> Also, how do you differentiate the drowning response from someone that's just bad at treading water and floats low in the water?

Watch the face, arms and legs, and water surface. A swimmer in distress has his mouth as high as possible, may be flailing a little with his arms, barely kicks (if at all), barely disturbs the surface of the water, and goes under repeatedly.

But as a lifeguard, I helped weak swimmers, and then requested very firmly that they stay in shallow water. I also took their names so I could get their attention quickly if they wandered too close to the deep end.
I'm pretty sure that's a bug in Firefox, at least on Linux. They insist on setting volume at 100% for every new stream because "what if the user had muted youtube and is now wondering why the funny cat video on another site isn't playing". See https://bugzilla.mozilla.org/show_bug.cgi?id=497164 . And of course, they open a new pulse audio stream for every browser stream. The entire situation is one bad solution after another.
We use those too and they are totally safe. The difference between those and the classic floaties is these can't come off, which I remember happening all the time with the old style.
The specific reasons for how people place value on music aren't hugely relevant; all that should matter for the label in most cases is maximising the total revenue (as for digital downloads the marginal cost is irrelevant).

I'm still curious about this: "What does it look like when an able swimmer encounters trouble?"

Do adults drown as often as children?
I appreciate that this article doesn't over-simplify the color theory -- it talks about the complete spectrum of visible light and the fact that our cones preferentially receive short, medium, and long wavelengths.

What I've come to expect from pop science is the "lie-to-children" description that our cones receive red, green, and blue light, as if only three wavelengths existed, and as if our eyes were designed to look at computer monitors instead of the other way around.
I really don't know much about these things so you might well be right - but it's labelled an equity deal and they explicitly point out that the series e was debt.

Also would it be typical to do 30m+in debt for a 50m company (typical is probably the wrong word given Ubers trajectory)?

That's a fantastic question. This is probably the right place to ask if there is pattern that can be detected from the wrist. It also makes sense to line the pool edge with lights that can change color, so the bracelet distinctively lights up the grid square of the pool where the drowning is happening, alerting the lifeguard or a strong swimmer nearby.

> Drowning is the single most dangerous form of activity for children.

Drowning is not a form of activity. It might be the single most common cause of accidental death (just checked, it seems to be, but only for children aged 1-4 [0]), but that's different than being the most dangerous activity. If you are comparing danger of activities (like, say, swimming) you would compare the frequency of the thing you are looking at the danger of (e.g., death or injury) for people who engage in the activity (e.g., deaths per hour swimming) vs. other activities.

> We're more than happy to ban guns

Well, not in America. (Whether we should be or not; firearms regulations are extraordinarily politically controversial in the US as a simple matter of fact.)

> I know, I know: swimming pools complete an idyllic image of summer, and in reality it will be a long while before it's even plausible we'd think about putting the most basic of restrictions on them.

Actually, that's not true. We have put restrictions on them, such as California's Swimming Pool Safety Act, requires anti-drowning safety measures for all residential pools for which building (incl. remodel) permits are issued after January 1, 2007.

Hi

You missed a 5th method, another (very annoying) hybrid: Advertise to everyone, maybe less to subscribers. The New Yorker is known for this model, among others.

To answer your poll (clarifying questions inline):

1. I would be willing to pay Google $30/year to opt-out of AdSense.

-Would I have to be logged in for the opt-out to work?

2. I would be willing to pay a Google competitor the same $30/year to have advertising-free results of equivalent quality.

-Where do you find another search engine whose results are more relevant? Do you mean having "non-personalized" results by default?
We need to move beyond hardware & form factors.

This is not something that any of these people are willing to step up and tell the public.

Some have moved beyond hardware & form factors.

On Weave, yeah. Not the best performance, and improving. Flannel is obviously better, and one of the reasons we're excited about rocket. That changes almost nothing for shops hoping to move to containerized architectures now. It's only for existing early adopters.

