Somehow, somewhere along the way, I'm supposed to have matured and become serious about things. And so it is with Linux. It all started out in fun. I know. I've got Linus Torvalds' "Just for Fun" here on my bookshelf. Says so right there on the front cover. Fun. And it was fun. But as with anyone approaching adulthood, Linux was apparently not taking itself seriously enough. If Linux was to conquer the server room, the desktop, the mobile market, the real time processing world, etc, etc, then it had better clean up its act. Add a little polish. Get serious about business. And it did.
