Think of this from the viewpoint of changing demographic:
People get older and need to taken care of, which is shockingly expensive.

There are several attempts, with prototyped like housing/neighborhood scenarios, where the younger generations (students) live together with the elderly.
Older people might live in the ground-level apartments, while the young students wouldn't worry about walking up 2-3 flights of stairs. They could do some shopping, basic housekeeping, watch them take the right medication in the morning.
In return the elderly could return the favor by exchanging non-monetary things, like home-made food. Or they could just pay for the students to lower their rent.

All those solutions are great, but they require serious building of infrastructure, which can't be done immediately.

So services like the one described above seem to be an intermediate solution.
The problem is that all those "micro-tasks" (take the cleaning the litterbox example) are too easy/short to be paid a sufficient amount of money to be done. It's an entirely different league if you pay a gardener to come to your house twice a week for 3-4 hours.
And even gardeners/poolboys etc. have issues if they have to drive from client to client for 30min. or more.

It would be great if there would be a platform that allows people living geographically close together share a qualified person doing specific services.
Take someone walking their dogs every morning as an example. The cost can be shared amongst 6-10 dog owners. While the time spent for walking 6-10 dogs might only double (you need time to collect and return them) instead of increasing 6-10 fold.

So the service should bundle and curate requests from a neighborhood or house.
If a couple requests are similar, like "I would love someone to clean my windows every X weeks." They get bundled into a service package for which local contractors provide a quote.
And other people living in the neighborhood can then pledge for the service. With every new customer joining the average price is lowered for everyone.

Kind of like a curated form of a cross between taskrabbit and kickstarter.
Correlation does imply causation. It does not guarantee causation.
The terminology appears to be somewhat mixed up. xplusone<int> is not a specializaton, just an instantiation of the template.

Specialization is when you tell the compiler to use a separate implementation of a template when some or all of the template arguments match something. Template specialization is used in the type traits section of the post.
Show HN: KinoHunt – a movie price tracking iOS app
Hi,
We are a team of developers passionate about movies trying to solve a problem:
* Watches a lot of movies at home, but find fewer and fewer good new movies on Netflix
* Redbox is the most economic alternative, but still not as convenient as downloading the movie from iTunes and Amazon. However, iTunes and Amazon are relatively more expensive.
* iTunes and Amazon movie frequently change prices, but there's no easy way to track them

Hence we created KinoHunt (www.kinohunt.com), an iOS app (https://itunes.apple.com/us/app/kinohunt-price-tracker-to/id837941930?ls=1&mt=8)

With KinoHunt, you can "hunt" for movies you want to watch and create a smart watchlist. We track the prices of these movies in your watchlist and inform you whenever the prices drop on iTunes or Amazon.

You can also set a price filter and check out what good movies are available given your budget.

Would love to see if this is something others would use, also any feedback on the UI is appreciated.

Thanks for your time!
> If you're going to put in the effort to generate unit tests then why not go a bit further and formally verify the correct functionality?

At the moment this "a bit further" is a bit like saying if you don't like the price of milk at your corner store, why don't you go to a farm to get a quart? Sure, you might be able to do that, but it's not exactly a comparable effort.
So finally Facebook enters the dominant market of Google. I bet the social giant can do ads better, but vice verse?
> I have identified another SaaS that's doing something that I could build into my product but do not care to do

Is your product doing something they they could build into theirs? It's something to consider before approaching them.
Doesn't www.tripit.com do exactly this?
Yes, in practice (ignoring disasters), coal plants release more radioactivity into the environment than nuclear plants. But that doesn't change the fact that the original title of the article, and the article itself, are phrased in a wildly misleading way. It suggests that the coal ash is more radioactive than the actual nuclear waste itself, and that's totally not true.
As a "joyriding dipshit," I can assure you we're not spraying you with lead. General Aviation is moving away from leaded fuel in general. In fact, Shell recently announced an unleaded alternative to AvGas that can be used in a normal engine without issue. No new equipment required.

