Python Web Graph Generator is a threaded Web graph (Power law random graph) generator. It can generate a synthetic Web graph of about one million nodes in a few minutes on a desktop machine. It supports both directed and undirected graphs. It implements a threaded variant of the RMAT algorithm. A little tweak can produce graphs representing social networks or community networks. It can also output connected components in a graph.
BinarySEC is an intelligent Web application firewall designed to suppress malicious traffic on Web sites and applications. Its artificial intelligence engine learns normal traffic and blocks malicious requests with very high accuracy. BinarySEC secures against a wide range of attacks, including cross-site scripting (XSS), SQL injection, command injection, PHP includes, parameter tampering, buffer overflow, directory traversal, attack obfuscation, and more. BinarySEC for Apache includes a graphical installer and a Web-based administration interface.
Electowidget is a PHP library (initially a plugin for MediaWiki) designed to make it possible to conduct Internet polls and elections using many different voting systems, including the Schulze (Condorcet) method, instant runoff voting, approval voting, and even plain old plurality. It also assists in explaining different election methods by providing an easy way of tallying example elections and comparing the results as computed by different elections. The modular design allows for plugging in new election tallying methods, different ballot designs, and different ballot formats.
BinaryParser is a class that serializes and unserializes binary data, making it possible to read and write binary data files for exchange with programs written in languages like C and Pascal. It is currently able to handle signed integers (small 8 bits, short 16 bits, int 32 bits), unsigned integers (byte 8 bits, word 16 bits, dword 32 bits) and floating point (IEEE754 float 32 bits and double 64 bits). The endianess of the binary value representation can be configured.
PhpMathPublisher is a system for publishing Web pages that include mathematical expressions. Webmasters only have to install some fonts as no CGI scripts or LaTeX programs are required. Each formula is transformed into an image and the generated Web pages can be displayed by all browsers. It can be easily used in a CMS, blogs, and forums.
Fract is a Web-based fractal zoomer for the Mandelbrot set. It has no advanced features, for the goal is to keep the code easy to read for someone interested in fractals. The package also includes an offline renderer that you can use to generate high resolution images of your favorite spots. You can also easily play with the color map.
The Virtual Data Center (VDC) is a digital library system "in a box" for numeric data. It provides a complete system for the management, dissemination, exchange, and citation of virtual collections of quantitative data. It provides everything necessary to maintain and disseminate an individual collection of research studies: including facilities for the storage, archiving, cataloging, translation, and dissemination of each collection. On-line analysis is provided, powered by the R Statistical environment.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
