Whatever happened to IPv6 ?

I didn't do anything crazy like actually read the article, but I did go as far as to read the third sentence of the summary, which began like this:

[A]round half of internet traffic continues to use IPv4, because changing to IPv6 can be expensive and complex [...]

.... and that would seem to indicate that IPv6 is currently handling around half of Internet traffic.

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.

Stop chasing these false "scarcities" that continue to crop up from time to time. Build your systems with used or NOS parts that are 3 or more generations back.

That's good advice for individuals building a home system for personal use. It's not really applicable for businesses and companies, though, since they likely don't have the expertise or the man-hours required to cobble together their business-critical systems from used parts. They're going to want to buy new, from a company that give them good support if/when anything goes wrong.

The [AI] infrastructure isn't going to get shut down and sold off it's going to get used.

It'll get used, if using it is more profitable than letting it go dark. Given the infrastructure costs of keeping all that hardware running, it's not a given that it will be. Once the investor $$$ stop flowing and the debt limits are hit, we'll see how much of the AI hardware build-out can really pay for its own room and board, and how much was just 'peacock feathers' whose only real purpose was to impress gullible investors into handing over their money.

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.

So the 'hyperloop' people have a cool website; while the 'train' people are just plain getting on with building stuff; whether conventional or the now-quarter-century-ish old maglev option.

Looks like someone signed up for another round of 'faff with apps vs. offshoring our entire high tech supply chain' and hoped it would work better this time.

And some dumbass 'managing director' is telling us that a gigantic safety-critical vacuum system is 'not effected by strikes'; more or less because he has no idea what the maintenance and operations would involve? Truly a joke telling itself.

Comment Re:Fungus vs plant (Score 4, Insightful) 35

It's kind of a suprising to me that it was a fungus and not a plant that developed this ability. After all, plants already feed on elecromagnetic radiation.

The chlorophyll in plants is finely tuned to absorb specific wavelengths of light. It already has a hard time with green light compared to blue light, and it's simply not going to work at all with radiation that has wavelengths that are orders of magnitude shorter. Chlorophyll acts like a little antenna that gets excited by certain light frequencies, but ionizing radiation would just blow the chlorophyll molecules apart and destroy them.

Taking advantage ionizing radiation is going to require a completely different mechanism than plant photosynthesis, just like you can't use glass lenses or parabolic mirrors to focus X rays or gamma rays. Plants probably have no more chance of having such a mechanism than fungi do.

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.

people on benefits always find constructive things to do with their time, they never get depressed due to lack of purpose and end up on drinks, drugs or in prison.

You're not thinking it through -- the goal isn't just to put everyone on benefits and make them spend the rest of their lives clicking the TV remote and waiting for their next welfare check. If you want to do it right (and the robots provide sufficient surplus resources to support it), you go a step further and hire people to do the job they always wanted to do, whether it makes a profit for anyone or not. If that means we have 100,000 ski instructors and 300,000 mediocre artists, then so be it; the robots do the grunt work, and the people are paid to do their preferred avocation.

Not that I expect that to actually happen, of course; in the event the robots actually can replace all labor, the upper classes will make sure that economic surplus goes to themselves, with only the absolute minimum getting distributed to anyone else.
