Killed. NSF’s SBE was killed, in violation of law. The President does not have the power to choose to kill programs at a whim by defunding them. The imperial presidency was a mistake and we are in a separation of powers constitutional crisis.

Fun story. As I was a grad student I published a 1st-author paper on co-rumination in J of Adolescence that got discussed in the NYT (side note, the reporter interviewed me but only named my advisor in the story). Our PR office wanted to build on it for more press, so they wrote up a press release…

Wow. Proponents of the ICE taser gloves are openly saying that one reason they love the gloves is that they doesn’t leave any marks or proof that they were used, making it harder for people to sue when they’re shocked excessively.
Mother Jones

"In today's society, you know, everybody's filming everything, everybody has a cell phone," Glueck said. If an officer punches someone on camera, that can go viral in an instant; even a standard taser leaves puncture wounds. But "the glove is low optic, and it looks better on camera, and it looks better to those witnesses. With a glove, there are no burn marks or scars."But local police across the country are still eagerly buying the gloves—in large part so that they can harm people and avoid being sued for it. It's been successful "from the patrolmen to the jailers," Lumpkin County Sheriff Stacy Jarrard said in a Compliant Technologies promotional video. "It's been a great tool as far as mitigating liability," according to Nelson County Jailer Justin Hall.
Bob Couey of the Floyd County Sheriff's Department sung the GLOVE's praises, too: "I highly recommend these gloves to anybody that's looking for a utility they can use that is conducive to not leading to lawsuits."

kids today are literally confused about whether "partying" was real or an urban legend
From Reddit: 

> Did millennials really party all the time?

> Gen Z here. I was shocked when I found out from a millennial co-worker that y’all had teen clubs. I heard about house parties, but dedicated teen clubs? Then when it was time for college, you went to the club or had some kind of party every single weekend, living it up. Now some millennials on TikTok claim that after college, they were partying on work nights, still clocking in the next day. For some reason, the teen clubs have since disappeared. I’m 23 now but even when I was in high school, that was not a thing. House parties were not that common either. They were more like get togethers with a small group of friends. We went to malls, but they were dying out at that point. Is it true that you were really living life this good? Or is it just exaggerated? I feel like my generation doesn’t really have fun like that and everyone is just super depressed and alone, more so since Covid. Even I’m pretty introverted, which sort of sounds ridiculous given this post. 😂 Just so you know, when I think of a “millennial party” I think of something out of Party Rock Anthem, Project X or Roderick’s party from the second DOAWD movie. It’s like I get nostalgia from something I didn’t even live through. I just feel like I didn’t really LIVE, if that even makes sense

This essay from @bschmidt.bsky.social on how history rejected computational methods, & so "quantitative history" ended up in the social sciences, & "digital humanities" in literature, with no historians doing computational work, is fascinating, & worth a read: dhdebates.gc.cuny.edu/read/computa...
The first is a working paper by three economists—Elliott Ash, Daniel Chen, and Suresh Naidu—from 2017. While the authors are economists, the actual contribution—summed up in a title that few historians would think debatable, “Ideas Have Consequences”—is about legal or intellectual history. It presents a powerful and discrete account of the transmission of ideas across social networks through textual analysis. The substance argues that privately funded Manne seminars in law and economics—which were attended by a substantial proportion of the federal judiciary—affected the language, decisions, and sentencing of federal justices who attended them and thus, by implication, allowed large-value conservative donors to capture the federal judiciary. The effect seems robust to a variety of covariates [...]

Reading this paper was exciting, but looking through the tools and tricks and sources also made me feel like someone in a science fiction movie encountering an artifact sent back from a few decades in the future. The extraordinary quality of data that economists can obtain is almost unimaginable to humanists. It is not just a million or so circuit court votes and 300,000 opinions but also the institutional capacity to file Freedom of Information Act (FOIA) requests to get the exact years of attendance for every judge who went to the Manne program and the disciplinary capacity to casually use relatively new methods like word embeddings without spending pages slowly, gently analogizing them to some “simpler” concept. Humanists wandering through algorithms seem to have to justify using an algorithm by first identifying which Borges short story—whether about the Map of the Empire, the analytical language of John Wilkins, or Pierre Menard and the Quijote—it most closely resembles.

Surveillance expansion is not inevitable. We the people can question it, demand oversight, and protect our privacy from law enforcement. If this concerns you, pay attention to what your city is doing and push for real limits before Flock's surveillance camera network spreads further.
Verona ended its Flock contract outright protecting over 14,000 local residents from having their data harvested by a private company and potentially ICE. Local officials responded to community concerns around privacy and data sharing.After public pressure, Dane County voted to remove Flock funding from the sheriff's 2026 budget. Sturgeon Bay in Door County also ended its agreement with Flock.Oshkosh unanimously voted to end its newly renewed contract between Flock and Oshkosh PD after Flock officials made false statements regarding camera capabilities at an Oshkosh Common Council meeting.
