Symbol Table Manipulation
One of the most dramatic advantages of dynamic languages is that they provide access to the symbol table at run-time, allowing new functions and variables to spring into existence as you need them. Though they're not always the right solution to common problems, they're very powerful and useful in certain circumstances. Phil Crow demonstrates how and when and why to manipulate Perl's symbol table.

A Plan for Pugs
Want to write actual working Perl 6 code? A month ago, it would have been difficult. What a difference February made. Autrijus Tang and a loyal cadre of Perl and Haskell people have developed an amazingly complete Perl 6 implementation in a few short weeks. chromatic recently caught up with Autrijus on #perl6 to learn more about the project.

Perl and Mandrakelinux
Perl is a fantastic tool for system administrators. Why not use it for building administrative applications? That's just what Mandrakelinux does! Mark Stosberg recently interviewed Perl 5.10 pumpking and Mandrake employee Rafael Garcia-Suarez about the use of Perl for graphical applications.

Building a 3D Engine in Perl, Part 3
The ultimate goal of all programming is to be as unproductive as possible--to write games. In part three of a series on building a 3D engine with Perl, Geoff Broadwell explains how to manage the viewpoint and how to achieve impressive lighting effects with OpenGL.

Perl Code Kata: Testing Databases
Testing simple code is all well and good, but what happens when your real code has to work with external programs, such as databases? How do you test your code adequately without going crazy writing scaffolding that has no chance of working anywhere but your test box? Stevan Little suggests that DBD::Mock can round out your test toolbox nicely in this Perl Test Kata.

Throwing Shapes
Sometimes data processing works best when you separate the application into multiple parts; this is the well-loved client-server model. What goes on between the parts, though? Vladi Belperchinov-Shabanski walks through the design and implementation of a Remote Procedure Call system in Perl.

The Phalanx Project
One ancient Greek military invention was the phalanx, a group of soldiers with overlapping shields each protecting each other. In the Perl world, the Phalanx project intends to improve the quality of Perl 5, Ponie, and the top CPAN modules. Project founder Andy Lester describes the goals and ambitions.

An Introduction to Quality Assurance
The libraries and syntax for automated testing are easy to find. The mindset of quality and testability is harder to adopt. Tom McTighe reviews the basic principles of quality assurance that can make the difference between a "working" application and a high-quality application.

Network Installation of Windows Printers from Samba
The combination of Samba and CUPS makes network printing on a mixed Linux/Windows LAN easier than ever. You can share Linux printers with Windows clients, and Windows printers with Linux clients. A Linux/Samba/CUPS printer server is reliable and reasonably simple to set up and maintain. Carla Schroder, author of Linux Cookbook, shows you how.

Automating PostgreSQL Tasks
Databases aren't just create-once, ignore forever sinkholes for data. You'll likely spend time maintaining them, if not generating reports. Save your tender wrists and automate some of those routine tasks. Manni Wood demonstrates how to combine Perl, the shell, and the psql command-line utility to do repetitive jobs for you.

Introducing mod_parrot
mod_perl marries Perl 5 with the Apache web server. What's the plan for Perl 6? mod_parrot--and it may also be base for any language hosted on the Parrot virtual machine. After a brief hiatus, Jeff Horwitz recently resurrected the mod_parrot progress. Here's the current state, what works, and how to play with it on your own.

The Evolution of ePayment Services at UB
Perl is often a workhorse behind the scenes, content to do its job quietly and without fuss. When the University of New York at Buffalo needed to offer electronic payment services to students, the Department of Computing Services reached for Perl. Jim Brandt describes how Perl (and a little Inline::Java) helped them build just enough code to allow students to pay their bills online.
