My colleague Sanjay Ghemawat & I have done a fair bit of performance tuning of various pieces of code. We wrote an internal Performance Hints document ~2 years ago as a way of identifying some general principles & we've recently published a version of it externally. Doc: abseil.io/fast/hints.h...

🔮Introducing OXtal – a new all-atom diffusion model for crystal structure prediction! We tackle a grand challenge in computational chemistry: predicting the structure of crystalline solids directly from their chemical composition. Paper: arxiv.org/abs/2512.06987 Blog Post: oxtal.github.io 1/8

CommonForms is cool. Guy filtered CommonCrawl down to PDFs and trained a 3-class YOLO model on it. Performs better than Acrobat. arxiv.org/pdf/2509.16506

Federal Troops Arrive in Portland and Immediately Form Bands

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. Thread 1/n

Sneakers deserves a mention as well. RIP to a legend.

Crazy shit happening in the footnotes of this ruling

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. foursquare.com/products/spa...

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.

HN tweakin out

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.

sites still doing CAPTCHAs: the clock is ticking for you

I sometimes follow Federal court cases, and it's always funny to see the weird shit that random people enter into the docket storage.courtlistener.com/recap/gov.us...

IT’S FINALLY THE YEAR OF THE LIN- ah, fuck

I recently fixed some higher-order macro nonsense in Vortex and wrote up a quick post about it, in the hopes that it might be useful to someone else notes.a10y.dev/Knowledge+Ba...

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

Breaking: A federal judge has ruled Badar Khan Suri, the Georgetown researcher held in a Texas immigration detention center since March, must be released from custody and returned to Virginia as he challenges the legal basis for his deportation.

Real question is do we got a Lou Malnati’s pope or a Giardano’s pope on our hands

Holy shit, marimo has gotten a lot better since the last time I used it 👀

Ok folks coast is clear, we're allowed to say good things about AI on this app now

So many (apparently) new followers or non-followers responding w/ a version of "they won't comply." I have a strong position on this: This is dangerous & undermines the rule of law. The *expectation* is that they will follow the ruling. Make them justify each and any failure or refusal to do so.

ICE has abandoned almost all the trapping of a lawful arrest. Its officers cover their faces, conceal their identities, use gratuitous force, and transport their targets across state lines to stop courts from intervening. The distinction between an ICE arrest and criminal abduction is disappearing.

It's wild to think about all of the things my parents' generation has lived through - Vietnam - Iran/Contra - Most of the cold war - Creation of the internet - Creation of personal computers - Creation of smart phones - 9/11 - Iraq War - Global financial crisis - COVID

Stopped at the stop sign, already safer than Maryland drivers

Last month I worked on Apache Iceberg integration for Vortex, the results of which we presented earlier this month at Iceberg Summit. I wrote a post about my experience bridging our Rust-based system to Iceberg and Spark spiraldb.com/post/vortex-...

And now, a note on Bill Owens who, until this past week, was the executive producer of 60 Minutes. We’ll be back next week with another edition of 60 Minutes.

Hello old friend

This, actually .

Definitely very normal for a US Senator to be "anxious" about "using her voice". Nothing to worry about here. All is good.

Published the ASCII illustration tool I've been working on for @oxide.computer (mitos.shared.oxide.computer) and it's even open-source: github.com/oxidecompute...

In all of this, do not forget: Congressional Republicans voted to remove their ability to rollback tariffs by saying that the rest of 2025 is one very long day

Either I’m crazy or there is only one Parquet implementation that lets you set target row group size in bytes instead of rows 🤔

I guess you can’t buy elections after all 🇺🇸❤️