The idea that docker introduces that much uncertainty is outright fear mongering. There is a huge amount of recalcitrance in the community to do anything meaningful in the space due to a proposed risk aversion. My personal opinion is that we're all pretending we didn't write incredibly delicate and brittle provisioning and monitoring code with very dated tools.

Many people I know, and more than a few I respect, ultimately point to all their provisioning shell scripts as the ultimate reluctance to change things. "It will be really hard to migrate and test these! Generating them is a pain!" Of course, the elephant in the room is we all knew this going into it and we all know we SHOULDN'T have been doing things like generate shell script execution and using git to provision on production boxes and w/e other hacky shit we've done.

Of course, what we have is not any one thing but all too often an amalgam of spare hours and quick fixes and patches laid over some existing provisioning system like salt, ansible (or just a whole shit ton of puppet work).

Counter-intuitively, suddenly everyone has become a devops luddite when it comes to a genuinely novel approach even though container abstractions have already proven themselves at scale. People hem and haw and suggest that somehow it's not ready for production. Meanwhile major players in the space are already using them, even for core services, with excellent results.

Lightweight containerization has been used to solve this for awhile now. Docker as a product and initiative is relatively new, but to suggest it was the first example of a container engine used in production ignores the actual history of lightweight containers.
I was surprised Android wasn't a higher percentage... Look at it this way:

78% of the current smartphone market is Android, 18% is iOS. [1] (4.3:1 in favor of Android)

According to the article, 38% of hackathon devs are interested in Android dev, and 22% are interested in iOS Dev. (1.72:1 in favor of Android)

From this perspective, desire to develop for iOS is MUCH higher than market representation, meaning that (as I read the numbers) comparatively, Android appears to be the weaker choice -- and that amongst hackathon developers, iOS is far over-represented compared to the market as a whole, as I assume most at these events use their own devices.

I do not know for sure. My believe is, that kids at that age sometimes simply do not know what they are able to do or not. They watch others, as they climb down the ladder and they just imitate them, somehow expecting the same outcome. This boy for sure was not able to swim, but he probably didn't know it. He perfectly copied the behaviour of other people entering the pool and then was maybe completely stunned that he did not float, but sink, I guess. He was in a age where most kids in Germany are confident swimmers and like to dive as well. It was not obvious to us that something was wrong, because his behaviour was so confident. He did not hesitate to climb down, and there were no sudden unexpected movements when he was under. I mean, we did not watch him specifically and guessed whether he was in trouble or not - he was just behaving just like any other boy. And you do not press the stop watch when a kid enters a pool. It just took some time until our subconscious minds shouted "something is wrong - it is too long!".

He entered the pool, face to the stairs, hands on the rails, continued to climb until the ladder ended (with his head already under water), released the rails, and sank, vertically, until the bottom. It was not a very deep pool, maybe 1.70m or so. He seemed to stand there, as if trying to see how long he could keep his breath. And when he shifted out of the upright position it became obvious that he was in trouble. A man standing next grabbed him, pulled him up, saw the boy was unconscious, started to shout for help and within seconds the boy was out of the pool and the lifeguards took over.

Moreover, Docker / Kubernetes aims to solve the problem of building services that can easily scale to hundreds of machines and hundreds of millions of users, "Google-style".

That's great, if that's what you need. But most people aren't building a service like that. HN, I believe, runs on one machine, with a second for failover purposes. And HN still has many, many more users than typical company-internal services, community services, or at the extreme end personal services.

When you aren't operating at absurd scale, "Google-style" infrastructure doesn't do you any favors. But the industry sure wants to convince us that scalability is the most important property of infrastructure, because then they can sell us complicated tech we don't need and support contracts to help us use it.

(Disclosure: I'm the lead developer of https://sandstorm.io, which is explicitly designed for small-scale.)
We're replacing a very nice custom SCO Unix backend developed at my work from 1980s onward (drops users into custom shell, multiple programs execute in the user context, leverages all the nice features of *nix) with a purchased desktop Windows ERP application and it makes me so sad.

