Aviation regulator outlines fixes that will get the 737 MAX flying again


Re: $19bn

Have Boeing given up maintaining that they are "making an already safe plane even safer?"

That was a proper tone-deaf new-speak bit of lawyer approved verbiage if ever I've seen one. I haven't yet seen them actually step up and accept any responsibility, presumably because they're still hoping to keep slipping the right envelopes to the right officials and avoid any legal responsibility (remember Trump's comments about needing Einstein to fly planes... whatever that was meant to mean?)


Re: Pilot training

> That still seems the big question to me. If MCAS can be safely made so much less powerful now, how come Boeing felt they had to beef it up so much in the original test flying program? Because they've still go to fix the problem of the plane climbing due to the aerofoil effects of the bigger engines.

I read that the original design, and safety assessments, were based on an "open loop" design, where MCAS would make a single correction, but that it was implemented as "closed loop", so the system would continually poll the AOA sensor and apply further corrections every few seconds. In an "open loop" system with a failed sensor, the annoyance of a single unexpected downward trim is easily correctable. So the failure was probably classed as "minor", and a single sensor input was allowed. In a "closed loop" system, the plane will continually over-rule the pilots until it hits the ground. Clearly in "catastrophic" territory, as demonstrated by Lion and Ethiopian.

Classifying it as one in the safety assessment, but then erroneously implementing it as the other, is what should land people in jail for several hundred counts of manslaughter (never going to happen though - there was good profit to be made, after all). It's also a text-book example of why self-certification is a corrupt disaster. The true American way.

On the positive side for Boeing, fixing it is as "simple" as implementing it the way it was originally designed. Plus a few other tweaks to improve it, since even the way it was originally designed was a bit crappy, and everyone is now looking (only using one sensor, when two were available).

Isn't that the exact crux of Linus's argument? That you should get a better editor, which can handle this?

Re: By the time it's ingrained and encoded into a deep learning net...

> is it still identifiable private info?

This was my question. To take an example, Bob is gay, and has HIV. That's pretty sensitive information.

However, the relevant trained healthcare model will simply weigh the sexuality as a factor against HIV infection. In simplistic terms, the inclusion of Bob's data may push the model's link between those two facts from 20.1 to 20.2. Bob's statistics affect the model's behaviour slightly, but there is no way you could ask the model if Bob is gay - it simply doesn't know or care.

Obviously if the training dataset is retained, that's a completely different story - but I can't see how personally identifiable information could be gleaned about a single subject from a true "black box" model.

Boeing... Boeing... Gone: Canada, America finally ground 737 Max jets as they await anti-death-crash software patches


Re: Negligent certification

This style of response upsets me.

Basically what you are saying is that, in the event of this system failing and trying to nose-dive the aircraft into the ground and kill everyone on board, if nothing else is going on and the cockpit is quiet, there is a procedure to handle the situation.

Now assume you are climbing towards mountains, and your airspeed indicators are bollocksed. You think you are going too fast, so you withdraw the flaps. Your angle of attack rapidly increases, then the stick-shaker activates, there are voices shouting "DON'T SINK! DON'T SINK!", "TERRAIN! TERRAIN! TERRAIN!", "STALL! STALL! STALL!" or similar. The noise of the stall warning horn is blaring out, the yolk is shaking aggressively. Meanwhile the nose of the plane keeps being forced down. Your airspeed is increasing, but you don't know how fast you're going. You disable auto-trim, and there's a temporary lapse where you get the nose back up, bu all the stall warnings continue, so your reflex is not to pull up hard. The nose drops again. You are pulling back on the stick with around 50kg of force, which should also disable all auto-trim and autopilot (as it did on previous 737s) but by that point you are only 1000ft above ground level, your instruments are still reading nonsense, you have no fucking clue why the plane is nosediving and you can't pull the stick back any harder. There is a quiet clickity click noise from the trim wheel, which you already disabled but for some god-forsaken reason it's going again. You're in a nose-dive, 40 degrees down, 500ft above the rapidly approaching mountains.

That all happens in about 2 minutes, in the case of Ethiopia.

Yes, it might be possible to (temporarily) disable the system. No doubt an exceptional crew might handle the situation better. But you know what? Blaming the pilots here is not how you prevent this shitstorm happening again.

Wind tunnel turbulence

I knew a guy who had a student doing some all-night runs in a laminar flow wind-tunnel.

The tests would start in the evening and run smoothly for a few hours, after which (at around 10pm) the flow would unexpectedly transition to turbulent, ruining the rest of the night's results.

The supervisor eventually sat with the student to see what was going on. The tests were set up, the tunnel started, all good. A few hours past, dinner was eaten, and boredom set in. That's when the student turned on the (loud, heavy-rock) stereo system...

