Cliff Stoll describes the origins of his bestselling book, "The Cuckoo's Egg," which detailed his efforts to catch a hacker breaking into Lawrence Berkeley Lab's Unix systems in 1986. He recounts the "scary" experience of explaining the Arpanet and TCP/IP protocols to a group of elite physicists at Luis Alvarez's house. Stoll notes that passing this rigorous examination gave him the "license to do stupid things" for the rest of his career.
