Boeing making new 737 MAX software updates to address computer issue:

Boeing Co (BA.N) said late on Tuesday it will make two new software updates to the 737 MAX's flight control computer as it works to win regulatory approval to resume flights after the jet was grounded following two fatal crashes in five months.

The planemaker confirmed to Reuters that one issue involves hypothetical faults in the flight control computer microprocessor, which could potentially lead to a loss of control known as a runaway stabilizer, while the other issue could potentially lead to disengagement of the autopilot feature during final approach. Boeing said the software updates will address both issues.

The Federal Aviation Administration said on Tuesday it is in contact with Boeing as it "continues its work on the automated flight control system on the 737 MAX. The manufacturer must demonstrate compliance with all certification standards."

The largest U.S. planemaker has been dealing with a number of software issues involving the plane that has been grounded since March 2019. Boeing halted production in January. Boeing said it does not expect the issues to impact its current forecast of a mid-year return to service for the plane. Boeing said the new software issues are not tied to a key anti-software system known as MCAS faulted in both fatal crashes.

    Wow, thank you for all of that. I didn't know Fukushima was such a compromised design. I knew most of what you wrote. I could never figure out why the emergency generators were low in a building. Maybe it would have cost more to put them up higher due to stronger building framing? Maybe they wanted to keep them near the pumps they had to run?

    Wow, what a mess with the lost database. Infrequent backups? All my adult life I've thought about this stuff on many levels. We tech-types are generally not strong forceful type-A types, and usually back down when higher-ups argue against spending money on safety (whether hardware, software, whatever). I've never understood why I need to be the champion of saving the company's future. I've seen several companies completely fold (after I was out of there). I still can't figure out what happens to mgt. types. They certainly don't seem to learn from business / economic history.

    Years ago I was tasked with setting up a server, including a DB (forget which one, possibly DB2). The backup software was amazing- it constantly watched the filesystem and wrote any changes to tape on the fly. No delay.

    You also reminded me of 2 developers at that company who spent months on a very complex C/Unix project (industrial controls). Super-brilliant guys. They had lots of notes, but weren't doing backups. Near the end (or so they had hoped) the one guy gives the Unix command to copy the disk to the tape drive... but... reversed it, so he wrote blank tape to the hard disk. Needless to say it took them another 3 weeks working day and night, 7 days, to recreate the whole project. Truly good souls- everyone felt so badly for them, but they regained their good spirits within a day or two as it was all so fresh in their minds.

    DROP TABLE reminds me of that case where DB read/writes were part of a URL and in some school district a kid issued URLs with DROP TABLE in them. Oh my. Like with most such stories, the useful details never come out. Like, who did that programming? What company? How is it that we are pretty much forced into at least 13 years of "schooling" but these major life lessons are unlearned?

    > I still can't figure out what happens to mgt. types.

    I also wondered that.

    It varies. They can fall from favor, and never recover. It can take more than one disaster. 2nd chances seem to be a bit more frequent for the management class. Even 3rd chances. But it's not many, and 3 or 4 small disasters or 1 big one can finish their careers. I've seen that happen. I know at least 2 ex-managers who were demoted, and finished the last decade or 2 of their working lives on the bottom rung, no one reporting to them, just glad to still have a job, swallowing the humiliation of it all. I also know of a few other ex-managers who would not take the demotion, instead storming out and away to another job where they thought their amazing talents would be better appreciated and utilized. But there's only so much of that any manager can do before it becomes too difficult to explain to yet another prospective employer why they keep changing jobs. And I know of yet another manager who stank it up and lost the contract, and yet was actually rewarded with a promotion to VP. I can only guess he must have had a lot of valuable contacts, and perhaps the move was something of a kick upstairs.

    It also depends on how independently wealthy they are. The rich especially buy into the myth that management, particularly upper management of course, is the ultimate in careers, and won't give up trying to manage others no matter how bad they are at it. There are many elite private schools that cater to this thinking. They call it "leadership", because that sounds a lot sexier than "management". They offer a pretty good education, but not for the sake of education, no, education is but a tool, a means to an end. And what end might that be? Being in position to maximize the exploitation for their own selfish goals. Many aren't much interested in education as something pleasurable and virtuous in itself. One indication is that these schools cling to archaic and outmoded education methods that have been shown to be counterproductive, stuff such as shamings and even beatings for getting bad grades. Even if the schools themselves know better, they have to do it anyway because that's the way the parents want it. See, for example, the Robin Williams movie, Dead Poets Society.

    These rich leaders can cock it up again and again and again, and super rich Daddy will bail them out almost every time. The terrible ones are masters at self-delusion about how great they are at management, and will have an endless list of tiresomely predictable excuses about why the latest disaster is not really their fault, it's all the fault of their lazy and stupid underlings, and bad luck, cutthroat competition, and the entire body public for not appreciating their brilliant work and lining up to buy whatever it is they were making. And it was a risky proposition anyway.

    As to how someone is tapped for management in the first place, that too is riddled with problematic thinking. So often the loudmouthed ignoramus is mistaken as an aggressive go-getter. They undervalue technical knowledge and skills, and overvalue aggression and outright bullying. And you don't really think the upper class twits in charge are any good at discerning who will make a good manager, if they're no good at management themselves.

    If you are wondering why so much management is crap, that's why. Not much merit involved in choosing managers. It's also been shown that voters actually don't like a candidate who is too good, too smart. They want their elected leaders to be only a little smarter than themselves. No doubt that preference is also reflected in management.

      Well I think lots more people will follow the guy confidently saying loudly "FOLLOW ME! I KNOW THE WAY!" even if he's wrong than follow some nerd saying "I think this could be one of the better paths given the little we know at the moment".

      What can work is a confident leader sort of person who is humble and wise enough to listen to the smart people and ignore them at the right times - because sometimes you just have to make the call and take a leap (no choice sometimes).

    Higher spec works:
    https://www.oregonlive.com/opinion/2012/08/how_tenacity_a_wall_saved_a_ja.html [oregonlive.com]

    United Nations inspectors marveled this month that the nuclear plant closest to the epicenter of Japan's massive earthquake survived virtually intact, averting a Fukushima-style meltdown.

    The plant shut down so safely that it served as an evacuation center in Onagawa, where 827 died.

    But costs more, sometimes not just in money:

    Finally, Oshima said, Tohoku's president agreed to spend more for the higher wall -- before resigning to take responsibility for an electricity rate increase.

    How many would do that? I'm not brave enough to say I'd do the same thing. Keep in mind the "pesky" designer was already dead decades before the quake hit.

    If they got lucky and there was no such quake for more decades, the 39 feet would have been good enough. If they got unluckier the 46 feet might not have been good enough (but I guess the other measures might have still prevented it becoming a nuclear disaster).
