Google + GitHub. The former is how I've learned near everything over the past 5 years; I can't remember the last time I bought a programming/reference-type book. The latter is invaluable for browsing through others' code and I find it to be the fastest way to pick up new concepts. Why look through theoretical examples when you can look at real-world implementations?
