I don't think the article is accurate - usually airplane seats are purchased by the airline (from another company) and not by the manufacturer - and in this size of planes, the TV is usually in the seats.
This is the core problem with outsourcing that we will also face in the software industry - when groups work isolated from one another - the things they produce get difficult to integrate and arrive with very different quality.

Outsourcing is really not going to take over manufacturing. It will have its place, but it has to be carefully controlled and selected - not everything can be outsourced.
Garden of Cosmic Speculation
I would assume it meant per passenger. There's also the savings by having fewer empty seats, a slightly smaller plane gives the airline more flexibility in scheduling.
The interesting part about having spent years in Africa, Europe, Asia and America is that even when I learn something like this, it is mildly interesting, but does not seem to have any effect on me.

I feel like I am jaded - too used to being confronted by the new.

It's almost like travelling too much has taken away the suprise of travel for me.

"So compared to the 777, the 787 is claimed to reduce fuel consumption by 20 percent…"

It was perhaps worded poorly but that's not what the article said: "Dreamliner will use 20 percent less fuel than jets of similar size…" I would wager a lot that if a 777 was redesigned with composites it would likely have similar fuel savings (~20%) over an aluminum 777.

If you take a look at the table in the link at the bottom you will see the 777 is primarily for long-range, high-capacity flights. The 787 was originally intended as a replacement for the 767 and as a competitor to the A330-200. The majority of flights are shorter and carry fewer passengers than the target of the 777. So fuel efficiency is just fuel efficiency and fewer passengers is just a different market segment. The 787 is simply aimed at a different and higher volume market than the 777.

Flipping through it the book seems a bit lacking in substance? It is more like a picture book or encyclopedia, like "look, there all sorts of strange phenomena in physics", without being very helpful for understanding. For example, the chapter "classical mechanics" is a mere 16 pages, and contains sections like "free will".

If I find the time to read 1600 pages of a physics book, I think I'll rather approach the Feynman Lectures again. On the other hand, they also seem quite verbose at times - maybe some better physics book can be suggested?

Edit: the Feynman lectures are great, of course, a great joy to read. But they are a lot of text, too.

In India there's no rhyme or reason for home numbers. They are just the number available when you register your home.

I have a hard time writing the address on fedex mail slips, to mail something to my family.
The address reads something like:

Its no small wonder how it even makes it there.
This isn't a very well informed article. Let me give you some background real quick. I spent my elementary school years in Vegas. I've lived in Southern California for 14 years now and Vegas is still more home to me than here. I love that town.

But anyone who says the business model is perfect hasn't done their homework. Vegas has struggled against irrelevancy several times in the last decade or two. The move towards "familly friendly entertainment" in the 90s is just one example. Another is...well..now.

Vegas is hurting right now because their business is not only tied to the economy but tied to the economy doing well. Most business models do fine in a moderate economy but Vegas requires people feel good about the future which means recovery has to reach a higher level for their business to kick in.

Also the author says "Vegas makes people happy with becoming poorer" but that's not the case. The lure of Vegas is getting rich quick. There's a saying in Vegas that they "Sell you a dream (being rich) and for a brief time let you live it (by waiting on you in the Hotel). But it's all about the dream, not the loss.

Finally the author claims Vegas is full even in the current economy. That's simply not true. A look at the annoyingly pervasive Excalibur ads as of late are enough to prove that. But if you still doubt I suggest you go to the reservation site of any vegas casino and try to find a room. You'll have no trouble..

As for new construction of hotels and luxury condos do a search for Echelon Place (Wikipedia Entry here: http://en.wikipedia.org/wiki/Echelon_Place) or CityCenter (http://en.wikipedia.org/wiki/CityCenter). Both were scheduled to be built by now and both are on indefinite hold because of the economy (among other things).

Vegas is an amazing place but it's successful because it constantly reinvents itself. That's not easy and anyone who claims it is doesn't know what they're talking about.

Is there any theory on analyzing sorting real world objects? Like playing cards.

In a computer, picking the n'th item in an array is O(1), in the physical world it's O(n). In a computer inserting an item is O(n), but in the physical world it's O(1).

Are there any good algorithms for sorting playing cards?

i've looked at it, and i'm not convinced that it does a good job explaining the math the reader doesn't a priori know.

Its one thing to go from mathematical physics to theoretical physics, its another thing to go from pure math with a theoretical computer science bent to mathematical physics and theoretical physics. Does this difference make sense, or am I missing some observation? (i don't know enough to know which is more likely)

I believe the biggest difference is it can fly further than any other passenger jet. A london-Sydney could be done in a single hop rather than having to stop and refuel in Bangkok or Hong Kong.

