- SCSwap contacts by scanning QR codes on your phone2012 · ▲5
We recently developed a way to get rid of paper business cards and their shortcomings (e.g.: clutter). It's called Napkkin (www.napkkin.com), and it lets you create a business card on your phone and swap it with people you meet by scanning a QR Code. You can get referred by your new contacts and get notified in real-time so you can track who's helping you with word-of-mouth referrals. We've got mobile/desktop web apps and Android/iPhone native apps set up. We're looking for feedback, so let us know what you think!

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.

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.
