> It's such a simple measure and it seems to be useful for predicting health issues.

It is good for predicting in general populations, but can easily fall apart with individuals. It doesn't take into account what the makeup of your mass is. Muscle is denser than fat, so a muscular man and a fat man of the same height and weight would have the same BMI, but vastly different health profiles.

The margin is larger IMHO. I'm a professional scientist and I have no one remotely resembling an academic in my extended family. Now I'm not a textbook example of success but I've read about many other scientists in similar boats: Feynman and Tesla both come to mind. Feynman had an electronics hobby as a kid. Tesla's father was fairly set against him becoming an engineer.

I know some people with amazing private school education flounder because of it. They saw crazy competition early in life and it seems decided to settle. I had very little competition in my early years. Being the smartest kid in your undergrad makes you feel really good, and motivates you to do better. Where I really needed guidance is going from the sheltered world to reality (early 20s .. when I entered the workforce and subsequently made the decision to get a PhD).

What I want to try to do is teach my kid to have her own hobbies and be generally happy in life.

As far as I'm aware, this hasn't been tested in court. However, given that courts have been pretty silent on the idea of secret laws and compulsory silences, if it did get there, I'd be shocked that courts didn't rule this way.
I'm not sure it's right to conflate arguments about the possibility of new technology having other-than-positive effects with arguments about the moral decay of society.

I'd argue it's plainly obvious that the end results of technological innovation are unpredictable (how many of us here make novel use of tech to earn our livings every day? who conceived of all this when computers were first imagined?) and that it's plainly obvious that some technological innovation has not been to the greater benefit of man (e.g., the industrialization of war and genocide over the last century)--none of that has much to do with children misbehaving or society losing manners.
BMI is a tool for doctors to use, along with clinical judgement. No doctor is going to look at a lean, well muscled individual and tell them they're at risk for heart disease because their BMI is high.

BMI is something that fails in theory and works in practice.

There's something called "remote hands" and the big DC operators like Equnix offer it. I haven't been in a DC in years. Also just because its bare metal doesn't mean you don't need to design for failure just the same as do with AWS.

And those problems don't just disappear by using AWS they just turn into different problems, certainly more opaque, like IP addresses that disappear from underneath you and the noisy neighbor problem.

Its interesting to me that there is now a generation that isn't familiar with hardware. Knowing hardware will never count against you, especially if you want to do consulting or go work for a cloud provider or need to run a hybrid cloud.

It's about context and how it's presented. The fried chicken thing as a sponsored filter would totally just make sense and be silly.
Activated carbon lined with silver works pretty well. PUR sells these. Unfortunately, the power of activated carbon comes from its pourousness. And therefore it will always filter much slower than the faucet gpm due to the resistance which all good filters will provide. You can try compensating by turning the faucet on very high output. Faucet filters will always be quicker than any pitcher filter because of that ability to add additional gpm pressure.

Regarding BMI:

>In fact, for most people BMI correlates quite well with adiposity. In one study researchers compared BMI to a more direct measure of body fat percentage using skin-fold thickness. They found that when subjects met the criterion for obesity based upon BMI, they were truly obese by skin-fold thickness 50-80% of the time (depending on gender and ethnicity). When they were not obese by BMI they were not obese by skin-fold 85-99% of the time. So BMI is a rough but useful estimate, good for large epidemiological studies where more elaborate fat percentage measurements are not practical.”

Can you point us to a good survey on the subject?
The rules in China are evolving all the time but basically to have an app in China, you need to have an entity in China, have user data on a server in China, follow all Chinese laws, etc. So if Snow wants to keep it's Chinese user base, they will need to implement everything that other CN messaging apps have done, including censoring specific keywords, etc.

The advantage and disadvantages:

1. Finer grained control over what happens, i.e. the script only scales the text of comments, not the question's or title's, etc.

2. Automatic execution and implemented at a higher level, i.e. CSS.

3. Only applicable to specified pages.

4. Can be extended to modify additional elements such as line spacing as user Krapp's code shows.

Mainly, I think the advantage is that it frames layout/readability issues as within the user's control by unlocking features of the browser as a tool rather than a passive consumption device.

Makes sense to me.
when you record someone's BMI and it gets thrown in a spreadsheet as patient 123456 has BMI 23.5 the doctor is no longer looking at the patient. perhaps it's good enough, i don't claim to be able to evaluate the methodology of the study (and perhaps using BMI simply results in more skeptical results, by leaving healthy people out of the low risk group, which I'm fine with - not sure this is true though). it really was an incidental note on my part, but i stand by it. i am a little surprised at how much we're talking about it, i guess it is bikeshedding, which is understandable, im not qualified to comment with authority on much of the material myself :)
Because muscle and bone are denser than fat, and exist in higher proportion in fitter people, two people could easily have identical BMIs even though one is a powerlifter with 5% body fat and the other is mostly made of Cheetos.

