Noostr is a content management system aimed squarely at social news networks. Sites like Reddit, Hacker News, and Digg are all social news aggregators, just like your Noostr site will be. People can sign in, submit news stories or ask questions, and everyone can vote for the best ones. Those top stories float to the front page and generate more traffic, more comments, and more votes.
CheckApp will serve as a basis for a free (as in freedom and as in beer) social network, so that anyone will be able to check out and modify the code, or deploy this application in their own server. It will also try to minimize the usage of personal information, so there would be no privacy problems.
Jabylon is extensible Web-based translation management software. It is meant primarily as a tool to help translators and developers manage and create translations for Java applications. It features tight integration into various source code management systems, a feature-rich Web editor, and a REST API to upload or download translations. It can also be used to offer your user community an easy way of contributing translations for new languages or suggest changes to existing translations.
