>The way you're describing the theory sure seems like the Ensemble Interpretation to me, but to be honest, I have never heard of the "Statistical Aggregate Interpretation".

yes, my mistype, it is basically Ensemble Interpretation.

> However, the probability density you gave for the frogs in the classical case, cos^2(pi*X/A), is incorrect.

it isn't resulting probability distribution on the wall. It is probability distribution of the frog legs touching the ground on a radial line from door to the wall, i.e. peaks at 0, A, 2A, 3A,.... It is about the same as position operator for electron would produce on a radial line from slit to the screen.
Also note that the frog doesn't interact with the wall if the frog is "airborne" (i.e. one can imagine that it just goes through the wall without leaving a wet spot or even better - the wall is too low, say 0.1m , so airborne, mid-flight, frogs would fly over it).

If you look at this image

http://micro.magnet.fsu.edu/primer/java/interference/doubles...

the red concentric lines is where a frog most probably touches the ground and the greenish-yellow - where a frog is most probably mid-jump airborne (flying at the height enough to fly over the wall). Where 2 yellow-greenish lines intersect right near the wall - it is the place with minimal probability of a frog landing near the wall, ie. dry place. While intersection of 2 reds - correspondingly a very wet place.

>The fact that electrons in Hitachi's experiment display a "many-humped" distribution is good evidence that the electrons are not following the same rules as the frogs, and hence that the electrons are behaving non-classically.

this non-classical behavior is the quantization of position, ie. position probability density looks like concentric waves starting at a slit. I.e. cut along the radial line, the profile of that density is a correctly scaled cos(x), with x - distance from the slit. The superposition isn't necessary for the observed effect.

>> in Hitachi experiment it is shown explicitly clear that quantum interference is emerging only for multiple particles.

>This is the exact opposite of what the Hitachi experiment shows. The experiment is interesting and surprising precisely because particles are sent one at a time but still show an interference pattern. The experiment shows a single particle interfering with itself.

i'm trying to understand where do you see the interference of a particle with itself. Lets say the experiment was run only until there is only 1 (i.e. 2 sec into the clip), or say 3 particles hit the screen (4 seconds into the clip). What would be an indication of the interference in such a case?
Worth noting that Lewitt had draughters construct his work from instructions, as the students have done in this task.

I've stood in a gallery and followed a different Sol Lewitt location drawing before and it had a similar error - an instruction missing.

I wonder, then, if these are deliberate omissions on the part of Lewitt?
anyone can make a license that is both open source and providing warranty btw.

open source licenses generally don't provide warranty because they don't have to and devs, providing free stuff, certainly do not want to bother with warranties.
Companies could.

you can mark sub-scopes with their own itemscope property, so you could have this:

<article itemscope itemtype="/article">
<h1 itemprop="title">My Title</h1>

<div class="related-thing" itemscope itemtype="/author" itemprop="author">
<h1>
<span itemprop="firstName">John</span>
<span itemprop="lastName">Smith</span>
</h1>
</div>

<aside class="incidental-unrelated-thing" itemscope itemtype="/sausage">
<span itemprop="type">Cumberland</span>
<span itemprop="ingredients">Mystery Meat</span>
</aside>
</article>

in the example above, we define an article that has a related author property, that author property is its own scope so has firstName and lastName properties of its own. We also define an unrelated itemscope (unrelated because it has no itemprop) that happens to be nested in the same element, so this would parse to:

[
{
"type": "/article",
"properties": {
"title": ["My Title"],
"author": [{
"type": "/author",
"properties": {
"firstName": ["John"],
"lastName": ["Smith"]

}
}]

}
},
{
"type": "/sausage",
"properties": {
"type": ["Cumberland"],
"ingredients": ["Mystery Meat"]
}
}

With all respect, you're better off using a supportive regex environment that accepts your regex entries and quickly shows their effect on some example text you provide -- a builder/tester like this (just an example, there are many similar ones):

http://www.arachnoid.com/regex_lab/

Philosophically, there are two approaches to making regexes an effective tool -- expand regex syntax until it's so verbose that there's no possibility for confusion -- ironically a somewhat confusing tactic as this topic's comments demonstrate -- or learn native regex in an interactive way that shows its effect on example text, until you develop an instinct for it. I prefer the latter.

It's like learning music by keyboard -- shall we paint each keyboard key a different color and recode sheet music to agree, or shall we use a teaching method that makes the keyboard gradually seem more natural?

Second, it would be great to have more clips of each language, without having the same person speaking twice. The educational element of the game gets lost when you start overtraining on the same clip.

