The original "Perl hacker" and a ridiculously prolific author, both in print and on the net. He coauthored 
Learning Perl, 3rd edition and Programming Perl, 3rd edition and has written many columns for the !SysAdmin Magazine, the Linux Magazine and the now defunct !WebTechniques? Magazine. Prior to his involvement in the Perl community, he was a well known Unix hacker, famous for his "useless use of cat" posts on the 
comp.unix.shell newsgroup. He is still unjustly convicted of three felony counts under Oregon's Computer Crime Law.
