Spherical aberrations affect the resolution of an STEM by limiting the spot size of the focused electron beam. But by using correctors to compensate for these aberrations, Batson et al. were able to reduce this spot size to less than 1 Å. This allowed them to not only to image single atoms of gold deposited onto the surface of a carbon film, but to observe the relative motion of these atoms with subfemtosecond accuracy.
No problem. The caveat is that you have to take pictures at different angles, keeping the camera at the same location. I guess I now understand you were talking about taking pictures at physical different locations _and_ angles. Yes, then it's harder.
One thing to keep in mind when using hugin, is that if you dont keep your camera at the same position when taking different angle shots, objects very close by get distorted. Far away it's not so much of a problem and its quite fool proof. Check out some pictures I took of our new house http://www.its.caltech.edu/~postma/house/index.htm l. The panoramic ones are the first few.
You would not need just the images, but also very accurate positioning data on where the photos were taken.
In theory, perhaps you could extrapolate the positioning information by looking at static objects in the frame, shadows, etc., but I don't think that's anywhere near practical.
It's actually quite practical, I use this program all the time:
You identify the static reference points, and the program is actually quite clever in finding the other corresponding points after you have picked one or two. You do this for all of them, choose your point of reference, done. It even reads the field of view information from the EXIF header of your digital camera.
You're absolutely right! In fact, I have been getting my fix of Dutch tv news and public broadcasting from real streams quite regularly since I moved to the US _4_ years ago. I'm sure it's been around even longer.
Wouldn't there be some kind of limitation on the EULA anyway? I never understood this, so perhaps some legal expert can advise:
1. Most extreme case: writing a letter saying someone is allowed to kill you, doesn't give the killer the right to kill you. They will still get tried, because they are still breaking the law. It is my understanding that the law is more important than any document you write, right? This is why euthanasia is such a hard issue in the USA...
2. Now back to the EULA, where it seems that somehow I can waive my right to expect stuff not to break my computer.
I for one would love to see Rasterman take a look at the OpenOffice code after he's done with Enlightenment 17. Running e17 now and it is 1) the prettiest 2) the fastest DE I have tried.
I can only imagine how nice it would work if he could use the evas framework to render presentations and other screencontent.
He (Gates) predicted that the HD DVD will be "the last physical media format there will ever be." To help make that happen, Gates said he will need a lot more software engineers.
Oh boy, I hope that doesn't come back to haunt him.
I'm sure he'll be crying all the way to the bank;-)
they probably can't call it a DVD, and will be forced to remove the 'dvd' logo. However, that logo is probably so small most consumers won't realize it. Much like the cd+extra protection. But the consumers will probably still refer to it as a "DVD"
At the risk of starting a "is it GNU/Linux" flamewar...
Opensource is hardly Linus' baby, more like RMS. Not discounting Linus: it was of course smart of him to use the opensource concept, and he can surely code me into a corner.
Plus, don't forget: the kernel is not the (only) thing that makes linux great, it's all the tools Apache/Perl/gnome/kde etc that live on top of it.
Let me speak for myself: I am in the market for buying a new car soon. Why I would go with a hybrid has mostly to do with how I see cars will evolve in the future.
1. Even though it may not make fully economic sense _now_, gas prices have got nowhere to go but up.
2. Hybrid gas mileage has nowhere to go but down. Imagine the combustion engine driving a generator only, charging batteries, batteries driving the wheels. So the combustion engine only fires when the batteries need charging. And the engine load is always the same, runs at fixed RPM, so it's going to be much easier to make it run more efficient and cleanly. And I'm guessing drivetrain (combustion->drivetrain->motion) losses are comparable to combustion->electric->motion losses. I think this is how diesel trains work. The combustion engine probably can also be much smaller, because you don't need a 300hp engine if you can spread the power demand over a much longer time. This compensates somewhat for the weight of the batteries.
3. Once this switch is made, it will be much easier to change fuel type. Just swap out the tank/combustion engine/generator, the latter of which will be a small module (see above).
4. Developing a totally new car costs a lot of money. I read somewhere that it costs around 1 bn dollar, (this is why most brands now use common platforms and common engines. The Saab 97 for instance is just a rebranded Subaru) That's quite a lot of dough. Now imagine developing a totally new drivetrain, as Toyota and Honda do. I am willing to foot part of that bill. It is technology that needs development.

Lotus 123 and Netscape called, they want their excuse back

Seriously, the only way I can see MS Office loosing ground is if there's no preinstalled versions on new pcs, no more closed format documents (and don't get me started on their so-called 'open' XML), in other words: vendor lock-in. Plainly: it's not going to happen unless they are forced... but given how the previous lawsuit worked out, that's pretty unlikely.
I had no problem getting my phone unlocked with Cingular. Yes they require that you finish the first term of your contract (1 year), which is reasonable because that's what you signed up for. But after, the phone is free to use on whatever network you choose.
The first and most significant is that you compare *beta* version with *stable* release. I don't know how you compiled OOo2 - I assume you have'nt and used some binary packages - well beta applications are often not optimised. Often beta compiles have left information usefull for debbuging (that is what beta is for) which slows things down.
That is a good point, made earlier. The version I'm running is a precompiled binary in the preview version of Ubuntu Breezy.
he second flaw is that you think that everybody runs old hardware just for the sake of running old hardware. This is flawed. Actually OOo2 is faster on than 1 on moderately decent machine.
I never said "everybody runs old hardware just for the sake of running old hardware".
I was expressing my personal opinion, that I like the fact that I can run modern apps on my 'older hardware', which in fact is a Pentium III 800MHz with 256 Mb of ram.
Hardware is cheap now so really measuring if foo app starts 2 min. or 8 min. on old Pentium 1 box does not make too much sense.
That depends on what you call cheap. Not everybody can afford to buy a new pc every year. Commodity hardware is not really a commodity, you know? Besides, there is the issue of pollution due to all this 'old hardware' being discarded.
It makes more sense to measure how the software performs and what features do you get (work done?) on the hardware it will be run (now your odlish hardware may be way below the norm).
That is a good point. I haven't really seen any new features that I haven't seen in OO1.1 yet. No idea about what the 'must have' extra features in OO2 are.
It may be that OO2 is still compiled with a lot of debug symbols and code in it that slows things down and that a real release will not be. I have no knowledge of this, it's just speculation.

Not so fast, tiger :) Your first observation is correct.
However, you can in fact see single atoms with a TEM. As always, Google is your friend. Check out this article on a scanning TEM

This allowed them to not only to image single atoms of gold deposited onto the surface of a carbon film, but to observe the relative motion of these atoms with subfemtosecond accuracy.
In fact, you should check out this design for a $100 dollar STM. Build it yourself, and watch the atoms on your tabletop. Quite cool http://www.geocities.com/spm_stm/Project.html

Don't be fooled, that's exactly what the robots want us to believe :)
They failed thanks to ossified bureaucracy, not a lack of police powers.
Yes! This is exactly correct. It was incompetence, not lack of means.

Don't forget beagle either. We finally have a good desktop search without checking out the code from CVS.
Of course they are spitting in our face. Remember, this is slashdot, isn't it? :)

I'm using debian unstable (sid) and OOo2 packages from experimental. While I still find loading time a bit slow, it's still faster than OOo 1.1 IMHO.
That's interesting, since I'm using Ubuntu Breezy which I think is based on sid.
That's a good suggestion, I certainly hope so :)
