Sure; Windows 7 is bound to get a larger market share; but did the researchers also keep in mind that with Windows 7 professional and up you can easily run a native Windows XP environment within Windows 7 ?
That is... assuming the user has a CPU with the hardware accelerated virtualization needed to run Virtual PC.
Because the Pentium 4 was inefficient garbage. Assuming you leave it on all the time and replaced the board and processor with a Core 2 three years ago, you would have already made up the difference in power savings.
Conversely, if the truck driver IS tailgating, your car will not have had significant time to decelerate, meaning the impact velocity will be relatively small. A collision will occur, but assuming the impact does not upset your car's balance and cause it to lose rear traction, it will be fairly minor.
The simple fact is that HTML5 does not support DRM. If it wants to remain an open architecture, able to be implemented by anyone, it can never support DRM. That is why Flash has nothing to worry about until something better AND closed source comes along.
Exactly what I was thinking. What is stopping someone from setting up an application that does nothing but connect to random other machines and dump/dev/random down the pipe? Encrypted traffic through any well written algorithm should be practically indistinguishable from random data. Of course not knowing how the judicial system is set up in Pakistan, they may have the ability to imprison you indefinitely for doing such.
Eh? You don't need encryption to bridge two networks or set up a tunnel.

And the misconceptions shown in that chart is exactly why we cant have nicer resolutions. That chart details the normal resolving capability of the human eye (one arcminute). The lines he drew there indicate when a person with 20/20 vision would be able to fully resolve each pixel. It does not account that a significant amount of the population can naturally see better than that, nor does it account for the fact that another significant amount of the population wears corrective lenses to see better than that. It does not account for the fact that certain structures like two parallel high contrast lines can be resolved significantly smaller than that. It does not account for the fact that structures smaller than that can still produce visible aliasing artifacts.
Basically, someone somewhere took a couple minutes to find out the meaning of "20/20 vision" and decided that's all the better we ever need, without realizing that the human eye is far more complex than that single value depicts.

It's not, but they need new features to sell to get people to dump their existing 1080p sets.
Correction. This works in the absence of visible light. Just because something is not emitting light in the visible spectrum does not mean it is dark in the infrared spectrum.
This acts like an insulator. Given a sufficiently large heatsink, you could potentially do this. Within the confines of a laptop, it will simply cause a CPU to run hotter. A hotter CPU requires a higher voltage to maintain stability, which in turn consumes more power and produces even more heat.
I develop for a 9yr old C++/Qt project with some 27k commits before converting to Git last December. We've got another 3500 or so commits since then. It was around 110MB for the Subversion working copy, but ballooned to over 400MB for the Git repository. Now the primary code base wasn't that big of an issue. A bit of use of git-new-workdir and having multiple copies in different branches was really no more expensive than it was with Subversion.
However, things like our Apache interface only took up a couple hundred KB. Our primary web dev was accustomed to having a whole bunch of different versions sitting around to test various things. With subversion, a couple hundred KB and a couple seconds later, he has a new copy downloaded. Git simply doesn't allow for such operation. Carrying 100+MB and having to spawn a new branch just to test something out can be a big nuisance. In order to continue working in the manner he wanted, he had no choice but to split off into a different repository.
Git certainly has its uses, but it has its pitfalls too. There is no one-size-fits-all solution to anything, and Git is no exception.
It's not quite that straight forward. First, realize that gas turbines are a heat engine, and not a direct energy conversion. Further, gas turbines operate on economies of scale. The larger the engine and higher the compression ratio, the higher thermal efficiency you get. The 747 runs on moderately sized engines (55klb), that are 40 years old, with a fairly low 24:1 compression ratio. Total thermal efficiency is probably somewhere the low 30s, rather than around 90 for an electric motor.
Second, the efficiency of an aircraft is directly proportional to it's speed. Higher speed means shorter flights, but thrust requirements go up with speed squared, and power with speed cubed. Smaller personal aircraft operating at speeds around 80-120kts actually get comparable mileage to a large car. Slower flights would make the world a larger place, but may be more sustainable in the long run.
However, you have uncovered the unspoken problem of the electric car. The US currently consumes around 20M barrels of oil a day, which equates to some 11.3PWh of stored energy per year. In comparison, we only use roughly 4.3PWh in electricity per year. Now certainly electric vehicles and devices will be much more efficient than their fueled counterparts, but were still talking doubling our yearly electrical consumption.
The AC was referring to the fact that Gentoo just gives you the source, and makes you compile your own binaries. In effect, their 'packages' run on every arch, just with a bit of delay.
True. 5MB/s access speeds is painfully slow compared to the 100MB/s+ that linear tape and hard drives see. Presumably they will improve this before sending to market. There is no much use to a medium that takes 28 hours to fill.
How much does it cost to press 1000 DVDs for distribution to end users
Can you actually "press" holographic media? I thought the whole purpose of using holographs as proofs of authenticity was because they were difficult and expensive to produce.
No. What he's getting at is the market for a device like this is limited to people generating large volumes of data. Large volumes of data cannot be readily transferred across the internet on a consumer grade connection. People generating that large quantity of data are going to come up with their own storage solution (or purchase one to have on premises) rather than farm it out to some other company over the internet.
While I agree with you completely, you would only need relative cheap carousel loaders, not the big robotic loaders you see on tape archives. Sony makes a handful of them for DVDs that store between 200 and 400 disks, around a central reader.
Why not stick those on a shock mounted mobile hard drive? Your application doesn't seem like it needs the decades of media lifetime, or the costs it entails.

Yes, but that's not the point. He uses it, and he keeps using it repeatedly. Such behavior would indicate he has no idea what the unit actually means.
