'In three years' time, 20 typical households will generate more traffic than the entire Internet today.'
I don't know about the typical household, but personally I don't think I can watch that much porn.
"The more you desire to download, the more you will have to pay." That's fair so long as they advertise that fact. But no, they'll lose business when everyone else is offering "unlimited".
Yes. It's fairly prevalent in University of Texas. I use the software to post grades to my students (not by my choice). It's such a pain to upload grades. There's a feature to upload grades from a file, but it requires doing it line by line and requires too many page loads. It's not terrible software; just not that good.
Now this nuclear safety officer is just being silly. If high energy particles could really create black holes which would swallow up the Earth, wouldn't it have happened already? We are constantly being bombarded by high energy particles. The fact that we are still here makes it hard to believe any little experiments we do here will destroy the Earth or more.
10 watts less operating power. Wooptie doo. What I want to know is, how much less resources are used in production, and how much greener are the waste products.
In the future, we may not need keyboards, since some better input system will be developed. You could envision a touch chord system which doesn't require location accuracy. Better voice recognition or brain recognition. Letters could be formed by a variety of gestures. Typing doesn't have to be an up-down motion of the fingers; it could be various finger gestures which don't require pressing down a button. There's no reason why a new system would be slower than traditional typing.
The low pressure sodium vapor lamps that are ubiquitous in streets of USA are already pretty efficient (80-180 lm/W according to @everything2 and up to 200lm/W according to wikipedia). The impressive thing about the new light bulb is the purportedly white spectrum. The sodium street lamps paint the city an ugly orange-yellow.
It's not that clear from the article how they are defining efficiency, but if they are claiming that they are converting 70% of heat energy into air flow energy, simple thermodynamics can tell you that that is bullshit.
If you assume an ambient temperature of 300K, then you need a temperature of 1000K MINIMUM to achieve 70% energy conversion. The Carnot efficiency is 1-Tc/Th, which is the best efficiency possible for a heat engine. Typical heat engines are a fraction of that efficiency.
According to Einstein's equivalence principle, the local physics of a constant accelerating frame of reference is the same as the physics of a uniform gravitational field. This equivalence is so powerful that if you accelerate for long enough, the physics are like if you were stationary in space near a black hole. You expend fuel to accelerate in empty space, just like you expend fuel to stay stationary near a black hole. Moreover, you actually can see a black hole behind you in an accelerating reference frame, and it even exudes Hawking radiation.
This latter effect is explained by the Unruh effect.

Bad idea. I suppose that would reduce the efficiency of your heat sink. If you are trying to get heat out of your chip as quickly as possible, the last thing you want to do is put a dam in the way.
It seems like all the included Republican statements are just short, empty generalities lacking any a clear plan (except for gun control, which was also short but to the point) whereas the Democratic positions are much more defined. Is this due to bias from the editors or are the Republican candidates just that vague?
Either they are that dangerous, in which case lock 'em up and throw away the key, or they aren't Talk about a false dilemma. You are saying there's no case of someone who is a little dangerous, but not dangerous enough to be useless deadweight to society?
Only a Sith deals in absolutes.
I have issues with OSOD but for different reasons.

Base it around comprehension of a passage of text rather than some image which blind people can't see.

After all this time of silly politics or pointless reruns of DMCA or copyright cases, finally, we have some refreshingly nerdy news for nerds.

Why would medical ethics stand in the way? You aren't harming anyone.

No need to set up a dichotomy here. Just boo them both.
Don't be a buffoon, of course sexual preference depends on gender. You think it's social conditioning that most males like girls and vice versa?

I wonder if by posting these ideas on /., this will actually _be_ done now. There's a good chance the crackers (or some copycats) read /.
If you think about it though, almost every technology can be a weapon. Sucks though.
This has got to be a fallacy of some sort, arguing that 16 billion is a bargain because other costs are so much more expensive.

Yup, it got blown out of proportion because in the business world, data is more valuable than people.
Yes, they start to collide with the microwave background radiation. I can't cover it as well as wikipedia: http://en.wikipedia.org/wiki/GZK_cutoff
Religion causes psychological dependence, which is harder to break.
