Don't miss the next issue!

Hi,

There are two Hackathons going to take place in close proximity in time, but quite far away. One in Berlin and the other one in New York. The former is the traditional annual QA Hackathon with a number of people flying in from various other places of the globe, therefore they still need help with some funding. I am happy to tell you that thanks to the growing number of advertisers in the Perl Weekly, and thanks to the people who contribute to the Perl Weekly via Gratipay I could use some of that money to sponsor the QA Hackathon! (The still need some more.)

In any case, enjoy the articles!

Accelerating Perl Tweet Facebook Google+
by Timm Murray (TMURRAY)

With the Raspberry Pi and other SoC (System on a Chip) devices it is time for Perl to start using accelometers. There aren't a lot of CPAN modules doing this, but Device::LSM303DLHC handling the LSM303DLHC chip can provide access to the readings. Let's see what can you do with it?

DBIx::Class::Report - generate ad-hoc dbic classes from SQL Tweet Facebook Google+
by Curtis 'Ovid' Poe (OVID)

Wouldn't it be nice if we could just take a chunk of arbitrary SQL and get a resultset from it? - Ovid asks and responds to himself with the release of DBIx::Class::Report. But when would you need it?

How you average numbers matters Tweet Facebook Google+
by Sinan Unur (NANIS)

We all know (or should know) that computations in a computer are not exact, but when Sinan puts it in front of us it is still very disturbing.


Testing

Test::More in serious need of review, be afraid! Tweet Facebook Google+
by Chad Granum (EXODIST)

Exodist is planning to release a new version of Test::More to CPAN. If that version breaks some a CPAN module, that CPAN module will become uninstallable. (Well, sort of.). Not only that. If the new version starts to report success when something failed then your code might be full of bugs while everything looks fine. In case you want to neither of this will happen, you can put some energy into looking at the changes and testing the new version.

The Perl QA Hackathon is still looking for Sponsors Tweet Facebook Google+
by Olaf Alders (OALDERS)

The QA Hackathon is an excellent event and dispite its name it is not only about Quality Assurnce. It became a more generice event when some of the people maintaining the core infrastructure needed for the Perl world get together for some much needed face-to-face conversation. I had the luck participating in two of such events, and now I had the privilage to even provide some funds to run the event. If you, or your company relies on Perl, this is a very good place to ensure the continous improvement of the whole ecosystem around Perl.

Dancer + Jasmine Tweet Facebook Google+
by Yanick Champoux (YANICK)

Absolutely awesome! Yanick had to test his Angular.js based code. So what did he do? He wrote a plugin for Perl Dancer. Jasmine is a behavior-driven development framework for testing JavaScript code. The new Dancer::Plugin::Test::Jasmine allows you to integrate the tests written in Jasmin with the test you write for your Perl-based back-end.

Loading module conditionally (and other options) Tweet Facebook Google+
by Steven Haryanto (SHARYANTO)

'use MyModule if $cond;' won't do what you might expect. So what can you do? (... and what < href="http://www.reddit.com/r/perl/comments/2zojah/loading_modules_conditionally_and_other_options/">Redditors think about this.)
