I feel similarly. A lot of people in the media are blowing it off and making it seem like it's so easy to avoid infection.

Glenn Beck made a song about Ebola with advice including "Don’t lick vomit off the street." Sure, it's Glenn Beck writing a stupid song, but I get the same reaction from other places. Stephen Colbert interviewed an infection specialist who said, "The only way to get infected is to touch that blood barehanded or smear it on your face."

Technically true I suppose, but the implication is that only crazy people could contract this. It's clearly not true. Healthcare workers make up 10% of the deaths in this outbreak.

And this article you posted isn't reassuring at all. The graph at the top appears comforting, until you read the footnote:

>The R0 is integrated over the time that a person is infectious to others. For HIV, this could be years. But for Ebola, that time is only about a week. So even though they have similar R0s, Ebola's infections per unit of time is much higher than HIV's.

So you should expect the number of cases to double roughly ever week? Super. Looking at the WHO estimates, it's closer to once a month (1 week contagious + 21 day incubation period I suppose), but that's still pretty terrifying, since 20 more months at that rate would be the world's population. To be clear, I'm not making any claims about how this will play out, but only demonstrating bewilderment at how that article is supposed to be reassuring.

I'm willing to accept the claims that our healthcare system can easily contain this, but I really don't understand the sentiment that it's not very contagious.
Nice app for iOS. On my Nexus 5(Android), I use it like this:

> However this technique relies on printing the value of the double-precision approximation of pi to 33 digits, and up to VC++ 2013 this doesn’t work

How can an IDE prevent printing a number? If all else fails, you can reinterpret_cast it to integer and handle the bits yourself?
Despite what you say about a lacking plot, which you may have exaggerated, you still call him a "fantastic author." Which is either irony or there's something to that.

It's not necessary for a book to have a great plot, to be a great book. I haven't read any of this guy's work, but Murakami has a similar "thing" going on... the plots in his books are often fairly dull and leave a lot of plot-lines unresolved... but yet the books are very enjoyable and thought provoking. It's almost like it's the atmosphere that matters, not the plot itself. Perhaps this author writes something similar?
Yes, though this particular code would not compile because one of the lifetimes is not declared.
That would be illegal, because it only makes sense to return a reference when that reference is somehow linked to the lifetime of an input parameter.

(Or when it has a lifetime of `static`, which means the referent is stored in static memory and thus is alive for the whole program.)
Here in the UK that's how many shops (and some chains that are still extant) started out.

You went into the local grocers which had a counter/hatch (think post office/bank), You told him what you wanted (or he your weekly order) and he (or usually his boy) would then drop the merchandise off at your house.

The Supermarkets pretty much paid to your corner grocer (economies of scale, later opening hours, more variety of items, the ability to do your shop yourself as and when needed and the increasing wealth of the UK (cars and refrigerators)).

It would be amusing if we went back to a high tech version of that.

What you said about the relationship between products and patents is true and worth adding to the discussion, fwiw.

I think making it an absolute - ie, there is never anything to learn along these lines - is going too far, but there are certainly a lot of patents that never see further development.

Linked for that article is "Thermoelectric Material to Hit Market Later This Year" [0]

Which is interesting. I've been thinking about using a thermoelectric generator in my off-grid cabin to make up for the lack of solar in the winter. Up here in Yukon the wood stove is burning 24x7 from October to March, and you can guarantee it's not above -10C (often -30C) outside.

I'm thinking of mounting a bunch of them near the stove for the hot side, then running a radiator outside for the cool side. I don't think it will be too hard to get a temperature difference of a few hundred degrees C. Hopefully this new material will come good on it's 5-10% efficiency.

> This is a great example of Rust's practicality and a scientific/empiric mindset to building the language.

Rust sometimes seems like the antithesis to BDFL. I quite like that they experiment, but I'm wondering how this will work out post 1.0.
My issue is not performance: I believe that you will have more coding errors due to the semantic error inherent in the variable being initialized twice. In some languages... in many languages... this is in fact impossible to even type, and the arguments why are due to semantics, not performance.

If it makes you feel better, move this code to a function that returns a single value and initialize the variable once in one place (and then mark e value const!). I actually also agree this is a better option, but semantically the if/else is clearer than the if/default, so I would not fall back to if/default over if/else.

As for relying on the compiler: turn that warning on manually and turn that warning into an error manually. (Do not turn all warnings on, as upgrading your compiler can break your build, but turn on warnings that you actively want to verify your code against and have cleared your code against (including this one.)

I will also argue that you should treat your static analysis similar to a dynamic unit test on your code: it doesn't matter if some people are using a compiler that doesn't have this feature (though that seems unlikely as I believe all major compilers support this feature) as the maintainer will, in the same sense that running unit tests sometimes requires more dependencies than running the underlying code.

