About the Author

With a background in journalism and farming, Steve Talbott has worked for the past 12 years in technical documentation. Prior to joining O'Reilly & Associates he managed the Technical Publications Group at Concurrent Computer Corporation, and before that was responsible for the development of computer-based documentation tools at Concurrent. In his editorial position at O'Reilly, Steve develops new titles across the company's product line. He has focused on 3D graphics and software standards. Avocationally, Steve pursues an interest in the broader social and cultural implications of computers. Over an eight-year career in computer documentation Andrew Oram has evolved from a proponent of the congenial user-oriented approach to a fanatic on the subject of explaining models and internal operations so as to empower computer users. He was not prepared by his education (which included music and social work) for the philosophical and pedagogical demands of this role, but seems to have fallen into it. His technical writing career encompasses Honeywell Information Systems (now Bull), CSPI (still itself, incredibly), MASSCOMP (now Concurrent Computer Corporation), and currently O'Reilly & Associates, where he is an author. He also once worked as a college instructor teaching PDP-11 assembly language. Topics of his manuals include network administration and programming, array processors, languages, debuggers, and real-time programming---in fact, writing about shell commands in Managing Projects with make has proved to be a relaxing break. His recent research focuses on making user documentation verifiable through the same quality-assurance process used on other components of a computer system. Whenever he gets a free moment away from his three-year-old, seven-year-old, and other commitments, he works with Quality Assurance teams on this project and publicizes it through articles and conferences.
