They pulled the plug on this disaster, but I hope they're still sued into bankruptcy as a warning to other companies.

New study highlights the day-to-day importance of autistic flow | BPS Work by Daniella Wain and colleagues details a non-pathologising view of flow states in autistic individuals, and how they maintain wellbeing

Autistic "flow" or deep immersion can be essential for autistic people's wellbeing. It is not necessarily a sign of 'withdrawal' or escape, but a "rewarding, adaptive way of regulating, coping, and connecting—with others, themselves, and the world."

The case of temporary visitors was more complicated at common law. The
parents, if lawfully present, were under the temporary protection of the sovereign.
That is why one judge in a famous case, Lynch v. Clarke, held in 1844 that a child
born of temporary sojourners was a citizen. But the rule was contested because of
increasing international travel and the resulting dual allegiances. Joseph Story
suggested that an exception for temporary visitors would be a “reasonable
qualification” to the rule. Henry St. George Tucker in his treatise stated flatly that
temporary visitors fell outside the common-law

I'm afraid I can't just sit here and say nothing when another law professor gives false testimony to Congress about the meaning of the Fourteenth Amendment.

Ilan Wurman has given false testimony to Congress, being fully on notice of the falsity. I do not think this is fairly debatable. 1.

Just to show how stupid this was, a project on Harriet Beecher Stowe's religious writing got flagged as DEI.

Grammarly went further and resurrected a historian who died in January 2026 to serve as an ‘AI’ reviewer/editor. It’s grotesque, the company is enslaving digital ghosts all so they can get a few clicks more.

One might add that Spanish was a language on about a third of what is now US territory before English was.
But I won't pretend to be surprised that the Idiot-in-Chief doesn't know what the Treaty of Guadalupe Hidalgo was.

Turns out that trying to explain what he means by DEI without admitting to his racism, misogyny, and homophobia is, um, hard for him.

A win for academic freedom.

Being a professor is a tough job because we have a lot of competing pressures, but remember that we have an obligation to govern ourselves.

Perhaps Thoreau's most powerful line from CIVIL DISOBEDIENCE: "Under a government which imprisons any unjustly, the true place for a just man is also a prison."

Arguably the US-Mexico War was even more unpopular, (although of course there was no polling at the time to give us concrete numbers as to public support). But consider that the US-Mexico War was greeted by anti-war petitions to Congress and Thoreau's classic text, CIVIL DISOBEDIENCE.

Nuclear experts undercut White House claims about Iran reactor at heart of case for war The Trump administration sent negotiators without nuclear expertise to lead talks on Iran’s enrichment program. Now, its public case for war centers on a facility that experts say cannot do what offic...

This is a technical story with stunning strategic implications. It is quite possible the US launched a massive war because Jared Kushner and Steve Witkoff lacked the technical expertise to even understand what the Iranians were offering in negotiations. Absolute idiocy.

Honestly, I am absolutely disgusted by academics suggesting that AI can do the reading and writing for you. At a certain point, what you're bragging about is fraud. And in a broader sense, what you're contributing to is the erosion of knowledge and the destruction of trust in academic publishing.

Justin Fox Deposition (Part 3) in MLA-ACLS-AHA Lawsuit about the NEH YouTube video by ModernLanguageAssoc

It's stunning how ignorant the DOGE bros were who were sent into agencies. Justin Fox cannot even articulate in his own words what his "present understanding of DEI" is: he can't even formulate a coherent sentence about it. I wouldn't hire him for basic tech support. #NEH

To clarify this: the context is college sports. Trump is saying that Russia helping Iran target Americans in a war is less important than the pay structure for athletes. (1/3)
