Your sentence describes what the Fourier transform is, whereas the sentence in the article tries to describe how the Fourier transform does it.

What the article does is translate the mathematical notation to a sentence in English, attempting to retain all the information in the mathematical notation. It can be helpful if you are trying to visualize what each component of the mathematical notation is doing, but if you separate the sentence from the equation, it is not very helpful. For example, how would you interpret "spin your signal around a circle"?
Hydrogen is much less expensive than helium, gives slightly better lifting performance, and is not a scarce resource. Why don't more HAB projects use hydrogen?

The only good reason I can think of, discounting the fire hazard, is the poor reputation of high pressure hydrogen tanks for the reverse Joule-Thomson effect (i.e., unlike most gasses, hydrogen heats up when expanded out of a nozzle), but according to [1] it is not enough to cause ignition.

It's an acqui-hire; they want to build the most talented team so that they can develop the best smart-home devices. They're going head-to-head against Apple, but with a very different strategy. Apple is trying to build the best mobile devices and the best SDK to create a huge market and a great dev environment for developers to build devices for HomeKit. Google's strategy seems to be to build their own great smart home devices.

This article is PR at its most effective. An established founder snaps up a fancy domain name and his PR team convinces a reporter that Quora has somehow failed. I've found no such consensus of Quora having failed as a business (http://www.quora.com/Has-Quora-as-a-business-failed), nor as an expert question and answer site.

Anyway, the problem with Fountain is you still have to ask a question. And if you can formulate a good question to begin with, Google (which is fast and free) might very well provide a better answer than some random domain expert willing to answer random questions for small amounts of money.
DOE Report: HPC Open Source Disproportionate Advantaging to the Chinese
"There has been very little open source that has made its way into broad use within the HPC commercial community where great emphasis is placed on serviceability and security. There is a better track record in data analytics recently with map/reduce as a notable example.
...
It should be noted that the most significant consumption of open source software is China and it is also the case that the Chinese are rare contributors to open source as well. Investments in open source or other policy actions to stimulate creation are likely to produce a disproportionate benefit accruing to the Chinese."
I would say smalltalk has little to do with LEARNING objective-c. The gist is:

Where can I read about the actual strategies used? Perhaps some that aren't used any more. I've read an absolute ton about how to set up a trading system with hadoop and cassandra and blah blah but that's all pretty trivial.

It's gotten to the point that if I'm looking for something on google and have to choose between a Quora link and any other website, I'm going to pick the other website first.
Well, the idea of zones is that the second zone depends on the first zone, the third depends on the second, and so on. It is meant to allow definition and use of a language within the same file, so there is little point in having a different dependency structure, I think.
Neat idea but this is a discrete Fourier transform (the original is continuous, with an integral), and it's only "explained" in the context of signal processing. And even then, the explanation is imperative.

I agree with another commenter that the more useful explanation is in terms of a change of basis.

No, but did it also use java translation? That would involve writing wrappers for many of the native libraries. They would also have to do View/Controllers in objective-c (or some equivalent translator). And finally, they would have to special-case operating systems everywhere. This framework would not at all suffice to do multi-platform development; xamarin, robovm, cordova, and titanium all get much closer to this goal.
There's nothing wrong with a person from country X saying he expects better behavior from fellow people coming from country X. That's all that happened here. There's no reason at all for people to get so touchy about it.
Munger and Buffet both have a remarkable set of experiences. My understanding of reading about both of them (and the book) is that they have a deep understanding of human nature, which is really remarkable. If you read stuff from them through their share holder letters and such, you'll find that they've been saying the same things for literally decades. Which means that they've figured out the core of human nature, figured out how to keep themselves sane and figured out how to lead a good life relatively early on. Besides Munger is very witty, and you crack up quite a bit reading the book.
Interesting! I'm teaching journalism students how to build mobile apps on iOS with Objective-C at UT-Austin. For most of them, this is their first experience programming.
This idea is not new. There have been plenty of QA sites that implement NLP, or have a series of pre-screened "Experts" who claim to answer all your question.

Problem is, it will be difficult to get a user to pay for something when the majority of internet users believe (rightly or not)that there are 1000s of Q&A sites like Quora, StackExchange's family of site covering everything from coding to cooking to physics and science, that are FREE and that do have Quality answers in many instances that are also community curated and rated.

So why would any user pay?
The trick is to learn some things that don't require a lot of company support. "Gold standard" skills, if you like. I sell books and classes, for instance.

