I conjecture that almost all those experts would reply "no"

Have you asked even one? Have you asked any experts at all? This is what is so puzzling to me about this line of questioning--is the question actually prompted by acquaintance with the subject, or is it of a piece with doubting any other scientific claim? What if the projection is correct, even though you have trouble believing it? I have very little trouble believing the projection, having a mother born in the 1930s who has passed her eighty-first birthday, and having an aunt (her older sister) born in the 1920s who has passed her ninety-fourth birthday. Plenty of people from much earlier birth cohorts are already living into extended old age, so what is so daring about a prediction that anyone who meets established long-term patterns of life expectancy will live into an era with more progress in disease prevention and treatment?

(In short, why have you cited no evidence whatever on this point?)

(1) the fact that the mortality rates at elderly ages has leveled off for many decades in developing countries and (2) that almost all the increases in life expectancy comes from reducing infant mortality and the spread of infectious diseases.

That dual statement suggests you have not looked carefully at the link in my original footnote 4

http://www.nature.com/scientificamerican/journal/v307/n3/box...

(Nature's repost of a chart originally available at the Scientific American website, but a dead link there now), in which it is shown that life expectancy has been increasing steadily at ALL ages, including old ages. You really need to read up more on this, or it's hard for anyone to discuss these issues with you here. You are very careful to speak factually on other issues here on Hacker News, so this is taking me a bit by surprise. Do you know of any experts in this domain at all? Whose writings do you recommend?
I know it was meant as a joke but some people click first and think later...
I saw a news show on ZDF yesterday and they actually recommended using an email provider that has 2 factor auth with "some code on you mobile". I guess no non-geek understood it but I was still shocked. Usually they just say you should have different passwords for different sites.
Isn't this basically what we did some 10 years ago with a hidden, slowly loading iframe? It was widely known and used then, I suppose the technique became less important and forgotten with AJAX arrival and is now being rediscovered.

The only problem with this is c10k - you have to have something writing to the socket and this "something" was basically a process in most cases. It's a great fit for async things like Node or Twisted/Tornado, though. And for Erlang.
> One of the biggest views I see in my parents and grandparents: work provides purpose and dignity, and without work, you have no purpose, and therefore, you are a failure.

Well, it is certainly good to do something good for society. But it doesn't necessarily have to be paid. Plenty of volunteer work might give more purpose and dignity than some of the more meaningless and tedious jobs.

But it turns out that, according to Dutch law, it's sometimes possible to be banned from doing specific kinds of volunteer work if you're unemployed. If it's something that could be a paid position, you're not allowed to do it for free in you receive unemployment benefits. No, you're forced to sit at home and do nothing.
Really sad to see Brendan go, I work full time as JavaScript dev. So to a certain extent I owe my livelihood too him. Really sad to see him lose his livelihood. Sad for Mozilla too, in their time they did a lot of good. I am thankful for the work they did in setting the Internet free from IE.

I don't believe in the kind of freedom Mozilla now stands for. I do not know Brendan's religious views. But I am a Christian, and as Christian I am opposed to gay marriage. I could not change my view on gay marriage without abandoning my faith. I could not read the Bible with any honesty and say it supports gay marriage. I cannot apologise for my view without apologising on God's behalf. Those demanding an apology from Brendan are perhaps in reality asking him to renounce his faith. By asking Brendan to step down, Mozilla has made a statement to me that as Christian that I am not welcome in their community. And by extensions nor are Muslims, Jews, Mormons, JWs etc.

Is Mozilla destined to become an echo chamber for those who support gay marriage? Is freedom just freedom to agree? Sadly whoever becomes CEO now is now second best on technical merit.

Hi giarc,

Actually Sy and I (2 of the 3 co-founders) met on HN after a similar post (like 6 months ago?). It wasn't the one you're talking about, but had a similar theme.
Your math is a little sloppy. Nothing necessitates that "3 times as many" users on a platform equal more revenue than another platform.

So, if iOS users overspend Android users more than android_user_count/ios_user_count times, iOS still offers more revenue.

Average spending and profit margins count as much, if not more, as raw user count. The same way that the Mac, say, has around 15% of the laptop market share, but takes home around 80% of the laptop market profits.
Agreed. Other advantages:

A dedicated device means everyone in the household can use it without the friction of having to help everyone find the app and register with the same account.

