spent 4-10 hours a day memorizing lists of prime numbers
Every day
I've memorized values of cos in 5° increments because I thought I was gonna be able to do long-range shooting in a blue state but not primes.
Have you ever used wget or curl? I used one or both with the verbose option enabled. I was downloading doomed files from a website with curl and/or wget and used the verbose option instead of the silent mode option (which I think is a thing). I'm pretty sure all the time displaying text to stdout is basically a big waste of time, but I hope stderr still shows up with silent mode on. In Windows 7 or 10 I think I may have been able to download many more files than I did if only I used silent mode and not verbose mode. I know for sure dir|clip grabs text way faster than dir when you are in a directory with many files or folders. If your goal is to copy the output of dir, dir|clip is like silent mode.

Neat. I wonder if military dudes memorize those values.
