Anything to prevent a "cyber-9/11". It'd be like 9/11 except instead of planes there'd be data expressed in electrical waves, and instead of massive loss of life there'd be a period of down-time.
"Unweaving the Rainbow" by Dawkins is all about this (The title is based on someone who said that by explaining how rainbows form Newton made them less wonderful)
This is what a typical X-ray diffraction pattern looks like.
You need to get a sample like that from many angles of reflection, and then use Fourier transforms to piece it back together (which is why pictures wouldn't have been very interesting).
Also I noticed some saying "this can't be used on humans" etc. The idea is to use it to map out the internal structure of molecules, not to see people's bones.
e.g. DNA's discovery was based on this technique, and it's used constantly by the pharmaceutical companies to see whether their reactions are giving the chemicals they want.
So improved techniques like these are a big help to medicine.

The picture the media paints just isn't true. UK, Germany, France have all gone from hating us to liking us all under Pres. Bush.
Actually the downloadable MP4 files are often better quality than the FLV displayed in the applet. Sometimes I'll download the file just to try and get better quality.
While it might be a pretty modern front end to usenet it doesn't help the fact that the back end feed is slowly being strangled by spam
Thanks in large part to Google Groups, which many usenet servers block because so much spam comes from there. I've had to use a separate client to get a message fully into Usenet, via my ISP, because Google Groups were blocked.
Too bad, because if you're not a regular Usenet participant Google Groups would be a nice, easy way to access it.
Everyone misspells "cloud", the correct spelling is "internet".. Just because people draw a cloud on diagrams to symbolize the internet doesn't mean we should call it "the cloud".
I don't know how people who know what the internet is and where the name came from can stand it.
(As you can tell by my sig this is a pet annoyance)
Wow, I had never heard of this before, sounds good! I had been using Microsoft's software, which gives me a "Processor error" when I try to boot Ubuntu, perhaps VirtualBox will have better luck.
Sun just get better and better, I'm slowly finding myself using more and more of their software, and most of it is excellent.
This shouldn't really surprise anyone. Beijing has been way too tight-fisted about internet control to suddenly decide that everything is now fair game. I'm actually amazed they allowed as much as they did.
Me too, I think it's good that they're moving in the right direction
The current chip, Leda, has 28 rings, giving 28 qubits, but theyâ(TM)re not all interconnected to each other, only to a number of âneighboursâ(TM). The Cooper pair in the niobium are technically bosons so they all exist in the same quantum state, Rose claims, which gives the entire superconductor quantum properties even without interconnecting every qubit.
From Rose himself; they're not interconnected, but they still have "quantum properties". So every other approach to quantum computing is wasting time, because you don't actually have to interconnect the qubits?
That doesn't seem a little hard to believe from a company trying to get investors which won't open their hardware up to scientists?
I suggest getting your information from somewhere other than Rose's blog.
Dreamhost is shared hosting, not colo. What do you expect?
If your database is performing inefficiently and slowing my site down I'm glad they try to improve things without just taking the whole lot down until you sort it out.
They say it'll be able to do more than "pattern matching" if they get more funding (but until then that's all it can do)
They give their own definition of quantum computing, which is much broader than most would give
They claim they can do "quantum computing" without needing the qubits to be interconnected, which is the main problem all other major research teams are trying to tackle
Big claims, big predictions, few results
Who ever heard of a quantum computer only capable of pattern matching?!
Thanks to scam companies like this more qualification is needed when referring to "quantum computing".
This is only a little better than the quacks who talk about "quantum healing energy"; they're exploiting the vague term "quantum computing" and the small amount of understanding to try and make a quick buck from investors.
/. has gone from an open source zealot site to an Apple zealot site. People still complain about MS using BSD's networking stack (back in Win 3.1), but don't care at all that Apple built OS X from FreeBSD.
Tactics like the FSF's are definitely misguided, but I'm surprised there's no support whatsoever for the FSF's message.
Google the Orion project; space launches with nukes, payloads that could carry the entire ISS up in one go, along with a few spares, large enough to make inter-planetary colonization realistic, and it's not science fiction.
The problem is the fallout from the bombs of course. But if you take that radiation in perspective it does make you wonder if that would be a show-stopper for an important enough mission.
My physics tutor studies ocean algae and I asked him about this, he said that yes they do release the CO2 when they die. You need to supply a constant amount of iron to keep the algae around and the CO2 locked up.
There are suggestions on how to do this too, using long underwater funnels that get mineral rich water from the deep ocean using power provided by waves. Not sure I buy it.

You can't be serious. Uranium (and thorium as well) reserves are pretty limited, even with breeder reactors. If peak oil really hits hard in the next few years and there's a large increase in use of fission for energy, ores will be depleted within decades.
Can you give a source for that? I realize U-235 is limited, but as I understand we have abundant fuel with breeder reactors.
To be honest there's no real reason to think fusion would be cheaper than coal, and nuclear fusion isn't much different to nuclear fission in most practical regards. It would be more like an improved form of nuclear fission than a revolutionary new technology.
Fusion (in the most viable tokamak form) does produce radioactive waste products because of all the neutron flux, but (like lots of forms of fission) the waste isn't dangerous in the long-term. I also haven't seen any real data on how much fusion would cost on a practical level.
So I don't see why fusion should be treated as anything more than a possible improvement to fission in the future; why aren't we going for fission as the technology to free us from the Middle East in the meantime?
That's what the US did last time there was an oil crisis, and it worked out well, but this time our reactors are much better and safer for the experience.
You misspoke. If the world didn't need oil, the ME wouldn't have the money and power to be a threat. 9/11 might just as well happened--bin Laden's excuse is that he didn't like US troops on the Arabian peninsula. However, he cut his teeth against us in Somalia (no oil there) and against the Soviets in Afghanistan (no oil there either).
But now I have no reason to flog myself for the atrocities perpetrated against my society.:-(

Its sad, so many people have gotten used to having unfair advantage, they consider it their birthright. White males tend to be the worst whiners.