Again, though, if you are very used to the if/default control flow, I can appreciate wanting to use it: I just would rather see people take advantage of static language analysis that is present to deal with silly errors, and then arrange their code to better handle high-level logic errors.
In this comment you offered the same theory about "pump and dump" that many others had over an hour earlier. It wasn't anything new. And the idea that Apple's demise would lead to the rise of Ubuntu is, well, let's just again say that I didn't (and won't) downvote you.

I can't downvote replies to my posts. I guess most people can't. Of course you can't be sure if people maintain extra accounts for karma fiddling, but I think it's reasonable to assume that most people here do not.

So in less words: the people you are replying to are (probably) not downvoting your replies.
My friend has the opposite problem--- all packages go to the apartment manager's office. And his hours are allegedly 10-5, but he leaves early all the time. She picks up her packages at an amazon locker because the manager keeps the packages too secure.
I would say sometimes you can control for this statistically. When the selection problem is exactly along the dimension you want to measure, (i.e., measure the impulse-control of children of parents with poor impulse-control, but only the part caused by angry yelling) statistical correction is less plausible.
Thanks for this. Good to know about it.
That managed to completely lock up Firefox for me. Nicely done! Think it was a combination of the scrolling page title and right-click handler that did it. Or it was fighting Pentadactyl.

UI looks nice from the video, and seems like a quality service. We're currently using ShiftPlanning, which is similar, albeit uglier, and has a few more features that would be hard to give up: discussion board for employees, ability to blast announcements to employee groups, syncs with 3rd party calendar systems, etc. Maybe you should check them out for inspiration to grow your offering.
I don't think it is another layer, and I don't think it ties you to a vendor. This is a query builder tool that produces SQL code. You then take that SQL and run it against the DB. Once you've generated the SQL, you can modify it, you're not tied to the original pipesql.

Learned using Stanford course - this is pretty standard.

Bought a book for Cocoa programming to learn Obj-C. Alright, but not a deal breaker.

First gig I offered for $200 flat rate to get the portfolio rolling, through a HN post: https://news.ycombinator.com/item?id=6382405

First app idea was actually a game, I learned what was necessary to build it (https://itunes.apple.com/gb/app/firework-flare/id513766705?m...).

Biggest challenge: going from basic programming knowledge to having to use design patterns, strange (at the time) syntax.

First, a nitpick: VC++ is a compiler toolchain (including libraries), not just an IDE.

Also, the next sentence:

So, you either need *custom printing code* or you need to wait for Dev 14 which has improved printing code.
I very much prefer the classic structure of a scientific article. In my experience, articles that do not adhere to the classic structure have other errors in their content.

This article has only examples in the "results" section but no results. Additionally, the section is the same as the discussion section. The conclusions do not only conclude but show further discussion.

Finally, I would have liked to see a verbal explanation or interpretation on why "strategies with high fitness can also have high probabilities of extinction".
It is very likely that thousands of people are going to die this year alone, because the elected officers that are supposed to protect them are more concerned with "preventing panics" than with implementing actual measures to contain and stop the epidemic.

We already have forced the moronic security theater of airport security to "protect" against a bunch of yahoos using box cutters as weapons. How worse could it get, anyways?
"Though I agree, it does sound insane. What would they stock?"

????
I would expect they are only going to stock amazon stuff.
Maybe amazon branded + amazonbasics.

Why would they stock anything else?

To me, this seems like a fairly obvious play: They have had trouble getting playing with fire branded stuff in their internet and tv-only campaigns.
People actually want to play with the devices.

Given the choice between buying space in best buy among tons of other companies, and leaving it to the whims of blue shirted people to sell their stuff, or doing it themselves, they chose "doing it themselves".

That seems sane to me.
One binary or multiple binaries is a distraction. The issue is how they talk to each other.

There already exist a single binary of what you describe, Busybox.

The interesting thing is that you could probably mix busybox and the individual coreutils and nothing would break.

This because the way they talk to each other, in steams of text via standard out and standard in, is defined and fixed. They also use those very same interfaces to talk to third parties.
I have Lync at work and have accidentally sent some kisses when talking about retirement... 401(k)
That would be incredible. I wish I knew enough to help with that sort of thing.
Because they need a way to let people play with things like fire hd, and can't rely on best buy to have their best interests at heart?

Note that sin(double(pi)) should not return zero. sin(pi) is, mathematically, zero, but since float/double/long-double can’t represent pi it would actually be incorrect for them to return zero when passed an approximation to pi.

Huh? sin(pi ± epsilon) better damn well return 0 if epislon is closer to 0 than the minimum representable floating-point value. Otherwise the processor is rounding incorrectly.

(I realize epsilon in this case is likely to be much larger than the minimum representable float, but it's not guaranteed and thus the article's reasoning is flawed.)
that's honestly what I would like to test for: sockpuppet accounts vs. hivemind. I'm okay if everyone universally agrees that I'm an idiot, but this feels like sockpuppetry to me. especially the -3 one. normally HN doesn't feel like reddit, but it's starting to.

