Tainted Perl: For Your Dirtiest Input
When writing a program that relies on data coming from outside sources, it is always a good idea to place checks on your data to make sure that there is no funny business going on.

Improved Exception Handling In Perl 5
Exception handling, or simply error handling, in Perl 5 has always been a matter of using eval on statements and then using conditional statements to check special variables for any possible error codes and responding appropriately.

An Alternative To LWP And LWP::Parallel
The benefit of using a Perl library is that you can instantly tap the knowledge and experience of one or more programmers who have already sought out and accomplished what you wish to harness from a given library.

Parallel HTTP And FTP Through LWP
I was recently working on a project where I needed to occasionally download many
different files from an internet server all at the same time, then process them as a whole.

Method Signatures Make Large Projects More Manageable
In many other languages, a function or method states upfront exactly what parameters it expects in order to successfully execute. Along with its name, this is called the "signature" of the function or method.

Revisiting Perl Regular Expressions Test
So a few weeks ago, I decided to put Perl's Regular Expression power to the test. The test was admittedly a quickly put together test, and thus had some flaws. I wanted to go back and revisit some of those flaws and re-evaluate Perl's status after I've cleared up these missteps.

Putting Perl Regular Expressions To The Test
Over my various years of experience in programming, it has been reiterated to me that Perl boasts amazing speeds in string manipulation. However, I realized that I had never really come across a study supporting this idea.

The MAIN Sub For Perl 6
Perl 6 very well may never fully supersede Perl 5 in the near future because they are engineered differently. Perl 5's maturity in the Unix-like environment make it a different tool compared to the current implementation of Perl 6 running on top of Parrot.

FILE I/O In Perl
An important aspect of Perl is it's ability to read from and write to files in the filesystem. Without this ability, it would be a lot harder to create log files or run search/replace scripts on your files, since there are few other languages that can even come close to Perl's ability to do so.

PERL Loops
There are several different flavors of loops available when coding in PERL. The four most commonly used loops are the while loop, the until loop, the for loop, and the foreach loop. Below you will find a quick tutorial on how each is used.

Perl's Staying Power Advertised Again
ActiveState is a company that specializes in dynamic languages, and whether or not you've heard of it, it's quite successful, with a long list of customers that includes impressive organizations like Cisco, HP, and Lockheed Martin. Which sets Perl professionals up for a nice surprise, because ActiveState's director of engineering has argued that Perl is here to stay.

Perl-AdWords Crisis Foreseen, Averted
It looks like the Perl community suffered a close call at the hands of a certain search giant. Although allowances have now been made, John Napiorkowski stated early yesterday, "on April 22nd SIGNIFICANT FUNCTIONALITY WILL PERMANENTLY BREAK FOR EVERY PERL APPLICATION USING GOOGLE ADWORDS API.".

Microsoft Angers CPAN Testers
Apple lovers, rejoice; Microsoft's standing with the overall Perl community took a serious turn for the worse last week. Indeed, while it might not be wise to speculate about motives (this could've been an accident), Microsoft effectively assaulted the CPAN Testers Reports site, and people aren't amused.
