GluX is a cross-platform, easy-to-use OpenGL extension loader. It offers a very simple mechanism for loading and using OpenGL extensions. It allows your code to compile under Windows and Linux even if your video card doesn't support the OpenGL extensions used by your program. At run time, gluX will detect if required extensions are present or not.
Howie is an artificial intelligence agent with a natural language interface (a "chatterbot"). It is designed to be simple to install, configure, and extend. The emphasis is less on simulating a human conversation, and more on providing a "virtual assistant" which provides useful services to visitors through a natural, conversational interface.
The Simple Vector Library (SVL) provides vector and matrix classes, as well as a number of functions for performing vector arithmetic with them. Equation-like syntax is supported via class operators. Both generic (arbitrarily-sized), and fixed-size (2, 3, and 4 element) vectors and matrices are supported. The latter are provided for the efficient manipulation of vectors or points in 2D or 3D space, and make heavy use of inlining for frequently-used operations.
Just one question *why?* :) I approve nonetheless!
