College approached and paid student to write op-ed in The Dartmouth The Dartmouth ran the article on Nov. 17 without knowledge that the College had been involved. 

The college at which I'm employed, which has signed a contract with the AI firm that stole books from 131 colleagues & me, paid a student to write an op-ed for the student paper promoting AI, guided the writing of it, and did not disclose this to the paper. www.thedartmouth.com/article/2026...

5-Year-Old in ICE Detention Is Sick, Says Top School Official The 5-year-old who was taken by federal agents in Minneapolis is being held behind bars with his father in Texas.

NEW: Liam Conejo Ramos, the 5-year-old who ICE agents in Minneapolis nabbed last week and shipped off to a Texas detention facility with his dad, is now in poor health, his school superintendent told me today www.huffpost.com/entry/liam-c...

One problem with coding agents like Claude Code is that every 10-minute administrative chore turns into a full-blown software project.

As the cost of generation goes down, the emphasis shifts towards evaluation and verification.

But scientific peer review system doesn't seem to be ready for this yet. A fundamental shift in incentive system may be due, and challenging.

It’s only logical that a city that makes it illegal to play in the streets would also not have a track record of making streets safe for kids. We can and must do better.

This can be an important reason why many people try out but don't "stick". Starter-pack is great, but it's inherently towards a very small set of the most visible users, not the niches that individual users are drawn to.

This may be a critical feature as a social platform. @jay.bsky.team

In our conservative estimate, 41 percent of Grok’s images — or 1.8 million — were sexualized depictions of women. Separately, CCDH analyzed how many were sexualized images across genders and ages. Their findings: an estimated 3 million images, including more than 23,000 of children.

Texas solar power surpassed coal in 2025 for the first year ever. Here's why. In 2025 — for the first year ever — solar arrays provided more electricity to Texas’ main power grid than coal-fired power plants.

This is a watershed moment for Texas - for the first time ever, solar supplied more electricity than coal in 2025.

I will say it again: At this rate, TX will likely decarbonize its electricity sector faster than CA.

TX clean electricity is growing at 13%,m more than twice that of CA's at 6%.

📣 Parents. If cars make your walk or cycle to school feel unsafe, that's not okay.

We need your photos of the school run! The more people can see how awful it is out there - and how unsafe it is for our children - the more power we have. DM pix or tag us in a post.

America's global pre-eminence in research was partly driven by a great power competition. At a time when China is investing more in research, and relaxing visas to attract academic talent, the Trump administration is doing the opposite.

I think two huge myths also contribute to that norm: 1. it’s a good investment (not really, over a long term historically even in places like most of California) 2. it’s financially better to buy then rent (it’s usually not)

Are 3,000 ICE agents ‘disproportionate’ to Twin Cities police forces? Their presence is bigger than the 10 largest metro police departments combined.

Latest on the federal forces in Minnesota from me and my colleague Jeff Hargarten:

There are now more federal immigration agents in MN than the 10 largest Twin Cities police departments combined.

9% of ICE is in MN right now, even though MN has less than 1% of the nation's undocumented immigrants.
