Oh, also, the purpose of a key exchange is *NOT* to protect you from an MitM. The purpose of a key exchange is to protect you from eavesdropping, since with a key exchange no unencrypted data *EVER* appears on the wire or in the broadcast. With an MitM, that wouldn't matter, since an MitM could intercept the communication and pretend to abide by the key exchange protocol for both sides, using the opportunity to actually acquire the encryption sequence that is to be used for the remainder of the transmission. You can't do that if you're only eavesdropping, because you're not actually sending any counterfeit data into the system.
More probable is that they would use an RSA-based key exchange, which cannot ever be solved in polynomial time (because you never see either party's key in the transmission)
Is it really so hard to use an encrypted key exchange, such as DHKE, to establish a completely private connection on something that you are broadcasting, and do not know who might be listening in?
Such key exchanges practically scream "USE ME" for situations like encrypting anything being transmitted over the air, such as cell phone usage.
Of course, it also means that the police wouldn't be able to listen in either without setting up a fake cell phone tower to be a MitM, at least not until somebody develops an other efficient algorithm to solve the discrete log problem, or unless they had a quantum computer on the job that is more powerful than any ever yet built,
Yeah, I know that cats aren't completely color blind, but they only have about a tenth the density of cones in their eye as a human with normal vision does, and to us, such imagery would look highly desaturated.
While it might sound all cool and stuff to make glass that thin, is there any practical applications for it? Or is this just one of those weird inventions that serves no real purpose but to satisfy intellectual or scientific curiosity?
... What I would like to see on game consoles is the ability to whitelist or blacklist games, regardless of rating... and games which are not explicitly whitelisted would use the default parental guidelines for what games can be played on the device without a password. Games that are explicitly blacklisted could not be played on that console. Many "T" rated games, for example, are perfectly fine for younger kids... but every once in a while there's one that sort of pushes the boundaries a bit, and one is called to question why it wasn't rated "M". Similarly, although a lot of "M" rated games are unsuitable for pre-teen children, there are a few that I've played that are not actually too bad... especially for the slightly older kids. Believe it or not, this is really a lot less about me being a lazy parent than it is about simply wanting to diffuse arguments before they happen. Kids just don't always happen to share the same values as their parents, and I'd just rather not fight with them about it, if I can simply do whatever I can to not have games I'd rather not have my kids playing being played under my roof.
In an ideal world, I could just tell my kids that I'd really like it if they wouldn't play game X, or download songs or movies off the internet, or what have you. In the end, however, my feelings are unfortunately not valued as much as what they personally deem important to themselves.
So, maybe I'm just a mlitiant parent... doubtless some would probably call me a control freak. Personally, however, I really just want peace in my household... and if a technology can help me silently close the door on things I don't want my kids doing, at least while they are under my care, without me having to argue with them about it, then I'm all for it.
I'm not entirely sure if you're being serious or not.
Nonetheless, assuming you are, your sense of up/down is actually derived from gravity, and not merely spatial positioning. Since gravity is always pulling you towards the center of the earth, you cannot perceive any difference in your orientation with regards to what direction is up.
However, if you use a specific star as a reference point, and look at how high in the sky it is at a certain time of night at on a particular day of the year at each location (or, if you are feeling lazy, use the north star, which has a roughly fixed position in the sky, so the time of year and time of evening won't matter), then you should be able to logically convince yourself that, when you are at different lattitudes, the direction that you call "down" has genuinely changed..
It's less a matter of works whose copyright status and owner are not well known that are considered likely to be infringing and more a matter of big-name copyright holders like Adobe, Microsoft, and others, who almost certainly did not give any permission to people be uploading copies of their commercially sold works onto MegaUpload for other people to download. If anyone has proof to the contrary, they should probably step forward.
Somebody develops a new sharing technology or service that people can use for legitimate purposes.
Its effectiveness is such that it eventually draws the attention of the piracy crowd.
Eventually, piracy is the dominant use of the service.
The service gets shut down.
Basically, what they are encourage people to do is not ever invent anything new or innovative, ever again, because when it gets used for illegal purposes, it will be shut down.
Can you imagine the ramifications of, say, technology-enabled telepathy?
You can doubt it all you want... but that doesn't make it any less true. It's fairly trivial to show show that a vast majority content on megaupload was copyrighted, and unlikely to have been uploaded to it with any permission from the copyright holder.
And just imagine the copyright violation potential! You could be arrested for even *thinking* of music that you hadn't bought a license for! Man, the RIAA is gonna be so into this.
Allow disabled people to use a computer without a keyboard
Sending email or a text message without even having to use equipment like a cell phone (for example "call my lawyer, I'm being arrested for looking Arabic!").
Perhaps you had failed to notice that the remark was tweeted while they were still in Britain... and several days before they even arrived at the airport.

How do be a MitM on a radio transmission?

You can't readily be an MitM for OTA broadcasts though, unless relays are involved, and you can guarantee to be able to fake one of the relays.

Does that mean it's using two ARMs at once?

No... it's about adding thermal energy, which by mass/energy equivalence ends up causing the earth to actually be more massive as a result
Yeah... but this tree only burned down a couple of weeks ago.
You live 5 minutes from the park and you don't know if your kids were old enough to remember seeing it from the last time you went there?
How is this even possible? Did they, like, never go outside or something?

Where, exactly, is it advertised that Megaupload is intended to share content that the person uploading does not have any rights to?
So let's see if I have this straight...

If you can visualize that, then you have other problems.
Oh, they understand them all right... they just usually couldn't give a f***.
Man... the 21st century is gonna be so cool!
Did anybody else think that this sort of technology could really help with detecting lies?
Or on the moon.
It's not like the US is going back to the moon anytime soon.
