MDK (MIX Development Kit) provides tools for developing and executing, in a MIX virtual machine, MIXAL programs. The MIX is Donald Knuth's mythical computer, described in the first volume of The Art of Computer Programming, which is programmed using MIXAL, the MIX assembly language. MDK includes a MIXAL assembler (mixasm), a MIX virtual machine (mixvm) with a command line interface, a Guile-based virtual machine (mixguile), a GTK+ based GUI (gmixvm), and a mixvm-Emacs interface (mixvm.el). MDK utilities are extensible using Scheme.
The Linux ABI is a patch to the Linux kernel that allows a linux system to run foreign binaries. It was developed as a follow-on to the iBCS/iBCS2 project for the older 2.2 kernel. It supports binaries from SCO OpenServer, SCO OpenDesktop, SCO Unix 3.x, SCO Xenix 386, SCO Xenix 286 (with userspace x286 emulation), SCO UnixWare 7, Caldera OpenUnix 8, SUN Solaris 2, System V Release 3 (SVR3), System V Release 4 (SVR4), Wyse V/386, and ISC Interactive Unix. Only the Intel i386 platform is currently supported
tkscript is a JIT-accelerated C-like scripting language with bindings for OpenGL, SDL, SDL_net, libpng, and zlib. A plugin SDK can be used to dynamically extend the script engine with custom C functions and C++ classes. It can be used to create portable, 3D, OpenGL-accelerated multimedia applications.
