CryptBackup is an encrypted backup application for Linux desktop users. It allows even a layperson to backup their home directory (including the desktop) on an encrypted external device with just a few clicks. Even the setup is only to choose the external device (such as an external hard drive) and to set a password.
CoffeeSaint is a Java application that shows the status of Nagios (version 1 up to 3 and the newer XI) on a screen. It can, if there are no errors, display a Webcam feed.

Gastona is an approach for rapid and easy development in less than 1 MB, including sqlite and the complete documentation with samples. It is useful for developing tools and many other applications. The GUI is built through configuration using intuitive layout managers and the communication with widget and the logic using a text generator concept. Emphasis has been put on featured widgets (assisted table and tree) and in high-level commands (scanning files and a text parser for records).
JCrocus is a GUI that allows representing the network topology definition of microwave cavity filters based on the coupling matrix approach as well as simulating and plotting its frequency response. It is a software tool for electromagnetic engineers; it is also a pedagogic instrument for professors and students in electromagnetic engineering to teach and learn the theory behind the microwave cavity filters.
The primary aim of the Gtk+2 panel project is to provide a panel that reuses whatever is available (if it is not overkill) in the obvious way, such as subclassing GtkWidget instead of implementing applets, or by using a GtkBuilder file instead of defining a new format to customize the panel. This approach gives some additional advantages for free: you can use common tools in uncommon ways. Above all, you can use Glade to design your own panel. All the dependencies apart from GTK+ are (and hopefully will be) optional.
