So many people who are otherwise so committed to good things are on Substack, which is very nice to bad people, ideas, and lies. My own newsletter was launched on Ghost because the bad news about Substack isn't new.

As a Jewish Northwestern faculty member, it adds insult to the injury of this abominable agreement that DOJ claims to have done this to protect the Jews.
You've heard of the Friday night news dump. Here's the Friday night of Thanksgiving wknd dump. For special circumstances, like when the faculty assembly votes 595-4 against paying to end a shakedown and you do it anyway. Link to agreement here: bulkmail.northwestern.edu/trk/click?re...
BREAKING: Northwestern University has agreed to pay the U.S. Treasury $75 million, over the course of three years as part of an agreement with the federal government to restore funding and end investigations into the university

There is literally footage of the IDF executing these two Palestinian men in the West Bank, after they surrendered.

I really have to finish the current project. I was woken up at night again by the details of a proof, and it will keep happening until I write them down.
NB It’s a proof by analysis of possible cases/strata, not many but enough I’m afraid of missing one.

6 years ago, as I prepared to host students for Thanksgiving, I received a call informing me Harvard denied me tenure. Before I had a chance to process, it was all public. This year the memory stings more as I watch dear colleagues and friends like @durba.bsky.social experience the same violence.

This seems to be one of the top (or most visible, anyways) uses of AI that I've seen. Just making some dumb image vaguely related to the topic, and slapping it on the title slide.

All men over 50 have the right to a PSA test. It's not a screening program because you have to ask you GP. GO AND ASK! Especially if you are black or had a family member with prostate cancer.
