I've been wanting to do screencasts on Linux for some time now, and my big stumbling block has been determining what tools to use.

The tl;dr:

• Use recordMyDesktop to record video clips, but afterwards, re-encode them to AVI (see the script I used)
• Record audio to WAV, or convert compressed audio to WAV format afterwards.
• Use OpenShot to stitch clips together and layer audio and video tracks.
• Remember to reset the video length if you change the playback rate.
• Export to a Web + Vimeo profile for best results.

One of the exciting features of the newly released Zend Framework 2 is the new module system.

While ZF1 had modules, they were difficult to manage. All resources for all modules were initialized on each request, and bootstrapping modules was an onerous task. Due to the difficulties, modules were never truly "plug-and-play", and thus no ecosystem ever evolved for sharing modules.

In Zend Framework 2, we've architected the MVC from the ground up to make modular applications as easy as possible. Within ZF2, the MVC simply cares about events and services — and controllers are simply one kind of service. As such, modules are primarily about telling the MVC about services and wiring event listeners.

To give you an example, in this tutorial, I'll show you how to install the Zend Framework 2 skeleton application, and we'll then install a module and see how easy it is to add it to the application and then configure it.
