Some hints for Ada

Part of the fun of reading Ada is figuring out all the wordplay, puns, literary allusions, double and triple entendres, and all the rest, purely on your own. But if you really need some help, you might take a look at AdaOnline, which has the first 26 chapters annotated. I must say, though, that every time you figure out one of Vlad's little puzzles, it is a satisfying thrill.
