Tallinn, who led Anthropic's series A, funds METR, the "auditing institute" people took seriously 🙄 After criticism that METR was laughably NOT independent, Anthropic announces they'll pay Accenture to "audit" Accenture had acquired Tallinn firm which will be doing the "auditing" Full circle 🙄

quite a speech! www.youtube.com/watch?v=3y9J...

just read a post on linkedin; AI generated and about their son's medical issue, relating it back to business. i'm happy the kid's alright but have complicated feelings about using the kid's medical journey as content particularly when they couldn't be bothered to write it their self?

move fast and break things is just a nicer way to say fuck around and find out

I've been reading High Output Management by Andy Grove and while it's a classic for a reason it feels very relevant today while also providing a lot of historical context, even for its time, which I appreciate.

This piece I wrote on CO₂ removal (CDR) is probably the most widely read work on the topic, but it's definitely the most impactful thing I will ever write. Please read it to see how I think about CDR (and how I think you should think about it too). rdcu.be/dbFbB

Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).

🔇 🔇 🔇 My book, Deep Unlearning, is now available for preorders! I don't know how people write so many books because this one took a lot out of me. It turns out, I had a lot to say 😂, with editors cutting out 50k of my words 🫣 ✴️ You can now preorder it at www.simonandschuster.com/books/Deep-U....

"I read the new UN climate report so you don’t have to." Highly recommend this summary of last week's UN climate report by @ayanaeliza.bsky.social: ayanaelizabeth.substack.com/p/i-read-the...

A benefit to writing like ai is that my writing won’t get included in the training sets since it would be flagged by their content filters

i talked some shit about AI on LinkedIn (low effort AI posts) and it's gotten me the most engagement compared to my technical writing and i'm not sure how i feel about it. i'm not going to stop my technical writing, but content that appeals broadly might expand reach of everything else. til.

Here's part two of the lockless bounded MPMC ring buffer article. It clarifies the much longer first post then gets into branchless index computation and measuring tail latency with DTrace and USDT probes: k-cross.github.io/limits2

Quintessential Trump: In 2025, Trump axed the program to combat New World Screwworm, stating that they had "saved" $1.5 million a year. In 2026, the Trump announces a $1 billion emergency program to combat the Screwworm outbreak. $1 billion would have funded the old program for 667 years.

When I think of polymarket or kalshi I can’t help but think of everyone behind them are from the movie Rat Race

Signal users should pay attention to this.

Absolutely badger your senators. Become the badger. Become a family of badgers in their phones.

I did some napkin math, and we're talking about a high speed rail network five times the length of the Shinkansen system, from 2020-2025's investment alone. Can't help wondering how many of these routes we could have built. youtu.be/wE5G1kTndI4?...

spacex buying cursor is the funniest fucking thing i've read in a while

also these transcripts show that you should not be listening to ChatGPT for legal advice lmfao

He’s got a better plan to get out of dinner than Iran…

This is so funny. What if he’s worried this guy can actually read his mind and tell everyone what a big pedophile he is

Classic overreach!

NEW—I got an exclusive excerpt from a USAID whistleblower's new book that made me gasp multiple times. It details Trump's dismantling of the humanitarian aid agency & his team/DOGE's shocking ignorance to public health. 'Into the Wood Chipper' by Nicholas Enrich is out tomorrow. Read excerpt here:

Feel like I'm speed running learning how local election politics work right now, had no idea about the different "strong mayor" and "city council" systems.

We need to talk a bit about how utterly absurd the March heatwave was in the USA. This heatwave would have been impossible without a boost from climate change, but even with climate change it remains a deeply unlikely event. A thread looking at some of the numbers. 🧵

The Trump presidential library should be named "Trump Center for Kids who can't Read Good"

Kalshi and Polymarket remind me of the movie Rat Race

Lt. Sharpe and Sgt. Harper for the win.

This is Nathan Cavanaugh, another DOGE staffer explaining how he flagged grants at NEH for "DEI" which would be reviewed for termination. 404 Media has reviewed hours of this footage and we'll have more soon. Part of a lawsuit by @acls1919.bsky.social, @modernlanguage.bsky.social + @historians.org

I decided to write about the internals of AI agents and feel like I covered memory pretty well. I'd love any feedback on it if you have it. k-cross.github.io/ai_agents (no trackers are on the site)

$1400 to go to keep this Minneapolis immigrant family in need safe, housed, and out of eviction court! Can you help make this happen for them tonight? V: @Ian-Coldwater CA: $iancoldwater PP: @coldwater Please share and give if you can! I really appreciate you and I know they do too 🫶🏻

Low key irritated that a crab can mean claw or rust now. They could have picked a different shellfish… maybe it’s okay because there’s like five independent evolutionary paths to crabs

This incredible story underscores, amongst other things, the need for trust and transparency in arching tools, and for web archiving toolchain to be fully open source and archives to be verifiable.

I'm pretty sure Trump meant to call it "Bored of Peace."

On February 19, 1942, President Franklin D. Roosevelt signed E.O. 9066, authorizing the forced relocation & incarceration of more than 125,000 Japanese Americans, solely because of their heritage.

Another resistance quilt finished this week. The eye is my own design, the letters are a fpp pattern by QuiltByNight, the rounded corners and black binding are meant to resemble the phones we the people are using to document the horrors and disprove the government’s lies about what they are doing.
