Botan : A C++ library of cryptographic algorithms, including AES, DES, SHA-1, RSA, DSA, Diffie-Hellman, and many others

Botan is a C++ library of cryptographic algorithms, including AES, DES, SHA-1, RSA, DSA, Diffie-Hellman, and many others. It also supports SSL/TLS, X.509 certificates and CRLs, and PKCS #10 certificate requests, and has a high level filter/pipe message processing system. The library is easily portable to most systems and compilers, and includes a substantial tutorial and API reference.

UDAV : A cross-platform program for data array visualization based on the MathGL library

UDAV is a cross-platform program for data array visualization based on the MathGL library. It supports a wide spectrum of graphics, simple script language, and visual data handling and editing. It has a windowed interface for data viewing, changing, and plotting. It can execute MGL scripts, set up and rotate graphics, export to bitmap or vector (EPS or SVG) files, draw TeX-like formulas, and so on.

GLE (Graphics Layout Engine) : A graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures, and slides

GLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures, and slides. GLE supports various graph types (including function plots, histograms, bar graphs, scatter plots, contour lines, color maps, and surface plots) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulae in graphs and figures.

RKWard aims to provide an easily extensible, easy to use IDE/GUI for the R project

RKWard aims to provide an easily extensible, easy to use IDE/GUI for the R project. RKWard strives to combine the power of the R language with the (relative) ease of use of commercial statistical packages. While RKWard is far from finished, it is already useful as an IDE interface to the R language.

Social Networks Visualizer (SocNetV) : A flexible and user-friendly tool for the analysis and visualization of Social Networks

Social Networks Visualizer (SocNetV) is a flexible and user-friendly tool for the analysis and visualization of Social Networks. It lets you construct mathematical graphs with a few clicks on a virtual canvas, load networks of various formats (GraphViz, GraphML, Adjacency, Pajek, UCINET, etc), or create a network by crawling all links in a Web page. The application can compute basic network properties, such as density, diameter, and distances (shortest path lengths), as well as more advanced structural statistics, such as node and network centralities (i.e. closeness, betweenness, graph), clustering coefficient, etc.
