Spring is a lightweight Java/J2EE application framework based on code published in "Expert One-on-One J2EE Design and Development" by Rod Johnson. It includes powerful JavaBeans-based configuration management applying Inversion-of-Control principles, a generic abstraction layer for transaction management allowing for pluggable transaction managers, a JDBC abstraction layer, integration with Hibernate, JDO, Apache OJB, and iBATIS SQL Maps, AOP functionality, and a flexible MVC Web application framework with multiple view technologies. There is also a .NET port available.
ogEditor is a Web-based WYSIWYG HTML editor with a built-in file manager. It features a Tag Selector which lets you view and edit a tag's attributes and internal styles while working in the Design view of an HTML page. Tag Selector displays the entire chain of tags which apply to the current selection or to the cursor position. When any of the tags is selected, its corresponding element will be highlighted in the Design view, and the selected element's attributes and internal styles are also displayed and can be edited in the Property editor window.
When writing anything that needs to communicate with a terminal in some way, it is almost always speaking some dialect of VT100 or ANSI. The libvt 100 library aims solely at parsing a stream of VT100/ANSI data and then letting the host application do the rendering. Many other projects also parse VT100/ANSI data, but their parser is always tangled up with the actual rendering of the data, making reuse in other projects problematic. The hope is that other projects will start using libvt100 and everyone can stop reinventing the wheel with each project.
TCRun is a tool written by software engineers in QA to help in writing, managing, and running automated test cases. The current version is written in C# for use on Windows, though other versions / platforms may be created later as necessary. It tries to make writing automated test cases as simple and painless as possible. It includes support for NUnit exceptions, logging (both test case specific and framwork/runtime), parameterized tests, test case resource files, and a validation framework. It can be used in mono, but is somewhat untested (it's actually built by mono, and it tests itself).
