Free black hole singularity software for linux

Created by accident, all who find you would destroy you. Can you escape?
Endgame: Singularity project is a simulation of a true AI. Go from computer to computer, pursued by the entire world. Keep hidden, and you might have a chance.
Originally created for the Pyweek compo, this version features many bugfixes and enhancements over the compo version. Thanks to Phil Bordelon for many of these fixes.
Enhancements:
- Very Easy mode is actually playable.

WhiteBlack Plone Skin provides a white-black skin for Plone.

WhiteBlack is one of Plone skins from Alternative Plone Skins project.

Install

You can install WhiteBlack Plone skin in the same way as other Plone products:

- Download zip. or .gz archive.
- Install as Zope product: extract Plone skin from archive to directory of products and restart Zope server.
- Install in your Plone instance with QuickInstaller (Plone Control Panel -> Add/remove Products)
- Now your Plone site should have the corresponding skin look.

Note: WhiteBlack Plone skin was created with Plone skin dump product.

SINGULAR is a computer algebra system for polynomial computations in commutative algebra, algebraic geometry, and singularity theory.
Its main computational objects are ideals and modules over a large variety of baserings. The baserings are polynomial rings over a field (eg. finite fields, the rationals, floats, algebraic extensions, transcendental extensions), or localizations thereof, or quotient rings with respect to an ideal.
It features fast and general implementations for computing Groebner and standard bases, including Buchbergers algorithm and Moras Tangent Cone algorithm. Its interactive shell and C-like programming language can be extended by libraries written in the SINGULAR programming language.
Main features:
- Main computational objects: ideals/modules over very general polynomial rings over various ground fields.
- Large variety of algorithms implemented in kernel (written in C/C++).
- Many more algorithms implemented as SINGULAR libraries.
- Intuitive, C-like programming language.
- Extensive documentation: Manual (info, ps, and html), Publications.
- Available for most hard- and software platforms: Unix (HP-UX, SunOS, Solaris, Linux, AIX), Windows, Macintosh.
Enhancements:
- This version is mainly a bugfix release, but it also contains some new features.
- Speed was improved for 64-bit architectures.
- The dmod.lib and perron.lib libraries were added.
- center.lib was improved. ncalg.lib was revised.
- New algorithms were added in primdec.lib.
- An improved version of slimgb was incorporated into groebner.
- The module generator (modgen) was improved.
- The build process was improved to build automatically without patches on 64-bit architectures.

libredblack is a library to provide the RedBlack balanced tree searching and sorting algorithm.

The algorithm was taken from the book "Introduction to Algorithms" by Cormen, Leiserson & Rivest. Frankly I never entirely understood it, but it most definately works!

What is the problem with normal binary trees?: A standard binary tree only works well if the original data is provided in a random order (random in terms of the key being sorted on). If however the data is provided in order, then the tree becomes very un-balanced and searches degrade into nothing more than a linked list.

How is the RedBlack tree different?: The RedBlack tree acts in a way to keep the overall tree fairly balanced as new data is loaded in.

How does it work?: The tree is always organised such that it has the following properties:

Every node is either Red or Black.

A leaf node (a dummy empty node at the end of the tree) is always Black.
If a node is Red then its children are Black.

Every path from the root to a leaf contains the same number of Black nodes.
So from 3 & 4 above, we can see that the longest path (alternating Red and Black nodes) is only twice as long as the shortest path (all Black nodes). Thus the tree remains fairly balanced.

Great! How does it maintain those properties?: Ah, well, thats where I get a bit hazy. I know that it does this by adding Red nodes and then rotating the tree elements and changing the colours to sort out times when two Red nodes become parent-child (breaking rule 3).
