combo of a n^2 and 2^n function--i think non-US english speakers call it a double-exponential function.
I think he was using that word not as a technical term, but as a way of saying "even faster/sharper than exponential". I.e., hyper- (the prefix meaning above) + exponential.

Certainly O(N^2) is not at the top of the food chain -- for example, it is beaten by O(2^N) or O(N!) or O(N^N). All of these could, colloquially, be referred to as "hyper"exponential.

Imagine a hockey stick graph (exponential). Now imagine that hockey stick graphed on a logarithmic scale -- the logarithms more or less cancel out the exponentiation if done right, making the graph appear to be linear even though the data is exponential. Now, imagine data that, even when graphed on a logarithmic scale, still looks like a hockey stick. That is hyperexponential.

And I think I just proved Sam's point -- that it is hard to visualize/grok.
This is pretty badass. I'm assuming unseen words are really what's left to work on. If you ensemble this model it with one that uses the same ideas but generalizes outside of specific terms, you might be able to get there. For instance, generate a matrix that represents n-gram word sequences as each word's part of speech and semantic category. When making predictions on unseen words only, you then can use those values to help guide your prediction. You could use cues in phonology and morphology to predict the unseen word's semantic category. You could build off that value with cues from morphology and word ordering to predict the part of speech of the word. Once you have that, and the information for adjacent, existing words, you might be able to make a more reliable prediction on even hapax legomena.
Diamond ring is purchased as a show of both wealth and commitment. The recipient is left to judge- if the giver is very wealthy, it is clearly not a strong sign of commitment. If the giver is very poor, it is clearly a strong sign of commitment.
"90% of it is your effort in either case."

Even so it's not that simple. If you see your parents - and all the 'mature' people in your life - doing things a certain way, then that it is the "right" way. If what they are doing is complaining how they're ont getting what's rightfully there's (vs working to make it something they earn) -- then you're going to believe that too.

In order to be able to put in the effort required, you first have to have your eyes opened to the fact that there are better ways of doing things than what you're living with every day. WOrse, you have to accept that the people you've been looking up to may be wrong about important, fundamental things.

That hurdle - that awakening to possibility - is so much bigger than any of the rest of the effort required, because people don't generally know what they don't know.
The prime mover has been an issue for quite a while. I particularly like one of the earliest suggestions, namely that which moves itself is immortal, though as an answer it creates more problems than it solves.
That is definitely be something plausible. From what I've seen, there's a lot of work at the moment in trying to write languages and toolkits to automatically target hetrogenous platforms - which this could be slotted into nicely.
Or the more obvious conclusion, which is Wired don't know how to read a paper, and nowhere in the actual experimental section do they say they pumped down the apparatus when they were actually testing.
I remember seeing pictures from that video in a book that I once owned. Calling it "treasure chests" is a bit overly optimistic. I'd say "square shadow". I concur though that, whatever was there (if there even was anything to begin with) has long been destroyed now by all the treasure hunters.
I know, right? "Sexy Taxes" isn't really a thing.
Yes, you're probably one of the only ones. The ability for Twitter to allow people (and machines) to quickly share information and allow it to go viral has certainly changed the world. The fact that the instant anything happens in the world there is a record of it on Twitter speaks enough about the impact it has.

Because insurance companies (or any profit making company for that matter) do not like to decrease premiums in some kind of automated fashion. They want you to work hard to get that reduction even if there is one possible.

Now, about your car being new vs old, that part is usually covered by "Comprehensive" insurance. It applies only to your car. If you think your car is too old and of not much value, don't buy comprehensive. It is optional unless you have leased/financed the car. If you own the car outright, then you can get rid of comprehensive if you still have it on your policy. Note: I don't know if all states have same laws but generally, this is the case.

The part of insurance where you usually don't want to cut corners is the liability insurance. That is, what happens if someone else's car or life/health is damaged by you.

The emdrive is being tested by NASA staff, who did not invent it. That alone is a very significant difference from the ecat, which was only ever demonstrated by its creator.

Now NASA is still probably wrong, but if so, they are innocently wrong. They wouldn't gain anything by faking an effect.

