Cameron Newham lives in Perth, Western Australia. After completing a Bachelor of Science majoring in information technology and geography at the University of Western Australia, Cameron joined Universal Defence Systems (later to become Australian Defence Industries) as a software engineer. He has been with ADI for six years, working on various aspects of command and control systems. In his spare time Cameron can be found surfing the Internet, ballroom dancing, or driving his sports car. He also has more than a passing interest in space science, 3D graphics, synthesiser music, and Depeche Mode. Bill Rosenblatt is author of the the O'Reilly Nutshell Handbook(R) Learning the Korn Shell; co-author, with Deb Cameron, of Learning GNU Emacs; and a contributor to UNIX Power Tools. He is director of publishing systems at the Times Mirror Company in New York City and a columnist in SunWorld Online magazine on the World Wide Web. Bill received a B.S.E. from Princeton University and an M.S. and A.B.D. from the University of Massachusetts at Amherst, each in some variant of computer science. His interests in the computing field include multimedia databases, electronic publishing, and object- oriented systems. Outside of the computing field, he's interested in jazz, classical music, antique maps, and Sherlock Holmes pastiche novels. Bill lives on the Upper West Side of Manhattan. He wishes his landlord allowed pets so that he could truthfully claim to have a dog and cat with suitably droll names like Coltrane and Ravel.
