OK, I think I'm missing something. To quote the article:

> And no, you can not get around this problem by doing a multivariate regression of speed on gas pedal and hill. That's because gas pedal and hill will be perfectly colinear.

This is one of the reasons why you check for multicollinearity [1] when performing multivariate linear regressions; aside from introducing significant instability into the model, if your predictors are correlated, then you're essentially measuring the same thing twice. The stated problem is actually a good example as to why you should avoid having highly correlated predictors in a multivariate model; by blindly pursuing the regression despite the inputs being correlated, we miss out on the fact that there is a relationship present (i.e., the dependent variable (speed) is actually a factor of both of the independent variables (pedal height and hill slope)).

No, you're wrong. It's not with the data. It's with Apple's ability to search. Like I said below, look up "Pier 39 San Francisco". This is a dead simple query, extremely specific, and they point you to a really bad area of SF. This isn't Tom Tom data, it's how Apple resolves this query to something useful.

Search is Google's domain expertise. Apple needs to basically start from scratch and figure out how to create a search engine that will return relevant data based on queries.

It's the same thing with Apple's App store search, it's also terrible. But because we have no choice, we are forced to use it, and hopefully it will improve. But because Google's is so nearly perfect and getting better all the time, why would someone go ahead and use Apple's terrible search engine to help them improve their search?
I wonder how much impact this will have on Embark.
It is incorrect to state that he is only obligated to refund if he DECIDES to cancel the project. By the terms of service, he is obligated to refund if he is either unable or unwilling to provide the rewards. Legally, unwilling loosely corresponds to deciding to cancel the project (or, at least, deciding not provide the rewards), but inability would be judged by looking at capacity, not intent.
How is going from having your app presinstalled on every device and being maintained, for free, by Apple developers to having to write and maintain your own app and put it in the app store a "win"??

There is no win here for Google! Less users (not everyone is going to install it), less data coming in, more money spent, having to hire more dedicated iOS coders inhouse at Google...

People have a weird definition of "win".
Yeah, it had a way to subscribe to a community, and then people would send tracks out to the community. Awesome stuff from people would then just show up in a folder on your computer.

"if you don't know, now you know"

whatever Goldman says, do the opposite.
It's actually much more subtle than "correlation is not causation". More like "goal seeking behavior can remove all correlation from a causal relationship," which is very different since causation normally causes correlation, and normally is you don't see correlation you can be sure that there isn't any causation.
The answer is clearly yes - this largely removes one reason why someone might prefer Android over iOS. Hard to say how big the effect is, though.
What's with the downvotes? The notion of a "greatest year in the history of the world" is silly.
The new google maps on iOS uses vectors

From the blog post: "The app shows more map on screen and turns mobile mapping into one intuitive experience. It’s a sharper looking, vector-based map that loads quickly and provides smooth tilting and rotating of 2D and 3D views. "

I think that it is more valuable to spend one's time focusing on problems and how they can be solved rather than celebrating the fact that things are better than they used to be in many, many ways.

That being said, it is important to periodically remind one's self that things are generally getting better around the world. Failing to keep problems in perspective can not only be discouraging, but can skew your perception of how sever those problems are. Don't let yourself fall for the "Good Old Days" myth.

PyFirebirdSQL 0.7.1 pure Python driver is released with many fixes
That may be your mental model, but what's enforceable is the terms of service, not your mental model.
Well, in this contrived scenario, you can't tell what would happen if the driver _didn't_ push down on the gas pedal while going up the hill. The relationship between the gas pedal and the speed of the car is entirely obscured.

However, in a real world system, the chance that there is zero imbalance is also nearly infinitesimal. You could take the most skilled driver in the world and you would still be able to pull out the relationship between gas pedal and speed out of his driving pattern. Similarly, with the right variables and enough data, you could pull a relationship like the one described here out of economic data.

(As a side note, I think the way in which this article is written is pretty obnoxious. The first 500 words are dedicated to the author congratulating himself for being aware of an idea that he hasn't even explained yet.)
Other issues:

Perhaps unavoidable, but I opened a google document, typed "hello mister how is this working for you" tried to position the cursor before the first 'i' in that line, and the blinking cursor appears over the s. Expanding selection by dragging also isn't clear.

Tried copying the selection using the right-click menu (long-press) but this resets the selection.

Repeated selection.

