The Calculator app for LisaGUI. I'm using high precision fixed point arithmetic to do the calculations. It's gonna have the same functionality as the original, with three different modes and a toggle-able paper tape. The Lisa's manual has been surprisingly helpful.

#252Upgrading to new version 2.0.0 of dnsdist using nghttp2 instead of h2o
It's never easy for me to compile this monster
Static-PIE binary with minimum options is a whopping 15M
It just keeps growing

#253I spent good amount of my summer holiday rebuilding Masterlist (https://masterlist.fi)
This is probably third (or fourth) incarnation of the app and I like writing a web apps with Hotwire more and more. Especially leaning more on features removes frontend complexity compared previous versions. Highly recommended, both Hotwire and rewriting your apps!

#254I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy. https://github.com/scallyw4g/bonsai I also wrote a metaprogramming…
Hey, I had a quick look at your engine's github page, what are you looking to do with surface meshing exactly?

#256My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…
Very interesting idea! I wonder if a political campaign one day will be to start a program that eradicates mosquitos via drone fleets, not just in the context of malaria protection but also in just nuisance reduction. There are similar programs in place in certain metro areas that already do mosquito control (using chemicals of varying toxicity), so it's not as wild of an idea as it probably sounds. My friend once ca…
Yeah, it’s one of our goal to work for government agencies at some point to implement city-wide mosquito control. 10 of our drones could cover a square kilometer, so we’d be a lot more efficient working at the city level rather than at the individual household level.

#257Working on a complex AI system that will eventually allow AI overseer subagents to create complex workflows internally on the fly for multi step reasoning capabilities. Its a vey complex system but easiest way I can describe it as a metacognitive framework for self organizing workflows depending on context and dynamic adjustment capabilities depending on environmental signals. lots of cool little systems that will do all types of fun stuff like feed logprobs to various Ai subagents to give extra bias signals or have the llms understand their own confidence in answering this or that query. Anyways I could write a whole decertation on all the various goodies in it. But currently at the moment starting small and working on developing automated hyperparameter reasoning evaluation system. its important to know the most affective hyperparameters per model and no better way to converge on those numbers then an automated system. After that using dspy or my own home brwe system to do same on converging for "best" system prompts for various tasks. And then setting up the various mcp servers that give these abilities to whatever llm uses them. Lots of work, but learning a lot in the process plus I love RND. I see potential in modern day systems for recursive self improvement just have to set up the system around the capability. thats the hard part, the vision is always easy...

#260I'm working on an open source wrapper and MCP server to give Claude Code voice capabilities (and Slack and WhatsApp messaging). It works with system default TTS and google free ASR on Mac out the box but allows you to BYOK to your favorite TTS/ASR provider. I've also tried to make it a viable python library to make it easy to switch between ASR/TTS providers.
With Claude Code I really like being able to multi-task but right now it's a bit like a Tesla on autopilot needing your hands still on the wheel. With TalkiTo I can do housework/go out for lunch and keep it on the right track remotely.
