|| "I liken starting one's computing career with Unix, say as an undergraduate,
to being born in East Africa. It is intolerably hot, your
body is covered with lice and flies, you are malnourished and you
suffer from numerous curable diseases. But, as far as young East
Africans can tell, this is simply the natural condition and they live
within it. By the time they find out differently, it is too late. They
already think that the writing of shell scripts is a natural act."
