Adolescents are wise in the psychology of computer games and Middle Earth. They live in a world they can't control, in a body that seems increasingly alien. To them the computer world is soothing, offering reassurance through mastery. Just as each episode of "The Lord of the Rings" presents a danger and each has its resolution, so many adolescent boys move from one block of intransigent code to another, from one screen to the next, declaring victory as they go. But this distinction is about more than gender; it is about ways of looking at the world — real, imagined or computer-generated. Some pioneers of computing had a style of working that rewarded risk. They spoke of programming itself as though it were a dangerous quest. At M.I.T. computer hackers even had a name for it: "sport death." To pull back from the impending doom of a system crash required near magic, an almost empathetic knowledge of the intricacies of code. For this community, a certain bravado came to be seen as valuable, even necessary, beyond the world of programming.
