- TMTubePen – My attempt to get more out of YouTube learning2025 · tubepen.com · ▲74
Hi HN! I made this because I always forget what I'm trying to learn from YouTube. Test yourself: Can you remember the main concepts from the last (educational) video you watched? So, why not highlight and take notes on YouTube videos, just like in books? That's TubePen. Sign in, replace "youtube" with "tubepen" in your YouTube URL, and you're ready to retain more from your videos. I’d love your feedback! What do you think of my landing page? Use the 10-day free trial and see if it’s useful for you. Thanks!

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.

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.
