I'll bet it was both.

I was a lifeguard, so I can speak with some authority. Both skills are necessary. Not only do you have to count and track swimmers, but you have to keep mental notes about their abilities, be aware of what they're doing, and imagine possible outcomes so you can identify and react quickly to the actual outcomes. If your attention wanders for too long, especially at a busy place, you can easily lose track of someone. If you lose track of the wrong person, well, buckle up.

Fortunately, there are usually multiple lifeguards on duty with you, you're usually on a strict 10- or 15-minute rotation with them, and one of the stations is the break room. That helps a lot.

Lifeguarding at a camp is at least 5 times more difficult than at a pool, and I suspect that's why they ran drills to keep the lifeguards on their toes. Underwater visibility is usually next to nothing. The lake is usually full of teenage boys. Access to the water is effectively unlimited. There are often a lot of occluders, such as boats and bushy shores.
When Mexico can fix it's corruption issues where any cop can be paid off with a few thousand pesos, the violence will stop. It's the same reason why we had so much violence and crime during the prohibition era and again during the 70s and 80s in Miami.

Legalizing drugs in the US will not fix this. The main reason is because the labor in Mexico is cheap. Much cheaper than in the US. Legalizing drugs will only make it easier for companies here to outsource to now legitimate cartels in Mexico.

Why do you think we still outsource to China?
A guess: this uses memristors(i.e. rram).

crossbar is a startup in the field, their site gives plenty of details about the tech.

can't we have something like those fitness bands to be worn by children while in the pool - once a person starts drowning the heartbeat and other lifesigns are changing very characteristically and that can just turn the red light on lifeguards console on.
I may sound arrogant, but I'm being honest and trying to avoid my biases.

What am I missing here? These drownings looked exactly what I expected from a drowning: someone going up and down the water, splashing in a disordered manner, unable to swim or to keep the head out of the water.

What do people usually expect drowning to look like? Am I missing some detail that should make drowning more evident to me?

We connect people to high quality mobile app development shops (mostly in India). This service is good for people who want to test an idea, traction etc. Benefits of outsourcing app dev: 1) Save your money – you get quotes much lower than domestic (US) rates. To give an idea it will cost approx. 15K USD for a tinder like app for one platform (Android/iOS).
2) Time – as we connect to dev shops where you get everything under one roof, so that you don't have to go looking for a designer, backend engineer etc.

3) Reduce risk – We only connect you to providers who have a fully-fledged portfolio on their site and will fit your budget and requirements. We encourage you to have a look and read reviews about them on the web, and only then proceed.

4) Dependability - We connect you to app development companies with more than 50 developers. This is a preferable to you finding a developer from Odesk and then him going awol just as your app is gaining traction and you need him the most.

We get a small commission from the dev shops for successful referrals. If interested please fill the form in the link (takes 2-3 mins) url - http://goo.gl/forms/KDPULvkIlB
It's not just possibly more than any previous president. Public records show that he has sentenced whistleblowers to 25 times the jail time of all previous Presidents combined. He has also used the Espionage Act more than all previous Presidents combined.
That wasn't an error, but the author made a few small errors (really, just unidiomatic phrases), which suggests he or she is not a native speaker of English:

> it was such a pure horror

> a happy end

> it did not wave the arms

> made no swimming movements with the legs

> a dozen of pools and slides

> 7 boys in that age

> not loose them

None of these are a big deal, though, and the writing was perfectly understandable.
You can actually reference any frame in the stack all the way to the top. And it has a companion "uplevel" which allows you to evaluate code on any of those stack frames. But usually both are used only with the previous stack frame. This allows TCL functions to mostly behave like macros.
Samsung had similar claims about v-nand/3D-nand, which they released on their 850 Pro series
On the infographic the subtext of "1000x faster" is "up to 100s of times faster than NAND"

Then it mentions 10x more performance with a PCIe/NVMe interface.

Still all good things, but 1000x is probably more marketing than reality.

It would have to be true that the price VISA is able to charge is in excess of the total customer benefit. But then no one would buy VISA's services because it is not worth the money they would have to pay.

If this were a drawing, total value would be a summation of cost to provide the aervice (C), price to the customer (P) and benefit to the customer (B). Value captured by VISA is P-C and value captured by customer is B-P.
This story struck me as relevant to HN because I so often see managers who seem to belong to this "successful bully" class. They leverage their natural instincts for microaggressions, superior attitude, etc., to gain social status and climb the corporate ladder, although this is less pronounced in the nerd-dominated world of tech.
The AWS pages are very heavy on marketing and light on system characteristics. It would be pretty nice to know if the characteristics of Aurora are different than RDS; for example, RDS table size and index rebuilding were a big problem for a client, and I suspect that Aurora would do better, but have no reason to believe it.
"In the US Stripe charges 2.9%. That's 66% more than in Australia. Do you think it costs Visa that much extra to process a payment in the US? No, it clearly does not."

