That isn't how wear leveling algorithm work. Yes, once you hit 99%, every write does involve a rewrite somewhere, but those writes are not concentrated in the 1% free area. Instead, the drive controller is reading sections of already written disk and moving them around.

"Well, you seem to be using a different definition of meritocracy from everyone else. But OK, let's use your definition."

I'm using the dictionary definition, if you have a problem with that then don't take it up with me, take it up with the whole of the rest of the world who you seem intent on rallying against.

"Well, by your definition then the Linux dev community is not a meritocracy because the asshole element is causing some of the best people to leave, lowering the overall quality of the contributors."

That's probably quite true. I can think of some examples where you're absolutely right, but I'm really not interested in flying off on a tangent and arguing about drama in the open source world. That doesn't mean that merit doesn't count for anything, of course it does, but it's certainly not the whole picture there.

"Your definition seems to be a rather holostic thing where people are promoted on merit as defined by something that optimizes the performance criteria you're interested in. That's OK, an by that definition, then yeah sure you can have a meritocracy. It's just a different definition from the one everyone else seems to use."

I don't know who this everyone else you talk of is, everyone else is typically content with the dictionary definition which defines a meritocracy as the holding of power by those with the most merit to complete the task at hand, and in business that means those most able to fulfil the business needs, such as figuring out how to can the most tuna.

You're on one hand asserting that a meritocracy can only determine merit on one single thing - in your example, technical capability - and yet, you're then judging that meritocracy on things that are outside it's definition of merit. This is entirely nonsensical.

If you feel that niceness to team members is an important merit in your meritocracy then you must also include that in your judgement of merit. Thus someone with high technical skill but beats other members of the team up would end up with low merit.

The problem is not that a meritocracy cannot exist, the problem is that you do not understand what a meritocracy is - you're arguing that a meritocracy can only judge merit on one single trait, and this is patently untrue. You have effectively taken the GP's mistake of suggesting only technical merit is necessary and then expanded it to imply that this is true for all meritocracies and therefore meritocracies cannot exist.

A simple example is imagine I run a tuna canning factory, and all the workers sit such that they can't interfere with each other, but one worker consistently cans double the amount of tuna in a day than any of the others with no reduction in quality or other detriment to the company. I promote him because he's figured out a way to be more efficient than everyone else. That is a meritocracy.

Feel free to argue why you don't like meritocracies, or why you think they're bad (i.e. you may want to argue that they're not fair on people who only have one arm so can never can as much tuna even if those people try way harder and put more hours in), but pretending they cannot exist based on a nonsensical argument following on from an argument you're complaining about yourself doesn't make a whole lot of sense.

The Thunderbird was nice, but it was more of a price/performance winner than overall performance. A 1GHz Thunderbird ran stable at 1.3GHz and was similar performance to a 2GHz Pentium 4 at a fraction of the cost (particularly as the P4 required RAMBUS DRAM, so you could stick twice as much DDR in Athlon for the same money). It wasn't until the Opteron that AMD really started winning on performance. The integrated DRAM controller was a big win and being first to 64 bits (which, on x86, means more GPRs, sane floating point ISA, and PC-relative addressing) gave them a huge advantage. Unfortunately, they haven't really been competitive since the Core 2, except in market segments where Intel intentionally cripples their offerings (e.g. no more than 2 SATA ports on the Atom Mini-ITX boards to avoid competition with the i3 boards, making AMD the only viable option).

Japan has been xenophobic from the start, they are much farther along in demographic decline, they are doing fine.

Only if by "doing fine" we ignore Japan's massive debts. They have a higher public debt per GDP than anyone else, including such outstanding examples as Zimbabwe or Greece.

Thanks, I was crunching the numbers in my head, and I was heading to the same conclusion you detailed.

That said, I think batteries become viable, if not today, maybe soon:

[...] a research team at the University of Tokyo School of Engineering has announced a new lithium ion battery [...] energy density â" at 2,570 watt-hours per kilogram [...]

This is a couple years old...but its clear the tech is moving forward.

Obviously stability/reliability, production scalability, and cost are all obstacles. But 2570 w-h/kg is almost 10MJ/kg which changes the viability substantially.

Your point about jet fuel expenditure being front loaded on the trip ... I read somewhere that the most fuel efficient flight for a jet is around 4300 miles. It seems that an alternate fuel for short hops could make sense.

Fossil fuels are great, and there's no reason to stop using them anytime soon; I am not anti fossil fuels.

But unless we find a way of producing it cheaply we do need to move on eventually. Growing crops to turn into fuel, it amounts to an *extremely* inefficient solar solution (months of solar collected in the form of plant biomass) which then has to be processed into fuel... better perhaps to take those fields grow food in them, and throw up panels in the deserts to charge batteries.

As for your comments about the charging issues, I imagine a battery swap solution being viable for fleets of aircraft.

For a typical airplane, though, increasing the weight of the energy source by 10x guarantees that it will never leave the ground: at take-off the jet fuel powered version is already 25-60% fuel by mass; increasing this by 10x would increase the total mass of the plane by 3-6x.

Does hold that true even for short hops? Paris to Madrid? London to Frankfurt? LA to Vegas? Sydney to Melbourne?

Sure a plane with an 8000 NM range is 50%+ fuel by weight... but most european continental flights are under 500 miles.

There is that - then there are people who sell fried pork doner kebabs as if they are a middle eastern food (ironically the place near my work that does that is run by Chinese - hence fried instead of grilled and pork instead of beef or lamb).

It appears the hot dog analogy didn't work, or was it just left unread before the reply?

I suspect if something is different enough to stir up protests we are in pork chop in synagogue territory. Either way I really can't see how DarkOx can use it to support an SJW strawman.
