This 25th anniversary edition of Steven Levy's classic book traces the exploits of the computer revolution's original hackers -- those brilliant and eccentric nerds from the late 1950s through the early '80s who took risks, bent the rules, and pushed the world in a radical new direction. With updated material from noteworthy hackers such as Bill Gates, Mark Zuckerberg, Richard Stallman, and Steve Wozniak, Hackers is a fascinating story that begins in early computer research labs and leads to the first home computers. Levy profiles the imaginative brainiacs who found clever and unorthodox solutions to computer engineering problems. They had a shared sense of values, known as "the hacker ethic," that still thrives today. Hackers captures a seminal period in recent history when underground activities blazed a trail for today's digital world, from MIT students finagling access to clunky computer-card machines to the DIY culture that spawned the Altair and the Apple II.

When something works well, you can feel it; there is a sense of rightness to it. We call that rightness beauty, and it ought to be the single most important component of design. This recognition is at the heart of David Gelernter's wittily argued essay, Machine Beauty, which defines beauty as an inspired mating of simplicity and power. You can see it in a Bauhaus chair, the Hoover Dam, or an Emerson radio circa 1930. In contrast, too many contemporary technologists run out of ideas and resort to gimmicks and features; they are rarely capable of real, structural ingenuity. Nowhere is this more evident than in the world of computers. You don't have to look far to see how oblivious most computer technologists are to the idea of beauty. Just look at how ugly your computer cabinet is, how unwieldy and out of sync if feels with the manner and speed with which you process thought. The best designers, however, are obsessed with beauty. Both hardware and software should afford us the greatest opportunity to achieve deep beauty, the kind of beauty that happens when many types of loveliness reinforce one another, when design expresses an underlying technology, a machine logic. Program software ought to be transparent: it should engage what Gelernter calls "a thought-amplifying feedback loop," a creative symbiosis with its user. These principles, beautiful in themselves, will set the stage for the next technological revolution, in which the pursuit of elegance will lead to extraordinary innovations
