Linux Computers

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.

        n = ((n >>  1) & 0x55555555) | ((n <<  1) & 0xaaaaaaaa);
        n = ((n >>  2) & 0x33333333) | ((n <<  2) & 0xcccccccc);
        n = ((n >>  4) & 0x0f0f0f0f) | ((n <<  4) & 0xf0f0f0f0);
        n = ((n >>  8) & 0x00ff00ff) | ((n <<  8) & 0xff00ff00);
        n = ((n >> 16) & 0x0000ffff) | ((n << 16) & 0xffff0000);

                -- C code which reverses the bits in a word.

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

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.
                -- D. Gries

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

Never trust a computer you can't repair yourself.

Never trust an operating system.

Never try to explain computers to a layman.  It's easier to explain
sex to a virgin.
        -- Robert Heinlein

(Note, however, that virgins tend to know a lot about computers.)
