Tomb is a system to make strong encryption easy for everyday use. A tomb is like a locked folder that can be safely transported and hidden in a filesystem. Its keys can be kept separate; for example, you can keep the tomb on your computer and its key on a USB stick. Tomb is written in code that is easy to review and links shared components: it consists of a shell script and desktop integration apps; it uses standard GNU tools and the cryptographic API of the Linux kernel (dm-crypt) via cryptsetup.
iPDC is a Phasor Data Concentrator that collects data from PMUs and PDC/iPDC that are compliant with the IEEEC37.118 Synchrophasors standard. iPDC does time alignment and combines the received data into frames as per IEEEC37.118 and can send to other iPDCs and applications. It can also archive received data in a MySQL database on the local/remote machine. It includes a PMU Simulator, which is also IEEEC37.118 compliant. A friendly graphical user interface allows a user to add or remove new devices (PMU/iPDC) and send command frames to the devices from which the data is being received.

Xfce Embed Plugin enables the embedding of arbitrary application windows into the Xfce panel. The window is resized into the panel space available, and the associated program can be automatically launched if it is not open. Example uses include embedding an instant messaging buddy list, a mail client's new mail ticker, a simple media application, or a fancy clock or timer. Combining with Xfce's ability to auto-hide panels can make this very convenient.
