From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux is pretty common in embedded devices. For example information screens in buses in my city (Kraków) which display stuff like next stops, OSM map, time, etc. run some kind of customized Linux distribution I think, and you can often see bunch of Tuxes along with console output when it boots up.
Sadly, Windows is also common in signage. Why ever.
There was that recent "malware security" update that crashed so so many systems in airports. I saw more than one Blue Screen of Death that day.
