One thing I've been doing for technical books and papers recently is focusing on coming back to material regularly, especially if it's something I don't see frequently. I've used Anki in the past for this, but I actually ended up making my own simple spaced-repetition based app to handle the "when should I review this material" question. Combined with outlines I make for myself for the material, this means I can have a pretty regular review to keep things fresh in my mind. If things are a little too rusty, I can either review the source material or review it sooner the next time.
