Hehe, so basicly what you're saying is that all linux users are hackers ... well, I would think thats a bit broad Wikipedia will give you the following definition: Currently, "hacker" is used in two main ways, one positive and one pejorative. It can be used in the computing community to describe a particularly brilliant programmer or technical expert (for example: "Linus Torvalds, the creator of Linux, is a genius hacker."). This is said by some to be the "correct" usage of the word (see the Jargon File definition below). In popular usage and in the media, however, it generally describes computer intruders or criminals. So, how you answer the original question really depends on what you put in the word hacking... Asuming you mean the popular version it would, as said before, it would mean a person with knowledge about computer security that uses these skills for evil purposes... If you then take the original meaning of the word it implies the most elite of all users, the ones with the greatest knowledge of all. These people are the reason technology exists, and should in no way be mistaken for people criminals ... Of course, you might argue that "evil hackers" bring about technological breakthroughs indirectly and thats obviously true too ...
