Southwest has more 737max than anyone else. However they have outfitted it with an optional avionics package that includes a HUD, an additional AoA sensor and indicator in the HUD and PFD, and an "AoA disagree" indicator light. (https://theaircurrent.com/aviation-safety/southwest-airlines...)

They also train their pilots using a 737max specific curriculum.
There are plenty of proper ways to do things. Ex: Trump could have said that the acting director of the FAA has news about the MAX 8.
You keep posting this Reddit comment in every single one of these threads. Maybe lay off for a bit?
Official rulings aren't in yet, so this is all wild speculation, but the dominant hypothesis appears to be that these new planes are equipped with MCAS ("Maneuvering Characteristics Augmentation System") software that is supposed to account for inherent aerodynamic instability in the design by making it much harder for the pilot to accidentally crash the plane.

Without going into too much detail: there are many tradeoffs in airframe design, but one of them is fuel efficiency vs. inherent stability. Some airframe designs eke out a bit more miles-per-gallon at the cost of having ranges of motion where if the pilot gets the plane into that state, the feedback loops on motion become positive and the plane is likely to tip over, stall out, spin, etc. Boeing's Max-8 design makes this tradeoff, and the MCAS system is supposed to help compensate for this design by forcing the pilot to nose the plane down (to improve airflow over the wings and generate more lift) if the plane is pitched too high.

Problem might be that MCAS can malfunction and think the plane is pitching up when it's not, and if the pilot can't figure out how to disable it, they get very confusing signals--- they're pulling back on the stick to get the plane to climb, but MCAS is pushing the stick forward to avoid an expected stall that a malfunctioning sensor is telling it will happen. End result: pilot and the computer fight each other while the very important business of "keeping the plane in the air" isn't done and the plane crashes.
The static mirror https://epitactic.gitlab.io/cloudbrowser/ is just a static HTML page + image hosted on GitLab Pages, so it should always be up, but the links there go back to the online demo which was down.

Unfortunately, I'm only hosting the demo on a quad-core 6GB VPS, which frequently runs out of memory. There is a known issue (https://gitlab.com/epitactic/cloudbrowser/issues/2) where old Chrome processes are not cleaned up for some reason. I've restarted the VPS, should be available again for now, for at least a while.

> Linux and Docker! Yes, you’ll have the same deterministic and secure result

Nope, not at all. Dockerfiles are not deterministic. Most of the ways I see Dockerfiles written are highly non-deterministic. Docker also requires root access and to some degree exposes that root access to any user with Docker access on a host.

The "stacked filesystem" model also allows far less flexibility than Nix does when it comes to composing a system out of different components. The fundamental problem is the inability to combine features of Docker images with different bases. Compare this with OO languages lacking multiple inheritance.

However, in my eyes, the biggest sin of Docker is the conflation of the problem of software dependency management with isolation & security policy. The two are fundamentally different things, causing developers pain when doing local development and leading to security-slackening changes that make their way into production. NixOS does not make this mistake.

Last time I was running a project with NixOS I was able to git bisect my entire application & software stack to locate the source of a regression (a package maintainer had changed the location of a file) - what can you do?
The most common practice I've seen is to build a configured system on another machine and ship it to EC2 via `nix copy` or `nix-copy-closure` and then activate it by running `switch-to-configuration`.

The market has a solution for that: competition. Any CRM that fails to distinguish itself will eventually fade out of existence. Those individuals make a choice to work where they are, doing what they do. Let's not pretend they have no agency. And if customers find the CRM product valuable to them, then those thousands of individuals are performing a valuable service for the world. Saving time, improving efficiency, these are all noble things to strive for. It's not a small thing. There's no such thing as a bullshit job.

In Germany, they actually demanded an "Internet eraser" (https://www.heise.de/newsticker/meldung/Digitaler-Radiergumm...) [so ridiculous I don't think anyone ever attempted to translate] so content, mostly images, would somehow 'automatically expire'. Never worked, images could be screenshotted, etc. etc. Said this was "highest standards made in Germany". Never made sense, never took off.

I think prior to painting in any style, it is useful to learn how to draw. I found this book recently which I think is really excellent. As you progress through the exercises, the instructor has you work in different media, including paints (but in order to learn how to express a 3d object on 2d material).

The Natural Way to Draw by Nicolaides. It might be found at a library but here is a link to amazon (I don't get any credits for this just for ease of searching)

https://www.amazon.com/Natural-Way-Draw-KIMON-NICOLAIDES/dp/...

Otherwise if you're more experimental maybe just study your favorite impressionists and try to copy their style on your own subjects until you find your own way to do it. I personally am into being methodical but this approach (starting realistically) just takes longer.
“Outage, what outage?” Is a sort of laughable response but all too common with tons of providers.

