Building on the successful top-down approach of previous editions, this fourth edition continues with an early emphasis on application-layer paradigms and application programming interfaces, encouraging a hands-on experience with protocols and networking concepts.

    From a heart-shaped mangrove forest in New Caledonia to a flock of red ibises in Venezuela, from a caravan of camels in Mauritania to Mt. Everest and Mammoth Hot Springs, re nowned aerial photographer Yann Arthus-Bertrand presents nearly 200 striking color images that put our home planet in a whole new perspective. Produced under the sponsorship of UNESCO, the book is also a unique documentary record of the earth's fragile ecosystems at the dawn of the new millennium. Commentaries by noted specialists illuminate what we see-and explain exactly what we stand to lose as demographic pressures put more stress on the environment.

    Like Apple, it was an innovation machine that cranked out one must-have product after another. Led by its own visionary genius founder, Edwin Land, Polaroid grew from a 1937 garage start-up into a billion-dollar pop-culture phenomenon. Instant tells the remarkable tale of Land's one-of-a-kind invention-from Polaroid's first instant camera to hit the market in 1948, to its meteoric rise in popularity and adoption by artists such as Ansel Adams, Andy Warhol, and Chuck Close, to the company's dramatic decline into bankruptcy in the late '90s and its unlikely resurrection in the digital age. Instant is both an inspiring tale of American ingenuity and a cautionary business tale about the perils of companies that lose their creative edge.
