Comment Re:Google Cardboard (Score 1) 198

Turning it on its side and putting it into the Google Cardboard (or similar) stereoptic holder gives you about a 1440x1250 display per eye. Looks right to me.

Now if (as I suggested in the Cardboard item) they installed two cameras on the phone back, separated by about eye distance, you'd have a camera that could take and display stereoptic pictures and/or do augmented reality without losing the scene's depth.

Comment Retina display and dual cameras... (Score 4, Interesting) 42

This is a great use for the (otherwise excessively) high-resolution cellphone displays such as Apple's "retina".

Also: This is a strong argument for putting TWO cameras on a cellphone's backside - separated by about the typical distance between a person's eyes and equally speced relative to the centerline of the phone. That would enable the formation of a stereoscopic augmented reality display showing the correct image of the background. (It would also enable taking stereoptic pictures.)

Comment Able to grow crops now grown a bit farther south. (Score 0) 567

Even some of the more extreme estimates of the amount of temperature change expected just mean, to a farmer, that his great grandsons might do better if they switch to crops that are currently grown a couple hundred miles closer to the equator or a couple hundred feet lower on the hillside. (Something like they did during the Medieval Warm Period, when Iceland had lots more cropland and grapes were grown on a large scale in Britain.)

So even if you convince them that global warming is real, don't expect anything but a cheer from the farmers of Sweden.

There are a lot of steps between "It looks like the average temperature might go up four or five degrees C in the next couple centuries." to "We must take drastic action RIGHT NOW to AVERT DISASTER!". Like figuring out whether such a temperature rise is really a threat - or might even be a boon. We're still working on "Is it real?"

Except, of course, for politicians, who can use that last claim to increase their power, or (like Al Gore) make billions off a "carbon credit exchange" built on anti-global-warming legislation.

The last thing I need, if I'm injured in a way that disfigures my face, is a car that won't let me start it to drive to the emergency room.

That's right up there with the federal experiment, back in the '60s or so, with mandating seatbelt and seat weight sensors that interlocked with the starter, so you can't start it if all the passengers aren't belted in.

(I, and about five of my friends, were very luck my car dated from before that mandate, the time we were visiting a friend who worked in a trainyard, my car stalled across a track, a train came {slowly but inexorably} around the sharp curve, and my right-front passenger unbelted in preparation to bail if I couldn't get it going again. We didn't have enough time to all bail ...)

Comment Privacy? In The Cloud? (Score 1) 214

So apple is retiring a photo editing software product and expects their customers to switch to their cloud photo editing service. They're replacing images stored locally with images stored externally.

Ignoring Snowden and the NSA for the moment, let's look at LEGAL seizure of your pictures to be used as evidence by government agencies, in rule enforcement, investigation, and criminal prosecution.

Not only are files under your physical control y'harder to get to physically than those transmitted over the Internet and stored in a vendor's server farm, they're also on better legal ground. The Supreme Court seems bent on treating electronic files, under your control, just like paper files locked in a safe at home. Just three days ago they ruled that police can't even search information stored on a cellpone carried by an arrestee without first coming up with probable cause and obtaining a warrant.

The last I heard, though, they considered information you stored on some vendor's servers to have been disclosed - that you have "no expectation of privacy" with respect to it. The police can go fishing through it just by asking, without jepoardizing prosecutions that result from what they fiind. Even if the third party cloud service demands paperwork rather than just giving access, a company like Apple has far less interest in protecting your data from fishing expeditions than you do.

Given the rat's nest of laws in the US, the prevalance of false or mistaken prosecutions, and the deliberate use of the legal and tax systems to punish those disliked by those in power (at all levels), I'd think nio sane person would put any personal information onto a cloud service (without at least encrypting it locally first with a key unknown to the service), let alone in a form that could be manipulated on the service. Photos are a particular risk, for a number of reasons I don't think I need to enumerate.

So I'd think that, both for personal use and for professional photographers, the substitution of a cloud service for a local tool working on locally stored data, would be unacceptable.

So basically, if they just shift from LIVE to a TIME DELAYED model, they could go right on transmitting and not be considered "performing" under the current act.

As J. Scalia points out, the 'standard' the Court has chosen is unclear. Maybe that would be legal, maybe it wouldn't be. We'll never know until either 1) Congress amends the law to be clear about that; 2) Someone tries it and the Court reverses this opinion in a useful way; or 3) Someone tries it and the Court rules squarely on that in light of this opinion.

