clac (Command Line Advanced Calculator) evaluates mathematical expressions input via command line arguments or from stdin and writes the results to stdout. Unlike other command line calculators, clac has infix (natural order) expression syntax, is quite comfortable with complex numbers, defines a great many functions and constants by default, and allows easy definition of new user functions and constants using Python.
Hoc, the High Order Calculator, is an interpreted language for floating-point calculations. Its most basic use is as a powerful and convenient calculator, interactively evaluating expressions such as 1+2*sin(0.7). But hoc is no ordinary calculator: It also lets you assign values to variables, define your own functions, and use loops, conditionals, and everything else you'd expect in a programming language.
OneStroke is a gesture-based character input program. Because a tablet PC in tablet mode does not have a keyboard, a software replacement is necessary. OneStroke aims to be a more elegant replacement to the bulky on-screen keyboard. Single-stroke gestures drawn on the main window generate X11 keyboard events in the currently focused window as if typed on the keyboard. This program has been succeeded by CellWriter, please see http://risujin.org/cellwriter or http://freshmeat.net/projects/cellwriter for more information.
DataDrafter is a program that allows you to create your own interactive graphics applications with data editing, navigation, search, and reporting features built in. Use it instead of Visio, for example, to create diagrams, maps, and technical drawings that are interactive and fully integrated with your data. Your visualizations become real applications instead of just wallpaper. You can even share your graphics and data as an application on the Web, or on your own intranet.
UPN-Calc is a RPN (Reverse Polish Notation) calculator for mobile devices that support J2ME and MIDP 1.0. It features arbitrary precision unnormalized BCD arithmetic and provides many scientific standard functions, such as sin, cos, tan, arcsin, arccos, arctan, 1/x, sqrt(x), exp(x), ln(x), and y^x.
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.
Glossword is a system to publish dictionaries, glossaries, and encyclopedias. It features an installation wizard, support for multiple languages, visual themes, multi-domain installation, an administrative interface with multi-user support, built-in search and cache engines, the ability to export/import dictionaries in XML format, and W3C-validated code. Glossword is useful for any sort of dictionary-like content, including sites with game cheat codes, online translators, references, and various kinds of CMS solutions.
