In interpretation of dual slit experiment people do the main mistake of mixing up the 2 waves - one is wave like quantization of position and another is de Broglie wave-equivalent of the particle. The mix up is caused by photon where both have the same wavelength. They are different in the case of all other particles. Hitachi experiment shows its the best - it clearly shows interference of the positional waves of different particles, not the de Brogile wave (ie. not the particles themselves). It thus also lends very credible support to statistical ensemble interpretation (which, as far as i know, Einstein favored)

People frequently bring up single-particle self-interference as explanation for Hitachi too. Well, in case of photon the self-interference pattern looks the same as positional interference because of the same wavelength. In case of electron and especially neutron the self-interference pattern would be much more dense than observed one because of the much higher de Brogile frequency than the frequency of the positional quantization.

The wave-like quantization of position is the Pivot Wave. The really important thing here is to understand that Pivot Wave isn't a real wave/object. It is just a description of possible positions of the particle at specific times. Like a trajectory of a bullet isn't a real thing, it is just description of possible positions of the bullet at specific times. It is just in QM the trajectories are wave-like quantized and probabilistically spread - that the non-smooth at small scales structure of our Universe shows its "ugly" face :)

Again, taking the quantized wave-like trajectory description of a particle for a real thing, the particle itself, is the main misinterpretation that has been going for years, especially in Copenghagen interpretation.
That's fair as far as it goes. But you can mix NFP with other birth control methods to combine the advantages. Sex without condoms is valued by lots of people, so it's useful to know that even if you use condoms the rest of the time. On top of that, NFP can also help if you are trying to get pregnant.
Can you give some examples? I'm failing to see how this was a step backwards.
As rants go this one is good because it identifies some language features and misfeatures that are important, such as type system complexity. But Will Yager's recent article was much better: partly because it was not a rant, and partly because it succinctly covered all the bases.

We've reached a point in time where there is a wider consensus regarding the importance of stateless programming, option types, code re-use, and the productive people are not complaining anymore and instead are doing something about it. There are many new or recent PL projects ongoing, where people are designing new languages.

In the mean time, for those people who roll their eyes at missing GUIs or support for email addresses -- it seems to me they've identified an opportunity.

There is a rich set of choices out there and the hard thing (for people who aren't designing their own language) is shopping. Those people who can make effective decisions and exercise good judgement are going to have an advantage, whereas other people who expect others to deliver popular platforms into their hands for free, will remain below average.
Well I think in this case the language does fit the task at hand, since the language choice is one of communication (communicating concepts), it's probably a wise choice to go with a ubiquitous one to achieve the goal of delivering a message to the widest possible audience with the least friction possible.

I don't know if English is better or worse than Lithuanian, but none of that probably factored into your decision to speak English here rather than your mother tongue. Like many of the other non-English speakers I see on HN, I don't assume you are saying English is a superior language, rather I assume it is that you see as English is the lingua-fanca of the world currently, you want to lower barriers to understanding your concepts and communicate to the widest audience possible. If that is why they chose JavaScript, then to me, that's a rational choice.
This is creepy.

It's like you counter low GPD growth by
1>high government spending/invesmtent in the economy.
2>low interest rates.

But both of these are already as high/low as it can get and still no response from GDP.

Weird.
> The fuel price have been stagnant for the past 60 years. If you use real money, i.e. gold or silver.

Since most people would disagree that gold and silver are real money, the burden of proof is on your side. I think an equally compelling explanation for your observations can be built from the premise that gold in particular has been inflating an speculative bubble during the same time frame of 50+ years (or more precisely, that since about the 2nd half of 20 century gold price had been recovering from a previous drop in historic prices, and that a bubble has formed around that pattern and just began to inflate about ~10 years ago).

If on the other hand you consider the fact that petrol is a finite resource, and that the challenges to build a flying device powered by either nuclear energy, solar, wind or hydro, it is very likely that tourist class aviation will be in permanent decay from now on.

I think the capacity to fly is extremely valuable, so it will be preserved by nation states for as long as possible, mainly for military purposes, but also for the rapid transportation of diplomats and other high ranking officials. And if the technical capacity of flying is preserved in any way, the upper layers of civil society will find a way to buy their ways in as well (bringing back the original meaning of the term "jet set" as a side effect). But, mark my words... the days of regular, scheduled flights for the hoi polloi are numbered.
Q1 2014 GDP growth was -2.9%. There's no minus sign in front of 2.9% in item #1 in the article (I'm using Chrome).
I disagree with his premise. I don't know which people he interacts with that consider Bash to be some sort of "optimum of productivity".

