I enjoyed this article, but the dispute feels a bit contrived. It seems obvious that:

1. Language shapes perception.

2. Biology shapes perception.

3. External reality shapes language.

4. External reality shapes perception.

I'm sure the precise form and extent of each of those "shapes" varies, and I can see why there might be a lot of dispute about those details. But while I can imagine some people wanting to strengthen some of those "shapes" to "determines", I don't see how anyone can reasonably deny any of those statements. (Yes, I think positions like "There is no, objective, external reality" are unreasonable.)

And so yeah, I learned a good bit from this article. And empirical study of words for colours is fascinating and should definitely be pursued. And I wouldn't have guessed that the range of basic colours is so wide. But I found precisely none of the results reported in that article surprising or worldview-shaking.
Why did you deem it necessary to even mention that?

I’m quite certain that people with sleep apnoea for whom weight is a relevant component are quite aware of that. Yours is just a pointless diversion in this context – because what exactly is the your angle here?

Should it be hard for people with sleep apnoea to get treatment? I mean, what are you arguing here for exactly?
Not only the bugs you care about, also the bugs that you actually found so regression won't occur. Regression is a very common cause of production failures and testing is a very efficient guard against that particular class of bugs.

And that's exactly how you should look at this whole spectrum of issues: bugs come in classes and for every class of bug there are detection and mitigation strategies. Testing does not work as a detection strategy for all classes of bugs but it is extremely effective against some classes of bugs.

A complete strategy would involve much more than just testing.
Individual contributions cause redistribution. Did you think charitable organisations or just government?
Yeah, I'm also curious how 8 happened. I think it may have been some institutional committee type effect because it seems to dumb for a smart individual to do. It didn't really effect me because I just skipped 8 but three of my friends / family who don't follow tech bought a new computer unaware of what Microsoft had done and were shocked / horrified to find things didn't work as before. My cousin figured it took him about 100 hours to get some stuff working again and the other two basically stopped using their computers. It was particually painful with my dad whos 80ish and slowing down a bit but who could use 7 but who was unable to work 8. I have lasting resentment to Microsoft over that - the amount of pain and inconvenience they caused their regular users. And for what? I think the brilliant reasoning was if they force people to use a phone interface on their computers they'll be used to that interface and buy windows phones and tablets. That worked out well for them with the recent $7.6 bn write off on Nokia and presumably lots of well meaning employees losing their jobs. At least the new management seem to have returned to trying to treat their customers well rather than inflicting unpopular stuff in a misguided attempt to get more money.
For me this means you have to be able to reason about your code. When you write a piece of code you need to understand what it does, how it behaves and why it behaves the way it does.

It is not uncommon to reveal bugs during code review just by looking at code when the author claims they have tested everything and it works fine. Of course they have missed some test case, but how do you make sure your quality assurance does not miss something as well?

I believe it is cheaper and faster to understand the code, side effects and interactions than to rely only on testing (which is immensely important of course).

In order to grow as a developer one has to understand there is no magic - you need to strive for understanding.

We could use additional "tricks" with cameras too (e.g. physically obscuring the moon and earth for one frame to shoot the stars then mixing it with the next photo) and with the additional post-processing (which would certainly include reducing the dynamic range to be able to show the photo on the screen) get something that some skeptics would think is "normal" but it's not what was being done on the photos presented, as nobody designs that much for features that actually don't bring anything: It would be easier to shoot just the sky in the same direction (the stars would look effectively the same, they are that far -- the satellite is just one hundredth of one AU away from the Earth and Alpha Centauri is some 271 thousands AU away) and photoshop it.
Nice read. I could envision a Hollywood movie on this premise: Denzel Washington, our protagonist is the country's leading hacker / security expert, invited to give a talk. Only that an unknown Russian will crack him handily, stealing some government secrets. Then the movie would quickly deteriorate into gas explosions and "hacking tools" written in VB.NET.
Agreed, a list would be nice to have.

I think it's very hard to say that one metric is key for every product. Teams should think careful about their metrics and figure out what matters most. Retention is not always the key. Think about a dating website for a second.

Personally I feel focussing on growth is focusing an all pirate metrics, but one or two at a time. You shouldn't solely focus on acquisition or activation. Especially if your retention is too low. But sometimes your retention is good enough so you can focus on other things.