Quite well, I'd say. Most of the big sites have a flash-free version now, if only when you're visiting from an iOS device.
Yes, which are almost as useless as the "sold x million first weekend" metrics that get parrotted by media.

If the user base increased by 50% between the two releases, they can convince 50% less people to upgrade the first weekend, and still sell more the first weekend than they did last time.
The sold x million certainly tells you some hard dollar number that is uninteresting, but it gives you no idea how popular the device will actually be, even though it sounds like it should.
There are a lot of good stories about this being posted today. Rather than make a new submission, I'll mention here another article about the same find that I saw today and liked.[1] For background information about what we knew about paleolithic art before these latest discoveries, I strongly recommend I recommend The Nature of Paleolithic Art[2] by R. Dale Guthrie, a book I enjoyed reading several years ago. Guthrie is a field biologist and very competent visual artist who specializes in Pleistocene megafauna like mammoths. He went to most of the oldest sites of surviving cave art--although, not as far as I know, to the one now described in today's news in Indonesia--and personally looked at ancient drawings on site as he studied examples of early art for his book. His book shows hand stencil blowpaint drawings and depictions of prey animals much like those in the articles in the news today. He devotes pages of thoughtful discussion to what early human drawings show and what drawing problems early artists encountered. He even mentions interesting evidence like figuring out how old the painters were by how high up on cave walls the paintings are found--it's clear that little kids in olden days practiced by making crude drawings, and became better at drawing as they grew up and could reach higher.

misleading or linkbait titles. This one is obviously the latter.

It's not obvious to me. The title is a play on words; to the extent that it misleads, it does so for effect. And not all cleverness is tantamount to linkbait. (For what it's worth, I immediately understood the title to be a tongue-in-cheek reference to Shakespeare's well-known love of linguistic innovation.)
Hi there! That's a really good question. The short answer is: It depends on your desired business logic, your product, and your customers.

>Do you pre-bill them sans shipping address and then hope that they input it later?

In this DIY checkout example, your customers are charged at the time of checkout. Then you could follow up with them en masse to fill in their shipping address before you're ready to ship. This is a self-service feature https://dashboard.trycelery.com/status and the credential parameters can be pre-formed so convenient links can be dynamically created for each customer to take them right to the correct spot.

Once a customer has paid for something, the conversion of them coming back to fill in shipping address to receive it is very high.

>how many backers do you lose by not obtaining actual shipping details upfront?

Bravo. Not many people think of the flow so holistically, even though they should. On one hand, reducing inputs and simplifying checkout can give conversion rates a lift. On the other hand, unfamiliar UX can trip some customers up too. Also it can end up driving more support questions for sellers. eg, "When do I give you my shipping address? How do I input it?"

Overall, we're convinced so far that the shorter checkout is a net gain for conversion.
If you go to the local Best Buy, they're already on their way to this model. They have Apple, Samsung, Nintendo, and now Microsoft mini-stores within their large space.

Someone has already picked up on the "micro-mall" phrase. They're running a store where merchants rent display space, and they handle the cash registers and stocking for them.

Ask HN: Vagrant on Windows or OS X?
I am a front-end developer and I am about to start doing some contract work on a Rails web app. I currently use a Windows PC but I don't want to try and mess with getting RoR and the app to play nice with Windows. It looks like I have two options, I can use Vagrant and stick with my pc or I can purchase a MacBook for OS X.

I would rather not have to buy a new MacBook right now but I certainly don't mind if it would be best. My main question is, would there be any advantages to using OS X over Vagrant and Windows?
I came across this the other day which was a great read:

http://www.entrepreneur.com/article/237922

My friends and I have a catalog of android jigsaw puzzles, when we started we were manually optimizing the keywords on each individual game to attract people searching anything related to that theme - one about England we went after England-related keywords we could think of rather than the competitive 'puzzle' ones: travel, vacation, england, uk, london, big ben, all that kind of stuff which got us our initial traction. We kept that up for about our first 50 puzzles coming up with all these unique keywords which was incredibly tedious.
No, it is not pi that must get rounded, but sin(pi). So in sin(double(pi)), first double(pi) is computed, which is not exactly pi, then an approximation to sin(double(pi)) is computed, which is not exactly zero. It would be absolutely wrong to round a non-zero number to zero.
>What exactly does it kill?

Everything.

>Does it fry the whole circuit

Yes.
Consider http://www.nytimes.com/1999/04/18/weekinreview/walk-this-way...
It will fry the electronics. Ethernet is not intended to carry any significant current on the TX/RX pins. Applying 120 VAC to those pins will almost certainly cause the current to exceed the limits.

I'm not very concerned about non-interested parties (such as yourself) downvoting. mainly, I'm interested in how much sockpuppetry is actually going on. it's relatively trivial to make a bunch of posts using a myriad of nicknames (I have 5+ abandoned accounts with more than 500 karma each - lost the password to all of them), so I'm fairly certain that if a random sociopath had enough time, he could easily game the comments of a thread.
