libposix is an impementation of the core functionality of all Unix systems. It is a full, cross-platform implementation of the POSIX 2008 standard. It is meant to replace existing implementations of a Unix system's core libraries. It is an exact implementation of POSIX 2008 and nothing else (no extensions, no previous POSIX versions). However, it works well with possible extensions to the core system functionallity (for example, GNU or BSD).
WaveMaker is a RAD development tool for Web and cloud apps, with more than double the monthly downloads of any other RAD tool. Its visual, drag, and drop tools flatten the Java learning curve by 92%, enabling any developer to build enterprise Web applications that deploy to a standard Java platform. The WYSIWYG studio creates standard Java applications with 98% less code, boosting developer productivity and quality without compromising flexibility. Applications are cloud-ready and include built-in support for multi-tenancy and elastic scaling.
RHQ is a management platform for everything from the OS level load and network metrics through common databases to application servers and projects. The system includes support for monitoring and/or managing Apache httpd, Apache Tomcat, JBoss Application Server, PostgreSQL, and other popular open source projects.

Neural Network Framework is a C++ framework to develop, simulate, and analyze arbitrary complex neural networks. The programmer can use the classes provided to create neural networks with arbitrary topology and mixed type of neurons. It's very easy to add customized neurons and layers.
Akelos is an MVC framework for PHP that tries to bring the magic of Ruby on Rails to the PHP world. Akelos based applications can run on most shared hosting service providers since Akelos only requires a standard PHP installation on the server. Akelos is designed to make developers lives simpler by solving complex problems with unusual speed and productivity. Favoring "convention over configuration" leads to the creation of uniform and simpler-to-understand code.
VRaptor 2 is a Web-based MVC and IOC framework based on many frameworks and ideas (Seam, Stripes, Webwork, Hibernate Annotations, etc). It makes full use of Java 5 Annotations. It favors convention over configuration, because configuration in XML/properties/annotations is always easy to make mistakes and repetitive (aka copy and paste in many places). This framework uses a more imperative approach, instead of having many XML files to configure lifecycle and other properties. Most of the settings go inside plain Java objects (POJO), so the team knows exactly what is going on and where.