"EPIC’s “natural color” images of Earth are generated by combining three separate monochrome exposures taken by the camera in quick succession. EPIC takes a series of 10 images using different narrowband spectral filters -- from ultraviolet to near infrared -- to produce a variety of science products. The red, green and blue channel images are used in these color images.

Combining three images taken about 30 seconds apart as the moon moves produces a slight but noticeable camera artifact on the right side of the moon. Because the moon has moved in relation to the Earth between the time the first (red) and last (green) exposures were made, a thin green offset appears on the right side of the moon when the three exposures are combined. This natural lunar movement also produces a slight red and blue offset on the left side of the moon in these unaltered images."
One rarely sees earth and moon to scale at the correct distance. I think this leads many of us to often have a broken intuition about these things. And while these new images are spectacular, the distance between moon and earth is not obvious here. Look at e.g. [1]. It becomes immediately obvious why the shadow of the moon will only hit the earth rarely (during an eclipse). If it's not obvious, try holding two real objects at the correct scale / distance in your hands and make one throw a shadow on the other.

At scale, if the earth was the size of a basketball and the moon the size of a baseball, they would be about 7.5m apart.

Fixing Performance in the Web Stack
When I was very young, and broadcast television was still in its infancy, a 60 minute network show contained about 50-52 minutes of content.

Today, you can feel _very_ lucky to see as much as 44 minutes of content per show.

Personally, I don't care if they stuff 54 minutes of commercials into each 60 minute show. I'm not going to watch the show as it's broadcast. I'll watch it on netflix, stream it, or download it. In any event, as far as I'm concerned, the commercials never happened :-)
which is why it's so important that netflix can have their own original series. House of cards, and dare devil comes to mind, but they need to do more. Once they break the strangle-hold of studios, and have their own content, they can slowly leverage their large subscriber numbers and fight the studios on even terms. I wish HBO and netflix join forces, because i see them as being more similar than different. But of course, that'd never happen...

We demand actual proofs of program correctness, but for some reason we don't even ask for proofs that practices actually work or even that they don't do any harm.

Testing works extremely well for anything that you either find in the wild or anticipate beforehand.

Hard to find using testing: performance related issues (for which you'll need a profiler), bugs that occur rarely (for instance, one bug I recently uncovered in 'hugo' was so rare it took 1000+ runs of the test software before it turned up on the machine of the lead dev, initially he did not believe my report, see https://github.com/spf13/hugo/issues/1293 ), programmer errors (this is where code review comes in), coverage issues such as routines that are simply never exercised (for that we use coverage tools), errors in the tests themselves, heisenbugs and so on.

Bugs come in many shapes and sizes and testing is a very powerful strategy but it is not the only strategy.

I personally find the "NOMIDDLEMAN" logo hard to read because the words blend together - maybe the word "middle" should be a lighter colour?

On the "How we do it" page, there is some kind of gramatical error in this phrase: "...a product is marked up
many by the time it reaches the customer..."

I'm also not convinced by the explaination. In most cases the supply chain is simply Manufacturer -> Retailer -> Customer, and I don't see how this is changed. The name makes no sense to me because nomiddleman.co is itself a middleman.

People are complaining about the length of time it takes to get treatment, and the cost of treatment, and that treatment is a racket.

All that stuff is true. All that stuff is avoided by losing weight.

Your comment appears to be overly sensitive to a calm, non-judgemental bit of information.

EDIT: Here's the link to the CDC page which lists overweight as a cause of sleep apnea: http://www.cdc.gov/healthyweight/effects/index.html

It's really easy for people, especially men, to hit a BMI of 30 and not realise that they are obese. Especially in obesogenic societies where very many people are obese, morbidly obese or even super obese. This carries a range of health risks, most of which are helped by losing weight.

It's weird the source article doesn't mention weight, since it is caused by lack of sleep (especially in children and young people) and causes lack of sleep (in adults).

http://www.cdc.gov/sleep/about_sleep/chronic_disease.htm

> Laboratory research has found that short sleep duration results in metabolic changes that may be linked to obesity. Epidemiologic studies conducted in the community have also revealed an association between short sleep duration and excess body weight. This association has been reported in all age groups—but has been particularly pronounced in children. It is believed that sleep in childhood and adolescence is particularly important for brain development and that insufficient sleep in youngsters may adversely affect the function of a region of the brain known as the hypothalamus, which regulates appetite and the expenditure of energy

As to what they use it for, they are adults and can make their own choices, whether it be using it to pay for a EduX course ( unlikely ) or buying heroin ( unlikely ).

