    God summons Bill Clinton, Boris Yeltsin, and Bill Gates to his office and tells them: “I have called you to announce the end of the world: it has been set by me for midnight on December 31, '95. Go and communicate the good news to the world.”

    Yeltsin gathers the Duma and says: “Dear comrades, I have two bad news to give you: the first is that God exists, the second that the end of the world has been set for December 31, 95.”

    Mini Server @ Home

    I the last years I decided to put a stop on my RasperryPI2 and have a mini pc always on.