Tried copying selection via edit menu (not really convenient) and then I get a notification I need to install the web drive app to support cutting and pasting.

Perhaps this can be solved by adding cut/paste to the menu bar. I would not mind having left/right cursor control in that bar too (but I can see how that would interfere with the history function).

Not saying all US traffic circles are like that of course.

"The doom-mongers will tell you that we cannot sustain worldwide economic growth without ruining our environment. But while the rich world’s economies grew by 6 per cent over the last seven years, fossil fuel consumption in those countries fell by 4 per cent. This remarkable (and, again, unreported) achievement has nothing to do with green taxes or wind-farms. It is down to consumer demand for more efficient cars and factories."

Statement is made that it's all because of capitalism - yet no evidence is cited or even presented. The chinese reference is amazing too, because we all know the Chinese government has had nothing to do with the economic boom they have undergone in the past decade.

Let alone how nearly 2 generations have been raised to "reduce, reuse and recycle" through educational programs promoted by Government initiatives.

But no... it's all consumer demand that fixed emissions issues. Simple arguments for simple minds.
"There is not the slightest reason to believe in a coming singularity ... Look at domed cities, jet-pack commuting, underwater cities, mile-high buildings, and nuclear-powered automobiles"

That seems like a pretty terrible analogy. All of those examples are possible today, but their cost doesn't justify their utility, and nobody pursues them. On the other hand, it's fairly easy to think of practical uses for artificial intelligence, and research in this area is actively pursued by researchers around the world.

Like I said, it would take someone incredibly egotistical (apparently such as a Harvard psychology professor) to suggest artificial intelligence isn't possible based on where we are right now, where we were 30 years ago, or where it appears we're headed over the next 30 years. Based on this quote, Pinker's conception of the world doesn't appear to extend beyond the span of his own lifetime.

"The fact that you can visualize a future in your imagination is not evidence that it is likely or even possible."

Nor is the fact that some of his childhood fantasies didn't come to fruition evidence that it's impossible or even unlikely. What's his point? One bad argument doesn't right another.

Yes, obviously. That's only a simplified analogy.

Oh come on. I like to make fun of Apple maps as much as the next guy but the reality is that they aren't that bad. Certainly a few more iterations and constant development effort will iron out any quirks.
Does anyone know of any studies that support the article's statement that Apple, when combining OSX and iOS, has more users than Windows now? If you ignore legacy devices still in use I could possibly, maybe, see that. Although, if you count total devices existing in the market, which the graph seems to ignore, I just can't agree with that notion.

Plus, based on the speed of innovation in this market, making predictions up to four years into the future is highly optimistic on their part.
If he shuts it down, then Google wouldn't have much incentive to make a great maps product on iOS. It would stay stagnant like it was beforehand.

Well I can not surely say what causes each failure (not even the manufacturers know for sure, that is why they make tests continuosly), of course not all the failures are due to phones. But saying that phone interference is not a possible danger to the integrity of the flight is quite bold, as I doubt that you have experienced a failure of that kind as a pilot or as a flight engineer. I also doubt that you know what can be the outcomes of a misguiding indication or or complete fail of a system.
You are surely oversimplifying the matter.
Planes are not data centers, they experience a great deal of vibrations, temperature changes, extreme humidity changes (from very dry to lots of condensation). All the circuits, cables, sensors computers, pipes, pumps, metal sheet, everything inside a plane will behave over time in strange ways that are not fully understood even today. A weakened electronic sys(with already corrupted signals) may not support the kind of troubles that a nominal one could do with ease.

The wall you are talking about is between investment banking (private side) and the rest of the bank (public). The two sides don't see each other on the internal IMs systems, if they try emailing each other, their emails get auto routed to compliance, etc. This ensures that private insider information from M&A advising to the companies doesn't leak and get traded on.

In this case Goldman analysts and traders are both sitting on the public side of the wall. Neither analysts or traders know anything private about the companies that can't be found out or calculated without some sleuthing. Additionally under current regulations in the US, the analysts are required to release their research reports to their clients simultaneously( no client advantaged over another ).

When my father passed away last year, I went through his library of technical books. I recycled 900 pounds of books.

Most people who saw this happening wanted to give the books to the library, to a church, or hold a yard sale. But my mother understood, when I explained that my dad wouldn't really want some unknowing kid to learn something he'd just have to unlearn. Nobody needs to know the ins and outs of Windows 95 application programming.

