RabbitMQ is a complete and highly reliable Enterprise Messaging system. The RabbitMQ client libraries and broker daemon can be used together to create an AMQP network, or used individually to bring the benefits of RabbitMQ to established networks.
Packages/installers are available for all major operating systems and platforms. RabbitMQ can also be deployed as a VMWare/Debian virtual appliance.
Commercial support services are available from Rabbit Technologies, LShift, and CohesiveFT.
Enhancements:
- This release contains several bugfixes and enhancements in the RabbitMQ server, the Java client libraries, and the examples, as well as improvements to the documentation and packaging.

CyberTester is a Web-based application originally designed to allow teachers to create tests/exams/assignments (consisting of single-choice, multiple-choices or keywords-based questions) and assign them to students to conduct online tests. Students can login to take these tests and review their results.
CyberTester project is suitable to be integrated into online-education services or used as a standalone Web application for a school, college or university.
This latest version of CyberTester (CyberTester2) is implemented using Java Enterprise Edition (with EJB 3), running on JBoss as it application server and MySQL as the database. CyberTester relies on JBoss to manage persistence, relationships and security.
Main features:
- Highly configurable hierarchy tree to group tests, e.g. a hierarchy of Department-Class-Subject-Topic .
- Administrator tools to create/manage users/groups and assign tests to users/groups.
- Administrator tools to create/manage single-choice, multiple-choices and keywords-matching questions using a rich text editor.
- Administrator tools to create/manage tests that contain questions. A test may have a time-limit and a time window in which it can be taken.
- Student test-taking functionality that can be presented either one question at a time or multiple questions in a page.
- Student test results that can be optionally suppressed or be viewable once a test is completed.
- Charting of students performance (very rudimentary at this stage).
- Time limits on questions and/or tests.
- Support for images and external links (via rich text editor) in questions and answer choices.
- Anonymous users who can take the same test multiple times.