>It is good for predicting in general populations, but can easily fall apart with individuals.

While it can "easily fall apart with individuals", the difficulty lies in finding an individual to measure that will make BMI fall apart.

And that's because the huge majority of us is of the kind of complexion and body type where BMI works well.

So, sure it can give false positives, but for a quite small fraction -- besides any other rough medical heuristic does the same (e.g. signs of having the flu can also be caused by 200 other reasons).
The situation is better than what it was - https://github.com/christinaa/rpi-open-firmware
I don't think you should claim to be a researcher on the topic if you're not in the academic system and haven't published peer-reviewed quantitative papers.

"Independent researcher" (w/ a link to the bibliographies of yours that I just looked through) might be a better term.

Hey guys,

I've been working on reports for Freshdesk customers. This is my poc, I know it's very ugly, but any feedback is overwhelmingly welcome.

Thanks!
Yes, but powerlifters with 5% body fat are far more rarer than Cheetos-munging fat people.

So the possibility of such false positives is not that high, making still a good heuristic. Not to mention: if one is a thin, mostly-muscle powerlifter type, they already know they are not obese...

Which instance type were you using when you experienced throttling? This is a documented "feature" on a few of the instances. They give you the ability to burst for a certain amount of time but you can't burst forever.
IMO, the author does clarify this sufficiently,

> In other words, this study argued that the more times D.N.A. replicates, the more often something can go wrong. Some took this to mean that cancer is much more because of “bad luck” than because of other factors that people could control.

> Unfortunately, this simple explanation is not really what the study showed. Lung cells, for instance, divide quite rarely, and still account for a significant amount of cancer. Cells in the gastrointestinal tract divide all the time and account for many fewer cancers. Some cancers, like melanoma, were found to be in the group of cancers influenced more by intrinsic factors (or those we can’t control), when we clearly know that extrinsic factors, like sun exposure, are a major cause.

as well, he only opens with that and aims to debunk the bad luck hypothesis by means of the other two studies. which again I personally have no idea about :)
Silly social network becomes popular for silly social reasons.

That's the definition of "fad", after all.
Aristotle's biology and political science were quite empirical, and are the foundations of the more modern versions. His cosmology was off track because he didn't have the instruments, like the telescope, needed to collect the needed data. His physics was sound for the particular phenomena he was trying to explain, as this article explains: http://arxiv.org/pdf/1312.4057v2.pdf
Fair enough. I don't think that takes away from the points that

- They don't do this for economic protectionism (although I know that the Chinese view this as a benefit of the practice).

- and they are unlikely to lift a block on a social network, since social networks and communication channels are what they are primarily afraid of.
I don't see the assumption in my question - I see that many people pose a question as a way of making a statement, but really, I am just curious how they'd operate differently if they weren't holding so strongly to christianity
I don't want to call these usages in any of AAVE, French or Italian (the ones I've seen usage of) double negatives. They're doubly marked, but it's just one negative.
This is nothing compared to the people who die from lack of access to cheap energy, each year, right now.

It's interesting in 30+ years that island's might disappear.

No deep psychology needed.

With hearts, you open up and you see clogged arteries, for example. It doesn't get much simpler than "too much fat is bad for your heart".

With cancer? It could be anything. And there are tons of different types, seemingly hitting all kinds of people, fat smokers and lean non-smoking vegans alike.
But you can tell by the reviewers if they are verified no?

I have a problem with the independent kindle books, I like to support independent publishing but so many of them are unreadable due to poor formatting and spelling errors. I realize these are low margin but its still the Amazon/Kindle brand.
In passing? The article states that some people aren't willing to leave the islands because they feel that God will save them
Not a pun, just what this immediately reminded me of :) I've always found it astonishing that people would live on an island with such a low maximum elevation.
I wonder how much the disadvantage that causes for the Chinese economy, if it got slowed down at all.
For startup phase, its all about speed, I can provision new machines, databases in minutes which have sane defaults and predictable behavior. I do not have to worry about configuration, backups etc. And, its not about difficulty, its about speed, if I have to recruit one less person (which is ungodly difficult tasks), or spend more time on product, I'll go for cloud.

For large companies its again about flexibility, while they can manage/own data center. Core products with predictable load are good for data center. But in SOA or microservices, where a team is responsible end to end for service, cloud is godsend. Getting a new bare metal server is slow and bureaucratic. Boxes are assigned to cost center and getting them moving around is difficult. Getting temporary servers for an experiment is difficult. So the company has to go for internal cloud or external like AWS

Hello HN,

We are working on an open source game[0] which has the main goal of teaching non-technical players concepts about Computer Science, security and encryption. We want them to take a second look at how our privacy is at risk, learn what is VPN, HTTPS, GPG etc. and get them to use these tools in the real world.

