Dev // Cyber Toolkit – a free floating dev/cybersecurity widget
Symboles, éditeur de code et outils de sécurité, toujours à portée de main.
What it does
Un widget flottant, toujours accessible, pour les symboles, le code et les utilitaires de sécurité du quotidien. Ceci simule "ton écran" — le vrai widget serait installé en PWA et resterait épinglé au-dessus de tes autres fenêtres. L'outil reste 100% gratuit. Si tu l'utilises souvent, un petit geste aide à le faire vivre — 500, 1000 ou 3000 FCFA, comme tu veux. Envie d'apparaître sur le mur des soutiens ?

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.
