Just out of curiosity, can someone point me to information that agrees with the parent's assertion that it is illegal to BE passed on the right in the US? Any state will do. I would just like to read the detail of the law considering it does not seem that it would always be the fault of the person being passed. Thanks
I opened up my digital alarm clock and rewired it so that snooze turns the alarm off until tomorrow instead of normal snooze function. I never used snooze anyway and I always forgot to turn the damn thing back on for the next day.
My understanding from reading the book and looking at all of the images he includes is that the number of columns is essentially infinite but for obvious reasons only a finite number of columns can be shown at any one time. In the book you will notice that he will show a zoomed in image of a CA with maybe 25 columns and 25 iterations but the zoomed out version of that CA with 100 iterations is shown with 100 columns. Sometimes he also seems to show just a vertical slice of the real CA in order to demonstrate its properties but I have a pretty strong feeling that the image width was not the same as the simulation width. Make any sense?
I guess I agree as long as the source of the noise you're talking about is due to the fact that you probably can't really create a signal processor that perfectly matches the mathematics of CDMA. You're going to get noise from rounding errors, non-exact integration, etc. Is this what you're talking about?
Interference from transmitters designed correctly is not a fact of life. With code division multiplexing you can have as many simultaneous transmitters as you can generate orthognal codes. They do not need to broadcast in a single direction and receivers do not need to know the transmitter location, only its code. Google CDMA for more info.
This does not account for uncontrolable interference like cosmic background radiation and solar flares but if you can control those you'll probably not be too worried about this issue anyway.
I have seen watches with similar inscriptions before and I have always been under the impression that they were talking about the crystal oscillator not the front glass. Quartz crystal is more prominant I believe, I'm not sure the point of using other crystals for the oscillator but I feel pretty certain that you don't have a watch with the front 'glass' made of saphire. prove me wrong if you can, I'd love to know that such a thing exsists.
... that, and does EVERYONE subscribing to the list oppose microsoft? I'll bet there's a few ms execs on the list:)
in light of recent microsoft poll fixing games would it surprise anyone if some portion of the records in the list were planted there by microsoft as people who will attest to being confused between windows and lindows? considering the fact that it is hard to see many other uses for the list you've got to think they know something about it before even seeing it.
seems to me that if they are claiming use of the pigeonhole principle they are going to be trying something like the following:
1)create some table of bit strings where the size of the string is 100 times larger than the size of the index into the table
2)encode data as indexes into the table
3)transmit indexes
4)decode data with indexes into the table
now how they get the table from the source to the destination is anyones guess but it seems to me that since the top of their flash animation keeps blinking "revolutionary microchip technology" these tables will be built into hardware. i dont think this can really work for a few reasons, but i just wanted to give my first impression of how it all sounded from my point of view.
It is agreed that generating random numbers HAS been the weak point of OTP. But, this being the quantum world it is god rolling the dice. So, seemingly the only way to crack this random 'algorithm' is to get past the uncertainty principal. I dont think you are going to find many knowledgable people in the field who will say thats possible. Maybe you say, "why should we think they know what they're talking about? physical 'law' has been proven wrong many a time." To that I say...nothing since i cant predict the future. But lets just say that it doesnt seem like the randomness of the quantum world is going away any time soon. so unless you are encrypting something that must stay secret for 200 years or more i would say generating OTP via quantum effects will be good enough for now.
is it just me or does anyone else feel that the photo on the page linked to in the story which seems to show a planet in front of a star is a bit deceptive. the first thing i thought when i saw it was that it was the 'photo of first extra solar planet' in question. obviously that isnt the case but it would be nice if that were made a little clearer. although now that i think about it this is probably chrisd's fault since the actual link doesnt seem to imply the exsistance of a photo. how silly of me to believe a/. headline (o:
IANAP but i believe the oscillation of neutrinos refers to the theory that they switch forms as they travel through space. In theory, at night they will travel a different distance to the detector than they will during the day and possibly have changed to a more or less detectable form in the meantime. Though in comparison to the distance already traveled the distance traveled through the earth would seem to be insignificant to the supposed period of oscillation (some small number of oscillations between the sun and earth if i remember correctly). I think they're just going down a long list of theories and crossing off anything that they can.
According to these folk "a moot question is one that is arguable or open to debate" but "a moot point, however debatable, is one that has no practical value"
also, as an adjective, definition 2b is listed as "Of no practical importance; irrelevant". So it seems as if his use is correct though possibly ambiguous.
someone mod all three of us down so i can forget this ever happened.
Doron Zeilberger of Rutgers University, in a paper
co-authored with his computer Shalosh B. Ekhad, established that among the 3n n-digit ternary sequences at least 2n/17 are square free.
Where was this Shalosh B. Ekhad computer when I was writing a thesis last semester??

Some people would disagree with you.

It becomes a little bit easier to intercept when all your traffic has to flow through a few routes FBI style
And to think that all these years I've been under the assumption that bit flipping can be accomplished with a NOT ;-)
