I second using SRS--it's been very helpful for me to remember API minutiae or commands that I would otherwise have to google each time I needed it.
For programming topics, I also try to make sure I'm using the information. I unfortunately have too many cards about topics that I never actually used, and they are frustrating upon review because I never had some practical structure to place them into mentally. Don't waste time trying to memorize thing you don't ever use.
That said, SRS is good for memorizing trivia if you want to do that too. I've been using the Anki deck Ultimate Geography for a couple of months to memorize every country, capital, their flag, and location on a map. Useless, but kinda fun.