I'm curious: what about other careers? Are there fewer categories? Do they all do the same type of math? etc.
If it enables them to watch content, period, people will find a way.

The argument is honestly irrelevant. Popcorn time is a UX leap from what was previously possible. There may be another UX leap in the physical device on which the content is played, but you can't ignore the moon landing just because it didn't happen on Mars.
They could build it. However, we are currently the dominant player in the field. It took us over a year to build it with a three man team. It's also a data intensive SaaS and it would require that same amount of time to collect the data that's needed to make sales. I think it's 1 or 2 people running other other SaaS.
MSVC supports C++ instead (AFAIK, it has most of C++11 implemented), while CompCert doesn't compile C++ at all.
Ten seconds seems like an incredibly liberal estimate. You need a pretty decent "margin of error" reserve. I'd wager we're looking at something more like 30-60s of fuel during the last stages of landing, at least. So let's call it something like 2-3% of the fuel.
> - It's almost like Sony didn't even have one UX designer working on their project. It will do idiotic things like when Hulu opens, create a modal dialog that says "The internet content is ready" and I must click OK to proceed.

This really sounds like a design failure + rushed development. It sounds like the sort of thing that you would throw in during rapid development with the idea to replace it later, only it never ends up on a TODO list, and there is no one looking at the 'big picture' to make sure that these things are caught.
At the risk of getting downvoted for what could be a humongous display of ignorance, although the theoretical grounding of the article seems interesting, I fail to see how any of this can get applied to "real-life" applications when this is basically ten pages of content to get to apply this to addition operation and for other problems which are, for most day-to-day practice, already solved quite succintly.

Perhaps it's just me, but it seems like an awful lot of conceptual baggage to do things that can be expressed with much greater simplicity and without resorting to concepts that need multiple years of expert knowledge of the language to get this "elegance". And i understand the theoretical elegance, it's just that I have to ask myself if this truly makes an actual difference in code style, simplicity, and clarity of language.

Levitt and Dubner wrote down a number of interesting theories about lots of things, but I think they overthought this one.

The crime rate rose and dropped pretty neatly along with the proportion of young men in society. The median age is much higher now than it was 30 years ago. Crime, especially violent crime, is a young man's game.

Perhaps they are right and roe vs wade was one of the factors in raising the median age, but it seems that people today want smaller families, and have more control over this than a generation ago. You can't assume that if a woman has an abortion, a miscarriage and two kids over her lifetime, she would have had four children if it hadn't been for the abortion and the miscarriage.
Absolutely. To me, fighting over whether coal or nuclear is worse, is like fighting over whether Hitler or Stalin was worse. We need to get rid of both, although coal is definitely a lot more urgent.
They also tested the new replacement to grasshopper called Falcon 9R Dev

For those searching for a TL;DR of the article, here is a much shorter blog post by the same author talking about the different kinds of evidence supporting the thesis:

One quote:

> There are now multiple rigorous studies using different methodologies that demonstrate this correlation at the city level, the state level, the national level, and in different countries at different times.
I don't hate general aviation at all. But I do hate the segment of the AOPA who are basically an offshoot of the NRA, the 100LL-from-our-cold-dead-hands faction. It sounds like you are an aviator so you must be familiar with the people I am talking about.

It's true that if you average the consumption of avgas over the service of the planet you get a pretty small number, but that's no consolation to the family at the end of the airfield who actually gets all of that stuff deposited in their back yard.
After a handful of times of getting burned, I've come to interpret any official executive statement on values or culture as a sign that things are seriously screwed or about to become that way, and that it's time to bail out.

