It was left out last week.

With a bit of delay, but the Catalyst Advent Calendar also went live.

When people use the keys() function on hashes, they quickly notice that the result is always the same. It takes a lot of energy to tell them they cannot rely on this order. With the recent changes in perl this will be much more obvious, making it easier to teach. This will also break the code of all those people who rely on the order despite what the documentation says. Breno G. de Oliveira explains it clearly and even show how the order that keys() returns changes even in current versions of Perl.

John McNamara described his adventure while adding macros. You can already use them and even add a button to invoke the macros.

'CGI might be out of favor for production sites, but for personal and internal applications, it's still the best choice for me.' writes and explains Steven Haryanto. Then in the comment section you'll see how PSGI wins even when you want to run as CGI.

One of the biggest problem I encounter when starting to clean up legacy code, is locating and eliminating duplicate code. For a long time I planned to write something to find them, but I never felt up to the task. I am glad Ovid started to work on this. I think this will be extremely useful in a lot of places.

A tutorial by Dominique Dumont to show how a configuration model can be updated.

Little boxes with module names and arrows pointing to the dependencies. It looks good when there are no more than 15 boxes, but how can it be displayed in a nice way when there are 1-200 dependencies?

Shlomi has released two now modules: SDLx-Betweener which allows for creating high-performance and smooth animations in SDL, and Test-XML-Ordered that can help testing XML files.

JT Smith, owner of both The Game Crafter and that of The Lacuna Expanse, you know, the open-source game, now explains how to build your own board game using Image::Magick.

This is the Hague Grant Carl Masak receives.

You might remember I mentioned the survey that Vyacheslav Matyukhin runs as his market research. The result are in now with lots of histograms.

by Carl Mäsak

As part of the Advent calendar Carl Masak explains how strangely consistent Perl 6 is, with the decision to change the behavior of the '|' operator in regexes to always match the longest string.

As 5.17.6 was released with hash randomization, several modules on CPAN started to get failures from CPAN smoking.

Apparently rand() isn't that random on Windows. There is also a call to remove some undocumented functions from the Perl core. If you are one of those few who might use such functions, please speak up now!
