Relatedly, but I've always wished there were a series of books like, "I'm Already a Programmer but I'd Like to Learn ____"

Trying to pick up a book about a new programming language that is trying to explain the concept of an 'array' or whatever is annoying--I wish there was something to just lay out (still in a thoughtful and guided way) the concepts I needed to understand for that language based on already knowing several others.
