pngcheck is the official PNG tester and debugger. Originally designed simply to test the CRCs within a PNG image file (e.g., to check for ASCII rather than binary transfer), it has since been extended to check and optionally print almost all the information about a PNG image and to verify that it conforms to the PNG specification. It also includes partial support for MNG animations.
RabbIt is a mutating, caching Web proxy used to speed up surfing over slow links like modems. It does this by removing advertising and background images and scaling down images to low quality JPEGs. RabbIT is written in Java and should be able to run on any platform. It does depend upon an image converter if image scaling is on. The recommended image converter is "convert" from the ImageMagick package.

Joseki is a server for publishing RDF models on the Web. Models have URLs can be accessed by queries using HTTP GET. As part of the Jena RDF toolkit, it provides a coarse-grained Web API that is based on extracting a subgraph from the published RDF. The extracted RDF can then be processed locally with the fine-grained API provided by Jena. Joseki is extensible - new query languages and new operations can be added without modifying the core system.
Virtual Exim is a PHP-enabled Web interface for managing multiple virtual mail domains with Exim and MySQL/PostgreSQL. POP/IMAP accounts, aliases, forwards, and permanent fail accounts can all be created and managed easily without the need for corresponding shell accounts.

Individual users can also log in to change their "Real Name", passwords, and mail filtering options with ease.

It is able to group regions based on the URL and produces text or comma-separated reports.
