I used to think that there was a conference season and that it took place in the summer. Now in the Perl world we have so many grass-root events taking place that the whole year is our conference season.
Towards the end of the month the Birmingham Perl Mongers are hosting a 3-day QA Hackathon. This is a follow-up to the successful QA Hackathon that took place in Oslo last year. This isn't a conference, in the traditional sense, but a place for people involved in QA, testing, packaging, and CPAN to get together and code together.
All this in just three months. It's going to be a fantastic year for Perl conferences.
