A mathematical statement involving operator inequalities and tensor products. Statement in LaTeX: Let $X,Y$ be operators on a finite-dimensional Hilbert space. If $0\leq X \leq Y$, then $X^{\otimes n} \leq Y^{\otimes n}$ for all $n\in\mathbb{N}$.
A little task to get your brain going today: Prove the statement in the picture!
Absolutely fantastic hire!

I know I've said this a trillion times but I have to say it periodically to keep from going insane:
The right ran a huge, well-funded, & ultimately successful campaign to completely take over political media & the infosphere more generally. This is by far the most important political development...
writing your own code will soon be considered charmingly eccentric, like churning your own butter.

In my utopian vision of the future, instead of offloading all the pointless, annoying work tasks (like reports that none one will read and needlessly opaque forms) to robots, we restructure work and society so that the pointless tasks don't happen at all.
I’m “there’s too many teenagers over there to stop for lunch” old
what the fuck
this really seems like another case of them going after someone prominent to send a “nobody is safe” message and what’s actually going to happen is continuing to polarize everyone but the worst of the worst against them
because how the fuck is this kid a threat to anything

This is the kind of thing a rich CEO says at the beginning of a science fiction movie to establish for the audience that he is a sociopath and the villain.

Something about LLM hype culture renders a man immune to the experience of embarrassment. If I couldn’t tell the difference between PhD-level scholarship and grammatical gibberish I simply would not announce that to a global audience.
Is there anything better than to have to be somewhere for a meeting and then the meeting is cancelled and it turns out you don't have to go? I think not.
Every now and then I see a post and think ‘oh no, you don’t do your thinking with those concepts do you? Those are posting concepts, not thinking concepts’ and I think this tracks a meaningful distinction.
There is a case to be made that any board of a university that signed an agreement that required paying a fee has breached their fiduciary duty and I think somebody should explore it
