This can be taken to almost any subject you want. I do this with more general programming books. Examples of books I've done this with are Programming Pearls/More Programming Perls (Jon Bentley), Code Complete (Steve McConnell) and The Pragmatic Programmer (Andrew Hunt/Dave Thomas).

These are relatively small books (apart from Code Complete), and consisting of multiple easily digested parts. You do a small part each day, and before you know it you've absorbed a lot of knowledge.
