distcc is a parallel build system that distributes compilation of C/C++/ObjC code across machines on a network. It can be set up in just a few minutes and makes builds up to ten times faster. It does not require machines to share a filesystem or have the same libraries or header files, and installation does not need superuser privileges.
The Noble Ape Simulation is a collection of a number of autonomous simulation components including a landscape simulation, biological simulation, weather simulation, sentient creature (Noble Ape) simulation, and a simple intelligent-agent scripting language (ApeScript). Noble Ape also contains a social simulation where the Noble Apes can be tracked in terms of social groups and also over many generations to explain social phenomenon to users looking to study this kind of interaction. It has been in development for more than a fifteen years.
mGSTEP is a software development framework designed primarily for use in embedded devices. It implements the core elements of NeXT's OpenStep that evolved into Apple's Cocoa Objective-C class libraries. The drawing API is a partial implementation of Display Postscript in parallel with the newer Core Graphics API. The stable GUI (AppKit) is X11 based. A Linux framebuffer based GUI backend is also included.
