Wasn't the Blub paradox particularly in relation to dynamic languages with advanced metaprogramming capabilities?
I'm not quite clear on this: Is this a theory of how backpropagation might be constructed using known neural mechanisms as building blocks, or is this actual observation of how the brain really trains neurons?
I don't really see how .com or not translates into being genuine or not.

Having been a founder for four years now, I have learned that the word "startup" usually scares potential customers. It is actually a good thing to seem more established than you are. However that doesn't mean you are disingenuous either. It is not black or white. You can look more established: .com domain, decent website, proper terms and privacy policy, no beta or "coming soon" wording on website, etc. However if someone asks directly how established you are, you are truthful.

What the potential customer wants to know is if they can trust you, and you won't be gone tomorrow. Therefore if you are truthful about the company's state, but seem like you are established then more people will look past the word "startup" since it will be obvious to them that you are serious and have some idea what you are doing.

In other words, you dont need to go around yelling at the top of your lungs that X is a startup. That strategy will most likely fail. But you certainly shouldn't deceive people either. There is a line.

Things would probably work themselves out if there weren't so much in the sugar subsidy. If sugary treats and drinks were rare instead of common we probably wouldn't have as much diabetes or overweight people, myself included. I feel this kind of stuff is sadly typical of the world we live in, propaganda at its finest.
"Las Vegas sucks up a lot of water. In 2010, the latest year for which nationally comparable figures have been released by the US Geological Survey, each resident of Clark County, which covers the entire urban area of Las Vegas and its suburbs, used 234 gallons of water every day. In California, the figure was 181 gallons. But in recent years southern Nevada has dramatically cut its water use. Between 2002 and 2014 the region’s consumption of Colorado river water fell by 30%, even as Clark County added half a million residents."

This seems to confuse things, implying that Vegas is becoming more thrifty when measured from 2002 to present but the snapshot from 2010 shows strikingly high utilization. Where did they start, 300 gallons per day per person?
So let me get this right:

We have billions of complex chemical processes involved in all of this, and know things like "absorption rates of medicine, vitamins, and nutrients" are affected by everything from random vitamins to environmental factors to whatever else.

But body mass, that we have down 100% for-sure, and it's just that simple formula, no variables, no possibility for any other affecting factors.
Sure.
Can't a mathematical theory compress, generalize, and map out many relevant empirical facts very well without needing ontological commitments to the generalizations themselves?

The real numbers seem to be a perfect example: if you work in physics at scales where quantization doesn't noticeably apply, the only way to calculate correct predictions is really to use real numbers and continuous (mostly Euclidean) spaces. But that doesn't mean physical objects are ontological shadows of our mathematical abstractions, as Plato's Allegory of the Cave portrayed it. Quite the reverse: when you get down to a sufficiently small, fundamental level, objects, space, and time stop being continuous and correct experimental predictions only come from using discrete formalisms.

You can then proceed to ask, which one is Platonically real, the continuous mathematical spaces or the discrete physical ones? But I think the answer there might be, "Who says anything is Platonically real? The map is not the territory, so shut up and calculate."
GeoIP can be used for good. For example it can be used to set defaults for various forms and choices. Why should you have to scroll past about half the world's countries just to select yours? The most likely airport I want is the closest one. Same for store locators.

Estimating my taxes, shipping charges and delivery date are great too. Even sorting products and choices by what those in my area prefer is great too.

The geoip doesn't need to be street level accurate, but to the nearest ~30 miles can make the online experience much more pleasant and sensible.
At every turn the GEBN scientists seem to acknowledge the role of excessive caloric intake and a sedentary lifestyle, then briefly handwave the former as overhyped - a large excerpt from one of the linked GEBN "Portfolio Items" containing a bald-faced example[0]:

>Most of the focus in the popular media and in the scientific press is that they’re [...]blaming sugary drinks and so on. And there’s really virtually no compelling evidence that that in fact is the cause. [...]

The big problem is we don’t really know the cause other than, well, too many people are eating more calories than they burn on too many days. But maybe the reason they’re eating more calories than they need is because they’re not burning many."

