Trace.java is a package used by Java programmers, testers, server administrators and others to understand what happened during the execution of a program. It doesn't generate tracing statements automatically; programmers have to add them. Trace messages go into an in-core ring buffer, a disk log, or both. The disk log can be fixed size with backups. What amount of detail gets logged can be controlled at runtime or launch time. The ring buffer and disk log can be controlled separately. Different subsystems of the code can be controlled independently.
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.
