Zilog Z80, 1976 – 2024.

https://www.mouser.com/PCN/Littelfuse_PCN_Z84C00.pdf

Over its 48 year life, the Z80 found its way into inumerable devices.

It's perhaps most famous for being the CPU used in the ZX Spectrum, but could also be found as a sound co-processor in the Sega Mega Drive and SNK's Neo Geo arcade boards, among others.

I remember finding one inside my first HP inkjet printer back in the late 90's, and my parent's Sony Trinitron CRT, handling the on-screen menus (and teletext).

R.I.P. 💀

Bogosort is a joke search algorithm; it "works" by randomly shuffling the input, checking if it's sorted, and if not shuffling it again.

Via the Sigbovik 2024 proceedings, we are introduced to "bogoceptionsort".

It randomly shufflles the text of the bogosort program and then trying to run that against the input, and if that doesn't work, shuffling that source again.

And I realized, this terrible, hilarious joke sorting algorithm is pretty much how re-orgs work.

Never had a cat scratch heads down before. Won't be the same when he leaves.