The difference between the 380 and 787 were the markets that were trying to buy them. The 380 made good sense for UAE carriers because Dubai is trying to be a hub between the east and west. The airlines in the west and east don't want their roles to be diminished so they see the 787 as a point to point airplane. No hub or refueling stops necessary.

After having to deal with Atlanta, Chicago, Charlotte, and Heathrow I'd much rather get to my destination than have to deal with another hub.

Taking the easy way out and appearing smarter for it
rant people don't only know what a browser is, they also don't know what a "Word" or a "Microsoft" or an "Operating Sytem" is. This seems to apply even to many readers of Hacker News, considering the recent "Firefox memory usage" complaints. Firefox is an operating system and I suspect a lot of the time it is actually some plugin or other that is causing the pain, rather than Firefox itself.

So by not allowing plugins, a competing browser can appear to be better. It is the easy way out, yet you can get to look like the better engineer.

The same thing happens with Apple vs Microsoft: Apple has taken the easy way out. They don't support all sorts of hardware configurations. And applications that crash the iPhone can simply be removed from the App store. If a phone with windows mobile crashes, who are you going to hate? Microsoft! Not the vendor who created the faulty software running on top of Windows.

Apple simply throws bodies at the problem - reviewers for the app store, who presumably only have to know slightly more than an average consumer. Microsoft throws brains at it - but the problem is probably next to unsolvable. Another easy way out Apple took was with not allowing Apps to be multitasking. Hence no pesky background tasks slowing down the phone and making the OS appear slow.

Wouldn't it be ironic if in the end the thing that would kill Microsoft would be that their engineers are too good?
What really surprises me in XML Schema is not so much all the half baked stuff they put in and not even the crazy nesting of complex types for instance. What surprises me is what XML Schema cannot do.

One thing it cannot do is probably the most frequently used structure in all structured documents I have seen. It is to specify that a particular set of quantified elements can occur in any order.

The reason they gave for not supporting this is that validators would have to be more than contextless state machines. That's insane. They have created a schema language that doesn't support the most important schema constraint of them all for performance reasons.

Sorry, but the more I read that link the more skeptical I become of its contents. Children do not commit suicide because they've been coddled and suddenly are scolded by a teacher. They commit suicide because they are fearful of the consequences and are pressured to reach perfection. Being spoiled creates children who would rather blame others than themselves. Suicide just doesn't seem like a likely course of action for them.

What I find particularly disgusting about the situation is that an apparent superintendent of a mental hospital is blaming television because, get this, "On the small-screen, the protagonists commit suicide at the drop of a hat." Right, always easier to blame the media than deeper social problems that go beyond recent trends.

Another thing that seems questionable is that all these children come in with apparent self-inflicted wounds. Since when do spoiled brats hurt themselves? From what I know, self-injury is a silent way of getting attention, something that spoiled kids shouldn't have a problem with.

In Holden's mind, yes. I'll assume you've read the book - if not, it really is a fun one to read, not stuffy in the least. But Holden is really nervous of women and of sex. There's the famous (in my mind) scene with the hooker, where he chickens out of having sex with her, because he reasons, perhaps rightly so, that sex with a hooker is unclean. But that's the attitude he has towards sex in general, not just towards hookers. (You could call it ironic that Holden's right in his particular case, but I haven't read the book in years so I couldn't make a strong argument for that.)

To Holden, being this pure, innocent child figure is the ultimate manner of living, and that's why he loves Phoebe so much - he sees her as this embodiment of what he wishes he was. The irony there is that Phoebe is the girl who reveals to Holden that he's got this whole catcher in the rye thing wrong, and that while he's trying to stop from growing up, this poem that resonates so much with him is about growing up. It just happens to use sex as its metaphor for growing old, which is a metaphor Catcher borrows for its plot.

The article makes a case for "the failure of the U.S. education system to prepare the country's next-generation tech workforce":

Many American grads looking to enter the tech field are preoccupied with getting rich, Vineet said. They're far less inclined than students from developing countries ... to spend their time learning the "boring" details of tech process, methodology, and tools--ITIL, Six Sigma, and the like.
There's some redundancy in the mapping of codons to amino acids. Some of the most common point mutations will cause a codon to map to the same amino acid, or a functionally similar one. That's some information that would be lost if you represented DNA as an amino acid sequence.
I've always suspected this stuff is just a mathematician's variant of postmodernism, but felt shallow for thinking that way. If there really is an accessible explanation of what motivated it, I'm looking forward to seeing it.
I honestly have no idea how complicated building a plane can be. What I designed required zero plane building knowledge. But given how long it takes and expensive it is, I think it is more difficult than it looks. There are technical difficulties, and then there are difficulties in dealing with massive, distributed teams. The second one increased problems managing the first, which is why we read that article today.

Two of the main design constraints for planes are weight, and its close close relative, fuel efficiency. Consider those as important as actually being able to fly.

