    These brown sites will by nature of them be farther way from existing infrastructure resulting in higher costs to send both materials and labor to the location.

    Precisely the opposite. If you RTFM, you'll see that the listed benefits include: power transmission lines are often already available on site (leftover from the site's previous use), and the sites are often located in areas with depressed economies (read: readily available labor from nearby towns, that used to be employed by the old site)

    Also there will need to be extra safety precatuions taken for the labourers and the waste from the zones.

    I think they are limiting their scope to sites where the pollution has been cleaned up to minimally acceptable levels.

    The fact that [Time Machine] requires a separate drive is something of a joke

    It actually doesn't require a second drive... you can have it back to up another partition on the same drive. It will warn you that you're about to do something stupid, but it will let you do it if you really want to.

    I trust that it's clear why backing up your data to another partition on the same drive is generally a dumb thing to do.

    Second, Time Machine is always scanning my drive checking if it needs to back things up. I'd really like it to try to scan for silent corruption while doing that. If a file changed, but the fileystem data says it hasn't been modified... I'd like a way to see that or be warned.

    According to an article I read (that I can no longer find on line :^( ), Time Machine works by having a daemon that runs continuously and is notified whenever a file is created or written to. That daemon merely maintains the set of "dirty files" in the file system; when it comes time for Time Machine to do its thing, Time Machine grabs the dirty-files-set from the daemon and copies just those files over to the backup, then tells the daemon to clear its list of dirty files.

    So Time Machine isn't actually "scanning your drive", it's just copying a list of known-changed files over. Presumably if they were to add scanning for drive corruption, it would make things much slower than they are now.

    Crash all you want, but never, ever, ever harm, corrupt and by all that's holy, NEVER delete the user's data.

    Except that if you are going to guarantee that you'll never corrupt or delete the user's data, then you have to guarantee that your program's behavior is well-defined. And usually programs that crash are crashing because they contain errors that lead to undefined behavior.

    So if you want to be sure not to corrupt anything, you pretty much aren't allowed to crash either. (note: even if your program never writes to the disk, if it's buggy it might be vulnerable to a code injection attack that would cause it to write to the disk...)

  5. Re:Computational Problem on The Problem of Shards, Servers, and Queues In MMOs · · Score: 2, Interesting

    The fundamental design flaw they all have is that servers represent space in the game, it's a flawed assumption about the best model to use.

    I'm probably just being naive here, but isn't the flaw really that the servers represent a fixed amount of space in the game, while at the same time the amount ("density") of user activity in a given space can vary, and therefore the amount of processing and I/O needed to support that space can become more than the server can support?

    If so, perhaps a solution would be to make the server's "game-space-allocation" variable... i.e. if a server gets too busy, it allocates another server (from Amazon's E3 cloud or wherever) and transfer half of its game-space (and therefore half of its load) over to the new server. Conversely, if a server becomes underutililized it could merge itself back together with another underutilized server to cut costs.

    Of course that would still leave unsolved the problem of seamless interactions across neighboring servers, but it's Sunday so I'm not going to think about that.

    Patents are something that shouldn't exist in the first place!

    Without patents, there is a huge incentive to keep all commercializable discoveries and inventions secret, because that's the only way to prevent your competition from selling the product you invented more cheaply than you can (after all, you have to repay all the debts you incurred while inventing/perfecting your invention, and your competitors don't... all they have to do is obtain one unit and then duplicate it).

    With patents, you are granted a temporary monopoly on your invention, and in return you publish the invention in the public record. After 14 years, the patent period ends, and now anyone can use your idea for free, forever.

    In my opinion that's a better result than having the invention remain secret forever.... YMMV.

    Actually, a nice technique would be simply pump out the spent (liquid) contents of the car's battery, and then pump in fresh, charged contents from the gas station's reserve. That would avoid the mechanical complexity of robotic battery changers, and reduce the "recharge" time down to less than that of gas-powered cars. The station could then recharge the recovered contents at its leisure.

    Okay, Mr. Economist, take your speculation forward another step. What will happen when electricity prices rise? Yes, that's right, there will be a great financial incentive to increase production of electricity. And unlike gasoline, whose supply is finite and dwindling, it's perfectly possible to produce more electricity in a number of ways. There are already companies that will install solar panels on your roof on their dime, in return for a share of the energy the solar panels produce... it's likely that in the next 10-20 years these same companies will actually pay you for the privilege of installing solar panels on your roof, because they will be able to sell the resulting power at a profit to electric car owners. Then there's wind, nuclear, tidal, geothermal, solar thermal, etc.

    In short, it's the supply of fossil fuels that we should be worried about, not the supply of electrons.

    If it takes an hour to charge, it better cost far, far less than gasoline.

    If they can extend the range to be long enough that it can drive for an entire day on a single charge (admittedly a big if), then suddenly the recharge time doesn't matter as much. After all, you're going to have to stop off and sleep for the night, and you can leave the car plugged in to recharge for 8 hours while you sleep.

    .... and of course when gasoline costs $10 a gallon, it's not so hard for electric power to be far, far cheaper.
