Elizabeth Zwicky is a senior system administrator at Silicon Graphics and the president of SAGE (the System Administrators Guild). She has been doing large-scale UNIX system administration for 10 years and was a founding board member of both SAGE and BayLISA (the San Francisco Bay Area system administrators' group), as well as a non-voting member of the first board of the Australian system administration group, SAGE-AU. She has been involuntarily involved in Internet security since before the Internet worm. In her lighter moments, she is one of the few people who makes significant use of the "rand" function in PostScript, producing PostScript documents that are different every time they're printed.
