    Not an easy job, given the lingering resonance of Serbia's role in the 1990s Yugoslav wars in the world’s news bulletins. To this day, the words "Serbia" and "atrocities" are linked in the minds of many. This study of both Djokovic and Serbia paints two powerful portraits. It traces the story of the boy from modest surroundings, telling how he met the woman who not only taught him tennis but how to deal with life as a high-profile icon, charts his battle with illness and his relationship with a volatile father, and how his on-court accomplishments have made his country proud. But it also tells the story of Serbia, pulling no punches about its role in the 1990s wars but offering a sensitive interpretation of the hopes and aspirations of a people with a troubled past. This book weaves together these sporting and geo political strands to present a sensitive portrait of a man and his people, and how determination married with sensitivity can create a sporting statesman.

    The gold standard for attaining security is cryptography because it provides the most reliable tools for storing or transmitting digital information. Written by Niels Ferguson, lead cryptographer for Counterpane, Bruce Schneier's security company, and Bruce Schneier himself, this is the much anticipated follow-up book to Schneier's seminal encyclopedic reference, Applied Cryptography, Second Edition (0-471-11709-9), which has sold more than 150,000 copies. Niels Ferguson (Amsterdam, Netherlands) is a cryptographic engineer and consultant at Counterpane Internet Security. He has extensive experience in the creation and design of security algorithms, protocols, and multinational security infrastructures. Previously, Ferguson was a cryptographer for DigiCash and CWI. At CWI he developed the first generation of off-line payment protocols. He has published numerous scientific papers. Bruce Schneier (Minneapolis, MN) is Founder and Chief Technical Officer at Counterpane Internet Security, a managed-security monitoring company. He is also the author of Secrets and Lies: Digital Security in a Networked World (0-471-25311-1).

    He tells his life story, from growing up in the Midlands to all the excesses of glam rock, and is currently busy carving out a new career for himself in the TV sitcom, The Grimleys.

    Doron Swade, technology historian and assistant director of London's Science Museum, investigates the troubles that plagued 19th-century knowledge engineers in The Difference Engine: Charles Babbage and the Quest to Build the First Computer.The author is in a unique position to appreciate the technical difficulties of the time, as he led a team that built a working model of a Difference Engine, using contemporary materials, in time for Babbage's 1991 bicentenary. The meat of the book is comprised of the story of the first computing machine design as gathered from the technical notes and drawings curated by Swade. Though Babbage certainly had problems translating his ideas into brass, the reader also comes to understand his fruitless, drawn-out arguments with his funders. Swade had it comparatively easy, though his depictions of the frustrating search for money and then working out how best to build the enormous machine in the late 1980s are delightful.It is difficult--maybe impossible--to draw a clear, unbroken line of influence from Babbage to any modern computer researchers, but his importance both as the first pioneer and as a symbol of the joys and sorrows of computing is unquestioned. Swade clearly respects his subject deeply, all the more so for having tried to bring the great old man's ideas to life. The Difference Engine is lovingly comprehensive and will thrill readers looking for a more technical examination of Babbage's career. --Rob Lightner
