Comment The economics are wonderful (Score 2) 241

Gee, a $1000 GPU that runs 7x as fast a 1/8th of an $1500 CPU. It woud be good idea if you didn't need that CPU to run it, but just barely so. If you cheap out on the CPU and only spend ~$750 on it, assuminng there is no slowdown on the GPU because of it, then the economics break. And people wonder why GPU compute on databases isn't catching on.

Then there is the power use aka TCO/running costs to think about. And everything mentioned above. And.... This study has all he hallmarks of an Nvidia research project who's targets are financial analysts rather than potential customers. The science is fine but that is not the intent.

The "audio" in question is most likely all below 24 kHz, that being the Nyquist limit for the 48 kHz sampling hardware, unless it happens that some phones can actually sample faster, and have microphones that can respond to higher frequencies.

The instruction rate of the CPUs in question is many times that frequency.

It doesn't sound likely.

TEMPEST was a details-secret government requirement meant to defeat means of eavesdropping on classified computer data from its electromagnetic emissions. I guess they need to include audio too.

My impression is that the noise comes from the power supply, not the CPU. I can certainly hear it with some computers, and it is related to work on the video card in my experience. I'm astonished that you can actually pull data from that, and in fact I'd like to see independent confirmation before I believe it.

Comment You are missing the point. (Score 1) 254

You missed the point, it is not a case of "My platform isn't quite as shitty as yours." this time around.

That said we have reached a state of meta-fanboi-ism, the new argument is, "The platform I don't have and have no real clue about isn't quite as shitty as the platform you don't have and have no real clue about." And for the record, yes this is yet another internet derived regresion of the human species.

Comment Story is a PR plant (Score 4, Informative) 224

I work with a charity that has access to the MS discounts and there is one authorized outlet for it, Tech Soup. MS has ALWAYS made the latest version available so this is nothing new. It is just an astroturfing post to try and drum up some good PR for the embattled and truly miserable OS.

That said why is MS so cruel to those in need?

Comment Drinking Water Isn't So Easy As You Think (Score 3, Interesting) 247

When I was a kid I did Unicef collection every Haloween. We got an orange cardboard coin box at school, and collected donations to it along with our trick-or-treat. Unicef used these funds to build water wells for people in Africa who had only access to contaminated surface water.

A decade or two later, we found that many of these wells accessed aquifers that were contaminated by arsenic. And that thus we kids had funded the wholesale poisoning of people in Africa, and that a lot of them had arsenic-induced cancers that were killing them.

OK, we would not make that mistake again, and today we have access to better water testing. But it caused me to lose my faith that we really do know how to help poor people in the third world, no matter how well-intentioned we are.

And we had better not go around curing disease withoput also promoting birth control. Despite what the churches say, and the local dislikes and prejudices. Or we'll just be condemning more people to starve.

Well, nuclear reactions that we can turn off like laser-initiated fusion are a lot nicer than the alternatives. The inside of your car engine is a raging inferno shot with electric sparks and compressed with inexorable steel cylinders. That doesn't keep you from going on a nice drive with your sweetie.
