KAlarm lets you schedule personal messages to display, audio files to play, commands to execute, or emails to send. Among its options, it allows you to choose the message font and color, recurrence schedule, whether to display an advance reminder, whether to speak the message or play a sound when it is displayed, and whether to cancel the alarm if it can't be triggered on time (e.g. if you are logged out at the time). As well as using the graphical interface to configure alarms, you can use the command line, and there is a D-Bus/DCOP interface for other applications.
Open Administration for Schools (OAfS) is a Web-based school administration package. Open Admin does demographics, attendance, discipline, report cards, and has an online gradebook and parent viewing function. It is designed for elementary, K-12, and high schools. It generates plain HTML and uses LaTeX for PDF generation. It also includes special education and division-wide central office modules (all schools run on the same server with different virtual sites; two sites per school, one for teachers, and one for the office). Parent functions are by separate parent/school site.
