VoiceBuntu (formerly Ubunterisk) is an Ubuntu-based live CD that uses Asterisk and VoiceOne to provide VoIP service without any system installation process. VoiceOne is a Web-based GUI for the Asterisk PBX. Ubunterisk can be used as a phone client as well as a PBX server. Ubunterisk can be administered either remotely or by accessing its local GUI. A capser-rw filesystem is used to store the system's data persistently.
ua is a simple command line tool that finds sets of identical files. The name is derived from the Hungarian word ugyanaz, meaning the same. The development of ua was motivated by the disturbingly often recurring event of waiting too long for a shell script using sorts, md5sums, diffs, and the like to finish finding identical files.
Showcase is a Mozilla Firefox plugin that allows tabs and windows to be managed by showing them as thumbnails in a single window, tab, or sidebar. It includes a find bar that will filter the thumbnails and the capability to select the thumbnails in the same way you would select files in your system.
php-stl is a templating implementation similar to Java's JSTL. This is a tag-based template engine with configurable classes to handle various tags. The templates are written in XML, which differs from the JSTL, but provides clean output. Note that php-stl now provides its own template handling, but leaves intact using either PHPSavant (http://phpsavant.com) or Smarty (http://smarty.php.net/) as a compiler. Note also that php-stl is designed for PHP 5, though a PHP 4 implementation wouldn't be difficult.
