Technology being everywhere doesn’t mean it belongs everywhere. The tech industry wants us to believe that AI in early education is not only inevitable, but necessary. We don't see it that way. This week, we announced a moratorium on generative AI for public school students in 2-K to 8th grade.
We’re eliminating AI use for students in 2-K through 8th grade for the upcoming school year.

If it looks like an Amazon delivery and drives like an Amazon delivery, then it's an Amazon delivery, right? Not according to Amazon. Big companies like Amazon have built a vast network of subcontractors who deliver their packages while shielding them from accountability.

At SIGGRAPH 2026 I saw this absolute banger of a paper by James and James. Beautiful imagery, matched by beautiful technical work, by a father and son team, which won a best paper award. I've always loved marbleization patterns. dougjam.github.io/mixwell-2026/ www.linkedin.com/feed/update/...

Inspired by @mmalex.bsky.social's dots experiments recently, tried to do some kind of "particle DOF" in the fluff renderer, effectively blowing out every particle's microparticles which gives a kind of uncanny effect that also melts my GPU with overdraw.

interesting rationale from a prospective juror in the Elon Musk Twitter stock manipulation case
Judge Breyer: Okay. Thank you very much. Juror 96, I think that you also have strong views. Could you set them aside?

Juror 96: I believe that in a criminal trial, I would feel morally obligated to convict. However, in a civil trial, I feel I can set those views aside.

Judge Breyer: That’s interesting.

Juror 96: I’m happy to expand.

Judge Breyer: Sure.

Juror 96: I believe it would be to the benefit of the human race were Mr. Musk to be sent to prison. However, I don’t believe a loss of several hundreds of millions of dollars in a civil trial would be even a drop in the bucket to his wealth, so it doesn’t really matter. Therefore, I would be able to consider the facts.

If you want to do something like this, why not buy a $150k home in a small town in Italy, France, Spain, or Mexico, instead of having nine people share one bathroom after they eat at a restaurant called "Stinky's?"
Someone on twitter writes: "You could move to Aplington, Iowa and get a job at the post office making $25 an hour to start, meet a nice girl at the First Reformed Church and take her on a date to Stinky's Bar and Grill, and get married and raise up seven children in this house but you will not do it." There's a screenshot of a Zillow listing showing a rundown 8 bedroom, 1 bathroom home for $95,000.
