CommonForms is cool. Guy filtered CommonCrawl down to PDFs and trained a 3-class YOLO model on it. Performs better than Acrobat.

Delighted to see our paper studying the evolution of plasmids over the last 100 years, now out! Years of work by Adrian Cazares, also Nick Thomson @sangerinstitute.bsky.social - this version much improved over the preprint. Final version should be open access, apols.

Sneakers deserves a mention as well. RIP to a legend.
Lastly, consider watching some of his films this week. My favorites include Butch Cassidy and the Sundance Kid, All the President’s Men, Three Days of the Condor, The Sting, Jeremiah Johnson, and All Is Lost.

Rest in peace to a man who has given us much.

We just launched Foursquare Spatial Desktop – a geospatial analysis tool powered by embedded DuckDB and built on sqlrooms.org. Everything runs locally: your data stays on your machine, no cloud needed. A modern reimagining of Kepler.gl. Mac only for now. More coming.

I feel like I need to level up my agentic coding. 90% of my usage is asking Claude Code to generate a first draft of something. Then I'll follow up and guide it to do some targeted improvements, but eventually I take back manual control. I haven't used context truncation, tool calls, hooks, etc.

@rust-lang.org-people, what's an open source project that you think has good error handling? I've been using thiserror for the past ~3 years in multiple codebases and I keep running into the same corners I'm unhappy with, and I want to read some new patterns/designs and get some better ideas

SUPER EXCITED about this. However, I highly recommend that if you haven't read the book, please go into this movie blind. Or at the least. Turn off the trailer after the 2min mark. Idk why every movie trailer has to spoil the plot nowadays.

When anti-AI zealots say untrue things like “ChatGPT can’t search the web,” they’re just hallucinating because their training data ends in 2022. The next generation of anti-AI zealots will be better. Eventually, we will achieve “general anti-AI,” which will only say true things about LLMs.

I sometimes follow Federal court cases, and it's always funny to see the weird shit that random people enter into the docket

In this thread, a bunch of people with nearly zero ability to think missing the point entirely.

This is easily good enough to fool *most* people, we really need to be aware what the capabilities are, or be easily fooled by them

SCOOP: In Feb, federal agencies "lost" many #FOIA requests but you probably had no idea. It turns out that the FOIAs disappeared due to an "insider threat attack" by 2 employees at a software company who were previously convicted of hacking into the State Dept
