There might be a mine here

Ironic that this itself is an obvious slop site

Thank you :)

I love these! “Not Quite the Same” sounds a lot like “The Wrong Abstraction” from my list. It’s a really important point and I’m glad to see there are more articles about it!

Thanks for the callout! I have much more experience with geography but you’re totally right. I’ll add a note
Re:What Is a Nomogram and Why Would It Interest Me? on Friday June 26, 2026 @05:43PM (#48692367)
The US Navy still uses nomograms for chemistry control on nuclear reactors!
This is so cool. I would have loved this in college.

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

How does this differ from something like MarineTraffic?

Nice, that’s really cool.
Re:Tuning Semantic Search on Jfmm.net on Sunday February 01, 2026 @02:03PM (#46848428)
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?
Re:Tuning Semantic Search on Jfmm.net on Sunday February 01, 2026 @11:16AM (#46847181)
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?
Re:Tuning Semantic Search on Jfmm.net on Sunday February 01, 2026 @11:07AM (#46847116)
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 :)

Re:Tuning Semantic Search on Jfmm.net on Sunday February 01, 2026 @11:01AM (#46847060)
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?
Re:AI at work is anti-labor by design on Wednesday January 28, 2026 @10:12AM (#46796371)
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.
