ContaShare

What it does

Update your address, phone, or name once. Every connected organisation gets it automatically — no more filling in the same form for the council, bank, and broadband provider separately. For businesses: address verification that's usually a one-off snapshot, gone stale the next day. ContaShare makes it live — webhooks fire the instant a customer's details change. Free for individuals. 50 free API credits for businesses, no card required.

Store your address, phone number and name once on ContaShare. Share securely with any company via OAuth. When your details change, every connected organisation updates automatically. UK businesses get 50 free API credits on signup (~25 address lookups).

  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.