People without phones (like kids) can use it.

It's designed to sit on the kitchen counter or hooked on to something. That physical presence reminds you to use it when you're in the kitchen, where an app buried on the last page of the home screen is easy to forget.

The camera-based barcode scanners like the one built into the Amazon mobile app are significantly more difficult to use than laser scanners. In a grocery shopping context, shoppers will purchase dozens of different products and every bit of additional frustration and delay matters.

One issue with the website: the hero image is really bad. The background is blurred out so there's no context and there are no other objects in the frame so I have no sense of scale. If there was like an apple next to it or something, and you could see it was in a kitchen, that would be so much better.
Have you used game engines before? If not, pick one, and use it to make a game or two. Then you'll know what you want/need in an engine.

Most game engines are amazing and you could rarely go wrong. The trick is that you should not compare tools too much. Go make the game. Use whatever. Be awesome.
With bipolar stay well away from mind altering substances unless its under professional supervision. The combination of an already delicate brain chemistry, recreational drugs, and quite probably a cocktail of mood stabilisers and anti depressants isn't a pretty sight.
Exactly, that is an excellent analogy.
I like the simplified dedicated device for creating a low friction experience, however one downside of having this as a separate device rather than an app on your phone is that you are more likely to loose it, forget where you kept it, etc. etc.
If you're good with math and interested in machine learning, I'd recommend checking out Theano's Deep Learning Tutorials:
http://deeplearning.net/tutorial/

Theano is a python library that basically compiles graphs of mathematical functions into highly-optimized C code. For computationally-intensive AI applications (ie, all the fun stuff), there's nothing that I've found better than Theano.

If you work through the tutorials (I re-wrote each example from scratch using them as a guide), you'll get a pretty good feel for how to use it.

I would strongly recommend Andrew Ng's coursera course on ML as a starting point, though.
Love it! I started to get pissed off at the beginning then as I read I started to laugh out loud!

The enterprise though predominantly uses iOS for in-house apps, at least in the US.
Any SSE server almost certainly uses chunked encoding.

Indeed, if the CueCat had had specific ties to online grocers' shopping carts, there would be nothing new about Dash.
Yes, that's on our product road map.

Moms do the lion's share of household grocery shopping, and are less likely to have functional pockets than men. This gizmo is going to be hanging on the pantry door.
There's no mystery here. Everybody starts out equal before the law. To pass a law that singles out a group of people, you have to at least have a rational basis for doing so. If the state is going to have civil marriage, then to exclude gay people from it, you need a rational basis for doing so. There isn't one. The majority doesn't get to have an opinion on whether group X is deserving of the right of equal protection; it they could it wouldn't be a right.

Regardless, in the case of California, gay people could get married before Prop 8, so if you are worried about redefining marriage, it's Prop 8 that should be your problem.
He's talking about the sign up code you need to order a free device.

I'd imagine they're sending these out to Amazon Fresh users.
It's automatic (computer) speech recognition.
I hope that's a bottle opener on the top.
No, you need to click the text only link in the header or it will still try to load images and will eventually time out.
I have not used either service. What makes PubNub.com easier and/or more reliable?
Listening to a young child carefully pronounce words for the narration was a bit distracting and slightly irritating. A sentence or so would be fine, but narrating the whole video was an exercise in patience.

Lacero is not "hell-banned" or any other kind of banned. Lacero's comment came from an IP that had been caught by a spam filter. I just unbanned the IP and unkilled the relevant comments.

Has anyone else noticed that this completely rips off Hiku?

Amazon needs to scale Fresh in order for it to be more successful. On a micro level, scaling could come in one of 2 ways: (1)increase order frequency or (2)average order size.

(1) Order frequency - Right now, a typical customer likely picks up groceries when they're out and it's convenient. This very well could be on the commute home from work, later at night, etc. With Dash sitting around the kitchen, Amazon has now created a very tangible reminder in the form of the Dash device to order your groceries, rather than waiting until it pops into your mind (and possibly not buying on Amazon).

(2) Average order size - As someone posted above, it takes 1 or 2 button clicks to reorder an item using Dash. Compared to the current way of online grocery shopping, Dash eliminates a lot of possibilities of forgetting to reorder something you intended to, because it is so simple. Compared to on the PC when you may forget to browse the snacks category, for example, and you forget to order chips and cookies. Way less likely to happen with Dash.

