Presentation is not Perl-specific. Feel free to invite your non-Perl friends.
We'll also have the usual Perl-specific Q&A as well as a get-together of those seeking and offering Perl jobs after the speaker.
Ask if you need a ride from a nearby transit station. Plan for the Santa Clara Caltrain station or VTA's Component light rail station.