Those still get harder in a downturn, but you need less company agreement that your skills are good. Instead, sell directly to people who mostly don't care about your formal credentials.

It's not perfect. But even a little goes a long way.

People join YC to get the contacts and credibility to implement this strategy. But suggesting that they have the ability to implement such a strategy before having such credibility is flawed. The conditions precedent for it to be a viable ptactical are not in place. That's all I am saying.

Chelsea Clinton or Ronan Farrow doesn't need to do Y combinator if they want to launch a startup, they have their parent's rolodexes as assets on their balance sheets. But most people are looking to "raise social capital" along with raising financial capital. And to do this, other considerations come into play.

Of course, one can always use a calculated social transgression as a form of breaking into the establishment. That's also a proven stragegy, but its not without its own risks and is really beyond the scope of what started this comment thread. But it does need to acknowledged, so that's fair.
And it also relies on the rather fuzzily defined concept of "a bunch of points." Which bunch? Some particular bunch, or will any old bunch do?
It's entirely possible to overfit with enormous amounts of data. As people are now creating models with enormous numbers of parameters.
Agreed. I had been impressed with Amazon's initial tries with the hardware space with kindle which really solved a customer need in an innovative way. In contrast the fire line of phones and tv seems to have really taken their eye off the ball. Customers don't want to pay a premium to buy another portal into purchasing things from Amazon.

The idea would be to bulldoze them and then just sit on the land until you need it for some reason. Carrying costs are obviously much lower that way you can't vandalize a lot (although you can dump on it of course..)
I can't fathom why Amazon could not find the expertise to see this one coming.

I mean, let's be real here, it's an extremely restricted platform that cuts you off from tons and I mean tons of great content on app stores we already have, content we're already familiar with.

And then it provides you with sub-par hardware at that price level and nothing more than gimmicks.

And one of the big reasons for all of this? To push a feature allowing people to point their phone at something and buy it on Amazon. Surprise, that's a software-based feature you could build for just about any phone.
The scenario you present is a little "doomsday". You'd have to replace all of your deployed product's chips with cheap counterfeit ones for this to happen -- and you say you have complete confidence in your supply chain.

My warehouse has a couple Sharp Max baggers w/ counter and sorter, which are just as expensive as your medical instruments. The electronics check to ensure you are using only the Sharp brand parts, otherwise the machine refuses to work.

Most printer cartridges won't work in printers unless they are the name-brand cartridge (printers read the chip on the cartridge).

Neither permanently damage the counterfeit parts, but it doesn't matter much if you can't use the counterfeit part you just bought (thinking you were going to save a buck or two).

Frankly, I don't buy the argument that a lot of users didn't know they had bought counterfeit. For a device that retails for $15 and you got it new for $1.50, well, something is up.

Perhaps a better way for FTI to go would be to detect the counterfeit when it's plugged in, then just refuse to do anything with it. (although this would allow someone to get a non-FTI driver to work)

Nest Acquires Revolv
Take my, and everyone's advice, with a grain of salt. Few people have experienced enough launches to offer a very objective view of the patterns, so you're going to have to make the decision for yourself.

As a rule of thumb, from the launches I've seen and been close to, they are not make-or-break for a company/product. You might get a bit of buzz, you might have a TC or RWW article about you, but as I think of successful startups that I didn't personally know, I can remember only a few launch days.

The important factor is in one of two categories:

1) consumer app: the app produces a TON of value, and everyone tells the people they know (viral growth)

2) business app: viral growth is a factor, but there's probably going to be a lot of sales-y activity required.

Neither of these categories are largely dependent on a launch. A launch is more important when you've already got a ton of eyeballs.

Again, this is a rule of thumb, and I'm not aware of a single person who I would say is a true expert around launches.

What do you think?
Yup, least surprising failure of a big-co hardware product launch in quite some time.

https://news.ycombinator.com/item?id=7912878

FTA: "When it launched a few months ago, it was $199"

$199 with the essentially non-optional AT&T plan. $649 regular price, which they would let you buy it at even though the phone was locked to AT&T no matter how you bought it. Into a market where the Nexus 5 already existed at $350 (fully unlocked) and Motorola had even cheaper options for very functional full-Android phones.