Yes, actually, it does. Payment processors like Stripe (technically, an ISO) and its merchant acquirer partners must pass through most of their fees as interchange to the bank which issues a card. Those fees are much higher here in the U.S. versus Australia, where they are regulated.

A typical U.S. payment processor charges ~2.3%, of which the processor retains 0.5%, 0.1% goes to Visa, and the remaining ~1.7% goes to the card issuer. (This averages out card-present and card-not-present sales across all sizes of merchants, and is just a rough estimate, so no judgement on Stripe's fee level, which is reasonable for a simple blended rate for e-commerce.) All of the processor's product development, marketing, operations, profit, etc., have to come from that small 0.5% margin. (That said, it's still a good business, with 50% margins at scale.)
Most newer swimming pools in the US don't have a "deep end".[1]

When I was a kid, a bookstore nearby had a computer where you could download free software, with a closed interface. Anyway, some guys came along and were like "look, we're gonna hack this thing", at which point they started mashing on the keyboard like madmen. (The poor beeps of that abused computer ...)

And now you're telling me this is an actual thing?? My life is a lie.
Agreed. I often have second clones lying around, a main working clone and an "archaeological dig clone". I expect to get a ton of use out of `git worktree`.
It could be debt.

How does he justify being the MPAA's attack dog? Is there a significant movie industry in Mississippi that I am unaware of? If I lived in MS, I'd be pissed and demand answers from this guy. Using tax payer money with no benefit to his state.
I mentored Giovanni on the two-step allocator patch, and in the process we discovered that on Windows, page tables for all of your reserved address space are counted towards the memory limits of your process. This also affects Go (https://golang.org/issue/5402 and https://golang.org/issue/5236) which uses a similar trick of reserving virtual address space for its heap. If anyone has ideas for how to deal with this on Windows I think many people would be quite interested :)

A Standing Ovation for Plaintiffs in Data Breach Cases
What does ‘rheomode’ mean?
Over the years I have come to realize that unless I can buy something in the nearest BestBuy/Amazon, it is vapor. And also, until then, I would know how much cheaper and better performant it actually is.
As I mentioned in a related response, I do see the reasoning in the 'Steamboat Willie' distinction, but that's why I mentioned a story or a song. Those don't actually have visual depictions of Mickey Mouse...the character itself of Mickey Mouse as a concept would be invoked, and the audience's imagination would have to fill in the visualization. I'm not saying it's perfect, but it's a hypothetical avenue whereby having Mickey Mouse in the Public Domain actually has downstream artistic applications, and ones that Disney's own lawyers would hopefully look at and say, "Well, shucks, this totally skirts our protection avenue" because, well, if they're the best lawyers, then they'd be obligated to avoid frivolous lawsuits.

I think it's important for artists to continually needle and wrestle with commercial enterprises for the sake of art and entertainment. Mickey Mouse just so happens to be the most visible target, well, other than Happy Birthday. And, furthermore, I'd argue that RIAA (WB) lawyers are easily as skilled and talented as any that could be found at Disney, and if this case goes the way of the Plaintiffs, it'll show that yes, it is possible to challenge and win.

Giving up just doesn't sound like very much fun to me.

This is especially interesting considering that the birthday song is essentially new lyrics for an older melody.
Look at Google Chrome. You can’t even use any <button> or <input> that looks natively in Chrome – it’s just as native as the old Swing styles.
Uh-huh. But there's no venture capital available for merely facilitating paying interactions between people, unless you plan to take a large cut.

Uber is currently grabbing about 30% of the revenue stream that passes through it, and experimenting with ever-higher cuts.

I would also point out that the modern corporation evolved to fill a demonstrated need, and there's no evidence that the need (ability to command and control large groups of people to work together to reach a goal) has dissipated.
There are other considerations, like how stall speed and critical Mach intersect as you go higher (https://en.wikipedia.org/wiki/Coffin_corner_%28aerodynamics%...). So any plane that can fly above 60,000 feet is likely going to be a supersonic design. More drag, more heat, more complexity. Concorde had plenty of issues that had nothing to do with the power plant.
Sounds like the right way out of kiosk mode—edge cases are rarely obvious.
1 - Yes it does. This is a system problem more than a docker problem. For any relatively experienced engineer, they should be capable of realizing the logs must be stored somewhere and can plan around it.

2 - If a system dies and it has a state, then what do you do? If a dockerized process dies, and it has a state, then what do you do? This isn't some new problem to Docker. If my database service dies, you know what happens? It starts back up and connects to the persistent volume. Personally speaking, yes all of my services / systems are distributed.

