University of California faculty push back against Big Brother cybersecurity mandate School officials defend software as bulwark against ransomware, but professors fear potential surveillance of their devices

UC faculty and the @aaup.org demand the end of mandatory surveillance software use across the UC system. The future belongs to people, not to big brother!

While acknowledging that all it takes is one serious Jaylen Brown injury to derail the whole Celtics train this season, I'm planting my flag on 46 wins this year. Let's go C's.

I think every pundit is wrong about the Celtics. They may not dominate like they did the last two years, but they'll be in the mix. Counting them out seems like lazy, plug-in-the-narrative sportswriting.

Yeah, but that dimension isn't linear, it's sigmoidal. When it hits the activation point, that is a pretty well-demarcated ontological unit.

Panic attacks are also taxonic. Maybe mania but *not* hypomania??

Fun fact, Bob once asked me to put together a list of things to do with young children in NYC. When I asked him who it was for, he said "my friend, Al."

When the refutation of your argument is built into your argument. There is no execution without the idea it executes. The Manhattan project would have been a pretty futile venture without Einstein's mass-energy equivalence.

Administrators at Indiana University baselessly fired the student media director and ordered the student paper to cease its print edition, so it'd sure be a shame if this excellent digital front page were to be widely shared today

I wrote a little about some of the little details you might have missed in this video and why it hit me so hard as a trans person this morning:

UNTIL IT’S DONE, Ep. 4: Sylvia Rivera

In the 1970s, queer New Yorkers had been pushed to the margins of NYC. Our trans neighbors faced immense cruelty. But in Sylvia Rivera, they found a champion.

As we combat Trump’s politics of darkness, her legacy can light the path forward.

One of the strangest things about middle age is watching all the people who populated the world of your youth leave the world. I've come to drop Annie Hall off of my personal 'best of' list, but only because of my feelings about Woody Allen. My top 5 used to include Godfather, GF II and Annie Hall.

Yes. Which is my point. He didn't mention it and it works really, really well. I have several papers where we've shown strong out-of-sample predictions in drinking, binge eating, emotion. One of my students will be submitting a new paper soon with cannabis. So, yeah. These have all turned out well.

Welcome to #TransTuesday!

National Coming Out Day is Oct 11, so let’s get into what can be a difficult and complicated issue for so many of us: COMING OUT AS TRANS.

And for the first time since Trans Tuesdays started, I reprint my own coming out thread!

Excited that this one is live and doubly excited that I've already been able to replicate the majority of the findings in NESARC wave 1 (GAD & MDD) and wave 2 (PTSD).

If anyone knows of any publicly available data sets with *DSM-5* PTSD, please let me know!!

But as Kevin said, SPSS can output syntax. The "SPSS is bad" convo is separate from the "show your work" convo, and the latter is critical. Folks are so quick to take offense to "soft science" accusations, but this one reason why our science is soft AF. It's time to level up.

I mean, I still don't understand. Clearly I'm either too old or not "online" enough. But if it's intentional antagonization, that's some fucking bullshit. Of all the crap we have to deal with in this stupid epoch of ours, the explosion of intentional antagonization of vulnerable people is the worst.

Great googly moogly!! I just submitted a review where I recommended reject. Went and checked what the other reviewers thought and R1 recommended 'accept with minor revisions'. I am just so confused right now.
