true random one time pads are made from random noise (radioactive decay, random thermal noise in electronics,....) that noone else would have access to. The problem is then shipping it over to the destination.
you are talking about psudo-one-time-pads, using a seeded PRNG. The main problem with most PRNG is that they have a small key and once you have watched a small amount of the output (guessed a small amount of the encripted text) you can predict the rest.
I have come across several PRNG that have a relatively simple implementation, but which have a large enough key space and repeat time that any sort of probabilistic attack is not feasible. (see ISAAC : http://www.burtleburtle.net/bob/rand/isaacafa.html) - it has a key space of over 10^2000 (the number of atoms in the universe times the number of milliseconds the universe is likely to be in existence is about 10^100). The only known attack requires access to many megabytes of output from the generator, and means you only need to check the sqrt of the number of keys (10^1000 keys). baring a mathematical breakthrough there is essentially no chance of messages encrypted with ISAAC generated one time pads this side of the heat death of the universe without the key being given to the person doing the decrypting.
the real question is weather slashdot (providing the service of a public news forum) is required to store your information (ip address, and which login this AC was) indefinately, once this passes.
youtube also provides a way to remove infringing material from the website, something which was not able to be done with the napster network, so in some ways the only way to 'remove' items from the napster network was to sue it out of existance
while an ideal encrypted text is incompressible, in reality the entropy is increased by at most the amount of entropy in the program used to decrypt it. if you ignore the the program and the encryption key, then the actual information (entropy) in the encrypted and unencrypted volumes is identical, its just a little harder to convert one into something that is usefull. (actually possibly both, if the information content is a windows install, but that's another discussion)
This is wrong. No one knows how long each day of creation lasted.i believe most biblical scholars lean on the side that the writer of genesis one intended for a meaning of a single revolution of the earth 'day' not an epoc 'day';
http://www.gotquestions.org/Genesis-days.html has a discussion concerning this
No one knows how long Adam and Eve were in the Garden, it could have been 10 years, or even 10 Billion years for all we know. i agree - the bible does not specify how long adam and eve were in the garden however Genesis 5 does specify how old Adam was when Seth was born, how old Seth was when his son Enosh was born and so on down to Abram (post flood, with years totaling about 1200)
so while people argue over what actually happened, i believe that what the bible claims is quite clear.
3 When Adam had lived 130 years, he had a son in his own likeness, in his own image; and he named him Seth. 4 After Seth was born, Adam lived 800 years and had other sons and daughters. 5 Altogether, Adam lived 930 years, and then he died.
So, I guess the answer is, either don't get the internet, sit there with your child while they are using the internet, or give them an extremely small list of sites they can visit via a whitelist.
Or perhaps even take some responsibility in your own kids, giving them a good upbringing so they know whats right and wrong. I'm sure that there are plenty of opportunities for any kid who wants to to do things they shouldn't until they are older, and no parent can watch their kid 24/7. So teach children some of the moral values that seem to be missing from todays society.

"that someone is willing to pay 20% more than you" all you can tell is that someone was willing to pay at least $1 more than you, as you don't actually know the maximum they have bid.
any photons that are lost are either through interception or absorption are simply ignored - the only thing that can be intercepted is stuff that would end up being ignored by the intended recipient.
what QE represents is a means to ensure that 1 and only 1 recipient can get a message, or part of a message. if the intended receiver of the OTP gets the random key, then he knows that no one else has it and that it can be used to securely transmit a message via conventional means
As there is currently no market for 'windows vista security tools', why would it be illegal for Microsoft to release an operating system with a 'preemptive security hole blocker', that just happens to mitigate the need for specialised and separate antivirus software on this new operating system?
Sure, i can see semantic and the other companies becoming a little annoyed at a lack of a market for their products on vista, but i don't think it would be illegal.
besides, people would (probably) still be able to turn it off and run a product from a different vendor (refer to FireFox becoming more popular)

i play eve, and would agree - there is almost no single 'best' set of stuff to get - with a bit of skill anyone with the right fit out can make life difficult for any single other ship - 2 frigates and a cruiser, with less than 3 months total game time can kill battleships with years of game time if you plan what you are going to do, and the three of you have more skill than the battleship.
ach - I also posted about eve above before i saw the parent post.
With regards to the 'failing doesn't count' and the 'in game time=winning potential' problems mentioned above (parent and other posts), one of the games that i play, Eve Online, has a time based learning system, which allows someone like myself, who would only play a few hours a week, to be competitive with people who are highly active.
The 'failing doesn't count' problem is also over come by potentially loosing your entire inventory every time you die - those people who play more often are a bit(10% for exactly the same skills) better, but they have much more to loose (up to 100x as much).
Within Eve online, there is also no 'best' gear - every fit out has a weakness, which can potentially be exploited - ie, everyone has a chance to survive an encounter against most other people
i know that this system is not ideal, but from what I've seen of wow, it works at least as well. The one downside of this approach is the game is more technical, and if you don't bother to learn how to play (your skill, not your in game characters) a couple of deaths in a row would mean a significant amount of work would be needed to get back to where you were.

run the file through something that reads the watermark - put in a protected work and it comes out with 'sold to joe blogs, copyright fooCorp'
you then try to get the put in other, non-protected, works you just get back random garbage. That would be relatively conclusive (in terms of showing that a copyrighted work had been illegally distributed, not that joe blogs was actually responsible)

or rather, sue slashdot (except its not Australian, even though i am). how does this work - who's guilty here?!

don't you know resistance is futile?

because you could expect your program to use 1000 cpu's for a few days, and only notice the mistake when you program didn't stop
well, prehaps the game industry might now realise that there is demand for more in games than the flashy lights that appease the average 12 year old.