I finally appreciated Perl after spending a couple hours trying to write a non-trivial Bash script.
I think it's really awesome that several emoji redirect on Wikipedia to pages about what they represent.

Has our obsession with technology created this expectation of hiring "fire and forget" agencies that work like perfect little robots, do all the killing, and then leave no upsetting damage in their wake? I'm unsure about that myself, but when I see humans attempt to hire (on the one side) or act like (on the other side) humans that will supposedly behave just like computer software and only do what they are told, I really wonder what sort of things have established that expectation.
This is not as big a problem as you believe it to be. The independent contractor test is a balancing act. It is not an absolute barrier to you personally working on behalf of a particular client.

Kalzumeus Software maintains a fact sheet, because that sounds better with "Word document". It's one page and starts with the words "Patrick McKenzie is, under relevant IRS regulations, an independent contractor and not an employee of your company." It then has a bunch of bullet points where I recite the facts which are most supportive of that conclusion.

This has resolved 95% of interactions I've ever had about this question. (The last 5% was at a particular BigCo where they wanted me to fill out a BigCo-approved questionnaire, but they reached the same conclusion.)

I second Thomas' comment that this is largely a sales question rather than a legal question. At a lot of places, "I want an agency in front of you" just means "I want someone to yell at if you turn out to be a bozo." An agency is one way to decrease the downside risk of you being a bozo. Or you could just have a bunch of strong signals which say "Almost certainly not a bozo." If a potential client said "Patrick, we want to work with you, but we'd rather do it through an agency." I'd say "Can I ask what is motivating your desire to do it through an agency? I might have a solution for you."
That's like saying it's discrimination that a tall person has to buy more food to survive.
I wouldn't be surprised if there were. There are plenty of up-and-coming cities with relatively low car ownership (and lots of growth) today. An autonomous-zip-car-ish offering wouldn't have to displace existing motorists to become dominant in such cities. It would just have to outgrow individual-ownership, which would seem more likely than not. Particularly as it subsumes the entire cab and rental industry.

It's just a question of "at what point do the consumer-facing products actually exist?" over that 25-year scale.
Node.js streams are largely unicast, instead RxJS and related libraries can be multicast. RxJS, on the other hand has been fairly stable for quite some time now and the APIs largely haven't changed from when we first released in 2010.
Let's ignore the fact that Barclays manipulated the data underlying the chart in Figure 1. Think about what the chart is intended to convey.

One-second alpha, on the vertical axis, measures an "excess return" certain market participants earned over a 1-second trading interval. It represents skill in trade execution. What Barclays is saying, by pointing giddily at the bubbles in the lower-left quadrant, is that it has collected a fruitful variety of institutions particularly rotten at competently executing their trades. The customer being pitched is being told that it, being smarter than all those clowns, can now take advantage of their naïveté.

If I were an existing customer, I'd be insulted to be so portrayed. Or maybe not. Maybe I'd assume I was the lone smart bugger in the top-right. I guess that's what this chart counts on to generate, not lose, business.
I wanted to make a personal blogging platform for myself to vent to. I often vent on tumblr, but it annoys my friends. So why not vent to /dev/null? Same effect, but /dev/null doesn't care about my feelings. It is always there to comfort me. It's never going to give me up, never going to let me down, never going to run around and desert me.

(Apologies for the rickroll, but that was a serious idea of mine.)

The defense budget has gotten smaller as a total percentage of the economy since WWII, but the economy was smaller and the entire country was mobilized.

We currently spend over a trillion dollars a year on defense and intelligence. "Entitlements" are not the problem.I love how they are entitlements even though you pay for them...in fact, let's start calling it the social safety net instead.

The main problem is that the wealthy, corporations and individuals, don't pay enough. Cut defense by half and stop letting the wealthy walk all over us and all of a sudden you don't have a crisis.
This is not true at all. It is only recently and only in the SF hacker bubble that FRP has been co-opted to mean anything that is functional, reactive, and programmed.

Outside, FRP still means FRP, and using the term will automatically put your work in a certain specific bucket that you might not want to be in.
Yes. I was once presented an option of paying either the Gas and Electric bill for our half of the duplex house that I was living in, or paying the rent and a share of the utilities (since nobody else would do it.) We renewed 18 month leases two or three times, with either four out of six or four out of eight tenants signing.

