LiveCoder is a fun tool I built almost a year ago to simulate live coding Frontend technologies for my presentations. You actually don't have to live-code, but just prepare beforehand the program, snippets of HTML, CSS and Javascript and you feed the tool with it, so you can just focus on explaining what's being coded. Simple :-) I never really shared this tool, but I used it in a few presentations quite succesfully, so I think it could be an interesting tool to use. You have full control of the speed. You can pause and resume... An entire app can be live-coded with this. It's quite fun to…

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.