3 - Most people don't need to start their services exactly at this point and then stop at another certain point (which is why I pretty much brushed over it). If they do, there's plenty of tools to do this that can also utilize docker.

4 - What if a system died? Does this mean you SSH'ing in isn't a viable option? (yes...)

5 - Yes, you love negativity so clearly this is your favorite

6 - ...? What? Do you have something more to say?

It's cute that you like to poke holes and personally attack people, but really my comment was just how I go about things on a day-to-day basis. This is coming from someone who has 6 major Docker services abstracted out running all the time across 3 environments.. all capable of being updated via a `git push`. I think I have decent, practical advice to offer for other docker-minded practitioners and just decent advice to newcomers.

Your grievances circle around logs not being centralized, easily-accessible (1, 2, 4).. You also don't outline any solutions yourself.
True, when I got the email this morning as a response, I had forgotten that I signed the petition. For a few moments I thought something good was going to be published.
Why not teach children how to swim in school instead?
I'm also a passionate hobbyist when it comes to music, but I can't disagree more.

Worth is not solely measure in terms of material gains like food and bridges. Art and music have massive amounts of cultural and entertainment worth. Sure one probably requires their basic needs to be met along Maslow's hierarchy to have their life enriched by art. But I believe it's well established the impact and relevance art has.

The problem with music being fragmented into groups of passionate hobbyists with day jobs is that you cannot reliably create high-quality art this way. A lot of the luxuries afforded to hobbyists, particularly in music these days, are gained from riding on the shoulders of the professionals who are innovating and driving the industry forward. Not to mention only a certain subset of day-jobber professions can actually afford to produce quality art or music (instruments, equipment, and/or professional services).
Some languages (particularly German) use the neutral gender when referring to children. It's actually quite jarring for me as a German to have a child (especially a generic child) referred to as "he" or "she" in English.
I've never been close to drowning from something like that, but I've definitely felt that panic set in when you start swimming for the surface and then bump into a big float that wasn't there when you went down
They're pretty clearly not saying that no solution could be better than a human. They're saying that a solution which isn't as good as a human, combined with a human, could be worse than a human without the inadequate solution, which is true.
The goal of these specific drills was:

1) To keep counsellors attentive to the specific children under their care.

2) To give the lifeguard's the chance to practice their missing child search procedures.

It was stressful, and it was effective.
Who the hell is going to buy sourceforge at this point? It's not even worth the intellectual property behind the scenes. Maybe someone like cnet who wants another distribution channel for not-quite-malware.
I'm starting a new import startup/e-store for original italian (Apulian, Campanian, Umbrian and Sicilian) olive oil aimed at the food lovers niche as my family hails from there, moreover I'm on friendly terms with some family producers.
So far the biggest issue (other than those export regulations) has been finding a decent packaging. I wanted those nice Vietri/Positano/Amalfitan ceramic bottles (http://www.ceramicpositano.com/data/images/vaso-a-collo-stre...) but I fear the cost might be too high for the buyer.
I hope someone will give a push behind MRAM which seems like a more interesting option imo.

MRAM has similar performance to SRAM, similar density to DRAM but much lower power consumption than DRAM, and is much faster and suffers no degradation over time in comparison to flash memory. It is this combination of features that some suggest makes it the “universal memory”, able to replace SRAM, DRAM, EEPROM, and flash.

Ask HN: Would you ever pay to use a search engine?
HI All, inspired by debate here: https://news.ycombinator.com/item?id=9960730

There are multiple ways to monetize website's traffic:
1) advertise,
2) make users subscribe,
3) hybrid (ads for non-paying users),
4) sell or upsell goods to the users.

Two questions:

1) Will you pay to Google $2.50/mo to remove ads (both tagged and hidden)
2) Will you pay to search engine which delivers more relevant results then Google and has no ads (same $2.50/mo)?

Please explain why. Thanks!
> it did not wave the arms

The drowning did not wave the arms?
It's pretty cool- afaik, it's based off of the teensy 2.0 uC. There's actually some neat firmware that lets it emulate a flash drive at the same time as a keyboard/mouse, allowing you to deploy software on the flash drive. For that reason especially, it could be useful for anyone in IT.
A jack of all trades is great in a senior developer who's had time to learn one or more things "deep". In a junior its not much different from labeling someone as a bit of a dilettante.

Strive to be a T shaped developer eventually, but early in your career, go for being an I shaped developer.
Windows XP; the security researchers favorite distro.

There are few things better than showing up to a security review gig and have them running XP. Makes my job super easy and clients love when I rain down bugs. It's even better because we can actually write exploits in a short time frame. Love XP.
They would be expensive (compared to other swim equipment) and prone to error. I would much rather just train life guards professionally. :)
Aurora is not an RDS alternative. It is a new database engine available to use on the RDS platform.
How easy is it to tell the difference between an elevated heartbeat due to imminent drowning, and an elevated heartbeat due to having fun?

