I've only revealed the tip of the Linux iceberg, but if there is any doubt Linux is everywhere, consider its latest foray into TV game shows, no less. Watson, the supercomputer and contestant on a specially staged three-day "Jeopardy" event handily defeated two of "Jeopardy's" greatest champions. Yes, Watson is Linux.
The post explains where and how we use Linux in our daily life, but though don't know about it. Really nice stuff.
