Genius is an arbitrary precision integer and multiple precision floating point calculator. It includes its own programming language similar in some aspects to C, bc, or Pascal. It can deal with rational numbers and complex numbers. It has matrix support as well. It uses the gmp library so it is very fast for calculations of large numbers. It has a command line and a GNOME interface. The GNOME interface supports plotting functions and 3D surfaces.
For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
ResearchMaster is a tool that you can trust to help with organization, multitasking, and research, both personal and professional. It provides a place to capture your fleeting thoughts and ideas, and it allows you to hit the ground running on projects.

Compendium is a tool to generate encyclopedia-type Web sites (e.g., databases of books, authors, publishers, and literary genres) from content housed in a MySQL database, based on HTML templates. It generates pages with relatively static content and relies on Ruby on Rails for providing a backend to maintain the database. It radically separates content (in the database) from presentation. To facilitate this separation, it allows users to define their own custom tags and provides a simple translation engine to deal with, for example, tables of contents and navigation paths.
Boolean Expression Solver is a commandline utility that generates a truth table for a given Boolean expression. It is written in Java, so it will run on any platform that has the Java runtime environment installed, but the makefile and shell-script included for convenience generally require *nix.
Omnidic is a dictionary/translator for mobile phones.It works on mobile phones compatible with Java (MIDP 1.0 and MIDP 2.0). The program can contain several dictionaries at the same time. It is not necessary to connect to the Internet during use; the dictionaries are saved on the mobile device.
