And to emphasize my point, what is the computation that actually is being performed? It's not "solving the double spending problem" or the other related problems. It's a computation which allows BitCoin issues to be addressed by attaching important BitCoin features, particularly bitcoin creation and transactions to the proof of work of the computations. As a result, we can substitute any other computation which has similar enough features to generate a proof of work and requires significant computation to perform.

No, you don't understand what work they are performing now and how it breaks things if they are not doing it

I do understand what they are doing now. It doesn't significantly change the system, if the computation work has outside utility.

Bitcoin would no longer solve the double spending problem which would defeat the point.

That is incorrect.

The Sun is a stable G2 dwarf, and over the short term (millenia/eons) its power output is stable to parts per ten thousand.

Sure, I really would like that to be true too. But that "fact" doesn't explain the Maunder minimum which appears to be a fluctuation in solar power output considerably greater than the threshold your assertion. I notice that some researchers are actually claiming that a 0.2 W per square meter change in solar output somehow causes climate changes on par with a supposed 2 W per square meter heating today from greenhouse gases (other than water vapor).

I think this is typical of the current silliness in climate research that one can assert without supporting evidence that solar output doesn't change significant on the scale of millennia while ignoring the only known solar fluctuation which correlates with significant climate variations of the time.

Really? We in countries with single payer are clamouring for a system more like America's? That's fresh. America's healthcare system is a boogieman concept here, the sort of thing that one scares voters with - "my opponent's policies will make out healthcare system end up like America's!" Even conservative Americaphiles are usually scared of it.

Comment Re:THIS will drive the adoption of the auto-driver (Score 1) 228

*Certainly* the autodriver will not be able to "handle" a rig in the context of a terminal; there are just too bloody many variables to see that happening soon. But for the bulk of long-haul miles? I can certainly see a sort of 'local pilotage' system developing where trucks are driven by a human to a terminal on the outskirts of a metro area. From that point the human gets out and the autodriver takes it to a similar terminal at the destination city, where a local 'pilot' gets in and handles the truck from there.

In other words - reinventing a less efficient version of the railroad.

I suppose its not a bad thing to have just in case but I don't see the reasoning behind the fixation on it as a design requirement and their ranting about its "importance" in press releases. In almost 300 manned space launches a Launch Escape system has only been of verifiable use in a single incident(Soyuz T-10-1).

My wife and I have owned vehicles with airbags for nearly twenty years. By your logic, we could have gotten rid of them since we never needed them.

Until a week ago.

Also, SpaceX has done something rather clever. The abort propellent and engines will eventually be used for propulsive landings instead of coming down under canopy. So their abort system isn't a total waste.

Clever in some respects - but not without risks and drawbacks. (As compared to the toss-it-unused style generally in use otherwise.) Since the spacecraft is (intended to be) re-useable up to ten time "without significant refurbishment", all limited life components (notably the seals) have to last that long. Since it's carried the whole flight, the system has to survive all flight phases. And most notably, it increases the orbited, suspended, and landed weights.

Another consideration is that "traditional" (solid fueled tractor escape motors) were passively stable, while Super Draco very likely is not. "Traditional" systems could also be easily designed to passively steer the vehicle clear of the boosters trajectory, while Super Draco will require active throttling.

I'm not saying anything against the system, only that the cleverness comes with costs that aren't going to be obvious to the untrained eye.

I'll reiterate: People here think it's a ridiculous product. The page is stupid marketing to foreigners. Yes, there are separate accent and apostrophe keys (in case you're curious, here's what an Icelandic keyboard layout looks like). Hákarl (the fermented shark you refer to) isn't eaten commonly, it's actually fairly rarely eaten (though some people do like it). Most of the foods you'd consider weird are rarely consumed, like sheep heads, skate, etc, often associated with a particular festival or whatnot. Probably the only things you'd find weird that are eaten fairly commonly are horse and fish jerky (harðfiskur). Lamb is commonly eaten here but you probably wouldn't find that weird. We also have a lot of dairy products you don't have but I don't think you'd find most of them that weird. Anyway, probably the most commonly-eaten food here is pizza ;) Hamburgers and hotdogs are common too (though our hotdogs are made of lamb).

