What it does
An iOS network debugger for capturing and inspecting HTTP(S), WebSocket, and SSE traffic at L3 IP layer.
An iOS network debugger for capturing and inspecting HTTP(S), WebSocket, and SSE traffic at L3 IP layer. Perfect for iOS developers debugging API calls, security researchers analyzing app behavior, or anyone who needs deep insight into mobile network traffic. Comprehensive network visibility with the tools you need to diagnose and resolve issues fast. Network Extension-based packet tunnel configures a system proxy to capture HTTP(S) for apps that honor it. No per-app setup, no desktop companion required. On-device MITM with dynamic certificate generation. Full request/response body visibility for encrypted traffic. Real-time frame-by-frame capture of WebSocket and Server-Sent Events with…from trace.justinl.site

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-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.
