Matts (email not shown publicly) I work for MessageLabs [messagelabs.com] in Toronto, ON, Canada. I write spam filters, MTA software, high performance network software, string matching algorithms, and other cool stuff mostly in Perl and C.
Sitting in the speaker room at TPC here, and somebody across the room talking about advancing perl core just suggested that "Matt Sergeant is *the* guy to talk to about Perl and XML". I kept quiet. Funny.