Literally we will move from having 1 to 2 admin who can manage 300 users, decades of automation, and totally instantaneous program execution (in C) with heavy user load on a single server to distributed, client based programs running on separate machines that all have to be patched, updated, troubleshot, etc.--(and the 5 person support team that has to go with it), communicating with a central program server and separate DB servers, etc.,etc., all because the console application is "too old looking".
I agree, and would enjoy a thoughtful discussion as to why my stack doesn't work and why I'm an idiot. Instead, it's just been countered by 5 bland rebuttals and a debate about whether or not I am an idiot and if I should be referred to as such.

Not sure what you're implying either, but you can tell in my comment, I never came out of the gates saying "This is the best way!"

10 Content Promotion Tactics from the Pros
Sometimes people need to know they're idiots without the person calling them an idiot having to tip-toe around the issue. Just like how some children are smarter than others and could actually benefit from ring labeled as such, put in a separate environment and given advanced problems to work on instead of lumping them with the rest of the herd. Just like fat people should be told they're fat and pay a premium for a seat on an airplane. Hell, if you look fat they should put you on a goddamn cattle scale and make you pay extra.
But that's the distinction between contractor and employee, right? A contractor "contracts" for work, i.e. they negotiate the terms and prices individually. An employee is "employed" - their employer tells them what to do and gives them money in return. That's why two of the main tests in contractor-classification lawsuits are "Can the contractor set prices?" and "How much control does the employer have over how the work is done?"

Perhaps going from independent contractor to proper employee can be an earned upgrade? Those who show consistent performance could become eligible for benefits like health coverage, auto repair co-payments (if Uber, for example), and a preferred listing for customers. This way people who are committed to making a living in the sharing economy can coexist with the real independents who only participate to make a little extra coin.
Sorry, I am not a native speaker. German. Will fix the comment, so everyone can ease off again...
I don't see how pages transition is trying to emulate native apps. It still falls under the paradigm of accessing a resource at a given URI, which is what the web is. Personalizing the way the resource is loaded by the client and displayed to the user? That's just cosmetics we should definitely care about.

Currently, the most popular way of implementing "native apps" in the browser are Single Page Applications, which breaks the web paradigm and hence have practical drawbacks such as the inability to open some resources in a new tab or to bookmark them. One motivation of SPA is the fact that loading a new webpage produces a blank intermediate screen during downloading, which is lame, especially for pages which are almost the same. Pages transition can change that, and in a beautiful way.

I was around four-five years old when I was first allowed into the deep pool with some float equipment. I was like a fish and liked diving. Couldn't swim though.

When I jumped into the deep pool my floating equipment was pushed off. I panicked and struggled for my life until I somehow got to the side and then managed to get up by myself. And no-one noticed.

I stayed away from deep water until I could swim properly.
I'd pay 10€/month for a google alternative. It should rank resources based on relevancy, not mixed up with any advertising or business-political reasons. And no filter bubble please (opt-out?).
So far my experience with Docker has been quite exciting, but I'm still to find a real good use case for it.

Also moving around a 700MB+ image when you can deploy some Debian package (or even setup a virtualenv, I do mostly Python), sounds a waste of resources. Add to that that moving volumes around is still an issue and... well, Docker has a lot of potential, but I doesn't fit very well in any of the projects that I'm involved in.

Ask HN: Website owners, how do you ensure abuse complaints are directed to you?
I run a number of small web services, for my own amusement and to collect some pocket money. I tend to use my own virtual servers, as it's more cost effective, gives me more control and freedom.

Some of these websites allow people to submit content, much like a plain old discussion forum. It's rare to have a day when no undesired users post spam, or even worse, links to malware, phishing sites, and the like. Such content is obviously against the rules of my websites and of the server companies and domain registrars I buy from. But automated filters only go so far, and I can't stand looking at everything that is posted 24 hours a day.

On the websites I always mention that, to report abuse, one should send a complaint to abuse@...the respective domain, as is common practice. Complaints rarely arrive in these inboxes... but in the last year alone, I already had to deal with getting one domain name almost taken away from me and one server momentarily suspended.

