What it does
extctl is a super simple systemd-sysext wrapper for signing and installing system extensions on a running Linux machine. It wraps the raw veritysetup / openssl / install / refresh incantations into a single command with a docker-like feel. extctl is a super simple systemd-sysext wrapper. It runs on any distro with systemd-sysext , veritysetup , openssl , and mkfs.erofs , and is not tied to any particular distribution. $ sudo extctl keygen # one-time setup; like `docker login` $ extctl init mytool # scaffold ./mytool/ + manifest $ $EDITOR mytool/usr/bin/ * # drop your tool in $ extctl build mytool # package -> mytool.raw $ extctl sign mytool.raw # sign (uses the keygen'd key) $ sudo extctl…from github.com

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
