The efficiency of electric motors is around 90%, so I'm assuming the fuel-powered pumps have such a low efficiency it's worth using batteries instead of fuel to save weight. These are also unlikely to have rechargeable batteries, so the energy density may be an order of magnitude higher than let's say rechargeable LiPO-batteries.
About 17Hz or a bit more with most single DVI outputs, although 14Hz is the minimum required for DVI by actual spec. Twice that with two DVI signals. The display itself does the thing by partitioning the display; either 3840x2400@14+Hz or 2x1920x2400@28+Hz side-by-side or 4x1920x1200@60Hz in a 2x2 grid, capped by the display at 41Hz or 48Hz depending on the model.
I have one of these (rebadged T221; ViewSonic VP2290b), got it second-hand in 2008 or 2009. It's not just the display connection bandwidth, the 41Hz and later-model 48Hz limit is from the display internals. They use huge custom FPGA logic chips to drive the signals, which are apparently not fast enough for more than that, although some of them can be overclocked to drive almost 60Hz. Without these internal display limitations, four DVI cables have enough bandwidth to run one at 60Hz (4x1920x1200@60Hz).
I haven't bothered to drive mine with four cables, because with just two (1920x2400) DVI signals I get it up to 34Hz, but I've scaled it down to 30Hz, because it's evenly divisible by 60Hz. In normal desktop use, it's fast enough. For gaming and movies, there are other displays.
Eventually there'll be a point in resolutions when it's bandwidth-wise better to have the GPU on the display side and just run some future thunderbolt-esque long cable than running even higher bandwidths to the display. An 8k display with a resolution of 7680x4320 would require 50Gbps of bandwidth to be driven at 60Hz at 8bpp or 60GHz at 10bpp. The actual required data rate between the CPU, RAM and GPU is much lower nowadays, especially because most of the heavy lifting like rendering and video decoding is done by the GPU.
This article isn't scary. What should be scary is that cell companies cell anonymitized _geolocation_ data. That data can be used to deterimine: A) who you are, B) where you live, C) where you work, and D) who your friends are. Step #1. Look where the phone is, regularly at midnight. Step #2, cross reference with public records databases on property ownership. That get's 65% of Americans right there. Now check where it parks every day at noon. Place of work found. And so forth.
Well, someone who wants a modern car isn't buying an american V8 anyway.
Shouldn't maintainers of compromised systems be held liable for skimping on security?
A long while back, after getting into Python development, I learned to always use the expand tab option (which always puts in the correct number of spaces to reach the tab stop when you hit tab) and never looked back.
Yeah. This guy's boss is an ass hat. The analogy involves a contractor. If that contractor wall-builder has employees, no, they don't actually work for free. Meanwhile, in addition to the labor rates the contractor charges, they'll have overhead for business operation, risk, and profit margin. So if this guy's ass hat boss is expecting that, then he should expect to pay a lot more for the work. Idiot.
There's a fifth level for ads. They create a background awareness such that when the demand does materialize, and you are presented an array of choices to satisfy the demand, you pick the advertised thing, simply because it seems most familiar. This is, in fact, one of the more powerful impacts of advertising.
The Free Software movement is not about money.
I know Henry. He's an enterprise storage guy. My guess is that he was coming from the perspective of enterprise storage builders. Which is to say, the Backblaze data may be a fine review of the experience consumers are likely to have with hard drives, it's a terrible review of what enterprise storage platform makers would do and what their buyers would expect. Whether or not that's an appropriate response to Backblaze, who intentionally and haphazardly uses consumer drives in their systems, is its own question. But what is certainly true is that you won't experience these kinds of failures from Tier 1 storage manufacturers (e.g., IBM, NetApp, EMC, Hitatchi Data Systems, et al). So in that particularly biased way, the study is indeed "deeply flawed".
No, the law hasn't changed at all. But that's not what they're referring to here. Amazon ships the item to a local dispatch point, and holds the final leg of the shipment until the last possible minute. If that final order doesn't materialize, Amazon is being charged for the charge to the local distribution point (and back).
iPhone 4 and newer iPhone battery replacement is fairly trivial:
1: Buy a battery and a pentalobe driver or bit from dealextreme or ebay for about $10
2: Uscrew the two case screws
3: Slide the back cover off
4: Unscrew the battery connector screw
5: Replace the battery and reassemble the back cover
I've done it about once a year on my iPhone 4, once the average recharge interval goes from about five days to about three days.
Huh? "firstname.lastname@example.org" is my account on every computer in the world as far as I am concerned. If someone else fraudently registered it, they can take me to court and see how well the court receives their fraud. Not well, in any non-barbaric country, I am sure.