Months later and I'm still kind of bemusedly surprised the Fire Phone launched at the price that it did because prior to launch I was nearly certain that a surprisingly low price relative to the hardware would be the killer feature, given Amazon's history and the fact that the phone was designed from the ground up to herd you into Amazon's content ecosystem (and I say that as a happy and high volume customer of Amazon Prime/Instant/Kindle).
> Their own software, I don't know,

I've ranted about this more than enough on HN, so I'll summarize: Samsung's software is consistently complete shit. I would be truly surprised if during a security audit Knox turned out to be secure using even the most liberal definition of "secure".
Agreed. According to the paper: They trained the data, once, with 3-4 months of data from Feb to May. Then they tested the data, once, with ~6 weeks of data from May 6 - June 24.

There was no cross validation involved in assessing the performance of this model. Using one subset for training, and one subset for testing and calling that conclusive is naive.

No interesting conclusions can be taken away from this paper due to flawed methodology and failure to take into account real world variables like bid-ask spread, commissions, how quickly trades can be executed, whether orders will even be filled, etc.
The fire phone (and other failed experiments like the Kin or the various Facebook phones) all seem like they're identifying "locking the buyer into a single corporate ecosystem" as a feature, but consumers are treating it as a bug.
Steep discounts for volume are the norm. Its arguable that the consumer doesn't know nor care why the discount; as long as the vendor/product passes a qualification test.
Question: Why are they able to? Is the ability to lock some FCC regulation, or did Apple leave this ability in because AT&T demanded it?
This iteration is a failure, at least. It remains to be seen if the overall idea of an Amazon phone is dead or not.

I personally wouldn't ever buy one, much like I'd never get a Facebook phone, but it could be that there's people out there who might.
that's great to hear :) let me know what you think about it!

Berkshire-Hathaway was a textile company (and then an insurance company) before it became an investment company.

http://en.wikipedia.org/wiki/Berkshire_Hathaway

"In 1962, Warren Buffett began buying stock in Berkshire Hathaway after noticing a pattern in the price direction of its stock whenever the company closed a mill. Eventually, Buffett acknowledged that the textile business was waning and the company's financial situation was not going to improve. In 1964, Stanton made an oral tender offer of $11-1⁄2 per share for the company to buy back Buffett's shares. Buffett agreed to the deal. A few weeks later, Warren Buffett received the tender offer in writing, but the tender offer was for only $11-3⁄8. Buffett later admitted that this lower, undercutting offer made him angry.[7] Instead of selling at the slightly lower price, Buffett decided to buy more of the stock to take control of the company and fire Stanton (which he did). However, this put Buffett in a situation where he was now majority owner of a textile business that was failing."

As it happens, the thousand-year stalemate was the cause of the original player simply being bad at civ. He kept building tanks and trying to perform land invasions of his enemies, rather than crossing the oceans and attacking amphibiously.

By using a landing force comprised primarily of Howitzers, and landing in a well-developed area, a new player was able to prevent the Vikings from obliterating his army with nuclear weapons due to his presence deep inside their homeland. By constantly reinforcing the army across the ocean, you can defeat the Vikings and move on the the Americans, which have a strong air force but a weak ground military. Ground forces can eliminate American bases and cripple their air force.

You don't want an e-book of this. Buy the physical copy and a highlighter. It's a bible for intelligent thought.
I'm going to have to reread this to really understand it, but it prompted me to imagine the possibility of a simpler antidote to parentheses than described here. If the tokenizer generated INDENT and DEDENT tokens as in python, then the combination of those tokens and the spaces and parens that lisp already has could be translated to other paren patterns and then interpreted as in normal lisp. (Of course strictly speaking even parens are already translated into hierarchical cons-pairs, but that just proves that this sort of translation is not foreign to lisp.) Hmmm, something to think about.
Maybe not a feature, but a selling point for sure, and I couldn't agree more. That said, they don't really advertise the "locked in" part, but it's unlikely that it takes long for the average user to figure it out.

The question "what does this phone do that others cannot" really was never answered with the Fire. (Other than that gimmicky perspective view thing)
ehhh... I want to believe?
Anyone remember reading something very similar to this about a year ago? It might have been the same situation but I distinctly remember an article about crowdsourcing failing due to an attack.
Regardless of whether you agree or not, it's very interesting in that it's challenging the merits of things we take for granted as being "good".

yeah, I don't like the idea of 'spin your signal around a circle', and prefer 'compare your signal to a perfect wave' (multiplication).
Which might still be worthwhile, or at least worth considering if things are truly as far gone as they appear from those blight maps. If the city is having to maintain water, power, sewer, etc. to an entire neighborhood for a couple of homes, having those people move to a different city and shutting the entire neighborhood down would probably save a bunch of money.
