About xwintermutex

I write code and tinker with electronics for a living. I am concerned about privacy, cyber security, evil governments and evil corporations. I know a bit about computer graphics. I restore old timer machines in my spare time.

    What excited me most in that article is the line "The press event also saw Sony announce that long-awaited game The Last Guardian would soon be released."

    Trivia: a Johnny Popper is a John Deere model M. I am currently in the process of restoring one. It is called a popper because of its distinct sound, caused by the non-180 degree a…
