JAgents (A Game theoretic Evolutionary Network Traffic Simulator) is a tool for simulating dynamics of selfish users in traffic networks like the Internet. Classical Game Theory has been extensively used to analyze the Internet. However, this analysis is limited to static properties of such models, e.g., equilibria, the price of anarchy, etc. Methods from Evolutionary Game Theory allow for analysis of dynamical properties. The behavior of agents is simulated by continuous or discrete processes, the best-known of which is the so-called replicator dynamics. JAgents can simulate a variety of these dynamics for arbitrary networks.
PHP Interactive is a Web based interactive shell for PHP. It tries to be the Web equivalent of the interactive shells of languages like Python, Tcl, and Scheme. It allows users to write code in text areas and see the output of the code on the bottom of the page either in raw or HTML form.
XWiki is a WikiWiki clone written in Java that supports many popular features of other Wikis like the Wiki syntax, version control, attachments, security, and searching, but also many advanced features like templates, database and dynamic development using scripting languages (Velocity, Groovy, Ruby, Python, PHP, and more), an extension system and skinability, J2EE scalability, an XML/RPC remote API, statistics, RSS feeds, PDF exporting, WYSIWYG editing, an Office viewer and importer, and a lot more.
ditaa is a small command-line utility that can convert diagrams drawn using ASCII art into proper bitmap graphics. It interprets ASCII art as a series of open and closed shapes, but it also uses special markup syntax to increase the possibilities of shapes and symbols that can be rendered.
links2world Firewall is an iptables script generator for Linux 2.4.x or newer kernels. The configuration file is very human readable and easy to understand and write. It does not matter if you have one, two, three, or twenty network interfaces; it is able to generate stateful iptables rule sets that control the packet flows between all the networks your machine is attached to.
Diskless Remote Boot in Linux (DRBL) provides a diskless or systemless environment for client machines. It works on Debian, Mandriva, Red Hat, Fedora, and SuSE. Unlike LTSP, it uses distributed hardware resources and makes it possible for clients to fully access local hardware. It also includes Clonezilla, a partitioning and disk cloning utility similar to Symantec Ghost.
PHP System Administration Toolkit is a toolkit/framework for the rapid development of system and network administration Web interfaces in PHP. It tries to take as much common work from the developer as possible, and provides object-oriented interfaces to many common services. It aims to make the applications built using it easily customizable, extensible, and maintainable.
