pngquant — lossy PNG compressor

"pngquant is a command-line utility and a library for converting 24/32-bit PNG images to paletted (8-bit) PNGs.

The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency. Generated images are compatible with all modern web browsers, and have better fallback in IE6 than 24-bit PNGs."

Pulp - Juicy software repository management
Pulp - Juicy software repository management

Pulp is a Python application for managing software repositories and their associated content, such as packages, errata, and distributions. It can replicate software repositories from a variety of supported sources, such as http/https, file system, ISO, and RHN, to a local on-site repository. It provides mechanisms for systems to gain access to these repositories, providing centralized software installation. Pulp provides tracking of which systems are using which repositories along with a full system history of installation actions. It uses a fine-grained, roles-based, permission model (RBAC) that provides authentication and authorization for repositories, including integration with external LDAP.

This bundle provides a way to run a series of application related health checks. Health checks in the scope of this bundle go beyond simple actions like performing a ping to a server to see if it's alive. For example a Memcache server can be alive and not displaying any errors in your Nagios but you might not be able to access it from your PHP application. Each health check should then implement some application logic that you want to make sure always works. Another usage can be testing for specific requirements, like availability of PHP extensions.
