Once upon a time Linus Torvalds was a skinny unknown, just another nerdy Helsinki techie who had been fooling around with computers since childhood. Then he wrote a groundbreaking operating system and distributed it via the Internet -- for free. Today Torvalds is an international folk hero. And his creation LINUX is used by over 12 million people as well as by companies such as IBM.

Now, in a narrative that zips along with the speed of e-mail, Torvalds gives a history of his renegade software while candidly revealing the quirky mind of a genius. The result is an engrossing portrayal of a man with a revolutionary vision, who challenges our values and may change our world.

You may be a hacker and not even know it. Being a hacker has nothing to do with cyberterrorism, and it doesn’t even necessarily relate to the open-source movement. Being a hacker has more to do with your underlying assumptions about stress, time management, work, and play. It’s about harmonizing the rhythms of your creative work with the rhythms of the rest of your life so that they amplify each other. It is a fundamentally new work ethic that is revolutionizing the way business is being done around the world.

Without hackers there would be no universal access to e-mail, no Internet, no World Wide Web, but the hacker ethic has spread far beyond the world of computers. It is a mind-set, a philosophy, based on the values of play, passion, sharing, and creativity, that has the potential to enhance every individual’s and company’s productivity and competitiveness. Now there is a greater need than ever for entrepreneurial versatility of the sort that has made hackers the most important innovators of our day. Pekka Himanen shows how we all can make use of this ongoing transformation in the way we approach our working lives.
