This article (http://www.nature.com/nsu/030728/030728-13.html) from the summer had the following speculation-
"Until recently, the agency had planned to have the space shuttle return Hubble to Earth for museum display. "No one wants to do that anymore," says Anne Kinney, head of NASA's astronomy and physics division.
In fact, the US astronaut corps opposes "risking human lives for the purpose of disabling great science" representative John Grunsfeld told the meeting. It would support a servicing mission to extend Hubble's life or ensure its safe re-entry, he said. A servicing trip to the telescope costs NASA about US$700 million, much of which maintains planning teams at the Goddard Space Flight Center in Greenbelt, Maryland.
The option of moving the Hubble to a higher storage orbit has also been dropped. Instead, NASA favours attaching a rocket booster to the telescope in 2010 to steer it to burn up over the ocean.
So far, NASA has found no affordable way to attach the rocket and extend the telescope's life without degrading its performance. Defenders argue that the problem can be solved, and that useful observations can still be obtained from the telescope after the booster is attached."
I guess it's just going to drift while. It's in a 600km orbit.
On multiple occasions I failed polygraph tests that kept me from getting an internship. It's pretty annoying to have someone telling you you're lying. You're really quite powerless to do anything but deny it. Then they'll kindly show you the door.
These things have no place. They are not useful for job screening. They are not useful for investigative purposes. They are not reliable enough for any application. Congress was right to refuse to be polygraphed while under investigation- I would certainly refuse any future polygraph. They shouldn't be hypocrital, though. They should strike down polygraph use entirely.
Trusting polygraphs is a threat to our national security. Not only because double agents and such can easily pass them while lying (any well trained person can), but because so many qualified applicants are replaced with less qualified applicants who can satisfy the voodoo magic of a polygraph machine. Personally, I would like the very best working for the CIA, NSA, etc.
Why do they invite a journalist if they don't expect them to publish what they see? I don't see what the big privacy violation here is. She's a journalist. She wrote a very polished first hand account (so polished and diplomatic I wonder if this wasn't a manufactured leak), and it got published. Am I misunderstanding what journalists are supposed to do?

They're not saying they don't want faster processors with higher address spaces, who wouldn't. They're simply saying that the price/performance ratio is likely to be poor, and they have engineered a good solution using cheaper hardware.
Naturally there are many more problems which can not be parallelized and are not so easily engineered away. Google's statement is no great turning point in computing. Faster processors will continue to be in demand as they tend to offer better price/performance ratios, eventually, even for server farm situations.
(most?) TV tuners can't, right, but there would ideally be a way to get the entire signal before the tuner skims off an individual channel. But a 750 megahertz analog signal would still be bandwidth prohibitive in a modern day computer.
Well, it would take proportionately more bandwidth than a single channel. Each channel runs at 6mhz, and the total cable can carry 330, 450, or up to 750 MHZ total.
So even if those were just 1's and 0's coming at 750 MHZ, you simply can't write that fast to your hard drive.
But it's actually some analog stream that you'd have to convert to digital form, and I don't know what type of overhead that involves.
Technically speaking, the trailer was very impressive I thought. You might have to suspend belief for a second to believe the plot, as outlined, but it was very pretty and had some powerful imagery.
I'm pretty sure 6 year graduation rate means in less than or equal to 6 years. In fact a friend of mine who attends Yalee said they basically do everything in their power to get you out of the door in 4 years. That is a statistic used in collage rankings, after all.
And their defense of this retention rate is, of course, that their admissions process is so good they only get extremely smart people capable of performing very well. As a potential employer I sure wouldn't buy that... seeing how easy it is to buy your way into Yale, after all.
I pointed it out to counter the argument that their graduating GPA's were so high because the people who had done poorly had been kicked out. I wanted to show that there were, in fact, very few people leaving these schools and taking their bad grades with them.
Yale's sophomore retention rate is 98%, their 6 year graduation rate is 94%. I had used the sophomore retention rate as the graduation rate, so I was wrong. Either way, those numbers are quite high.
So you're saying there's a wide range of possible GPA's even within the A range? Well that might be fine for distinguishing people within that school, but comparing grades from one school to the other (as I am lamenting) still doesn't work out.
Do schools really give out tenths of A's? The finest gradation I've ever heard of was thirds.
Well, maybe at your school, but not at Georgia Tech. It really pains me to read about students at other schools getting this treatment, because it's ridiculously easy to fail out here. Heck about half my friends have.
Our published 4 year graduation rate is 69 percent, which seems generous. Maybe it's easier outside the CS department. There are definitely a wide range of C's, D's, and F's given all the way up through third year classes in the CS department.
I've TA'd for the intro class, and we definitely fit the bell curve on high C. I've struggled to get C's in some of my 3000 level classes, not because I'm an idiot, but because the classes were actually curved around middle C's (or slightly less, in two cases).
And I end up having to defend my 3.6 GPA because other ridiculous schools won't even give out C's? That's so dishonest it should be criminal. I've just applied to grad school and I've already had people concerned about my GPA. I think every application needs to be stamped with the average GPA and standard deviation from your school, so that you can actually tell what those grades mean. My GPA gives me highest honors at graduation here, but might not be worth any honors at a joke school like Yale with a 99% four year graduation rate where you couldn't buy a failing grade.
UGH! Why don't slashdot stories have the year in their date? So many news sites do this. It's very annoying. Do they think after a year it will be obsolete knowledge?

07. The original shooting scene between Han and Greedo has been restored.
Thank god. The special edition version is just ludicrous. How does the bounty hunter miss!?
what?! you think this plant is going to be wasted on Japan because it's going to generate more power than they can use? Uhh.. no.
You do realize that fusion power isn't dangerous?

Show some class. Show some self-respect. You don't seem to understand how consulting works.

hehe.. "recieved" is not a word either.

Has nobody posted replies? this must be some sort of error.

For reference, Here's a nice chart, with Duke on top (only because they didn't include ivy leagues) http://www2.acs.ncsu.edu/UPA/peers/current/ncsu_pe ers/retengrad.htm

These schools have 98 or 99 percent 4 year graduation rates, so that's not really causing a large bias.

heheh... very nice. All of these comments are bringing tears to my eyes.. :)
If a particular username has bought a particular cd from your site, you can pretty safely assume they own it.
I guess so, since mp3.com got slapped by the RIAA for allowing people to download CD's they had already ordered.
But how useful is a user name? You need an IP address at the very least.
