Properly done interferometry can make it so this telescope array approaches the angular resolution of a telescope that was actually X thousand miles across, but it of course doesn't give it the same light gathering capability (sensitivity). So it won't be able to see anything new, only resolve much better what telescopes could already see. Important, but really only half the benefit of building larger telescopes.

All the computers delivered to our labs have two speaker setups. It would be nice if some of them had satellite speakers, though. Workstations should be able to use all the DVD audio channels. We look at lots of demos on DVD.
So what if you don't need it to check your email, you don't need your mouse either. (I'm sure lots of hardcore *nix geeks still don't believe in mice.)
Why are you so offended by the fact that he uses windows XP? Why do you assume he should bear the burden of fighting what you view as an evil empire? He wants to play a game and maybe he likes that XP is a little easier to manage than Linux.
The minute an editor says something objective you jump on him for not being blindly pro-Linux?
If slashdot loses the few strands of objectivity it has left it will be of no value. They'd do no service to people by presenting propaganda. I'm quite sure the editors realize this, you'd do well to realize it yourself.
a mars mission is by no means 95% fuel unless youre looking at the design present to reagan in the early 80s. We now know we can get all the fuel we need and refine it and store it right on mars.
It mentioned a two ship approach. Presumably the first ship leaves a couple of years earlier and starts filtering oxygen out of the atmosphere and hydrogen out of the ground water/ice and storing it before the manned mission even takes off. Once they know things are looking good they leave and find a fully fueled space ship for their ride back sitting on mars. Its been proposed by Robert Zubrin a thousand times over (though he didnt even assume the hydrogen could be extracted on site, which we now know is possible)
Its not at all unreasonable and its very refreshing to see the Russians having balls where our leaders havent.
We lost several Ranger missions because of steps people took so we wouldn't contaminate the moon. Now we're going to make the already extremely difficult task of getting to Mars harder just so that we don't cross contaminate with a few specs of dust? Well guess what, there's already a huge amount of material that goes between Earth and Mars. Those Mars meteorites? Their interiors never got hot enough to kill bacteria, and tons of it falls on the Earth every year (and conversly tons of Earth material falls onto Mars every year)
Those policies are really only for the introductory courses.
No, they're not. I've personally seen such a policy brought up in a 3000 level class.
Once the students "pass" this test and take later CS courses, most of the projects are collaborative
As you know, Gary, CS1321 / CS1322 are not CS major only courses. They are required by all majors and several other majors respectively. Their goals (and you can check the course catalogue) are not to test your coding abilities, but rather...
"Foundations of computing with an emphasis on the design, construction, and analysis of algorithms."
so this is not the point at which "people have to be judged on their ability to code"
Still, the administration has decided (reasonably so) that the coding done in the homeworks is a major part of your understanding of the course material.
the 2000 level classes are supposed to be the weed out courses the CS majors. (which we could both lament is no longer the fact)
"The intro CS classes here nail you against the wall, the reasoning being that it's better to weed people out who won't be able to handle it in the beginning rather then let them into the concentration and see them fall apart sophomore or junior year"
Umm... except that the intro class is required by ALL majors, and the second by a huge chunk of majors that aren't CS (IE, EE, CompE). They're not weed out courses by a long shot. That is reserved for the 2000 level CS classes, which can certainly weed you out when you realize you've been a CS major for 2 years and never instructed by someone with a PhD. (that's quite possible, wasn't the case for me, though)
The intro class in question (of which I was a student its first semester, Fall of 99) was certainly the best CS class I took before being able to take the senior level specialization courses. (courses taught by real professors who do real research in their fields)
Very few Gatech CS majors make it to their senior year, though.
Amazing. I seriously didn't think any politician could have a clue about the technical implications of something like this. Well, at least someone on his staff. We need to make this person more popular:)
Similar situation is like the warnings on bleach. Don't drink bleach. So by drinking it you can't sue the bleach company even if you wanted your insides sparkling clean.
Umm... if bleach were originally manufactured to make your insides sparkly clean and 95% of it manufactured today still did, then your analogy would be valid.
I can't put a warning label on a landmine and sell it as a welcome mat without expecting some lawsuits.
This is a compact disc. You put them in compact disc players. You could put it in a Sony compact disc player in your Sony computer and instantly have a Sony paperweight. That Sony put a warning label on it does not make this an obvious or logical thing.
Hey, if a moderater could remove the post I'm replying to that would be great. Did you bother to click on the link? It pops up about 20 porn windows and starts playing sounds.
"a) A single nuke in a suitcase is a minor attack. While it might kill hundreds of millions, it won't wipe out the country. "
There is no point on earth where the population density is great enough for a low yeild conventional nuke that fits in a suitcase to kill over 200 million people. that's 80% of the US population!
"Could it be used to analyze text from certain authors (hey, text and art are no different to a computer - treat words as "pixels" and sentences
and structures flow like colors) and mimic their style? Could this one day be used to turn my dull crud into something Fitzgerald or Hemingway
or even Asimov or Heinlein might have written? "
Hmm... well it would be tricky to do that conversion. Text is pretty linear and images are 2d. You could do it, though, I imagine you'd get garbage out of it. I recall some previous work done with Markov Random Chains in a similar way, and it produced some funny results.
"What happens when one feeds a Van Gogh through the Van Gogh filter? Does the resultant image change much?"
There's not a "Van Gogh" Filter, if you're trying to go from a photo to a Van Gogh painting, you need a training photo that has been converted to a training Van Gogh painting. Thing is, Van Gogh didn't photograph his subjects before painting them. So they use a filtered Van Gogh painting and it gets the job done. Now if they put another Van Gogh painting filtered in the same way through the system with the same training images as that web page shows, it should look like a Van Gogh again, though it would defintely change. (less if it were a work from the same period of his work, very dependent on local structure)
"Does the program apply the "filter" differently depending on what type of input it encounters, or is the same method applied to all input?"
I think it uses the same neighborhood kernal for all images.
"Conversely, can the program be used to recognize when a work is of a certain artist?"
not really, there's no higher order cognitive force driving the procedure. Just finding best neigborhoods and secondary neighborhoods.
"Or can it be used to see if an image has already been passed through a certain filter?"
Again, there's no metric for comparing that in this project that I know of. It converts, it doesn't evaluate.
"Are there cases which cause the method to fail or create an undecipherable image? And if so, are these cases unique or do they conincide with a certain type of artistic style? [e.g. Monet -> Van Gogh just won't work right?]"
Yes, things that are global effects do not work since Hertzmann is using only neighborhood comparisons. Things like watercolor could not be done correctly, as it is not entirely local in structure. You couldn't make a cubist painting either.
I'm doing work similar to some of Hertzmann's previous papers (Non-Photo-Realistic rendering for video). Image Analogies is going to be one of the more populas SIGGRAPH papers this year, and it's deserved. There are however limitations to this procedure. I think people here are getting the impression that it's some brilliant art evaluating and painting program when it's anything but. It's a clever (every research slaps self saying why didn't I think of this) method for duplicating local transformations characteristic of a certain image style. Few things in Vision are, however, intelligent or AI based.
