> If there is an equal increase in upper class population for every loss of middle class population, that just means that our incomes as a population are increasing

If they were defining boundaries by inflation-adjusted income, that would be correct.

They are defining them by ratio to the median income, so more upper "class" at the expense of the middle "class" by the standards used just means increased income inequality, not increased real wealth. (It could accompany increased or decreased real wealth, but its a completely separate thing.)
I can't get past the fact that the software, in order to interact with the 3D world, will be expensive and cumbersome to make. Also, people (your income) born before AR tech generally don't want hardware on their face.

This, and Hololens, and similar, will fail for a while, and I'm thinking it will be decades. I'm placing my bet now.
It can depend, though of course genetics are probably a factor. I had sealant applied when I was a teenager, but never since. I'm now 38; still - at least, as of my last dentist visit a couple of months ago - no fillings.
Since you're an expert: what about these videos is hard? The things that jumped out at me are:

1 - the robot moving behind the table leg (ie you have to do depth recognition of objects in the scene)

2 - the user's hand interacting with the artificial elements in the scene. Some code had to recognize a hand and figure out which element it was touching.

What strikes you as the hard parts of those videos besides the real-time requirement?
The original author never mentions the word "valid" in regards to moral motivations. Trying to define what would make a moral motivation "valid" seems quite difficult.
> Perhaps they get around that valuation with 100M/year in patent licensing.

Patents expire after 25 years, so at 100M p.a. deal for investors is spend 1B to get $2.5B back, two decades later. I'm not sure that even beats fixed interest.
Even with continuation it's still around 10% return.

I'd have to check _Albion's Seed_ for the details, and how their penal code compared to England's and their neighbors' -- but isn't it obvious that there's a contradiction between "preaches mutual love and respect" and "flogs people"?

The Quakers were perfectly capable of innovative thought, and of thinking through the consequences of their principles (thus relative sexual equality, concern for animal welfare, and encouragement of vegetarianism); but they were fine with using brutal violence against anyone who didn't accept their doctrine of nonviolence -- especially those from different cultures, and followers of different religions (or different Protestant denominations; they were particularly cruel towards the Presbyterian Scotch-Irish). This is why they get under my skin.

This is going to be an especially hard problem to tackle, because you have liberals that want to say morality is just a social construct, and you can't say anything is good or bad, while you have conservatives that want their morality channeled through a doctrine that's hundreds of years old.

We need to pick ourselves up from our bootstraps and say morality is tied to the well-being of any conscious system and there's a landscape where you can navigate more 'right' or 'wrong'.
Given the title and intro, I expected information useful for people not using the app. Skimming the article didn't yield any, I was wondering if I should bother reading the article if I'm not interested in their app.
Of course the concept isn't radical. The difference is that it is suddenly a scalable business.

At the moment the per-unit cost of per film is constant. If software "composes" the music then the per-unit cost drops with each additional user.

That's the radical thing.

Taxes are a cost of doing business, and yes, businesses will optimize that cost wherever they can, but paying 1% less in taxes isn't a bargain if it increases your costs or lessens competitive ability elsewhere.

TL;DR

"Finally, on the special Chimera instances with the tall, thin energy barriers, the authors find that the D-Wave 2X reaches the global optimum about 108 times faster than Quantum Monte Carlo running on a single-core classical computer. But, extremely interestingly, they also find that this speedup does not grow with problem size; instead it simply saturates at ~108. In other words, this is a constant-factor speedup rather than an asymptotic one."
This is a good point, I think the better point to make is that when you have a big company that's been around a while there have been a lot more opportunities for things to go wrong, which leads to unhappy current or former employees, and then bad reviews on sites like glassdoor.

A company like Airbnb hasn't gone through like 1/100000 of the pains that Google has gone through. Think of all the products Google has built (some successful and some not), think of all the economic environments Google has had to go through (2000 meltdown, 2008 meltdown), think of all the employees who have worked there (there's 60k now, but google has probable cycled through 5x that amount).

Airbnb has made like, one product? Through a relatively small stretch of time, while probably still using most of their original employees. It's an electric time to be at Airbnb no doubt, but I wouldn't trumpeted them as the best place to work just yet.

Why Caramel? Why not just Lisp/Scheme? for the example.

Funny you should ask this question on HN. Have you read PG's essays on Lisp and the competitive advantage it granted his team in developing ViaWeb?

Your question might be about PLs, but in effect you are asking why somebody would prefer one abstraction over another.

Personally, I find it difficult to read and grok math. But if I write out stuff in Lisp s-exprs and use meaningful names for functions, etc, then I generally can understand a little bit better. Being able to "execute" such descriptions helps further.