Exactly! I got Swedish vs. some Asian language once, correctly guessed swedish and then the next round was the same audio clip and some other languages. The game had told me that it was swedish already, so it was easy.
Well, distinguishing standard Serbian, Bosnian and Croatian is impossible even for native speakers, as it is in fact one language.
The division being merely a political one.
One can only distinguish accent subtletlies in certain words.

It would improve fairness of the game and avoid a lot of confusion not to allow these languages appear in the answers together.
Mobile phones, built like a brick, running for days

The sad thing is that someone at Nokia seems to have just remembered those days and they've just announced the Nokia 515. A solidly designed aluminium and gorilla glass 'dumb phone' with a 30+ day standby time.
Can I add my own conspiracy theory and put forward that MS wanted to buy Nokia years ago when the world was going mobile but couldn't. Then one by one, MS VPs mysteriously left their posts to go work with Nokia. Fast forward to today, MS finally buys the firm they wanted to in the beginning.
In the article, you wrote you gave your MacBook Air to your girlfriend. I guess she doesn’t use it often and you have made separate user accounts?

As for the part about you wanting a gaming PC anyways, I had somehow missed that. (I have to admit I zone out whenever video games are mentioned.)

If you look at Mega API and SDK, design wise it is very clean. You can build your own custom application by importing those libraries which are not prone to this kind of attacks.

Google/Android really can't win now that this "fragmentation" frame has stuck.

Google's been updating core parts of the system like this from day one. The Android Market/Play Store, Maps, Youtube and many other things have received massive updates and been pushed out to millions of people. However, the dominant storyline at the time was that "Android devices don't get upgrades, because fragmentation".

Then suddenly, for no obvious reason, the tech bloggers all noticed at once that this was happening (possibly because they had started actually using Android?) and it was portrayed as sudden U-turn by Google. A weapon in their "war" against Samsung (don't get me started on that one).
Well, the new DRM framework definitely isn't open, and essentially all the things you list are stuff that's too low-level to be implemented as part of Google Play Services. Basically, if they could put it in the closed source Google Play Services, they have - including relatively core functionality like improvements to the location APIs and push notifications.

Email addresses are specified by standard with a context-free grammar. While it may be possible to express certain CF grammars as regular grammars, you rapidly run into issues (such as optional bounding delimiter matching, or escaped delimiters) which are trivial to express with a stack, and frickin' hard to express without one. (This is, incidentally, the heart of the "don't try to parse XML with regexp" sentiment, because XML is (at least) a context-free grammar that cannot be properly expressed by a regular grammar)

If you are having severe problems with a regex, the issue might be that you need to use an actual parser rather than a simple pattern matcher.

Ask HN: What do you call the box with the CPU in when talking to non techs
I was chatting with some low-tech friends, people who use their computers for day to day desktop tasks, about terminology for the parts of a home computer and we realised that for a non-laptop, non-all-in-one there doesn't seem to be a consensus term for 'the box with all the bits in'. Think classic beige box desktop tower, that bit.

We decided that 'hard drive' would be the best bet for general understanding amongst ourselves, but this niggles my pedantic geekery. What term do you use when you're trying to point someone to 'the bit that actually has the computer in'?
> Building a hackintosh is all about selective hardware

Exactly. I bought hardware based on one of these lists and had no issues with my Hackintosh since building it (almost 1 year ago). Also, the build took about the same time as any computer would. I think I had to install one driver post-install, but that's all the 'hassle' I've experienced.

And researching what hardware works well with OS X doesn't take more than 5 minutes since people compile lists and/or entire build guides for every version of the OS.
You have the same problem with, for example, iOS devices though - there are games out there that don't run on older devices even though they're all nominally running the same OS because the older devices are too slow.
maybe it sounds irrelevant, but always i wonder that, why Nokia pays less attention to Linux, a Finnish company and an OS born in Finland? Only a few Nokia devices run some kind of Linux and i think they are not so bad (my favorite is N9, btw).
In Silver Lake, some have reservations about vacation rental website
I guess I must be in the minority. I've had 3 Hackintosh machines in the past, all with different hardware. They have all worked almost perfectly.

Each one did require some post-install setting up. For example, dual monitors, sound card issues, graphics etc. But the set up never took longer than a few hours, and I get a machine that is 1/4 the price of a retail Mac.

I also think I can count the number of the times they've crashed on one hand.
1400 but that's only because I'm interested in languages. I speak English, Swedish, German, Romanian, can read the other roman languages ( French/Italian/Portuguese/Spanish) can read and write Farsi. I have no problem differentiating between Cantonese, Japanese, Mandarin and Korean.

