Hi there,

It seems the past week brought us fewer articles but nevertheless I found a few interesting ones.

The Perl Weekly was mentioned in the DevOps Weekly that brought us a few more subscribers.

I also found out that the subscribe button of the Perl Weekly was partially broken due to the same-origin policy enforced in some browsers more than in others. I fixed this now. I hope.

Now to the posts:

Flavio Poletti introduces his 'yet to be fully released' module to make it easy to handle the environment in DotCloud

Testing with sqlite

Anthony Pallatto (actualeyes) suggests to use SQLite in your testing environment instead of the database used in production. Using SQLite certainly has some advantages but there is the great danger of anything in production being different from the testing environment. SQLite can be good to reduce the complexity to setup development and testing environments but just as you do full test cycles every now and then (preferably frequently) so should you use a system as close to the deployment environment as possible.

Perl says 'Hello I-Programmer'

This is the first article I wrote to the web site. It probably won't be an earth shattering experience for you but it is my first one on I-Programmer. It is mostly there so I'll have an in-house article to refer to on how to start using Perl when I write more complex examples.

Lessons from running Perl Weekly for the first 6 weeks

by Gabor Szabo (SZABGAB)

This is another article I wrote, this time on my own blog, describing my experience with this list. It might be interesting to you if you'd like to look a bit at the details. I am also comparing the experience with that of Peter Cooper who runs the Ruby Weekly which was the inspiration to this newsletter.


Parrot is a foundering project on top of a wonderful vision.

Christoph Otto took off the gloves and started to describe how he wants Parrot, and more importantly the Parrot development process to change. This is a link to the opening message on the parrot-dev mailing list with many important responses.

Parrot, the Smoke Clears

Andrew Whitworth (aka Whiteknight on black background) takes the above e-mail discussion and writes a lengthy article about the interaction between the Parrot and the Rakudo (Perl 6) projects. Compared with the JVM and the CLR how they have a primary language but how they have started to be good targets for other languages as well.


Parameterized Roles with MooseX::Declare

Florian Ragwitz (rafl) shows the new, undocumented feature of MooseX::Declare and points to the Github repository where you could help improve the documentation.

Going Postal (with Dancer)

by Yanick Champoux (YANICK)

Yanick Champoux (yanick), in his usual colorful way, describes how he wrote a plugin for Dancer to handle postal fees in Canada. I am sure if it can be done in Canada it can be done elsewhere as well. The nice thing is that he even provides a way to save money. Even if not on the actual postal fees.

Simple Mojolicious RSS feed

Mark Meyer (mark) gives a nice and simple example on how distribute updates about changes in a system with a very simple Mojolicious application. If only the fonts were bigger on this blog...

How to Run a Long Background Process in a Web App

by Peter Thoeny

Peter Thoeny from Twiki explains a way how to handle long running processes in response to browser requests. This is an ongoing question that trips a lot of people who want to build a web interface to an existing system. Eg. a build machine. Unfortunately this solution does not work on Windows.

Memory::Usage - Aktuelle Speichernutzung (Current memory usage) in German

by Thomas Fahle (TOMFAHLE)

Thomas Fahle gives a code example and explains (in German) how to check what is the memory usage of the current process. So a script or application could report its own memory usage. (This is also Linux/Unix only.)

Perl 6

'nom' branch is now default, release status

by Patrick R. Michaud

Patrick Michaud (pmichaud) provides us with an update on the status of the Rakudo development. The next release is further delayed but the good news that it will already come from the new 'nom' branch that is the new rewrite of the whole engine.

-n and -p

by Carl Mäsak

This is the third part of the series Carl Mäsak has written showing us how the -n and -p parameters work in Rakudo Perl 6. The others are on his blog as well.


Fancy syntax checking with Padre

Ahmad M. Zawawi (azawawi) shows a screenshot of his new addition to Padre, the Perl IDE. You don't even have to wait for the next release of Padre to use that. You can run it directly from the development environment.