If anything, they are getting heaping abuse for reporting anything at all. Which I think is a problem for science. People should not be abused for honestly trying to test surprising things, even if they turn out to be wrong.
And you are using the "no true scottsman" fallacy :-) Medical progress is also progress, but suddenly it is magically excluded from the "does progress bring happiness" equation? And presmuably it is not only medicine, it's also clean water and food, fast transport to hospitals, fast alerts of the medics (via iPhone), and so on.
If you stay in pure swift, it's much harder to segfault, but it's still possible, mainly due to the amount of objC code you interact with. Today, it's not reasonable to expect a swift programmer to be proficient without knowing objC, the way it's reasonable for a Java programmer to not know C.

The segfault I hit yesterday had to do with a CoreData API that didn't retained its argument, when I assumed it did. The bug doesn't appear when compiling with -Onone, but does appear in -O. Compiler flags are another place where Swift is still very much in C-land, rather than Java/Python/Ruby land. You still need to understand the C compilation model, and e.g. getting your ARC flags wrong in a cocoapod will still cause crashes.

To be clear, swift is a big improvement over objC, but you can't pretend it's a VM managed language.

I think that a big reason that twitter seems like a big deal is because "big media" understands and loves twitter. News outlets find twitter useful because they're news people. And they talk about it as if everyone found it as awesome as they do, but we don't.
Asset Deal of the Week: Annuity with Integrity Life Insurance
I think its more about the magnitude of innovation.

Twitter barely does anything new. It's not really that fundamentally different than a mailing list... The reason it's a big deal comes from the fact that tons of people use it - not from what it actually does.

I think things like the internet are incremental improvements as well. The internet just made communication between computers faster than, say, a person walking between them and re-typing everything. In a bigger sense, it just quickened up and made more reliable the transfer of information - just like radio, the printing press, writing or even spoken language.

The difference (to me at least) is just the size of the innovation. Twitter? Small change. The internet? Pretty huge. As big as writing? Who knows.

Just my two cents. I think how you look at these kinds of things has a lot to do with your world-view. As you can probably guess, I'm a "top-down" kind of thinker.

And I do get quite annoyed by arrogant startups "changing the world" over and over again. At the end of the day most of these things are just businesses who make small, incremental improvements to existing ideas. Very rarely does something truly revolutionary come about. That's fine - it almost has to be that way by definition. On the other hand, please keep trying, people! Just maybe show some restraint when you talk about yourselves?

I love to think about what Twitter and Facebook will be in 50 years. I find it really hard to imagine them being around other than in "internet history 101" textbook-equivalents.
> Fraud come most often from customers [...] not from merchants

That only works if you're talking about a customer buying something from an established merchant. It doesn't help at all if the merchant is unknown (and therefore has no reputation to protect), or is in fact another person and this is a person-to-person transaction.

This problem is why Bitcoin needs escrow services (which most fiat currency transactions don't need), which of course add extra work and fees on top of what should be a straightforward transaction.

> Handing over all your identity details [...] allows the merchant to steal your identity and make fraudulent charges.

Charges that the credit card company pays, not you.

I'm only okay with someone posted a useless (thanks, cool story bro...) option if it's actually encouraging a better community. I suspect this sort of reasoning is why communities often tank - assholes. Assholes who are tempted by the idea of casting judgement. In that sense, it's a disservice because it encourages an emotional behaviour over a rational one.

100% spot on. Too many features missing. The flashing procedure is problematic as well (for the ZTE "open" C you need a custom patch found in a bug report, and you have to be extremely carefull not to brick the device.)

I purchased a ZTE Open C just to try out Firefox and the internet browsing experience. You can't change tabs unless you scroll all the way to the top, otherwise the address bar is hidden. Needless to say, browsing becomes very taxing if you're viewing even moderately large pages.
If you find his tone objectionable, try to look past it. Baez is a fellow worth listening to. He makes a number of substantive arguments why this looks and smells like crank science (for example, the contradictory statements about whether the experiment was done in a vacuum). It's perfectly legitimate of him to point out some social cues that you would not expect from a serious scientist making this kind of claim.

The faster-than-light neutrino experiment gave a result, too, but in these cases the onus is massively on the people making the wild claims, and rightly so.