So - he does know the cause. A combination of inactivity and overconsumptiom, both of which are remediated with lifestyle changes that invert their prefixes. Why abandon the latter, simply because each is well reported?

punishment seems to fit the crime in this case. you knew the rules, you swore to follow the rules under oath as a professional duty, and yet you broke the rules. people go to jail for a lot less. for instance not even knowing the rules.
It's like the equivalent of alcohol companies and their "please drink responsibly", except this is "please exercise".
Even in AI, deep learning is not the state of the art in the majority of domains. E.g., in QA Watson is still the best in Jeopardy style general QA. In general game play, statistical methods rule, etc.
I think it's probably just that you have far more relevant experience with reading code. Math is its own language, and math departments only really start teaching how to read and write it in Real Analysis classes. As my math professor stepfather said his advisor once put it, "Everything before that is just to keep the children from running in the halls."
Got at least 3 downvotes without a reply on this post.

Pretty good demonstration that everyone (EVERYONE!) has some religious beliefs they can't stand to have someone call into question, even if they are likely the type who points out when others have the same problem.
Gross. What if I don't want to signal strength? What if I don't want every aspect of my business to be a dick wagging contest?
It can get complicated for sure, but to the best of my knowledge it is an axiom that if you eat less than you burn, you will lose weight. Vitamins and absorption rates have nothing on the laws of thermodynamics.

Now, if your BMR is 2000 and you eat 2100, poor absorption can still cause you to lose weight.

But if your BMR is 2000 and you eat 1000, there is no possible way you can gain weight.

If you know how to gain weight on a calorie deficit, there's a lot of starving people in this world that would love to learn how.

You've inadvertently answered your own question. There are actually several "cross-platform native" toolkit wrappers, but they solve the problem at best poorly, since they all suffer from the same deficiencies:

1. C has an almost non-existent standard library, and C++ has a relatively weak standard library (compare Java or Python). This means that relatively basic concepts like "lists" or "iterators," which end up being common in GUI code, end up needing to be massaged slightly differently for any library that uses them.

2. Invariably, the desire list for GUI libraries starts requiring platform support logic that's very, very different for different platforms. File picker dialog? Now you need to handle filesystems. Printer dialog? Goodbye!

3. Even where features are more or less identical between different platforms, how they work actually tends to differ at a fine-grained level. Change the font, and all of a sudden text flows differently; what may have fit a fixed-size window no longer fits. When you ask for the union of possible features instead of the intersection, you also make sure that the toolkit has to get into very low-level details of this stuff (e.g., double-buffering, damage rectangles, pixel drawing), where these differences are much more noticeable.

4. UI conventions themselves are actually very different across platforms, particularly if you include mobile or tablet form factors in addition to desktops. So a toolkit that wants to be as-native-as-possible would require UI to be designed and specified only at very high levels, to the point where it's not a thin layer around the UI toolkit but rather a component that dictates the design of your application.
Cyclone B is just the english translation for Zyklon B.
Very much a theory, which is inspired by recent successes in training artificial neural networks. It is consistent with our observations so far but certainly not proven by any means.
I have a laptop that has an intel cpu, and a powerful discrete amd gpu. Even though on-die gpus have gotten better, there is still a considerable difference in performance between on-die and dedicated. AMD and NVidia both realize that there is an onboard chip that can do the common stuff, and so they have made the ability to turn the dedicated off when needed.
Sugar would be bad but it's even worse because it's high fructose corn syrup.
Diet soda is not a panacea http://www.npr.org/sections/thesalt/2014/01/17/263141134/die...

"What we've seen from animal data is there is something metabolic that changes when you consume artificial sweeteners," says Bleich. "The brain is tricked into thinking it is less full."

So what's going on? Basically, when we eat sweet-tasting foods, that signals our brains to release hormones to process the sugar. It's part of a mechanism that tells the body how much energy it's just taken in, and when it's had enough.

But in people who are regular drinkers of diet sodas, the theory goes, the body gets confused and no longer releases enough hormones. As a result, researchers suspect, diet drinkers end up eating more — and gaining weight.

Ultimately it might not be any better than drinking normal soda. I'd be pretty terrified of this if I ran a soda company.
Stop the FUD. Not all calories are equal.
I know flippant comments are not encouraged here, but this headline is probably the least surprising thing I learned this week.
It's thermodynamics dude. Your body only gets so much of its mass from the atmosphere with your lungs, the rest of it comes through food. It can't make mass.

Fat tissue is no exception. Your body is only able to make it if you give your body sufficient raw materials to make it.

Similarly, if your body is doing work, it is burning energy. Human bodies are not perpetual motion machines, they exploit energy stored in chemical bonds. You don't get that for free, you get that from the food you eat.

You do not need to fully understand every nook and cranny of a system to examine it from first principles.
"We mutually agreed the position was not a great fit for me."

ie the truth. This happens all the time and anyone who has done any hiring has encountered great employees with this sort of work experience. In fact, most experienced devs have either made the same decision themselves or wished they had.

