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.
MuseScore lets you notate and compose music easily with your keyboard, your mouse, or a MIDI keyboard. You can print beautifully engraved sheet music or export it as PDF or PNG.

MuseScore is often advertised as a cost effective alternative for Sibelius and Finale.

DB Schema Management is a class that can be used to: extract a database schema into a PHP script that defines the schema in an array; apply the extracted script to recreate the database schema; allow the editing of the extracted script to implement changes to the schema; and allow users of the application to create changes to the schema that are separate to the extracted script. It has support for pre- and post-processing scripts. It can require a minimum schema version to apply the update.
MonoDevelop is a GNOME IDE primarily designed for C# and other .NET languages. intelligent code completion attempts to complete type, method, and field names as you're typing. The IDE automatically gets the class information from your source code files and from the libraries referenced in your project. A class viewer allows you to list the classes in your project, their methods, and properties. Your namespaces are also tracked to keep the classes separated. A powerful add-in engine, a modular API, and a complete set of extension points provides a seamless platform upon which to build your own development tools.
