When I was coming back from my lunch, I heard this on NPR(KJZZ 91.5FM). 
This should be good program to tune to.

1:00 - Tech Tuesday: Linux

China's post office now uses it; so does the US Navy Warfare Command. 
Disney animators are about to start using it. What is "it"? The open 
source operating system known as Linux. Experts and enthusiasts join 
Kojo for a Tech Tuesday update on what's new in the world of Linux.

Cheers!
Sundar
