NYC Perl Hackathon 2015 has its own Mini CPAN PR Challenge
Here's how it works:
A list of CPAN distributions will be published in the Mini CPAN PR Challenge project page one day before the hackathon begins.
On the day of the Hackathon, Hackathon participants will choose 1 distribution and start hacking on it.
If you are new to this challenge, we have a list of suggestions to help you get started on your assignment.
