i believe the largest problem with quantum computing is that as you increase the number of bits, you decrease the chance that you can perform a calculation without a random photon disrupting your calculation.
This means that larger calculations are closer to a statistical answer than a true binary answer.
In order to correct these errors many more qbits are needed - 10^7 qbits in the case of factoring a 1000 bit number . At the moment 7 bits is hard, so a 10 million bit computer is a little way off. As the number of qbits needed for error correction is a (roughly) n^2 problem expanding the number of bits used in classical cryptography is a feasible way to defeat quantum computers, although factoring primes is a polynomial problem, (order n^6 or so on a quantum computer w/ error correction and shor's algortithm).
from TFA : "But it is believed to effect almost any encryption program currently on sale as long as the two volumes being compared use the same encryption key whilst being slightly different from one another"
-- OMG !eleventy-one - if you encrypt 2 slightly different things with the same key you can almost recover the pattern of differences between them. The example on the 'site only works because they take a blank image then compare it to a real one, of the same size encrypted with teh same key. The only way this attack would work in real life is if they had the key (unless people have a large habit of saving, and then backing up, large blank images before storing a picture (which has a large blank background) at the same location.
to avoid : a) initialize the "blank" space in any ecrypted volume to random numbers. b) don't store 2 hours worth if pure black video uncompressed at the same location as any data which has large blocks of ones or zeros.
In other words, if you use a block encryption scheme, then change the data in 1 of the blocks, the encryption only changes in that 1 block, and so you can recover the pattern of differences.
The ability of the brain to interpret signals which do not originate from the retina as (roughly) visual signals has been known for a while - http://www.seeingwithsound.com/ is one application which maps visual to audable signals.
"Begin at the beginning; proceed through the middle until you reach the end, then stop." -- or in the case of a Li-ion battery, stop before the end as running them out can ruin them (recharging them after they reach a too low voltage can potentially create a combustable gas, so there is a safty cutout in there to kill most Lion batteries once they get too flat)
As long as the record was 0kg in orbit (via non-goverment means) getting anything there is a "giant leap" -- sputnik 1 was only 83.6 kg, and there are not many people who wouldn't recognise that that was a significant step.
and as a scripting language, not an arbitrary binary one you can (potentially) completly sandbox the apps as part of the design and implementation of the language.
so buy version 1, place it on your shelf to satify the moral values, then use version 2 to satisfy your usibility requirements. <note -- this may not satisfy the legal requirements - you are still aquiring "bad bits">
Twice yesterday i had flash in one of my tabs take down the entire browser -- if firefox had seperate processes for each then it would of saved me a bit of bother.
So, for me, just yesterday uses up half of that "1 hand of problems" that would be fixed with multiple processes.
the most simple way of _guaranteeing_ that the infomation is not recoveralbe is to heat over 1000'c - at that temperature iron stops having a magnetic memory, so the magnetic state it is in when it cools again is unrelated to before.
isn't it more likely that the reverse will happen? - "they" take some content and use it in a way you don't like, and when you try to sue them they can say "well you agreed to it", which at the least very strongly limits their liability.
the "something" which the extra energy is causing them to vent is thermal photons - the energy itself - all it takes to produce thrust is a non-symmetric object (when rotation is taken into account), so that the photonsarn't evenly distributed.
There are several long wave microwave bands in which the atmosphere is practically transparent - about 1m would be a nice wavelength to use if i remember correctly. Because of the ability to build a tuned antenna to just the 1 frequency you don't need that high power densities - direct solar energy is up to 1000w/m2, so if you beam down at 200w/m2 you can easly catch most of that, powering a city of a sqare km, while maintaining a low enough energy density that you could walk through it and not even notice. [[citation needed]]
and what makes you think it is "your" game - what is sold at stores appears to be physical disks (which you own) which contain software (which you have a liscence for, according to the EULA, but which you don't own)
in http://copywrite.org/2008/01/30/pro-ip-act-of-2007-h-r-4279/ (text of the act as of january), the only place seizure of equiment is mentioned is section 321 a.7.A.iv which reads "Protecting intellectual property rights overseas by working with other countries to ensure that such countries provide for the seizure of property used to produce pirated and counterfeit goods;"
IANAL but to me it seems that a)it is not the seizure of equipment receiving pirated goods, its the equipment used for duplication, so its the sender not the receiver which would lose the equipment. b) this section isn't talking about actions by american forces against american people, it is talking about american political encouragement towards overseas countries in order to get them to seize equipment also.
Can someone point out to me where generic seizure of computer equipment in copyright violation cases is mentioned?

shh, "they" don't need any more encouraging

in general no. however, just like for drug trafficing there are specific laws writting for this situation - its called being an acessory to murder.
This is because (currently) we value a human life more than abstract entities such as money or information.

will you manage to obtain orbit? - the thrust of 500 harriers could manage that with a small payload. (assuming 500 computers per building)
"There are 10 people in the world: those who know about number systems with sufficiently large bases."
and what about the other 11?
