Dr. Tim Maher's multi-decade career as a software professional includes stints at U.C. Berkeley as the Humanities Computer Consultant, at the University of Utah as a Professor of Computer Science, and at AT&T, Sun Microsystems, Hewlett Packard, and Consultix as a Course Developer/Lecturer on operating systems and programming languages. Along the way, he's taught UNIX, Linux, or Perl to many thousands of individuals—ranging from technology-phobic poets to corporate IT engineers. Tim founded Seattle's Perl Users Group, and served as its leader for six years. Many of its 400+ members contributed useful ideas to this book. In his spare time, he enjoys the natural beauty of the Pacific Northwest, where he lives.
