I learned how bit-shifting and bitwise operators worked while obtaining my BSCS degree. I even used it in a programming task in my Numerical Methods class, and my programs ran much, much faster than everyone else in that class. Like, orders of magnitude faster. But I’ve never used that knowledge outside of my degree, or in any of the programs I’ve worked on since 1989. So, interesting knowledge to have, but I can’t say it was actually useful in any professional setting.
