PlumpOS is a CD-based mini-openMosix/Linux distribution. Pop the CD into a 586+ computer and you have an instant openMosix node. It supports loading 3rd-party packages and adding custom kernels.

It was originally a clone of Clump/os, but it turned into a complete rewrite. Version 6.9 RC1 was released March 27, 2003. Version 7.0-pre3 was released March 16, 2004.

Majic is the interpreter for a language called Erc. It is written in Java and follows the documented standard for the Erc language. First, a word about Erc: Erc is a link-oriented language. In fact, it is the first link-oriented language. It uses a novel syntax with roots in TCL, Scheme, Bash, and natural languages, among others.

Link orientation is a programming paradigm similar to a cross between link-orientation and object-orientation, with a little hypertext markup thrown in for good measure. In it, although it contains list-like structures which behave like objects, the focus is in fact the links between concepts (structures and elements), as opposed to list organization/processing or object creation.

This makes link-oriented languages such as Erc good for AI or other applications which require keeping track of links between concepts, such as expert systems, semantic searching, and neural nets.

Erc is pronounced URk, with a short U. Majic is pronounced MAH-jik. Both names are derived from the book Web of Angels by John M Ford, in which the Erc was the ethreal currency used in the book universe, and Majic was slang for multiple Erc.

Majic stands for Majic Ate Java Inline Classes, or My Awesome Java Interpreter Code. Erc stands for Enumerate Relative Constants, or Ercs Really Cool. Choose an interpretation, either I sound overconfident (read: like an arrogant jerk), obtrusely technical, or like a hacker with a bad sense of humor. All of that is true, just to clear stuff up.

SpecTcl (pronounced Spectacle) is a powerful nuclear event data analysis too. NSCL SpecTcl project provides an object oriented C++ framework for histogramming and other data analysis operations.

The Tcl/TK scripting language is embedded as the programs command language, providing the user with a powerful, extensible, command set as well as the ability to build custom graphical user interfaces or extend existing ones.

The Xamine display program provides SpecTcl with a powerful visualization component.