Leaving a job is not the end of the world for either party, don't over think it.

If it becomes a habit that is when red flags happen.
"nd others perceive it to be harmful due to the artificial sweeteners"

People perceive a lot of things.
The number of peer reviewed studies on this is astonishing, and they have all found the same thing - they aren't harmful in any way we can possibly measure, in any sane amounts.

If you feed rats ridiculous amounts of sweetener, they have issues (it's something like the equivalent of 5 gallons a day of sweetener)

But if you feed rats ridiculous amounts of water, or apples, or anything "more natural", they have the same problem.
Nobody thinks category theory is easy for nonmathematicians, but the point of it is that it provides a common language for talking about common behaviors across many different, seemingly disparate, fields of mathematics, for mathematicians.
I think there are a few more areas that need to be figured out before the "big bang" of quantum, things like HTS for example but it's obvious huge inroads have already been made (ie, http://www.wired.com/2012/02/ibm-quantum-milestone/) but the part that bugs me about this article is the fact that it is a "highly redacted report that won't be available until January" ... who does that help? Would you even want anyone outside the US to know any of this ... if something under those redacted lines is amazing (in the computational sense), I am sure it is in the best interest to hide it for a while.
Alright, this is yet another example of a title change that goes from a good title to a bad title.

If I hadn't have seen the article before the title was changed, I wouldn't have read it. "Utf8rewind changes for 1.2.1" isn't exactly the best title.

Please change it back (to "Utf8rewind 1.2.1 adds 750 new unit tests for its 13 functions"). That title actually indicates what is interesting about the article, and why it was submitted, not just "here's a random changelog for a random version of a random small library that no-one has ever even seen". HN's title policy seems to have become worse and worse over time, and this is a good (bad?) example thereof.
Unfortunately, the well was poisoned from the beginning. Don't forget that this entire CoC fiasco started because someone barged into an open-source project demanding that a major contributor be ostracized because he said something on Twitter she didn't like. Anyone who sees that happen, and then sees that suddenly the same people who were demanding contributors be chucked out over Twitter arguments two weeks ago are now writing codes of conduct that are getting imposed everywhere, is not going to be inclined to read them in good faith.
Completely agreed. I downloaded the article fully expecting an awesome guide to /Risk/ (the game) strategy. But, once I saw that it was a DEFCON talk, I knew better.

OP: might I recommend adding a DEFCON: tag to the beginning of the title?
As a current resident of Las Vegas, it is interesting to see articles like this written. We recycle 94% of the water that makes it to a drain[1]. In addition, recycled water accounts for 40% of our overall water usage[2].

However, I just broke a 3 year lease after 2 years because of both an in ground pool and very green lawn. Both contributing to a $300+/month water bill 5 months a year. The landlord could not get the HOA to approve landscape changes and the pool evaporated a thousand gallons a month. It is great there are laws for new houses, but there is still a challenge to change for homes built 20 years ago. Add in the electric bill for non-stop air conditioning in the summer months ...

No income tax in Nevada only goes so far. It will be interesting to see how much longer we can sustain our growing 2 million person population[3].

Ask HN: Blockchains
More and more noise seems to be appearing about blockchains. I see the small benefit of use in transactions between organisations, but am struggling for the case for private blockchains and some points of cryptocurrency in general. I don’t know if this is the best place to ask, but everything online is full of jargon and is inaccessible to me.

I have a few questions:

- What are the benefits of using a private blockchain (should I be thinking of it as a replacement to a General Ledger?)? Is this just another name for a ledger with auditable history?

- Can a blockchain exist without mining or without a currency/coin? Will all private blockchains need a “coin”? (eg the Goldman Sachs coin or ABC plumbing coin?)

And another couple of broader questions

- What keeps people interested in a blockchain (and currency) once all of the easy mining is done eg, for people joining later?

- I see that transaction costs for bitcoin keep rising, is that related to the size of the blockchain?

- I thought bitcoin was supposed to be decentralised – doesn’t a group of centralised developers have the ability to change everything about the currency?
1. we don't know how the brain does complicated thing X

2. we have discovered a way to program a computer to do complicated thing X

3. maybe the brain works like this too

This is faulty reasoning and I see it again and again. This is not how to proceed according to the scientific method
Sugar specifically though. It is a cause of high calories due to it's effect of creating a high and then a crash making you hungry again. It is also addictive in itself.

