I do not want cheaper, I want quality at a reasonable price. Sometimes I even accept an unreasonable price for the quality (think Apple stuff). I will never buy crap at cheapest bargain prices.
Cheap clothes barely survive a couple of washes, good quality clothes survive much, much longer. Yes, they are more expensive short term, quite a bit less expensive long term.
Also, not once, ever, was my buying decision influenced by an ad. What influences my decisions is the problems, the defects i will have, or not, with what I chose to buy. Usually, the longer time it works the more expensive it is.
That file doesn't seem like it would work for a number of reasons.
The gear with integrated hour hand wouldn't be able to rotate in the space that it's mounted. In order to tell the time against the ring, the hand would need to be much further away from the gear.
Secondly, the funnel bit seems to have no real purpose; if you have to pipe water to the funnel, why not just bring it directly to the cup at the bottom? In real water clocks there is usually a primary collector but it's built in such a way that it overflows at a certain level so that the pressure on the outgoing line stays constant. The funnel here does essentially nothing and there is nothing else in the clock that would provide any kind of flow rate calibration; you'd have to do that externally.
Lastly, it's not clear how you'd reset the clock. Can the collector be removed separately or do you need to turn the whole clock upside down to pour the water out and get the float back down to the bottom?
Like Boeing, there was organizational dysfunction leading to a direct safety issue.
During the development of the A380, the German and French sides were using different versions of the CATIA PLM software (i.e. CAD), which prevented people from looking at a single unified model of the plane. One concrete problem it caused was major problems with the wiring harnesses, which led to a 2 year delay in the program, and 3 early A380's which couldn't be sold. (Airbus kept one for test, the other two got sent to museums)
That manifested in this accident because the wing wiring was routed through the engine disk burst axes (a hazard which is explicitly accounted for) with insufficient redundancy. That created the dangerous situation where they couldn't turn off the engine after landing.
The vastly preferable situation was to have redundant wiring that properly complied with regulations, which was retrofitted in an airworthiness directive (safety recall) after the accident.
They also required engine software that detected the sudden increase in speed associated with a shaft break and automatically cut fuel.
Sort of. Rolls Royce voluntarily developed this software modification in response to learning that their reasoning about it never being able to happen was incorrect and being unable to concretely account for how it happened. EASA, which was not even the relevant safety authority for this incident, upon learning of its existence, only then required it to be installed on all A380 Trent 900 engines.
The plane was a significant factor but you really shouldn't look past the calibre of expertise in the cabin on this particular flight.
> 5 pilots were in the cockpit of this flight. In addition to the normal crew of pilot-in-command and co-pilot, there was an experienced relief pilot and two additional check captains; one was being trained as a check captain (CC) and the supervising CC, who was training the CC.
Captain Richard Champion de Crespigny had 35 years of flying experience at the time of the incident.
That is an insane amount of flight experience in the cockpit and all of the reports state this was a very significant factor. i.e by allowing distribution of the task load, plenty of time for one of the pilots to compute landing calculations manually etc.
THe A380 is a flying tank no doubt, but it wasn't the sole factor here - I think most people would agree this one was a shared victory.
It was probably helped by the fact that airbus didn’t try to pretend that the aircraft was just a slightly different version of some previous aircraft and therefore doesn’t require any additional training lol.
What’s the alternative? I think averaging with a dual input alert is a pretty good solution. Otherwise you need to find a solution to transition from one stick to the other. You can’t just switch sticks with the press of a button because the input could jump from elevator up directly to elevator down for example.
The state-held stakes are mainly French, German and (less) Spanish. The UK taxpayer currently owns 0% of Airbus, though the UK gets the business of building wings and landing gear.
I thought this was a strange insertion of geopolitics into the conversation so I checked out this account’s comment history. It’s good for others to see that some commenters here have a serious axe to grind and are not really “hackers” as their primary interest here. The most recent comments in order:
> [something about london taxi drivers, admittedly unrelated]
> I totally get you and in theory you are right.
And yet, in the USA you have gerrymandering and apparently _wanted_ Trump. Twice. Something has to be very wrong somewhere.
> I would suggest "lobbying" is not the correct word to describe all the corruption going on in the current USA administration cesspool.
>I recently bought a BambuLab 3D printer.
Designed and made in China. Right from the unpacking to first print the experience was top Apple-style quality. Indeed I was agreeably surprised.