None of this ever appeared on any credit report. I don't think I actually believed it would improve my credit score, but when the rental company came and threatened to evict every tenant for the third time (presumably because it was a dilapidated, drafty old flophouse and nobody wanted to sign a lease renewal), everyone took the opportunity to move out and I was stuck with the entire bill for half a house, for the extra two months I needed. (I managed to split it with someone and get the hell out.)

In the cold winter months, gas heat cost more than the rent for the entire half of a house. In the summer, I could get away with paying sometimes $50 or even sometimes $0 for a month, due to past estimated bills that were over actual usage. That was nice, but it really sucks getting stuck with all the bills when everybody splits because someone convinced you it would be a good idea to put your name on as many things as possible.
That reminded me of the waterboarding demo on the news years back, where the torturers played popular music on the stereo while they administered the torture. Not sure if that's a real thing, but it made an uncomfortable news segment even more uncomfortable.
I'm impressed by the probability distribution graph in the video. I would never expect the random motion to form a wave!
On HN, users cannot downvote replies to their own comments. Or at least I can't.

That said, I don't know from political incorrectness, Irene, but your reply did introduce a racial angle to the thread that confused me.
Well, those markets are not fully informative so they are "markets" in some sense not in the "common meaning of the word." Hence the "opaque" adjective. I would not like all markets to be of this kind.

Immediate mode UI is more continuous (refresh every 15 ms) and not stream-based, which is actually quite different from Elm and is more like React.
This is a shrewd observation.
He just suggested a basic income for everybody.

I just wanted to point this out in case people missed it when skimming.
I thought that they were called entitlements precisely because we pay for them.
I disagree that the name for something like this is a trivial decision. Especially when considering the name for a framework which will need to be discoverable on Google to gain popularity. And even more especially when you choose to name the framework for working with a technological concept in one specific programming language the same thing (albeit different casing) as that technological concept itself.

How is that not a really important decision that should be considered practically? If I want to query Google for REST vs. Rest, or even converse with people about it, you don't think that will quickly become (needlessly) confusing assuming the framework becomes popular? And if you aren't expecting the framework to become popular, does that make it OK to choose such a lazy name?

But, hey, at least you got to namedrop the term "bikeshedding" along with your highly specious argument.
How is this different from feedly other than that it has no android or browser support?

I was expecting a media wall like sc2daily, but with tech information.

edit: it has browser support, I didn't see the button earlier.
How could you have a linked list with a loop in contiguous memory? Or in an array?
Thanks for the feedback. Our app lets you follow lots of well know writers / bloggers from various disciplines. It's like curated RSS without the hassle. Tech is one of our main focuses and I wanted to highlight that aspect for the HN audience and list a few of the dozen tech authors we have currently but you're right that it is not completely tech focused.

NTP exists so we don't have to own this hardware. You can easily expect to be within milliseconds of UTC if this is working properly and you're syncing with stratum 1 servers.

And better yet, the hardware to do this yourself isn't really "fancy" anymore:

Could you be more substantive with your analogy. Ferrari is producing cars in a category because they have buyers/racers who want/need it. NASA wouldn't be interested in making luxury spacecraft just because they can.

I'm more interested in your argument about what's the "value per dollar" that the two missions are achieving (rather than equating them with GM & Ferrari). This PSLV sent by ISRO was used to piggyback satellites from Canada, Germany, France & Singapore.
I guess that's what attracted people to Python some ten years ago, as opposed to Perl. One can be sure that CPAN has a Perl library fit for your needs, but having such features in the standard library makes a big difference for a newcomer.

The same could be said in the devops context with Ansible vs Chef/Puppet. Ansible joined the game pretty late, but it's attracting a lot of users because of its "batteries included" philosophy. But this battle is still ongoing and only history will tell us the winner.
I feel like the author of this piece doesn't really have personal knowledge about what he is talking about.

I use Go and I use Erlang. I've never used Akka.

Go is not in the same class as Erlang when it comes to Cloud Computing. In Erlang the state and behavior of your entire datacenter can be contained in Erlang itself. Erlang will take care of bringing up new processes when your jobs break. Erlang will handle messaging between processes executing on different machines.

Go doesn't do any of that out of the box. There are some interesting projects like Go Circuit, which sort of kinda want to emulate Erlang's OTP and bring your datacenter behavior into Go, but Go Circuit isn't being run in production by anyone I have heard of. Maybe its ready to go, but it looks more like a research project to me.

As such, Go has nothing to do with managing a cluster other than that it gives you some nice single node concurrency features. You will need to build or import everything else you need.

