Absolute bullshit cowardice from the CMU admin. Disappointed in my alma mater, and I hope the students can maliciously comply with this nonsense in their typical creative way

Though also, even if memory access is O(1), it's still O(whatever your hash function takes), which I think in practice will be O(log n) for n distinct items since that's what the key length needs to be. (And if you ignore more bits than that of the key, you increase the collision rate.)

If you account for general relativity, I think it's even sqrt(n)--if you try to store information too densely, it'll collapse into a black hole.

I got a text from them too recently! And they were so nice, they even signed it "have a delightful day filled with success and positivity," a very idiomatic phrase often used by American government agencies!

I've been playing that (on PC) and enjoying it!

Learned today that there's a recent paper about mathematical crochet (archive.bridgesmathart.org/2023/bridges...) that cites me!

A photo of the solar eclipse. The sun's corona appears near the top, with the black circle of the moon. Below, the horizon appears as it does at dusk, behind silhouettes of trees.

The eclipse was amazing.

After managing to avoid it for years, I finally got covid :(. (Luckily, so far it seems to be a mild case of it; hopefully it'll stay that way!)

A new metal lathe, in my basement

A new milling machine, in my basement

As of a few weeks ago, I finally have the basement machine shop I'd wanted for a long time!

Finally made it over here (thank you, @hazelnym.bsky.social!). Hopefully I'll post more often than I did on that other site!
