Window Switch is a tool that allows you to move applications between networked computers. The windows appear where you need them, as they were. You no longer need to save and send documents to move them around; simply move the view of the application to the machine where you need it.
Concurrency Kit provides a plethora of concurrency primitives and lock-less and lock-free data structures designed to aid in the design and implementation of high performance scalable concurrent systems. It was designed to minimize dependencies on operating system-specific interfaces, and most of the interface relies only on a strict subset of the standard library and more popular compiler extensions.
Rodent filemanager is a fast, small, and powerful file manager. Its emphasis is on ease of use for the advanced user, not the computer illiterate. Rodent filemanager (a.k.a. xffm >= 4.6.0) is the next step in the evolution of Xffm, now with a threaded design optimized for multicore processors.
