Quarters is a strategy game for two players. Although its rules are relatively simple, it still offers some of the same opportunities for skill as in chess. This program was originally conceived in the summer of 1986 during a study of the mini-max algorithm for chess playing computers, and was thus designed to offer some of the same type of strategies. The game was originally written in BASIC, then ported to Turbo Pascal, then to C, and finally to Java. The Java version is not necessarily object oriented, since it is a crude port from the C version.
ACFTools is a utility for manipulating X-Plane flight simulator aircraft and weapon models without using its Plane Maker. It can decode both Apple and Intel ACF/WPN formats into plain text files with a syntax similar to C, which can be edited and then re-converted into binary data. It is able to extract almost complete 3D models of aircraft (fuselage, floats, tanks, wings, stabs, propellers, engines) and write it in AC3D modeler format. Edited 3D parts can then be merged into plain text and consequently converted into binary ACF files.
php_db2util is a module that extends PHP with mass data movement functions. It supports connecting to a DB2 server, loading data from a client or server with a replace option or insert option, and exporting data from a table to a client. It also allows the runstats utility to be run to recreate indexes.
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).
