A better analogy would be to continuously move a circle on the surface until it becomes a point. In the case of a donut, you could draw the circle through the middle hole and around again, so you can't "shrink it to a point" my continuously moving it anywhere; it goes around the donut anywhere you put it. With a sphere, though, you can continuously move the circle to a "pole," where it becomes a point. This property is called simple connectivity.
It's pretty easy to see that all simply connected 2-manifolds (in 3 dimensions, at least) are homeomorphic to the shell of a sphere, i.e. they may be stretched and contorted to look like it. The question answered here is whether the same is true in the next dimension.
I do! I'm paranoid about my important and expensive CDs becoming scratched, so I rip ISOs and store them on my hard drive. So even if I lose the driver CD for my laptop, I can burn a new one in thirty seconds to use.
Recall that the decibel is a (logarithmic) measure of sound intensity, and that is subject to the inverse square law. If one halves the distance between the source and the observer, the intensity is doubled. The decibel measurement is not doubled, since the scale is logarithmic, but it is still clear that, as the source comes closer to the observer, the decibel measurement becomes very large.
Also, as another poster noted, the ear is more sensitive to some frequencies than others; therefore, a table like this is a bit too simplistic.
Ok, and she is doing all this while reformatting her Windows box, and replacing it with the latest Linux distro ? or... What is this doing on Slashdot ?:P
This is the perfect opportunity to compile Gentoo!
I use Linux mostly because I have more fun with it than I do with Microsoft operating systems. I could wax philosophical about free software, or berate their evil empire... But I just do it because I like it.
I'm all for proving the 3n+1 conjecture... Every few months, I get an idea, work at it, and conclude that it doesn't help. Unfortunately, it was shown (by Conway, I think) that similar statements are unprovable. That kind of thing just ruins my day.
If anyone hasn't heard of the problem, pick any integer greater than zero. If it is even, divide by two. If it is odd, multiply by 3 and add 1. Repeat this. The conjecture is that eventually you will get back to one.
It's interesting that the neckties were the cause for concern, but not the shirts or the belts. I'm assuming that's because the neckties are not washed as regularly as another other item of clothing.
It might also have to do with the fact that a tie may dangle, and therefore may have more contact with or get closer to patients than a shirt would. Tie tacks to the rescue?
Well, any application you write can interface with spelling programs to do it... Gaim has done it for a long time. Or you could just use the utility in KDE or Gnome that looks up words for you. Or you could keep a dictionary by your desk. Or you could use Google. Or...
You're not strange, but different people are... Well, different. It depends on how you use your system. For instance, if you use them mostly for work, don't do many upgrades, or have no fun in life, then you won't have to do many reinstalls. If you use your system for recreation, sometimes it's just easier to reinstall everything than to go through and clean out everything that you've installed over the past months, like that guitar tuning program or Real Player (bleh). Back when I didn't have internet, I would reinstall very often because all my data was on a separate hard drive and I didn't have to download 45 updates to ensure that my computer wouldn't be cracked. NOTHING beats the silky smooth feeling of a freshly installed OS.
AND it has a USB port, so you don't have to get your hands on a TI serial cable. I thought that was nice.
I went to the AMS meeting in Phoenix this year, and a few weeks before I received a flyer from TI in the mail: "EVERY ONCE IN A WHILE, A NEW TOOL COMES ALONG THAT COMPLETELY CHANGES THE FACE OF MATHEMATICS." I was promised a chance to see this new tool... It was the TI-89 with a face lift and a few upgrades. I felt cheated:P
Slashdot Mirror
I'm probably jumping on the wagon late here, but here it goes.
;)
Microsoft will allow IT managers to block devices such as USB memory keys and - shockingly! - iPods.
Believe it or not, this cannot be construed to be an anti-iPod move. Giving people the option to not allow iPods does not an iPod ban make.
Slashdot, blahblah, kneejerk, blahblah, Microsoft, blahblah.... You get the point.
And congratulations to me for my 101st post!

Probably only semi-conjugacy... Some ideas are pretty twisted :P
Anyone else misread this? If the amount of computing power were shrinking, I'd say we're all doomed...
If even root cannot write to your ReiserFS partition, then you've got it set in /etc/fstab to mount read-only, I think.
Who here actually backs up their DVD's or CD's?

Just because you can't emerge it doesn't mean it can't be installed the old fashioned way, right?
I've found that Evolution has all of these features that you speak of. Well, except maybe the journal. :P
Copyright issues would be hell...
Google agrees with the article...

Does MandrakeMove use transparent compression like Knoppix?

Except much LARGER... Slashdot users have at most six digits in their UIDs, but this board has 5.4 million users (not hits)... Incredible.

Um, I'd be willing to write a review for a free laptop... Just email me...
./configure

Someone had to do it

Do I smell prior art? Here, let me be your patent lawyer...
Isn't that song a cover of something from the fifties? J. Frank Wilson and the Cavaliers. It was their only hit.
