Articles
Relationships with optional foreign key values (DBIx::Class)
http://bit.ly/1hP7CgJ
David Schmidt (davewood) explained the problem: "Imagine two related tables
'human' and 'cat': A cat belongs to a human but when the human dies the
cat can continue to roam freely." I am not a cat-person, but based on all
the information I gather on the web, and there is no shortage of
information about cats, I wonder if the word 'belongs' can even apply
there. Anyway, the problem with the database still remains.

Perl - understand List, unary operation and array in scalar context
http://bit.ly/1hP7CgK
Probably in response to the article of Dave Cross ("http://bit.ly/1hwZi5f")
from last week (though unfortunately he does not link there), Celogeek
gives a few examples for list and scalar context.
--------------
=============
Testing
Two testing heavy weights in one issue! Nice.
Merry Christmas! Parallel testing with Test::Class::Moose has arrived
http://bit.ly/1cB75Oq
If you were looking for a Christmas present, here is one from Ovid. He says
he can make your test 24 times faster. Or, at least, the one he had was
made so much faster. Oh, and he is using Parallel::ForkManager. Luckily,
I just fixed a stupid bug there that I introduced a while ago.
--------------
Profile Your Tests (One Test Class Per File)
http://bit.ly/1hP7DBj
chromatic agrees with 90% of what Ovid write in a different article
("http://bit.ly/1hP7CgN") but does not tell us the 10% he disagrees with.
But then he goes on explaining why he thinks using Test::Class was
probably a good choice in their case. If you write tests, and I really
hope you do, then it is worth reading these articles and thinking about
the implications.

=============
Code
Graphics::Potrace
http://bit.ly/1cB764N
Potrace is a tool to transform bitmaps into vector graphics.
Graphics::Potrace, written by Flavio Poletti provides the Perl binding to
it.

Pjam - continues integration for Perl, using Pinto.

Christmas Eve Obfu
http://bit.ly/1cB764S
If it's Christmas, you need a tree. A tree made of Perl. See what Toby
Inkster had in mind.

UAV::Pilot v0.8 Released - Now Supports Wumpus Rover
http://bit.ly/1cB7653
The Wumpus Rover was built on top of an old RC car using a Raspberry Pi and
an Arduino, and controlled by Timm Murray via his UAV::Pilot module. The
article comes with a video, that was also featured on the Perl TV
("http://bit.ly/1hP7Cxe"). If you are looking to build something by
yourself, or with your kids, this can be a great project.
--------------
Perl and Me, Part 4: A Worthy Program, Exceedingly Well Read
http://bit.ly/1hP7DBn
Buddy Burden continues telling his story. This time he explains why code
readability is so important, and how that does not mean using a limited
subset of the language.
--------------
=============
Web
Perl Jedi, Hello World !
http://bit.ly/1cB74do
Jedi is a web application framework with no DSL. Celogeek, who put on his
Yoda-face when creating Jedi, has started a series of articles. This is
the first part and he already published a follow-up on the session plugin
("http://bit.ly/1hP7DBo"). I certainly like the fact that he did not just
put it on CPAN and waited for the hordes of people to start using it. In
these days one has to explain even a Jedi.

existing module and shows how to write and run unit-tests for the module.
