Linux was created by Linus Torvalds in 1991 as a hobby project, and quickly caught as the only freely available Unix-like system of that time. Today, it's one of the biggest operating systems, most notably is the Android project which runs on Linux.

The Linux kernel is written mostly in C and is released under the GNU GPL v2 license. It's one of the biggest open source projects to date with 1,500 developers and over 200 companies contributing to the 4.1 version release June 2015 (LWN.net).

##Programming under Linux

Linux is a Unix-like mostly POSIX compliant operating system. The GNU Compiler Suite is the standard compiler. It comes with glibc as the standard C library.
