The quickest numbers I could find say that at the scales of large power-plants, the generator is very efficient, but the turbine not so much, around 50%. This would put the system as a whole at around 40% efficency sunlight -> electricity. That's competitive with the best solar voltaic systems tested in the lab, and 50-100% better than practical systems on the market. Assuming their system really does scale up to power plant sizes, of course.

It seems that the launch site has been rather precisely determined. Perhaps you missed that memo.

And no matter how much evidence the US or Ukrainian government produces, no matter how detailed and annotated, Russia will dismiss it with a wave of a hand as fabricated, slanted, biased...whatever they want. They'll never admit responsibility.

What they need to do is to organize UN peacekeeper mission there, not wage proxy war with US.

Yes, because UN peacekeepers have such a long, sterling reputation on stopping stuff like this from happening.

But regardless, the UN will never do anything in this conflict. Russia holds a veto in the Security Council, and they will stop any such measures from ever happening.

Imagine long range trucking where the vehicle didn't need a driver and wasn't subject to driving limits. It would make trucking a lot more competitive against trains.

It would also make automated trucking a lot more competitive against human driven transport services...thus the unions will immediately be against it.

We'll have more information about the gravity attributes and locations of dark matter,

Both of these experiments aim to detect collisions of dark matter particles with their respective detectors, and if found give an estimate of the particles energy. Neither are astronomical surveys that would tell us anything about the gravitational properties or distribution of dark matter.

I would even argue that as long as the students who did most of the work have their name listed as first author, there is nothing wrong with this arrangement. I dropped out of my master's program after the first semester because I was being pushed to publish, but wasn't being plugged into any research existing programs. Every "unique" idea that I thought of turned out to have already been studied exhaustively back in the 70's or earlier. All the favorite students in the grad program were people who ignored this inconvientent fact and managed to get rehashed bullshit accepted into conferences.

Several years later I went back to school at a large state U that plugged me into the work they were doing, showed me what the state of the art was and where there were gaps that hadn't been researched in detail. Without building off the ideas of my advisor I would have never been able to do meaningfull research that progressed the state of the art, and would have had nothing worth publishing. He deserved to have his name on my papers.

+ - The Government Can No Longer Track Your Cell Phone Without a Warrant 1

Submitted by Jason Koebler
Jason Koebler (3528235) writes "The government cannot use cell phone location data as evidence in a criminal proceeding without first obtaining a warrant, an appeals court ruled today, in one of the most important privacy decisions in recent memory.
"In short, we hold that cell site location information is within the subscriber’s reasonable expectation of privacy," the United States Court of Appeals for the Eleventh Circuit ruled. "The obtaining of that data without a warrant is a Fourth Amendment violation.""

OP:

... when configured to boot straight into Steam Big Picture mode, the influence of the underlying OS is visible only in the larger game library.

... and the considerable additional maintenance requirements that go along with a full fledged operating system. Considering that Windows has required more frequent patches for security issues than Linux for the past few years, that's not a trivial distinction.

PP:

With Windows on it, this little machine can fulfill most of my needs for the living room / home and offers me a platform that i am already familiar with to play my games, (Steam supported or not), get some work done (Office etc) and watch movies.

While this is a valid point, it is a realization of this change in paradigm. With Windows 8.1, it is a regular desktop computer, not a gaming console. While that gives you the ability to do office work and more, it takes it out of the single-purpose, dedicated function, "appliance" category that consoles usually fall in.

With Linux running as essentially an embedded OS, it's likely that updates would be less frequent, smaller, and less crucial to it's overall suitability if skipped. As an example, how long has it been since you've updated your smart TV or DVR as opposed to your desktop or laptop?

+ - Computer Chronicles Now Streaming 24x7 on Justin.tv

Submitted by Anonymous Coward
An anonymous reader writes "Some of us might remember the television series Computer Chronicles, created by Stewart Cheifet. It aired on Public Broadcasting Service (PBS) during the mid 80's to early 2000's and documented the rise of the personal computer from its infancy to the immense market at the turn of the 21st century. Last week, the unofficial YouTube channel ComputerChroniclesYT announced they were streaming past episodes 24x7 live on Justin.tv."
