Drive 350 miles between Montreal and Providence, and you'll pass through four states and one province. An extra 60 miles and you could add another two states to that. 7 states/provinces in 410 miles. Damn straight I've said aloud "What state are we in?" while driving in New England.
There are demos out there you can look at, using modified Rift HMDs. A company called SMI has been working on it. The limitation isn't the understanding of visual acuity, but the overall polish and sophistication of the implementation:
Another major issue is the ability to actually derive speed benefits from this approach. If you're implementing it by (as they do in this demo) rendering three different views at different resolutions in different passes, there's a fair bit of overhead involved, and I suspect that they'd also have overlap between the layers where they're rendering more than they need to (can you really tell a GPU to render a donut-shaped view and not spend any time on the pixels in the middle? I don't know, but I'm skeptical)
That, I think, is where nVidia's approach comes into play: by removing the performance penalty of rendering multiple projected views, and using the projection to get the detail (and lack thereof) where you want it to be, basically just a more extreme version of the lens-matched rendering that I linked the screenshots of. Refine that, refine the hardware to the point of being consumer-ready, and you start to see some major benefits.
Your eye can only really see detail in a very small area where you are directly looking (in the centre of your vision), but your brain is very good at filling in the blanks and hiding this fact. It drops off extremely rapidly, and for the vast majority of your field of view, you can resolve barely more than basic colour and movement.
The idea behind foveated rendering is, you use eye-tracking to figure out where the user's eye is looking, and then you render a very small full-detail image and place that where they're looking, and then you render a larger lower resolution image and put that behind it, repeating that until you're rendering very few pixels out around the periphery of the vision. Your eye can't tell that the image is getting less detailed (blurrier, really) as it moves away from your centre of vision, because you can't perceive the lack of detail. Obviously I'm simplifying with the progessively-lower-resolution-images description, but that's the gist of it.
When I say the detail drops off really fast from the centre of your vision, I mean it drops off EXTREMELY fast. Check out this graph:
Just 10 degrees off centre and you can only see 20% of the detail. But current rendering systems would still be drawing 100% of the pixels in that area.
To get an idea about how much processing power you can save with foveated rendering in an ideal case, basically consider the area of that graph overall (the whole square) versus just the area under the line. That's a speedup of multiple times.
I'll qualify all this with, I'm no expert, I've just read into it a bit.
Canada. Quebec, specifically. The specific text of the law in question (keeping mind this is in a section on employment contracts):
Either party to a contract for an indeterminate term may terminate it by giving notice of termination to the other party.
The notice of termination shall be given in reasonable time, taking into account, in particular, the nature of the employment, the specific circumstances in which it is carried on and the duration of the period of work.
It's required here, although technically it only applies to vacation time accrued according to the government mandated minimums, which max out at three weeks a year, and I believe it only counts for the prior and current years.
Either party to a contract for an indeterminate term may terminate it by giving notice of termination to the other party.
The notice of termination shall be given in reasonable time, taking into account, in particular, the nature of the employment, the specific circumstances in which it is carried on and the duration of the period of work.
There is also a more specific law specifically dealing with an employer terminating an employee, so essentially 2091 only applies to employee resignations.
The 2 weeks would be paid out normally because they're not vacation pay. You worked for those two weeks. When your employment ends, the employer is required to pay out any unused vacation time as a lump sum, which is a separate thing than payment for time worked.
That's unfortunate. There is a requirement here for both parties: the employee must give an unspecified amount of reasonable notice (generally understood to be two weeks, but basically what is reasonable depends on the nature of the work), and employers firing without cause must give notice that varies depending on how long the employee has worked there. It ranges from one week notice for less than a year of employment, to eight weeks for 10+ years of employment. If the employer provides less than the required amount of notice, they need to pay that missing time out as severance pay.
How IS it ray tracing? Modern VR requires a lens-correction distortion be performed after rendering so that the image you see through the lens matches what was rendered. Lens matched shading breaks the image up into four quadrants and renders four projected views that are a closer match to where the detail will be in the final result.
When a rendered scene normally goes through the distortion shader, most of the pixels around the edges are going to be lost as the distortion is strongest at the edges. This particular technique avoids that by starting out rendering less detail at the edges.
You could also take this to another level and use it for foveated rendering (where you render detail based on where the eye is looking), rather than the current technique of rendering multiple viewports at different resolutions and blending between them. Foveated rendering is a huge win for performance in that it results in a drastic reduction in pixels rendered, but the hardware (very accurate and very low latency eye tracking) and software required to do it isn't quite ready for consumer use.
I don't know about where you are, but here there employer gets to say when you're allowed to take vacation time, and you're required by law to give reasonable notice of resignation, which is generally understood to be two weeks. Employers are also required to pay out your vacation time when you quit. So you could give two weeks notice, and then after two weeks, you'd be done, and given ten weeks pay.
Labour laws vary, of course, but I can't imagine that there are places where employees can take vacation wherever you want. Even if you don't have a required notice of resignation period, you wouldn't be giving ten weeks notice, you'd be giving zero notice and then having your vacation time paid out...
In order to reach that figure, you had to narrow things down rather significantly. Not all aviation, only commercial aviation. Not all aircraft, only jets. Not all jets, only western ones.
There were 14 commercial aviation accidents in 2015. 8 of them did not involve fatalities on the commercial flight (one did involve fatalities on the other aircraft in a collision), 2 of them were intentional (copilot suicide, terrorist bombing), and the other 6 were either turboprops or non-western aircraft.
All told, 525 people were killed in accidents involving commercial aviation in 2015. It's still a very tiny percentage of everybody who flew, but cherry-picking to pretend it was zero isn't right.

