Download video and audio without the clutter
What it does
Aevum is a free and open-source desktop app for downloading video and audio from sites supported by yt-dlp. It provides a simple GUI around yt-dlp and FFmpeg, with no ads, accounts, subscriptions, or unnecessary clutter.
Download videos and audio from any site. Yeah just that. I don't like ads. - Alonera/Aevum
Aevum — a simple, self-contained desktop app to download videos and audio from any site : YouTube, Vimeo, Twitter/X, Dailymotion, Twitch, and ~1,800 more (anything yt-dlp supports). No installation, no dependencies: everything is bundled into a single executable ( .exe on Windows, AppImage on Linux). Free, open source, and completely ad-free — no ads, no tracking, no bundled extras. Just the download. Aevum runs on your machine. It contacts GitHub, and only for updates. Downloading is entirely local — Aevum talks to the video sites you paste and nowhere else, and your files and history never leave your computer. The single exception: when you open Settings , it asks GitHub what the newest…from github.com

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.
