The issue of crowd sourcing answers to questions is a very interesting one. I've recently been reading research in this area with a colleague, and it is far more involved than the article makes it sound.

If you are interested, one of the first people to work on the problem were Dawid & Skene [0] back in 1979. They were trying to solve the issue of clinicians talking to patients and asking how they are. Each time they asked, the patient may give a slightly different answer. The goal was to estimate the "true" answer from the number of various "noisy" answers (sound familiar after reading the OP?)

The general intuition for most future research into the topic is that if you tend to agree with others more often than not, your score goes up. If your score is higher, your answers are trusted more.

Then there are a whole bunch of interesting additions to this principle, such as factoring in question difficulty [1] (e.g. questions which have the most disagreement can be considered more difficult, and hence you may want to ask more people about these questions to get a clearer picture). It is also helpful to seed certain questions for which the answer is "known" (may or may not be possible, depending on the project). Then you can use the answers to these questions to help score people even more accurately.

An even more interesting approach is to take into account people who answer adversarially, that is, they always answer incorrectly (either due to malicious intent, or they consistently misinterpret the questions in a backward fasion). If you have somebody who answers incorrectly 90% of the time, then they provide almost exactly the same information as someone who answers correctly 90% of the time. All you need to do is flip their vote once you've identified this.

The whole field is very facinating, and there seems to be more and more publications coming out with interesting approaches to the problem.

Correct me if I'm wrong, but I infer that you're using "we made it all up" as a pejorative toward mathematicians. Of course mathematicians invented the terminology, notation, and methodology, but that's not a bad thing. It's a great thing, just like it's great that engineers "make up" bridges, chemists "make up" pharmaceuticals, writers "make up" novels, etc.

Why is that even a question? It should return the correct answer, of course.

Edit: At the very least, that behaviour should be a configurable option for those who desire something other than what most mathematicians accept as being the correct answer.
Cool idea. Has anyone done this before?

Then it's not arbitrary; chosen at random or on a fleeting whim, without reference to a reason or system. It was invented to fill a specific need based on certain limitations.
What exactly do you mean by fundamental truths here?

Mathematics is an internally consistent (for the most part) logical framework that is extremely powerful in expressing our knowledge about the world.

However, that doesn't mean that there is some intrinsic correctness about it or its concepts.
Are PDF warnings relevant anymore? Of late Chromium and Firefox display PDF natively, sandboxed(?).
When talking about whether something like Docker is production-ready, the "at worst" can be a lot worse than that, particularly where security is concerned. Months back they found that Docker's API wasn't sufficiently locked down, for example, and could be accessed by an untrusted process. So they changed that and locked it down.

I don't see anything unreasonable about waiting to use a package until the devs themselves say it's "production ready".
What does that even mean? You can express anything as an "isn't."

This is such a perfect description.

"I'd happily commit each line individually, to ensure that any potential data loss was as limited as possible, of course."

Bah. While where I work has never even flirted with that metric, general agreement in my team was that the first thing to be done in the event that ever changed was write a git filter that committed one character at a time. I suppose you could take it further down to one bit at a time if you really wanted to; once you had the code for one character at a time, one bit at a time would be a trivial extension.

Less humorously, I've been complaining that our email notification system sends out a separate email for each commit in every new git branch... that is, if you are on a branch with 100 commits, and you take a new branch and commit that branch onto the server, our emailer seems to believe you just made 100 commits, and sends 100 emails. Or 1,000, as the case may be. One of these days that thing is going to take out the entire corporate email system.... of course, one never fixes the problem until it reaches that state, so I'm just waiting....
This is disappointing. I have all my backup files on Ubuntu One, and I've purchased extra storage as well.

Between various bugs, shit that just plain doesn't work, cancelled projects and now Ubuntu One, it seems Canonical likes shooting themselves in the foot... Maybe if they had actually marketed Ubuntu One and made it better they could be a Dropbox competitor. Then again, maybe they just don't have the expertise to make half of this shit work.

No wonder SUSE is a billion dollar company, Red Hat a multi-billion dollar company (with over a billion in yearly revenue), and Canonical a trust fund baby...
https://github.com/yaur/SpellUnit Is something I wrote for C#.

It currently only has support for literals passed in to exception constructors (I common pattern in the code base I care about) and strings passed in to attributes that get bubbled up as API documentation. I'm working on more complex stack modeling stuff (using Mono.Cecil if your interested) to find literals passed into an arbitrary named function (e.g. log messages and functions that display in the UI) when I'm not busy with other stuff.

