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.

It's easy to have unique keys in your spreadsheet so that you can easily relate information on different sheets to one another. The problem is, actually doing the processing that a SQL server would do trivially is irritating, and then it will be processed slowly every time. Whatever Excel does or doesn't cache, it isn't enough. You can do big complicated things, but they work slowly, and maintaining it is irritating at best. When you do complicated things either your formulas get long, or you wind up having to write code, or in fact often it's both. At that point you're way better off IMO doing it in something else so that at least performance is good when you're done, and you never have to screw with editing a long formula.

But, is 2e7 cells really that many? If I spent 5 minutes brainstorming I could probably think of 20 pieces of metadata you'd want in columns of a spreadsheet tracking financial transactions

That's exactly why it should be in a database and not a spreadsheet. Spreadsheets are best when you have a reasonably limited number of columns. It's also a horrible PITA to use them as a relational database (it's more or less possible, but you don't want to do it) so hiding pieces of that complexity in other sheets in order to limit the data the user interfaces with on the main sheet is just a lot of extra work you wouldn't have to do if you used another solution.

I'm mostly surprised that Google Sheets chokes on what feels like a fairly small amount of data. My best guess is that it's some insane formulas that it struggles with more than the number of cells.

It doesn't really matter where it fails, if Excel can do it and Sheets can't then Google has to admit inferiority to Microsoft which is never a good look.

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.

When in the last two centuries have the French, or the British, or the Germans, or the Belgians, or the Italians moved in a way to unify that continent to stand up to this kind of genocide?

Biden went around congress to fund a different genocide. Pretty words, but living up to them is another matter.

Comment Re:Europe has itself to blame for this (Score 3, Insightful) 239

Eastern Europe was screaming about how dangerous this was, but they weren't listened to.

One of the most insane things is how after Russia's surprisingly poor military performance in the Georgian war, the Merkel government was disturbed not that Russia invaded Georgia, but at the level of disarray in the Russian army, and sought a deliberate policy of improving the Russian military. They perceived Russia as a bulkwark against e.g. Islamic extremism, and as a potential strategic partner. They supported for example Rheinmetal building a modern training facility in Russia and sent trainers to work with the Russian military.

With Georgia I could understand (though adamantly disagreed) how some dismissed it as a "local conflict" because it could be spun as "Georgia attacking an innocent separatist state and Russia just keeping their alliances". But after 2014 there was no viable spin that could disguise Russia's imperial project. Yet so many kept sticking their fingers in their years going, "LA LA LA, I CAN'T HEAR YOU!" and pretending like we could keep living as we were before. It was delusional and maddening.

The EU has three times Russia's population and an order of magnitude larger of an economy. In any normal world, Russia should be terrified of angering Europe, not the other way around. But our petty differences, our shortsightedness, our adamant refusal to believe deterrence is needed, much less to pay to actually deter or even understand what that means... we set ourselves up for this.

And I say this to in no way excuse the US's behavior. The US was doing the same thing as us (distance just rendered Russia less of a US trading partner) and every single president wanted to do a "reset" of relations with Russia, which Russia repeatedly used to weaken western defenses in Europe. And it's one thing for the US to say to Europe "You need to pay more for defense" (which is unarguable), even to set realistic deadlines for getting defense spending up, but it's an entirely different thing to just come in and abandon an ally right in the middle of their deepest security crisis since World War II. It's hard to describe to Americans how betrayed most Europeans feel at America right now. The US organized and built the world order it desired (even the formation of the EU was strongly promoted by the US), and then just ripped it out from under our feet when it we're under attack.

A friend once described Europe in the past decades as having been "a kept woman" to America. And indeed, life can be comfortable as a kept woman, and both sides can benefit. America built bases all over Europe to project global power; got access to European militaries for their endeavours, got reliable European military supply chains, etc and yet remained firmly in control of NATO policy; maintained itself as the world's reserve currency; were in a position that Europe could never stop them from doing things Europeans disliked (for example, from invading Iraq); and on and on - while Europe decided that letting the US dominate was worth being able to focus on ourselves. But a kept woman has no real freedom, no real security, and your entire life can come crashing down if you cross them or they no longer want you.

They clearly didn't even use a proper image generator - that's clearly the old crappy ChatGPT-builtin image generator. It's not like it's a useful figure with a few errors - the entire thing is sheer nonsense - the more you look at it, the worse it gets. And this is Figure 1 in a *paper in Nature*. Just insane.

This problem will decrease with time (here are two infographics from Gemini 3 I made just by pasting in an entire very long thread on Bluesky and asking for infographics, with only a few minor bits of touchup). Gemini successfully condensed a really huge amount of information into infographics, and the only sorts of "errors" were things like, I didn't like the title, a character or two was slightly misshapen, etc. It's to the point that you could paste in entire papers and datasets and get actually useful graphics out, in a nearly-finished or even completely-finished state. But no matter how good the models get, you'll always *have* to look at what you generate to see if it's (A) right, and (B) actually what you wanted.
