Dropping SynthID from 188/192 to 0/192 without changing visible text

What it does

F*ckMark is an open research instrument for constrained text transforms. Visible words never change. Releases are checksummed. MIT licensed.

F*ckMark studies statistical text watermarks under a hard rule: visible characters never change. One command. Checksummed GitHub Releases. MIT licensed. Installs the latest GitHub Release after SHA-256 verification. Python 3.11+. Most research tools look like a lab bench. Mark is a CLI with a product contract: if a transform would change what a person can read, it does not ship. Context survives. Evidence remains. User-visible text is the product. The public CLI fail-closes rather than rewrite a sentence. The one-liner pulls a tagged GitHub Release and checks it against SHA256SUMS before it ever touches your path. Source, spec, and confirmatory keys as hashes — not secrets — live in the…from mark.q1z.org

  Simple algorithm and color space to generate diverse skin tones▲627

  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 model to autocomplete piano on-device▲598

  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.