To me, culture is something that happens organically and not via directive. Leaders can shape company culture but only through their own personal demonstration of it and not by decree. Once I hear someone saying "this is how it shall be henceforth," I'm gone. They're either hopelessly naive or trying to construct a happy edifice while behaving badly.
Writing a specification for sorting sounds a lot easier than actually writing a sorting algorithm. Though admittedly I have never used a programming language where I could try to encode this property in a type.
I'd be very surprised if less than half the bookings were for sex, amateur or professional.
Does anyone have a short and sweet one of Piketty's most profound findings:

the data reveals a deeper historical tendency for the rate of return on capital to outstrip the overall rate of economic growth, leading to greater and greater concentrations of wealth at the very top.
quote from NY Times article:
www.nytimes.com/2014/04/19/books/thomas-piketty-tours-us-for-his-new-book.html

Why does the rate of return on capital exceed the rate of economic growth? Isn't this just indicative of an asset bubble? And bubbles don't last forever. Or do they (if the Fed is always bailing the banks out)?
Saying it's converging on a Lisp is flexing a little bit of artistic license. It's fair to say C++ is becoming increasing accommodating to whatever you want to make of it if you're willing to compromise and roll with it. For sure, it's one of the very best and most practical languages for writing extremely efficient implementations of algorithms.

I highly recommend watching Alex Stepanovs A9 lecture series, "Efficient Programming with Components" [0], where he covers the humble min() function, and variants thereof, for at least ~20 hours. During this time he also takes a minor digression in to writing a memory pool for linked-list nodes, while pointing out similarities in the design to a Lisp. It's extremely 'instructive', as he would say, in understanding how he writes C++ code. The sheer amount of code will horrify you, it may even seem unproductive, but I think his objective was really to get everyone thinking about the beauty of the algorithms and the details rather than the objective. His concern for performance, correctness of code, and composition of algorithms is interesting and something I haven't seen presented in real time, in C++, in such a manner before. One example for instance, are occasions where he insists on writing functions backwards, from the return statement up.

If you want a higher level overview on his opinions of C++ and programming etc. The less intense series, "Programming Conversations" [1], is worth a more casual watch.

They used it because it made content consumption possible. They did anything they could to get the content. There were all kinds of barriers: cables to connect your stereo (everyone did this), CD burning, file management, media players, corrupt files, bad connections, port forwarding details; the truth is it wasn't a great experience, it was simply possible for the vast majority of people to execute, and that was good enough.

That's wonderful, but get back to me when the FAA (or the EPA) actually outlaws 100LL. Offering unleaded gas at airfields, even if that happens, won't solve the problem of people using leaded gas. Hell, there isn't even an FBO anywhere around where I live that offers an autogas pump. It's 100LL or JetA or nothing.
Getting rid of lead in gasoline is important because we consume a LOT of gasoline. We don't consume nearly so much Avgas -- it's about three orders of magnitude difference and as such it's a drastically smaller pollution source: http://en.wikipedia.org/wiki/Avgas#Consumption

If you're truly concerned about lead in the environment you'd be best served going after old structures with leaded paint -- not Avgas.
If you add water to Magnesium Chloride Hexahydrate (a powder at room temperature), you get more water than you had before... This will work with any hydrated salt...

For instance, dissolve 150 grams of fully hydrated magnesium chloride in 100mL of water, and you will end up with 185mL of water.
Why? Just because you use less coffee? That's not a good measure of coffee quality. Good beans, good grind, clean water are. I actually prefer the coffee from a french press, having grown accostumed to it over the years. If you use a coarse grind, there's little grit and residue, and all the tasty oils are still in there.
> Suppose I tell you 3 + 2 = 5 and 2 + 3 = 5. Did you learn anything non-trivial about + from those two examples? Did you learn that x + y = y + x for all x and y or that x + (y + z) = (x + y) + z? You can sample as many points as you want and you'll still be no wiser as to how + behaves and how it interacts with * or that the implementation of + even respects any of those properties. If you're going to put in the effort to generate unit tests then why not go a bit further and formally verify the correct functionality?

One could take the middle road and express commutativity, distributivity etc. through invariants and use a fuzzy testing tool to generate tests for it. Generating 100 tests sounds a lot better than a single handwritten one, though of course it's not as good as actually proving it for all inputs.
You're preaching to the choir in my (personal) case, but what specifically do you have in mind?

