No explanation of how they do it and:

Internal studies show Opternative’s exam performing equally to a traditional refractive eye exam. Before launch, we will conduct a third party NIH registered, IRB reviewed clinical study and be in compliance with the FDA.
People grow out of it? Seriously? I don't like seeing addiction only in the traditional way of hardcore drugs, alcohol, etc. There are loads of addictions that aren't even recognized by doctors as such, but are quite far spread. Most of all cigarettes (I don't know any person who gets treated for cigarette addiction), sugar, gambling, virtual realities like tv shows or digital games. In Germany I feel over 50% of the people around me smoke. In nerd circles around me over 80% of people are addicted to either sugar, caffeine, or gaming. In my family I even have 2.5 cases of serious alcohol addiction that is neither treated nor recognized by the addicted. And I live in a middle class family. In lower class families it might be much worse. Maybe I misunderstand the article, but I think saying that most people grow out of addiction is way off reality. I'd argue most people on this planet are hooked to at least one thing, and nearly nobody drops their addictions.

I personally are certainly addicted to sugar. If I don't get my coloa/chocolate/icecream, I feel tired, hungry, sad, and am sometimes in pain, can't think about something else but sugar, and sometimes even walk long distances in the middle of the night in the worst of weathers to get to a 24 hours shop to buy something, if I don't have something at home. Telling this to doctors just yields them saying I'll get diabetes (or might already have it) if I don't change my behaviour, which is pretty much what I already know. Requesting general addiction treatment or food advisory training is not covered by my health care, they say.
I'm guessing this isn't a coincidence, with osx yosemite out as a release candidate?

Quite simply: The ability to move between social classes.

Social mobility is the movement of individuals, families,
households, or other categories of people within or
between social strata in a society. It is a change in
social status relative to others' social location within a
given society.

I'm not talking about mental limitations surrounding perseverance. I'm talking about mental limitations surrounding my talent at drawing.

Take music. It is documented that approximately 4% of the population suffers from what is described as "congenital amusia", commonly known as being tone deaf. From the Wikipedia article on the subject (http://en.wikipedia.org/wiki/Amusia#Congenital_amusia):

"Individuals who suffer from congenital amusia seem to lack the musical predispositions that most people are born with. They are unable to recognize or hum familiar tunes even though they have normal audiometry and above average intellectual and memory skills. Also, they do not show sensitivity to dissonant chords in a melodic context, which, as discussed earlier, is one of the musical predispositions exhibited by infants."

Now I'm really good at music. From an early age, the things that are hard for congenital amusiacs came easily to me. It was really obvious from an early age that I was good at it. As a result, I've spent at least 10k hours of my life doing music and achieved a high level.

It makes no sense to me to say "well how do congenital amusiacs know that they won't get better if they just give up?" Without some extraordinary evidence, it is not reasonable to claim that if a congenital amusiac just spends 10k hours, they will become superb at it.

The reason I didn't spend much time drawing is not because I generally lack perseverance, it is because it was extremely obvious that I am not talented at it. I know this because I know what it feels like to have talent at something.
I didn't thought about it, but you're probably spot on.
The problem isn't geography, it's management. And the question becomes, why San Fran? Why burn through that $50mil in a week? It's an arrogance move. San Francisco isn't the center of the world. Why not relocate to a low tax state, perhaps Austin? It's just nonsense to suggest that 'remote isn't working;' it's obviously working well enough that Reddit was able to raise 50 mil.
The physical servers used in clusters I buy today run about $4k per server without storage. Outside of the dual 10 GbE interfaces, they are like most other budget servers. Storage costs per node vary depending on the size, type, and mix of disks. Driving the disk I/O at 10 GbE can be trivial with a good I/O scheduler design, so ironically the details of the storage device are almost irrelevant for many workloads. Cheap SSDs are the default target but cheap spinning disk works surprisingly well for many workloads.

Various AWS nodes are also used in clusters quite a bit (though we use ephemeral disks rather than EBS). Nothing exotic.
Oh man, that just made me realize my 9 year old dog doesn't have a lot of time left probably. It's weird, she doesn't seem to behave any differently than say 4-5 years ago, and still has lots of energy and zero health issues. So I just don't think of her as being old. According to these charts she's 55-60 in human years.
Coolblue - Rotterdam, Netherlands (relocation offered) - C# Developers of all levels

We need awesome .Net developers!

We are in the process of a monstrous migration to C#. The application concerned is Vanessa, and Vanessa is big and complicated. We are not just migrating it, we’re building a completely new C# CRM meets ERP application from scratch. So no legacy code in our C# ;-). To do such a job in a very good way very very very intelligent developers are key.

Coolblue is: no hierarchy, crazy obsession for testable code, max intellectual freedom, growing ridiculously fast, loads of fun (we have our own gaming arcade and bar) and not to forget great technical expertise!

We're doing good, very good: we're an award winning company and we've set the standard for e-commerce in the Netherlands.
To be able to stay the best, we need the best. That's why I'm posting.

More specifically, I'd say that the Nokia 3210 [1] was one of the most iconic and recognisable mobile phones. It was the one that came with Snake and created the fad for comparing high-scores amongst friends.

A simpler way: Look at what big tech company x is doing that looks to be selling. Do they use an open source solution to it if it is software based? Do they provide a api or something that could be useful? Is there a market for an addition built on their framework or is it based off of an open source implementation which can be improved?

If yes to all above then you can maybe turn that into a product. A great site for seeing what is available for frameworks is yeoman: http://yeoman.io/generators/ .
As an NLP researcher, I see lots of NLP papers on top of AAAI. I think that the high citation count is due to

(i) people in NLP actually bothering to tell others why their approach is interesting

(ii) other people being interested in the same / a similar kind of thing [avoiding the discipline-of-one problem that niche AI applications would have] and

(iii) NLP having a reasonably developed "canon" about what counts as must-cite papers. This canon is heavily biased towards US work, and towards people who write decent explanations of what they do, but at least it makes sure that people know about the big problems and failed (or not-quite-failed-as-badly-as-the-others) solutions.

What you see in other conferences is that the "Best paper" awards get to (i) more theoretical papers which still have issues to solve before people can use the approach (nothing wrong with those!), in (ii) subfields that are currently "hot". Whereas the most-cited papers are (i) more obviously about things that a dedicated person could apply in practice, and (ii) in a subfield that is obscure at the time but will become more popular in the following years.
It depends where you lived. In Europe the Nokia 3310 was king, but in Japan clamshell were all over the place.
That article, expanded, would make a fantastic, fantastic book, if done properly.
How do you bootstrap a company that requires significant R&D before an MVP can be shipped? Or for that matter one that has initial infrastructure costs, or one would only be affordable if there's an economy of scale?

This is armchair quarterbacking, of course, I'm not an entrepreneur and do not pretend to be one. Patio11 has a lot of interesting and relevant things to say, but I would hate to live in a world where entrepreneurs only undertook ventures that could be bootstrapped for a reason that I'll frankly admit is selfish: throughout my career I've worked on very fascinating problems in either VC funded startups or companies that have began their life as such; I can't see a scenario where I would have been able to do this (or similar kind of work) in a bootstrapped product company. That's not to say there aren't other interesting problems that could be solved in a bootstrapped company, but my own area of focus -- distributed systems -- is almost by definition something that requires both infrastructure and up-front development (and, in general, is only something that should be used if there's a scalability or reliability problem to start with.)
I think for those superusers mentioned in the article the invested energy surpasses the benefits and biologists have a word for that too.

Do you think you'll have enough time to improve on the documentation and plugin APIs in LT?

Whenever I've used it I've felt like a small amount of effort in those aspects will allow it to continue to progress in the hands of the plugin community.
Agreed. A single chart clearly illustrating the point you are trying to make vs. an interactive do-hickey that I have to twat about with and then infer meaning from, IMHO shows a huge disrespect for time of the audience. After all, its the authors responsibility to communicate their ideas clearly and effectively; no one is entitled to an audience. I wish more documents/spreadsheets/presentations understood this.

As someone who works in this field, there actually are government standards and working groups that involve all the vendors. I'm talking about in the U.S. - Europe has a much more varied ecosystem and standards appear harder to agree upon. In the U.S. the standard is the Consolidated Clinical Document Architecture (C-CDA)(http://www.healthit.gov/policy-researchers-implementers/cons...). The government body involved is the ONC (Office of the National Coordinator)(http://www.healthit.gov/newsroom/about-onc). The only problem at the moment is the finalization of the draft proposals and the vendor-specific interpretations of the standard. It's getting there but obviously the details are slow to work out.