Curious, how "real time" can a large application get in Go by judiciously working with pre-allocated structs and slices? Perhaps if the underlying system libraries don't require much garbage collection, then you can avoid stopping the world for too long.
Seems like the 10ms pause thing provokes a much sharper reaction (at least among this crowd) than this little nugget:

"Hardware provisioning should allow for in-memory heap sizes twice as large as reachable memory."

So I know "memory is cheap"(TM) but surely a 100% physical RAM overhead for your memory management scheme is worth at least a small amount of hand-wringing. No?
Jeez man, HN what a bunch of curmudgeons. I personally love this stuff, real or not, it is a modern day treasure hunt. How isn't that fun???
AirBnb is a billion dollar business now? I thought that usually refers to revenue and not valuation, otherwise we'd call a bunch of startups without a product "20 million dollar business".

Poor you. You are only getting software, for no cost, offered with permission to use it, modify it, and distribute it for no additional cost to whom you want.

If only they would allow you to take the software and then put restriction on it. It is after all those restrictions that really matter, not the software. Too bad that adding restrictions is not included in the deal.
Thanks for posting this.

I grew up a few hours away from there, I remember hearing about the 1980s efforts on the news at the time and finding it fascinating as any pre-teen boy would. I also feel like we're due for some recent maniacs to come along and start the whole fiasco over again.
Twitter and Facebook have changed the world; I don't have a doubt about it. And not only in a micro scale, also in a macro level.

I have gone from writing letters to my distant friends, to writing them emails, to writing them facebook messages. And believe it's much easier to keep in touch with friends now that there is facebook. If I travel to LA I can go to FB and check out who moved to LA in the last few years and actually meet them. Had I been in the email era, I wouldn't have had any idea of who was in LA. This is just a minor example for how facebook has changed the world on a personal level.

When it comes to the big picture, look at the Arab uprising, it used the social networks heavily. We don't know what would have happened without Facebook or Twitter, but my guess is that not much. But you don't have to go to developing countries to see the effects of the social networks on politics and society in general. [1] This is a graph of the Spanish bipartisanship going down the drain after May 15th, 2011(15M/Spanish revolution)[2]. The movement started on Twitter, and slowly moved to Facebook.

So these "toys" are changing the world, both on a micro and macro level, and denying that is like denying that TV changed how people view wars.

Of course they do. That doesn't mean their success isn't from their hard work. If you are raised in a culture of hard work, it is no surprise that you succeed. If you are raised in a culture of hanging out smoking blunts guess what happens? Immigrants are some of the most astoundingly successful people in the country and they often start with nothing. Victimology is self fulfilling.
Why downvote if it doesn't detract from the conversation?

My rule of thumb is to upvote if the comment is insightful or has information I find useful. Downvote if it seems blatantly incorrect, mean, overly negative or is actively trying to make the conversation worse. Otherwise I just ignore it.
That for me is the greatest tragedy of this: if there ever was treasure there, its historical value would have been far greater than the value of the supposed gold there, and the historical value has been entirely destroyed in the pursuit of the gold.

Regardless of what it actually belonged to -- even a ship's manifest -- that parchment would have been valuable, and it's destroyed forever now.

To me it does, and I downvote that.

Both of those conserve momentum. Black holes receive the momentum from their Hawking radiation (but in normal space are generally spherical - it's been proposed a 1000kg black hole might be able to be balanced and fed in a reaction chamber to give thrust), and the Casimir effect conserves momentum because it acts equally on the conductive plates but in opposite directions.

The problem here is where are they getting the thrust from and what mechanism is causing virtual particles to become real? And where in the energy for that coming from? Because you're paying not just KE but also the rest energy cost to make them real with Hawking radiation.
I've only known about it for a few years but I'm fascinated.
There are no rules. However, downvoting based on disagreement lowers the quality of the conversation. Please don't do it.
I don't use the down vote button (across the Internet). OTOH, I always ensure that I up vote good quality comments which add new perspective or insights to a discussion (even if they do not match with mine).
Pardon my ignorance but how do we not have the technology to just like ground scan 300ft below the surface around the island and map it out? Like Sonar or something, idk.
I think the debate is more about HOW we should break the cycle. No one wants people to keep being poor (maybe a very very small minority), but people disagree on how effective welfare (which seems to be what you are advocating) is at breaking that cycle.

