I got a used monitor from the thriftshop yesterday, and today I bought myself a flashdrive that's a combo USB A & C. That was an impulse purchase. Not sure exactly what I'll do with it, but it could come in handy. I saw it while I was buying a drive for someone else.
I also got a 1.2k page pdf manual for gnu octave. Not sure how motivated I am for that. Time to be winding down my math/work stuff, and I don't know if I feel like learning new (work)stuff.
