Q20: Are Social Security numbers reused after a person dies?
A: No. We do not reassign a Social Security number (SSN) after the number holder's death. Even though we have issued over 415 million SSNs so far, and we assign about 5 and one-half million new numbers a year, the current numbering system will provide us with enough new numbers for several generations into the future with no changes in the numbering system.

The article covered some math that had been performed to determine the true, actual weight of the data that makes up the Internet. Starting with the weight of a single electron (2 x 10^-30 pound), the author broke down the number of electrons required to charge a single capacitor (the charge equaling a âoe1â in binary) in a computerâ(TM)s memory (40,000), assuming a roughly 50 â" 50 split on 1â(TM)s and 0â(TM)s in a typical 50 kilobyte e-mail. The resulting sum can then be used to determine an electron count per message (8 billion), landing us at a weight for a single e-mail of two ten-thousandths of a quadrillionth of an ounce. Now extrapolate that math across the whole of all Internet traffic; all the e-mail, Web pages, music, videos, instant messages and everything else we all contribute to the Internet. Data-wise you arrive at a mind-blowing 40 Petabyte number. However, that 40 Petabytes only equates to a weight of 1.3 x 10^-8 pound. Thatâ(TM)s right ⦠in real-world terms, all that data equals the weight of the smallest possible grain of sand, one measuring only two-thousandths of an inch across.
The unintended consequence of this is that every user on a system is going to get a fixed ipv6 ip and ipv4 traffic would be gradually phased out. Why bother with the administrative burden of issuing an IP address via dhcp and tracking it, when, you could have an ipv6 theoretically assigned to a customer for the life of a device.
You _ARE_ kidding, right?
Maybe you should check out some information about ipv6 before you make more of a fool of yourself.
There is quite a bit of confusion, and it appears that people like you are the ones that are spreading it. How about just a little ipv6 delivery model to end customers?
Do not use ^S outside of ^R though, or it will freeze your terminals output(commands still run even though you do not get any output until the following is done) for which you will need to ^Q to unfreeze.
As for other history tricks that you did not get in to... All great!

here is a simple cheat-sheet for some of the stuff.
Never trust an operating system.