> He told them what to do

That is...unclear, at best. The only account of the decision making I've seen in any news source that comes from anyone involved (e.g., excluding CNBCs unsourced claim of an "executive order") is Boeing's claim that they recommended the action "in an abundance of caution" to the FAA which acted on it. (EDIT: Actually, the FAA has just tweeted that they made the decision, based on evolving evidence from the investigations, so that's another narrative.)

Of course, the White House can assume the privilege of announcing any decision from anywhere in the executive branch, and the President announcing it as an "emergency order" that "we" are issuing is factually correct where "we" refers to the Executive Branch.

Hi, I'm Jonghyuk, one of the co-founders. One point I would like to add is that a 90% accurate AI model may not be very useful for an application, but with the right data pipeline and well-designed system, we can extract quite a bit of boost out of it for data annotation.
There might not be much in the way of proof, but it's an interesting story. Tesla calls police, says Tripp has threatened to shoot up place. Police investigate, say "no threat". Tesla says, "Hey, hold a press conference about it anyway!", sheriff declines, says "Can I speak to the person who says he called in a threat?". Tesla declines to make any witnesses available (which, huh? How can a company 'decline' to make a witness available for a criminal threat), but sends out their own press release anyway.

He's talked rocket design specifics on many occasions and "built his own rocket" according to Vector Launch CEO Jim Cantrell [1]:

>He borrowed all of my college texts on rocket propulsion when we first started working together in 2001. We also hired as many of my colleagues in the rocket and spacecraft business that were willing to consult with him. ... I found out later that he was talking to a bunch of other people about rocket designs and collaborating on some spreadsheet level systems designs for launchers. Once our dealings with the Russians fell apart, he decided to build his own rocket and this was the genesis of SpaceX.

Additional info from Jim from a follow-up interview[2]:

>Cantrell ... loaned him some textbooks to study. The books were "Rocket Propulsion Elements," "Aerothermodynamics of Gas Turbine and Rocket Propulsion," "Fundamentals of Astrodynamics," and the "International Reference Guide to Space Launch Systems." He would quote passages verbatim from these books. He became very conversant in the material. ... Musk would absorb this information and then hold his own in conversations — and he didn't hold back.

Additionally, Ashlee Vance's biography [3] describes his day-to-day as "quite involved with rocket design" at SpaceX and goes into a lot of detail about spending time on the floor assisting SpaceX scientists with their designs.

Obviously any single person at a company the size of SpaceX doesn't individually design and build a rocket by themselves, but it's generally agreed upon that Elon is knowledgeable in rocket science and contributes many ideas to the designs.

This webcomic speaks directly to this issue.

We didn't have "applications" back then, we had "programs".
Probably not completely true. An airfoil stalls when the critical angle of attack is exceeded. For most airfoils, this sits at around 17°. For all commercial aircrafts (I think 727 onwards) there is a mechanism called stick pusher that will not allow an airfoil to go over critical AoA. I am not sure if this has been overridden somwhere in the 737 Max 8 though.
Theories I've read so far:

1. Ineptitude
2. Corruption/Greed
3. US planes don't have the same issues that is suspected to be the root cause of other crashes.
Trust is the currency of politics.

Trump is a documented pathological liar, far beyond anything US politics has seen in multiple generations of Presidents. It isn't the "truth massaging" that Americans expect all politicians to engage in---it's pathological lying about trivial issues as well as large.

He has burned trust at so many points in his life---before his election and during his Presidency---that if there was a report he saved 50 babies from a burning house, the very reasonable first instinct of many non-eye-witnesses would be to question the source of the report and verify there was a housefire at all.
There is a window now when players can argue that the regulation text isn't clear (it is). Let's hope regulators pick a few high-profile targets that are in violations and hit them with massive fines.
The key part of the phrase is "unless Tesla starts cooperating". I'm sure Tesla will actually cooperate if there is an actual danger as opposed to another attempt to get the Sheriff's office to lie for them. The Sheriff is not doing anything wrong, and Tesla should have learned the whole cry wolf thing long ago.
Propose solutions.
Makes sense, thanks for the explanation.

Basically everything about this plane boils down to "it should require more training but it didn't"
The ever-impartial Wikileaks? Sure, let's jump right on that...
Internal documents can contain confidential business information that is of use to competitors etc. which it may be illegal or a violation of an NDA for you to expropriate and publish. Then it becomes a public exhibit of everyone attacking each other and defending themselves instead of people working to actually solve the problem.

Moreover, "a company" doesn't do stuff, its employees do. If you're the employee, the first person whose job it is to keep the company from doing dumb stuff is you. And there is a process for that. If you're the one responsible for it, you fix it. If you're not, you alert the person who is, then their boss if that doesn't work and on up the chain to the government until it gets fixed. If that process works then the problem gets solved without there being anything to create a media storm over, and if that process would have worked but you decided to skip it then you're creating a media storm over nothing.
I'm not that versed in Haskell myself, but is this really the case? I would think that expectations for low level optimization and general code are different.

