I have a solution for this: Anki. Over the past few months I've created decks for topics ranging from electronics to mechanics to convex optimization.
They're simple Q&A format and have tags, making them searchable. Best part? Export it all to the Android app. So when I'm on the bus reading a paper and I forget how to transform a second order cone program into a semidefinite program, it's a 5 second process: search "socp,sdp,transform" boom, done.
The catch, of course, is you need to take the extraordinary amount of time to sit and digitize it all. And I'm barely 10% done what I've wanted to. Still, a bit everyday pays dividends.
