Now with this experience, I find myself no closer to actually hacking anything. I know programming, so what? I have no clue how computer security works, never mind trying to exploit it! I have completed most of the Basic tasks, that's true, but I don't see how opening the source code of a page up and looking up the password has anything to do with real website hacking. This has really been irritating me, so I apologise if I come over as wanting to criticise the challenges - that's not my aim.
I guess my request to you guys would be to point me in the right direction, what to learn, how to learn it. Any links to useful documents would be massively appreciated.