With somewhere between 500K and 1M LOC there is no practical way to spell check everything. There are just to many connection strings, regexs, format strings, etc to spell check every literal. If you add in comments you also need to worry about jargon that won't be in a standard dictionary. That is why I personally picked very narrow checking instead of the broad checking that is trivial available as an FXCOP rule.

This piece is entirely incomplete. It purports to examine the entire ecosystem from the angle of a single company, and writes an article not unlike painting eagles (or vultures as the case may be) as the villain conspiring against the innocent rabbits.

Let's go through this logic again. So a hedge fund comes in, buys a company, levers it up with a partner's money, leaving a pile of toxic debt on their neighbor's lawn.

With you so far.

The company issues more junk bonds in order to pay it's existing creditors, and that gets snapped up by other PE firms / Hedgefunds, who need it in order to fulfill a never-ending quest for returns.

Yup got it.

GC then goes bankrupt and the banks are evil.

Whoa, wait a minute. Where is this whole process did anyone get hurt? The author seems to think Guitar Center, and YOU, the average consumers. But in order to really understand that, let's look back in time.

Guitar center, if were any other company, were started by a few enterprising individuals with a passion for what they do. In turn, they were able to build a great business, and grow it to serve the entire country. After a while, wanting to cash in their success, they sell the company to a buyer, knowing very well what they planned to do with the company. The rest is history.

Not as clear anymore is it? Now lets look at what happens in the future.

GC goes bankrupt. Or it doesn't but becomes irrelevant. The 800-pound gorilla in the space dies, and there's room in the space now for another innovator, a new group of passionate individuals who can now bring their vision to life.

And the cycle starts anew.

This can of course be far from the effective distance, but since the data being communicated is so small it should be possible to keep sending the data until you can acknowledge that it has been received.

If feature status were a Facebook relationship status, many might say "it's complicated." ;-) Most of the time, it's not actually a question of engineering resources. Stay tuned as we update more and more stuff to "In Development".

I'm not sure either, but I want to say that since the sound will be at a given frequency in a given pattern, you could probably pick it out relatively reliably...

Also, unlike fire alarms, I think I'd be less worried about false positives or the thing not working -- it would be an annoyance, not something that could potentially endanger my life.

Really? What aspects of IE 11 are "hostile to the Web"? It looks pretty OK to me.
No one seems to have pointed out yet that code size as a predictor of error rates (and as a measure of complexity) is one of the few findings from software engineering research that has been replicated many times. It's not clear that the studies are very good, but at least they exist. We've discussed this on HN more than once.

I'm longing for the day when people realize how significant this finding potentially is.

NASDAQ made the situation a little more complicated by reporting GOOG as the price of the Class A share (soon to be GOOGL) plus the price of the right to have a Class C share distributed to you. My brokerage linked me to this FAQ: http://nasdaqtrader.com/content/GOOGfaqs.pdf
"Real-time" is a bit of a misnomer as far as databases are concerned, especially if you're talking about a system that defaults to eventual consistency. I think they would have been better off saying "high-availability".
Why link to the PDF? Better to just link to the abstract: http://arxiv.org/abs/math/9205211

Edit: To be clear, this is good practice when linking to arXiv in general. From the abstract, one can easily click through to the PDF; not so the reverse. And the abstract allows one to do things like see different versions of the paper, search for other things by the same authors, etc.
I am 100% sure they can be written in native code but don't have any reference to give you for now.

Great pos! The more I learn about bitcoin, the more I feel like it still has a long way to go. There are a few hurdles that can not be easily solved now: 10min transaction time; deflationary (this pretty much means it would have a hard time to act a real "currency" based on nowadays economic thinking); the resources wasted in mining and the potential consolidation of mining; the programmable aspect is very limited today. What is your take of it?
Gandi does have an office in San Francisco, but our registrar service is accredited and located in France. It is under EU law.

Those who have been following the industry's responses to the massively reprehensible, illegal dragnet surveillance will know better than to take any company at their word as they swear up and down that they care about their users' right to privacy. So I know this will be taken with a grain of salt (hell, I take it with a grain of salt and I work here)...

But as far as I know, and I've asked around, we _actually_ do protect our customers' privacy to the maximum possible legal extent.

The day I find out otherwise is the day I no longer work here.
But it is arbitrary; subject to individual will or judgment without restriction; contingent solely upon one's discretion.
I have a problem with this part of the explanation:

>However, this definition extends quite naturally from the positive integers to the non-negative integers, so that when x is zero, y is repeated zero times, giving y^{0} = 1,
which holds for any y. Hence, when y is zero, we have 0^0 = 1.