Whale is eaten here but rarely. Nearly half of the catch consumed in Iceland is eaten by tourists (a large percentage of which, I should add, come from America). Also I'm continually surprised by the percentage of Americans who criticize Iceland for whaling but don't know that America whales too, and no small amount (producing thousands of tonnes of whale meat per year). Yes, they're "natives" whaling, but 1) it's no less traditional for Icelanders to whale than it is for Alaskan natives, 2) Alaskan natives use modern equipment for whaling too, including chasing them down in speedboats, killing them with modern equipment, and dragging them on shore with backhoes; and 3) Alaskan whales end up no less dead than Icelandic ones. None of the Icelandic whale populations are threatened.

Anyone who wants to discourage whaling over here, a few tips.

One, don't come out with the self-righteous stuff, because it doesn't fly. Not only does the US whale too, but receiving lectures on morality from a country where a majority of the population supports torture and who engages in all sorts of obscene human rights abuses and whose domestic livestock are mostly raised in factory farms in horrible conditions doesn't exactly come across well.

Secondly, know that any overt pressure is just going to cause backlash, and the more overt, the more the backlash. Many of you may see for example Paul Watson as a hero. Here he's seen as a ecoterrorist; he literally sent people in to sink ships right in the public harbour. If you want to be taken seriously, you need to distance yourself from these sort of people. You don't make friends by talking up people who come in and wreck up the place.

Third, understand the local perspective. It's not only that they've been eaten traditionally since Iceland was settled (indeed, the word for "beached whale" also means "jackpot" or "godsend", because in the old days it could mean the difference between life or death for a whole town). It's that they live free out in the open ocean, growing up their whole lives unhindered by man (except when, say, a NATO ship uses a super-powerful anti-sub sonar in the area or whatnot :P), living a pretty much idyllic life - and a single whale provides a vast amount of meat. Meanwhile, pigs for example - also highly intelligent animals - grow up in horrible squalid conditions in many of the countries that criticize Iceland .

Fourth, there are actual arguments you can make that have effect, and have on their own been discouraging whale consumption - but which foreigners who oppose whaling rarely make. Probably the foremost of these is the health issue. Whales, being top predators, tend to have dangerously high levels of heavy metal and organic pollutant contamination. If you want to make someone feel uncomfortable about eating whale meat, point out how much mercury and lead they're eating in that serving. There are also lesser arguments you can make that may or may not have effects on the person, depending on the individual - intelligence (but you better be well versed in the scientific literature, unbacked claims won't fly), for example, or how long it takes a whale to die versus other types of animals slaughtered for meat - but depending on the person, that may or may not be seen as a good argument. But the toxin contamination issue will have an effect on pretty much everyone.

(also, realize that not everyone here eats whale at all, and most people who do eat it only rarely)

Lastly, focus on the tourists. They come in for just a couple days and yet a large chunk of them order whale while they're here. Many of them oppose whaling back home, but it's as if when they come here their strict "morality" goes out the door, in the interest of "trying new things". I don't think they realize that they eat such a large percentage of the Icelandic catch, or that they somehow disconnect from where the meat comes from. There's a campaign here called "Meet Us, Don't Eat Us", encouraging whale watching instead of eating whale meat, and I think that's a very good strategy. The whale watching industry is economic counterpressure to the whaling industry.

(As a side note - I say all of this as a vegetarian).

So there could be two groups, those who look to improve their skill, who quickly distance themselves from the group that doesn't. Of course, there will still be wide variance in skill between the members of each group. I'm sure you can think of other ways it could happen.

No, I can't. I started out and I sucked. I got better eventually through experience. In order for it to be truly bimodal, people have to start in either camp A or camp B and end in the same camp they started in. Because if you transition from one to another over time, any point in time will capture a group of people in between the modes. Now, you can argue that people don't spend much time in between those modes but you haven't presented any evidence for that. What's more likely is you have geocities coders on one tail and John Carmack/Linus Torvolds on the other tail. And in between are people like the presenter and I. And since I'm not instantaneously going from bad to good, the reality of the situation is most likely some degree of a normal curve filled with people trying to get better at programming or even just getting better though spending lots of time doing it and learning a little along the way.

For all your attacks on the presenter, your argument of a bi-modal distribution sounds more flawed to me. I would love to see your study and hear your argument.
