Issue #116 - 2013-10-14 - Perl TV launched

latest | archive | by Gabor Szabo
Don't miss the next issue!


I am sorry for sending this edition so late, I was busy trying to launch the new Perl TV site. There are plenty of interviews, talks and presentation posted on YouTube and other video sites, but very few people know about those. I think it will be nice to share these videos. So the Perl TV site will post a new video every day. You can follow it via its Atom feed.

In other news, it turns out the Portuguese Perl Workshop was rescheduled to October 24-25. Please make sure you arrive on the right days :).

Enjoy the articles!
