I’m implementing the Lox programming language (from Crafting Interpreters [0]) in Rust.

How does this differ from something like MarineTraffic?

I use full length vectors (512 dimensions) and have seen very fast lookups with pgvector (HNSW index) and sqlite-vec on 20k vectors. I think any decent vector database should be able to handle 44k entries… which one are you using now?

This is really cool. How is reranking built in? Is there a model that runs inside the database? If so, how did you choose it?

Thanks! Yeah embedding is simple enough and my needs were small enough that I didn’t want to pay. Both llama-server and ollama are great options, and if container size isn’t an issue you get a greater variety running what you want with sentence transformers.

Cool site :)

This is a really cool idea. By “different models” do you mean models fine tuned on different sources? How would you decide how to classify chunks?

Aren’t most inventions anti-labor by this rationale? We employ fewer farmers than we used to, but this is good for society because people who would be farmers are now working on other things.

> 5 - 9 means strong effects, definitely not placebo.

It’s impossible for anyone to say this convincingly about their own experience. If it were easy to tell whether an effect was due to placebo, we wouldn’t need blinded trials!
