Zadolbator is a simple reminder component for Jabber server. As it is installed on the server side, it can be used by all users of this Jabber server, and does not depend on the client software used. Its main purpose is to remind you about events such as birthdays or holidays, though it can be used also for keeping your everyday reminders about meetings, things to do, etc. It uses the iCalendar format to store events, so some basic understanding of iCalendar is needed to use it. This also simplifies importing existing events if they're in iCalendar format.
Compendium is a tool to generate encyclopedia-type Web sites (e.g., databases of books, authors, publishers, and literary genres) from content housed in a MySQL database, based on HTML templates. It generates pages with relatively static content and relies on Ruby on Rails for providing a backend to maintain the database. It radically separates content (in the database) from presentation. To facilitate this separation, it allows users to define their own custom tags and provides a simple translation engine to deal with, for example, tables of contents and navigation paths.
