So Musk himself decribed it as a "cross between a Concorde and a railgun and an air hockey table". So why do people keep talking about tubes ?

Wouldn't a Ground Effect Vehicule (http://en.wikipedia.org/wiki/Ground_effect_vehicle) fit the descripton better ?

Edit : thought a self powered super-sonic GEV would be hard to pull of.

one of the more appropriate links...https://en.wikipedia.org/wiki/A%C3%A9rotrain

Until August the 12th at the most.

He didn't say the tube were going to be evacuated did he ? If you are going to put something in the air, evacuationg th lauchpad seem to be a bit pointless.

Hum... How about her gender colors her perspective but is not the issue ?

Gender affect a lot of your environment and your education so you can't escape it's influence. But in this case gender is not a significative parameter in one's perception of Linus and his strong-mouthness.

No because Amazon didn't force plublisher to change price. They used reduced their own margin do be able to sell at that price.

It seems to me that as far as international rules go it's not an "abuse" of power. National airspace is, after all, national. You can refuse entery to a foreign president if you damn well please. (High ranking official have a very limited liberty of movment since every deplacment abroad is subject to authorisation of the receiving country.)

On the other hand once you have authorising them to cross your airspace usually grants them extra-territoriality. Meaning that for an reglementary standpoint you can't force a plane to land and search it. (No suspending authorisation once the plane is in the airspace, and you can't search the plane because it is considered foreign territory.

> In first world countries

Is that a thing outside the US ? I've never heard of it outside of US news.

I'm pretty sure they are people who beleives that in other countries. But do they get media attention like in the US ?

I don't think it is a talking point outside of the US (if it is, I have not been exposed to it), but people in the US do like to point out what they perceive as "a war on christianity" in other countries.

If the country in question is, I don't know, Cambodia, perhaps that is true (no idea if it is or not). But if the American christian fundamentalists are claiming that there is a war on christianity in England or France, then they are without doubt full of shit.

It seems like there is a certain brand of christian fundamentalist in America that really wants to think that the Romans are still tossing them to lions or something. They find that idea vindicating perhaps, I don't know. I don't get it.

Maybe i'm reading it wrong but I have the impression that the problem here is the notion of forward secrecy.

Forward Secrecy only garanties that given the master keys Eve still can't derive the session key. It says nothing about the scheme used to create the session key (which may not be safe) It only states that even if Eve gets the private key that won't give her any information on the session key. It's the "won't leek any information" part that makes it "Perfect".

"Prefect" is used in the same way in "Perfect Information-Theorical Security" (http://en.wikipedia.org/wiki/Information-theoretic_security) were the Info-Theoric Security is perfect if the cipher text doesn't leek any information about the plain text.

The use of the word perfect seems consistent to me. The problem is actually understanding what we are talking about and what part of it is Perfect.

So, the actual scheme is authenticated Diffie-Hellman key agreement. Its security is based on the discrete logarithm problem---it does not provide perfect information-theoretical security.

"Forward secrecy" is an accurate term. "Perfect" is redundant and potentially misleading.

Half-Life 2 (or so i remember)

Are you referring to the episode 1, episode 2 stuff? It's just a bunch of different games, that were released seperately.

If you look his Orwin Gambit start it would happen. It's because this the first move is done freely so you end up with one area ahead of it's paths (ie full but with only 8 path already taken).
