Does anyone have any information as to how close the detector detector
has to be for an positive identification?

AKRON BBS TRIAL DELAYED
The Akron BBS Trial originally scheduled for Monday, January 4,
1993 has was continued--will *not* happen Monday the 4th. A new
trial date was not determined. Mark Lehrer's attorney requested
the continuance and since Summit County Prosecutor Lynn Slaby
assigned a new prosecutor 'due to calendar year rotation' was not
resisted.

The two keys are complementary. What is encrypted with the private key is
decrypted only with the public key; what is encrypted with the public key is
decrypted only with the private key.

Well, when I worked at UPS (last year), I was constantly in contact with
those clipboards, and it would have taken very little for me or anyone
with the huevos to do some tampering. The fact is, yes it would be
quite challenging to get away with a data heist. But if I had no class,
and could be bought, I know I could find a group of 10 guys to pose
as UPS employees, get past the security gates, walk into a sorting hub,
and nab just as much information as we wanted. Not just electronic
clipboards, but all shipping info that gets scanned. This constitutes
all Next-day air and 2nd day air shipping (Customer record, date of delivery,
sorting pedigree, useless as any of this info may seem).
BTW, UPS is not ignoring security risks. They just ignore people
who ask about safety risks. They know what is possible. But they
do throw some __HEAVY__ penalties for anybody who screws with them.
Any employee of UPS knows the word FELONY, and how easy it could be
to have that word stamped across their forehead. People aren't stupid,
and neither is UPS. They don't typically hire anyone without getting
a complete sample of fingerprints, handwriting & print, photo,
etc, etc. including an FBI check or equavelent.
IMO, though, I think they should do something more to ensure the
safety of their electronic data.

regarding "moving" an "800" number from one carrier to another. This is a
VERY special situation that just started.
history: In the OLD days, the first three digits of the 800 number (after
the 800, that is) defined where the call was supposed to wind up. So, for
example, 800-225-xxxx was the Boston area.
(Oh, the fun we used to be able to have with that...)
More or less 15 years ago, ATT modifed their system so that each 800
number dialed was "looked up" in a central system, and "converted" to a
more normal number. This allowed any 800 user anywhere in teh country to
get whatever number they (or ATT) wanted them to have. Lots of other
advantages to this as well, such as time of day routing, call originiation
routing, etc.
Once divestiture took place (i.e, the breakup of ATT), the original
procedure used with 800 numbers was to give certain prefixes to ATT,
others to MCI, Allnet, etc. So, for example, ATT might have the 800-225
exchange, but 800-950- would belong to MCI.
Move a few years forward. The various carriers all complained that they
couldn't swap numbers, which meant that a customer with, say,
1-800-225-9901 was an ATT client, and could NOT switch carriers while
keeping hte same number.
The FCC listened to this, saw that computer technology had (somewhat)
improved(?), and ordered that just about all 800 exchanges be opened to
every carrier. So.... more or less the following now happens when you
"dial" an 800 number.
1) The call is "held" at the local central office, while
2) a query is made to some sort of centralized data base (I have -no- idea
who figures out who runs this, or charges for it).
3( the info as to who owns the number, which lines to push it through,
etc., are relayd back to the CO, and the call is connected.

There is also a product on the market from uniden that
you plug your detector into and when is senses a radar
detector shuts off your radar unit, a Detectors, detector,
detector so to say (Just saw one in truckstops of america
last wednesday for $90.00).
Wonder how long it'll be before chip registration is required

There is a small problem related to Zip+4. After you decide to possibly
give away some privacy by filing an address forwarding order with the
Post Office, you need to fill it out carefully. Do not use the Zip+4
on your old address, or only mail with that Zip+4 will get forwarded to
you. Yup, I did this once.

I used to put only my last name, apartment number, and Zip+4 code on the
return address space on bills. I thought this would be enough since the
Zip+4 code identified a group of 7 apartments. Once I forgot to put stamps
on my mail, and the letters did get returned to me, but via the Dead Letter
Office. My return address info was considered "insufficient" so they opened
each piece to see exactly where it should be returned.

Actually, it depends on just where you live. In my parents' neighborhood
it works out to one ZIP+4 code per half-block.
However, in some locations, individual post-office boxes have their own
ZIP+4 code. For awhile, my mailing address was PO Box 4####, Memphis, TN,
38174-####. Not that that gives anyone any indication where I live.... ;)
And going to the extreme...I currently live at a unique address that is
served by not one, but two ZIP+4 codes -- one for this address, and one
for this block.
Of course, that might be because I live in a church.... ;)

This can also cause them to generate the wrong zipcode
(including the 5-digit part) if there's another street with a
similar (mis)spelling. And I frequently recieve mail with the
right zip+4 but the wrong city, because I live near the boundary
between two cities that have overlapping zipcodes.
