I owe much of my career to trying to set up Linux From Scratch two decades ago. While it’s a much better experience installing Linux nowadays, there’s a lot to be said for the experience spending your weekend debugging a system will give you.

yy to copy, dd to cut, p to paste. Need to move 5 lines at once? No problem, move to the first line and use d5d, and p to paste it. Vim gets a bad rap for being confusing, but it’s so fast to move text around once you get the hang of it.

That monologue (from one of the unambiguously “good” characters) about how it would be cruel to set the elves free, because of the joy they get from servitude? Even as a teenager, I recognised that as a messed-up sentiment, but my peers just said I was being too sensitive. Glad that you couldn’t let something like that slide nowadays.
