From the article; "Nvidia has had its CUDA program for several years now to assist developers that want to harness their graphics engines for computational applications."
Nuh uh. CUDA is new with the G80. They may have had something going, but it wasn't cuda.
As for being disruptive -- maybe using the GPU for computation will speed some things up -- those things that are extremely parallelizable, and single precision FP -- thats about it. The GPUs are not easy to program to -- CUDA is pretty tricky, and it's fairly well tied to nVidia's new architecture (I don't see ATI adopting it). The stuff from PeakStream and RapidMinds is a bit higher level, and can work on both ATI and nVidia chips, both have their pros and cons. It's early days yet for this -- I don't see it catching on in a big way for another couple of years. Then I think it will catch on in a big way -- but the tools are too immature at the moment for that to happen, and it's hard to predict what is going to catch on. Anyone interested in this stuff should be paying close attention to all of them -- I know I am.
What if one of the things you decompose that hard task into becomes "prove P==NP"? (yes, I have seen effectively that in a real project, where the hard things were not tackled up front) Not all hard tasks decompose easily -- sometimes the decomposition is itself a hard task.
The way I look at it is that every "research" problem (one that has never been solved before) you face is like a bullet in a relvolver you're going to play russian roulette with. Whatever you do, don't even bother starting a project where all six chambers have a rounds in them. And if you're going to be playing this game, do everyone a favour, and blow your foolish brains onto the wall (metaphorically speaking, of course:-) before you waste too much of everyones time and money. This is to say, solve the hard problems first, before things get expensive. Sometimes you'll find you're not going to be able to pull it off. If you do solve all of them, you're going to have a much more predictable and lower risk project on your hands to complete. People who control funding for such projects really appreciate that.
Leaving the hard stuff until the end is one of the major signs of a project that is going to implode spectacularly. (I've seen this particular pattern a few times now)
(I also can't believe that I actually got around to posting this:-)
It's 15000 btu/hr for each burner. And yes, I have used all at once -- although not all on high at the same time:-) Forgot the/hr part -- most people assume that, in the absence of the time unit in this context,/hr is the sensible thing to assume.
My gas stove is 15,000 btu per burner -- that's 60,000 for the top plus another 30,000 for the oven. (Needed a new gas meter when it was installed:-) It's just a small (30") Viking.
If you work out how many amps of current at 240V that would be, it will surprise you -- You'd need to run awg 3 or 4 wire to your stove to get that kind of heat from electricity (without heating up the wires to the point of setting your house on fire).
For those interested in the numbers, it's 109.875 amps at 240V to get you to 26,370 watts == 90,000 BTU/hr. To compare, a typical electric stove of the same size will not draw over 40A at 240V.
Depends on the efficiency of your gas furnace. If it's very efficient (96%), The heat from gas is 47% of the cost compared to heat from electricity. (At today's prices in Toronto -- yes, I actually did the math). So for every dollar you save in electricity in the heating season, you're spending at least 0.47 on gas. If your furnace is not a new high efficiency unit, it will be more -- as much as 20% more.
Lets see -- I can think of a few just from the top of my head,
iTMS FairPlay allows you to;
Copy a tune to (and play it back on) any number of iPods. Copy the tune to (and play it back on) five different computers. Burn the tune to a standard Audio CD any number of times.
- The resulting CD has no DRM and may be ripped, encoded and played back like any other CD.
Does the Zune system let you do any of those things?
Question: Do you plan to implement a functional ad blocker (not just a pop-up blocker), or implement a plugin architecture that would enable third parties to implement such a blocker?
Background: Ads are so annoying, and once you get used to firefox with the Adblock extension, it is *painful* to go back to seeing all those flashy animated annoying ads. So if your answer is no, I'm afraid I will never use IE7.

They need to stop off at Alexandros (best take-out gyros in Toronto -- Danforth and Logan -- just behind the statue of Alexander) to pick up some tasty replacements.

Houses don't need to be designed for HE furnaces -- they can be installed in ANY house with a forced air heating system. But they do need to be installed *correctly*. (vented and drained -- they need to suck in outside air, so you need two pipes, and they produce quite alot of water from their condenser as it extracts the latent heat of condensation from the exhaust gases -- composed mainly of CO2 and H2O. This liquid water needs somewhere to go.)
Yes, everything you say is true, but (at least here in Toronto) electricity is one of the more expensive ways to produce heat. For the purposes of heating, natural gas is about 1/3 the price on a watt for watt basis. So while you're right, those incandescant lights are not making "waste" heat in the winter months, their heat is 3x more expensive than that produced by your furnace. You will still save money by using more efficient ways of producing light.
(And before you tell me that some percentage of my furnace heat goes up the chimney/out the exhaust, yes, some does -- 4% of it, to be exact -- I have a new high efficiency condensing unit.)

Ok, I went and did the math (assuming, on average 1035 btu/cubic foot of natural gas) Looking at my bills,
/kwh.
Natural gas is (cdn)$0.278287 per cubic meter, and electricity is 0.058
At 96% efficiency, natural gas works out to 0.027331 / kwh, (3413 btu in 1 kwh) or 47% of the cost of electricity at today's prices in Toronto.
So 1/3 was a bit of hyperbole, but not too much.
Yes, everything you say is true, but (at least here in Toronto) electricity is one of the more expensive ways to produce heat.
