Computer Breaker project is a network testing tool for services vulnerabilities.

Computer Breaker is a network testing tool that allows networking administrators to test if a computer is vulnerable to malicious attacks.

Using the Nessus scanner, computer-breaker scans the remote host and automatically exploits its vulnerabilities.

Open Computer Vision Library is a collection of algorithms and sample code for various computer vision problems. The library is compatible with IPL (Intel Image Processing Library) and utilizes Intel Integrated Performance Primitives for better performance.

Philosophy

Aid commercial uses of computer vision in human-computer interface, robotics, monitoring, biometrics and security by providing a free and open infrastructure where the distributed efforts of the vision community can be consolidated and performance optimized.

Computer History Graphing Project is a computer family tree.

The Computer History Graphing Project is an attempt to graph every computer standard, every piece of hardware, every OS, and every computer language in one big family tree.

GeoGebra project is a dynamic mathematics software that joins geometry, algebra, and calculus.

Two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa

ATGeogebra provides a simple archetype product to display GeoGebra files.

GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus .

If you have any interest in educational technology, you should take a look at this fine piece of software: http://www.geogebra.org

The basic idea of ATGeogebra is to be able to show Geogebra worksheet files ( .ggb ) within a plone site.

The .ggb files have to be loaded with Geogebras java applet and the product does that for you.

The software jar files are inside the product’s skins directory and all you have to do is to create a "Geogebra Activity" item and upload the .ggb file.

You will find a sample Geogebra worksheet ( .ggb ) inside the product’s samples directory ( same as shown in the screenshot above ).

If you use CMFContentPanels, a special viewlet will be installed.

This is a initial release. Its very simple, but fully functional.

GCompris is an educational software which propose different activities to kids from 2 to 10. Some activities are game oriented, but always educational. You will find some activities in the following topics:
- computer discovery: keyboard, mouse, different mouse gesture, ...
- algebra: table memory, enumeration, double entry table, mirror image, ...
- science: the canal lock, the water cycle, the submarine, ...
- geography: place the country on the map
- games: chess, memory, ...
- reading: reading practice
- other: learn to tell time, puzzle of famous paintings, vector drawing, ...
GCompris project proposes more than 60 activities and it continues to evolves. GCompris is a free software, you have the possibility to adapt it to your needs or to improve it, and, why not, to share your work with the kids of all the world.
GCompris intent is to provide a central location where a user can find different kind of small educational content called boards.
Today there is already a lot of free software that provides a small education content. Unfortunatly, it is difficult to track, intall and use them because they do not evolve at the same speed and offer their own user interface.
GCompris aims to provide a unique user interface that gives access to different boards.
GCompris is part of the GNU project.
Once started, GCompris presents a graphical view that includes from top to bottom:
1. Boards icon list Each icon represent a board. When you move the mouse over them, they are highlighted and the name and description of the board is displayed in the board description area.
2. Boards description area Display a small description of what the highlited board icon is about. Note that the descriptions are internationalized which means translated in a target language (See section Internationalization Issues for more information on Internationalization).
3. Control bar: The control bar is always present in GCompris. This icons are contextual which means that when an icon is not meaningfull in a specific context, it is simply not displayed. The control bar contains the icons from left to right:
1. Help: In some case, a board can be too complex to be described in the Board description area. In this case this will provide access to the additionnal instructions.
2. Level: Some boards provide different level. The number of levels is board dependant.
3. OK: Some boards do not automatically detect that the child has finish the given task. Clicking here is similar to entering RET on the keyboard and thus the RET key is a shortcut.
4. End: End the current board if any, otherwise Exit GCompris. When entered at the board menu level, it will create a dialog window to confirm the Exit of GCompris.
5. About: Display the about box for gcompris with the version number, the author, the licence and links to online resources.
6. Configure: Display the configuration box for gcompris. Configuration can be done at gcompris level when no boards is selected. If a board is selected, it can provides configuration options. Configuration is persistent and saved in the gnome file in the user home directory under .gnome/gcompris.
Whats New in 8.3.3 Stable Release:
- GCompris was asserting when you clicked on the target image in the missingletter activity.
- GCompris was unstable in Spanish and in any locale where there are no spoken congratulation.
- Even if they were present, audio congratulations were not played on Windows.
- All of these problems were fixed.

Open Computer Forensics Architecture (OCFA) is a modular computer forensics framework built by the Dutch National Police Agency. The main goal is to automate the digital forensic process to speed up the investigation and give tactical investigators direct access to the seized data through an easy to use search and browse interface.
The architecture forms an environment where existing forensic tools and libraries can be easily plugged into the architecture and can thus be made part of the recursive extraction of data and metadata from digital evidence.
The Open Computer Forensics Architecture aims to be highly modular, robust, fault tolerant, recursive and scalable in order to be usable in large investigations that spawn numerous terabytes of evidence data and covers hundreds of evidence items.
Enhancements:
- This release fixes a memory leak in the evidence library and adds a workaround to limit the impact of a memory-hungry indexer module.