If you or I became homeless ( admittedly unlikely ) and begged for money ( hopefully unlikely ), surely you would want to be given money rather than fake friendliness or food.

For a dating website retention is extremely important. After all, if the dating website is to be a commercial success the last thing you want with a subscription model is to have everybody use the site once on their trial period and then cancel. Successful dating websites all bank on being able to extend their customer life-cycle as long as possible.

If your retention is good enough (> 98% month-to-month) then you can focus on other things but if it isn't then you're likely going to burn through a lot of cash faking growth when you really should be focusing on why people are leaving and fixing that first before you spend the big marketing bucks.

You might be surprised how easy it is to become overweight without really realizing it.

I slowly gained about 30kg (66lb) in my early twenties (I went from about 75kg to 105kg at peak over about four years). When I started having trouble breathing at night I knew there was a problem (and figured the weight might be the cause), but I didn't hear of sleep apnea until a few years after I had lost the weight (the breathing difficulty disappeared with it).
I can see a whole business built around 'show HN' where you crowdsource input on what you should do to improve a customers website. Just create a novelty account, post a show HN, implement the top voted comments and profit.

Why are you putting such a focus on gender? Why does the assistant need to be a "cute girl"? Do only "female shoppers" care about the difficulty of using furniture? Your advice comes off as pretty sexist to me.
I don't know if this is affecting sales, but you've got some data entry or classification problems.

If you mouse-over where it says "LIVING ROOM", the drop-down menu that appears has something called "3 Person Sofas" in the Sofas section. Clicking that reveals two items.

If you click "LIVING ROOM" and then try to narrow it in the "PRODUCT TYPE" list on the left, there is no such thing as "3 Person Sofas".

The "2 Person Sofas" has similar shenanigans, but the opposite way. It does not show up in the drop-down, but shows up in the left sidebar as a product refinement option.

The "2 Person Sofas" category, which has 1 item, seems to have been rolled into "Loveseats" in the areas where it is not available as a separate category, but this rolling in has not been done consistently, where it is available side-by-side with "Loveseats" the behavior is confusing.

• From the drop-down, click "Loveseats". 6 items are displayed, and the product type refinement options break these down as 1 "2 Person Sofa" and 5 "Loveseats". So everything is sensible here.

• From the drop-down, click the "Sofas" heading. The product type refinements include 1 "2 Person Sofas" and 5 "Loveseats". Fine, and consistent with the above.

• Click the "LIVING ROOM" category, rather than clicking something in the drop-down. Now the refinement options list 1 "2 Person Sofas" and 6 "Loveseats".
What a nonsense. On the technical side, why build this on top of Bitcoin or some other block chain? Why not just a good old database? It does not sound like they are planning to build a completely distributed system and so those companies will be central authorities in some way or another anyway, so why not also host the data?

On the music business side - and I admittedly know nothing about it besides the bits and pieces from articles about royalties, DRM and whatnot you read now and then - it seems totally impossible to me that a small startup would have a chance notably larger than zero to have any large or even transformative impact.

Eyes have about 24 stops dynamic range, there are sensors that have over 20 stops dynamic range with a single exposure, with multiple exposures (HDR) you can of course get way more than that.

The problem is that our monitors have very limited dynamic range - so even if the original had very high dynamic range, it would not show up properly on a current monitor.

There are HDR panels coming to the market this year which have more dynamic range.

And of course it's possible to tonemap HDR images for viewing on normal screens - there are various algorithms for that - https://en.wikipedia.org/wiki/Tone_mapping

> it's net neutral for most companies

My take is that if there were only two companies this would be true. Considering that no company employs more than a tiny fraction of the skilled labour market the vast majority of labour innovation occurs elsewhere.

A company would have to be doing an immense amount of innovation in order to not have a net benefit from free movement of labour.

We could talk about whether the Googles, NSAs, or Amazons of the world hit this threshold, but I'd argue that nobody else does.