Languages such as Lisp, Scheme, Smalltalk, Self (of the ones I'm familiar with) have simple syntax and powerful abstractions. They failed to gain "market share" due to perceived failings. However, they adhered to the philosophy of Occam's Razor.

I'll probably get flamed for saying this ... when you look at systems written in Lisp, the debates tend to boil down to people arguing over whether their abstraction is better than the other guy's. With a powerful language you can do anything in any way you choose. So the abstraction becomes the differentiating factor. Hence the emergence of not invented by me syndrome.
> Well, then it doesn't much matter which definition of merit (who is better) you take

Yes, it does.

The definition of merit is necessary to assess whether the current system is, excluding AA, actually meritocratic, as claimed. While it would also be necessary in order to assess whether one race or another was better than another, if that were an interesting question to answer -- the fact that I'm not asserting that one race is better doesn't alter the fact that an actual definition of merit is necessary for the claim that the existing system (but for AA) is meritocratic to even have meaning.
Yes, that was I was expecting.

That's discussed pretty well in the article. The headline is a bit extreme, but the article is not.

The problem is more one of polarization than average wealth.
Roman numerals did not have a zero. It could only be used to represent counting numbers between 1 and 3999. As abstraction s go it failed to accommodate a large number of situations that Arabic numbers could.
You park your capital somewhere because you like the commercial, legal and financial infrastructure. Insofar as your financial mass distorts economic spacetime for everyone int eh vicinity, it's not unreasonable that you will be asked to pay some of the costs of said distortion. If you stay in a hotel that's only half-full and make your bed before you check out, would you expect your stay to be free? Probably not.

I'm being a bit tongue-in-cheek here, but your repeated claims that taxes are too high presupposes some objectively correct level of taxation. In the real world, what happens is that tiny poor jurisdictions set tax rates that would be economically unsustainable but for the prospect of attracting some huge international firm whose revenues are so big that even a tiny percentage of them is a lot of money for the poor jurisdiction, and the extra administrative costs of domiciling the corporation there are less than the difference between the unusually low tax rate and that of a more economically logical place for the headquarters, based on actual factors of production.

Why should taxes come down to the level of whatever the poorest country is willing to charge in order to attract itinerant capital? Why not (as we are sort-of in the process of doing) just deny market access to firms that don't want to pay prevailing rates?

It's not that I hate capital as such, but as an individual I have to pay some sort of taxes and my international economic movements are somewhat restricted, because of the basic fact that people can impose costs on an economy as well as contribute to it. I'm not enthused about paying taxes on the income I receive in return for my work product, but I recognize that there's a quid pro quo here as I prefer to live in a civilized society and transact business using money rather than live in a cave and subsist on fish or something. I don't care for the idea that having a large sum of capital should exempt one from these rules, in addition to the obvious economic advantages that said capital provides (and which I slightly envy but do not resent).
Once you get data races in Go, you realize that immutable data structures are indeed the right way. Too bad though. That non-threadsafe, racy map is your only generic data structure.

I think that critics are generally cutting way too much slack to Go. Its a horrible language - with a decent library and excellent tooling and documentation, but still quite horrible.
Unfortunately, that ship sailed years ago. Also, NVIDIA is heavily investing in deep learning (cudnn), so this won't happen unless someone in OpenCL builds something equally/more performant.
People above are right about parallelization not being a useful benchmark.

On the other hand, benchmarking against other special purpose hardware (like an FPGA, ASIC, RQL, etc.) is definitely of interest.

Surely binary is simpler than decimal, and yet humans rarely use it. Purity is nice, but there's a tradeoff with needing to get stuff done so you can pay the rent.

My thought exactly. This is just a scale that can be solved either way; when you really can't fit your data on even a handful of machines with acceptable performance, then Cassandra can start to shine.
It's true - black people tend to underperform relative to their SAT.

http://www.mindingthecampus.org/2010/09/the_underperformance...

Your source agrees with this if you scroll down to the data tables. Note the sign on the black and hispanic coefficients.

So your real critique seems to be that SAT is unfair because it gives a non-predictive boost to blacks and hispanics. Consequently, if we wanted to have the most accurate predictor possible, we'd include negative weights for black people. Is this really the critique you are making of using SAT and GPA?

One of the many reasons for admissions preference for traditionally disadvantage groups is advocated is that many of the measures used as signals to admission disadvantage those from traditionally disadvantaged groups...

That's simply incorrect. If it were true, then blacks would overperform relative to SAT rather than underperform.
When you point out the importance of context, I would hasten to add that for me comments in programs provide context that even the best naming convention, etc fails to provide.

Could you please briefly explain why NoSQL is superior for TB+?
Absolutely. Here's a lifehack for when a small new cavity that doesn't even hurt (much, yet) is discovered --- for some 2-3 months:

- cut out all sugar to the best of your ability,

- cut way down on mineral leeches such as phytates, lectins, gluten

- consume plenty of meat, grassfed butter and liver -- all 3 matter here

A neat easy to follow little protocol for remineralization and overall tooth (and bone) hardening.

In a way it's not as convenient as getting a drill for 20 minutes and heading back to the office donut party or the birthday cakes your friends were sharing. It really is about priorities here. Our bodies are in no way incapable of splendid regeneration at any age, the problem? They take a lot of time, and require "the right building blocks", which really are a bit tricky to find out about, and lastly modern diet interferes severely. Yes, somehow the preformed animal Vitamin A from liver does the trick and so does preformed animal Vitamin K2 from grassfed butter where synthetic formulations or plant-sourced supplements don't seem to. Plus the completely-absorbed and readily-utilizable minerals and amino acids from your meat. Don't blame the messenger ;)
Yeah, that's pretty much my point. $1B might solve the technology problem, but no amount of money will solve the market problem (which I suggest Magic Leap, and hypothetical flying cars, don't have)
Even adjusting for cost of living would be a good start to making this more useful.
I visited Airbnb's headquarters this past summer, and they are very impressive. For example, their conference rooms are themed off actual listings. So you have the African hut meeting room, the elegant Milan room, and the tiny Japanese stress relief space. On top of that, their hallways tell stories. For example, one describes the origins of their logo in beautiful, exquisite detail. Overall, I have yet to see a more creative workspace.

It doesn't matter in this context.

Their conclusion is that in big O notation, quantum annealing and best classical algorithms are the same.

Parallelization would get you a factor 1/k (k being the number of cores) in favor of the classical algorithm at best, which specialized hardware would give you a constant factor boost without affecting the big O characteristics.

The problem is not "which is faster given a fixed n". Quantum computers are interesting for certain problems when n becomes larger and larger.

The real issue is whether if there is an exponential difference between quantum annealing and classical algorithms or not, in big O notation.
Remember, that is the reason why people are so interested in quantum computation. Not some constant speed up.

O(f(n)) vs O(log(f(n))) and O(f(n)/k) vs O(log(f(n))) are essentially the same in terms of their capabilities of solving NP problems.

> With each show generating it's revenue stream, we'll have a lot more variety of content because a show doesn't have to reach the widest audience, only an audience large enough to bring in enough revenue to cover the cost of production.

Except each show will still have to reach the widest audience, because it will have to bring in more revenue than the entity producing would expect from the best alternative use of the same input resources, not just enough to break even.
Did you read the article? It isn't saying that at all.

Even the introduction clearly explains that it is addressing a trend of developers using NoSQL because of hype rather than actually evaluating their use cases, and that the remainder of the article is how Wix found MySQL better for their specific scenario. They even give tips on when to know if MySQL is good for you for this use case.

It does not attempt to make sweeping statements about NoSQL or MySQL, nor does it prescribe a solution for every workload.

I cannot comment on its horizontal scaling.

I can say however that Postgres, from what I understand, has nearly linear SMP vertical scaling up to 64 cores. There's an awful lot of headroom there. I read a long while back Jeff
Atwood saying that StackOverflow ran on a single vertically scaled database server with MSSQL for a long time.

If I needed to go beyond vertical then I'd maybe horizontally scale in a custom manner based around the application data access characteristics, which plays a huge role in designing sensible horizontal scaling solutions.

If we compare single core CPU performance against heavily motivated special solution, then it is not (it does not follow that the same method can be applied in this case, but then again, a better classical algorithm on single core beats the reported quantum result according to the paper (PS. this is in the paper, not on the graph)).

Here is comparison http://bitcoin.stackexchange.com/questions/36412/what-is-the... between GPU and ASIC bitcoin mining and here is https://en.bitcoin.it/wiki/Non-specialized_hardware_comparis... GPU and CPU comparison.

From this the difference between between GPU and ASIC solution is about 10^4.

Google tested against Intel(R) Xeon(R) CPU E5-1650 single core, so it would be roughly 10^2 slower than GPU.

So one could say that ASIC solution for bitcoin mining is about 10^6 times faster than single core CPU solution.

Million times difference is of course not 100 million times difference, but it is still a lot and then again, alternative classical algorithms would beat current result: Based on the results presented here, one cannot claim
a quantum speedup for D-Wave 2X, as this would require
that the quantum processor in question outperforms the
best known classical algorithm. ... This is because a va-
riety of heuristic classical algorithms can solve most in-
stances of Chimera structured problems much faster than
SA, QMC, and the D-Wave 2X (from http://arxiv.org/abs/1512.02206).

I think that this is an important and an interesting result, but it is in my opinion not that impressive that it may appear to look.
