Richard Silverman first touched a computer as a college junior in 1986, when he logged into a DEC-20, typed MM to send some mail, and was promptly lost to the world. He eventually resurfaced and discovered he had a career, which was convenient but somewhat disorienting, since he hadn't really been looking for one. Since earning his B.A. in computer science and M.A. in pure mathematics, Richard has worked in the fields of networking, formal methods in software development, public-key infrastructure, computer security, and Unix systems administration. He is a co-author on two O'Reilly titles: SSH, The Secure Shell (The Definitive Guide) and the Linux Security Cookbook, and author of the Git Pocket Guide.
