last I read was they were getting into silicon photonics manufacturing. Sounds expensive, and very patentable.

Would be great if someone with better knowledge would expand on the engineering challenges they face.
The question is can they still say that when D-Wave reaches say 4,000 qubits? What I'm asking is will classical optimizers and classical computers always be able to be "roughly as fast" as D-Wave for that work, or will D-Wave inevitably surpass them by orders of magnitude in future iterations?
How can one know that this message is from Satoshi?
>article ... assumes morality is relative

I didn't get that from the article. The author seems to have looked at how people justify violence and found they gave moral explanations. Whether their morality is relative or absolute doesn't seem that important to the argument.

I think you're missing the whole point for "ShowHN", which IMHO is really valueable,worthy comments/opinions you should take into consideration.
Well. That is the end of that. It did seem pretty unlikely that a rather disheveled dude that seemed to have pretty bad opsec would be Satoshi.

I remember the days of the Athlon X2 versus the Pentium 4...AMD was truly the king back then. Combined with nVidia producing an awesome AMD chipset (nForce), they were glorious days. Then AMD went weird and starting focusing on these dual-socket platforms instead of just improving their stand-alone CPUs...the Intel Core came out...and the rest is history. Sad really.

Later (~2006) I remember because the Athlon X2 was produced in limited numbers, and the eBay price went through the roof as people were trying to upgrade from single-core without replacing every other component in their system to jump to Phenom.

Got in touch with a friend last night who is one the Bitcoin inner circle and he said the PGP key used a different hash algorithm than the real Satoshi and it's a hoax. That was a good twelve hours before that story was in the press. I have a feeling if the inner circle doesn't know for certain who Satoshi might be they've got a pretty good idea.

Mathematically, this is in the land of linear algebra (complex vector spaces.) The particular question at hand concerns the spectrum of a (Hermitian) linear operator, known as "the Hamiltonian". The "gap" refers to a separation in the lowest two eigenvalues ("energy levels") of this operator.

It seems plausible that one could easily encode a turing incomplete problem into linear algebra (think of tensor networks, constraint satisfaction, etc.) but what these guys have done is place very strong restrictions on the form of the linear operator (in jargon: two dimensional, nearest neighbour interactions, translational invariance). This now comes near to a class of physical systems that one may hope to build, or at least understand theoretically, and the result of the paper puts a stark upper limit on what we may hope to achieve in this vein.
It could have been signed with Satoshi's PGP key.
I disagree. Names are comments. You don't want more mutable state across large scopes, but using intermediate names can help comprehension.

One of the main problems with violence inspired by morality is that many moral systems accept the use of force and thus violence as main course of action to improve the status of the world.

This makes moral systems that propagate principles of non violence, like Ahimsa, worth spreading.

I tend to agree. I've been using Swift off and on pretty much since its inception, and I like it well enough that I'd consider it for server-side stuff once the ecosystem's worth anything.

well, first you need to know what image regions feed to ANN, and that can involve some segmentation and pre-recognition, otherwise you're going to evaluate the net at all feasible subwindows — and that's a LOT of matrix math for you. Very big GPU can help, but they have latency in themselves, and FPGA at such performance levels are inordinately expensive.

> The commonality was that the primary motivations were moral.

I'm not so sure about this. Humans tend to act first and then construct a reason why they do it. This is used to rationalize the actions through some seemingly higher cause when the behaviour was done because of very mundane things.

Humans certainly always act in a way that they think is best for an extended version of themselves (good for me, good for my family, good for my clique, good for my country, good for humankind, good for the world). But I doubt that this judgement of what is best to do is so often moral. Most of the time it's actually just satisfying urges by our bodies.

How about a simpler solution? Designate certain roads as autonomous only to assure safe operation among other vehicles (for example highways do not allow pedestrians, bicycles, etc; we could require certain roads to be autonomous only as self-driving vehicles become more commonplace), and maps should be updated to identify all possible pedestrian crossings to drive pessimistically?
I have to disagree. OP might be right, but before we establish that conclusion, we have to try these things first:

Teach coding from young age. Are you really surprised that 18 year old CS undergraduates fail their intro to programming when they have to learn in 11-22weeks what probably took me say 6 years to learn between the age of 11 and 17? I have a CS degree, but I'm also self taught.

We have to acknowledge the vast breadth of the field and split the teaching to different paths. There is a reason we have chemistry and biology and physics, although it's all just physics. And we start splitting super early on. The same is needed for coding.

And I agree with OP that the perception of the field is selecting (self-selecting), and again we have to change that before we assume that people are born to be programmers.

