💡 Academic Tip: always get a haircut the first week of classes.
That way, (1) the students won't think your head is a bird's nest forgotten in the lecture hall, and (2) you can track what's left of the semester by how much you look like a Beatle.

My email got hacked. The damage is limited to the intruder accepting an excessive amount of reviewing obligations on my behalf. Regrettably I will not be able to complete these.

Hot take for POPL: the PL community is still mostly in denial about AI. This is bad because PL+AI go great together
- PL can solve the hardest problem with AI - trusting the output it produces
- AI can solve the hardest problem with PL - finding enough engineers who can even use the tools
