I recently retired after 37 years of working in tech so of course I am working on open source. My retirement treat was to spend three months learning OpenGL and 3D game programming by porting a classic Java RTS game, Tribal Trouble, to more modern OpenGL and Java. I learn much better working with real code and this was a great experience. It was certainly a different experience than it would have been without an LLM…

Excellent work on Tribal Trouble. I'm a huge Java fan and I had no idea this existed (usually you only hear about Minecraft and RuneScape). I wonder how much OpenGL/LWJGL code there is. It could maybe run in the browser with CheerpJ or TeaVM if that code could be ported to WebGL.

My labor of love is SnapCode: https://reportmill.com/SnapCode . It has a small interface (camera + vertex buffer) that can run on either desktop or in browser.

This would also be a great candidate for JDeploy (https://jdeploy.com), too, to provide a nice download package for multiple platforms.

I'm deep in the rabbit hole of ergonomic keyboards and working on the design of a wireless, 36-key keyboard that can be used as a unibody or split. This came about because while I enjoy using a split when I'm at a desk, I found it cumbersome to use when I'm moving around at a coworking space or cafe, or even while working on a couch, where a unibody keyboard is more convenient (albeit with less ideal ergonomics).

Normally, split keyboards use two microcontrollers and batteries (one for each half), but this design uses a single microcontroller and a GPIO expander to bridge the two halves together via a magnetic 4-pin connector. It also features a reversible PCB to further keep the overall costs low.

Just finished bringing up the PCBs and putting the ZMK firmware together. Still designing the case for it, but all the files are open-source and on GitHub!

https://kavla.dev/ It's an infinite canvas that runs SQL. I've been working with data my entire career. I feel like we need to alt+tab so much. What if we just put it all on a canvas? Currently very WIP, but there's a simple titanic demo available! Built with tldraw and duckdb wasm, running on cloudflare durable objects

Really interesting idea! I've only seen stuff like that in ETL pipelines (which are a pain). This sits somehow between a python notebook and a ETL pipeline.

By the way, I just shared in my company's Slack and looks like there is no opengraph data for it. Not a complain, just pointing out in case you didn't notice/think of it :)

Best of luck!

I’m the developer of Connective, kind of social app, but built with the idea of meeting people in real life, just a minimum of online interaction.

You can organize or join others reunions and share the same interests.

Is available for both, iOS and Android. Check out this web: www.connective-app.com

Please let me know what you think

I am currently building an agentic process to help me with social media marketing for my apps, as this is my biggest obstacle in terms of gaining traction. This involves disparate processes: AN entire workflow to generate high-quality blogs that are germane to my product domain, crafting posts on X/replies to comments in a tone that is uniquely mine, conducting one-on-one outreach on my behalf, etc..

I recently released what I think is an incredibly fun brain training app. It's heavy on toilet humor, but the goal is to improve your working memory, processing speed, and mental math. It's called Turd Turf and it's completely free to play- you can check it out here: https://turdturf.app

Working on the Mecha Comet ( https://mecha.so/comet ), a modular handheld Linux computer. Biggest challenges: - How to explain the different use-cases/possibilities in a clear way - DX for any hacker who comes across the device with/without hardware experience

Good idea. I like the idea of:

- having a handheld that moves away from Android, but can also be used as a phone on-demand. That is, being able to turn off the telco signal. https://news.ycombinator.com/item?id=46700907

- having a handheld that can be used as a barcode scanner. https://news.ycombinator.com/item?id=46879780

- having a crypto wallet with a "kill switch" in the event of coercive standover. Could also have a surveillance switch as well. eg see Mockingjay in this thread.

"for the geeks, by the geeks and of the geeks"

Really it should/could be for the plebs and anyone with a half a brain.

Developing LogiModel AI ( https://www.logimodel.com/ ) which is an agentic supply chain optimization engine that forecasts demand, optimizes operations, and simulates scenarios to reduce costs while keeping your network reliable and customers satisfied. It integrates seamlessly with your ERP and document repositories to learn your business context, then acts as an intelligent decision engine, freeing you to focus on…

Big market. Good luck with that. How will it be hosted? Who will implement it?

Would you follow the Red Hat business model? https://gemini.google.com/share/2825b8ff67d6

Part open / part paid closed-source? Fully open and charge on consulting/customization?

How will you stop LLMs from recreating it?

I've been working on Renderling — an open-source, GPU-driven real-time renderer in Rust targeting both native and web (via WebGPU).

I just signed a Memorandum of Understanding with NLnet (NGI0 Commons Fund) for a second year of funding to build out the Renderling ecosystem. The big shift this year: moving away from Rust-GPU and going all-in on WGSL.

I'm building wgsl-rs, a proc macro crate that lets you write WGSL shaders in a subset of Rust — same code runs on the CPU for testing and on the GPU via generated WGSL. Works on stable Rust, no custom toolchains needed.

The funded roadmap also includes podecs, a GPU-accelerated ECS where systems run as compute shaders, a Rend3-compatible API layer (for folks looking for a path forward from Rend3), and ultimately real-time global illumination via a GPU ray tracer.

More details in the latest news update: https://renderling.xyz/news/index.html#wed-11-feb-2026

Working on a knife steel comparison database. It lets you visually compare steels across key performance axes — edge retention, corrosion resistance, toughness, and ease of sharpening — using interactive radar charts.

You can filter by use case (EDC favorites, budget-friendly, high edge retention, etc.) and get a quick read on tradeoffs between steels like S35VN, MagnaCut, M390, and others.

Built it because I kept seeing the same "which steel is best" debates in knife forums with no good way to actually compare data side by side. Site: https://new.knife.day/blog/knife-steel-comparisons/all https://new.knife.day/steels
