The Internet:

You step in the stream,
but the water has moved on.
The page you seek is not here.

The Web site you seek
cannot be located
but endless others exist.

Memory / Files:

Out of memory.
We wish to hold the entire sky,
But we never will.

Forgot to save the file?
It might have been very useful. 
But now it is gone forever.

Operating Systems:

Chaos reigns within.
Reflect, repent, and reboot.
Order shall return.

Windows NT crashed.
I am the Blue Screen of Death.
No one hears your screams.

Terminal error.
The system’s soul has migrated.
Screen, body and mind are all blank.
(Consult your owner’s manual and burn incense in offering.)
 

Stay the patient course.
Of little worth is your ire.
The network is down.
 

The Tao that is seen
is not the true Tao, until
you add fresh toner.
 

Three things are certain:
Death, taxes, and lost data.
Guess which has just occurred.

ABORTED effort:
Close all that you have.
You ask way too much.

First snow, then silence.
This thousand dollar screen
dies so beautifully.

A crash reduces
your expensive computer
to a simple stone.

Yesterday it worked.
Today it is not working.
Computers are like that.