We decided to take this goal to the next level by creating the project "Let's Build a Game", which focuses both on technical and non-technical users. We believe that by submitting a small contribution and seeing it get released to a game they love, will bring a unique sense of accomplishment to these contributors. With this practical experience we want to foster Computer Science education among young students.

In other words, we want to create a welcoming open source community for first-time contributors. Open source projects tend to be intimidating even to experienced programmers, and we want to change that.

I know the HN crowd is definitely non non-technical, but you can also be a part of the project. The article shows some examples on how you can contribute. Our stack is very exciting! Backend is mostly Erlang/OTP + Elixir[1], and the UI is in F# + C# with MonoGame for cross-platform support[2].

We are also undergoing a crowdfunding campaign at Indiegogo[3], and the success of Let's Build a Game greatly depends on it.

Happy to hear suggestions and feedback about the project and answer any questions you might have. By the way, we are a startup and are looking for investors, sponsors and partners. Feel free to ask for our business plan. You can drop me a line at renato@hackerexperience.com.

You could pre compile the script with osacompile if you want, but I wouldn't bother.

I think checking the command runtime would be a mistake. If you expect the command to take a long time, and it finished in just a second or two, you probably want to be notified immediately rather than eventually wondering many minutes later why you weren't. And if you expect the command to take only a second or two, you are a lot less likely to be tabbing away, so you won't be notified anyway.

I see how it is a bad measure for some cases, but I don't think that makes it a bad tool. It's like financial advice that says how much someone should save for retirement or spend on rent based on income. Someone with a normal job progression will probably be fine following it, but for doctors who take out huge loans and eventually have a huge increase in income it's not helpful and a more specific plan should be created. For BMI, most people should aim for the middle of the range and if they think there's a reason that they don't fit the scale then a doctor can be consulted.

I read all my fiction digitally, sure, but for technical/reference books, nothing has yet beat the UX of a paper book, and I'm unconvinced that anything in the near term future ever will.

It's a value argument. You've framed it in terms of stability, life expectancy, rule of law; someone else may frame through a different lens (family, leisure, etc.). You can substitute hunter/gatherer for 1960s or 80s political nostalgia and find a similar argument.
What the author is describing is similar to what was going on with the Mt Gox exchange a few years ago.

You have a product that should be fungible trading at two exchanges. In one exchange you have a free market and what should be very close to the true price of the product. In our example this would be most of the bitcoin markets and the Hong Kong stock exchange. In another market for some reason the price has become dislodged from its true price, this is usually due to liquidity issues. In our example this is the Mt Gox exchange and the Shenzhen stock exchange.

Now there is what appears to be an obvious arbitrage opportunity but if you look closer, and you really don't need to do any real in-depth analysis to figure this out, you'll see that the market is acting rationally by pricing in the liquidity issues to the shares on one exchange.

I mean, if the shares don't trade and you aren't sure when the regulators will let them trade you essentially have an illiquid asset that you can only really trade by brokering a trade yourself with a counter party outside of the stock exchange. And if you ever wondered what liquidity was worth, well you're going to find out that liquidity can be very expensive.

It will be interesting to see just how far the Chinese regulators will push this as it could have spill over effects onto the American and European stock markets.

So if you've ever thought about what you actually own if you buy a share of a Chinese company on a US stock market, say Alibaba( BABA US Equity), you aren't actually getting a share in Alibaba in the same way you can buy a share in Microsoft.

You are actually getting something called an ADR. see: http://www.investopedia.com/university/adr/

It's somewhat similar to the brief case full of IOU's that Jim Carey hands over in the movie Dumb and Dumber. Given that you don't own actual shares in the Chinese company but a proxy for them, the Chinese regulators can have a very chilling effect on these shares by shutting down trading of the actual shares in their market as described in the article.

If regulators were to say suspend trading for Alibaba shares in China, its not entirely clear how to go about pricing their respective ADR shares that trade in the US, well at least it isn't to me. Fundamental valuations would still be useful but what discount would you give them, given that the underlying shares are no longer trading on their home exchange, and what exactly would you own in this case?

TL/DR
Or put another way liquidity has value, maybe the HFT value proposition was right after all? :)
Yes they are? Why can't you act on non-numerical criterion? How did you respond to this comment?
I have a bit of a connection with this incident, I grew up in Simi Valley, not far from Los Angeles; it is not an academic subject to me. In short, they built a defective reactor in a warehouse a few miles away from several cities and covered it up when it exploded.

A number of workers and their spouses (known by my parents) died early in their 40s from cancer ostensibly due to contamination. There is a belief in increased birth defects in the area, but I can't find anything to cite right now.

The shame is that we used to be proud of having rocketdyne nearby, testing rocket engines and such, which we could hear from our school yards. Little did we know how reckless they were, and had had a meltdown a few years prior.