This doesn't address price concerns, but in terms of convenience for Amazon Fresh customers & increasing Fresh orders/order size, this seems like a massive win-win for Amazon and their customers.
He previously worked against gay people's civil rights. When questioned about that, he promised that at work he wouldn't do that. But he has conspicuously avoided any substantive statement about his donation or whether he'd do something similar in the future. So there's no conjecture here, just a rephrasing.
I think the point was "so simple a child could explain it".
Since it only builds Windows Store apps for ARM and x64, and since Windows Store only supports Windows 8 and Windows Server 2012, no.
This totally reminded me of CueCat. Despite CueCat being free, it was commonly sold on ebay because it made the cheapest barcode scanner on market. Amazon dash will end up being similarly awesome for hobbiest to hack on.

That's because Wikipedia isn't a tool to learn mathematics. Wikipedia articles (on anything) are not meant to teach about a subject (in the sense of schooling) but rather to give an exposition of a subject. It is considered to be very bad style on Wikipedia to write articles that try to teach the reader as a textbook or a class would.
That sounds really neat. Do you have any links to resources or blog posts explaining how you hooked the two together? Does CouchDB support that out of the box?

Not to mention the credential waltz you'd have to do in a hypothetical app, in a home of more than 1 person/device, but served by 1 amazon fresh on a single amazon account. [1]

Or 1 person/device who travels between multiple places that are each potentially served by their own Amazon Fresh accounts. [2]

It makes much more sense to just strap one of these to the door of the refrigerator/pantry that it stocks.

[1] Entering/maintaining your amazon credentials on N devices, each having potentially-separate amazon credentials for other services. Good luck keeping that straight.

[2] Home, Work, Weekend Non-profit, Dorm, Family Cabin, etc. A college kid with divorced parents would be a nightmare usability scenario.
Here be speculation:

It looks fairly large (plenty of battery room), has no display (not sure about scanner battery usage), and transmits little data over WiFi per use. With it's simplicity, there's no reason they can't use the lowest power MCU and WiFi modules they can find.

All of these have good usability implications, but it looks like battery life was probably also a big design consideration.
This is pretty cool, I'm surprised it took so long, it isn't like making 'safe' non-polarized differential cables is particularly hard. I suppose the connector housing needs a few more wires but as the lightning cable has shown its pretty convenient.
I'm surprisingly finding myself in the opposite situation. Since my app is hosted by Azure, there's some Windows only npm modules I need to work with (such as azurecache[0]). They are just thin wrappers on top of .NET libs.

It sounds like there was more to that situation than simple depression, there are many conditions that can be made worse by inappropriately applying anti depressants. Unfortunately it seems your friend was in that situation, but it doesn't make the drugs universally bad.

It's designed with a loop so you can hook it somewhere handy. They show this in the video at 1m27s.
Do you believe that you're making a good-faith attempt to understand how prop 8 caused actual harm to people, and how Eich bears some responsibility for that harm?

For this purpose you don't even have to accept that it was a net negative; you could even believe that prop 8 was overall positive for society. Just that it also caused some harm to some people, and that Eich suffering harm as well is not some crazy unjustified notion, but can be talked about in the same way.
Too bad cybercriminals aren't awaiting the orderly notification of people before they use the information to do harm. The leak certainly isn't secret to the perpetrators.
also: We charge < 5% of your vehicle's sale price, ~ 80% less than a dealership trade-in.

While I know what you are saying reading it quickly seems like you give 80% less than a dealer. That you are a worse deal. Might want to rephrases it just a bit.
This is only remotely related, but I figured this might be worthwhile.

I was an everyday Twitch consumer, but I practically stopped watching it overnight. Not because I don't enjoy the content anymore, but because my Chromium crashes every time it tries to load Flash.

Now, while this shows how lazy I can be in this regard, this is also a great insight. Sure, I could just fire up Firefox or even try to fix the Flash issue, but this is one step too much for my taste.

From watching Twitch everyday to watching practically never, only because of this issue.

So if you spend months developing an application and say to yourself "The user just has to do the little step X to fully enjoy my work...", I'd beg you to reconsider. Sometimes, the smallest friction can stop a user.
Or, as Einstein put it, "It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience."

Rephrasing for the software world: "...without having to make appreciable sacrifices in user experience."
The title of the article sounds oxymoronic.

