Comment Re:Directly monitored switches? (Score 1) 36

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.

Journal Journal: Audio processing and implications

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.

Or at least it's used as one.

And that does have it's advantages, believe it or not.

Any untrained office worker can open an Excel sheet and run the app that's built with it without any extra training or security and privilege stuff getting in the way. Office workers can build their own logic without having to shop around for some developer to take care of their problem and the ERP budget doesn't have to be touched. And it's even modern purely functional programming. ... That's how you eventually get Shadow IT that often becomes mission critical.

What SQL used to be in the 70ies Excel & VBA is today. Wether that's an improvement I couldn't really say für sure, but that's the way it is.

We know what will happen in a world where there is no need for human labour. The 'elite' will build Terminators to eliminate most of the humans.

I doubt it. The elites have capital to invest in the means of production. Absent this they have no real power or purpose.

When you no longer need to pay countless thousands of people to perform a task this is a double edged sword. It not only means you can make do with less it means anyone else can step in and accomplish the same tasks without you.

"Blaming internet or some chatbot" makes perfect sense when the chatbot was programmed to manipulate people and it manipulated a 16 year old to commit suicide.

Chatbots are trained not programmed. If you have evidence OpenAI's chatbot was explicitly trained to manipulate people then FFS please don't keep it to yourself.

Selling guns to a five year old is itself illegal under the gun control act. Walmart would be breaking the law.

New buildings might have it integrated into their HVAC systems, and older construction might have it retrofitted, but the vast, vast majority of buildings in the US do not have CO2 monitoring. We have CO (monoxide) detectors, but that's an entirely different issue.

Active monitoring is for energy savings. A buildings HVAC is designed to meet air exchange requirements given designed occupancy levels regardless.

Another consideration is that for assessment of infectious disease risk, measurement of CO2 in indoor communal spaces needs to be distributed throughout, as opposed to having a single point of measurement that might only reflect the average air quality for HVAC control purposes.

No, this is handled by HVAC system design to accommodate expected occupancy.

Disclaimer: European here.

There are well over a thousand food additives that are banned and illegal in Europe, some of which are classified as effing prime-grade toxic waste(!) - meaning they cannot even be legally disposed of in a drain or a regular landfill - that are "legal" food additives in the US.

It is proven beyond any doubt that forever chemicals accumulate in liver and other vital mammalian (read: also human) organs and cause chronic diseases beyond low threshholds and now they're supposed to be legal food additives?

This is insane. No wonder your cancer rates are through the roof.

I suggest you people raise a stink and write some letters to congress. And ramp up subsidies for organic farming and natural produce. And limit them for processed foods. US health is deteriorating at a measurable pace and you guys should want to change that.

Just sayin'.

Two thumbs up and good luck!
