Linux is a free and Open Source operating system that started as a small project by Linus Torvalds in 1991. Today it runs everything from embedded systems to nuclear submarines. Linux also powers Wall Street, the London Stock Exchange, the CERN supercollider, and NASA's supercomputers.

The latest Linux kernel version is 5.12.11. Mainline, stable, and longterm releases are for end users. Release candidate or rc kernels are for developers.

Android, which holds 74.6% of the mobile operating system market share worldwide as of July 2020, uses the Linux kernel.

Linux runs 100% of the top 500 supercomputers in the world as of June 2020.

The idea of the Linux brand character being a penguin came from Linus Torvalds. Larry Ewing created it in 1996 after a suggestion from Alan Cox. James Hughes called it Tux.

Linux containers enable one physical server to run many virtual private servers. There's almost zero overhead. This enables higher density virtualization compared to traditional methods. Each VPS has its own admin. It only takes seconds to make a VPS. Scale on the fly. Reduce capital and operational costs by using technology that runs the web today.

Move virtual private servers between networked physical servers without disconnecting VPS users. Upgrade from old to new hardware with ease. Distribute server load by moving a busy VPS to an idle host or a more powerful machine. This is live migration. Enjoy it with Linux containers.
