UsbCryptFormat is a graphical user interface (GUI) for the encryption of USB flash drives or external hard drives. It allows the user to reformat a USB flash drive, an SD card, or an external hard drive with an encrypted filesystem very easily and without the danger of destroying data on an internal hard drive because of incautious handling of device names. So it is usable even for a layperson.
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.
Psensor is a graphical hardware temperature monitor for Linux. It can monitor temperatures of the different hardware sensors (motherboard and CPU using lm-sensors), hard disk drives (hddtemp/libatasmart), and ATI/Nvidia GPUs. The fan can also be monitored (lm-sensors). Psensor is designed to be simple and easy to use.
ClassicMenu Indicator is a notification area applet (application indicator) for the top panel of Ubuntu's Unity desktop environment. It provides a simple way to get a classic GNOME-style application menu for those who prefer this over the Unity dash menu. Like the classic GNOME menu, it includes Wine games and applications if you have those installed.
jPDFFields is a Java library for working with interactive PDF forms in both AcroForm and XFA formats. It allows your application to get and set field values, and can import and export to the FDF, XFDF, and XDP formats. It can also "flatten" fields in a document. (Flattening is the process of merging the fields into the PDF content layer so the information is retained, but as static PDF content.) jPDFFields is built on top of Qoppa's proprietary PDF technology, so it is 100% Java and does not require any third party software or drivers.
