Issue #125 - 2013-12-16 - Snow, wind, no electricity, but plenty of Perl

latest | archive | by szabgab

Hi,

I don't know about your part of the world, but we just had a major storm that even covered the 'near-by' pyramids in snow. Part of the country is still without electricity after 4 days, but we were lucky as we did not have any power-failure and the sun came back too.

Anyhow, the Perlish Advent calendars supply many articles for you to read, but other people have not stopped to write either. You have plenty to read.

Enjoy!

Why I Don't Like Perl State Variables

Have you ever used the 'state' keyword in Perl? It is 'new' since 5.10 and it works like a 'static' variable in C. But do you really need it? Timm Murray from Wumpus Cave does not seem to like it.

Single process versus parallel tests

Ovid discusses the advantages of running tests in parallel - which are quite obvious (you get home earlier) - or maybe it isn't? He also describes his work on Test::Class, and Test::Class::Moose to make parallel processing a possibility there too.


CPAN

The correct Makefile.PL incantation

How to do you handle installation of CPAN modules on production servers if you don't have direct access to the Internet? (I'd be more worried if someone has access to the Internet and installs the latest from CPAN.)

This is an earlier screencast that can still be useful for you, it you are thinking about contributing to open source. As one of the readers pointed out: 'Your video was really eye opening. It showed me that I do not need to start very big as I was thinking, small contributions like that can really lead to big ones.'

Eliminate circular reference memory-leak using weaken

Because of the flexibility of Perl it is very easy to create circular references which, if not handled correctly, can easily cause memory leak. Here is how you can measure memory usage and how you can avoid circular references.
