mnemo memorization tool project is a memory accelerator.
mnemo is an application that helps the user memorize large amounts of arbitrary information and retain it indefinitely.
Items are drilled at progressively longer intervals to allow for new ones.

BoardGame Tool provides a C++ front-end/Python back-end for running board games.
It features an easy and flexible interface to interact with the players and has transparent support for network or AI-controlled games.
Through a clear XML interface, games elements can be specified. Using an easy-to-learn back-end language like Python for rule implementations makes it very easy to implement, adjust, or enhance rules that come with a game.
The same back-end language can be used easily for simple or complex AI implementations.
Main features:
- XML specification with DTD validation for game definition
- Easy-to-learn Python programming for rule implementation
- Integrated and transparent network play
- Network chat with selected players
- Simple interface for programming AI players
- Extensive support for image formats
- Runtime scaling of images, allowing easy application of anything as gamepiece
Games currently implemented:
- Chess
- Go
Enhancements:
- This release includes the data archive with correct licensing information for the Fergus Duniho abstract chess piece set.

Cimon is Perl program wich monitors the load (memory and CPU) on Cisco routers using SNMP, and generates graphics with statistics using rrdtool. Its good for information about your routers health.

It monitors and displays the cpu 5 minutes utilization in percents and free+used Processor memory. The I/O memory(usualy 2 MB) or Fast on high end routers is being monitored too, but there isnt graphic for it. Cimon is good source for information about your routers health. From version 0.2 cimon can do ip accounting using the cisco ip accounting feature.
The logfiles that it generates as the rrd files needed for the graphics are fully compatible with those produced by sasacct (SASs accounting statistics). So you can use its cgi interface also its posibility to generate graphics on demand or on a user defined interval (via crontab and -g option).

IP and Ethernet testing Tool is also known as "IET" and its an ethernet bridge addon for testing of network appliances and applications.
Initialy IskraTel extended and customized the NistNet tool.
However NistNet functions on IP layer and requires that tested equipment be configured to use different subnets and gateways.
Nistnet main purpose was internet emulation while IET main purpose is testing of communication equipment.
Main features:
- no need to reconfigure equipment, just insert a PC with two NICs "on the cable"
- works on the ethernet level with a bridge
- network error conditions:
- packet loss
- delay
- in transmission errors (IP, UDP layer)
- bandwidth restraints
- kernel driver for low-CPU overhead packet processing
- control application for configuring driver engine
- GUI
- CLI
- saving configuration to a text file
Enhancements:
- Fixed support for matching ethernet packets based on the protocol
- Added additional matches for ICMP, TCP and UDP protocols (ICMP Type, TCP/UDP src port and dst port)
- Added target for corruption of IP and UDP packets with optional checksum update.
- Numerous small bug-fixes and enhancements
- IET has entered feature-freez and until version 1.0.0 is released there will be only bugfixes

Swing XML Authoring Tool is a Swing-based authoring tool for the quick and easy development of GUI Java applications.
It implements out-of-box a true MVC framework and uses XML to define the view (SwiXml is used as the XUL engine), BeanShell as a scripting language for the controller, and JXPath as the binding mechanism between the view and model.
Swing XML Authoring Tool provides a complete environment in which it is possible to almost write an entire Java Swing application without writing Java compiled code. The use of XPath makes it very simple to traverse the object tree of the applications business model.
It takes a lot of work to develop a Swing application, laying out and configuring GUI components, and then integrating them with the application functionality. SwiXAT addresses both of these issues by providing a framework based on a complete implementation of the MVC architectural pattern.
The benefits obtained by a such framework are the followings:
- Architectural Correctness: By adopting a true MVC (Model View Controller) based framework, it is very easy to correctly implement any UI application. Its not difficult to write a Java/Swing application, but whats very difficult is to build a good, well designed Swing application, where the adoption of the MVC paradigm permits to reduce the maintenance costs, thanks to the clean separation between the view and the application logic.
- Development Speed: The adoption of a framework reduces the development cost by providing out-of-box, well integrated and easy to use common features, like wizards, plugins, support for MDI interfaces, etc. Moreover, the use of XML to define the user interface, as well as the adoption of an interpreted scripting language, permits to implement the Code&Test development style, where the compilation time is reduced to zero.
- Code Reuse: The net separation between the view and the control logic permits to write reusable modules that can be combined in several manners. The developer is naturally induced to modularize the application and write reusable code, minimizing the effort of building new applications or adding new functionality to existing ones.
SwiXAT is all the above, and we hope youll appreciate our effort.

graph-tool project is a program to help with statistical analysis of graphs.
Main features:
- support for directed and undirected graphs
- support for arbitrary vertex or edge properties
- generic filtering of edges and vertices
- several statistical measurements:
- degree (or scalar property) histogram
- vertex-vertex degree (or scalar property) correlation
- average nearest neighbours degree (or scalar property)
- vertex-edge-vertex correlation
- clustering coefficients
- assortativity coefficient
- average distance
- component statistics
- generation of random graphs with arbitrary degree distribution and degree correlation
- graph history measurement based on filtering
- support for graphml and dot file formats
The core algorithms are written in C++, making use of the Boost Graph Library, and template metaprogramming techniques, with performace in mind. The command line interface and other outlying code are written in python.
