Better Perl - How to write perl people don't hate you for later.

Idiomatic Perl

The two frameworks fill different needs. Rails might be great for a completely new product, where you can fully take advantage of its "Convention over Configuration" motto as well as its neat integration between M, V, and C.

Catalyst aims to be an extensible framework. Sure, there are recommendations for new projects, such as using DBIx::Class as the ORM, or Template Toolkit for your view, but these aren't written in stone. Each layer is flexible. You can use CPAN modules to build your own models and views. Want world GDP data? Make a model that calls WebService::CIA. Have your own custom database model already? Use it! (SixApart did this with Catalyst their partitioned database system Memcached).

Catalyst is a little rough around the edges for some of the simpler cases that you might use RoR for, such as a plain old CRUD form system, which Rails will nicely generate for you, but for more complex applications Catalyst is not a bad choice.

I love Catalyst.

The $279 Zonbu Notebook is the latest offering from the Open Source computer company—following up on the $99 Zonbu Desktop released earlier this year. The software is the same OS seen on the desktop, updated with a few new features such as real time data syncing. But the question remains: Does Zonbu find the sweet spot between solid performance and an entry level price?

Sometimes you want to specify which class's method to use, such as when the same named method is specified in two different classes. For example, if the function grind is defined in both Espresso and Qava classes, you can specify which class's function to use by using the :: operator. The following calls would use the call in Espresso:

$mess = Espresso::grind("whole","lotta","bags");

Espresso::grind($mess, "whole","lotta","bags");

The following calls would use the grind() function in the Qava class:

$mess = Qava::grind("whole","lotta","bags");

Qava::grind($mess, "whole","lotta","bags");

You might want to call a method based on some action that the program you are writing has already taken. In other words, you want to use the Qava method for a certain condition and the Espresso method for another. In this case, you can use symbolic references to make the call to the required function, as in the following example:

$method = $local ? "Qava::" : "Espresso::";

$cup->{$method}grind(@args);

A new process for jailbreaking and allowing the installation of non-sanctioned third-party applications to the iPhone has debuted. It’s called AppSnapp, and is unique in two respects: it automates the process on iPhones running software/firmware 1.1.1 (previous methods were multi-step), and it can be completed purely using the iPhone; no interaction with a Mac or Windows computer (as with previous methods) is required. The process will jailbreak the iPhone or iPod Touch then push Installer.app to the device, which contains a catalog of native applications that can be installed directly over a WiFi or EDGE connection (see our Applications page for more instruction on Installer.app).

GROUP_CONCAT(expr)

This function returns a string result with the concatenated non-NULL values from a group. It returns NULL if there are no non-NULL values. The full syntax is as follows:
