> Mathematically a single queue is far more efficient.

No. In the absence of behavioral effects such as the ones suggested here, the reason to have a single queue is not to reduce the mean time for a customer to check out, but to reduce the variance. With one queue per cashier, if you happen to get behind the person paying entirely with pennies, you're screwed. With a single queue, the additional latency introduced by such a customer will be distributed among all the customers who aren't being served yet, rather than just the few people behind them in the same queue.
I was just stating the outcome in a more negative way. Most had no reversal but also most didn't get worse either. Because half of that 70% were in the "halted" category which might not be much use if you're already at a late stage of the disease and you were only eligible for this treatment because you were almost dead.
What your missing missing out is the societal destruction of the USA inherit in highly polarized wealth in a society. Crime increases with wealth inequality and it's because of companies exploiting visa's like the H1B.

You've seen this crime yourself why would you want to make America crap like the Phillipines?
Rest assured, not all new languages take this route.

On the other side of the spectrum, type systems get stronger and more powerful. Read about dependent typing in Idris, F*. Also, nearly all academic work focuses on improved type systems.

i vote we change the name. "generalized quantum mechanical phenomena maybe" ... and we can rename quantum gravity to "generalized macroscopic versions of quantum phenomena maybe"

then we can add the "maybe" suffix to all the rest of our theories

Babbage designed a computer almost 200 years ago. We need people to be working on moonshots. A lot of them will fail. When one finally succeeds it pierces the veil of "just in time" capitalistic motivation. The financial incentive is certainly perverse in this case. Everyone sells their ideas up front in a frenzied competition to exist. We need a lot more research for the sake of research. More varied and more useless. We need to find a way for people like Babbage to exist, at scale, while seeking whatever intrinsic motivations drive them. We likely won't be able to know if they're doing anything useful until they're done. Academia needs the ivory tower.
Can you point me to the documented cases you are referring to?
I don't know if it's some kind of nostalgia factor (since a lot of old 16-color EGA software used it, I think), but I find ordered dithering output strangely appealing. I have also used it sometimes where size mattered more than style on the assumption that GIF/PNG compression rates would be better on ordered dithers. ImageMagick can do a lot of dithering styles and it's fun to play with.

> Why would one use Algolia over Postgres's built in text search features? Ex: http://rachbelaid.com/postgres-full-text-search-is-good-enou....

Postgres built-in search features are really for large document searching -- we've tried using it for indexing e.g. an array of tags for auto-complete and the search times were in the ~500ms+ range, as a matter of fact the non-indexed regex search was only slightly slower. I thought the later was rather surprising - but asking on the mailing-lists, I was told that this was basically working as intended.

edit: I don't fully understand the value-proposition of Algolia either, most of the trouble with going outside of your production database for search - is the problem of keeping your data in sync and current with the production database; compared to that setting up an Elasticsearch cluster really isn't such a big deal, there are also half-way solutions, for example Amazon has an Elasticsearch-service.
Albeit less featureful than pew or virtualenvwrapper, pyenv[0] is great also.

It looks like pew uses virtualenv-clone[1] internally. However a casual test indicated quite a few shebangs unmodified and in the case of venv, the activation scripts as well.

If one cashier can do the job of 3 and you can get away with paying them 1.5x the salary because you are paying them 1 salary + "commission" why wouldn't you?

I'd say a large bottle neck here is the employee base. If they factored in throughout into bonuses then they could get rid of many employees AND look good while doing it.

Orthogonally agree. I can usually tell when a site's running Algolia by the asymmetry between the quality of the results (useless) and the familiarity of the site (high). It feels like the product is endorsed more for social, versus technical, reasons.

Your original phrase is factually incorrect. Had you said what's actually true instead of exaggerating for effect, you might have gotten a different answer. And about context, question marks and twelve year olds, that's rather out of place and it's exactly what you did with your original phrase.
As far as I understand - according to the article, loneliness in itself is not a bad thing for the health but what it brings with itself - the possibility of depression, possible risk of suicide, inactivity hence possibility of obesity and diabetes. I wonder how it affects the people who genuinely prefer being alone, and like it!
I feel like we're just no longer the shiny hotness. I think a lot of people WANT to be self-made self-taught semi-low-level language programmers.

I listen to a lot of podcasts. My god, I just want a decent show that is NOT focused on web development. Is that so much to ask? Oh, and not ios/windows focused, 'cus then literally everything you talk about no longer applies to me. And not "a new language every week" because my god, you can't deep-delve into anything like that. Hell, not even javascript can be covered in an hour.
That's entirely unsustainable. If enough people do what you suggest, your children will find themselves facing a Malthusian catastrophe with the wrong values to avoid it. It's also quite selfish.

I often can't stand the Apple Store model. I walk in to buy headphones and stand around like an idiot waiting for one of the employees to be free to ring me up. Just give me a line to wait in, please.

This problem has improved significantly in the past couple of years, I imagine due to Angela Ahrendts takeover of the stores, but I still find it annoying.
But it's a useless result.

As a customer I only, only care about my perception of speed, not actual speed.

Multiple lines 'seem' fair, there's also little variance and hence I leave feeling positive most of the time.

A store might save a small percent on cashers using this research but pissing the customers off the huge amount it would seems like poor economics.
This is terribly naive. I walk around my neighborhood saying hi to people and they call me names because I am a member of a number of disrespected minorities. Social cohesion is a much more complicated problem than walking around and talking to people.
I just wanted to add 2 things:

1) Whether you have a disability or not - I have always wondered if I was hired because I was young and could be 'molded' or if I was qualified. Maybe it's at the forefront of your mind if you're disabled, but I'm sure everyone wonders if they got a pass for a superficial reason.

2) It has been my experience that those with a disability overcompensate in other abilities to appear as qualified as their non-disabled colleagues.

Basically, you have three components of the future organization that get "architected" early on - how it sells things(marketing, sales, support), how it makes them(engineering, manufacturing, services, etc.), and how people in the organization are treated(hiring and management). These things need a design to them, or at least a rough strategy, and they have to cooperate in some way. Once you have a design in place, then you have your work cut out for you.

It is possible to make viable businesses by leaning on any one of those three elements. You can find the anecdotes: "I sat in my basement making weird computer art and it turned out internet people fell over themselves to get their hands on it", or "I pitched something that I made up while in the waiting room and they funded me to make it", or "We were a bunch of talented school friends and decided to go into business together without knowing what the business was". Those are all at the extreme ends. A balanced approach is also possible - you make a little bit, then you try to pitch it to some people, then you try to convince people(perhaps even the same people you pitched to) it's worth working on. Step by step you go from "we don't know what we're doing or know what's going on or who should work on what" to "we've solved all the major questions of this market and have a team that delivers good value."

The way in which you execute on these plans should ideally stay in line with how you feel comfortable doing business - your philosophy, your ethics, your motivations, etc. There are plenty of ways to cut corners and do wrong, or to try to lead when you aren't actually a good fit, and this may stop you from pursuing an otherwise worthy concept. Entrepreneurship isn't a job title or even necessarily about business so much as it is an extension of the act of poking at things and people and seeing if it gets some gears turning.

So, in any case, the validation is good, but the most important thing a company needs to continue operating is to close deals - hence there's always an undercurrent of "build up your pitch, build up your leads, product later" to a lot of biz advice. You know you can execute on the technology again - you already did it once - so that's not a big issue, as long as your technical ambitions stay in line with the original work. But progressing on the sales front is a big deal, and with the client work you're at a generous "0.5". A clear next step is to distill everything you learned from working on it into a better, more saleable pitch, and build up contacts and leads. You may want to get someone already in the industry to do some of this work, but at no point can you expect to be completely hands off.
It really didn't. Universal is flat out wrong unless you're using the exact same code on both server and client.

Isomorphic is 100% correct if you use the definition from biology, crystallography, sociology... etc etc. It's more technical of a term in one single field. In every other way it's a perfect description.

* Sociology: a similarity in the processes or structure.

* Crystallography: two structures closely similar in shape, formulation, and structure.

* Biology: a similarity of form or structure between organisms

All of these more closely describe a JavaScript application that lives on the client and server - because while they will be similar the likelihood of them having the complete same code (and therefore being universal is minimal.
The additional tax paperwork/filing burden and the fact that very few banks overseas will open a bank account for a US citizen (due to FATCA) are still not worth it for a lot of people.
Honest question: if a guy in India can do the same job as a guy in the US, but coming from a country with worse economy agrees to do it cheaper, why would I sympathize with the american guy in this situation?

Honestly, to me it seems like american working class have been really privileged compared to the world's population in 20th century, and globalization finally brings some equality — which might not be a good thing to american middle class, but is a great one for workers from China, India and all other 3rd world countries.
Same experience here. I stopped going to Apple Stores because the experience was so stupid.
THANK YOU.

Sometimes I feel like I'm taking crazy pills because "universal" isn't and "isomorphic" is not only technically correct - it's absolutely accurate for the relationship between client and server side code.
Yikes. I hope your situation is the exception not the rule.
It doesn't always work, but if you don't try it always doesn't work.
I feel this is an instance of Flanderization [1]. There are definitely some differences between France and the US, but they get blown out of proportion. And this is not specific to France, other articles take northern countries as the golden examples, or Japan, or China, by focusing on one particular aspect.

On the other hand, it can be good to keep in mind that other models of society can exist, even though they may not be exactly realistic.

You don't understand isomorphism outside of a very very very narrow usage of the term. Especially how it is applied here.