What? The monitors did what they were supposed to do, are doing what they were supposed to do, and will keep on doing the same thing they were supposed to do. It's also entirely possible that they will work with thunderbolt 3 via an adapter.
They also stayed on the market for 5 years, which is unheard of for a modern display: most companies like Dell discontinue their displays after a year or two.
Mail delivery was already reduced to three days a week, before they stopped door to door delivery altogether. Undoing that was an election promise of the current government.
As opposed to community mailboxes that have a tendency to freeze shut? People had taken to using lighters and spray bottles of antifreeze to get their mail.
This is not the first laptop to ship with an OLED screen. Lenovo has been shipping one for a few months, and HP announced one, although I'm not sure if it's shipping yet.
> Your Tesla vehicle is protected by a 4 year, 50,000 miles (whichever comes first) new vehicle limited warranty
70,000 miles is out of warranty. They do offer an extended warranty to double both those (for, it appears, $4,000), but obviously that wasn't purchased in this case.
Because he didn't do it right away, he'd wait until the streamers had spent the money, and then try to issue the refund with PayPal, which would then cause PayPal to charge the streamer back for the money. In essence, he was putting the streamers in debt.
Really, he ought to go to jail for that, but at least in this case he got stiffed.
For varying definitions of "supported". Hasn't development of the old ZFS been at a standstill apart from critical patches, while OpenZFS has continued to evolve?
When every other provider on the market was offering cheap storage (including Google and Microsoft), Dropbox refused to drop their prices. They were charging for 100GB what everybody else was charging for 1TB. As such, they lost a lot of customers to the competition, and a lot of customers who could have been producing revenue stuck with the "free" tier rather than pay $10 a month.
They've sort of learned their lesson, now offering 1TB for $10/mth, but still haven't quite caught on yet: they don't have anything between $0 and $10 a month. A lot of customers who want a bit more than the free tier, but don't want to pay $10/mth, aren't being served. Google will sell you 100GB for $2/mth, and I bet Dropbox is leaving a lot of money on the table by forcing people to pick between Google at $2 or DropBox at $10.
Possibly, but I think there are three possible outcomes:
1) Tesla's valuation changes to resemble that of an automotive company instead of a technology company by dropping sharply in the near-future 2) Tesla's valuation changes to resemble that of an automotive company instead of a technology company by remaining static while their sales catch up to what a car company at that valuation would be expected to produce 3) Tesla's valuation continues to be that of a technology company, and continues to grow with sales.
I think that reality will be somewhere between 2 and 3.
More than that, could Ford even afford to buy Tesla? They're similarly sized companies by value, and Tesla's market cap will probably rise as the Model 3 ramps up. Musk also owns a decent chunk of Tesla: he's increased his share of the company from 22% to 27% over the past few years by buying additional stock.
> My guess is that 99% of tourists that are dumb enough to give up their fingerprints and financial information to a foreign government will be carrying a wallet, anyway.
Fingerprints are mandatory for all tourists who enter Japan already. Lots of people who enter the US too. Are you suggesting that tourists should simply stop visiting Japan entirely?

I'm afraid Western Australia has me beat, because most of the cities in Quebec that are furthest away are not accessible by road, only by air :)

I'd argue that either case was a dick move, but there would still be some legal differences in terms of when certain benefits end.

Not to mention that the 480 is NOT in the same price class as the 970
The 8GB 480 is $239, while the 970 starts at $259. I'd say that's the same price class.