The problem is that while they charge a flat rate monthly, that doesn't include repairs and one-off charges which get passed on to the landlord. Maybe doing a combination of property management and home warranty would be valuable, but neither industry has the best reputation IMO.
Also, not all nuclear reactors must be of the currently most common (obsolete) design. We should invest more in MSR reactors that could generate power from the waste BWRs and PWRs leave.

Thorium, while no panacea, also should have a larger role in power generation.

This always amuses me. Crime in the US was rising... until the mid-90s when the twin powers of the ridiculously high incarceration rate j-curved and the internet bringing all sorts of indoor distractions happened.

I mean, who would have thought that teenage delinquency would be reduced by distributing computer games, giving them something to do rather than wander the streets being bored?

And if lead really is responsible for 90% of the crime, as stated in the article by the chief propagandist, then before leaded fuel was around, crime should have been negligible - and it clearly wasn't.

Edit: perhaps the lead-in-your-fuel people should debate against the concealed-carry people, since both of them claim absolute ownership of the decline in US crime from the mid-90s onwards.

No, you are exactly right. The C community and its progeny has, over the years, dug itself into a deep, deep syntactic and semantic hole. It is now coming to realize that the Lisp folks had some good ideas after all, but because of the sunk cost fallacy the C folks are unwilling to just back out of the hole. Instead, they keep digging the hole deeper and deeper in the hopes that some day it will emerge into the light. C++11 is interesting in the same way that Brainfuck is interesting: it's remarkable that you can take such a horrible mess and make it do cool things. But it's just a parlor trick, kind of like escaping from a straightjacket while handcuffed. It's challenging, and it requires skill, but at the end of the day you're in the exact same place as if you'd never put the handcuffs and straightjacket on to begin with.
I don't think it's that people pretended it didn't matter. They intentionally sited the pollution in neighborhoods full of Those Other People. Take, as an example, my town of Oakland, California. Are there freeways all over West Oakland? You bet. Are there freeways in Piedmont? Of course not. Rich people have historically been pretty careful to keep the freeways out of their neighborhoods. Airborne lead doesn't get very far from the freeway before it hits the ground.

Your overall point is right, though, that mid-20th-century motorist pretty much behaved like an oblivious jerk for decades.

Market size is definitely something that would need to be considered. I agree that the bread and butter would be the upper middle class, but I think you may be underestimating how large of a market that is. There are 115 million homes in the US, with 20% of them earning 100k or more [0]. Only a negligibly small percentage of those make over a million which is the lowest I think you'd have to make to justify the cost of a personal assistant. I also think you're oversimplifying the problem and making an unsafe assumption about how many people have this problem, but I could be wrong about that. It would need to be tested.

House cleaning should probably be an optional add-on, but I think you're underestimating how big of a market that is too. Approximately 10% of households seek outside help with at least some of their household cleaning chores.

Very little is obvious from looking at that code. I'm sure nonetheless that someone can and will deduce the format and produce workable dungeon files, but whether they have any resemblance to the originals is something only Richard Garriott, if anyone, can answer, which at best severely complicates the "faithful recreation" rule of the contest.
If I were you, I would hesitate to assume a respected economist has no credibility, at least until I had read the paper. What is more likely: that he is trivially wrong, or that you have failed to understand some facet of his argument?
Will formal verification ever be possible for systems composed of a bunch of heterogeneous components working together? I'm thinking of a web application, where the software's behavior depends on the interaction of client-side scripts, stylesheets, server-side programs, databases, caching layers, and probably other components, all operating in the request-response cycle that fragments behavior into a bunch of separate runs of the various programs.
Cool that you agree. Are your projects structured similarly?
Culture is a perversion. It fetishizes objects, creates consumer mania, it preaches endless forms of false happiness, endless forms of false understanding in the form of squirrelly religions and silly cults. It invites people to diminish themselves and dehumanize themselves by behaving like machines.

Culture is not your friend. Culture is for other people's convenience and the convenience of various institutions, churches, companies, tax collection schemes, what have you. It is not your friend. It insults you. It disempowers you. It uses and abuses you. None of us are well treated by culture.
