I replied to you regarding this in another thread.

In short, its #2. It's to do with volume. By producing a large volume of an unprofitable product you would usually lose more money than someone producing a small volume of an unprofitable product. However, because of the subsidies, this has been reversed, and you now make more money than someone creating a smaller volume. This is exactly how these large farms have been established (they were incorporated to take advantage of these very subsidies), and they have used the large "profits" to further grow. The margins have further reduced, but they are still "profitable" because of the volume.
Correct.

There is risk most any human activity. Your prudent thing would result in suspending any beneficial activity with any possible risk. The a prudent thing would be to err on the side of still receiving the benefits of 737 air travel.
> that airline has a bad safety record

Could you substantiate the above claim ? Whatever I have read indicates Ethiopian has a very good safety record.

e.g. The airline has a safety rating of six stars out of a possible seven on respected aviation site AirlineRating.com. Source: https://thepointsguy.com/news/despite-recent-crash-ethiopian...

U.S. Lawmakers Call to Ground the Boeing 737 Max 8. FAA Says 'No' for Now
It isn't just the FAA and Boeing.

Where I work many of us have a "common type rating" between the A330 and A350 (-900 and -1000). While I commend Airbus for making them similar they are in no way common enough to justify the minuscule training course.

Flying the A350 you get lots of brilliant features like brake-to-vacate, auto wing leveling during a crosswind landing (when you de-crab), differential flap setting in the cruise for CP control and better fuel efficiency. And so on.
However, coming back to the 330 after lots of 350 flying it's very easy to forget just what you have and don't have.

Both have very different cockpit layouts. Even something simple like cockpit lighting is totally different. They have significantly different limitations, speeds and procedures for dealing with abnormal situations.

Additionally, the A350 still has a fair share of teething problems. The list of Temporary Abnormal Behaviors is quite long and hasn't shortened much in the last couple of years.

Throw some fatigue into the mix and it's not much fun. My company's error rates have increased on the "common fleet" by almost triple.

Yet our regulator thinks it's all good.
The Wikipedia article on formulaic language (pointed out by another commenter, thank you!) is helpful here.

"There is strong empirical evidence that speakers use formulaic language in similar ways across languages and that formulaic language plays a fundamental role in the structuring of spontaneous speech, as they are used to achieve a better synchronization between interlocutors by announcing upcoming topic changes, delays related to planning load or preparedness problems, as well as speaker's intentions to take/give the floor or to revise/abandon an expression he/she had already presented."

https://en.wikipedia.org/wiki/Formulaic_language (citing a 2007 study)

In conversation, formulaic language can help you seem more relatable to other people. Think of Indiana Jones, the beloved hero who often used formulaic language to express himself, as compared with the villains, who barely varied from perfectly formed sentences. You can see the same pattern in countless stories because the writers target an audience that feels more comfortable with people who talk that way.

Does the FAA set the rules for Indonesia? Did the FAA tell Lion Air not to repair the broken airspeed indicator that crashed plane experienced during the flight before the crash? Also, did the FAA tell the pilot to turn off the anti-stall system in the Lion Air plane? Because that’s what happened, a pilot turned off that system due to the unrepaired airspeed indicator. In the US, no airline would have allowed that plane to fly, but Indonesia’s airlines are operated like they’re flying bush planes and not technologically sophisticated airliners. People are dead, a lot of them, because of a history of third-world style seat-of-the-pants duct-tape piloting and maintenance. Look at Lion Air’s safety record and compare it with Southwest Airlines. Flying similar planes, but vastly different outcomes. The FAA must be doing something right. Lion Air wasn’t a failure of the airplane, but a failure of the airline. This isn’t the first time Lion Air crashed a 737 either. Considering Southwest Airlines has flown over 40 years with only a single air mishap fatality, it’s pretty fair to say that Lion Air is horrific by comparison, considering their fatal crash record over just the past 10 years.

If we want to start complaining about the FAA, considering more people have died in Indonesian and Malaysian air crashes in the past 10 years than have died in American crashes despite the US flying several orders of magnitude more flights. Lion Air wasn’t even allowed into the E.U. until 2016 because of safety. The FAA and NTSB are among the best agencies in the world when it comes to aviation safety and the data supports it. If anyone should be held accountable for the Ethiopian Air crash, the airline itself should be at the top of the list: the copilot only had 200 total hours! That FAA you are complaining about requires 1500 hours of experience to sit in the right seat. But apparently in Ethiopia, a 200 hour student pilot is good enough to fly right seat when over a hundred lives are at risk.

