It's got nothing to do with swine flu. You're running a fever. You're sick with something. Are you going to be the jackass who sits in a small, cramped aluminum tube for the next 5-15 hours, and risks infecting 300 of your closest friends with whatever you happen to have?
How about a more common scenario. One of your co-workers comes in coughing, sneezing, and lathers their arm in snot before leaning over your desk to see what you're looking at. Do you consider that acceptable behavior, or are you going to go to your boss to force them into taking a sick day and going home?
The thing is that Roadrunner can run programs that are not ridiculously parallel. Folding is split into discrete units that are computed and sent back up to months later. The units have absolutely no bearing on anything else running, and there is no need for intercommunication. If you had to perform some task that could not reasonably fit within the free resources of an idle computer, you're sunk. Sure, it has a huge amount of capacity, but you cannot compare it to something like the Roadrunner because it cannot, and was never intended to, perform the same sorts of tasks.
What's more, if Apple succeeds in making HD downloads seamless and reasonably fast with their new compression technologies, then it's game over for Blu-Ray.
Apple doesn't have any 'new compression technologies', they just use standard H264. Furthermore, they use CAVLC, which is about 30% less efficient than the more commonly used CABAC. At the moment, the best the iTunes store offers is relatively low bitrate 720p.
Most of the movies in my collection were never filmed in high definition, so the quality improvements in switching to Blu-ray would be minimal.
They were filmed in.... film, typically 35mm. 35mm is generally considered to be equivalent to 10-20MP depending on quality and age, with an upper limit somewhere around 25MP. Even after being clipped, cropped, spliced, edited, and composited with multiple layers and digital effects, a proper remaster should still be able to achieve at least 1920x800 (~1.5MP).
The only reason your collection wouldn't be able to be brought up to spec is because its full of low budget B movies, or you have a bunch of old movies that have degraded or been lost.
the former is not carrying the weight of the diesel engine + alternator
So what? You're talking a couple additional tons, compared to a couple thousand tons of cars and cargo. Hardly something to worry about. Add on the fact that rolling drag of iron wheels on iron track is extremely small, the only measurable loss would be from additional energy consumption during acceleration, and that can be recovered through regenerative breaking.
the former can do regenerative braking.
And the latter can't? In the end, they're both electric locomotives. Who's to say you can't just add a battery, or more likely a capacitor bank, to the diesel electric one. GE made a lot of noise in the press about five years ago, including several TV ads, when they started doing this in their Evolution line.
It did! But, there's really only so many times you can run through Mercy Hospital before the experience becomes a little dull. Unpredictable certainly(to a point). But the difference between meeting a witch on the roof verse the reception area is kind of moot by the 50th playthrough.
After the 50th playthrough (each of which takes 30-60 minutes depending on your team's skill level) of one map (out of four) of one playmode (out of two, or three if you include Survival), one could argue that you got your money's worth out of that game (especially if you got the $37.50 package deal or the $25 half-price deal).
Most users wouldn't understand the difference, flash or otherwise. The only incentive flash has at the moment is support for RTMPE. Content control is impossible on an open standard. You have to have control over the program to have control over the played content. If you can modify the code, or write your own program, you can simply ignore any copy restrictions. The only way around that is to have key revocation systems like BD+ where you can disable future access. Sites like Youtube or Dailymotion dont care, and there's no reason not to move to an open standard. Sites like Hulu will always use a closed module.
The article mentions a successful teleportation of a photon done during 1993. Now I know teleportation of quantum states is possible, and that there are attempts to use it as an advanced encryption scheme. However, this article seems to indicate real teleportation of physical matter has been achieved. Am I misinterpreting something, or are the CNN writers woefully misinformed?
Protein folding isn't the only HPC application. This card has as much memory as a Tesla, about 14% faster, and will likely cost considerably less. You can continue doing pharmaceutical gruntwork. The rest of us will run our own memory intensive applications.
The pulse is produced by gamma radiation impacting the atmosphere. On the ground, that means the generation of the pulse is very localized, and the dense atmosphere absorbs most of the pulse after a fairly short distance, making the affected area not much larger than the blast itself. With an orbital detonation, the pulse is generated over an area several hundred miles in diameter, and there is considerably less atmosphere to travel through.
Btw, NASCAR does this already on some tracks for safety reasons. You don't see any of those cars going 200+ mph. Even though they are completely capable of it.
Oh, but you do see them going 200+mph. What you don't see is them going 250+mph around a high banked turn and passing out. Instead, the cars end up grouping in large packs, and accidents take out several cars instead of just one or two.
Of course you can claim the big accidents are part of the spectacle of NASCAR. I know my little cousins sure get a kick out of them. One of them took popsicles down to the track after a race to trade with the cleanup crews for car parts.
Reading straight off the tech specs on the SmartUSA website, the lowest power fourtwo gets a whopping 33/41 estimated mpg. Add in a 0-60 speed of 12.8s, and its downright unsafe to try to enter the highway uphill or on a short ramp.
Why does everything need large battery banks? The idea is that you only have a bank large enough to get you up to speed, and then you cruise off the power from the generator. That about as much energy as my laptop battery contains. You wouldn't need a very large capacitor bank or flywheel to handle all your acceleration/breaking needs.
Your average car only needs some 15-20hp to travel at highway speeds. Even accounting for electrical efficiency losses, you're looking at around a single gallon of diesel. Now you have a mid-sized (3000lbs) sedan running 60+mpg. Considering most of the energy lost during breaking is recaptured, you don't significantly drop in economy during city driving.
What works on a big diesel-electric locomotive works just as well scaled down to a car. The only difference is that trains with hard metal wheels have negligable rolling resistance to deal with.
Different tech. Those were typically laser triangulation sensors (http://en.wikipedia.org/wiki/3D_scanner#Triangulation) where a line was beamed onto a rotating object and the profile gave the 3D shape. It allows accurate modeling of complex shapes, but is relatively slow and not particularly suited for this task.
Obviously cube farms can never go wireless due to density. There is no way, no how, you can simultaneously run hundreds of personnel at densities approaching one per square meter. Way too much interference.
Why not? 5GHz products have dozens of non-overlapping channels, as opposed to the 3 you get with 2.4GHz products.
With anachrome, you're basically SOL. With polarized filters, the theaters don't carry 2D glasses? We have a circular polarization setup at work for visualizing output from computer simulations, and we have a handful of glasses that are only clockwise (or counter, I can't remember) so you only get the one viewpoint.
From the same page, we get the alpheidae or 'pistol shrimp', whose snapping claws produce cavitation, sonoluminescence, and temperatures as high as 5000K. This generates sound levels as high as 218dB, or 190dB from 1m.
Linux is given access to 6 of the 7 SPEs, and the dual-execute PPE. IBM had poor yields when originally manufacturing such a large chip, so the Cell was designed with the capability deactivate parts of the hardware. IBM kept the fully functional chips for their blade servers, and ones with defects on only one of the SPEs were given to Sony for the PS3.
So wait a minute... You're complaining about Comcast dropping resolution and over compressing, so your solution is to download a lowered resolution and overly compressed copy online?

You forgot capacity.

Are you sure it was 3D (stereoscopic)? Disney World in Orlando has the same ride, but it's only 2D. No glasses used.
This is not a solar sail, this is aero-braking.

Yes, because only CompSci majors ever use intensive programs.
