Comment Re: Has Climate Doom Modeling Turned Into Clickbai (Score 1) 129

Sorry - as a full-blown human-caused climate change believer, I am also old enough to remember being told that we were in an inter-ice age era and that it would end in my lifetime. I'm in the UK, and I clearly remember a school textbook with drawn pictures of Trafalgar Square fully iced up. This would be early 80s.

Let's not deny that bad information has been given in the past. Bad information is also likely being given today, and will be tomorrow as well. Mistakes happen. I like that this paper has been caught and do not in any way see it as a problem.

I'm seeing a lot of scepticism in the posts, whereas in fact this approach works really well. I'm going to use the example of the Mac - Rosetta 2. I play games running x86 code all the time on my M2 ARM chip, and it's not really noticeable at all. Taking exactly the same approach and applying it to Linux - yep, why on earth not? Already proven to work well.

That's actually a good question. Inks have changed somewhat over the past 5,000 years, and there's no particular reason to think that tattoo inks have been equally mobile across this timeframe.

But now we come to a deeper point. Basically, tattoos (as I've always understand it) are surgically-engineered scars, with the scar tissue supposedly locking the ink in place. It's quite probable that my understanding is wrong - this isn't exactly an area I've really looked into in any depth, so the probability of me being right is rather slim. Nonetheless, if I had been correct, then you might well expect the stuff to stay there. Skin is highly permeable, but scar tissue less so. As long as the molecules exceed the size that can migrate, then you'd think it would be fine.

That it isn't fine shows that one or more of these ideas must be wrong.

For you having an understanding of the area but not the issues. The main complaints are the noise, in particular the backup warning beeping that are required for operations. These beeps have been captured on decibel meters as hitting 112 dBA!

For reference, Santa Monica has had excessive noise ordiances on the books that the limit is for 50 dBA (for up to 15 minutes) or 55 dBA (for up to 5 minutes) between 10pm and 7am. Being that the decibel levels are a logarithmic scale, 112 dbA is actually over 100,000 times the sound intensity than the ordinance allows (a 10 dbA difference is 10x difference in intensity level). This isn't just a simple small difference. It is the difference of say a "live rock concert" vs the hum from a single, normal home kitchen refrigerator running....

What always happens when you try to block kids from doing anything: they find a way to do it anyway.

We older folks too were "blocked" from doing stuff as kids, pre- and post-internet, and we too did it anyway. And it actually made us smarter, as we had to devise ways around the obstacle.

Kids are smart. This will just make them smarter.

Investment is a tricky one.

I'd say that learning how to learn is probably the single-most valuable part of any degree, and anything that has any business calling itself a degree will make this a key aspect. And that, alone, makes a degree a good investment, as most people simply don't know how. They don't know where to look, how to look, how to tell what's useful, how to connect disparate research into something that could be used in a specific application, etc.

The actual specifics tend to be less important, as degree courses are well-behind the cutting edge and are necessarily grossly simplified because it's still really only crude foundational knowledge at this point. Students at undergraduate level simply don't know enough to know the truly interesting stuff.

And this is where it gets tricky. Because an undergraduate 4-year degree is aimed at producing thinkers. Those who want to do just the truly depressingly stupid stuff can get away with the 2 year courses. You do 4 years if you are actually serious about understanding. And, in all honesty, very few companies want entry-level who are competent at the craft, they want people who are fast and mindless. Nobody puts in four years of network theory or (Valhalla forbid) statistics for the purpose of being mindless. Not unless the stats destroyed their brain - which, to be honest, does happen.

Humanities does not make things easier. There would be a LOT of benefit in technical documentation to be written by folk who had some sort of command of the language they were using. Half the time, I'd accept stuff written by people who are merely passing acquaintances of the language. Vague awareness of there being a language would sometimes be an improvement. But that requires that people take a 2x4 to the usual cultural bias that you cannot be good at STEM and arts at the same time. (It's a particularly odd cultural bias, too, given how much Leonardo is held in high esteem and how neoclassical universities are either top or near-top in every country.)

So, yes, I'll agree a lot of degrees are useless for gaining employment and a lot of degrees for actually doing the work, but the overlap between these two is vague at times.

Comment Re:Directly monitored switches? (Score 1) 54

There is a possibility of a short-circuit causing an engine shutdown. Apparently, there is a known fault whereby a short can result in the FADEC "fail-safing" to engine shutdown, and this is one of the competing theories as the wiring apparently runs near a number of points in the aircraft with water (which is a really odd design choice).

Now, I'm not going to sit here and tell you that (a) the wiring actually runs there (the wiring block diagrams are easy to find, but block diagrams don't show actual wiring paths), (b) that there is anything to indicate that water could reach such wiring in a way that could cause a short, or (c) that it actually did so. I don't have that kind of information.

All I can tell you, at this point, is that aviation experts are saying that a short at such a location would cause an engine shutdown and that Boeing was aware of this risk.

I will leave it to the experts to debate why they're using electrical signalling (it's slower than fibre, heavier than fibre, can corrode, and can short) and whether the FADEC fail-safes are all that safe or just plain stupid. For a start, they get paid to shout at each other, and they actually know what specifics to shout at each other about.

But, if the claims are remotely accurate, then there were a number of well-known flaws in the design and I'm sure Boeing will just love to answer questions on why these weren't addressed. The problem being, of course, is that none of us know which of said claims are indeed remotely accurate, and that makes it easy for air crash investigators to go easy on manufacturers.

Just as a thought experiment, I wondered just how sophisticated a sound engineering system someone like Delia Derbyshire could have had in 1964, and so set out to design one using nothing but the materials, components, and knowledge available at the time. In terms of sound quality, you could have matched anything produced in the early-to-mid 1980s. In terms of processing sophistication, you could have matched anything produced in the early 2000s.

It's far from indisputable. Indeed, it's hotly disputed within the aviation industry. That does NOT mean that it was a short-circuit (although that is a theory that is under investigation), it merely means that "indisputable" is not the correct term to use here. You can argue probabilities or reasonableness, but you CANNOT argue "indisputable" when specialists in the field in question say that it is, in fact, disputed.

If you were to argue that the most probable cause was manual, then I think I could accept that. If you were to argue that Occam's Razor required that this be considered H0 and therefore a theory that must be falsified before others are considered, I'd not be quite so comfortable but would accept that you've got to have some sort of rigorous methodology and that's probably the sensible one.

But "indisputable"? No, we are not at that stage yet. We might reach that stage, but we're not there yet.
