Comment Re:Fukushima and Chernobyl not worse case failures (Score 1) 227

I can't speak to the chemical plants near you but with nuclear power, you always have incredibly dirty radioactive materials inside a container, with lots of complex plumbing leading into it, and under worst case conditions that stuff can potentially always get into the air and water and get spread far and wide.

Although in principle we could make it never fail over the lifetime of human beings, in practice, we as a species, don't know how to do that, and the proliferative effects of nuclear power and their association with nuclear bombs cannot be underestimated either.

To make nuclear power completely safe, is like trying to make water not wet. It's built into the nature of what we are doing with the materials, for utility-scale nuclear power they are always on the edge of melting down.

Because of these inherent properties it's also never been cheap; the extensive containment and safety you need to engage in, seriously impairs the economics and what you have to do to get around that problem, renders it an inflexible source of power. You have to run it essentially flat out to get the kWh price down to reasonable figures. The most successful systems (like in France) have hydroelectricity or other additional flexible supplies to balance out the power. But if you have that anyway, then overall, technologies like wind power are now usually cheaper and incredibly less risky and easier to install, and compared to nuclear power which is a more mature technology, still getting significantly cheaper over time.

Throwing money at such inherently risky technology like nuclear power to try to make it less risky is not a wise investment right now, and all the signs are that it is only getting less wise with time, other technologies are rapidly rendering it moot.

They prove that string concatenation (in memory) is slower than writing to buffers (in memory).

I.E. that :

char *s, *new;
new = malloc (len + 1);
memcpy (s, new, len);
new [++len] = 'x';
free (s);
s = new;

is slower than:

buf [len] = x;
if (++len > sizeof buf) {
  write (out, buf, len);
  len = 0;
}

What a fucking joke.

Comment Fukushima and Chernobyl not worse case failures (Score 3, Insightful) 227

In Japan, they found at one point that there was a possibility of it *seriously* going to hell in a hand basket.

If the wind had been really wrong, it would have put serious fallout over Tokyo; which would have been really, really, really bad. While few people would have died, the economic disruption would have been (without any hyperbole) unbelievably stupendous.

You can tell me all you want that this kind of accident can never happen, but I just don't believe it. We have no reason to think that Chernobyl or Fukushima were the worse cases, nor that these kinds of failures cannot happen again worse.

Which makes sense. Sea level rise in the last 50 years has amounted to about 4 inches, probably not enough to make drains run backwards.

The way sea level rise will make itself known isn't through changes in day to day phenomena, but in exceptional phenomena like storm surge flooding. This is a place where inches may well matter. People plan around concepts like a "ten year flood" or a "hundred year flood", and this creates a sharp line on the map where there is no sharp line in reality. Depending where on the domain of the bell curve their chosen planning horizon is, a few inches could turn a ten year flood into a five year flood, which has immense practical implications.

When people way that there is nothing intrinsically worse about a globe that's four degrees hotter they're right. But *change* that undermines human plans represents a big challenge. Change also represents a big challenge to species populations that can't relocate on the timescale of change.

Having fun isn't necessarily stupid. Having fun with flamboyantly dangerous things isn't necessarily stupid. It's endangering unwilling bystanders that's stupid.

Some people like to build and shoot powerful crossbows, or even replicas of medieval siege weapons. These are extremely dangerous and useless things. The dangerous power of a trebuchet to throw an upright piano 150 yards is part of the charm.

But a trebuchet is something that takes certain amount of thought and sacrifice to obtain and use. This flamethrower thing is more like a powerful handgun. There's been a recent fad for ridiculously overpowered handguns, which pack superfluously fatal power into a convenient, affordable form factor. The recent brouhaha over "armor piercing" ammunition was a side effect of a manufacturer selling a cut-down semi-automatic carbine as a "handgun", even though if you look at videos of people using them they're obviously terrible as handguns. This raised the question of whether 5.56 NATO ammunition should be regulated as "handgun ammunition", and in the end I think the decision not to was reasonablee. These aren't cop-killing or military handguns. They're extremely dangerous toys designed to get your rocks off.

There are some who'd say that because these guns are dangerous and impractical they should be banned. But I don't agree. "Impractical" isn't the same as "useless" because getting your rocks off is a legitimate use for a thing. I think people should be able to enjoy their ridiculous firearms as long as they do it at some kind of appropriate range. I also think there's a real danger though from stupid people who will go plinking in the woods with the things like they were BB guns.

That's really the only problem I have with this flamethrower, whether it's gold, chrome, or gunmetal gray. Any idiot can buy one, but it'd take someone reasonably intelligent and determined to find a place where it can be used safely. I'm not against people buying them, but I am for coming down hard on people who use them where they're a danger or public nuisance.

Well, in the end you have to ask "did he get away with it?". Or, given that he turned himself in later, "did he have some purpose in escaping that he fulfilled?"

Intelligence is a multi-dimensional phenomenon. It includes things like thinking through unintended consequences before acting that quite clever people are sometimes bad at.
