I don't think it was me, but I remember that discussion a bit. I also remember reading in several places that the MD-11 was an evolution of the DC-10, which was the plane that had the engine mount (pylon) problem, engine breaking away, total hydraulic loss, uncontrollable plane, 273 fatalities.

https://en.wikipedia.org/wiki/American_Airlines_Flight_191

They didn't blame the pylon design, but rather improper engine removal / installation that damaged the pylon. I would have liked to see that pylon being a bit bigger and tougher, not just-so. IE, more margin for error in such a very critical part.

Yeah, at first I was wondering if it was me. I didn't think Welch was directly involved at Boeing, and a quick web search confirms he wasn't.

But it's fair to say his cutthroat business philosophies infected most all major manufacturing companies, namely profit being top priority.

I wonder if once they've sold the data to whoever (evil) entities that want it, there's no more market for that particular data, so they don't mind "deleting" it.

Yes, fake job listings have always been around, for many reasons. Here's an oxymoron: "business ethics", should be "business lacks ethics". If they had to pay applicants for the time wasted applying for fake job ads, maybe things would improve (would require some kind of class-action lawsuit of course).

In the 90s I worked at a small medical equipment company, mostly doing IT, systems, some coding. One day the VP walks in to my office, plops a resume on my desk and asks me to interview a guy. I didn't know we were hiring, I knew nothing about the supposed position or the applicant. I skimmed his resume and chatted a bit. Turns out that company was literally fishing for free engineering / design ideas. Very clever of them, but I believe in ethics and I was very disappointed, felt a bit used / dirty, and for that and many reasons left the company a few months later.

If I see a company hiring, it's reasonable to conclude they're doing well and might have good future.

If a company is laying off, sure they might be short-term cost-cutting / profiting, but I would be concerned about their long-term.

Maybe investors are learning? Maybe AI's learning is helping investors see bigger picture?

You're all correct. In my area (East Coast USA major city suburbs) where there's a non-working traffic light they just blow through. Same if it's flashing red, which means STOP, but people fly through at full speed limit speed or more. Cops rarely around. But there are more and more traffic light cameras, so I'm not sure but maybe they're receiving tickets.

They barely stop for working ones.

Sounds like a Waymo vehicle could not pass a standard driving test. As in, "what is the rule when you come upon an intersection where the traffic lights are completely out?"

Shhh!!! Don't let any cancers hear you.

I think parent was asking how to undo the damage already done by the autoimmune attack. It may not be fixable, depending on what's been damaged, how badly, etc.

CAR-T is interesting. Not a biologist, but I'm hoping that and similar technologies can be used to program immune cells to destroy viruses like E-B.

There exist antiviral drugs too. Dr. House liked acyclovir. (Do people know Hugh Laurie's father is (was?) a real doctor?)

I too had a pretty bad case of mono around age 20. A good friend, very strong and fit, had it in his mid-30s, and IIRC he ended up hospitalized. He always thought he was getting allergy attacks, and would get so run down he'd have to hole up and disappear for a few days every now and then. My bet is he was getting too run down, not enough immune-boosting sleep, and E-B would overwhelm his system.

Thanks for the shingles vaccine tip. I'm NOT an anti-vax person (sheesh) but I'm not big on needles, nor things that might cause problems if I don't think I need it. IE, it ain't broke, don't fix it. That said, Dr. said I should get a once-in-a-lifetime vaccine earlier this year- covered several things including some viral pneumonias. I'm not sure if I had reaction to it. Nothing acute, but maybe psychosomatic feeling a bit "off" for months afterward.

Question is: I'm not sure if I had chickenpox. How do I know if I need shingles vaccine?

Your answer makes sense, but then my question becomes: why allow the runway expansion? We've seen several airplane accidents fairly recently that might have been less disastrous if there were flat fields past the end of the runways. One way or another it should be an absolute no. (Suddenly I feel like Ralph Nader or someone in the 50s or 60s campaigning for seat belts in cars...)

There's a small airport near me- supposedly small jets can fly in and out. Used to be empty open space at the ends of the runway, but they've allowed high-density condo development just next to the end of the runway. Complete idiocy. I can't imagine who would want to live there. Noise, danger, crazy.

Absolutely agree. But my first reaction to this accident was (and is): why are they allowing so much stuff- buildings, etc., right past the end of a major runway?

Sorry for late reply: in such a use case you'd select the fuse specs to match the need- hold current, trip current, etc. I only did a brief skim of available ones but there are many that would work well. Forward resistance is extremely low for these types of currents, on the order of milliohms and sub-milliohms, so I^R losses would be nil.

I'm not sure why they're not used, but when I get a chance I'll ask a very genius EE I know. My hunch is they just don't want to add the cost.

I have some experience installing PV systems (here in US).

Must be online? I'll do some research, but that sounds worrying. I wouldn't mind a passive monitoring system being online, but I would not want the inverter itself potentially vulnerable to attack.

The inverters I've installed simply sense the grid's demand for electricity and vary their output accordingly. Not sure why one would need remote control of an inverter.

Disclaimer: I'm an EE but haven't researched this, this post is not authoritative. It's just meant as an idea tossed out there for possible discussion.

Have you or has anyone thought about using self-resetting fuses on each battery? That won't solve every scenario, but should make a lithium-based battery pack much safer. One would need to find out the full operating safe areas (temperature + current) to decide what the fuse specs need to be. Of course then lower the fuse amp limit even more for safety margin. Determine how much current your device needs then figure out how many cells you need in parallel.

Of course if the cell shorts internally it's boom. AFAIK that's usually due to cells being packed tightly with no room for normal expansion.

Some years ago I stumbled on an article about Li-ion cell recharging. Not sure if the article was authoritative- I didn't do much more research. But it said you don't want to charge Li-ion with constant current, that something bad happens. They want constant voltage, which might be a lot of amps initially. But then you have to limit the charge time, all while monitoring temperature. Of course that's all do-able, and normal Li cell packs have circuitry to do that.