Apparently, complainers like to direct abuse complaints to the owners of the IP addresses (i.e. hosting companies) and to domain registrars, ignoring the abuse reporting tools I have set up. The latter then suspend the services in question right away, sometimes without checking that the complaint is still valid (in one case, the infringing content had already been deleted when the service was suspended!).

Maybe I'm missing out on some best practice for receiving abuse reports (searched and found nothing). I suppose that bigger sites avoid these issues by having more people monitoring for abuse, or better filters, and that simply by being better known their hosts give them a different treatment - otherwise, just about every big website with user-contributed content would be going down every three days because some security company caught a malware link before they did!

So, dear web service owners, how do you make sure abuse and ToS breaches are reported to you before they are passed "upstream"?
Thanks for reply.

1. Yes, say logged in with Gmail.

2. Say, results which are made by both robot-algorithm (like Google) but further refined with a human intelligence (curators).
To be honest, a kid who gets into deep water with a floatation device and then falls off and notices it cannot swim shouldn't be rescued. Such stupidity should be given no opportunity to procreate.
It’s two days if you live in the US. I don’t, so the CD will have to travel for weeks to finally get stuck at the customs in the airport—and CDs are much more fragile than MP3s or FLACs. Moreover, I don‘t have a single device to put this CD into.
Sure, but the level of responsibility required by the user as a curator doesn't seem like it would hold past a critical mass. The insane amount of reposts that Buzzfeed-esque garbage gets just isn't all that encouraging to me. Short of the decidedly undemocratic method of only counting a certain group of users' ratings, I'm just not confident it would change things at scale.

Stop working 15 hour days. That's just stupid and grossly counter-productive. Work your 8 hours, then go home and don't think about it.

Your brain needs time to absorb, process, and synthesize. It can't do that if you're trying to force-feed it new information faster than it can handle.

Take some time to write a couple tests against the code, to make some small refactorings, etc. If you still feel overwhelmed or underwater, talk with your manager and just tell them the code is a pile of crap (if it really is). They don't want to hear it, but they might cut you some slack.

> What do people usually expect drowning to look like?

Head erect, more splashing, perhaps a cry for help, and above all, someone who thinks and acts like a human being. You can't tell from the site, but a drowning swimmer is a wild animal. If you have to approach at all, approach with extreme caution and with something to extend your reach.

It may be you aren't surprised because the premise of the site is to identify people who are drowning. You know it'll be happening within a minute or so. In real life, it'll happen with small probability in the next few hours. It's a lot harder to spot under those circumstances.
If I remember correctly from my AIX days (a while back, admittedly), LPARs are more like VMs than containers. Though you are still correct... virtualization goes back decades!
I agree Google should return the best response to your search and not cut things out for bargaining points, but "dumb pipe utility" is incredibly off.

Nope, we were talking more about the ability to generate electricity for an electric plane, right? Battery technology, or something else that can deliver electricity.

Of course, 50 years from now we'll have commercial scramjets:

So, progress will be made on many fronts.
I'd like to see a source for the "similar density to DRAM" my understanding is that it's an 8F2 footprint, and scaling it down to small process nodes is still problematic, even with spin-torque transfer.

All that being said, there are people who make the exact same claims about RRAM as you quote for MRAM, which 3d-xpoint appears to be.

Also note that you can buy MRAM parts right now, which are replacements for battery-backed SRAM, and are more radiation resistant than SRAM. Densities are fairly low though.

To me, this site addresses one area of our common knowledge where generally the media has really let down the collective good.

More and more, we live in a reality which is finely crafted to hold our interest and to live up to and satisfy all of our preconceptions. More and more, I meet young people whose fundamental outlook on the world is distorted by such forces. True reality is much subtler than we are, and has a habit of breaking with our preconceptions.

Most of the training we receive accidentally online caries the underlying message that we should just go along with the majority or be quiet and not speak up.
