Tcl9 is an umbrella for all projects related to the improvement of the current Tcl language, towards the hypothetical version 9 (current version is 8.5).

Que is a queue-based programming language, very different from other programming languages. Due to the nature of a queue, programs made in Que are automatically parallelized, meaning improved efficiency in multi-core environments.

The Wolfram Machine project is an effort to create a set of documentation and useful modules (both hardware and software) for a computing architecture based on the mathematical theories presented in Steven Wolfram's book _A_New_Kind_of_Science_.

TriOS - The Object Oriented Operating System, is the next generation operating system. Fully based on object orientation, it brings unique features to programmers and end users. Basically everything in TriOS is an object, even files and programs! Enjoy!!

Lightweight multi-platform virtual machine for Zeek Execution Enviroment (ZEE). The ZEE provide a system for developing and run applications in a cross-platform environment.

bMARS is a java implementation of Redcode virtual machine MARS - "Memory Array Redcode Simulator"

gasVM is a 32-bit, register-based virtual machine that has been designed to support a game that the author has undertaken for the development of a game for a game Competition, "Gary's Adventure of Science!" It is designed so that it may one day be implemented and hardware, and is designed to be a RISC machine. While this VM is designed for a single game, it is hoped that it will be useful for others who are looking for a virtual machine platform to embed within their software.

Java bytecode to native code compiler striving for small, standalone executables.

The nap scripting language is an object oriented scripting language which brings together the best features of various scripting languages found on different platforms. The nap-script is a C like programming and scripting language with the following characteristics: - compiles into bytecode - it runs in a virtual machine - can be executed standalone or embedded in C/C++ code - has a well defined assembly language - can do runtime compilation - has a syntax very similar to C without pointers ... and it is still under development :) Check out the mercurial repository to get a glimps on the code.

open source platform independent cell-processor emulation software.

ubcc is a just-in-time compiler for various bytecodes. It is designed for use in operating system kernels.

An implementation of the Common Language Specification (ECMA-335) for a wide variety of computer devices
