inspired by CLAUDE.md, I’ve started putting markdown files named after coworkers into work code repos so I can remind them to stop doing shit to the codebase that annoys me
for some reason they’re all mad at me now, which means ill be adding commands to JEREMY.md for an attitude adjustment

I do not spend nearly enough time thinking about pneumatic tube systems given how much joy they spark.
My New Year’s resolution will be to rectify that.

Day 16: Calling conventions matter! Pass 8 chars as separate args: stack spillage. Pack them in a struct: single register. Sometimes structs are MORE efficient than separate parameters!

the tensor product is extremely trivial to define. since it is only characterized up to isomorphism, and since any two vector spaces of the same dimension are isomorphic, the tensor product of V and W is any vector space of dimension dim(V)×dim(W)
Research proposal: give me 3m € and 10y to understand wtf tensor products are so hard to define and yet behave so neatly. Like why isn't there a simpler construction, and how come this unwieldy construction produce this... this... jewel?

A monoid M acting on a set X gives rise to a category, call it C(X), where the objects are X and the morphisms from x1 to x2 are all elements m\in M such that m*x1 = x2.
For example, C(M acting on {*}) is the category with one object, morphisms labeled by M, and composition is multiplication.

The Enigma Variations are so funny to me because Elgar wrote a pretty decent one for his wife, and then gave his publisher Nimrod, one of the most brutally heartwrenching pieces of all time. Like listen to variations 1 and 9 and tell me which one sounds like someone you’re in love with 🤷

In OCaml, is there a way to write a recursive type as the fixpoint of some explicitly specified functor (in the category-theoretic sense, idk if that aligns with what OCaml calls a functor), in such a way that it plays nicely with pattern matching?