I can't think of anything else out there which is quite like Erlang/OTP. Maybe Julia has some tools that are similar but I don't know too much about it.

Edit: For those Go programmers that are interested in what I'm talking about, check out this concise explanation from the Erlang docs:
http://www.erlang.org/doc/getting_started/conc_prog.html

Erlang isn't as user friendly as Go, but it has a lot of stuff that can save you serious headaches if you think you will need to scale. Premature optimization is a waste of time ... blah blah etc., so maybe you don't need it for your project. Also Go on App Engine allegedly scales pretty well with very little programmer effort.
They are called entitlements to make people think that some undeserving class is getting over...they think they are "entitled"...is the way that is put. It was done on purpose by conservatives. Its a dog whistle.
Funny, on my FB feed just last week a woman posted an X-ray or some such image with the caption "perforated uterus due to IUD migration" and another woman commented on her photo that it had happened to her too. I don't know how rare it is but that possibility alone would be enough to make me turn and run the other way. At least condoms generally won't perforate your internal organs.
I've frequently heard the idea bounced around that self driving cars will eliminate the need for ownership. I'm glad you mentioned taxis, because it brings up something that has bugged me about this idea for a while. I live in a metro area of 200,000. This metro area has exactly zero taxis. (We do have a free ride services that is funded by the local city for getting the elderly and disabled around, which probably has six cars.) The three reasons are size density and wealth. As density goes down, mileage to get from point A to point B goes up, which means costs go up. It also means that cars are potentially occupied for longer periods, so you would likely need more cars to service the same population in denser areas. So ultimately taxis are not economically feasible here. So because you don't have to hire drivers, those costs go down and potentially lower the barrier to entry, but you have potentially more expensive vehicles, and higher maintenance costs that may somewhat offset the savings. So you could charge more for the service here, but being a poor city, would anyone here pay the extra costs? Enough to sustain the business model? Or will we have to suffer with significantly worse service--wait an hour to get picked up. I'm sure the business model would work in SF, NYC, Chicago, but here it will have to come down a lot in cost. Also (to the parent poster,) I just see the possibility that a migration like this could take place within 25 years just ludicrous.
Can you please explain how taxation plays into this? Are you implying that decreased investment in roads coupled with increased investment in public transit would increase taxation? What's your argument?
" Personally, I think that current levels of entitlement spending are ok (thought maybe the spending should be distributed differently), and we should probably do more. But I think we need to plan for it. In addition to thinking about new sorts of jobs to replace lost jobs that aren’t coming back, we should probably think about things like a basic income."
Seconded. The AJAX UI sucks the most of all. Try loading up 100 pages of threads on one screen, selecting 19,850 spam threads to delete, and finding out an hour and a half later that your request is too large and all your work is lost.
It looks like it's mostly medical costs. Social Security and other such things haven't increased much.
I surely prefer a language that comes with HTML/JSON parsing in the standard library, as opposed as trying to find which library is better implemented, hoping it will keep being maintained.
It seems to be some mention of the urban legend, then pedantry. In particular, the sentencing parameters of Swartz's case are nuanced. The statutory maximum number of years is different than what a defendant was likely to have been sentenced to by a court which is different than what the prosecutors announced in their public statements which is different than than what a plea bargain might have entailed for a person willing to admit to a felony. So somebody mentions one number and somebody else comes in saying that number is inappropriate and we should really look at this different number and a third person picks a third number and we all start pedantically defending the respective positions using all manner of minor details that make no progress toward a solution.

It all seems like talking past each other. Is there anyone who sincerely believes that sentencing and plea bargaining are not broken? Is there any legitimate reason why statutory maximum sentences should be an order of magnitude or more longer than typical actual sentences, rather than more clearly delineating what conduct constitutes a serious felony as distinct from a misdemeanor? What are the practical ways of reducing the coerciveness of plea bargaining so that there isn't so much pressure for a defendant not to demand his day in court, or to make it so that doing so does not induce bankruptcy for ordinary people? These questions are more interesting than discussing whether a particular prosecutor said a particular thing on a particular day for the seventeenth time.
Yep. They had questionnaire about what things to improve with sites and which features are used and which aren't. So hopefully they're upgrading it.
You allocate an array of objects that contain pointers, then link them together. It does not have all of the typical benefits of a linked list (in particular, there's a hard max size and may require a fixed size, depending on just what you're doing to it here) but it does allow O(1) reordering elements for a list-order traversal, while also allowing a linear traversal through memory.
