Today I learnt that the original name for DOS was QDOS, for "Quick and Dirty Operating System"! https://en.wikipedia.org/wiki/DOS#QDOS (Seems rather unfortunate that they dropped the Q.)

Words per minute is an unfortunate measure of typing speed. The average length of letters differs between natural languages. For many computing activities it's even less representative: IDE shortcuts, punctuation in programming, etc.

It's unfortunate that '# foo' can mean "here's a command you need to run as root" or can mean "here's a comment about the next command". It's a recipe for confusion.
