FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
bingo-cards is a program to create number, word/letter, and picture bingo cards. These cards can be used for entertainment in the car, in a classroom (for example, to teach the element symbols for the Periodic Table), or just with your kids. You could also create bingo cards with little pictures of everyday objects, then call the names out in Spanish, French, Italian, or German (or whatever you fancy).
Ccide reads C, C++, BASIC, or bash source code containing embedded decision tables from stdin, expands the tables, copies the remaining statements, and forms a compilable C or C++ source module, executable bash script, or interpretable BASIC program. Erratic side effects are avoided by evaluating all condition expressions at exactly the same time, and by performing all evaluations and actions in the original sequence.