Also, they didn't add up the numbers, it's over a half with a CS degree (gotta count masters).
I've long thought that UIKit (and supporting frameworks) need a simplified API. I also believe that the best "bang-for-buck" for developers is learning the platform APIs, not third party wrappers, since that's the most transferable skill. How do you balance those competing interests?

Fascinating article. Forgive me for being ignorant about this, but how often do they need to encode video?

I would think that it's only done when new titles are added to streaming, and once the video has been encoded into all the required formats they would be done with it. Sure, there is a lot of video content out there to be encoded but it isn't unlimited. Is serving the content and providing the recommendation engine to users at scale not a greater challenge than encoding the video?
If you have that information, you can factor that into your admissions criteria using feedback from previous students. For example, you could rank incoming students and tweak a racial parameter to equalize the 6-year graduation rate of the bottom decile in each race. Doing so will (by construction) improve the outcome of your 6-year graduation rate. Pick whatever is a good proxy for whatever your goals are.

That's more meritocratic than ignoring that information.

There is a different sense of meritocracy though, in which the goals themselves are unmeritocratic. For example, "educating lots of left-handed people" (to the exclusion of right-handers) is a rather unmeritocratic goal. The real argument being had is in this respect -- for one, whether educating should be done for students' benefit or for the sum of others' benefit. And also, in the subcategory of "for others' benefit," whether making maximally good scientists, historians, and the like, should be the goal, or whether and to what extent there's benefit in trying to infiltrate minority communities with a more education-valuing culture.
I've scanned the site and am a bit confused: I guess I was expecting something like Processing[1] or the like, but from the example it looks more like a framework with conveniences, dare I say similar to MPWDrawingContext[2][3] though with a slightly different domain.

However, except for a few examples (which look like convenience methods), I don't see anything that tells me what specifically this is for or how my code would benefit.

How about the car isn't designed with utilitarian ethics in mind and it instead automatically values anyone in it more than other people?

Okay, that's probably a very unpopular opinion, at least when expressed in that way. But to be perfectly honest, it's probably what a lot of people riding in said cars want to happen, and perhaps a bit closer to how cars work in real life when not driven by a computer.

Good luck trying to sell selfish AI to the public though...
don't take these self-important penny-pinchers you find on hn too seriously. their condescension stems from a fundamental insecurity of some sort that they're projecting onto others, it's hard to put a finger on but it's definitely there.

they don't know anyone's situation, they just know spending money on things you like is bad. it's like some kind of alternative religious orthodoxy. imagine if they had the same attitudes about the kind of books you read or the people you hang out with (aka how you spend your time, and time=money)

people should do whatever the hell they want to do with their own money, just like their own time.
Hey, I'm Ryan from RethinkDB. I wrote the OP blog post and I'm working on a follow-up that demonstrates how to use the Java driver in various alt-JVM languages.

You can take advantage of Clojure's Java interop to use the new official Java driver in Clojure, but it doesn't offer a very good user experience compared to clj-rethinkdb. It will work for a lot of simple cases, but it gets weird very quickly. When you define a function in Clojure, the underlying Java object is an IFn[0]. Unfortunately, you can't pass an IFn to native Java methods that expect to receive a Java 8 lambda (an anonymous class with a single method). You can work around this limitation by manually creating an object that conforms with the client driver's various ReqlFunction[1] interfaces, but it's not very pretty:

This ReQL expression in Java:

r.table("fellowship").map(x -> x.getField("name")).coerceTo("array").run(conn)

Becomes this in Clojure:

(-> (.table r "fellowship") (.map (reify com.rethinkdb.gen.ast.ReqlFunction1 (apply [this, x] (.getField x "name")))) (.coerceTo "array") (.run conn))

Note the use of reify and the ReqlFunction1 interface. You need to be careful to pick the interface that matches the arity of your anonymous function. For example, if you have four parameters, you use ReqlFunction4 instead of ReqlFunction1.

You could probably do some voodoo to abstract away some of the ugliness, but the way that clj-rethinkdb's r/fn macro works under the hood and translates into the wire protocol is frankly a lot more elegant than anything you could do with our official client driver and Clojure's Java interop IMO. That said, I'm not particularly well-versed in either Java or Clojure, so there may be something I'm overlooking. I hope this explanation is helpful to somebody. :-)

TL;DR: use clj-rethinkdb if you want to write sane-looking ReQL in Clojure.

Scott Aaronson is fucking awesome. Whenever there's a new paper claiming breakthroughs about quantum computing or P=NP, I go to his blog and wait for him to clearly explain it.

