> I don't want to have to be remembering that this thing I learned from that book can't be used on these projects because I don't have the right kind of license.
You don't have to. "This thing you remember" is an idea, and ideas are not subject to copyright, only expressions. Unless you're copy-pasting something out of a book this is a literal non-issue... and if you are in fact copy-pasting then frankly you deserve it since copy-pasting is the nadir of engineering practice. It is literally you turning your brain off and ingesting someone else's mistakes. Don't do that. Textbooks are for learning ideas, not lifting code.
