From crashing computers to airplane crashes that claim scores of lives, the computer virus has become a growing plague of late twentieth-century life. This arresting and at times terrifying book tells us just how prevalent these software errors and defects are and how they are multiplying as more sophisticated computers become deeply embedded in our daily lives. As it explores the digital bugs that can cause such catastrophic results, it also offers a riveting portrait of the men and women who find and exterminate these viruses and glitches, whether they occur in pocket calculators or nuclear reactors. An entertaining introduction to the problems of creating reliable computer systems. – The Christian Science Monitor
