Podius is a flexible content management system that simplifies building of dynamic Web sites by providing clean ways to create, manage, and publish all kinds of complex content. It offers command-line and Web-based interfaces, and features an intuitive object model on top of a file-based or RDBMS-based persistence layer.
DiaNa is a Perl framework designed to process a huge amount of data, performing from very easy to very complex tasks in a very efficient, spreadsheet-like, batch fashion. DiaNa also features an interactive Perl/Tk GUI, layered on the top of several batch shell-scripts. The DiaNa syntax is a very small and orthogonal superset of the underlying Perl syntax, which allows, for example, comfortable addressing of file tokens and profitable use of file formats throughout the data processing.
Perlbal is a Perl-based reverse proxy load balancer and Web server. It processes hundreds of millions of requests a day just for LiveJournal, Vox, and TypePad, and dozens of other "Web 2.0" applications. One of the defining things about Perlbal is that almost everything can be configured or reconfigured on the fly without needing to restart the software.
ADMLogger is a log analyzing engine. Using this core, users could easily build upon it with plugins. With very little Perl programming knowledge, it may become a powerful tool in a System Administrator's toolbox. ADMLogger creates email reports that can be formatted plain text or full HTML, which is up to the plugin designers to support. The main system has an HTML preference, so if your plugin ignores it, so be it. ADMLogger will also remove all filtered entries from the main syslog file into a second file so your other entries are more noticable.
Perl-LZO (aka Compress::LZO) provides Perl bindings for the LZO data compression library. You can access the LZO library from your Perl scripts thereby compressing ordinary Perl strings. LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed.
