DevTools by Hakeemify

What it does

16 developer tools in one fast, ad-free tab: RegexLab, JSONCraft (TypeScript/Zod/CSV export), CronBuilder, JWT Decoder, APITester, ColorSystemPro, SQL Formatter, YAML⇄JSON, and more. The privacy-sensitive ones (hashing, JWT) run entirely in your browser — nothing hits a server. Start free, no account. Instead of another subscription, it's a one-time $79 lifetime, with first-class support for local payment methods so devs outside the US card system aren't locked out.

  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.