3D Printed Device Allows Smartphones to Detect Viruses Such as HIV and West Nile
The security point here is something that confuses me about the current state of the ecosystem.

The article mentions that "most vendors still run containers in virtual machines", presumably since if someone hacks an app in a container they might be able to break out of the container and access other apps running on that host. But clustering systems like Kubernetes, CoreOS, AWS Container Service, etc. seem to be all the rage these days and they seem fundamentally at odds with this. The cluster might schedule multiple containers on the same host at which point somebody who hacks one can hack all of them.

How do you reconcile this? Do people running these clusters in production typically run tiers of separate clusters based on how sensitive the data they have access to is?

I appreciate your dedication to the obvious, but the question I asked was: if software continues to grow in influence over the world, reaching the limits, what specifically will block it? The article makes the boring analysis that something growing quickly will eventually slow down. A more interesting analysis would be: what will slow it? How will software begin to wane in influence? Will something replace it, or are there limits to automation and AI that we should be considering as we move forward? It's difficult for me to see that horizon, but I am interested in what's there.
As I guy with a young child, who ditched floaties and makes him always swim with a life jacket, thank you.

And thanks for watching other people's kids. Wage or not, that job can become real rewarding, especially once you are the humiliated and terrified parent.

I do not even let my kid walk around our community pool without it on!
Homejoy is a red herring. They were out hustled by competitors and used this issue to save face/exit.

This _is_ a very new form of employment that is a mixture of two older forms. There's way too much momentum to kill it. New legislation will be enacted to cover this 3rd type of worker which will please no one except that it'll remove uncertainty so the businesses will support it.
If you ever enjoy experimenting with babies, this is how they will act when lowered into a pool. They will stand (or sit) on the bottom, holding their breath.

Having a tea party is much easier before you realize the danger consciously.
No. Kids shouldn't be around a pool unless they either know how to swim or are being taught how to swim, but that's no reason to stop trained swimmers from swimming.
That's just an algorithm, a far stretch from a neural net playing 2048.

Lots of things get created without venture capital. Giving the world back that 30% cut of every ride would be a pretty huge favor. Governments, benevolent donors, and open source developers are all in the business of doing people huge favors.
Although a very "legal" issue, whether people have "standing" (i.e., the ability to sue in court) companies for data breaches will end up having ramifications for how seriously companies take security concerns. Really interesting breakdown of some of the recent cases.
"It" is typically reserved for inanimate, non-sentient objects in English.

Besides, the story wasn't about a generic child, but a "small boy, maybe 6 or 7 years old" and was referred to with "his", "he", etc. multiple times.
Seriously? We're promoting climate change denial here? Welcome to new reddit, same as the old reddit.
just hold your breath for couple minutes (or even better - ask somebody physically stronger to "help" you to keep the plastic bag over you head to make sure that you make the time :) and i think you'll learn the difference. There is an extremely huge biological difference between "panic" and "fun/excitement".

Specifically to drowning there is also oxygen blood content difference - harder to detect from outside, yet an unmistakable indicator.
Frida: a deep dive from UI instrumentation to instruction-level tracing [video]
We have some pretty good machine learning tech out there, but I'd reckon we're quite a ways off from the proposed startup focusing on replacing lifeguards with computers even at spotting functionality, let alone the other functions necessary (retrieval, resuscitation iff actually necessary, etc.).

Sure, someday we'll have robots do everything for us. We're not quite there yet.
It seems like MySQL 5.7 will start to have better GIS support. Though that is still a development release at this point. Hopefully if Amazon tries to maintain compatibility, native GIS support may eventually arrive.

BTW, since there's no way to search for "google+" on Algolia HN search, I made the same dupe mistake this morning (sigh).
I think that this is definitely contentious given that many of the best bands that formed that year didn't peak until much later. Death's best album, for example, is probably either Leprosy or Human, which are both from several years later.

Also, Stryper were formed that year, which is an automatic black mark for me (no offence to Stryper fans intended, it's definitely a matter of personal taste...). And why is Bon Jovi in a list of heavy metal?

From the list of albums released, I see a lot of cheese and a few classic albums, with some degree of overlap. It's not very impressive to me personally. Electric Wizard and Nile won't even form for another decade, Immolation won't start putting out their most important work until '96, Emperor until '91-ish. Actually, I find 1991 or 1993 way more convincing personally:

https://en.wikipedia.org/wiki/1991_in_heavy_metal_music
https://en.wikipedia.org/wiki/1993_in_heavy_metal_music

I still reject the idea that metal has peaked yet.

Are you maybe a NWOBHM/Speed metal fan? I could definitely agree with that style peaking in the early-mid '80s.
