Yes. it will. the time frame for QC leaving the lab is something from 15 years to 50years. If it doesn't work in the next 50years it means we understand something about quantum mechanics significantly wrong (or we figured QC is useless for some reason).
There are several milestones:
1) implementing single qubits (done in many systems) and high fidelity readout (done on a few systems)
2) high fidelity operations on single qubits (done on some systems)
3) controllable coupling of qubits (done on some systems) witn good on-off ratio (done on a few systems) in a decent architecture (only very few experiments AFAIU) with a demonstration of simple QIP algorithms (done)
4) scalability in the production yield for solid state systems (NOT done, by far not) or in the resource usage for other systems (atom chips are promising)
5) Quantum media conversion between solid state and optics (done) with decent fidelity (far, far away) for using QIP in Quantum communication as local processors
6) Error correcting schemes to lower the threshold for 2) to a doable value for building a scalable computer (that is, a computer which gains computational power when ressources are added): theroretical (done) and experimental (far away)
7) Theoretical understanding of QIP Architecture (not done)
6, which implies 1-4 (and depending on the scheme also 5) have been solved is the criterion for building an arbitrary powerful QC for arbitrary money. The more you exceed the absolute thresholds imposed onto 2) and 4) the more power you will gain by adding resources (it could be 10 or 10000 physical qubits needed for 1 logical qubit). The question is: when will it be economical to build it? I cant answer this, but the first thing where it may pay off is for protein folding simulations. We are looking at replacing a 100MW input power classical computer by a some MW input power quantum computer (condensing helium). We may look at power cost savings of 10 to 100million of dollars per year runtime of the QC. Currently the schemes which are predicted to scale with current HW (on the rather optimistic end, i.e. the best experiments ever done) may require roughly a 100Million - 1billion Dollar investment into Hardware alone per QC (hand waving approximation), obviously unacceptable. However if the price goes down by a facto of 10 to 100 (which could happen in the next 20 years if better material or schemes are found), then it would be economical.
Yes. Exactly. I would be thankful if my employer helps me to settle a problem which is possible to fix but can make a big difference for my performance.
If my Job is to speak, then so it is. There are a lot of things which i am not good in and i dont complain not being hired for them, and if they are part of my Job i am willing to work on my problems.
If you are not good enough to collect the information yourself and construct your own path, then you should neither be given be given nor thrust others opinions.
I use a VPN because i firmly believe that a malicous neighbor on the same cable trunk does not need to know what i am doing or intercept certain connections. I use a VPN because public and free WLANs and Hotels LANs are uncontrolled cesspools. I use a VPN because i dont want every server operator to be able to identify my location to the block-level (and combine it with other techniques to identify me). I use a VPN because i dont trust GSM encryption. I use a VPN because i dont want to be throttled based on IP or content.
If the FBI wants to see the log of my VPN provider, they can. If i would want anonymity i would go to other measures.
intheritance-based polymorphism allows a compiler to assert that a certain method/member exists (even a virtual method) and optimize away the check for it resp. reducde it to a derefrencing operation. Duck typing does not allow this.
I wouldn't say that if the experiment is verified that SRT or GRT has to be kicked out immediately.
I am by no way an expert on this, but why should the vacuum not have a susceptibility depending on the energy range? For GeV energy range this experiment seems to be consistent with the earlier experiments. SN1987A observations happened in another energy range AFAIU (any experts here?).
So it could be that in the limit in which we measured c up to now (low energies), c is not the c appearing in relativity.
If you want to replace JS for the sake of its limitations, then use java or C#. Both are fully grown languages with all mechanisms and tools you would ask for, a huge programmer base, good JIT implementations and an awesome amount of code already written.
That should read: *in the beginning* the optical unit will be expensive beyond imagination. But the mehtod will pay off, so it will be used more often, people will learn how to do it cheaper and developments costs only appear once, so i would think that in 20 years from now it may be a standard method.
But it is being developed. The optical unit will be expensive beyond your imagination (i know somebody working on an optical unit for an EUV system), but that may have been the same 40 years ago for sub-mum mask aligners.
I see it simple. The student invests his personal time into his future and the state should help him doing so. Other form of investing something in the future of the inhabitants of a state are also helped, like tax exemptions etc. Lets say 10000 Students from you state studying will in you universities for 3 years each roughly corresponds to a 1.5 billion dollar investment of their personal lifetime ($50000/year). If they will earn twice as much money the next 30 years, they will get in total a return on the order of 15billion from this investment, and the state which they live may get a even higher amount back from it. So why not to help them to invest this?
and i seriously dont think that moores law will end soon. Bumps in both directions, extending over some time are nothing unusual. New technologies will rise and Metal-Oxide-Semiconductor processes wont be dominating forever.
Ans this is not an unusual thing at all. The scheme is to save cost for patent lawyers. Big companies have such - lets try not to step on each others feet - agreements often. It makes sense. You can see on the mobile market what happens if companies don't have it.
This is how patents work positively. If MS invented something and Casio want to use it, then Casio pays a reasonable fee for it, even if they use a competitors components (in this case software) otherwise.
we dont use linux because its free of cost but because we believe it does a better job in the areas not protected by microsoft patents than microsoft os and believe a little overpaying in these areas is good for our customers.
Many, maybe most, but as soon as you want to do something which requires a little signal processing, you appreciate more computational power than the AVRs provide.
That is an exxageration. This was not about Germany exiting nuclear power (it is clear since a long time ago that there would be never a new nuclear power plant in Germany), but about Siemens deciding that the future prospects are bad and that they don't want to take the risks. It is unclear if even Japan as a very pro-nuclear nation will build many more power plants.
If there is a regulation change due to Fukushima it may very well be that this happens a few years later (when everything is analysed in detail) and you dont want to be stuck in the middle of an big project, where you just allocated the money when you have to put it on hold for a few years to re-certify everything.
If you have no backing from the government for military reasons for nuclear power, this is an financially extremely risky business.
Source IPs are even worse. A simple dump on the monitor port using wireshark will reveal that there are two ip using different mac and windows machines will display a nice warning message that there is another machine claiming their IP.

Well. i disabled facebook in noscript, just in case they miss it somehow that i have no account there.

Ok. i specify: duck typing is bad for performance.
Compatible with your Universities requirements at least. Dont publish it before you hand it in.

Wouldn't shock me too much.
dynamic typing is bad for jit performance.
Any decent jit compiler for any language will step on the patents of others. One way to be exempt at least from oracle lawsuits is to use java.
If you want to replace JS for the sake of its limitations, then use java or C#. Both are fully grown languages with all mechanisms and tools you would ask for, a huge programmer base, good JIT implementations and an awesome amount of code already written.
If you have another agenda, i cant help you.

So does it now affect sslv3 even with TLS1.0 activated? If not, then upgrade firefox. Version 6.0.2 has ssl2 disabled.

ok guys, why not a link to the excellent japanese metrological agency earthquake information in english?
http://www.jma.go.jp/en/quake/00000000091.html
but rather prefer to use them for something meaningful but the weirdly scrolling ad annoying them in some partialy visible background window....
Well, in SCOs case it took some time....
Well in this case, ok.
They need to be fired for three reasons then:
1) torrenting
2) hacking
3) being idiots.
an easy way to select them.
