When you spin a combination of stuff that is "loose enough" at sufficient speeds, the centrifugal force acts on the constituent masses differently. As a result similar masses coalesce.

This is the same principle used to separate and concentrate (enrich) all kinds of stuff in centrifuges.

I know them being the richest couple in the world with a publicly traded company makes this a special case, but I can't help feeling a little strange seeing the details of one's personal affairs broadcast in such an enterprise-y, "update to the people" manner. It feels just as fake as any other "letter from the CEO" I used to read at a fortune 50.
Hi! You typically want to breath out through your noise, then inhale through the mouth when you go for air.

Another tip that comes immediately to mind is try using a swimmer’s snorkel. At first, it’ll be really difficult to keep from water going into your nose but after a few practices, your nose and it’s canals will block out water as a reflex, enabling you to breath through your mouth the entire swim. Hope this helps and sorry for English!
> I am not a Chinese dissident....So my personal consequences of Chinese surveillance are rather limited.

I would recommend that you think of yourself as a dissident, including as a foreign dissident, even if you aren't actually one. I think that attitude can be a great source of moral guidance and perspective.

> You can't both require MCAS and be okay with disabling it at the most critical portion of a flight where the system is needed most.

If MCAS activates when it isn't supposed to, which is what happened here, disabling it is what you want to do--to stop it from doing an incorrect thing. The plane was not in a situation where MCAS was needed; it was perfectly flyable without MCAS in the flight regime it was in.

The problem is that, if you disable MCAS (which requires disabling the entire electric stability trim system) without first using the electric trim system to get back to something close to neutral trim, you will be stuck with a lot of nose down trim that you can't remove fast enough with the manual trim wheel. It looks like that's the situation this flight got into.

But if you first use the electrim trim system to get back to something close to neutral trim, and then, before MCAS has a change to mess it up again, disable the entire electric stability trim system, you're ok. How do we know? Because that's what the first Lion Air flight (the one the day before the one the crashed) did, because an off duty pilot that was riding in the jump seat figured out what was happening and how to deal with it and told the pilots what to do.

I would guess that the node down attitude quickly put them over VFE, so even it they could extend the flaps (I don't know if the flight system would prevent that or not) they would at least second guess doing so and continue other avenues of troubleshooting.
It's not that simple. If the AoA is too high that can cause a stall and crash, too.
> I don't think many doctors recommend this for the general public

> A CT scan comes with a strikingly high radiation dose

Another challenge is that they probably wouldn't give you a baseline scan from the bottom of your toes to the tip of your head. Abdomen/thorax and/or head/neck, probably. So you can't get the whole skeleton. A planar "scout" scan of two dimensions is normal examination procedure prior to the diagnostic scan. Those can often run a long portion of the body. You might be able to project something from that.

Aside: The Sievert (SI unit referenced in the XKCD comic) is a really interesting (IMO) unit. Instead of measuring the radiation in normal "amount of radiation" style, it measures the "equivalent dose" intended to help understand the ultimate biological impact of the radiation. The radiation emitted might be measured in Joules and the radiation absorbed might be measured in Gray (Joules/kg), but Sievert can be weighted by the tissue that absorbed the radiation. Your gonads or your head would have a greater weight than your ankle (or so I figure). This, I would guess, gives radiologists a much better way to consider the net impact of a diagnostic procedure in order to weigh against the overall diagnosis & prognosis.

Also, another aside: dose has become a more competitive feature for CT manufacturers in the last decade or so and several offer features to measurably reduce the dose.

Well it's also a sport in it's infancy, not a more-than-a-century-old sport that's literally called "America's Pastime". Maybe when it's older than a couple of decades, the social factor of the sport will be more present. I was into eSports as a teenager, but it was very, very niche at the time, as you say. Nowadays, gaming is so commonplace with teens that a streamer like Ninja is able to reach a level of pop stardom.

Reminds me of my first job processing radar data on a Masscomp mini-computer. The full processing was a bunch of simple c programs all unix piped together into a processing chain. Simple and elegant.

We appeared to have a persistent bug though, processing left running overnight always seemed to crash. So after a couple of nights I stayed in the lab to try and see what the cause was. At 7:30pm the lab door opened and in walked the cleaner who reached down and unplugged the computer so that he could plug in the vacuum cleaner. Problem solved.

