Mark Jason Dominus has been programming in Perl professionally since 1992, when he was a UNIX sysadmin with the University of Pennsylvania Department of Computer and Information Sciences. Mark is an occasional contributor to the Perl Core, and is the author of the standard perlreftut man page as well as the Tie::File, Text::Template, and Memoize modules. From 1999-2001, Mark was the managing editor of the www.perl.com website. He was also a columnist for The Perl Journal for several years. All of his articles for TPJ have been reprinted in Computer Science and Perl Programming: Best of the Perl Journal, from O'Reilly and Associates. Mark's other Perl-related articles have appeared in magazines such as Wiredand IEEE Software. Since 1998, Mark has been a professional Perl trainer. In addition to speaking at conferences such as YAPC, the O'Reilly Open Source Conferences, Usenix, and LISA, he has given training courses for large companies and organizations, including Morgan Stanley, IBM, Bristol-Myers Squibb, and the U.S. Air Force. Mark's work on Rx, a Perl regular expression debugger, won the 2001 Larry Wall Award for Practical Utility.

"It's well written.everyone who claims to be an expert ought to read it.these techniques allow programmers to accomplish far more than they're used to." - Gregory V. Wilson, Dr. Dobb's Journal, November 2005 "It is, quite simply, one of the best books on programming I have read for a long time." - Martin Schweitzer, Computing Reviews, Association for Computing Machinery, July 2005 "Mark Jason Dominus has hit his mark with Higher Order Perl. It is a very informative book that is a must read for Perl programmers who want to take their skills to the next level." - Mark Rutz, Linux Journal, November 2005 "Higher-Order Perl is one of the Perl books that should have a place on the bookshelf of every Perl programmer. It offers an in-depth understanding of important programming techniques and fundamental concepts. The chapter on parsing alone is worth the price of this book. I do not know a better text about parsing in Perl." - Reinhard Voglmaier, Unix Review, November 2005 "Higher-Order Perl is the most exciting, most clearly-written, most comprehensive, and most forward-looking programming book I've read in at least ten years. It's your map to the future of programming in any language." - Sean M. Burke, Leading Programmer, Comprehensive Perl Archive Network (CPAN) "There are lots of book that teach you new Perl modules or techniques. This book goes beyond that and teaches a new way to think about Perl programming." - Peter Norvig, Google Inc. "As a programmer, your bookshelf is probably overflowing with books that did nothing to change the way you program... or think about programming. You're going to need a completely different shelf for this book. While discussing caching techniques in Chapter 3, Mark Jason Dominus points out how a large enough increase in power can change the fundamental way you think about a technology. And that's precisely what this entire book does for Perl. It raids the deepest vaults and highest towers of Computer Science, and transforms the many
