Rumix
Multiplayer AI for engineering teams
What it does
Rumix turns a solo Claude Code session into a real multiplayer workspace, with live file collaboration, role-based permissions, and one join code to bring anyone in. Your coding agent, shared with your team.
Share a join code and whoever is awake picks up exactly where the last person stopped, with the same context, files and history. Nobody explains the problem to the agent twice. The agent, the files and the permissions are all shared. Everything below is enforced on the server, not suggested by the client. Owners, editors and viewers, with per-path rules. A viewer cannot read what you withheld, however they ask. Browse and edit the same working tree, and see who is in a file before you open it. Mention @claude in team chat for a read-only answer. Whoever's turn is running keeps running. Pick the CLI per session. The session outlives whichever you chose. Rumix runs the real Claude Code and…from rumixai.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.
