Show me another summer tent-pole film being shot in 3D. Are theaters expected to break even on their hardware investment from their take on one film? Unlikely. Where's the commitment from studios to 3D? Theaters need a future lineup of films that utilize the new projectors to justify such an expense. Also there is mixed work of mouth on viewer reaction to 3D, so that ups the gamble for early adopters who might be buying the next Edsel.
That is a terrible misconception, it will be 'awful and distracting' only because you got used to films looking like films at 24fps and 'home video' having smoother motion.
You say "only because", but it's a big hurdle to surmount. There may not be any sense to it, but these are the conventions we've been living with for past X years, and I think it'll take a long time before we (as a whole) get used to it. 24fps=Drama, 60fps=News and infomercials.
It's only jittery because action movies have come out of the Private Ryan/Gladiator school of film making for the last 15 years or so. Read more here: http://en.wikipedia.org/wiki/Rotary_disc_shutter [wikipedia.org]
It's nothing to do with the rotary disc shutter, per se - the "traditional motion blur" movies you mention use them too. From the wiki-page:
Using an "Exposure Time" of 1/50 sec. we get a "Shutter Angle" value of 173, very close to 180 (normal motion blur effect).
There aren't huge problems - there's a simple, conventional way of doing it, though it admittedly does result in an irregular judder (as opposed to a regular one) when watching on a CRT screen. Modern LCDs, though (those that are worth their salt) should be capable of matching this cadence and automatically undoing it.
PAL DVDs run at 25fps, which is a better match for the 50fps Euro CRTs)
I'm expecting them to have shot at around 1/96. It's my experience that matching the shutter speed to the frame rate results in too much (perceptually speaking) motion blur, no matter what the frame rate.
In a past life I did some CGI work for a couple of ads running at 50fps, and a simulated 1/50 shutter speed looked horribly blurry. 1/100 was just right.
Which would then give you enough space to triple the resolution (which may be what the GGP was driving at) or, if not, would increase sharpness in any case. As demonstrated by the effectiveness of Cleartype, RGB subsampling does have an impact on perceived resolution, and RGB subpixel techniques can be applied to colour images as well as text.
Weird, I must have said something relevant to your point in alternate universe, rather than just picking on your grammar:)
But anyway, now that I've broken the rules and read the article, it sounds like most uses they plan on putting this to will be for people who have already suffered spinal damage. Those of us who just want to program the TIVO with their minds will just have to wait.
You really don't want to mess with that.
The MIT guys (and it might be safe to assume they have at least one medical degree between them) seem to think differently.
Or perhaps he's more than capable, but is trying to make a point about the assumptions that Slashdot summary writers often make. All it would take is prefacing her name with "pioneering aviator", or similar (you know, like real journalists do, all the time), and everyone's instantly much better informed at the cost of two words.
The Nicest Guy At the World's Largest Weapons Expo
If you want to publicise the work of some actual nice guys, what about those people who go into warzones simply to provide this kind of facility (some even do it for free, the gall of these people!) to those who are suffering because they happen to live in the middle of a war they want no part in?
Do you really think anyone would want to steal that?
Do you really think no-one would? What if there's a vulnerability in there that could send the entire tumbling down? I'm sure no foreign power would be interested in that.
The calculation in the study required 54 million processor hours on the IBM BlueGene/P supercomputer at Argonne National Laboratory, the equivalent of 281 days of computing with 8,000 processors.
But what's that in rods per hogshead? Or is "8,000 processors" some kind of conventional metric for processing?
The use of an UAV for stockpile monitoring sounds like a bit of hype to me. Stockpiles are constantly changing not only in size, but in shape as well. Hence, they need to be constantly monitored. Show me an UAV that can constantly monitor a stockpile in real time 24/7, then we'll talk.
Maybe there are plenty of stockpiles around the world that don't need to be monitored every minute of every day.
I should read the article because the headline doesn't relate to the summary? Not sure what your logic is there.
A headline should be to a summary as a summary is to an article.
Van Jacobson Denies Averting Internet Meltdown In 1980s
And then we have the summary, which appears to recount a not particularly exciting anecdote about how a guy noticed things were going a bit slower than they should for an indeterminate amount of time and with indeterminate consequences. It doesn't even tell us what Van Jacobson did do when he wasn't averting a mythical meltdown.
Slashdot Mirror
I think James Cameron is pushing the more home-friendly 60fps.
Blu-ray can do 1080i@60 though. Resolution is only 50%, but perceptually it's more like 70% (or more, given the decent deinterlacers in modern TVs).

I could agree more. It literally makes my blood boil!

I'd just assume not f' with that.
Oh great, is this the next "I could care less"?

Seriously, how can someone be so stupid?
I believe you meant "uninformed."
By the very act of asking the question, the GP is demonstrably not what I would call "stupid."
Do they have an education system in your country? Internet? books?
A rather presumptuous implication, given that all you know is that the GP doesn't know one fact from the history of one country.
no alien signals were detected. This result isn't surprising

Even though this story has been blowing-up on Twitter, there are a few caveats
Even though? Really? Because normally Twitter is the most trustworthy news source?
Why is it so hard for people to prefix their own opinions (however widely-shared they may be) with "I think..."?
