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.

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.

Comment It's not just foreign languages (Score 2) 49

There's a lot of stuff that is on the Internet that doesn't end up in AIs, either because the guys designing the training sets don't consider it a particular priority or because it's paywalled to death.

So the imbalance isn't just in languages and broader cultures, it's also in knowledge domains.

However, AI developers are very unlikely to see any of this as a problem, for one very very important reason --- it means they can sell the extremely expensive licenses to those who actually need that information, who can then train their own custom AIs on it. Why fix a problem where the fix means your major customers pay you $20 a month rather than $200 or $2000? They're really not going to sell ten times, certainly not a hundred times, as many $20 doing so, so there's no way they can skim off the corps if they program their AIs properly.

Let's take a look at software sizes, for a moment.

UNIX started at around 8k, and the entire Linux kernel could happily sit in the lower 1 megabyte of RAM for a long time, even with capabilities that terrified Microsoft and Apple.

The original game of Elite occuped maybe three quarters of a 100k floppy disk and used swapping and extensive use of data files to create a massive universe that could be loaded into 8k of RAM.

On a 80386SX with 5 megabytes of RAM (Viglens were weird but fun) and a 20 megabyte hard drive, running Linux, I could simultaneously run 7 MMORGs, X11R4, a mail server, a list server, an FTP server, a software router, a web server, a web cache, a web search engine, a web browser, and stil have memory left over to play Netrek, without slowing anything down.

These days, that wouldn't be enough to load the FTP server, let alone anything else.

On the one hand, not everything can be coded to SEL4 standards (although SEL4, by using Haskell as an initial language to develop the core and the proofs, was able to cut the cost of formal programming to around 1% of the normal value). On the other hand, a LOT of space is gratuitously wasted.

Yes, multiple levels of abstraction are a part of the problem. Nothing wrong with abstraction, OpenLook is great, but modern abstraction is mostly there due to incompetent architecture on previous levels and truly dreadful APIs. And, yes, APIs are truly truly dreadful if OpenLook is the paragon of beauty by comparison.

The solution is easy. WiFi 6 is only just starting to come out in the marketplace. If TP-Link hijacks the standard development procedure, solidifies a workable WiFi 8 quickly, and manufacturers/users in Europe, Asia, and Oceana all start using WiFi 8, skipping WiFi 7 entirely, the US will be left with an inferior standard that only they have gear for, with no option to use WiFi 8 for many more years because the only manufacturers making it can't sell in the US.

There are 1500 genes involved. As effects are likely not merely down to specific genes, but gene interactions, you're going to need a model that can handle 2^1500 different permutations. That's simply not something that is classifiable.

As far as gene therapies are concerned, since autism seems to involve combining elements of Neanderthal neurology with homo sapiens neurology, the obvious fix would be to add further Neanderthal genes where combinations are known to produce adverse effects.
