Caffeinate — Keep Screen Awake
One click keeps your screen awake, with a built-in timer
What it does
Stops your screen sleeping — click once, that's it. Pick 30m, 1h, 2h, 4h, or forever; the toolbar badge counts down what's left. Most keep-awake extensions fake it with a hidden looping video. Caffeinate uses the chrome.power API, so it works after the popup closes and the tab loses focus — where wakeLock dies. Timers use chrome.alarms and survive browser restarts. "Keep screen lit" holds the display on, not just the system. No account, no data collected.

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.