The title is misleading. The website mentions all these -

We discuss the limitations and implications of this work in detail in the paper, however, it is important to re-state here that these findings:

1) Cannot be directly used to infer safety as a much larger dataset would be required for crash-based statistical analysis of risk,

2) May not be generalizable to a population of drivers nor Autopilot versions outside our dataset,

3) Do not include challenging scenarios that did not lead to Autopilot disengagement,

4) Are based on human-annotation of critical signals,

5) Do not imply that driver attention management systems are not potentially highly beneficial additions to the functional vigilance framework for the purpose of encouraging the driver to remain appropriately attentive to the road.
> Why does having less cars create less usable land?

Not "usable-as-in-present", but "usable-as-in-available".

Having less cars drives up the value of land, making land more expensive for everyone, and making that land less usable for any one person specifically.
I'd dare to say that many groups/products at Google aren't even operating at Google scale. I'd also dare to say that some Google products operating at Google scale can be a bad thing (i.e. unprofitable). The latter statement, or both statements, might be supported by the number of products they kill off.
Tangently on that matter recently I posted a question on HN and would love to read your comments.

For store-bought kvass, it all depends on the brand. The cheaper ones are exactly as you've described, but you can get the real thing, too.

I wouldn't compare it with Coke taste-wise though. I mean, it's basically a fermented drink with rye bread as a base. Aside from the color and the bubbles, it's not really similar.

You can look at it the other way around: GDPR can be a barrier to entry in the European market, therefore making EU compagnies more resistant to outside competitors, which increases their valuation.

As a foreign company, if you want to enter the European market you can either comply with GDPR (which honestly is not that hard despite all the FUD), or take a stake in an existing EU company, provided you let it continue operating as it currently does or at least in a GDPR-compliant way. Buying a EU company to siphon off its customer data (even if it’s just to merge with your own platform) is a big no-no, unless you yourself are GDPR-compliant.
Sub-competitive freediver here, so I thought I’d comment a bit on how my sport stresses the lungs and how the body adapts to that stress.

First a comment about the debates over how often you should breathe...almost certainly, those who advise breathing less often are right. People who haven’t trained in apnea and haven’t learned to tolerate high levels of CO2 in the blood always assume the urge to breathe has to do with not getting enough oxygen. But in those sessions where you were “audibly gasping for air,” you were mainly satisfying your urge to expel the CO2 that had built up in your body and, after 1-2 breaths, your oxygen levels were mostly back to a point where you could’ve started breathing normally again. Even after 5 minute breath holds, I try to only take 2-3 recovery breaths before I return to my normal breathing cadence. Breathing less often, since it sounds like breathing slows you down to some extent, should just be a matter of dealing with the discomfort of a higher build-up of CO2. If you were to specifically train for CO2 tolerance, that wouldn’t be that big of a deal. I’m actually somewhat surprised that apnea training hasn’t become an important part of training to be a competitive swimmer.

Secondly, there have been a few studies that have looked at the physiological changes that happen to extreme breath hold athletes, so those may be of interest to swimmers because they may experience some of the same changes. One study showed increased basal metabolic rate and ability for the blood to hold oxygen. It seems like the training makes the body want to store more oxygen and use less of it to convert stored energy reserves. It wouldn’t surprise me if swimmers saw some degree of those changes as well.

Lastly, one important difference between freediving and swimming is the effect on the heart. Freedivers are specifically focused on not putting stress on the heart. We try to relax and lower our heart rate to use oxygen as slowly as possible. Even in dynamic disciplines, the focus is on slow, relaxed strokes, even if that results in more time spent underwater. A freediver swimming 200m on a single breath (whether horizontally or vertically) will likely have fewer heartbeats during that swim than that 50m swimmer you described. But what’s interesting about that is that freedivers still experience some of the beneficial changes to the heart that swimmers and runners do. For instance, when I first took up the sport, my resting heart rate dropped to about the level mentioned in the article (below 60 bpm) and my blood pressure dropped to the point where my doctor was somewhat worried (90/56 at one point). I think there’s something to what you mentioned about putting pressure on the lungs. The heart and lungs are really one interconnected system and you can affect one by affecting the other.

Maybe Hadoop isn't necessary for everyone who needs it. They'll learn. And if they don't, more job security for you.

Otoh there are some crazy advantages of running certain "large scale" softwares. Not everyone needs the "scale" Kubernetes offers, but managing tasks declaratively as containers that get scheduled on boxes in a hermetic fashion? Or maybe continuous delivery - not everyone needs CD, but it certainly offers many advantages to those who do it.

