Reini Urban gave a presentation highlighting several of the features of the
cperl fork of the perl programming language.
Robert Stone delves into the cipher used by the Zodiac Killer in his

He ends by describing how the Zodiac Killer's cipher was solved.
Jim Bacon, Robert Stone, and Jocelyn Kirby gave short presentations on health
topics that can apply to developers.
Todd Rinaldo discussed the p5hack hack-a-thon this year in Amsterdam. He
described the purpose of the meeting and some of the decisions that came
out of the meeting.
The goal this meeting was to do some code reviews as a group. The idea was that
we would learn from each other's techniques and knowledge.
JD Lightsey suggested that the group make an attempt at the Perl Programming
challenge that OC.pm proposed for their May 2017 meeting. Eveyone was suggested
to make an attempt.
Todd Rinaldo has been working on the guts of Perl recently as part of the Perl

saw info about an attack on suid. The final presentation talked about Perl's minimum
Julian Brown ran a session where the attendees worked on the initial design
brainstorming for a project. We started with an idea proposed by Michael Davis
for a PSGI package that would set up a web service with minimal configuration.
Todd leads a session to hack on Perl code from the RT queue. The idea is
to find and fix at least one bug as a team.
