It depends on the meteorite being studied. When a meteorite is discovered, scientists can study it and compare it to moon rocks. They can compare the composition and makeup of the rock with the moon rocks and they'll find that the meteorites bear a strong resemblance, thus making it probable that it came from the moon.
For Martian meterorites, they can look at a few other things. You can first check to see if it's igneous. That indicates that it might have come from a place with molten rock and it solidified at some point. That in turn indicates that this came from a planetary body. Now that you've established it came from a planet or a moon and not the asteroid belt, you examine other things. The meterorite might have gas bubbles in it, so you compare the composition of the gas with your knowledge of the atmosphere of other planets. In the case of ALH84001, they may have seen that the rock had lots of Fe, like Mars, and that it had gas bubbles which matched what previous landers on the planet may have observed. They then come to the conclusion that the meteorite in question is probably from Mars.
As for your other questions, the wikipedia article rightly points out that ALH84001 might have been contaminated. That's why you see articles like this peppered with maybe and probably every few words.
What would be more appropriate here than Java? Obviously not Mono/.NET Compact Framework, that's going to be years behind the 'latest' Android OS version. Obviously not ObjectiveC, as it's not a language but a joke.
I know I'm going to sound like a naysayer, so, hey, I may as well nay say.
Google's probably going for a tablet as well, so 2010 will likely be the year of the tablet - in the form of iphones and iclones, with much larger screens, the next must-have at the coffee shops. But it's going to fall flat on its face. It's too close to netbooks, but not as useful as a netbook.
Two scenes in particular. The first where she's teaching him how to 'fall' and use the leaves to break the fall. The second was when they introduce the "last shadow" pterodactyl. My thoughts, out loud, were "I wonder where that's going to be used in the story."
I saw someone rolling his eyes so much they became unscrewed and he had to be taken to a mechanic.
Saw it in 3D at the Imax. I think that this movie is visually appealing, and that's what it was made for. You're not supposed to actually pay attention to the story; it's a mix of Dances with Wolves and Fern Gully (and potentially about 30 other movies in which this concept of gung-ho-soldier-meets-and-loves-the-natives has been done to death), although it does strike chords with a few present day "situations". The main appeal is the graphics, the atmosphere, surroundings and facial expressions of the macrosmurfs.
Part of the hype was that Cameron spent 8 bazillion years working on this movie and that's another thing that spoils it, you expect something great and wonderful and almost Star Wars like, but you get another popcorn movie, albeit an expensive one. With blue people.
The UK has started already. From some news article: "The government's newest attack against online piracy, the Digital Economy Bill will force Internet service providers (ISPs) to monitor users and penalize infractions." Although the ISPs are protesting it, it's going to go ahead anyways and it's going to up our broadband charges. While slashdotters may complain about the US' poor mobile plans, the UK has far worse broadband plans. We already pay too much for bad service and now we're going to pay more for even worse service.
No, I was just wondering why a crypto/technology security expert would be considered an expert at security in aviation - was it just because he has the word security in his title? Of course, being on/., I thought it fit to express it as gracefully as possible. But then Bruce Schneier saw my post and modded me down.
Even better - how could we forget Songsmith? That was a point so low, it had its own gravity well and Hawking had to write a theory about it. They'd do well if they went "out there" to some of the more creative users for ideas and such; interacting with the userbase could help a bit and would have prevented the Songsmith or Windows 7 cringefests earlier on. And it's not that hard to find... Example
Point being, they need to think beyond the boundaries of Redmond. Just because a manager approves one of their adverts doesn't mean the public will...
Clearly, this is a devastating experience for aforementioned individual, as they are unable to procure an iphone. In fact, there is a potential that an entire city may be denied the presence of the iphone. Here at slashdot, we feel their pain.
(Assuming he did go through Amsterdam airport security) Part of the problem at Amsterdam airport is that they do tend to rush security checks sometimes. Often, I have seen them open up the security checkpoint at the gate just 20-30 minutes before the flight is due to depart. The security guards are then in a rush to get everyone across and so the scans and bag checks are hastily done. This Nigerian might just have been 'lucky'.
Though you joke, 2010 might be the 'year of the tablet' - Apple will come out with an iTablet and thousands of mactards the world over will decide that a tablet is an important device to have in their digital lives. Forget that they'll only ever use it to tweet about how wonderful it is to use the iTablet; other companies will soon decide that they need to create good looking tablets of their own that don't actually do anything.

I agree.

So all they need to do now is prove that 1 = 6.
There are already many other software based ereaders that exist, this one is just a bit more featured. Or am I being cynical again?
It took the author of TFA 3 years to realize it though. For that, we must applaud him. Next week, he's going to be writing about MySpace.

Nay, I say, nay

This came after Bono spent hours searching for his music on torrent sites. Apparently he still hasn't found what he's looking for.
I think you need to sperate facts from fiction.
Ye Olde Rofl.
Be thankful it isn't another iphone advert.
Dude, that's not cool, I hadn't seen this video before. I wish you would've just rickrolled us instead. Or at least a goatse.

Given that he has several books on security, his opinion carries some weight.
I'm a developer, does that mean I can work in real estate?

I weep for huge manatee.
I think it's all a steaming pile of crap. Get it? waste. heat. Oh, I slay myself.
I actually saw that one coming :D
