Don't
ask me how I know this because if I told you I'd have to kill you.


This is really intriguing because a Mac store "genius" told me the
same
thing when I asked him how to clean the connectors on Apple's new USB
to
Lightning cable on the end that plugs into the iPhone. The new
connector
is pretty small, maybe 5/16" of an inch across, and pins are tiny.
Now,
I wonder what whoever came up with that idea and you have in common?

It's really nothing new. I used to work on ship board cryptographic
equipment that had to be opened daily. (Ancient Navy). The contacts
would become dirty and/or worn over time. Cleaning them with the
linen/cotton dollar bill was effective and more importantly didn't
scratch or cause any damage to the sensitive contacts. The method
also didn't leave any residue to inhibit the electrical connection.

Maybe the app store guy's granddad was in the Navy. If I see him again,
I'll ask.

Not quite. I am not *that* old (although they had telegraph keys
onboard for emergency communications)

During the time I was in the Navy, messages were sent via teletype
machines transmitted on HF transmitters. Ship to ship and ship to
shore was single channel. The "fleet broadcast" was multiplexed,
multichannel. All was encrypted and deciphered using automatic
cryptographic equipment. This was back in the late 60's and 70's.
Communications via satellite was just being developed and by the time
I left the Navy in 1979, most of the HF transmitter sites were being
de-commissioned.

One of the ships I was on received the first beta "Sat Nav" system ...
a precursor to modern GPS. Very high-tech at the time.
