About the Authors

Brian Jepson is an O'Reilly editor, programmer, coauthor of all editions of Mac OS X for Unix Geeks, and coauthor with Dave Taylor on the Jaguar and Panther editions of Learning Unix for Mac OS X (O'Reilly). He's also a volunteer system administrator and all-around geek for AS220, a nonprofit arts center in Providence, Rhode Island. AS220 gives Rhode Island artists uncensored and unjuried forums for their work. These forums include galleries, performance space, and publications. Brian sees to it that technology, especially free software, supports that mission.

Ernest E. Rothman is an associate professor of mathematics and chair of the Mathematical Sciences Department at Salve Regina University (SRU) in Rhode Island. Like Brian, Ernie has coauthored every edition of Mac OS X for Unix Geeks. He holds a Ph.D. in Applied Mathematics from Brown University and held positions at the Cornell Theory Center in Ithaca, New York, before coming to SRU. His academic interests are in scientific computing, computational science, and applied mathematics education. As a longtime Unix aficionado, Ernie has enjoyed tinkering with Mac OS X since the day it was first released. You can keep abreast of his latest activities at http://homepage.mac.com/samchops.
