What kind of "technical minutiae" do you put in your Anki deck? I use Anki for Japanese study, but I've been thinking about doing more with it. Wasn't quite sure how to make useful tech flashcards... outside of memorizing as many powers of 2 as I could :)
Snippets from Python module docs. Objective-C APIs.
Basically, anything that I have to look up on StackOverflow.
E.g. os.path.relpath, -[NSString valueWithPointer:], -[NSString substringFromIndex:].
My loose heuristic is if I claim to be an X programmer, and some douche calls me out on an API call for language X in an interview, would I feel embarrassed saying I usually just look that up on Stack Overflow.