> A global non USA success? Plenty. You might want to remove your pink USA glasses and look around. Spotify good enough for you?
> I am Canadian. Never, ever would i knowingly buy any dairy products from the USA , at any price.
We have cows too, and farmers.
> Its not that it hates its customers , as much as it it a USA-based company that is run under the rules made by the administration. Not that much different from running Red Star OS from North Korea, actually.
Well ... It takes four years of education before becoming a taxi driver in London: https://thetaxi.academy/
It takes also many years of study before they will let you touch any living person with your scalpel, and then many years of apprenticeship with actual surgeons when you do touch people with your tools.
I can imagine maintaining a big jumbo jet also requires some specialized practical knowledge you cannot acquire just by reading books and looking at nice little
videos.
The problem is not to explain things when everything works perfectly. The problem is getting the ability to diagnose the root causes of defects using all your senses and your intuition. That is not taught in books.

I’ve only been to London once, for work. One of the coolest things I did when I was there was to take a black London cab from the financial district to Heathrow when I was leaving. It was probably a 30 minute drive. The driver had been driving a cab since 1982. He told me all about the requirements and training for being a cab driver and a bunch of other things that I did not know (for example, they own the cars, and they can choose when they work). He was also a wealth of information about London, as you can imagine, and pointed out lots of interesting things as we drove.
It was probably a $50 cab ride, but worth every penny (even though it wasn’t my money since it was a work trip).
There are detailed step-by-step instruction cards (task cards) for every single maintenance operation on an airplane. Nobody is reinventing the wheel, they’re carefully following predetermined procedures. Someone has to figure out which maintenance procedures need to happen, but the work itself is laid out for you step by step.
This seems like a fast-track to making airline mechanics a minimum-wage, any-guy-off-the-street kind of job, which is not who I want touching the plane I'm flying in.
There needs to be SOME accountability. "Oh, but my glasses told me to unscrew this bolt, I was just following orders." is not how I want the future to be.
We worked on a proof of concept using HoloLens for an engine teardown team at a trucking OEM. Ran into issues around network, security, the Hololens itself and a general disinterest from the teardown team but there's a lot of room to run in this space. It was a fun, if frustrating, project.
(In case you're not aware) It's the same thing. Uber operates in London as private hire operator, so their drivers are mini cab drivers. Same rules (now: basic English and rules test, yearly car inspections, MOT every 6 months, cars must have TFL badges, etc).
It's kinda funny to hear these protests. In a "true fascist" society, you wouldn't be surprised to see someone killed in the name of political power. But in a "true capitalist" society, you're shocked that money triumphs over virtue? It's not a "virtuist" society, is it?
Authoritarian capitalists exist. Larry Ellison, Alex Karp, Elon Musk, Mark Zuckerberg - they love when you think that capitalism plays by written rules. It helps them use your tax dollars to pay for their surveillance services. It helps them sell you B2C products that degrade the moral fabric of America, and rewrite legislation through online influence campaigns. You can say it "isn't capitalism" because you don't agree with it politically, but the accrual of capital is precisely how all 4 of those men became powerful. Their influence on social media is why they're able to reframe the national discussion how they want. Their money is what lets them turn political willpower into a business, or a rubber chicken into a politician.
After all, what is Reddit or 4chan if not one big capitalist influence campaign? Do you really think product reviews and political ragebait is driven by some natural and benevolent social force that we can't see or feel?
Its Apple'esque. The edge are still rough, and I don't trust their sketchy antics. People buy Apple because they earned that trust among their customer base. Is the device better than competitors, in my opinion yes but they are more along the lines of Samsung and not Apple.
Caveat: (Yes I know geeks here will say apple users are just dumb and want a status symbol....they'll never get it)
My comment was not say Prusa is inferior, but just to mention that "Made in China" today is really not like the "Made in China" of the 1970s.
BTW I know nothing about 3D printers, but the Bambulab was recommended to me by a German friend who lives in Germany and is all about open-source ... He had printers since a long time and knows the ecosystem very well.
He told me the BambuLab printer was better for me because less tinkering, and much cheaper, at similar quality... which is what i was looking for.
We both are embedded systems engineers who work with Linux daily, so I trusted him. The results I get from the printer do not disappoint.
However I totally get the Prusa vibe. Just not for my specific use case.
Be afraid...
