Don't miss the next issue!


First of all, let me apologize to those who are reading the text version of the newsletter. Due to a bug and my impatience, last the newsletter was missing the text version. Sorry for that.

Advent is here! While you might not celebrate the Christian Advent, it became a tradition in the Perl community to create Advent calendars. This means 24 articles in 24 days. We won't be able to cover all the articles published in the Advent calendars, but you can see a list of them in the Advent section. You can also follow the one maintained by Len Jaffe who has been collecting the various Advent calendars for years. Which brings me to another point. All of these calendars are written by volunteer contributors. Not necessarily core developers. You could also contribute an article!

More adventures in test failures Tweet Facebook Google+
by Sinan Unur (NANIS)

Sinan Unur keeps bumping into test failures while using perl 5.20.1 compiled with Visual Studio 2013 CE. I wonder if he is also sending bug-reports or even patches to fix these issues, or is he trying to get people understand the problems and fix them by themselves? Have you sent any patches (or pull requests) recently?
