NfSen is a graphical web based front end for the nfdump netflow tools.
This is a project to develop and build open source energy monitoring, control and analysis tools for energy efficiency and distributed renewable microgeneration. These technologies are at the heart of sustainable energy systems, monitoring and controlling how energy flows between the various parts of the system. These tasks can be achieved using a low cost, modular, open source microcontroller system known as an Arduino, powerful and flexible enough to form the basis of a wide range of systems. PV installation monitors, solar hot water controllers, household energy monitors etc, can be assembled from a selection of modules linked together with an Arduino and configured using simple to use software libraries.
Prey lets you keep track of your phone or laptop at all times, and will help you find it if it ever gets lost or stolen. It's lightweight, open source software, and free for anyone to use.
