Cactus is a general, modular, parallel environment for solving systems of partial differential equations. The code has been developed over many years by a large international collaboration of numerical relativity and computational science research groups and can be used to provide a portable platform for solving any system of partial differential equations.
Circus Linux! is a clone of the Atari 2600 game "Circus Atari." The object is to move a teeter-totter back and forth across the screen to bounce clowns up into the air. When they reach the top, they pop rows of balloons and then fall back down. If you don't catch one, you lose a clown.
The Nebula Device is a free multiplatform game engine currently running under Linux and Windows. It uses OpenGL and/or Direct3D for rendering and Tcl/Tk for scripting. Living C++ objects can be browsed and manipulated at runtime from the builtin console, or remotedly from a minimal terminal based console app. A powerful channel animation system allows any floating point attribute to be animated, and specialized animator classes allow things like realtime bone animation with weighted vertex skin.
Xbase (formerly known as xdb) is an XBase compatible C++ class library. It provides C and C++ programmers with a cross-platform class and function library for manipulating Xbase type datafiles and indexes. There is support for .DBF and .NDX files (including support for Dbase III and IV memo fields, dates, and record and file locking), and limited support is also supplied for .NTX (clipper index) files. There is also an HTML user interface class which works well with the Apache Web Server.
SuckMT is a multithreaded replacement for suck that uses client NNTP to download news messages from a news server. It automatically balances the download of all news items over several NNTP socket connections, thus actually using a lot more of the available bandwidth. SuckMT includes kill/keep rules that are regular expressions which can optionally be case insensitive. Statistics are kept how often and when a kill/keep rule was matched for the last time. To upload new messages back to the NNTP server you will still need tools from the suck package.