Ask HN: Education system structure in different countries
I am working on an app about listing colleges and universities all over the world. I found that there is different structure in different countries. eg.

India : There are Universities . Universities has many affiliated colleges. Then there are autonomous institutes. There are polytechnic colleges which doesn't come under any universities.

in USA : There are universities which has different schools/department which are mostly on same campus.

UK has a bit similar structure to India but other European countries have structure similar to USA.

There may be different structure in Africa , Australia, Arabic countries, South Asian countries etc.

How can I find information about this ?
How do you bootstrap a company that requires significant R&D before an MVP can be shipped? Or for that matter one that has initial infrastructure costs, or one would only be affordable if there's an economy of scale?

You can't. That isn't a problem though. The 'bootstrapped versus capital-backed' dilemma is false. It's not a case of one being better than the other so much as a case of "the one that's best for the business and its founders". Often there won't be a choice - some businesses have zero chance of raising money before they start and some have zero chance of starting without raising capital first. The discussion is usually around whether or not the majority of SaaS startups need to raise money first rather than any business.
It's only a rule of thumb. Our Huskies (large dog) generally lived to be 15 to 17 years old. That's about 100 in human years according to the chart at the bottom of the article.
I was super excited to hear this, but how are they going to check for cylindrical + axis defects? Is it even feasible? Or is the recommendation to visit an eye doctor every two years supposed to cover that?

Edit: Their disclaimer at the bottom says:

"Opternative’s technology is only intended and suitable for use by licensed eye care professionals to perform online refractive eye exams on patients between the ages of 18-40 and in good health."

I am now confused. Is it for self testing or not?
20-sided dice, bro.
Are people without existing issues with their eyes actually visiting the optometrist with any regularity? Every two years? That seems weird to me.

Surely eyes aren’t like teeth and need to be regularly inspected. Maybe beyond a certain age and with pre-existing conditions, but otherwise?

That’s more frequently than I go to the doctor for a general health check-up!
My vet actually had the 15, 10, 4, 4... etc chart on the wall.

It still seemed petty when that "biggest gap of all" has a monetary value of about 20 bucks a week. For a higher education, mind you. I am willing to bet that the average student tends to spend more over the weekend in various nightclubs.

And that just made me wonder if they really value their weekly nightly outing more than their own education. I came to the conclusion that it just came down to something like "But the generation before us didn't have to pay. I don't want to pay also".

Also, if these fees were to be used exclusively for investing in infrastructure for higher learning, the students would profit from this. With fees like this is it of course easy that they get funneled into other funds but originally, these fees, small as they were, were supposed to be used to make upgrades in the universities. You'd think students would like to use better equipment. Because now, that they pay as little as their parents did, namely nothing, they probably will also get to use the exact same equipment their parents used.
pg wrote, "Batch after batch, the YC partners warn founders about mistakes they're about to make..."

My question would be "what are the mistakes"?

It would be amazingly interesting if PG, Sam or someone else from YC can start to list some of these warnings / common mistakes in one of the classes.

Obviously, some advice is company specific, however starting to compile this list of advice would be a valuable additional to community knowledge.
I wish there was a bit more to the explanation, like examples of the naming issues listed.

I've found that coffeescript prevents whole classes of bugs, and makes lots of javascript warts nicer to live with.

For example, you don't seem to run into scope issues, and it's a lot easier to bind this to what you expect.

5% more code (if it really amounts to that) is still more code, too! No code is like no code.

"How do you bootstrap a company that requires significant R&D before an MVP can be shipped? Or for that matter one that has initial infrastructure costs, or one would only be affordable if there's an economy of scale?"

You can't — obviously. And folk like Amy Hoy @patio11 freely admit that.

The key word there though is "requires". I've encountered lots of companies that have spent silly amounts of money, often their investors money, because they've missed opportunities to validate their business model in cheaper ways. Either because they don't know how or they don't want to. Folk who are so focussed on the vision that their aiming for that they fail to look down as they walk over a cliff.

To stereotype slightly I'd say that folk with a dev background are more likely to go that route than not — since the business / marketing / user research end of the skill spectrum that can help with that stuff is less familiar to them.

Nothing against VC funding, and it's absolutely necessary for some companies. It's just that the majority of folk that I see trying for it are doing so before it is actually required. Either because they're missing ways they can continue more economically because they lack the skills, or they hope that the (lack of) positive feedback that they're getting so far will be solved by money.
