I recently had to do linear algebra for the first time ever irl. I’ve been out of school for ~15 years. I was trying to make a rotation matrix to transform some points in 2D space. It took me a very long time to remember how it’s performed yet alone “transformation matrix” which is something I’d never heard of before. I got my code all working and was so proud, then later found that one of the r packages I was using could have just solved it all automatically :/

Bad lieutenant and wild at heart are really good out there movies

Red currants :)

Edit - apparently they are black currants. Still tasty!

This was nearly a decade ago. I worked at a small app company (5-10 developers) for a bit that used Ruby on Rails for our product. The product was in active development, but was available to customers so it was “done”. We were hiring a senior level dev to oversee the team and we interviewed this guy (maybe in his 40s?, a but older than most people in tech) and he said his first order of business if hired would be to refactor the entire code base to php. I don’t think he was joking. I’m not sure why he interviewed.

I’ve never seen anything as extreme as you describe, but when I took the GRE I met a guy kind of like this. After you finish the exam it gives you an estimate of your score, but your real scores are sent to you weeks later. On the way out some guy asked me how I did (fairly well but not 97% plus on anything). He was like “oh damn if you don’t get above 95% on math then you can’t go to grad school in STEM lol”. I asked him what he got in the reading and writing and he said <33% “but that isn’t important for grad school” lmao
