Is this correct or not? 
Take any positive integer of two digits or more, reverse the digits, and add to the original number. This is the operation of the reverse-then-add sequence. Now repeat the procedure with the sum so obtained. This procedure quickly produces palindromic numbers for most integers. For example, starting with the number 5280 produces the sequence 5280, 6105, 11121, 23232. The end results of applying the algorithm to 1, 2, 3, ... are 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 11, 33, 44, 55, 66, 77, 88, 99, 121, ... (Sloane's A033865). The value for 89 is especially large, being 8813200023188.
The first few numbers not known to produce palindromes, sometimes known as Lychrel numbers (VanLandingham), are 196, 295, 394, 493, 592, 689, 691, 788, 790, 879, 887, ... (Sloane's A023108).
The numbers obtained by iteratively applying the algorithm to 196, the smallest such number, are 196, 887, 1675, 7436, 13783, ... (Sloane's A006960), and no palindromic member of this sequence is known. The special number 196 therefore lends itself to the name of the reverse-then-add algorithm. In 1990, John Walker computed 2415836 iterations of the algorithm on 196 and obtained a number having 1000000 digits. This was extended in 1995 by Tim Irvin, who obtained a number having 2000000 digits. M. Sofroniou gave an efficient Mathematica implementation that has complexity for steps, requiring approximately 10.6 hours on a 450 MHz Pentium II to compute 250000 iterations. Extrapolating the timing data suggests that approximately 42 days would be needed on this same machine to match Walker's 2415836 iterations.
The rec.puzzles archive incorrectly states that a 3924257-digit nonpalindromic number is obtained after 9480000 iterations. However, the correct resulting number is 3924578 digits long. In fact, no palindromic numbers occur after 613.6 million iterations, at which point the resulting number has more than 254 million digits (VanLandingham).
The number of terms in the iteration sequence required to produce a palindromic number from (i.e., for a palindromic number, if a palindromic number is produced after a single iteration of the 196-algorithm, etc.) for , 2, ... are 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 1, 2, 2, 2, 2, 2, 2, 2, 3, 2, 2, 1, ... (Sloane's A030547). The smallest numbers that require , 1, 2, ... iterations to reach a palindrome are 0, 10, 19, 59, 69, 166, 79, 188, ... (Sloane's A023109).

68 + 86 = 154
So no, it isn't that good if I got one that didn't work on the second try.

do you think we should have juries? or should judges alone decide cases? Singly or en banc?

Never read anything about it before, sorry.
"Code division multiple access (CDMA) is a form of multiplexing and a method of multiple access that divides up a radio channel not by time (as in time division multiple access), nor by frequency (as in frequency-division multiple access), but instead by using different pseudo-random code sequences for each user. CDMA is a form of "spread-spectrum" signaling, since the modulated coded signal has a much higher bandwidth than the data being communicated.
CDMA also refers to digital cellular telephony systems that make use of this multiple access scheme, such as those pioneered by Qualcomm, and W-CDMA by the International Telecommunication Union or ITU.
CDMA has been used in many communications and navigation systems, including the Global Positioning System and in the OmniTRACS satellite system for transportation logistics."
Hmm... interesting, but I'd have to look into it.

Okay, non-legal question.
I was going to cut about 7 or 8 inches off of my hair, which is currently nearing the small of my back in length and looks like this :

I smell wikipedia
lol
I already checked there, not too much help
each handset has its own code for 0's and 1's
code usually consists of a string of 1's and 0's
each handset has a different code
lets say if Handset A wanted to send a 1 to the tower its code could be 100110 (this could be any combination and length, depends on how the system is programmed) if it wanted to send a 0 it would be the opposite 011001.
Handset B is suppose to have a completely different code, but what doesn't make sense to me is that all the signals are added up and the receiver can decipher what each handset is sending by processing errors and majorities.
Teacher referred to it as "magic" that it works out lol
You take voice, sound, and you convert it to 1s and 0s at the handset and send it through the air in a specific range of frequencies. There is an encryption "code" unique to the connection so that the 1s and 0s are sent out in multiple packets that would mean nothing to someone intercepting it unless they knew how to put them together right. The receiving phone(s) do, thanks to the infrastructure that is running the wireless network. Code Division stands for how it takes the signal and divides it up according to a code. Multiple Access means you can carry more than one signal simultaneous in the same frequency because the handsets and infrastructure base stations can keep it all straight. The more data you can pack in one frequency of spectrum the more bang for your buck the operators get. You purchase a range of spectrum and you want to be able to use it to its fullest, meaning get the most voice and data connections possible in it.NickyE3 said:

THat IS an actual picture. The first one is me.samoth said:Hard to tell without seeing an actual picture (not saying you should post one...). I'm metal, so I think everyone looks better with longer hair. I'm not a fan of bangs, but some people can pull it off if they look like Karl Logan. I never really liked layered hair, either.
Down to the small of your back is pretty long, but as long as it's below sholder level, I think it's probably look good. Really long hair can get annoying.

well put
When I work out problems of multiple handsets being added up at the receiver, slight margin of error and basing anything 50% right and above to be the right string of code, everything works out - just can't wrap my head around it. Guess Ill pull out my CWNA Sybex book and read up on it

I don't have many posed pictures of myself. I have several I scanned from back in HS, but they bear no resemblence to my today. I've been meaning to scan some from my last comp and some more recent ones, but can't do that at school. I've never been one to take pictures of myself, so I'm pretty limited to the very few that friends have taken, and ones from my parent's photo albums.

I have some pics of a comp, but I need to scan them sometime at home. They were taken by my parents in the audience.
I never saw any reason to take pictures of myself, except a couple metal photoshops my friends and I did back in the day.

I think it can be taken several ways. My old friends and I were pretty outspoken in anti-christian talk, as we all know that black metal is cool and imitating it's key players makes one cool as well, lol. I can be playful-blasphemous, and I can be professionally critical. It completely depends on the atmosphere and the people involved. I don't talk offensively unless I'm in my hometown with old friends or around similar people that share similar views.