> - Lion and Ethiopian Air are near the bottom when it comes to maintenance and follow up with Boeing

Another commenter mentioned that Ethiopian Airline is considered Category 1 by the FAA, and is a member of the Star Alliance. Surely that indicates a decent track record?

I'm not saying it _is_ the plane, but as the EASA Emergency Airworthiness Directive points out, while a connection between the two incidents cannot be established, neither can one be ruled out. And for that reason, they are grounding the planes as a prudent temporary measure till we know more.
> If it turns out this was not Boeing's fault, a lot of people are going to have to eat their words, and millions of dollars will have been wasted for nothing.

And if it turns out there is a fault, hundreds of lives can be saved. What losing side of the wager do you want to be on?
Rather important is that it was in fact considered to have substantially different enough behavior to warrant a required type rating for pilots, obviated due to the software abstraction provided by MCAS. However, this abstraction is effectively disabled when setting stabilizer trim to cutoff which is one of the later steps in the normal troubleshooting sequence. OK? So the airplane is in an emergency situation, with a flight characteristic normalizing software routine disabled, thereby making it possible for the airplane to exhibit the very behavior that pilots were never informed of, never trained for, and not required to have a type rating for, that MCAS existed for in the first place.

I think that's quite a lot more relevant than airline safety records. Ethiopian Airlines has a good recent safety record anyway. And the outcry, upon MCAS being publicly revealed, among the U.S. pilot community I also think demonstrates important relative concern.

And, quite a concerning story about U.S. 737 MAX pilots using the anonymous aviation safety reporting system to communicate their concerns, whether instead of or because of the normal channels for doing so.

> The sudden rush to judgment on this case is unjustified by the evidence.

It might not be justified by a theoretical formal proof. It irks me that a lot of the HN population seems to always want to reason using formal proofs like if it was a silver bullet.

In this situation, bayesian inference is appropriate, and tells us that grounding planes is highly justified. This succession of two relatively similar events in a new plane is enough to raise the probability of "this aircraft model has a problem" a lot, and definitely enough to justify grounding them.

Also, the risk / benefit ratio is not symmetric, what is better:

- Ground them for nothing and lose money

- Not ground them to save money, and see a third crash happen, killing 150 again

If you take into account those two effects, it's clear that grounding the planes is a sane option.

Finally ask yourself: would you board this plane today if you had a ticket? What would you think when there is turbulence after takeoff and the plane suddenly pitches down for a second? What color would your pants be?

Quite. That doesn’t pass the sniff test.

If it turns out this is Boeing’s fault, for the reasons suspected, and the FAA have staked their reputation on it - I fear for the future of airline safety.
The (magnet) elementary school I attended used a lottery to select among the top X% of applicants. It did not "tarnish the pedigree of the school" or anything like that.

There is already a lottery to select which students among the thousands who apply will be offered admission. It's just not uniformly random.

They had a 200 hour pilot flying in the right seat of the crashed airplane. Star Alliance or not, who in the hell defends a low-time student pilot flying right seat in an airliner? In the US, that would be illegal as a first officer has a 1500 hour requirement along with significant multi-engine turbine training. That copilot wouldn’t even have enough hours for a commercial certificate, let alone ATP.

Don't you think these two statements are at odds? If there is no difference in practice then why does unfamiliarity kill?

"In theory there is no difference between theory and practice, but in practice it is different".
I find the opposite is true. I can't count the number of times I've accidentally closed a window or backed out of a page using a modal where the semantics were unclear or the comically tiny 'x' was hidden below mobile-Chrome's sliding address bar on a page that was too short to scroll.
>This is a STEM-oriented view. In a lot of fields the primary cost of research is faculty time, and it is often paid by tuition.

While I don't doubt there are colleges out there that primarily function of tuition, I'm fairly confident that the schools that the GP was talking about which take in millions of donations, are not funded by tuition - STEM or not. Endowments are practically tax-free hedgefunds. There are several liberal arts colleges in boston with billion+ endowments - where the return alone on the endowment rivals the total revenue from students (assuming they were all paying the full 50k, which they likely aren't).
>Ethiopian Air are near the bottom

This is ignorance, Ethiopian have been flying for 70 years and have an excellent safety record on par with most western airlines.
Sure, then let's fly other unsafe planes types as well to save money, and hand the benefits to the poor!

Except, in which universe do airlines hands out their revenue to the poor ?

FWIW, I don't believe Google was pushing a patent encumbered web, or H.264. Their VP8/VP9,VP10 funding speaks for itself.

