Garrett Graff quotes Nicholas Grossman: “Evidence keeps accumulating that LLMs are a powerfully useful technology for people who already know what they're talking about, and a dangerous outsourcing of cognitive function for people who don't.

Exactly. I’ve heard both parts from my colleagues.

Wondering why data centers are as unpopular as nuclear waste? It's not the data centers.

The problem is both more obvious and more fundamental: The daily lived experience of the AI boom sucks. www.doomsdayscenario.co/p/ai-is-maki...
AI is making everything worse
The political problem isn't the data centers — it's that AI is a turd mountain looming over daily life.

When comparing developer-written code with “AI”-written code, remember to consider the value of other process outcomes, not just the code itself.

New blog post: History of Image Display in MATLAB, Part 5: 1997-1998, MATLAB 5, and Image Processing Toolbox 2

"MATLAB 5 saved image processing in MATLAB."

At long last, I have continued my series about the evolution of image display in MATLAB.

PHOTO RELEASE NO.: STScI-PRC95-01 HUBBLE PROBES THE COMPLEX HISTORY OF A DYING STAR This NASA Hubble Space Telescope image shows one of the most complex planetary nebulae ever seen, NGC 6543, nicknamed the "Cat's Eye Nebula." Hubble reveals surprisingly intricate structures including concentric gas shells, jets of high-speed gas and unusual shock-induced knots of gas. Estimated to be 1,000 years old, the nebula is a visual "fossil record" of the dynamics and late evolution of a dying star. Credit: J.P. Harrington and K.J.

I just saw the New York Times obituary for Cleve Moler. I noticed that the reporter who wrote it posted a wonderful note in the comments section just below the article.
Here is a gift (paywall-free) link to the article:

www.nytimes.com/2026/06/11/s...
A comment posted by obituary reporter, Clay Risen: "One thing you won’t often see us do in obituaries is talk about whether someone was kind (or a jerk). It’s subjective, and usually irrelevant to their significance. But over and over I heard how kind Cleve Moler was. I’m so glad to see that reflected in the comments."

A reminder to the news media: “conflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

You have to read this. Firsthand affidavit from one of the women who was there and recording the video. She talks about how Alex Pretti was directing traffic when she arrived. She watched him be killed in front of her. She's afraid to go home, worried she'll be arrested.
1. I am a resident of the Whittier neighborhood of Minneapolis, Minnesota. I am over 18 years of age. I am a children's entertainer who specializes in face painting. 2. On Saturday, January 24, 2026, at about 8:50 am, I was getting ready to go to work when I heard whistles outside. I knew the whistles meant that ICE agents were in the area, so I decided to check it out on my way to work. I've been involved in observing in my community because it is so important to document what ICE is doing to my neighbors. Connecting to your local community and knowing who your neighbors are is something I profoundly value. 3. I drove to Nicollet Ave. and 26th where I could hear the whistles coming from. I turned south onto Nicollet. There were already several ICE agents there and they'd set up a sort of vehicle convoy on Nicollet and 28th. There were also about 15 observers there, recording and observing ICE. 4. I saw ICE agents surrounding cars and punching car windows. I also saw them stopping vehicles further down Nicollet, so I backed up because I didn't feel safe continuing on. 5. I noticed a man sort of acting to help traffic move more smoothly. He helped me find a place to park. I got out with my whistle and my camera. I went over to him and said something like, "I'm going to film and use my whistle." 6. It seemed like most ICE activity was happening a little farther down the street from us, near 27th. Someone was being thrown to the ground. 7. I started recording. There was an agent by a car across the street. Two observers were a few feet away from the agent, blowing their whistles. One was wearing a backpack. 8. I and the man who was observing and helping direct traffic were standing in the street. There was a phone in the man's hand recording a video. 9. An agent approached and asked us to back up, so I moved slowly back onto the sidewalk. 10. The man stayed in the street, filming as the other observers I mentioned earlier were being forced backward by another ICE agent threatening them with pepper spray. The man went closer to support them as they got threatened, just with his camera out. I didn't see him reach for or hold a gun. 11. Then the ICE agent shoved one of the other observers to the ground. Then he started pepper spraying all three of them directly in the face and all over. The man with the phone put his hands above his head and the agent sprayed him again and pushed him. 12. Then the man tried to help up the woman the ICE agent had shoved to the ground. The ICE agents just kept spraying. More agents came over and grabbed the man who was still trying to help the woman get up. All three of the observers looked to have been badly affected by the pepper spray. I could feel the pepper spray in my eyes. 13. The agents pulled the man on the ground. I didn't see him touch any of them-he wasn't even turned toward them. It didn't look like he was trying to resist, just trying to help the woman up. I didn't see him with a gun. They threw him to the ground. Four or five agents had him on the ground and they just started shooting him. They shot him so many times. 14.1 don't know why they shot him. He was only helping. I was five feet from him and they just shot him. 15. The video I recorded of what happened accurately depicts the events leading up to the agents shooting him and several minutes afterwards. The video is attached as Exhibit 1. 16. I have read the statement from DHS about what happened and it is wrong. The man did not approach the agents with a gun. He approached them with a camera. He was just trying to help a woman get up and they took him to the ground. 17. I feel afraid. Only hours have passed since they shot a man right in front me and I don't feel like I can go home because I heard agents were looking for me. I don't know what the agents will do when they find me. I do know that they're not telling the truth about what happened. I've heard that other witnesses might have been arrested and taken to the Whipple Building. 18. I am disgusted and gutted at how they are treating my neighbors and my state. I keep alternating between crying and feeling determined it is important to remember the value of documenting injustice. We show up for the people who need us to bear witness, because it can't just be one group of people bearing the brunt of their tyranny. This is a struggle to protect our freedom and democracy, those things are on the line. He lost his life for those values. I declare under penalty of perjury that everything I have stated in this document is true and correct. Dated and signed on Jan 24, 2026 in Hennepin County, State of Minnesota.

Pam Bondi just sent a letter to Minnesota officials saying ICE will leave if the state turns over its voter database to Trump.

Guess what? This has never been about safety or immigration. It’s a pretext for Trump to take over elections in swing states.