One thing is for sure: Only someone with lots of resources and a lot of daring will even attempt to find out by actually trying it.

Comment The key distinction in the ruling (Score 5, Informative) 484

This case boiled down to one major issue: Whether the allegedly infringing conduct in this case was engaged in by either Aereo, or by its users. Don't get hung up on the public performance v. private performance issue; it was really certain that if Aereo was liable, that the performance was public; if it were the users, it would be private.

J. Scalia's dissent does a good job of explaining the issue:

There are two types of liability for copyright infringement: direct and secondary. As its name suggests, the former applies when an actor personally engages in infringing conduct. Secondary liability, by contrast, is a means of holding defendants responsible for infringement by third parties, even when the defendants âoehave not themselves engaged in the infringing activity.â It applies when a defendant âoeintentionally induc[es] or encourag[es]â infringing acts by others or profits from such acts âoewhile declining to exer- cise a right to stop or limit [them].â

Most suits against equipment manufacturers and service providers involve secondary-liability claims. For example, when movie studios sued to block the sale of Sonyâ(TM)s Betamax videocassette recorder (VCR), they argued that Sony was liable because its customers were making unauthorized copies. Record labels and movie studios relied on a similar theory when they sued Grokster and StreamCast, two providers of peer-to-peer file-sharing software.

This suit, or rather the portion of it before us here, is fundamentally different. The Networks claim that Aereo directly infringes their public-performance right. Accordingly, the Networks must prove that Aereo âoeperform[s]â copyrighted works, Â106(4), when its subscribers log in, select a channel, and push the âoewatchâ button. That process undoubtedly results in a performance; the question is who does the performing. If Aereoâ(TM)s subscribers perform but Aereo does not, the claim necessarily fails.
The Networksâ(TM) claim is governed by a simple but profoundly important rule: A defendant may be held directly liable only if it has engaged in volitional conduct that violates the Act. ...

A comparison between copy shops and video-on-demand services illustrates the point. A copy shop rents out photocopiers on a per-use basis. One customer might copy his 10-year-oldâ(TM)s drawingsâ"a perfectly lawful thing to doâ" while another might duplicate a famous artistâ(TM)s copyrighted photographsâ"a use clearly prohibited by Â106(1). Either way, the customer chooses the content and activates the copying function; the photocopier does nothing except in response to the customerâ(TM)s commands. Because the shop plays no role in selecting the content, it cannot be held directly liable when a customer makes an infringing copy.

Video-on-demand services, like photocopiers, respond automatically to user input, but they differ in one crucial respect: They choose the content. When a user signs in to Netflix, for example, âoethousands of . . . movies [and] TV episodesâ carefully curated by Netflix are âoeavailable to watch instantly.â That selection and arrangement by the service provider constitutes a volitional act directed to specific copyrighted works and thus serves as a basis for direct liability.

The distinction between direct and secondary liability would collapse if there were not a clear rule for determining whether the defendant committed the infringing act. The volitional-conduct requirement supplies that rule; its purpose is not to excuse defendants from accountability, but to channel the claims against them into the correct analytical track. Thus, in the example given above, the fact that the copy shop does not choose the content simply means that its culpability will be assessed using secondary-liability rules rather than direct-liability rules.

So which is Aereo: the copy shop or the video-on-demand service? In truth, it is neither. Rather, it is akin to a copy shop that provides its patrons with a library card. Aereo offers access to an automated system consisting of routers, servers, transcoders, and dime-sized antennae. Like a photocopier or VCR, that system lies dormant until a subscriber activates it. When a subscriber selects a pro- gram, Aereoâ(TM)s system picks up the relevant broadcast signal, translates its audio and video components into digital data, stores the data in a user-specific file, and transmits that fileâ(TM)s contents to the subscriber via the Internetâ"at which point the subscriberâ(TM)s laptop, tablet, or other device displays the broadcast just as an ordinary television would. ...

The only question is whether those performances are the product of Aereoâ(TM)s volitional conduct.

