yaktest is a simple C++ unit testing framework. It has its roots in the JUnit testing framework for Java, but is implemented in a much simpler fashion. Additionally, its output is Emacs-compatible, so adding a "test" target in a makefile makes for fairly simple automated unit testing, with failures directed to the offending line number. An example is included in the source and .gz distributables.
World Foundry is a 3D level game engine and asset production pathway with over 170,000 lines of code. It was originaly created as a commercial product, but is now being released under the GPL. The engine was designed from the beginning to be cross platform, and ran on Windows (DirectX, GL), and the Sony Playstation. The production pathway ran on Windows, and extended 3DStudio Max to be our level editor. The engine is currently being ported to Linux (it runs, but needs work), with plans to port the production pathway as well. Developers are wanted to help with this effort.

TUIpeer works with the TUIAWT Java package, and together they provide a TUI (Text User Interface) look and feel for Java 1.0 and 1.1 applications. In addition, it supports multiple instances of java.awt.Toolkit, a prerequisite for a multi-user JVM. TUIAWT works by sending peer commands and receiving user interface events to and from the remote peer program. Communication with the remote peer program takes place over a socket connection.
