Xgravity is a program for the simulation of 3D gravitational motion of n-bodies. It reads a file with the current state of the bodies, and displays the motion. It features a nice isometric perspective, Red-Green stereographics, and a stereographic perspective which allows you to see the trace in "real" 3D. There is a GTK GUI interface in development, which gives you the ability to perform basic operations with the system, like modifing objects, rotating, eliminating drift, and launching a simulation.
JKFlow is an easy XML configurable report module for FlowScan. It gives network administrators the ability to monitor for specific applications/protocols/services on directions, which are sections of source- and destination subnets, that can be defined within subnets, on exporters or globally. JKGrapher.pl is an additional CGI-script for displaying the RRDTool graphs.
noto, nofrom attributes are ADDED
it's the main improvement in JKFlow 3.1, and they've changed it in "removed"