They are not. Unlike video-on-demand services, Aereo does not provide a prearranged assortment of movies and television shows. Rather, it assigns each subscriber an antenna thatâ"like a library cardâ"can be used to obtain whatever broadcasts are freely available. Some of those broadcasts are copyrighted; others are in the public do- main. The key point is that subscribers call all the shots: Aereoâ(TM)s automated system does not relay any program, copyrighted or not, until a subscriber selects the program and tells Aereo to relay it. Aereoâ(TM)s operation of that system is a volitional act and a but-for cause of the resulting performances, but, as in the case of the copy shop, that degree of involvement is not enough for direct liability.

In sum, Aereo does not âoeperformâ for the sole and simple reason that it does not make the choice of content. And because Aereo does not perform, it cannot be held directly liable for infringing the Networksâ(TM) public-performance right.

However, that's not the decision that the Court reached. Instead, J. Scalia describes the Court's opinion as:

The Courtâ(TM)s conclusion that Aereo performs boils down to the following syllogism: (1) Congress amended the Act to overrule our decisions holding that cable systems do not perform when they retransmit over-the-air broadcasts;4 (2) Aereo looks a lot like a cable system; therefore (3) Aereo performs. ...

Making matters worse, the Court provides no criteria for determining when its cable-TV-lookalike rule applies. Must a defendant offer access to live television to qualify? If similarity to cable-television service is the measure, then the answer must be yes. But consider the implications of that answer: Aereo would be free to do exactly what it is doing right now so long as it built mandatory time shifting into its âoewatchâ function. Aereo would not be providing live television if it made subscribers wait to tune in until after a showâ(TM)s live broadcast ended. A subscriber could watch the 7 p.m. airing of a 1-hour program any time after 8 p.m. Assuming the Court does not intend to adopt such a do-nothing rule (though it very well may), there must be some other means of identifying who is and is not subject to its guilt-by-resemblance regime.

Two other criteria come to mind. One would cover any automated service that captures and stores live television broadcasts at a userâ(TM)s direction. That canâ(TM)t be right, since it is exactly what remote storage digital video recorders (RSâ"DVRs) do, and the Court insists that its âoelimited holdingâ does not decide the fate of those devices. The other potential benchmark is the one offered by the Gov- ernment: The cable-TV-lookalike rule embraces any entity that âoeoperates an integrated system, substantially dependent on physical equipment that is used in common by [its] subscribers.â The Court sensibly avoids that approach because it would sweep in Internet service providers and a host of other entities that quite obviously do not perform.
That leaves as the criterion of cable-TV-resemblance nothing but thâ(TM)olâ(TM) totality-of-the-circumstances test (which is not a test at all but merely assertion of an intent to perform test-free, ad hoc, case-by-case evaluation). It will take years, perhaps decades, to determine which automated systems now in existence are governed by the traditional volitional-conduct test and which get the Aereo treatment. (And automated systems now in contemplation will have to take their chances.)

The Court's opinion states that it doesn't have an effect beyond Aereo and Aereo-like services:

Aereo and many of its supporting amici argue that to apply the Transmit Clause to Aereoâ(TM)s conduct will impose copyright liability on other technologies, including new technologies, that Congress could not possibly have wanted to reach. We agree that Congress, while intending the Transmit Clause to apply broadly to cable companies and their equivalents, did not intend to discourage or to control the emergence or use of different kinds of technologies. But we do not believe that our limited holding today will have that effect.

For one thing, the history of cable broadcast transmis- sions that led to the enactment of the Transmit Clause informs our conclusion that Aereo âoeperform[s],â but it does not determine whether different kinds of providers in different contexts also âoeperform.â For another, an entity only transmits a performance when it communicates contemporaneously perceptible images and sounds of a work. ...

And we have not considered whether the public performance right is infringed when the user of a service pays primarily for something other than the transmission of copyrighted works, such as the remote storage of content.

But, as J. Scalia points out:

The Court vows that its ruling will not affect cloud-storage providers and cable- television systems, but it cannot deliver on that promise given the imprecision of its result-driven rule.

Photons need to have gamma-ray energies before they can create virtual electro-positron pairs. Visible light simply does not have enough energy to do this.

No, they don't

They need those energies to create REAL, PERSISTENT electron-positron pairs, which fly away and last until they interact with something else - maybe centuries or eons later - that changes them to some other particle.

Virtual particle pairs, as long as their lifetime is less than a time that puts the product of the "error' in energy with the lifetime of the error under the uncertainty principle limit, can be created by photons that are far too small to create free particles. In fact, if the lifetime of the virtual particle pair is short enough, you don't even need the photon.
