North Korea Denies Responsibility for Sony Attack, Warns Against Retaliation

reve_etrange Re:of course it wasn't NK (142 comments)

It would have been in some theaters, but not the two largest chains. The movie industry has a number of rules / conventions (some contractual) pertaining to theatrical releases, so Sony decided to try again later instead of just release in some theaters.

They easily could have released already via another distribution channel (such as their own streaming service, Crackle), but they are probably still hoping for a high-gross opening weekend in theaters, which they will no doubt get after all the publicity the film's received.

Anyway, I do wonder if the hackers just meant that the movie is so terrible, theater goers will want to blow themselves up.

North Korea Denies Responsibility for Sony Attack, Warns Against Retaliation

reve_etrange Re:of course it wasn't NK (142 comments)

And now Sony is know for having no spine.

Really, it's Regal Cinemas that's spineless. Sony didn't have much choice once so many theaters pulled out - but they're still whack for hoping no one remembers they own Crackle

No worries, I had to read it a few times too - the claim is so outlandish.

Quantum Physics Just Got Less Complicated

reve_etrange Re:Not News (182 comments)

The quote I used comes at the conclusion of a mathematical demonstration - here's the link. I've now had the time to read the new paper (TFA), and they actually credit Feynman right at the start for having the general insight. Feynman's discussion is for a single uncertainty relation (position and momentum for a "particle" composed of a finite wave train), while TFA is broadly general and cached in terms of the modern entropy-based approached to uncertainty. So I think you're right, in that Feynman's treatment can't really be called a "framework" - it only deals with a single problem.

Really the only problem here is gross overstatement in TFS...but what else is new.

Quantum Physics Just Got Less Complicated

reve_etrange Re:Lame (182 comments)

Maybe you're thinking of The Feynman Lectures (which is college-level)? In Volume 3, Section 2-2 of his lectures, Feynman shows the deep relationship between the uncertainty principle and wave-particle duality. Feynman sez:

Now this property of waves, that the length of the wave train times the uncertainty of the wave number associated with it is at least 2, is a property that is known to everyone who studies them.

the rigorous mathematical framework

Like the one shown in Volume 3, Section 2-2 of the Feynman Lectures of Physics, published 1964?

Now this property of waves, that the length of the wave train times the uncertainty of the wave number associated with it is at least 2, is a property that is known to everyone who studies them. It has nothing to do with quantum mechanics. It is simply that if we have a finite train, we cannot count the waves in it very precisely.

FBI Confirms Open Investigation Into Gamergate

Parent wrote:

There's a big difference to a general attack on women because of their sex and criticisms towards specific women for their actions, which the anti-gamergate side refuses to acknowledge. The former may or may not be misogyny (depends on the motive for the generalization)

The "former" applies directly to the phrase "a general attack on women because of their sex" (emphasis mine). The elided part of the sentence has no bearing on this fact.

Criticizing someone who happens to be female for things that have nothing to do with her being a female could be misogyny, but is not guaranteed to be misogyny.

The parent specifically refers to a "attack on women because of their sex," which explicitly has to do with their being female. The parent doesn't say "criticizing...for things that have nothing to do with being female," it says "attacks...because of their [female] sex." Hope that clears things up for you.

Actually, that is pretty much the definition of misogyny.

"Team America" Gets Post-Hack Yanking At Alamo Drafthouse, Too

reve_etrange Re: America! (227 comments)

It is probably just a viral marketing campaign by Sony.

The sad thing is, it would actually be better that way.

Critical Git Security Vulnerability Announced

reve_etrange Re:Unrelated to Github (145 comments)

All modern systems are capable of storing different strings for filenames in different cases

Including Windows (with NTFS) - but the API used to access the filesystem normalizes everything. It leads to a lot of weird behavior...

Critical Git Security Vulnerability Announced

reve_etrange Re:I blame Microsoft (145 comments)

One pet peeve of mine is people creating file names like: "this is a book of my whole life and everything i know.doc'" drives me crazy :)

You can definitely blame Microsoft for that one (default Word filename is first line of document).

Research Highlights How AI Sees and How It Knows What It's Looking At

reve_etrange Re:Automatic cars are just around the corner... (125 comments)

I guess the price goes a long way towards showing how much more impressive the computer vision approach would be, if it worked. A (stereoscopic) camera produces much less information than LIDAR, and visual tasks are always deceptively complex.

NASA Study Proposes Airships, Cloud Cities For Venus Exploration

reve_etrange Re:Solar irradiance in the article? (198 comments)

My bad, I thought you wrote "inverse-square" the second time. The irradiance depends on the latitude and declination as well as the distance from the sun - I found this site with detailed formulae. Basically in addition to the inverse-square factor is a sinusodial factor for the angle and a logarithmic factor for the atmospheric absorption, but it turns out the inverse-square part really is dominant for the average values at the top of the atmosphere, just like your intution. These data also support that.

They might not be referring to top-of-atmosphere values, though, so there's no way to tell if they're actually mistaken without knowing what atmospheric heights they're comparing. The atmospheric effect is surprisingly large even on Mars, where the attenuation is at least 1.2-fold and as high as 150-fold during a storm (from the Viking data from the first link).

So you admit you have no arguments, but only trivial reversals of any proposition, which you then regard as authoritative.

reve_etrange Re:Automatic cars are just around the corner... (125 comments)

It's reassuring that the decision-makers in that process consider alternative ideas; basing the goal on 'human-like' sight would leave a lot of room for error

It's true, but using 3D laser mapping feels a little bit like cheating - after all, human drivers don't need nearly that much information. A successful computer vision approach would be a lot more impressive, even if it was too dangerous for the highway.

You better hope your car is not just taking one single still image and performing actions based on that.

In fact, most of them don't use computer vision much at all. Google's self-driving car for example uses a rotating IR laser to directly measure its surrounds.