He is the very rare case of a top notch scientist with a gift for explaining things well.
Thanks so much - really glad to hear you made some music on our platform. I'd love to see the game you use it in when it's finished!
I'd be curious to know why you left!
He can sign with the private key of one of his early mined blocks
That is the central open question. That's what Scott means when he talks about asymptotics, and the conclusion of the Google paper is that we have probable evidence that with enough qubits and a big enough problem it will be faster for a very specific problem compared to a non-optimal classical algorithm (we have ones that are for sure better).

This probably sounds like a somewhat useless result (quantum computer beats B-team classical algorithm), but it is in fact interesting because D-Wave's computers are designed to perform quantum annealing and they are comparing it to simulated annealing (the somewhat analogous classical algorithm). However they only found evidence of a constant (i.e. one that 4000 qubits wouldn't help with) speed up (though a large one) compared to a somewhat better algorithm (Quantum Monte Carlo, which is ironically not a quantum algorithm), and they still can't beat an even better classical algorithm (Selby's) at all, even in a way that won't scale.

Scott's central thesis is that although it is possible there could be a turning point past 2000 qubits where the D-Wave will beat our best classical alternative, none of the data collected so far suggests that. So it's possible that a 4000 qubit D-Wave machine will exhibit this trend, but there is no evidence of it (yet) from examining a 2000 qubit machine. Scott's central gripe with D-Wave's approach is that they don't have any even pie-in-the-sky theoretical reason to expect this to happen, and scaling up quantum computers without breaking the entire process is much harder than for classical computers so making them even bigger doesn't seem like a solution. My personal frustration with D-Wave's marketing is that the fact that their computers are super specialized often gets lost; these computers fail the equivalent quantum notion of a complete set of digital logic gates.
You don't what?
When will they start selling music in FLAC?
Yep, checkout atheerair.com
Exactly. There can be very many different flavourings and some are probably harmful, just like some food is harmful, particularly if used in excessive amounts. Or listening to music at loud levels is bad for your hearing, and still, earphones are not banned (and we don't even have mandatory fuses in earphones to limit the power emitted to ears).
> Also take a look at the Church-Turing thesis

The Church-Turing thesis is an (unprovable) statement of faith, not a mathematical theorem.

Effectively, it states that "all algorithms can be computed on a Turing machine, and vice-versa".

Note that this thesis is not as radical as it first sounds; I'm assuming that if we ever do find a way of computing functions that cannot be computed on a Turing machine, then we'll just call it something else, not an 'algorithm'. This would make the Church-Turing thesis just a tautological circular definition.
> but not able to isolate uim from innocents

I often wonder what's the internal thinking of professional- and military-trained people. It could be closer to "I don't know whether they are guilty, but this is just my job" or "Precision destruction is a notch better than bombing a whole city like UK did in 1944 to win the war". Or "There isn't a right or wrong, but I'm on the US side, which has determined that this is "our" truth".
But, but, but - what if I use a D-Wave machine to solve it? ;-)

What's missing would be a Async Interface. Especially with Java8 and CompletableFuture, which will be interoping in Scala 2.12
I believe the word is "context."
That's a decent solution for some roads, though it still doesn't solve the issue of how these cars will work in towns and other highly populated areas, where pedestrians and cyclists are everywhere and they can't reasonably be expected to only be on the pavement or only cross by pedestrian crossings.

It also doesn't really work outside the US, since a lot of places are quite fine with 'jaywalking'. For example, in the UK, you can cross the road just about anywhere. These autonomous vehicles will have to programmed with this in mind.
I agree. It's not that I prefer to validate those comments.

No, it's more about understanding. Personally, I would rather see the context and know something about the conflict than see [flagged] and see worthy rebuttals out of context.
So how do you feel about this Satoshi message? Is there any chance it's real? Or just noise?

No idea what to make of the situation anymore, or what to believe. I guess there's no way to know?
That's a really interesting way of using this - to make music that no one else will hear. We might explore that some more!
Definitely share the feeling.

I've never been a huge fan of their products, apart from HipChat (a bit too "enterprisey" for me). My initial experience with Jira had been pretty bad and I just had labeled Atlassian as boring/enterprise/old school.

That was until I read a piece about the two founders (I believe in Forbes [1]) and started digging. I'm still not interested in their services but I find their story pretty interesting; they definitely look like a pretty good company, built by two hardworking Aussies who have fairly conservative and rational ideas about business. It's pretty refreshing in a world of VC hungry ventures.
