You don't have to use metro, you know. Click the little desktop tile when you first login, or use one of the metro bypassers like start8 (even puts the start button back). Not sure why anyone would miss the start button though. Something like Launchy for pre windows 7, or just start typing after hitting a button for windows 7 and on. I suppose if you're a non-keyboard user user, it almost makes sense.
>The problem is keeping the "car" stably in contact with the ground.
If the thrust is around 30,000 lbs, and you point only 1% of that the wrong way, you have to come up with 300lb of force to keep the car going straight, on a dirt road...better be quick, because you're going 1000mph!
Crazy!
I would love to see the track marks after the run. I'm guessing there's all sorts of sliding around.
When you stick your device into the desktop dock, it's a desktop, using an external graphics accelerator, mass storage, network, mouse, etc. When you pull it off of the dock (that isn't bound by one manufacturer)....
... it's a laptop with touchscreen. The keyboard is removable, maybe with some extra flash memory and battery built in. When you pull off the keyboard...
... it's a tablet, as you would expect.
But, *all of the software* is aware of the docking state. If you pull off the keyboard, the touchpad keyboard pops up when needed. The UI expands to be less "consumption" oriented use. When you attach it to the desktop, the UI changes and expands into more of a "developer mode" to accommodate a mouse and the extra horsepower built into the desktop dock.
Of course, this wont happen because it's not what people want...but it sure would be nice.:(
Here here good Sir! You're not suggesting that he had some sort of privileged access to the thread before anyone else!? That would require an inside man, and we all know that the Slashdot editing staff would never allow such a thing! Surely you jest!
If my screen cold fold back or rotate around, I would be all for this. Otherwise, no...your laptop ends up being across the table, and most computer desks are too short in these days of flat screens.
My last laptop screen had brackets that fit either way and it lived with the screen backwards just for this reason.
...but I definitely have a fear of consuming or inhaling anything nano-particle based. But, I also think it's insane that we have no long term medical studies...of anything really.
I'd agree, but this would have to be something to do with infrared, otherwise it wouldn't work in the evening. I have trouble believing much information would be present in an infrared-only illuminated hand, although, the numbers they quote could be best case (well lit room with wrinkle hands).
In other news, in a Slashdot interview with Slashdot user "anonymous coward", "anonymous coward" claims to be the most powerful and intelligent user, in the world.
Well, anything that can reasonably power a > 3000lb car up a freeway hill will be much more than 200lbs. Why not put a weed eater engine in, then your numbers will look way more impressive.
You misunderstand. I don't claim that it's not possible, since the incident report link to in TFA say that it is plenty capable of boiling skin off. I'm saying, I don't believe the numbers the journalist claim were the at-his-flesh numbers.
Hrmm, doing the math, I'm not sure I can believe it. I'm still guessing that's the power at the transmitter and he was being a normal reporter, claiming the biggest numbers.
Assuming 1/32 penetration depth (95Ghz is more like 1/64), only 50% absorbtion (95GHz on forearm is around 70%), and he was made 100% out of water (best case scenario for maximum specific heat, and he might be a little sweaty) that's something like a 76 degree rise in temperature per second...I call reporter reporting big numbers type of bullshit.
No, it's not 12 joules per second per cm^2 over the whole path. And no, you wont ever get hit by the thing being close enough to make that true. Damn inverse square laws, right?
I think you should review the maths for a corner reflectors. In angle = out angle for, basically, the whole 90 degree opening, with a slight radial offset perpendicular with the beams direction. The most work would be figuring out which maybe 70 usable degrees segment to point the thing. With the size of it, and the fact that it requires line of site, do you really see this as a daunting task? Hey, tape two together! Now you have nearly 180 degrees! And, this isn't a laser beam...it spreads...you don't have to aim it precisely, and that would be the biggest problem! If it only works to 700m, you would have to be no more than 700m/2 for them to feel anything, and they'll always feel much less than half the pain of anyone around you.
Grounding is unnecessary for reflecting something a few wavelengths larger than the frequency of interest. At 3mm, you'd be completely safe, and fairly dangerous, behind a sheet of tinfoil.
Grounding is 100% unnecessary for a Faraday cage. RF doesn't know or care what ground is...all it can see is changes in impedance.

Depends on your cost metric. They're only cheaper if you don't consider cost per computation/second.

I wonder what percent of power goes to downforce.
In the future I see a harmonized ui.

They'll just implement a "random wobble" algorithm after the first is found.
How do they measure the distance of something like this?

Speckle interferometry? Mid infrared laser with a piezo shift mirror and a decent resolution ccd?

This is the original image. You're free to do as many lossy operations on it as your heart desires.

Geiger counters tell you if there's radiation at the counters sensor. This lets you measure/see where the radiation is coming from.
Series hybrid are much more efficient than parallel hybrid since you can have a relatively small motor that continuously runs at peak efficiency: http://serieshybrid.com/FreedomFormula/images/Drivetrain_Comparison.pdf

It'll dissipate? If only I mentioned that in the last two sentences.
