YAPC::EU 2013 Slides
See this link for the slides of talks given by Perl guru Jonathan Worthington in recently held YAPC Europe. Here is the brief list of talks:
All the talks are good but I personally liked the talk on Concurrency, Parallelism and Asynchrony in which he explains about Perl 6 thread system.
In future, I wish to attend some of these talks.
Enjoy the slides.
