Don't miss the next issue!


this is the first day of school in many countries and kids roam the streets determined to improve their knowledge. Or at least to meet some friends they have not seen for a while.

It's a bit like a New Year. You can have all kinds of 'resolutions'. I hope we'll see tons of new and exciting articles about Perl, and how it is used to solve various 'real-world' problems.

Oh and the Swiss Perl Workshop is this week-end!

Enjoy! ~szabgab

The 11 Most useful Perl sites

It started out as a reminder of rarely used, but important sites, but turned into a list much longer than the title suggests.

Data::Dumper Debugging

by Toby Inkster (TOBYINK)

Pry, the new tool from Toby Inkster, allows you to stop execution of a script and drop in a REPL at the 'point of interest' of your choice.


Replacing hash keys with values does not a translation make

by Sinan Unur (NANIS)

Sinan Unur (Sinan) thinks the Turkish translation of the Perl Maven pages actually harm would-be programmers. Naturally I disagree, but he has a point: Bad translations can indeed harm people. The only thing I can do is to suggest to collaborate with other translators to improve the text. It is available in GitHub

Context dependence in Turkish

As a follow-up to the previous post, and after patching the Turkish translation, Sinan goes on discussing context sensitivity in the Turkish language.


Continous Integration with Travis CI and Github for Distzillians

You can configure your GitHub repositories to run your test automatically every time you push out code or even if someone sends a pull-request. By this you can have our module tested on various versions of perl long before you release a new version. Very useful!

brian d foy answer the question "How do I add the elements of a file to a second one as columns using Perl?"

Facing the music with Perl

Collecting meta-data from music files after making sure they are unique. Code with explanation by brian d foy.


Yearly boards and fallen authors

by Philippe Bruhat (BOOK)

Philippe Bruhat (BooK) likes games and now with his new site,, he has a lot of new ground to create competitions. This one is showing how long each person will release a CPAN module every week within a year. A major limitation that I can see is that this board only handles years according to the Gregorian calendar. In any case this is for the CPAN heavy-weights. If you have ideas for other competitions to encourage more ad-hoc contributions, or if you have any other idea, please open a ticket!

Link to public version control system (GitHub or otherwise)

Having the META files include a link to your public VCS will let MetaCPAN to link to it and will make it easier for others to send patches.

Finding all Plack Middleware or Perl::Critic Policies

It is probably just me being too slow to learn this, but apparently you can list all the modules in a given name-space by preceding it with 'module:'. So it is quite easy to list all the Plack::Middleware, all the Perl::Critic::Policy modules, or all the plugins for Dancer, Mojolicious, or Catalyst.


Outreach Program for Women: Mentor's Summary

Randy Stauner describes his mentoring of Pattawan Kaewduangdee under the join The Perl Foundation-GNOME Foundation program for women. She was working on MetaCPAN and wrote about it regularly.

Perl 6

Try rakudobrew and play with concurrency

by Curtis 'Ovid' Poe (OVID)

Apparently, Ovid got excited by recent improvement in Rakudo, tried it and even wrote about it. Moore's law is coming to an end. Easy-ish threading is the solution.

Announce: Rakudo Star Release 2014.08

This release comes with support for the MoarVM backend along with experimental support for the JVM backend.
