    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.

    But more than a temperament, being positive, we are told, is the key to success and prosperity. In this utterly original take on the American frame of mind, Barbara Ehrenreich traces the strange career of our sunny outlook from its origins as a marginal nineteenth-century healing technique to its enshrinement as a dominant, almost mandatory, cultural attitude. Evangelical mega-churches preach the good news that you only have to want something to get it, because God wants to "prosper" you. The medical profession prescribes positive thinking for its presumed health benefits. Academia has made room for new departments of "positive psychology" and the "science of happiness." Nowhere, though, has bright-siding taken firmer root than within the business community, where, as Ehrenreich shows, the refusal even to consider negative outcomes—like mortgage defaults—contributed directly to the current economic crisis.With the myth-busting powers for which she is acclaimed, Ehrenreich exposes the downside of America’s penchant for positive thinking: On a personal level, it leads to self-blame and a morbid preoccupation with stamping out “negative” thoughts. On a national level, it’s brought us an era of irrational optimism resulting in disaster. This is Ehrenreich at her provocative best—poking holes in conventional wisdom and faux science, and ending with a call for existential clarity and courage.
