Open Inventor is a 3D graphics toolkit for developing interactive graphics applications using OpenGL. Written in C++, Open Inventor is an object-oriented scene graph designed to make the development of graphics applications quicker and easier. Precompiled images for Linux-i386 are available for download.
Open Distributed Data Acquisition System Linux is a mini distribution of GNU/Linux intended for use on the ODDAS project. It contains a shell and some basic commands plus servers for HTTP, FTP and telnet. It also includes the capability to perform syslog over the network, and contains a very simple mail program which allows alerts to be forwarded across the network. The whole thing squeezes into about 3M of flash on an Intel [3-6]86 processor.
The MMX Emulator library provides a simple way to (slowly) execute binaries that use MMX instructions, on processors that do not support them. It can be used if you want to develop MMX code, or execute MMX binaries, on a non-MMX Intel compatible CPU. Please note that well written MMX binaries should contain the equivalent non-MMX code, since the emulation will always be really slow, and MMX code is all about speed.
