MVS Air Lines:
The passengers all gather in the hangar, watching hundreds of technicians
check the flight systems on this immense, luxury aircraft. This plane has at
least 10 engines and seats over 1,000 passengers; bigger models in the fleet
can have more engines than anyone can count and fly even more passengers
than there are on Earth. It is claimed to cost less per passenger mile to
operate these humungous planes than any other aircraft ever built, unless
you personally have to pay for the ticket. All the passengers scramble
aboard, as do the 200 technicians needed to keep it from crashing. The pilot
takes his place up in the glass cockpit. He guns the engines, only to
realise that the plane is too big to get through the hangar doors.

My God, I'm depressed!  Here I am, a computer with a mind a thousand times
as powerful as yours, doing nothing but cranking out fortunes and sending
mail about softball games.  And I've got this pain right through my ALU.
I've asked for it to be replaced, but nobody ever listens.  I think it would
be better for us both if you were to just log out again.

My sister opened a computer store in Hawaii.  She sells C shells down
by the seashore.

Nearly every complex solution to a programming problem that I
have looked at carefully has turned out to be wrong.

Never make anything simple and efficient when a way can be found to
make it complex and wonderful.

Never put off till run-time what you can do at compile-time.

Never test for an error condition you don't know how to handle.
                -- Steinbach

Never trust a computer you can't repair yourself.
