  SocialFolders, "Dropbox for social"2012 · ▲187

  Hey fellow HN-ers, I'd like to ask HN about my latest startup: SocialFolders. We take a Dropbox-like approach to managing your content on your social networks by mirroring all the content you have on these networks in folders on your computer. Moving this content around, between folders or between services, is mirrored in the all-mighty "cloud" (ugh, I hate this word). We'd love to know what you think. We think our approach solves the problem of managing content at scale. We put together a quick 2'30 screencast to show HN how it works: http://www.youtube.com/watch?v=4s2TFsVezZQ If you want…

  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.
