The second edition of the Camel Book is more than 600 pages long and full of excellent instruction and sound advice. Topics include all the good stuff from the first edition plus Perl 5 features such as nested data structures (ever made a hash of arrays of hashes?), modules, and objects. From "Howdy World" to making your own modules, this book has it all.

For many readers, Jack Ryan embodies the essence of the modern American hero. Morally centered, disciplined, humble yet powerful, Ryan (and his onscreen incarnations in Alec Baldwin and Harrison Ford) has made Tom Clancy one of the most popular writers in the world. But as Clancy has constructed the Ryan mythology, he has quietly established Ryan's shadow double, John Clark. Appearing in The Cardinal of the Kremlin, Clear and Present Danger, and Without Remorse, Clark has many of Jack Ryan's most appealing traits, but he is also a darker figure embodying the more paranoid sensibilities of the late '90s. As is made clear from the opening pages of Rainbow Six, ex-Navy SEAL Clark and his colleagues believe violent, deadly force to be the best deterrent for terrorism.

Clark (a.k.a. Rainbow Six) has left the CIA to create an England-based organization code-named "Rainbow." Its mission: deploy an elite squad of American operatives combined with handpicked British, French, and German agents to stop terrorism in its tracks. Rainbow's emergence could not be more timely: in quick succession, the force diffuses three attempted terrorist actions. But Clark becomes suspicious when Russian agents suddenly show interest in Rainbow's work.

Rainbow Sixappeals on all the levels that Clancy fans could hope for. The Rainbow operatives, from Navy SEALs to German mountain-leader school graduates, are rendered to inspire with their physical and mental prowess. The book is infatuated with the latest gadgets for scrambling, transmitting, and decoding secrets. And, in a carefully woven narrative that simultaneously traces the Rainbow team, a former KGB agent named Popov, the Australian Olympic security team, and a sinister group of American scientists, Clancy artfully reveals the mystery of "Shiva" at the center of the novel. How does Clark measure up against Jack Ryan? He may be the perfect hero for a world with hidden villains. —Patrick O'Kelley

Love him or loathe him, Mr. Microsoft is certainly an influential voice in the modern business world and The Road Aheadis definitely an important addition to any business library. Gates' description of the beginnings of the information age, while somewhat over-emphasizing his own contributions and downplaying those of his competitors, is nonetheless as clear and enlightening as any in print today. Likewise, his view of the digital future—from hardware to software and education to entertainment—should be read and studied by all who use technology in their business today or plan to use it on the road ahead.
