Last Human Message
Pay $2 to unlock a message from a complete stranger.
What it does
What if $2 could show you a message from a complete stranger? This is a simple social experiment built around curiosity. Pay $2, and you’ll unlock the message left by the person before you. Then, you can leave your own message for the next curious person. No complicated features, no endless scrolling—just a chain of strangers, one message at a time. What will the person before you have to say? And what will you leave behind for the person after you?

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.