The quiz is most difficult when presenting me with choices between slavic combinations (Ukranian/Polish/Russian) and far east weirdness: Tamil / Burmese / Malay.
I would prefer to say that the Board of nokia is gone full retard hiring him as ceo.
OR they knew since the start that M$ was gonna buying them.
I sell a Mac about every year. It takes me under 5 hours of work. That includes formatting the drive and reinstalling OS X, placing the ad, negotiating with buyers, and having them visit to inspect it and seal the deal.

It isn’t skilled work and it’s not taking time away from my actual work. It’s hard to put a price sticker on, just like I don’t calculate how much money I waste by going to a movie.

There is another reason why I didn’t mention the time it takes for resale. From reading the article I got the impression that OP didn’t count the time it took to research the various components of his Hackintosh, the time it took to look them up and order them, and dealing with the delivery. I think those activities easily take longer than reselling a recent Mac.
I've not found a good answer to this. Non-techies have definitely called it a 'hard drive' to me before, but this is wrong and can be genuinely confusing (especially if they have an actual external hard drive on the desk too).

Happily, my family all have iMacs or laptops these days, so the issue has gone away. :)
They could, but I seem to recall issuing TRIM commands can brick the onboard eMMC Flash chip on some Samsung devices.
I wouldn't limit it to the really big acquisitions. If the market says jump, the desperate company does it ASAP and invariably bumps their head on a sharp pointy object.
Um, no. See under Linux Desktop. Big fail, over all these years, even if it's more capable of Windows. It's more capable of Mac, too, and guess what most nerdy types with enough money buys?

Users don't give a damn about Open Source. They don't even know what Open Source is (just ask some average teen girl with Android phone what she thinks about Android openness). What they want is an acceptable shiny device that does things. Samsung provides that. Apple provides that.
The story of microsleep
The Humans with Super-Human Vision
Most of the phones running 2.3 aren't shipping with Google Play (is Play even compatible?), so there isn't the integrated app marketplace that defines the modern smartphone experience.

These are drastically underpowered devices. Even if an app can run on 2.2, it doesn't mean it'll run well (or at all) on sub-$100 hardware.
I don't think regular employes get to keep their laptops :)
A closed source app that can update itself without notifying the user, and has full permissions? How is this any different from the 'loss of control' to American institutes, like the Windows 8.1 / TPM 2.0 warning from the German government. Isn't this exactly the same thing?
I'll call it the 'tower' usually. If it's an oldschool non-tower case, you'd probably be stuck using multiple words.
"Open source" has always been about marketing and convenience. If you're looking for "freedom", you should join the "free software" movement instead, which is a distinct one.

Back in the days, people argued that free software will not survive if they keep being idealistic. Instead, people argued that free software should market more, and compromise more with proprietary software. Well, here is the result.
Ask HN: I do not enjoy my job, what to do?
Hi,

I am 25 years old, and completed a computer science degree 3 years ago.

For the past three years I have been in a permanent full-time position as a computer programmer. However I do not enjoy this job. I have very limited time to explore new interests, and in addition due to where I live, it takes me 2 hours of daily travel to get to the workplace.

What should I do? I am unsure if I should quit as everyone I have spoken to mentions that I should be grateful that at least I have a job in this economic climate, and that all jobs have some disadvantages.

Also I do not know what I would be able to contribute of economic value if I was to become unemployed, or if I could even find another job outside of ICT. To be honest I would rather be outside, meeting people and creating things rather than sitting in an office all day 5 days a week. I feel that I currently only have my programming skills and have no idea how to safely move to something else.

Thanks

As a developer in Norway I am very much delighted to see Stripe roll out in Europe and hope to see more Stripe links here on Hacker News!
Elop only joined Nokia towards the end of 2010. Nokia was well and truly on their downward slide by then.
Definitely welcome. Operating from Belfast, the intersection of a kind of Ireland/Britain venn diagram, options for accepting payments have been seriously limited for us. We've been using Fastspring so far and it has been great for abstracting away problems like when to charge VAT, PCI compliance, multi-currency charges etc. It got us up and running. But we're paying 9% on credit card transactions and directing people away from our app to make payments and that's not good.

Luckily we got on the Stripe beta early. They've addressed multi-currency payments well. Our use case demands quite a bit of (re)development so it's not in yet. We're literally (figuratively :) chomping at the bit to get it installed though.

Clearly you have not dealt with other payment gateways. Regardless, news about payment gateways is interesting for developers because we have to implement them. And some of us are entrepreneurs and we have to choose a payment gateway to get money from our customers.