Re: How many billions of dollars are being spent chasing this?

> At what age?

About 2.

My 2 year old saw a dear for the first time ever, while we were all looking the other way, and immediately said "goat!"

Which, considering she'd only ever seen goats once, about 3 months before, was a pretty good extrapolation, and one that no computer model I'm aware of could currently match.

So I guess "baby" is an exaggeration, but "infant" or "toddler" would be more accurate.

LG's beer-making bot singlehandedly sucks all fun, boffinry from home brewing



It seems to me that there are two main reasons to brew your own:

1. It is vastly cheaper - a pint of homebrew costs about 20p, and the equipment only costs about £50.

2. You can make the recipe up yourself, tweak things, add stuff in or take it out.

For most homebrewers, it's a combination of the two.

Both of which an expensive, all-in-one, web-connected, "smart," auto sanitising, pod-relying machine will negate.

So what is the point of it, and who is the target audience?

Re: Very odd company

I ordered an XPS13 with Ubuntu on it. It was the oddest experience.

The computer took so long to ship that my card, linked to the paypal account I payed with, had expired. Instead of holding the shipment when the payment failed, they shipped anyway, and some Indian team were then in charge of trying to get me to pay.

I asked them several times to send me a simple, correct invoice that I could pay via paypal. Eventually, a couple of weeks after the laptop arrived, I got an invoice, without VAT.

By that point, VAT was their problem, and I couldn't be bothered helping them any more, so I paid it.

Some months later, I got another email, from a UK team, asking me to pay the full amount (which was apparently still outstanding on my account). I ignored that, and have never heard back from them.

I've no idea how much they think I owe them, or what will happen if I ever try to order another machine from them...

I've got the key, I've got the secret. I've got the key to another person's DJI drone account: Vids, info left open to theft


Re: So Open Source is the answer?

> Can a third party prove that there's no backdoors in the executable even if the code they give is clean of backdoors?

Assuming the software is fully open-source, it should be possible to recompile from code, and install the locally compiled binary. Assuming your compiler isn't also a DJI product, this should give you near 100% certainty.

This is how hoby-level drones currently work - Betaflight is one of the primary bits of software used for racing drones, and it is fully open source. It's trivial to compile it from source (and many people do, to make it run on unusual hardware or to disable / enable different bits of it). Although DJI's offering is more complex, it could work the same way.

Re: Autorotate to where?

>It should be easy enough to specify a deployable paraglider or similar controlled-descent device, with independent control system and say 10 mins power supply, for use when the main flight power fails.

A full-craft paraglider, with separate power supply to keep it flying for 10 minutes?

Yeah, I suppose it would be easy to specify that. I can specify all sorts of things - like a spaceship with capacity to take 100 people to mars, and return them, with a transit time of of less than 6 months. Oh, and if something goes wrong, it will automatically return safely to Earth.

Doesn't mean there is any link to physical reality, sadly.

Russian rocket goes BOOM again – this time with a crew on it


@imanidiot, I see I misread his comment, so apologies for my tone. He wasn't creating conspiracy theories but rather questioning the official line, which looks very like a conspiracy... Since he's deleted his comment, I've removed mine too.

Anon man suing Google wants crim conviction to be forgotten


Right to be forgotten

I find myself conflicted in these cases.

In some ways, it is unfair for a conviction to follow people forever, where the courts have stated a limit. Assuming ABC is not convicted with a life sentence, his conviction will be "spent" after a certain period. If old reports are damaging people beyond that period, I have some sympathy.

But then, the whole point of a search engine is to make data more easily available. Court records most certainly are data, and opening them up is a massive benefit to the population as a whole. If his conviction is not spent, and someone merely reported about it... well then, tough luck. That's part of the consequences.

What I don't quite understand is what Google et al are realistically meant to do in order to pre-emptively filter out results, or why they should do so at all. The responsibility surely lies with the people publishing the information, not the company organising it. The librarian isn't responsible for the content of a book you object to.

Space station springs a leak while astronauts are asleep (but don't panic)


Re: Small leak???

>Must be that GREAT soviet build quality we've heard all about

Are you American, by any chance? Because your stupid is showing.

Firstly, when something breaks, it is normal to try and work out why. And yes, a manufacturing fault is one option, obviously.

Secondly, the very next sentence in the article states that this is unlikely. Did you just stop reading when you came across something that seemed to confirm your slightly xenophobic stereotypes?

Thirdly, and this one is important. Why is the US relying on Russian engineering to get its astronauts into space? Maybe you should stop to ponder the inability of the US to transport its own astronauts before you take a shit on the Russians who have, by all sensible measures, won the space race.
