, often just as good quality, yet they didn't go out of business. There are other considerations people make when deciding to use an app, including network effect, a strong community, sheer level of quality and passion from the developers, etc.
For fonts, I just went with a simple raster bitmap font and pixel grid storage format. Creating these limitations makes it easier for me and for developers and artists. I choose 320x180 because it fits the 16:9 perfectly, which would make full screen ideal on most monitors.

An email-based service to mail your photos as postcards. As a parent of littles: the littles love the postcards, and the grandparents love them too.

I’m working on https://vimgolf.ai, to help me learn new vim commands and in doing so hopefully help others. Right now, still working on adding the ai assisted level creation for each motion, but more to come on that.
One suggestion: please consider allowing custom key mappings. I use a Colemak-DH layout, so I remap HJKL and other VIM keys to more ergonomic positions. Tools like Vimium support this, and it’d really help with accessibility for non-QWERTY users.
Thanks for the feedback. I’ll see if I can add this into the plugin for neovim I use.
Is it possible to add an interactive challenge or two on the homepage prior to sign up? I think that would hook people in and make them want to sign up.
Good idea, currently I spin up a 2 neovim instances for each challenge, so can only spin up so many at once with my current setup. But, am moving to a kubernetes setup where I can scale up and down the number of neovim instances more reliably and will add that in then.
Ah, I assumed it would be an nvim JS clone running client side. Had you looked into that route?
I have, but all the JS vim clones are emulations of vim, and don't support all the vim motions (like copying from registers, etc). I honestly could do that and it would be easier, but doing it this way, also allows me to record the keystrokes directly from the neovim runtime.

I'm preparing my t-shirt store for launch soon.
I was having trouble meeting people after moving to a new city so I designed and printed some goofy funny t-shirts for my wardrobe, and that has really helped on getting the ball rolling on conversations.
Hoping to make the launch within the next few weeks.
What are some examples? I'd love to check out your store but I'm worried by the time you launch this post and any communication with you will have vanished to the ether.

pile - a framework & cli for managing a large number of docker-compose files running on the same machine.
Inspired by a pile-of-poo SOA application where essentially every service was dependent other services such that the entire app stack needed to be run in order for any 1 service to work.
In addition to organizing the array of docker-compose files, which may live in different directories, i also add some helper functions to bring clarity to the usual docker cli output. Ugly "docker ps" output can be gathered by using pile ports, pile commands, & pile state - all of which output what you think they do, but in a way that is actually legible and useful when running 20+ containers locally.

I'm working on a desktop-based, performance- and privacy-first note-taking app that lets you quickly capture notes from any selected text using hotkeys.
I'm curious: what are your must-haves in a note-taking application?
I thought about doing something similar some time ago, because I never quite found the perfect note taking app for myself. There's a million ways how to do notes, and it feels like there's just as many different notes apps.
Eventually, I've settled with Obsidian because of its simplicity and extensibility. You can leave it with basic features and truly own your notes in a simple format (you can also put them into any cloud, as long as that cloud reaches your filesystem). It doesn't do everything just like I'd want to, but I've thought about just building another notes app that reads and writes to the same path your Obsidian notes are in, instead of trying to cover every possible editing feature like most big notes apps. Then I'd use different apps for different needs, with one place to store data.
Since you're focusing on privacy, have you considered using Obsidian? Is there anything particular you want to do differently?
Basically I want to build it with focus on speed and work efficiency from start. To not bias myself too much, I will refrain from doing too much market research. First of all I'm building this for myself, and I'm guessing it might translate into at least a tiny market share.
> I'm curious: what are your must-haves in a note-taking application?
Unlimited undos. Even if I deleted text a year ago, app must bring it back. Ideally something like git, with branches and auto-commits.

There is still a lot to do and learn (especially in the marketing department), but we have plans for a new product in the privacy space. I don't want to say too much about it until we've started working on it, but it's in the compliance space and fits quite well with our existing product. I think it's always a good starting point to solve your own problems.
