Probably none. There's no more reason for a vendor to make these boards more expensive than boards they're selling right now.
Adding a BIOS option to disable the secure boot feature doesn't cost anything, and it only increases the number of potential customers, so any sane vendor would include something like that.
One should remember that the first airplane flew only 120 feet but it was 120x better than what came before it.
You mean the second airplane flew only 120 feet, and the first one flew a foot.
And the point about 10x efficiency is well understood, but it would be nice if the old or new efficiency was mentioned in the article using some reference that could be understood.
That still doesn't mean much. It would be nice to know what percentage of incoming energy from the light is actually converted into splitting water molecules.
Does this compare favorably with a regular PV cell + electrolysis, for instance ?
Second, what is the cost and availability of the materials needed for the catalyst? Does this require some kind of unobtainium? The article is very vague here.
If I'm not mistaken, the materials are listed right there, in the abstract:
Ba0.5Sr0.5Co0.8Fe0.2O3
(Barium, Strontium, Cobalt and Iron, all abundant)
Low-wattage high-performance processors are actually critical for the server environments that Xeon currently dominates
I wonder which one is lower power, the ARM or the Xeon.
Of course, you'd have to measure the power for the entire server board, not just the CPU, and you'd have to measure the power based on the same workload.
You need a blind test. Ask a friend to play both samples for you, without telling you which is which.
Also, listen to the music under normal circumstances. You're not going to care if there's a noticeable difference under perfect, but highly unlikely, listening conditions.
According to the researchers, there's only 1 cubic meter of magma being added per second. If you drain it at the same rate, the pressure should stay stable. I'm not an expert, but that doesn't seem impossible to me.
No, I don't think oil is the same as magma, obviously, I was just comparing the numbers for reference.
I didn't intend on lining the bore hole. Just drill deep enough, and let the lava flow out. If the flow is big enough, the supply of additional heat should keep the hole open. If not, there's probably not enough pressure to worry about an eruption.
Not really. The poster was explaining that volcanic eruptions have a relatively short time effect on the climate. The first year after the eruption, the effect is big, and then exponentially decays with each passing year.
This means that a volcano is not going to give any kind of relief. A small eruption only means a few cool years before the global warming resumes on the old trend. A large eruption would cause a longer cooling period, but would kill most life in the first year. Either way, we're hosed.
There are no 'goldilocks eruptions' that would bring relief from global warming for a few decades, without causing substantial harm themselves.
No, climate models are mostly based on physical models. They are similar to weather models, except you let them run for a longer duration, and multiple times, so you can average the results. By averaging, you remove the chaotic noise, and only keep the trend, which is not chaotic in nature.
Of all the variables in a climate model, only about 6 are left that must be tuned with historical records. Compare this with economic models, where probably the majority of the parameters must be calibrated.

We can reasonably assume it was a better one than yours.

Not quite. The ALU was 16 bits, so instructions dealing with 32 bit operands were generally slower.
Just buy one where the vendor didn't implement any restriction.

Maybe DARPA's purpose is to build a better shredder, and this is just a cheap way to get it tested.
First shredding, and then incinerating would seem fairly fool-proof though.
True, but shit happens a lot faster if you make bad decisions.
If you don't eat so much, and take regular walks, your knees would last a lifetime :)
I think the French were just smarter to stay out of Iraq. How much did that cost the US so far ? And for no good reason at all.
I think enough people have common sense, but get blinded by greed, and join the party anyway.
Actually, the prime parking spots are on the other side of the lot, enabling you to get a healthy walk before getting back in the car.
McGyver's "facts" were mostly useless, in fact, and wouldn't have worked in the real world.
If falling pressure releases CO2, wouldn't the rising pressure force the CO2 back into solution ?
According to the researchers, there's only 1 cubic meter of magma being added per second. If you drain it at the same rate, the pressure should stay stable. I'm not an expert, but that doesn't seem impossible to me.
There's enough pressure to lift the entire landscape, so overcoming the weight of the column should not be a problem.
The ability to memorize useless facts isn't a sign of intelligence anyway.

It doesn't sound too crazy. The Alaska oil pipeline transports 4 cubic meters per second, and that's through a fairly thin and very long pipe.
Dump it on nearby surface ? Maybe preferable to waiting until it explodes.
