I don't use Microslop for any of my personal stuff, but work has us using Teams and Office 365 Copilot (new) or whatever weird-ass name they've given it now.

Just returning here to say that old fashioneds are my favorite cocktails and yet so many places don't make them.

(Also very hot piece)

My experience working with executives is that they are often the dumbest people you will ever meet.

Fuck Microslop. I hate having to use their products for work.

Thanks! It's a difficult diet and a hard workout routine but it's working, I'm gaining!

Being a vibe coder is honestly embarrassing as shit. Even moreso being proud of vibe coding.

Won't have padding (except legs because digitigrade) so the belly and muscles will be REAL.

Very very good day.

Had a nice teaching session, am wrapping up a big proof, and I lifted lots at the gym.

...and I got a fursuit slot from the maker I really wanted πŸ§‘πŸ‘€

A manifold with a boundary is not a manifold.
Learned that ages ago and it made me very interested and curious about topology.

Unfortunately it's a hard subject to teach.

I don't think mnemonics are necessary at a higher level. Math becomes intuitive, but there might be a few.

"Left is Leaving, Right is Returning" is what I tell students for remembering the directions of adjoint functors in category theory.

I just realized I like reasoning about structures. When you learn that mathematics is nothing like what you do in school, it becomes more interesting. It's not just remembering equations or plugging in numbers, but it's exploring concepts.
