ShotSweep
Visual regression testing from the command line
What it does
Capture screenshots of any site — single URL, sitemap, or CSV — and diff them between runs. Catches visual regressions your test suite can't see, before your users do. Full-page or sectioned, light/dark mode, authenticated pages, CI-ready exit codes. Open source, MIT licensed.
Screenshot any site — single URL, array, CSV, or a whole sitemap — full page or sectioned, with real auth support and visual diffing between runs.
Capture real pages with a real browser, compare them before and after a change, and let CI catch visual regressions before they reach production. This runs the same capture engine used by the CLI against sites we control. Same browser, same waiting logic, same screenshot pipeline — just without installing anything. Real capture, run live against form-validation.nforshifu234dev.com — same viewport and load-wait logic ShotSweep uses. Limited to a handful of sites we control, rate-limited, cached for 30 minutes. Your build can pass. Your unit tests can pass. Your API tests can pass. Your application can return HTTP 200. A CSS change can still break the interface.

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.
