Don't miss the next issue!


Again, lots of interesting articles this week. I was also busy building the first releases of DWIM Perl for Windows and publishing my first e-book about Perl. This a long journey for me, but I am making the first small steps which makes me quite happy.

I have been delaying the work on the back-end for the Perl Weekly for a while, but now, that I am pushing out the news items to 3 social networks I am doing a lot of repeated work. I'll have to put in more time in the code that hopefully will free me up some time reading the news. And coding. There must be some value in automating part of the work.

Anyway, let's see the news!

GSoC 2012

by Mark Keating

Europe is still freezing but Google and Mark Keating are already thinking about the summer and the code. The Perl Foundation wants to participate again which means you need to give ideas and volunteer as mentor.

by Gabor Szabo (SZABGAB)

This is the second DWIM release in a week. The first one was using Perl 5.12 but this one already uses the latest version of Perl and includes more than 400 modules from CPAN.


The unexpected case of -Mblib

by Reini Urban (RURBAN)

I think this is not the first time we catch Reini Urban eliminating bloat from our perl scripts.

Module review updates

by Neil Bowers (NEILB)

Neil Bowers is linking to the updated version of his report about defining constants. I really love the comparisons Neil is doing. I am looking forward to the day when his reports will be somehow available on the search interfaces of CPAN. E.g. when a module that he lists is being displayed there could be a link to his article.

Perl Data Language gets auto-parallelisation

The announcement about the new version of PDL made it into The H.

Dancer updates

by Sawyer X (XSAWYERX)

Sawyer X is, understandably, very enthusiastic about the community around the Dancer project and he also lists a number of changes that went into Dancer in the last 2 weeks. If you'd like to have the warm feeling of being in an open source community, this is for you.

The Values and Costs of Automation

chromatic makes a good point about automating parts of packaging CPAN modules or anything really.


Plat-forms 2012 : Perl on Amazon Web Services ?

by Laurent Dami (DAMI)

Laurent Dami (dami) started to prepare for the next Plat-forms competition that will take place in April in Berlin, but he is worried. Will the apparent lack of Perl on AWS make it hard for the Perl team to compete? Is there a lack of Perl on AWS? What do you think?

Annotations, Attributes, Traits

Peter Shangov describes how some languages (Java, C#, Python, Perl 5 and Perl 6) handle meta-data on objects and then offers some suggestion how he would like to write meta-data declarations in Perl 5.

Unicode and Passwords

by Curtis 'Ovid' Poe (OVID)

Do you allow strange characters in the username field? What about the password field? Don't have people enough problem typing with Caps-lock on by mistake? Check some of the issues with Unicode and passwords as Curtis (Ovid) Poe thinks about them.


CPAN Testers Summary - January 2012 - Bringing It All Back Home

by Barbie (BARBIE)

CPAN Testers is unique in its size and all that depends on a very small number of people. Mostly on Barbie, who wrote this monthly report.


Easy and Attractive Graphs with Chart::Clicker

chromatic shows a small example on the awesomeness of Chart::Clicker. I also like the module but I think last time I checked, I could not install it on Windows. I'll have to check that again and try to figure out what might be the problem so I can include it in DWIM Perl.


DistZilla from one newb to another

by Mark Allen (MALLEN)

Mark Allen shared his slides from the talk he gave at Very nice slides and I love the title too. I am sorry we don't have the actual presentation. Maybe at YAPC::NA?

by Moritz Lenz (MORITZ)

Moritz Lenz writes: The second task from the Perl 6 Coding Contest 2011 needs data structures not available in core Perl 6 to be solved efficiently.

Mini-Challenge: Write Your Prisoner's Dilemma Strategy

by Moritz Lenz (MORITZ)

Moritz Lenz invites us to another Perl 6 challenge. This time he describes the well known dilemma, offers some strategies, and provides the check-sum of his solution. It's like putting the solution in an envelop in a trusted third party. Very nice idea.


2012Q1 TPF Grant Proposal: Cooking Perl with Chef

by David Golden (DAGOLDEN)

$_ the default variable of Perl

by Gabor Szabo (SZABGAB)

IMHO for beginners it's quite hard to find explanation on what are the special variables of Perl. Especially $_ is confusing people and search engines. I hope my little contribution helps.

by Gabor Szabo (SZABGAB)