Most people could probably live off of shell scripts running under Cron on a box with CGI scripts written in Perl without any issues, that does Not imply there are no advantages to new technology because not everything is about scale and fault tolerance.

Yup, experiencing that at work quite a bit. People are currently arguing about big data solutions for a data set of 300Gb or so, growth in the area of 100ish Gb / year. I'm still arguing that this could be an in-memory dataset for postgres, and we wouldn't need that with a good schema.

Or other people are wondering if we could replace all of our relational databases with kafka. While complaining about inconsistent data sets. Well let's talk about advantages of a good relational schema first.

MCAS system is supposed to stop the plane from stalling.

The faulty AoA sensor is causing the plane to think it’s about to stall and therefore MCAS works as designed to prevent the pilot from putting the plane into a stall.

Of course the design is wrong because the plane is actually pointing toward the ground and MCAS thinks it’s pointing to the sky...

I cited a couple of examples in another comment. In any case, I didn't proffer that as just an opinion. It's also a prescription for how you could find tons and tons of evidence. Explicitly look into people who are not "Alt-Right" but who have been labeled that way as a means of quashing their message. This will often follow the pattern of the Boston Rally: Non white people for whom the media is pushing an anti-non-white racism narrative.
Strongly disagree, but depends on the game I guess. Dota 2 players' popularity is often heavily influenced by their personality, even if that personality is largely on display between matches, and even outside of tournaments if they stream. The tournaments (the big ones at least) have a live audience (which is sometimes piped in to the stream via a mic) and commentators who help contextualize the energy of the situation. When they cut to the players in the booths, they can often be seen celebrating and full of energy.

I think the real issue is you watched competitive FIFA, which (to my knowledge) doesn't have a very big community who cares about it deeply.
I am currently going through interviews, here’s my experience.

Give a general overview of your company first and why you need to hire before asking questions.

Don’t ask for a generalist because that just seems like you don’t know what you want to hire.

Be prepared for the meeting. You can tell a lot about an employer on what they say. Are these questions well thought out? Or is he/she just winging it?

Don’t assume candidates don’t have options and would do anything to work with you. You aren’t Elon Musk.

Be punctual.

And most importantly, be polite even if you don’t think that candidate is right for you. I always warn others if I had a bad experience at a company.

> The plane was not in a situation where MCAS was needed;

As far as I can tell, there is no takeoff (pitch up) situation where MCAS is not needed on the MAX 800. It's required for safe operation of the plane, otherwise the nose might pitch up unexpectedly into a stall.

As I said, the system can't both "be required for safe operation of the plane" and "it's safe to disable MCAS while it's malfunctioning during takeoff." You have to pick one.

To your point, when I often see the "shell script" solution it's often missing basic things you'd want like version control or any kind of bread crumb trail (I find myself sshing in and "grep -r" trying to find things). That works if you're cobbling something together, but doesn't scale beyond 1 person.

It's tough to get the correct level because you can ansible > docker > install an rpm or just change the file in place. Both have their place and "hacky" solutions can work just fine for many years.

Programmers often make the fallacy of assuming that only the asymptotic case should be considered (just look at Big-O notation). But when it comes to specialized tools and frameworks, unlike sorting algorithms, many use-cases never break past the scale where the asymptote is the primary thing driving the curve.

With that in mind, it's my experience that every tool or framework has a different window of scale in which it's ideal, which has both lower and upper bounds, and one simply needs to find one's own project along that axis when choosing a technology. Hadoop may be the best solution as N approaches infinity - and we as programmers love thinking in terms of infinity - but it may not start being the best solution until 10x your actual range for N.
I would use Golang and Postgresql. Possibly add the Chi library for routing and may be GORM for ORM (if you don't want to deal with more direct SQL).
Not quite. With a monothlic, it's an overhead to migrate data, because one small mistake will take your application down.

So, in real world, it takes more overhead to manage a monothlic than a microservice architecture.
I can assure the author that those of us solving problems for small companies (in terms of employee count, not revenue or assets under management) do not jump on the typical bandwagons. We tend to be very critical and pragmatic.

I'm not even sure it is engineers at bigger companies who choose to jump on these bandwagons. I suspect it is often wannabe-technical managers who read that MegacorpX is using tech Y that sells the idea to upper management, along with some unfounded beneficial promises, that causes some of the trends we see.
