Of course, some people/corporations will make arguments relating internet to delivery services -- paying more for overnight shipping means you get the package/letter faster. Of course, this is a flawed argument for myriad reasons, not the least of which is that if someone mails me an overnight letter I don't then have to pay extra to receive it...
Good point. I think, though, that they approached it completely backwards: they have presented a method for determining the information-theory voxel size of the universe (or whatever you like to call it), NOT the energy density, as TFS claims. That is, I think they should have started with the correct answer (10^-27 g/cm^3) and derived the voxel size from there. Then we could debate on the physical meaning of this voxel, which is a legitimate thing to talk about.
No, I think this information theory "approach" uses 10km^3 voxels:
Specifying the location of the 10^25 stars in the visible universe to an accuracy of 10 cubic kilometers...gives an energy density of about 10^-30 g/cm^3....But if the location has to be specified to the Planck length, then the energy density is about 117 orders of magnitude larger.
So they roughly recover the quantum mechanical (apparently incorrect) result if they use Planck length^3 voxels.
Not that I read the article of course, but this seems an odd thing to do, as you should probably be confining them to hbar units of phase-space, not just confining them to voxels.
It boils down to solid angle per pixel -- sit close enough to a huge screen and you'll be able to tell the difference.
I could imagine absolutely humongous curved screens being really cool -- the periphery might not contain any information relevant to the plot of the movie, but it would make for a very immersive experience. I call it the 4pi steradian display...
This is sort of true for home audio as well -- surround sound receivers are cheap. Surround-sound preamps, though, tend to be very pricey, even though a very basic preamp would just be the receiver sans the final amplification.
Interesting -- that does seem surprisingly small. Had to check it out myself:) looks like each server is drawing a little over 100W, which seems more-or-less reasonable: http://www.wolframalpha.com/in...
Yeah, there is some cool work being done on thermal energy storage, particularly with molten salt (industrial level): http://en.wikipedia.org/wiki/T...
At the in-home level, who knows, maybe a rack of batteries will become as commonplace as a water heater.
Solar's production curve does not match the peak user curve of electrical power.
Although I think in some places (e.g., Los Angeles) it does match fairly well, as air conditioners use a lot of juice. But I completely agree: nuclear is a terrible form of energy...but it's better than most alternatives.
I have a C1, and it's pretty neat. However, the software support just isn't there -- I would like to replace my RPi as a media center, but the C1 currently can't decode MPEG2 (wat?), DTS-HD MA passthrough didn't work last I checked, and HDMI-CEC doesn't work either (again, last I checked -- about a week ago). VC-1 only recently started working (despite the website clearly indicating that it works...).
That said, dedicated gigabit ethernet is great -- even if it doesn't quite the performance you'd expect from gigE, it's still a lot better than the RPi (and it's not sharing USB bandwidth, so that's a huge plus too).
Though I suspect this mandated noise will be very different from the faux muscle car roar. Longer wavelength sounds are harder to localize, which makes much of the deep growl of a V8 -- real or simulated -- less useful than, say, the backup beep of a large truck.
Yeah, sounds cumbersome. That said, there are the rather slick looking super thin HDMI cables: http://www.monoprice.com/Produ... (no affiliation to monoprice, just like their stuff)
That said, is there a power-over-HDMI spec, or does it need a separate cord, too?
Sadly, it doesn't look like it has a TrackPoint-style mouse -- something I've grown rather fond of (just to preempt the oblig replies: http://xkcd.com/243/).

...imposes 2000s (1990s?) Internet access speed!
People always misuse that word. I think you mean, "infected" ;)
Although, in fairness, adding loads of printk(KERN_WARNING "Hire Dave! He's really qualified!\n"); was a pretty great feature.

If you're starting with the location of stars, that's hardly a first principles calculation...?
I think the question was about refresh rates, hence the comment that other articles claim 60Hz (@ 8k).

Cool stuff!
Exactly how many nuclear disasters does it take before we figure out how to do what these other countries are already doing?
Nuclear energy is just about the safest form of energy: http://www.forbes.com/sites/ja...
Energy is really, really dangerous, end of story. Nuclear is somehow the "scariest," but not because it's statistically more dangerous.

I'll be "that other...other guy" and point out that LEGO is still all-caps.
Sounds like some sort of euphemism...
Out of curiosity, do you know if The Interview is available in most/all regions?
I subscribe to and love Netflix here in the USA, but I've heard that in other countries it can have a rather anemic assortment of content...

You should be modded +5 insightful-yet-depressing ;)
I think they mean "GNU/Linux," as Chrome OS runs the Linux kernel.
I don't think I'm brave enough to ask what the Wankel analogy would be...
