The Parse::FixedLength module facilitates the process of breaking a string into its fixed-length components. Sure, it's a glorified (and in some ways more limited) substitute for the perl functions pack and unpack, but it's the author's belief that this module helps in the maintainability of working with fixed length formats as the number of fields in a format grows.

mod_chroot makes running Apache in a secure chroot environment easy. You don't need to create a special directory hierarchy containing /dev, /lib, /etc... mod_chroot allows you to run Apache in a chroot jail with no additional files. The chroot() system call is performed at the end of startup procedure - when all libraries are loaded and log files open.

MySQL PHP to PostgreSQL is a program that takes a php page that uses mysql calls and changes them into PostgreSQL calls. This allows any website (if it converts properly :) that was written in PHP for MySQL to run as a website written to run on PostgreSQL.

LWP::UserAgent is the default module for issuing HTTP requests from Perl. It has a keep_alive setting which by default allows unlimited requests to the same server. Some servers will disconnect you after a limited number of requests (in Apache 2 this is achieved with the MaxKeepAliveRequests directive). This module allows you to limit the maximum number of keep alive requests to a server.

pgLOGd, simply put, is a program that takes web server log entries and sends them to a database. It is called pgLOGd because of the database it was designed to function with, PostgreSQL. It is fast, robust and features fall-back-logging to a text file. It is flexible and typically uses less than 128K of memory.

QtGStreamer is a set of libraries and plugins providing C++ bindings for GStreamer with a Qt4-style API plus some helper classes for integrating GStreamer better in Qt4 applications. Currently, it consists of the following parts: * QtGLib - Library providing C++/Qt bindings for parts of the GLib and GObject APIs, a base on which QtGStreamer is built. * QtGStreamer - Library providing C++/Qt bindings for GStreamer * QtGStreamerUi - Library providing integration with QtGui. Currently, it only provides a video widget that embeds GStreamer's video sinks. In addition, it provides a "qwidgetvideosink" GStreamer element, an video sink element that can draw directly on QWidgets using QPainter.

This module provides a shared memory cache accessed as a tied hash. Shared memory is an area of memory that is available to all processes. It is accessed by choosing a key, the ipc_key argument to tie. Every process that accesses shared memory with the same key gets access to the same region of memory. In some ways it resembles a file system, but it is not hierarchical and it is resident in memory. This makes it harder to use than a filesystem but much faster. The data in shared memory persists until the machine is rebooted or it is explicitly deleted.
