A developer friend sent me this article a while back (it’s older, so apologies if you’ve already seen it.)

It’s short, so you should read it for yourself, but the basic premise is that a missed hyphen (it was technically a mathematical figure called a vinculum, but whatever) in a hand-transcribed piece of code caused the 1962 Mariner Spacecraft to spin wildly out of control after launch. The engineers at NASA blew it up instead of risking a crash in an inhabited area.
Nothing I do leads to explosions. At least not literal explosions. Usually. I’m guessing nothing you do leads to disasters of this magnitude, either (despite what the project manager might say). I like to remember that whenever I get stressed or start taking myself too seriously.