Though, I suppose you could then say that if the rules are different for low level optimization, they may as well have imported an external library written in Rust.

We're almost living inside the black mirror world.
It’s also that the engine nacelles themselves begin to produce lift (and a consequent pitch-up moment) at high AoA.
My favorite painting is Van Gogh's wheat field with crows. Not that I understood why for a long time. I finally realized that when I look at it, I feel like I am standing in his shoes, looking at the field and understand just a bit what it was like to be him at that moment.

There are lots of ways to learn to paint, starting with paint by numbers, taking classes, reading books, but those are not the important parts and they often get in the way. The essential thing is finding a way to get the painting to tell someone about how you, emphasis on you, experience something.

The good news is that just making the attempt will make you a better coder!
If these planes are being crashed multiple times per year, even if by less experienced operators, then Boeing is still at fault for designing an unsafe airplane. Other planes do not have these issues.
It's time for app developers to unionize. Collective action is the only way to level the playing field.
And a lack of modification specific training, which some pilots have already been pretty vocal about.
>Surely there has to be some aesthetic guidance along the way?

It's generally better to run the feedback through the same unconscious mental pathways you use to do the activity, rather than the verbal storytelling loop that can think thoughts like "I don't like how I did this". Use the parts of the brain that are good at painting, not the parts that are good about telling stories about your painting.

I highly recommend reading "The Inner Game of Tennis" to get a much better sense of this distinction. It's broadly applicable to all sorts of skill acquisition and improvement. The best way to learn how to do something is to quietly and non-judgmentally watch yourself doing it. Your brain is really good at figuring that all out once you've started.

> Either way, it doesn’t justify calling in a fake bomb threat.

Police investigated (it was a shooting incident, not a bomb threat), found no credible basis, asked to interview a witness, who Tesla declined to make available.

Why so sure he made a threat?
It's hard to describe, but here goes.

The Center of thrust is offset down and somewhat in front of the CG, this means high thrust imparts a pitch up moment. Small, but present.

The bigger problem is the nacelles shape though, they create body lift at high AoA; imagine a vacuum bubble trying to suck the wing/nacelle backwards forming in the airstream, "pulling" them back.

Combine both of these characteristics, and you have an airframe demonstrating near stall positive pitch instability. I.e. you get a moment that if left uncountered will reinforce itself until the plane ends up stalling; behavior completely unprecedented in the airframe.

So in order to "counter" this behavior an automated system was introduced which supposedly restored the pilot relative flight characteristics in line with the old airframe's specs.

I'm probably oversimplifying, but it's the closest I can get to a visualization that makes some sense.

Drawing provides a way of representing 3D objects into 2D space; it's not what drawing is.
IT wasn't inevitable. There's nothing that's found to be unsafe about the aircraft. If anything it shows that airlines in other countries don't train their pilots properly. MCAS can be disabled by an easily visible switch directly in the cockpit and you can override it with manual trim control as well. The Lion aircraft that crashed before was having MCAS problems _FOUR_ flights repeatedly before the one that crashed. Third world aircraft maintenance combined with poor pilot training and non-idiot proof software made these disasters happen. It's not something that would happen in the US or any other first world country.

I disagree with GP, but this is basically how firings are handled at high levels.

It's very rare for a POTUS or a corporate CEO to actually fire a direct report. Instead, they say "you have X days to resign before I fire you" via a side channel, and most of the time the report opts for the resignation.

(funny thing is, at the first company I worked for, the CEO did this to the VP of Engineering... and the VP assumed he was bluffing, waited out the whole 30-day period he was given without resigning, and then got walked out of the building one morning in front of everyone who was there that early... and the guy who was in charge of walking him out was one of the people who was promoted to replace him)
i have been thinking more about this and i think you are right. on GOG i am (depending on rightsholdet) able to add games to my library that I own on steam. if this was the norm, enforced through consumer rights, it would allow users the ability to purchase licenses through a store of their choice.
It's because of MacOS's dark mode is a little more established the Win10's. It makes sense to release the feature there first.
The decision to close most of the stores is (mostly) reversed, but the price drop to $35k for the Model 3 is not reversed.

“Based on new information...”

What new information??? Or maybe “the taste of egg on our face?”
I work for a smaller but comparably large platform. "If everything is down check the DB" is at the top of one of our internal monitoring websites in red.

Screw ups related to data loss are rare (I've been here years and haven't seen one with the DBs that the stuff I work with uses) but failures at this scale tend to cascade a little ways and it takes time to dig out of the hole. They probably have the problem solved but they have to spend a bunch of time synchronizing things and verifying the fix before they press the big red "go live" button.
It’s almost literally true that he owned said company at a single point in time. His airline had a trajectory not unlike a 737-m.
