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.
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.
My cOLLection manager is a text-based database program for your collections. It is a fast and easy to use front end for gdbm or Berkeley DB with a curses interface. Some other databases are supported. The program was originally designed to organize a large music CD collection, but it has no restrictions on the entry of any other large range of items. Its main goal is flexibility.
