I wanted UpNote's clean editor with Obsidian's local files, minus the bloat and the lock-in. It didn't exist, so I built it: plain Markdown, stored on your own disk. Slash commands, tables, code blocks with highlighting, and live KaTeX math. A clean WYSIWYG that writes plain Markdown you can read with cat , and a source mode for when you want the raw text. HelixNotes pulls every - [ ] checklist from across your notes into a single Tasks view. Set priority and due dates per row, then work in a list or drag tasks around a calendar. Link notes with [[wiki links]] and the graph fills in on its own. Hover a node to trace its connections and find the ideas that tie everything together. Daily…from helixnotes.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.
