Tachyon
Full-text search in an 8.7MB Rust binary
What it does
Tachyon is an open-source, self-hosted full-text search engine in Rust - BM25 relevance, typo tolerance, facets, filters, autocomplete. No JVM, no cluster. Ships as a single 8.7MB binary. docker run -p 8108:8108 adikeshri/tachyon:latest and it's up.
Tachyon is an open-source search engine designed for fast full-text search without the operational complexity of heavyweight search infrastructure.
Fast, self-hosted full-text search without the operational complexity of heavyweight search infrastructure. Search infrastructure doesn't need to be complicated. Tachyon provides the core capabilities developers need to build fast application search while remaining lightweight, self-hostable, and easy to operate. Run Tachyon, create a collection, index documents, search. That's the whole workflow. docker run -p 8108:8108 adikeshri/tachyon 2. Create a collection bash curl -X POST localhost:8108/collections \ -H 'Content-Type: application/json' \ -d '{ "name": "products", "fields": [ {"name": "title", "type": "text"}, {"name": "description", "type": "text"}, {"name": "brand", "type":…from tachyon.adityakeshri.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.
