Cuukit Screen Lid
Keep your AI agents running while you step away
What it does
You start something long — an agent working through a task, a build, a render — and then you cannot leave the desk. Lock the Mac and the screen goes with it: Chrome marks every tab hidden, so work that depends on a page still rendering slows or stops. Leave it unlocked and the room reads your work. Cuukit covers every display behind a 4-digit PIN instead. What was running underneath carries on, the Mac stays awake, and only the PIN gets through. Free, Apple silicon, no account, no network.
A macOS menu bar app that covers every display behind a 4-digit PIN while your agents, builds and renders keep running underneath.
One click covers every connected display behind a four-digit PIN and holds the Mac awake for exactly as long as the cover is up. Whatever is running underneath keeps running. version 2.2.10 · 107 MB · Apple silicon · macOS 12+ signed and notarized by Apple · free, no account sha256 bcafa0f36c8ed0f2d62cc364f213a892b2a90918b1bfedae6851546a2ff9d018 The run does not pause. It is still moving behind the cover. You can, and you should when what you need is security. Control-Command-Q gives you the real macOS login window, which is a stronger boundary than anything Cuukit draws. What locking does not give you is a promise that the Mac stays awake. macOS offers to keep it running with the display…from cuukit.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.
