Comment Gedankenexperiment (Score 1) 315

Suppose we imagine the following: a large room with a level floor, with no open windows and still air all around. Put the proposed cart down somewhere. From the cart's point of view, there is a prevailing wind of zero no matter what direction you've placed it.

Now the claim is that the cart can go faster than the prevailing wind. So once you place the cart down, it should move on its own. Now just where did it get the energy to do that??!

Submission + - How Star Wars trumped Star Trek for scientific acc (shadowlocked.com)

An anonymous reader writes: When George Lucas added the 'ring around the Death Star' effect to his 1997 re-release of Star Wars episode IV: A New Hope, the revision was almost as hated as Greedo shooting first, and to boot was seen as a knock-off of the seminal 'Praxis effect' in Star Trek VI: The Undiscovered Country (1991). But a debunking astronomer claims that the Federation got it wrong and the fan-boys should thank Lucas for adding some scientific accuracy to his fictional universe.

Submission + - Futurama Writer Creates New Math Theorem (geekosystem.com)

kevin_conaway writes: In the latest episode of Futurama, writer Ken Keeler wrote and proved a new math theorem based on group theory. From the article:

We all knew the writing staff of Futurama was brainy, but this is something else. In the episode “The Prisoner of Benda,” the Professor and Amy use a new invention to switch bodies. Unfortunately, they discover that the same two brains can’t switch twice and have to come up with some equation to prove that, with enough people switching, eventually everyone will end up in their rightful form. To work out the ridiculous brain switching plot line, writer Ken Keeler (who also just happens to have a PhD in mathematics) ended up writing and proving an entirely new theorem

If that's supposed to be the number of bytes on a disk, it must have been a strange-looking creature.

First we factor out 512 bytes per sector. That leaves 2874. Now 2874 has a prime factorization of 3 * 13 * 73. Since those are all prime the best possibility is that you're describing a three-sided floppy with 13 sectors per track and 73 tracks. (Or is that a 73-sided floppy with 13 tracks of 3 sectors? There are only 6 possibilities, none of which make any sense.)

When you give computers to the public they usually get abused. In my experience computer lab, and library computers are more messed up than any computer I have at home.

But yes, assuming they treated them like you and me, I think it would be a great idea. It would give us peace of mind, and decrease cyber crime.

They can do both, and the two goals reinforce each other -- the skills to do both are pretty non-overlapping anyway. For me, the streaming has been a non-starter so far because I run a MythTV media center and own a Wii -- the only place I can use the streaming right now is on my laptop (a Mac), which is not the best movie viewing machine.

This brings me into the market now, and makes me think that when I move out of my current place (the account is in my roommates name) I'll get my own subscription as well. Assuming I'm not a total outlier (not many people will have MythTV, but there are many people with only a Wii, DVD player, and crappy cable box attached to their TV,) this greatly expands the number of people using streaming, and will thus encourage content producers to see that they need to find a good way to monetize streaming video.

Just because this doesn't benefit you directly and in particular, that doesn't mean its not worthwhile, and in this case a rising tide raises all boats.

I was in the U.S., but I don't remember any backlash against Arab-Americans.

Just because the media you watch or read didn't report on it, doesn't mean it didn't happen. Tea party protests where 2,000 people show up get more attention than an anti-war rally in 2003 where 200,000 people showed up.

Comment Re:This is why I love competition (Score 0, Flamebait) 77

When iPhone came on board with games, etc, I knew there will be potentially improved products from Nintendo and eventually Sony/Microsoft.

So Nintendo is only innovating their handheld because of competition from the iPhone? What about the Game Boy Color, Game Boy Advance, Game Boy Advance SP, Game Boy Pocket, Game Boy Light, Game Boy Micro, DS, DS Lite, DSi, DS XL....?
