Anki is killer for vocabulary (and I've heard health science), since this involves a long tail of terms you might need to recall with somewhat low frequency. Otherwise, if you use something frequently, you won't need effort to recall it. In programming, I've found that putting in the effort to make flashcards can help guide understanding. - Understanding some thing is easier if you can recall some basic facts of the domain. And at least, taking the time to break some concept down into basic facts will show what you're familiar with and unfamiliar with.