I really think that donating outdated books to libraries and such is just a way of passing on the guilt of recycling large volumes to the people who work at the library. Be bold, do it yourself.

Edit: Of course, do something meaningful with the current and timeless books. I came home with a copy of K&R's The C Programming Language and a few others, and I left the full set of The Art of Computer Programming in my dad's library. I explained to my mom how that set represented my father's entire library.
So when Apple decides drop Google Maps as their default, they probably thought that it'll bring more value to their iOS platform. But obviously that didn't happen.

Now that Google Maps is back on iOS, I agree that it's a win for Apple as well. But someone please explain it to me how it could have been a win for Apple to drop Google Maps in the first place?
Yeah, if it's a closed system with no people or money added or removed the average would stay the same.
Now there is none. Android has already won, if not by profit margins then by market share for sure. Let alone the fact that (as others pointed out) Google gets your attention and your searches, so they do not care. Google created Android precisely for the reason not to give any vendor (Apple predominantly) power to lock them out of mobile search markets.
Come on you incorrigible pessimists, lighten up. There is obviously some tongue-in-cheek and inaccuracies in the article, but also some profound truth. This is the greatest time in history to be alive as a human and we might as well recognize that.

Exactly. This whole article could have been distilled down to http://en.wikipedia.org/wiki/Multicollinearity (but I still thought it was a good read)
I am. I talked about it on the other, now super long, thread and my reasons boiled down to: I prefer how Apple Maps works and feels, in general for my usage it works fine, it has gotten better over time and if I stop using it it won't get better.

Horses for courses, if Google Maps scratches your cartographic itch then go for it but please don't say things like "shut down the entire Apple Maps division" as some of us are using it very happily and are watchfully waiting for Apple to start pushing their datasets forward.
The problem is that a wrong map is a lot worse than no map.

If you don't have a map, you might ask a local for directions or take a cab if you're in a hurry to get somewhere that you don't know the location for. If your map is wrong, you are more likely to actually end up in the wrong place -- and then become that much more confused and make poor decisions while trying to find your way without it.
Nokia Maps give one the ability to download maps locally to the phone. Do either Google Maps or iOS Maps have that feature?
The farms in the middle of Narita Airport are pretty amazing. One second you're peering out the window of your 747 at a typical airport taxiway scene, then suddenly a farmhouse passes into your field of view for a few seconds apparently just past the tip of the wing.

Yes and no. There is some not-so-pretty trickery involved on both the native side and the JS side. We have an invisible layer on top of the browser on the native side, and call the JS code which generates the appropriate events and scrolls the appropriate elements.

I agree. 'Other' category jumped from 0 to 29% as well. Likely at this point they started considering a wider range of devices or something like that.
Can you elaborate? If you are drawing to the buffers at half the rate (and correspondingly swapping them out at half the rate), how would that not be easier on the graphics processor?
Donate to your local library would be my suggestion.
These layers aren't literal, though. For example, the JS VM can generate native machine code that can run just as fast as the assembly in layer 1. It's literally in the same language. (It won't be as fast always, of course, but in some cases it will.)

Also, there is no reason Lua in JS could not run at similar speed to JS, if the translation from Lua to JS is efficient enough. Whether that is possible depends on how close Lua and JS semantics are. That could also be at least partially achieved by using a Lua VM that has a JIT, and implementing a JIT backend that emits JS. Such an approach could be quite fast.
I think people need to ask their parents, "hey mum, dad, how did you use to find things before smartphones?" and they'll point out things like road signage and maps, and asking people for directions.

We've really only had mobile mapping for about 7-8 years now, it's amazing how quickly people have forgotten how to get places without it.

Its fair to request a refund if you invested through a vehicle with terms that require either fulfillment of the offered reward or a refund.

The terms of service at Kickstarter require a refund if the project creator is unable or unwilling to provide the offered rewards, not only if he didn't really try.

It has to do with tax rebates for more efficient cars, ever increasing EPA fuel efficiency standards, ever increasing EPA factory emissions standards, heavy subsidization of renewable energy not just by the West, but by China, etc.

Especially since Apple are clearly working to improve their own maps. If/when they hit (or near) parity, they'll have the massive advantage of being bundled.

At least before, they were maintaining a long term position as the major maps app. If they lose 90% of these users when in a year or two when Apple improve their maps, it would just have been a wasted opportunity to sell androids, especially the high end ones.