Maybe better sexual education and access to birth control is the answer?
Maybe mandatory parental education is the answer?

Should we, as a society, allow children to be born into situations where they will not be properly cared for? We usually see reproduction as a right, but should it be?

I don't know if there is really a good answer for that and I honestly don't know how I feel about it. Maybe there are better implementations of welfare that I'm not aware of, but I don't think just throwing money at the problem is going to help anyone.
The value of a piece of tech is not determined by the number of users, but by a change in the quality-of-life a user of the technology receives. Meaning "value" varies from individual to individual. Companies should focus on the individuals that they bring the most value too.

Probably what pisses people off about the "arrogance" of companies like Facebook is in their claims of bringing value to everyone (who uses their product -- and sometimes beyond). Which is not true (and is arrogant/obnoxious). Also, Facebook is not the only company to have this attitude.

Companies building something for the long-term are certainly not claiming value for anyone in the present (SpaceX is not claiming to be significant in your life now). But once their inventions (rockets, cures, transportation, etc.) are actually bringing benefits to the mass majority of humanity, then they have the right to brag.

But, the climatic 'era of benefit' from an invention usually comes after the inventors/founders have died. Edison's and Tesla's ambitions bring far more value today then they did in their time. On the other hand, Facebook will very likely 'die as a fad' within 5-10 years. In other words, the greatest figures/companies (should) appear very humble in their day.

So did Facebook change humanity? Did Reddit change Humanity? Yes, they are a temporary perturbation on the 'average state of human condition' over the grand scale of time. But, other inventions bring much longer-lasting benefits/changes to a greater number of people. Those are the inventions that people classify as truly "changing the world". Those are the inventions that should be worked on more so than the 'perturbative' & temporary world changers.

We are not seeing that. It's a reflection on the abysmal failures of humanity (in its entirety) rather than on any sub-set (Silicon Valley) or individual.

Really? Because it's a pretty great picture just by itself, IMHO.
I always subscribed to my grandfather's words: be honest, work hard, do your best or don't do it at all. It's really paid off for me. I grew up as a child in government run project apartments in Texas. I was able to escape that and do well through hard work.

I notice those around me who fail, they tend to:

-Party instead of study

-abuse drugs and alcohol

-spend instead of save

-put themselves in situations that lead to bad outcomes

-surround themselves with others who are not uplifting nor motivating

-desire some level of drama
I checked the http headers - hoping to see them serving this up with a time era webserver (EMWAC). Nope, IIS-8. Still, pretty neat.
Ask HN: How should you split equity with a part-time, non-technical co-founder?
I've built the product from start to finish over the past 10 months.

I am working full time on this and always have.

I'm paying the bills.

Co-founder is a sales/business guy background.

Co-founder has a full time job and will join full time once it launches.

I feel like much of the details discussed, although productive, have little impact on the product launch. I am focused on the immediate development and launch of the product.

I am also concerned about the part-time of the co-founder and that he is not full time.

I really love his experience and business skills but feel like this is a leap of faith, although we've worked together in the past at the same company.

I know that I need to have a co-founder but not quite sure how I can split the equity fairly for a part-time, non-technical co founder. Is it wrong to take account for the premium of a business orientated co-founder?
Yes. It's easy to argue that Facebook has changed the world, but that's not inherently good or worthwhile.

We could stand to pay more attention to direction of the impact, not just the magnitude.

Well 'games' is a quite wide concept, there's been a ton of games released through XNA which used a 'stop the world' garbage collector until late in it's existence IIRC.

So there's no reason why your typical indie style game would not be written in Go, but of course if you want to write AAA style 'push the boundaries of realtime graphics and physics', Go or any other garbage collected language is not a very likely candidate.
> And by age 28, 41 percent of white men born into low-income families had criminal convictions, compared with 49 percent of the black men from similar backgrounds.

Both of those numbers are insanely high. Especially when you realize that in the modern era of online background checks, their future employment options practically drop to zero at that point. By 28 close to half of the men from low income families were essentially unhireable for the rest of their lives. How is that sustainable for a country as a whole?
