It's just a recommendation to improve the reporting, no general defense of p-values. Pearson does not imply to analyze a causal relationship. I see the point it's not linear (then you would have had a fitted linear reg, I assume) but still can tell you that missing p-values may cause arching eyebrows :)

In small sample sizes, correlation can easily be significant, often at the cost of low confidence. To the opposite, in large sample sizes, the magnitude of the effect may be lower but at higher confidence. In both cases, results have to be interpreted with caution. The recent p-value debate points towards a lot of issues here. For instance, there have been medical studies overestimating correlations in small sample sizes while other authors seemed to underestimate their long-term large-sample results with correlations in the ballpark of 0.15 (p<0.05).

Did your friend's parents tell you outright they were against the building of new housing? From what you've written it seems you've inferred that they are, but their opinion (as you've portrayed it) is as compatible with a pro-growth position as anti-growth.
I'm a little confused on what you're trying to say. If I read your post correctly, you think software bugs fix themselves because computers find them automatically?

Neither is true.
You can get lattice FPGAs for a few dollars each from distributors. Zynq's in volume are reportedly as $15/each. Tools are free.

If cost is the main concern, then how low do you need to go?

Hell, I'm only in my second year of med school in the US, and I wouldn't recommend young people go into this profession.
I guess you probably posted this as some sort of joke, but people seem to be taking you seriously, so I am going to take the bait and respond seriously.

I am really at a loss as to how the current SIMD.js API for shuffles could possibly be fast, or how using vector arguments to specify the permutation would make it slower.

No hardware instruction set has an instruction that takes 10 or 18 separate operands the way the SIMD.js API does. NEON has VTBL and VTBX, SSE2 doesn't have shuffling instructions at all (unless you count the rather pathetic SHUFPD, which packs two double-precision values into its output), and SSSE3 adds PSHUFB. All of them use vector arguments to provide the indices for shuffling.

To compile a SIMD.Int8x16.shuffle call into an efficient PSHUFB, the compiler is going to have to figure out whether the s15:0 arguments are drawn from an existing vector and additionally that they all necessarily index into only one of the vector arguments. VTBL is more powerful, but it still needs the indices to be in a vector. So if the compiler isn't able to figure out that you were extracting the indices from a vector, it has to reconstitute that vector in order to invoke VTBL.
Interesting timing: I just got an e-mail for a (free) app that I purchased in the Amazon app store. Only problem, I have never visited the Amazon app store. The Amazon rep on the live chat explains to me that this is because someone entered their e-mail address incorrectly when making a purchase. How does that make sense? Shouldn't you need to be signed in to your Amazon account (or some other account) to make an app purchase? It actually makes you type in your confirmation e-mail address manually? Can someone with experience in their app store comment? That seems like a brutal design decision...
How does electric current through a (non-super-) conductor convert energy to heat?

You have a coupling to other, non-electron/hole degrees of freedom in the system. The stronger that coupling is, the easier it is to transfer energy between the systems and the worse your conductor tends to be.

Great book. There are a few videos of Johnstone on YouTube, including an interview that I thought was interesting.
Doctors are already paid absurd salaries in the US and the barriers to entry already high. As much as we all hate dealing with insurance companies, when I lost my insurance and had to pay for things out of pocket, the difference between what they charged me and what they would have charged an insurance company was obscene. Insurance companies actually do a pretty good job of reducing the costs of medical care, although some of the same power and information asymmetries still exist (that is, I'm saying that doesn't necessarily make the insurance companies the good guys). But the consumer has no bargaining power on his own and he doesn't know enough to challenge or negotiate. And the entire regulatory structure puts all the power in the hands of the doctor, not the patient. I don't see this as being a good trend for consumers. I find this to be very worrying.

Edit: since this my "absurd salaries" remark seems like it might be the most controversial bit, I was thinking of I was referring more to information like this: http://www.motherjones.com/files/blog_physician_compensation...