WHO recommend getting it below 50g, ideally 25g per day. I looked on the side of some of the staple things I consumed (milk, bread etc.) and it is tough with modern processed foods to get that low.

If everyone followed the WHO recommendation then full sugar coke is out of business!
Sorry, I didn't meant to imply the Z620/820 supports v3. Just pointing out that the performance jump in Sandy Bridge was significant.

v1 and v2 are socket compatible, but v3 is not socket compatible with the earlier versions, but will likely be compatible with v4 (Intel socket changes usually happen only every other generation). I'd suggest going all new with even a low end E5 2620v3 if you can, which you could for everything other than the GPUs for under 1700 (based on a Supermicro workstation build).
"Well said. Advanced math is mostly about working with properties higher up the chain of abstraction, and then seeing what happens when you bring the insights learned up there back down to more concrete examples."

I came here to say the same thing. I went through a lesser known engineering discipline, "Mathematics and Enigneering" [0] and found that the type of thinking one learns doing pure math proofs has served me well in my eventual career in aerospace systems engineering. I find that the thought process in considering a proof as a high level whole/black box or being able to drill down to the finest detail while still keeping the big picture in mind has translated quite well to my day to day traversal up and down the abstraction ladder at work.

Also, it might not be so easy as just scraping the disclosures. I work at a major pharmaceutical company, and my name is on a paper, along with my affiliation. There are also non-pharma scientists on that paper. The paper contains a line stating that those two non-pharma scientists declare no conflict of interest. A scraper might dismiss that as non-industry, but more than half of the authors work in industry.
Unfortunately, in much of tech opposing the "diversity" advocates under your own name is a great way to get fired, or get a Twitter mob after you (which will then get you fired.) A lot of people understandably don't want to risk that.

>It's silly to imagine that Coke is doing something nefarious (like Phillip Morris denying that smoking causes lung cancer, or Exxon Mobil FUD-ing solid climate science) by encouraging people to get more exercise so that they can consume what they want.

It's silly to assume it's OK for Coke to pay scientists to promote any theory or results in scientific journals. Coke can pay scientists to work on their products and labs. Getting from there to paying to influence what goes to the diet/medical journals and the general public is downright fraud.

As for "encouraging people to get more exercise so that they can consume what they want" that's not Coke's business to do.

And it's BS anyway, since the message "diet doesn't matter much" (which is the inverse of what you started your comment with), will also stick to people not able or willing to exercize.
"that if you eat less than you burn,"

Sure, but both the absorption and the burn rates are affected by other factors.

So calculating calories out is not as simple as looking at a nutrition label.

In fact, it's infinitely more complex:
"Instead, the total caloric value is calculated by adding up the calories provided by the energy-containing nutrients: protein, carbohydrate, fat and alcohol. Because carbohydrates contain some fiber that is not digested and utilized by the body, the fiber component is usually subtracted from the total carbohydrate before calculating the calories."

IE note: these are all things that are going to be digested or not digested (and thus, really count or not really count as calories) at different rates in different people.

(Certainly, there is a max value, but this method won't give you that either :P)
In the long term, Las Vegas is in way more trouble than California. California has several sources for its water, and even though those sources are pretty pitiful right now, there are always be the emergency fall-backs of desalination (at great cost) or forcing the farms that use up 85% of its water out of the state (at great cost to the US food supply). Vegas meanwhile gets 90% of its water comes from Lake Mead, and if that dries up, people will simply have to leave the state. If this drought turns out to be an effect of climate change instead of just being a historically bad drought, it's really not going to be long before this is the situation.

I personally think that Vegas will be attracting a whole new set of tourists at the end of this century as the world's largest ghost town.

In 1997, I drove across the Hoover Dam on my way to McCarran Airport and was witness to water splashing over the spillways. It was a rare and unprecedented event in the history of the dam and unique in my lifetime.

The growth in Vegas at the time was mind boggling. New casinos, subdivisions, schools, hospitals, highways, freeways, it was unparalleled and nothing short of remarkable.

Today, that water level is easily 80 ft. below the top of the spillway and Vegas stridently inches its way back to its old dynamism.

Water has ALWAYS been its most important issue. Like every city, it's not perfect, but it's done a damn good job so far.
This is all completely and totally irrelevant.
Read my other reply. Since the digestion/other rates vary from person to person, you can't simply calculate your calories out very easily, and positing this formula as if it is useful or helpful to anyone, is silly.

What is your proposed mechanism for counting calories in and out for a given person (Note: nutrition labels will 100% fail you here, because of how they are calculating)?