This is false. Per capita, violent crime (especially homicide) rates are higher in urban than suburban or rural areas. There is a ton of data on this, and it isn't close or even debatable. There are other factors (accident rate) that can make urban areas look safer, but not violent crime.

The FBI reports the 2011 rate of violent crime known to law enforcement within metropolitan areas was 410.3 per 100,000 persons. The rate of violent crime per 100,000 persons in cities outside metropolitan areas was 382.1, and for nonmetropolitan counties it was 186.1.1

The FBI reports metropolitan cities had a murder and nonnegligent manslaughter rate known to law enforcement of 4.9 per 100,000 persons in 2011. Cities outside metropolitan areas had a murder and nonnegligent manslaughter rate of 4.4 per 100,000 persons while non-metropolitan counties had a rate of 3.1 per 100,000 persons.

I live in an area of Shenzhen under massive construction (like much of China). Surrounding my apartment complex on three sides are constructions projects filled with many thousands of migrant workers- all male. They will be working on the project for at least six months before they can go home. Shenzhen has modernized- so has no real “red light district” like it used to or some Chinese cities still have. There is no chance these men can have sex for at least 6 months. When they go home there is a very good chance they still will not be able to have sex since most young women have migrated to the cities. These men are all very polite. I have never experienced anything worse than a shy smile. How long will that last for?

Of course a meal made by a wife tastes best, a husband who carries your bags most romantic, a true lover- of course, but Chinese have to be realistic due to our circumstance. So are very, very interested in automating some forms of manual labor. This technology is spoken of all the time. We have few other options if we want to keep a stable society. Most of those options are not very good for women.
I think the point is that this kind of article tends to present it as uniformly better, rather than contrasting the good and the bad.
Isolation is so painful; it's literally traumatic for people. You are not at all the only one; in fact, what you are experiencing is a perfectly normal reaction. Humans are fundamentally social beings; without other people to socialize with, our cognitive and emotional systems don't function properly. For example, for children, I believe it's well established that even abuse by parents is better for them than abandonment. A much more extreme example is people in solitary confinement, who experience serious mental and emotional problems due to their almost complete lack of human contact (beyond anything even isolated people experience out in society).

Your social skills and energy will return naturally when you feel better. Consider finding a good therapist who you feel comfortable with. Not only will you have someone to talk to, but they can help you understand and manage your problems and help you develop the skills to do the things you want to do.

I would love to read on HN someday that it worked out well for you. Take care.

Nobody is suggesting that a single rape demonstrates the existence of rape culture. However it does mean that you cannot rule out rape culture, whereas if there were no anecdotes you could reasonably claim that there was no evidence.

The fact that you have to use extremist examples and insults, suggests strongly that you know you can't make your case.
This is simple "they stole our jobs" rhetoric. It's just like taxi drivers with their "Uber stole our fares". If you can't compete, go to another market. If you're already overcharging, charge less. "Depressing local wages" is a good thing - it reduces the cost to society of getting productive things done.

The other argument about foreign workers being exploited is a clear sign of people pretending to care but really not caring. Sure there are some who were tricked into debt traps, but for most, they know what they're getting into and they know it's better than what they have back home. So they're making a step up in life. You want to kick them back down because you care about their welfare? What it means is you only care about people in America and once they leave, they lose their status as worthy human beings who deserve good working conditions.

I used to be a foreign laborer. I was paid minimum wage to do grunt work that locals didn't want. It was wonderful. The currency was worth more in my home country than where I was working. It helped me pay off my student loan. I would have hated to be forced out by someone trying to protect me from myself. My coworkers loved it too, they'd send money home to help their parents run their farms and pay off their own loans. They'd laugh at the lazy local workers who were mostly overweight and doing the same job more slowly.

Makes sense. Kids learn and mimic, they structure your life around you. If you then go and structure your life around them, you end up in a loop that amplifies random noise.
It really is a very wrong use of "isomorphic", though:

First, "isomorphic" is a word that denotes a symmetric, relative relation between two separate things; Two things can be isomorphic to each other but one thing cannot be called "isomorphic" without specifying what other thing it is isomorphic to. That simply doesn't make sense.

Second, isomorphism is about those two things having the same conceptual structure, despite being different things. In math, this means that you can define a lossless two-way conversion between the things (you can start with an A, turn it into a B, and go back to an A, and you'll get the same A). In biology, the field the author took his definition from, isomorphic means that the things have a different ancestry but the same structure. This is literally the opposite of taking code and shimming or compiling it to allow it to run in multiple environments, as it would be taking a single common ancestor codebase and lossily changing its structure to allow it to run in multiple environments.

edit: Just realized you are the author. Now I feel silly for referring to you in the third person. In any case, I do want to say that despite any squabbling over terminology, you seem to be doing great work in putting out rill. Developing a full-blown application framework like this mostly on your own is no mean feat. My squabbling stands, though.
