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."