It isn't over, not by a long shot.

It looks like you can code. Turn your internship into a job at a small web dev company and code. Take classes part time at the Community and work your way up if GPA is the problem.

Also if you have trouble staying sober, find a program or new friends, do whatever it takes to stay sober. Future you will look back and see this as your pivot.
Why, that's hardly 20 million people!
They can get it right (figure out how to increase order sizes, order frequency, margins, etc.) and then expand; or they can expand and try to figure all of those things out.

With their main business they chose to grow as fast as possible and are still figuring out profitability. When you're selling electronics with 50% markup that works. Groceries, which have <5% margins, not so much.
I don't think that's helpful. Perhaps more along the lines of putting a flat redirect on port 80, with no content.

(It sounds like this attack depends on a complete version of the website being available over port 80)
This may be utterly inappropriate, but I just want to convey my sympathy for the loss of your son, I honestly can't imagine anything worse. You have my utmost respect for managing to carry on, and supporting your family through it.
Not to be a pedant but you're neglecting steps in your Dash algorithm that you implemented in the phone version (possibly creating a visual bias).

Number of steps to scan grocery by Dash:

1.) Find scanner

2.) Turn on scanner

3.) Start scanning action

4.) Find laptop (or mobile phone)

5.) Navigate to browser

6.) Sign in to Amazon Fresh Account

7.) Confirm and pay

I don't honestly think the Dash would provide a discernibly faster experience, but I do believe it would be the option your target demographic opts for simply because the Dash is explicitly designed for this type of task. Just because my phone can turn on the television doesn't mean I won't reach for the remote every time.
Properly used, GitHub doesn't stop git from being decentralized.
Yeah, me too... it's not an easy paper, the algorithm is quite convoluted, and it took me a while to understand... I'll add some explanation of the basic idea and my version of the algorithm.
It is not immediately obvious to me what fanout.io does from your homepage. Could you add an example?

Clients register to listen with the fanout.io CDN, then my app pushes something to the CDN, and fanout.io handles pushing it to all of my end clients?

Can I determine which subset of users receive the message, or is it "all or nothing"? Are clients able to listen on a specific topic/name?

I'd love to get more info, but I didn't see any higher level explanation and don't have time to dive into docs right now.
Without much hassle ... (welcome to development :)
Amazon is creating services and products based on observed behaviors and needs in households with multiple people. You're making claims about what other people want based on how you feel.

Creating things people want and are willing to give you money for requires paying attention to what they actually do and use -- not just what they say they do, nor how you feel they should be acting.
It seems silly that you would want new legislation in this instance. Do you feel similarly about exclusive games on Xbox/playstation? What about apps that are only available for iOS?
In fact, this one (implementing Lispy thing, I mean) seems the best to me so far. Why? Paradoxically, because it's so obviously incomplete, so it makes you search something by yourself while you read it and helps to actually understand a little bit more.

Both K&R and "Modern Approach" lack that word "Modern" very much, yet are written with undertone "it's everything you have to know about C", when it isn't. Person who doesn't know C very likely doesn't know how OS works, what architecture layers are behind the software he uses every day. He just knows somehow he wants to learn C, but doesn't really understand what C is, yet he knows that virtually everything is written in C, and "everything" usually doesn't run in terminal, but processes and produces sound, images, video, can have GUI, use some external devices, run in parallel, run on GPU. Also, it's pretty obvious (especially if you've used some language like Python already) that nobody writes everything from scratch these days, but there're many libraries that proved to be useful.

And stuff like branching and cycles seems to be pretty obvious even for somebody without coding experience, as far as I can judge from what I've seen so far. Yet we have plenty books that spends 20 pages to explain "if" keyword and mentions every function in standard library (why?! it's 2014, people, we have cplusplus.com now!)and covers nothing in sense of what useful libraries are out there, what are these domains where you still should use C today (because feet to meter converter shouldn't be written in C today and you probably should choose Python if there's no specific reason to use C), what tools to use for testing and debugging and such.

And while it can be justified for K&R (jeez, how old is that book!) it's just ridiculous that book that has "Modern" (well, it was 2008, but still…) in it's title covers almost nothing of what person who wants to program in C should know today. Worse, you'll see that only after reading these 800+ pages.

"C the Hard Way" is a little bit better, but still not as good as this one. This one also isn't perfect, but is the best of what I've seen so far.