When y is zero, don't we have 0^0 = 1 x [y zero times]? Maybe I'm conceptualizing it incorrectly, but I'm envisioning an empty space where y would be, akin to an empty set. 1 times an 'empty set' is _not_ 1, it's one empty set, which rubs me as another way of saying nothing/zero, not 1.

I know my language is imprecise and I'm probably describing empty sets and the definition of zero incorrectly. The point is that the last step of his explanation doesn't sit right with me. Just because Y exists zero times does not mean you can just throw it out of the multiplication.
There seems to be a push to diversify and expand Google's income recently. Google Play Music All Access, Google Helpouts (20% cut), this stock change, Google fiber (while competitively priced, I expect there will be long-term profits), Google Glass, etc.

I have been noticing this and assume it's meant to help them fund their robotic and autonomous car projects. These are likely capital-intensive segments of the company.

First things first: What do you bring to the table, besides having an idea? Inside experience in your target industry? Industry contacts? Venture capital?

If you bring any of the above, it's a non-issue. If your hacker runs off with your idea and tries to compete with you, he/she will go down in flames.

If you don't bring any of the above: Seriously stop and evaluate whether or not your "big idea" is actually worth pursuing in the first place.

Ideas that don't come from years of experiencing an industry's pain points from the inside tend to be very risky propositions. (This includes about 100% of consumer-oriented software businesses.)

In this case, your best bet might be to give up on finding a co-founder, and find a contractor that you just pay up front. People are a lot more willing to sign non-disclosure agreements when you're waving cash under their noses, which in turn resolves your fears of them stealing your idea.
I did not encounter this convention while working on my math degree. I am surprised that none of the characters in the article said "0^0 is nothing, but limits of the form 0^0 can be any nonnegative real number or infinite".
Ah,yes, good suggestion to add to our list on the site. Look for an update soon from our JS engine (Chakra) team's plan.

I don't understand why Google are so bad at advertising and marketing. Probably the only reason Chrome itself took off was that they put a big ad for it on the Google homepage. Maybe they should now switch that ad and advertise something else?
How about "I really enjoyed microcorruption and the crypto challenges, but am mostly working as a mechanical engineer"?
In JavaScript, Math.pow(0, 0) == 1.

In Python and Ruby, 0 asterisk asterisk 0 == 1.

In Windows Calculator, 0 [x^y] 0 == 1.

So I guess the consensus is that you should return 1.
They're not selling any new shares, just splitting existing ones. So I suspect no.
In the short term, I think it will have a hard time gaining use as a currency. A few currency scenarios might pop up, for example countries with unstable government or corrupt governments could see people store $ in BTC instead. However, I do think it could be very valuable as an application. Like if you layered it on top of the existing payment system to provide better security/anti-fraud.
Should You Bootstrap Your Startup Or Raise Capital?
I... okay, but you're not really responding to the intent of the message which was saying that math isn't a bastion of purity and fundamentally and wholly right and perfectly designed.

And if math had been handed down it would all be in an old holy book, which it clearly isn't.
No. This essentially means there will be two classes of Google Stock (A and C) with Class A stock having more voting power than Class C stock from a shareholder prospective.

This dilution of shares essentially gives those with a large share of stock options (like Brin & Page) more power.

Edit: As a user pointed out, Class B should be Class C

Yeah that's true of course and why I assumed they are non-interacting. It's of course a gross simplification of the real theory but it explains quite well why entropy increases in a closed system and as an explanation is not conceptually wrong.
Correct, they (or anyone else) are not making money directly off this. Just like a regular stock split, when there is a 2 for 1 split each share is instantly worth 1/2 and no one is richer.
What Sanddancer said, they are investing in their Tiva (aka Cortex M series) parts and de-emphasizing the OMAP line. (they may have said the OMAP5 is the last of that series) I don't think they felt they were offering a lot of value over the other Cortex A9 vendors.
My Startup made $290,475.48 in 26 month and I'm shutting it down
I started a startup about 26 month ago. At the beginning it looked pretty good. Now it's 4 employee a service industry small business, which makes me very depressed.

I have no motivation more, I think I'm burned out. Not because it's failing, but I really have no interest in this industry. It made about 500k in 2 years and appr. 290k was pure profit. But it's still a boring constant revenue small business which makes me money for living.

As a kid who loves gadgets, coding and computers I'm going to shut it down and start something better that can probably change the world.