That's because it sidesteps many issues like how hard it is to become a doctor by simply comparing the pay of American doctors to the pay of doctors in countries with national healthcare. By "absurd salaries" what I really should have said was that American doctors are paid significantly more than other countries.

Of course everyone, no matter what their job, thinks they work too hard for too little pay.

Please also read accounts of people who wrote about the ordinary people's living and working conditions at the same time, such as George Orwell's Wigam Pier, many essays or Down and out in Paris and London, and you'd be amazed at how far better we live now.

Compared to that time (1920s, 1930s), people today (in the developed world) really DO NOT have to work so hard and the surplus is huge.
The big difference is that the software industry still gets away with the consumer paying for defects. This is where the auto industry was in about 1952.

> If it's frustrating to someone working at that company, why wouldn't they feel frustrated working any other place knowing that those people at their former company are still making relatively more than they should?

Because the frustration came from being treated unfairly by the management, which they've cut ties with. Also, they might earn more at their new jobs now as well.

iOS developer here. Pretty damn sure. All the ways I know of for running code in the background, and I've looked at this quite a bit, require at least one launch for them to be enabled.
So a product website has a one to one relationship with the product.

I'm referring to a website where various companies can ADVERTISE their various products and services in any way they want. Basically just present their ads in a civilized way, instead of shoving them down our throat like it currently happens anytime, anyplace, anyhow.

I suppose this could be an extra feature of a virtual market or just a standalone site or both.. but the ad should be tied with places where people WILLINGLY go to buy things or discover new things to buy.
> Doctors are already paid absurd salaries in the US

To put it in context, when I finish all my training, I will owe over $600,000.

It's not the doctors being "paid absurd salaries" that makes medical care in this country expensive. It's lawyers - malpractice insurance can take upwards of 25+% of your income - and it's insurance companies, who have shareholders they are responsible to, and it's hospital administration, whose positions keep multiplying.
I still absolutely love Tinker Tailor as a book. The characterisation is first rate.

Call for the Dead is a really interesting Novel too - Le Carré's first novel and shows both his evolution as a novelist and the evolution of The Circus and Smiley's colleagues. Mendel gets a bit more of a starring role.

Splits and dividends should be factored into the price. I use the adjusted closing price http://www.investopedia.com/terms/a/adjusted_closing_price.a....

However in this case with Ebay it wasn't a stock split but rather a big chunk of Ebay (Paypal) split off into a separate independent company. I think what happened is when Ebay and Paypal separated Ebay share owners gained the equivalent Paypal shares. So this would throw off the numbers.

Tactical Experts Destroy the NRA's Heroic Gunslinger Fantasy
At the time of the article (1932) many families in London lived in slums, several people in one room, and worked from morning to the evening for really poor wages.

Today, they live in an apartment/house where everyone has a separate space, and work at jobs that compared to the people from 100 years ago would look as high class idling.

So, I'd say that people will always spend huge sums to get the housing and services that are within their reach. They just get better housing for the comparable portion of their earnings.
I remember reading about this in Eckhart Tolle's book. We protect our egos by saying we are better than others in one or another. For example, if I can't out earn my neighbor then I can feel better by being more frugal.
I feel sad that the CV of this obviously talented physicist shows that he has spent the last 8 years working in search engine optimization for e-commerce websites. I wonder if society would not have benefited more if someone without a physics PhD took his job and he took one involving physics.
And yet, when Texas put a cap on medical malpractice awards, the cost of medical care didn't go down at all. Surely you have a good explanation for that and you're not just repeating discredited talking points for personal gain.

What's worse is that this will likely go to a single winner. This should be divided into 10 or more draws to have the chances increased, and the payout distributed to more potential winners.

Yeah, multiple people can choose the same number, but how often does that really happen, especially in PowerBall?
The problem is more of over consumption than over population, but I can see why the two would be confused because their is significant overlap. However I find the "over population" argument a red herring to make wealthy Americans feel better. I can assure you if we cut the population of the planet in half but consumed at US levels, that is unsustainable. Just like if we double the population but consume at India levels we'd be fine.

