Using Apple’s Aerial Screensavers on Ubuntu After coming across the [Aerial] (https://github.com/JohnCoates/Aerial) screensavers for Mac, and installing them, I decided that I had had enough of the graphics-demos of my Ubuntu Precise system. I hope to provide a simple guide on how to add them to your setup as well.
First, you need to install xscreensaver (for example with aptitude, but your distro should have it):
sudo aptitude install xscreensaver

I’m not very familiar with the aviation jargon (see FAA’s ADS-B FAQ), but ADS-B is a next-gen system where aircraft are equipped with transponders that periodically broadcast their own positions and receive the reports from both other aircraft (direct air-to-air) as well as air-traffic control (ATC) ground transmitters.
There are two separate ADS-B radio bands: the commercial aviation (CA) is at 1090 MHz while the general aviation (GA) is at 978 MHz. If I can be permitted a gross generalization—the former corresponds to big commercial jets and the latter to small private aircraft.
Because ADS-B is designed to democratize airspace situational awareness (in contrast to the older setup, like from films, where a central air-traffic controller is coordinating all these aircraft that can’t see each other), we can buy cheap RF receivers to pick up and decode the messages being broadcast by aircraft and ground towers to get our own picture of the

This bash script offers quick shortcuts to simulate slower network connections. It is useful when you need to simulate a wireless network on a Linux network server, especially when you are using a virtual machine guest on your local machine or in the cloud.
slow 3G # Slow network on default eth0 down to 3G wireless speeds
slow reset # Reset connection for default eth0 to normal
slow vsat --latency=500ms # Simulate satellite internet with a high latency
slow dsl -b 1mbps # Simulate DSL with a slower speed than the default
slow modem-56k -d eth0 # Simulate a 56k modem on the eth1 device. eth0 is unchanged.
