Nope, I looked through the first three pages of power supplies (sorted cheapest first) on Newegg and every single on of them was labeled 100-240V, 115/230V, or 100-120V/ 200-240V. Those start at $11 so I'm not sure it's possible to buy a PC power supply here that's not capable of operation from 100 to 240V. Most of those real cheapies have the switch but go up to the $50 range and over half are auto ranging, $80 and almost all are.
Voltage already varies greatly, from about 475 to 495 on my 480V nominal input according to the monitoring device on the automatic transfer switch in my datacenter. The peak is usually during the summer when they are trying to push more power through fixed sized transmission lines. In fact during the day it's rarely below about 485V.
Yep, all of my UPS's do double conversion as it's much better for dealing with spikes, brownouts, and as you pointed out bad generator output. If you're looking at APC equipment you want the RT series of SmartUPS at the low end (everything higher is going to be double conversion by default I believe). My remote office guy didn't understand my insistence on getting the RT's until I explained the difference to him but I've definitely made a convert out of him.
Basically everything computer related is 100-240 auto ranging and has been for a decade or more. TV's might not be if they are designed with built in tuners because they have to change the tuner for other markets anyways so changing out the power supply is no big deal.
IMHO they make the best mobile browser out there, and since almost all the carriers are now going with draconian data plans it makes tons of sense to use their compression and resizing model. I was never a fan of their desktop browser, but I'm glad they were there as most of the other players stole some of their best ideas and incorporated them into browsers that fit my style better.
Partnerships are nothing new in the auto industry, Daimler-Benz, Ford and Mazda, Ford and Volvo (the new Taurus is build on the same platform as the S60), etc, etc. Doing all the design and validation work for a new auto platform costs a LOT of money, spreading those costs over the most units possible just makes sense. This is especially true in areas where your company has not historically been strong because a fully modern design from scratch takes so long that it's often outdated by the time it actually gets into production.
Crap fuel economy and engines that fairly regularly need two headers worked on, no thanks. I was seriously looking at a used Subaru but between the fairly high used prices and the potential for an ~$2800 engine job needed I've decided to get my first new vehicle. I'm leaning toward a Chevy Equinox, 27mpg mixed with AWD.
And it's not just sensor size, the larger the magnification of the lens the shallower the DOF (generally). The DOF on my 150-500 at 400-500mm is really shallow making shots of anything moving in less than perfect sunlight fairly difficult.
This isn't primary defense (at least not in the Navy's eyes) it's point defense for whatever makes it through the rest of the fleet defense curtain. It's to make sure a rogue Exocet or two doesn't take out your multibillion dollar one of eleven carrier.
This is why the Gerald R. Ford-class carriers were designed with way more generation and distribution capacity then they currently need, the Navy knew that directed energy weapons were the future of point defense systems. It may be free electron lasers or perhaps some kind of rail gun, or perhaps something else, but it seems unlikely that the chemical powder based system at the heart of CIWS will still be in use in 60+ years when the Ford is retired.
Well, a benchmark with 2012 in the name certainly shouldn't be using two non-GPU accelerated web browsers and Acrobat 9! They really do have a point that currently released software is doing a much better job of using their more well rounded systems then the benchmark is. It's a system benchmark not a CPU benchmark (we have SPEC for that).
If you're in an area where Sprint has strong coverage then you can get Virgin Mobile for $25/month, 300 minutes of voice and unlimited text and data, no other fees other than local taxes if applicable. I'm literally paying the same per year for my wife as I was when she was on a T-Mobile $10/minute pay as you go plan with obvious a lot more functionality, she's a very happy camper and I have a small, predictable bill.
No, the best plan is Virgin Mobile (Sprint), $25/month 300 minutes, unlimited data, unlimited texts, no additional fees except local taxes. It doesn't allow roaming though so if you don't have good Sprint coverage where you live it obviously won't work for you but they cover like 80% of the US population so it should work for most people.
I roam at 3G to VZW using my Sprint EVO Shift, some people have reported that you used to only be able to roam at 1xRTT speeds but I've normally seen EVDO.
The problem with all of those arguments is that if you don't agree to the GPL you have *zero* legal right to use the code, in whole or in part (unless it doesn't meet some copyright test like API headers with no creative value). It's a well written legal contract and a LOT of companies with large legal teams (like Cisco for example) have looked at it and ultimately caved because they couldn't find enough of a loophole to drive their case through, I doubt a company that has needed to change their legal strategy twice is going to defeat it.
Wow, after reading up on the VIIIfx I take back what I said about ok chip, the thing is an HPC beast. 128GFLOPS in a 58W envelope is crazy good. Increasing the dual precision FP registers from 32 to 256 is huge, this is obviously not a chip designed to go into Sun or Fujitsu business class system but tailor designed for HPC (heck going from the VII to the VIIIfx they actually lost L2 cache while increasing the core count, not something you would do for commercial workloads). I wonder if it is worth it for Fujitsu though, 80k parts is a big single order but unless they get a lot more HPC wins I can't see it paying off financially as modern designs like this cost hundreds of millions if not billions of dollars.
Huh? The K Computer was built by Fujitsu, and contains more than 80,000 2GHz SPARC64 VIIIfx CPUs, each with eight cores, to deliver a total of more than 640,000 processing cores.
That said I'm fairly surprised that it managed to be the 4th highest efficiency system, the SPARC64 isn't really known for being a hugely efficient and the low density of FLOPS/chip would normally mean it needs more support infrastructure further lowering the efficiency. Obviously the guys at Fujitsu have managed to do some great system engineering since Rmax is so close to Rpeak, kuddo's to them for making an awesome system around an ok chip!

Microsoft called theirs shared source which is probably a good description.

No but a double conversion UPS with true sine output might (haven't looked into how they generate timing but I assume it's quartz crystal).

$41,695 for an electric Ford Festiva, yeah I can see why that didn't sell well.

CUV's are wagons with a raised suspension, good if you want to go through a couple feet of snow without the awful fuel economy of a full truck.

VoIP has *always* been dicey over cellular networks due to high latency and jitter.

You don't think private property rights are a cornerstone of capitalism? That must be a very different definition than all the ones I'm familiar with.

Not really, the Nexus was the first phone to get it and that was less than 4 months ago.
Funny comment considering my Sprint EVO Shift just downloaded Gingerbread this morning =)
