I have heard a lot about this operating system. But since I am coming from Windows XP and MAC OS X, it is hard for me how to take advantage of the system enough to hack into another system, because this is the equivalent of turining a popular single player game into a multiplayer game, which to me is impossible since only the software companies have nough time to set up the computer to do that. I would also like to understand how somebody can break into someones machine using a programming language. I know it would be impossible for you to help me understand these problems I have in one post, but maybe you could recomend a good book or text file. Thanks!
