Question

Can you be too old for trying to get good at programming? I don't want to be AWESOME but I want it to work somewhat decently. I'm 21 years old.

And I practically flunked 12th grade math. That's how bad I am.

Actually, it originates from a program called QED, originally written in the late 1960s by Butler Lampson and Peter Deutsch. Their version had the command SUBSTITUTE /x/ FOR /y/. Ken Thompson (of Unix fame) then wrote a version for MIT's CTSS system, and shortened the substitution command to just s/x/y/ - and, crucially, added regular expression support to it. Thompson later wrote Unix's standard editor ed, taking a lot of features from QED, including s//. It was the massive spread of Unix that so popularised this idiom.