No one wants a monopoly in the browser space, and it seems like Mozilla has some other bone to pick with Google. As stated before, developers and web users come before Mozilla's philosophy, and many of the objections to Google's proposals don't seem to further that mission. Maybe some of it is in Mozilla's self preservation interests, I don't really know. But a lot of Google outrage seems feigned, and contrary to developer and user interest.

If you haven't noticed, most devs here haven't raised any technical objections, instead seem pleased with the offering, that's a hint in itself
PGP isn't demanded, but a different kind of signature is increasingly demanded: DKIM. Only a minority uses it to reject mail on its own (although I guess that minority is bigger than the number of PGP users), it's widely used as part of a scoring system.

Except for, you know, that computer system that throws people into the ground if a probe malfunction, and that the "just short of non existent" training doesn't seem to cover properly.

I don't know how this part works, when a manufacturer says "this plane doesn't require full training but merely a small top up since it's the same as plane X before", I assume the FAA needs to validate this matches reality ?
Nobody is talking about ground the 737 - a very safe plane used thousands of times a day

This is the 737-max, a new plane with very little history, barely used, and had been involved in two crashes with similar circumstances in the last 6 months.

Conceptually it's not hard at all. "When you send an email there is no proof that it came from you. It is easy to fake emails. When you press this button, it will 'digitally sign' the email. Now people can tell that it comes from you."

It's the key exchange that's difficult. However, as the blog rightly points out, having companies sign their emails would be a massive step in the right direction. Every ordinary person uses an email service. If that email service handled the key exchange for those companies the it would be truly wonderful. It doesn't even need to be that difficult given that these companies almost certainly have certificates for their websites.

Then all the service provider has to do is put this nice message when delivering the email: "This email was not signed by the company that it claims to be sent from. Beware." Not in any way difficult for an ordinary person to understand.
It’s easy. The mail teams at Apple, Google and Microsoft are running in maintenance mode and honestly there’s no money in it for them to invest in it.
There is no ‘promise that users will support the maintainer’ and never has been.

Open source was originally about developers sharing code with each other and jointly contributing to it, to make their lives easier. Look at all the original GNU projects, they’re almost entirely developer tools, shared infrastructure and games. The core right of open source is for users to modify the code, because in the GOL no distinction is made between users and developers, they are the same.

The fact that some people have been able to build companies on open source software is essentially a happy coincidence. That outcome wasn’t considered or deliberately provided for in the licences or by the movement. If it hadn’t been possible at all, the movement would have been fine with that.

Now that we have decades and generations growing up with commercialised open source, people are thinking that this was by design and something is wrong if open source isn’t commercialisable in this way or that. No. Nothing is wrong. Commercialisation is occasionally an incidental side effect. It is not the point.

I thought by "pay-to-play" you were going to point out the other opportunities to use money to perpetuate social stratification. It's not just "endow-a-chair" levels of wealth that improve the odds, it's also:

- Live in a rich metro area? Now you have access to things like internships & research opportunities not available in low-SES areas.

- Parents have high-status jobs? Now you have access to experiences offered by your parents' friends and colleagues, for example, to do research at a local university lab if your parents are professors.

- Don't have to work summers? Now you can take a "finding yourself" trip or volunteer to build housing in Africa or whatever it is these days.

It's much easier to engage in extracurriculars that show how great/community-oriented/socially-conscious/talented at music/sports/research/debate/whatever you are when you grow up in an upper- or upper-middle-class family in a wealthy-enough neighborhood to parents with strong social and professional networks.

This is the social stratification that's perpetuated by elite school admissions processes, it's the top-20%, not the top-1%. It's not any less dangerous, and in fact may be more so -- and the income numbers alone don't tell the full story.

Lastly -- those wealthy enough to endow a chair don't need Harvard to perpetuate social stratification, they will simply inherit enough wealth to do so!
I would prefer not to contribute to Chrome's increasing dominance, but I feel like I don't get much of a choice. I want to choose a browser on its merits. For me that is currently Vivaldi. Where is the Firefox-based Vivaldi equivalent?

Mozilla does not really seem to be addressing the fact that they provide one browser - Firefox - that is competing against an increasing array of Chrome-based browsers, all providing different user experiences. Why has no one built an interesting browser on top of Firefox?

It stands to reason that Chrome cannot be all things to all people. Neither can Firefox. The difference is that alternative browsers are increasingly Chrome-based, with the single exception of Firefox. Unless Mozilla (or someone else) can reverse this trend, I think this battle is lost.
And if it turns out to be a fault in the max’s design, operation, or training procedures?
