If you ever want to have a lot of fun, I recommend that you go off and program
an imbedded system.  The salient characteristic of an imbedded system is that
it cannot be allowed to get into a state from which only direct intervention
will suffice to remove it.  An imbedded system can't permanently trust anything
it hears from the outside world.  It must sniff around, adapt, consider, sniff
around, and adapt again.  I'm not talking about ordinary modular programming
carefulness here.  No.  Programming an imbedded system calls for undiluted
raging maniacal paranoia.  For example, our ethernet front ends need to know
what network number they are on so that they can address and route PUPs
properly.  How do you find out what your network number is?  Easy, you ask a
gateway.  Gateways are required by definition to know their correct network
numbers.  Once you've got your network number, you start using it and before
you can blink you've got it wired into fifteen different sockets spread all
over creation.  Now what happens when the panic-stricken operator realizes he
was running the wrong version of the gateway which was giving out the wrong
network number?  Never supposed to happen.  Tough.  Supposing that your
software discovers that the gateway is now giving out a different network
number than before, what's it supposed to do about it?  This is not discussed
in the protocol document.  Never supposed to happen.  Tough.  I think you
get my drift.

If you have a procedure with 10 parameters, you probably missed some.

If you put tomfoolery into a computer, nothing comes out but tomfoolery.
But this tomfoolery, having passed through a very expensive machine,
is somehow enobled and no-one dare criticise it.

If you teach your children to like computers and to know how to gamble
then they'll always be interested in something and won't come to no real harm.

If you think the system is working, ask someone who's waiting for a prompt.

If you're crossing the nation in a covered wagon, it's better to have four
strong oxen than 100 chickens.  Chickens are OK but we can't make them work
together yet.

Ignorance is bliss.

        BLISS is ignorance.

Imagine if every Thursday your shoes exploded if you tied them the usual
way.  This happens to us all the time with computers, and nobody thinks of
complaining.
                -- Jeff Raskin

Imagine that Cray computer decides to make a personal computer.  It has
a 150 MHz processor, 200 megabytes of RAM, 1500 megabytes of disk
storage, a screen resolution of 4096 x 4096 pixels, relies entirely on
voice recognition for input, fits in your shirt pocket and costs $300.
What's the first question that the computer community asks?

"Is it PC compatible?"

**** IMPORTANT ****  ALL USERS PLEASE NOTE ****

Due to a recent systems overload error your recent disk files have been
erased.  Therefore, in accordance with the UNIX Basic Manual, University of
Washington Geophysics Manual, and Bylaw 9(c), Section XII of the Revised
Federal Communications Act, you are being granted Temporary Disk Space,
valid for three months from this date, subject to the restrictions set forth
in Appendix II of the Federal Communications Handbook (18th edition) as well
as the references mentioned herein.  You may apply for more disk space at any
time.  Disk usage in or above the eighth percentile will secure the removal
of all restrictions and you will immediately receive your permanent disk
space.  Disk usage in the sixth or seventh percentile will not effect the
validity of your temporary disk space, though its expiration date may be
extended for a period of up to three months.  A score in the fifth percentile
or below will result in the withdrawal of your Temporary Disk space.
