Blackbox is yet another addition to the list of window managers for X. It is written in C++, sharing no common code with any other window manager (even though the graphics implementation is similar to that of WindowMaker). It features small code size, a fast interface with simple menus, multiple workspaces, decorated windows, built-in graphics code to render solids, gradients, and bevels on the fly, and more.
Blackarts is a tool for creating web based documentation repositories from interesting information that shows up in email. It was designed to solve the problem whereby a company or association gathers important documentation in email conversations that never gets recorded in a way that is easily accessible later.

BitGen accepts text strings of 1's, 0's and hex digits and converts them to equivalent "pwl" voltage sources for inclusion in netlists for circuit simulation (with SPICE or Spectre, for example). Periodic waveforms (eg, clocks) can be exported as "pulse" voltage sources. Parameters such as rise time, fall time, pulse width and duty cycle can be set on a waveform-by-waveform basis. BitGen is written in Perl with the Perl/Tk toolkit and has an easy-to-use graphical interface.
