Jeffrey Friedl has been an engineer for Yahoo! Finance for five years, using
mostly Perl to process volumes of financial news and data. Prior to
that, he spent eight years doing kernel development for Omron Corp of
Kyoto, Japan.
He's spent the last two years researching regex-related issues of C#,
MySQL, Perl, PHP, Python, Ruby, Tcl, VB.NET, and many more, for the
second edition of O'Reilly's Mastering Regular Expressions. He
is sporadically active as a Perl core developer. He spent much of early
2002 pestering Jarkko Hietaniemi about Unicode problems in betas of
Perl5.8, but perhaps redeemed himself by contributing some core patches
as well.
He lives with his wife in Cupertino, California, and is currently
awaiting the Fall-2002 rollout of their first "software project"
together.
