Ficl (Forth inspired command language) is an ANS Forth interpreter written in C. Unlike traditional Forths, this interpreter is designed to be embedded into other systems as a command/macro/development prototype language. Ficl provides object extensions that can be used to wrap methods and structures of the host system without altering them.

AccuRev is a fast, powerful, and easy-to-use Software Configuration Management (SCM) tool with integrated issue tracking based on "Streams" that more efficiently manages complex parallel and global development. Streams are a combination and superset of branches and labels that are first class objects instead of being file-by-file attributes. AccuRev records all merges and patches, so you never have to re-merge the same code. It supports file and directory renaming and merging, follows a client/server model, and is transaction-based. It includes an integrated graphical 3-way diff and merge tool. AccuRev provides an Open API (and SDK) to integrate with any third-party development tool (IBM/Rational ClearQuest, Serena TeamTrack, and more out of the box). It also integrates with Eclipse, the MS SCC API (MS Visual Studio), Sun Java Studio, any diff/merge tool with a command line interface, and more.
Yacas is a general purpose, easy to use Computer Algebra System (a CAS is a program that can be used to do symbolic manipulation of mathematical expressions). It is built on top of its own programming language designed for this purpose, in which new algorithms can easily be implemented. In addition, it comes with extensive documentation on the functionality implemented and methods used to implement them.
Xplanet was inspired by Xearth, which renders an image of the earth into the X root window. All of the major planets and most satellites can be drawn, similar to JPL's Solar System Simulator. A number of different map projections are also supported, including azimuthal, Mercator, Mollweide, orthographic, and rectangular.
