A human body can exert only less than one half horse power for a duration of few minutes. One horsepower is equal to 641 calories expended in a one hour period. Your body burns about 100 calories for every mile that you run. Accordingly, you'd have to run about 6.5 miles in an hour. Marathoners will do that easily...the rest of us, not so easily.
Updated February 15, 2017. Linux is an open source operating system (OS) for personal computers, servers and many other hardware platforms that is based on the Unix operating system. Linux was originally created by Linus Torvalds as a free alternative operating system to more expensive Unix systems.
The LinuxÂ® kernel is the core of a large and complex operating system, and while it's huge, it is well organized in terms of subsystems and layers.
