AUC (Authenticated User Community) is an intranet system designed for use in an educational organization but is also useful in many other settings. It offers the ability for users to have a uniform web-based interface to discussion forums, e-mail (similar to hotmail, etc.), file management, and a searchable user database. Also, "Interactive Classrooms" provide a means for students and teachers to have a web-based extension to their in-class interaction. The system runs from a C-based monolithic CGI script. MySQL is used for database storage. Also, the web-based mail client supports MIME parts/attachments, IMAP, mbox, and multiple mail folders.
jbofihe (or more correctly jbofi'e) is a parser for checking the grammatical correctness of Lojban text. It also provides approximate translations of Lojban into English. (Lojban is a constructed human language with the interesting property that its grammar can be cast into a form that Bison can parse.) The package includes cmafi'e (a smaller version without grammar checking), and a program to aid lujvo (compound word) construction.
QuizComposer is a system for quiz composition/presentation/response-evaluation on the Web in any language. It features many response types to questions (checkbox clicks, number intervals, character patterns/regular expressions, ordered and unordered sets, and subsets), re-presentation of incorrectly answered questions with/without hints, test quizzes for limited groups, and packaging of quizzes and sets of quizzes for transportation and exchange.
quizpool is a system for administering quizzes. The quizzes can be selected from pools of questions, written in "Question Definition Language", according to rules written in "Quiz Definition Language". When a user starts a session, they are presented with a menu of quizzes available. A quiz can then be selected and completed. If the user has not taken that quiz before, the number of chances they are given to take that quiz is randomly generated from the quiz pools for that quiz. This provides an even (or changing) mix of difficult, medium, and easy questions through the various attempts. All output is created from editable HTML template files, which are separate from the program code. This was developed under Apache and Boa.
