Feeling bored, bump this up for fun.
From a technician:
While working as a consultant in the eighties, I wrote a simple
dBase program for a client. She phone me a few weeks later to say
that it had stopped saving data.
I dropped by her office, and asked her to enter a record while I
watched. She typed the data, then pressed Ctrl-Q. This conversation
ensued:
* Me: "Whoa! Why did you type Control-Q? Control-Q means 'quit
without saving'!"
* Her: "Well, I found that when I type Control-S to save, like you
told me, the little light comes on, and the computer freezes for a
bit. When I type Control-Q instead, the little light never comes
on, and it saves faster."
The "little light" was the hard drive light.
I don't know whether to laugh or cry.
