Ah. This site. I came across this when I was a kid - like 5-6 years ago - I had googled the term "how to become a hacker". This guy had opened my eyes then - I was 14 then. He still continues to do so. His links are still relevant and an amazing starting point for anyone who wants to learn.

One should probably keep visiting this page like every 6 months or so - just to check whether you are on the right track to learning.
