Poe Curtis Conway Damian Chromatic - Perl Hacks: Tips & Tools for Programming, Debugging, and Surviving

chromatic works for O'Reilly Media, where he edits the free and open source web sites of the O'Reilly Network. In his spare time, he writes books such as this one.

Earlier this century, displaying his usual stellar sense of timing, Curtis "Ovid" Poe switched from mainframes to web programming in Perl and promptly watched the dot-com industry implode. Despite this minor setback and working for several currently non-existent companies, Ovid stuck with Perl and actually discovered he liked it. A frequent speaker at user groups and author of numerous CPAN modules and a popular Perl CGI course, Ovid is a Perl Foundation Steering Committee member and also heads the TPF grant committee.

Perl is also a language with a rich and varied community of experts, wizards, gurus, goofs, and ne'er-do-wells. A few of the most colorful characters[] contributed to this book.

Adrian Howard still hopes that Lisp and Smalltalk will take over the world, but in the meantime gets paid for playing with Perl and Ruby amongst other things. Agile fanatic. Testing bigot.

Joshua ben Jore came to Perl because he had to write a CGI app for a political campaign and he'd heard that Perl was best for that sort of thing. He stayed when he found out for himself how wonderful CPAN was. His latest projects have been working toward getting Lispy macros and lazy evaluation in Perl and learning what Prolog has to offer.