The amazon music application is also one of the most appalling software too, it is messy, it keeps flashing, there doesn't seem to be any logic in how the screens are organised, it's impossible to know where you are or how to go back to one place. I love amazon, I buy half of my music on amazon music, but downloading the music is an unnecessary painful step.

Also they need to improve the quality of the samples vs itunes. When you buy a rock song, there is usually is only one recording of that song. But if you buy classical music there will be many recordings with very different qualities. With the quality of the samples available now, it's almost impossible to tell if a recoding will be of a good quality or not. Itunes has much better quality.
I would argue the desire is not so much for the stuff itself, but the social status that the buyer hopes the stuff will bring them (i.e. status symbols). Proof: a fake diamond ring will be frowned upon, even though noone but an expert with a magnifying glass can tell the difference.

I think this is the main reason very few want a four hour working day -- it feels like falling behind everybody else.

> Because atomic reference counting has much worse throughput than tracing GC. This has been known for a long time.

I know this to be true for ubiquitously heap allocated systems, but I'm curious if this has been studied extensively for stack+heap reference counted systems, where only a relatively small number of items are heap allocated? Seems like reference counting would gain in this kind of environment, as the stack effectively gives you many of the advantages generational gcs enjoy from their nursery, and you don't have to worry about write boundaries, tracing and the like.
Someone else mentioned TheDeck, but another prominent place where this is the case is Reddit (very on topic, minimal % of content, no tracking, approved, etc.)

Two issues that come up:

- They're still blocked by ad-blockers at the same rate as everything else
Pretty good read.

The amount of interventionism, control and central planning involved in what and where gets spent, how tarrifs, and international agreements work is staggering. And this was of course written before the massive bailouts during the housing crisis.

There is also a need it seems to constantly protect the political and economic ideology. Cannot simply, for example, institute basic income, that's too socialistic sounding, and it would involved a lot of ideological backpedalling. So to keep it masked, have to first create a threat -- "Terrorism / Communism / Drugs / War", which creates an industry, then shuffle money that way. Then few friends on top pocket some of the money and the rest trickles down as "jobs".

> When asked to identify the largest element of the federal budget, less than 1/4 give the correct answer, military spending

Well maybe it was true in early 90s' But today if you include mandatory (entitlems) or just discretionary spending budget in the pie. Mandatory spending is dominated by medical (medicare etc) and social security. So that part doesn't sound right. Anyone know more?

As a post script, another aspect that is interesting I think, I after reading this, depending on which ideology the reader subscribes to, they will come out with different conclusions. If they are more liberal -- they might say, we need to be more direct in helping out industry and have more transparent control of how money, power and policy gets distributed. Maybe have a New Deal type jobs program to repair infrastructure, or institute basic income, instead of these convoluted systems. But the more conservative reader, will probably look at this say, these manipulations are perversions and failures, had they not taken place, we would have had a more dynamic, faster, efficient system.

Stroustrup's C++ book is good - the tour in the early part of the book covers many aspects quickly but the rest of the book is helpful reference for explaining parts that are only briefly touched on in the first bit (or if you don't quite "get it").

Also, the rest of the book is well written and worth reading for completeness, if not rather lengthy.
What do you consider to be ''absurd salaries''? A friend of mine is a hard working (50 hours/week) 35 year old GP in San Francisco and makes about $175k all-in, which is about the same as the average base + cash bonus (excluding options) of all our white collar friends (mostly software developers, but also some in finance and other fields). He left medical school with about $50k in student debt (very low relative to the average) and only started a ''real'' job at 30 (8 years after his peer group, who by then had accumuluated savings of several hundred thousand dollars each).

I also know a neurosurgeon who makes significantly more than this but given the sacrifices required to train into and hold that job, I'm not sure any amount of money would be fair compensation.

Medicine is unique in that you have to pay providers higher salaries to work in more remote, less desirable locations, which is the opposite of how most professions are structured. But without this, rural populations would have almost no access to specialist care.
Enterprise applications moved to Java on purpose to lose the issues that memory management causes.