The whole reason my project existed was to reduce weight and increase fuel efficiency. What made the critical component I talked about difficult to make was that it needed to be much more efficient than any of its type ever made before. Its efficiency would allow for less operating current, which would reduce the wire gauge needed throughout the plane, reduce weight by 1000s of pounds, and therefore save many gallons of fuel.

It also allowed for another fuel efficiency gain; It reduced the number of systems operating via air or hydraulics. The air comes from the engine after the compressor stage but before fuel is added. These systems are inefficient because the air from the compressors is very hot and it must be cooled before use. That cooling operation takes electricity, and therefore wastes energy when compared to a system that just used electricity from the start.

I should add that the critical component is not a discrete one like a transistor or resistor. Rather it is a system of its own, like a power supply is a system of its own, but we can buy one and as an engineer consider it a single component.

I don't know Boeing's rationale for TV commercials either. It could be anything from putting the Boeing name in front of Americans for American pride when competing against European Airbus. Or maybe they know that the decision maker at a key potential customer loves NFL football, and Boeing blanketed his hometown team with ads during the games. Maybe the marketing department wanted to use up their yearly budget.

Whatever the reason is, when hundreds of billions of dollars in orders are at stake like this, the ads aren't directed at people who purchase plane tickets. I am guessing the ads are out there to make sure that every plane purchasing decision maker absolutely knows that the 787 exists and that they should buy it, and making sure that every member of Congress (and their constituents) absolutely knows that the 787 exists and Americans should support it, as opposed to Airbus.

Whoever downvoted this, would you please care to explain why? You don't like NP? If so, why? Or don't you like the fact that there are high-caliber people in other forums because that makes you feel small? AFAIK, there is one Fields medallist and two Nobel laureates at NP. Plus a bunch of pure math PhD's and former theoretical physicists. Isn't that high-caliber enough for you??
You need this: http://mitpress.mit.edu/SICM augmented by e.g. Lanczos Variational Principle (the closest to a platonic ideal of exposition for this didactically elusive topic) and various lecture notes for classical mechanics courses http://www.damtp.cam.ac.uk/user/tong/teaching.html. From there move to Byron & Fuller Mathematical Physics and only then you may question where to next, that's the bare minimum of theory in physics. Baez & Muniain "Gauge Fields & bla bla" has very good narrative on one offer what to do after, Sethna Statistical Mechanics on another. Speaking of bare minimums there's a youtube lecture series by Susskind "Theoretical Minimum of Physics" or sth.
I've noticed three distinct stages in the reader's response to the character's response to Holden, generally related to the age of the reader:

1) "Holden's so cool-- I'm just like him"
2) "Holden's a loser-- I'm nothing like him"
3) "Holden's a loser-- I was just like him"

From the article, it appears that the teenagers reading the book these days are jumping straight to the second stage. I hope they re-read it when they are a decade or two older.

Your opinion has to be one of the most unconversant comments I have read on HN in a while. Please stop - Thanks. http://ycombinator.com/newsguidelines.html
I have experienced health care in the US and now Sweden. I can say whole heartedly that I prefer the Swedish system. Perhaps that's cause I have a chronic condition that is costly. I could never get insurance on my own in the US, at any price. I pay more in taxes in line with what my perfectly healthy friends in the US have paid to get comparable insurance (of course if they use it for much they risk rescission and will have to fight the insurance company to pay the bills they should).

In Sweden they worked quickly to put me on a safer and cheaper drug, one that most of the US is dragging its heels to get into place, why cause it costs less than half to treat a patient this way. Office visits go down because it is entirely self-administrable, instead of an IV that has to be done in a clinic.

No matter what medical system you choose there are going to be mistakes and deaths, I just prefer the Swedish system that seems to triage and try and use resources wisely.

I've had things in the US turn into unnecessary tests and hospital stays, in Sweden they recognize this and treat me appropriately. Of course I can't blame doctors in the US, they have the fear of a big malpractice suit if anything unordinary were to happen.
I agree it isn't wrong to expect a good salary and make a good living for yourself and your family.

However, the article is about how American tech graduates are either uninterested or under-trained for work in the industry.

Your comment is mostly reiterating stereotypes of Indian students which is not a meaningful addition to the discussion.
This is classy. A very very useful link on Game theory.
It is nice to be able to pop out of a subway station in Tokyo and know where you are and where you're going after a quick look at the map near the exit. That seems a bit easier under this system, and rail is quite widely used in Tokyo (nearly 4 million each day through Shinjuku station alone).

But that's not why it's done like this of course. They've been doing this for 150 years and similar to this for much longer than that, and they're not likely to change any time soon. Major roads, and some not-so-major roads, are given names by the way.

There are no major advantages. But once you get used to it (and esp. with the advent of GPS), there are no major disadvantages either.
