Robert Scheifler of MIT, considered the chief design architect behind the X Window System, built an exceedingly clean … Read more

Once you install Linux, and once you get through all the quirks and you set up all the configurations, a Linux server will run until the CPU overheats and dies. It would just run non-stop.
