Sanoja — Read Words in Finnish
Learn Finnish vocabulary as you browse the web
What it does
Sanoja turns the pages you're already reading into Finnish practice. Select or double-click any word on any webpage — English shows you Finnish, Finnish shows you English, detected automatically. Hear it pronounced, and every word you look up is saved into a spaced-repetition word list so it actually sticks, with mastered words graduating into a separate "known" list. No separate app, no tab-switching — just the page you're already on. Free, open source, no account, no ads, no tracking.
Sanoja is a Finnish translator and dictionary extension: select or double-click any word on the web to translate English ↔ Finnish, hear it, and review it later with spaced repetition. Free, no account, no tracking.
Select or double-click any word on the web. Sanoja translates it between English and Finnish, reads it aloud, and saves it so you can review it later — for free, with no account and no tracking. Vocabulary that shows up while you're already reading something you care about sticks a lot better than a word list. Select an English word and see it in Finnish, or a Finnish word and see it in English — detected automatically, no language picker. Click the speaker icon to hear the Finnish pronunciation, using your browser's own text-to-speech — always the Finnish side, since that's the point. Every word you look up is saved automatically.

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.
