Already done. There's a prefix reserved for "4in6" addressing: you drop your IPv4 address in behind it and you have an IPv6 address. That isn't the hard part; the hard part is getting router manufacturers to do the firmware changes needed for 4in6 routing policies and the ISPs to buy the firmware upgrades. I'd guess that the router builders are about done and it's the ISPs who need prodding.
*sigh* I've had my pppd asking the ISP for an IPv6 address for a couple of years now, just in case, but so far they're not interested.
I suppose there was also some thought about (a) what it would cost over the interval to *not* transition to IPv6 (for example, techie hours spent figuring out how to do things that IPv6 would take care of for us) and (b) how much of that transition is going to happen over the interval anyway, due to attrition and to economies of scale from replacing entire infrastructures rather than maintaining a mixture of old and new products.
Does it? Take a volume of H2 and an appropriate volume of O2 at STP. Burn. What's the volume of the resulting H2O at standard pressure and *flame temperature*?
Um, first figure up the mass of the core. Now calculate (a) the amount of heat you can extract to bring it down to the freezing point; (b) the amount of additional heat due to continuing radioactive breakdown that you'll also have to draw down continually to get to freezing; (c) the even more enormous amount of heat you'll have to draw out to cross the phase line. Then come back and tell us how many millennia it will take to use up all that heat without utterly wrecking the atmosphere. We'll either be gone or capable of interstellar migration by the time that happens.
Humph, that might be more energy than we'd need to *do* the interstellar migration.
Concentrated hydrochloric acid is natural: your stomach makes some every minute. Uranium is natural: it's dug out of the ground like coal (also natural). Horrific, destroy-all-in-its-path wildfires covering thousands of square km. are natural and have been happening since long before humans came along. Just because it's "natural" doesn't mean it's nice.
Geothermal hot spots will be cooled, not eventually, but *immediately*. By a few degrees within centimeters of the tap, millidegrees further out. Meanwhile more energy flows in from elsewhere. Moderate extraction will simply set a new equilibrium point somewhat lower than the old one but will still provide plenty of energy, and energy flow into the affected area actually increases a bit since the potential difference has increased.
Meanwhile, yes, Australia should indeed develop its solar and wind resources *too*. Some companies invest in one, some in another, and society reaps the benefits of all of them.
Remember that the extracted heat *itself* can be looked upon as a pollutant, and by extracting it we're increasing the rate of pollution and moving another equilibrium point. One of the (possibly still distant) restraints on growth of a high-tech society is simply the ability to get rid of waste heat without moving an equilibrium point that's too touchy for comfort. And one of the laws of thermodynamics boils down to the principle that all energy eventually becomes waste heat, so the overall density of energy use should be considered carefully.
So you believe that winged monkeys really *do* fly out of people's backsides from time to time? Look up "figurative language" -- it could change your life!
Anyway, on email the closest you can get to derisive laughter is "/\/\/\/\/\/\". Oh, the cruelty!
The best thing that could happen to mankind is the stifling of certain new features and improvements. My modal reaction to "upgrades" from certain other software suppliers is, "how do I disable that?"
Anyway if you miss the window for kernel J.K.L there's always J.K.L+1 coming along. Meanwhile people with a burning desire for your patch can get it from you. It's annoying, but the person you should be annoyed with lives in your mirror.
I know, but since it won't cross my router I don't much care. By the time they agree on a specification for what these *can* be used for, get all the old uses cleaned out, see some new books published, and actually roll out the new use, that toaster'll be in a landfill and my children can set the new one up differently.
I may review this attitude if my ISP ever puts down the stone knives and bearskins long enough to turn on IPv6 on their gear. If they'd allocate me a routable prefix I wouldn't have much use for site-locals.
I didn't say how they should fund the decision to make things right. Asking the guys who made the decision to do things wrong to pay for cleaning up the mess sounds right to me. If Sony's like most corporations these days, one year of executives' bonuses would pay for a massive recall with money left over for the going-away party. They can sue the guys who actually made the ill-specified DRM "solution" to recover some of the cost, too.
Is there an echo in here? "We'll never run out of [2^N for any value of N] addresses". Yes we will. There are people who are scheming to put every bloody light switch and kitchen appliance on the Internet. There are people designing applications to run on microscopic hosts that will be scattered like seeds, by the thousands or millions.
It's 128 bits instead of 64 so we don't have to go through this again in five years.
Remember, the Internet *core* used to run over 56kb/s lines -- the same speed as those $20 modems that individuals are throwing away by the basketful today because they're unbearably slow for *personal* use. It's *hard* to plan well for that kind of growth. Better to waste a couple of bits than have to waste the whole thing and do it over.
I absolutely loathe sites that automatically store my CC number "for your convenience". It's mighty INconvenient to have to go back and edit the card out of my account every time I place an order. I tend not to go back to such vendors.
A much bigger win is providing the simple "yes, like 99.99999% of your customers, my billing and shipping addresses are identical" checkbox. Remembering that 1-bit datum as part of my account would be even better.
They really shouldn't store the card number at all. The card issuer should take the card number and amount, and return a one-time transaction number, which is all the vendor need store in order to look up the transaction with the card issuer should that ever be necessary.
Think for a moment. *UPCs* are nonunique, but barcode can encode anything you like. Some cartons drive me crazy trying to figure out which of the dozen barcode blocks is the UPC. I've received shipping cartons with different barcoded data on all six faces -- some from the manufacturer, some from the vendor, some from the shipper.
Some stores won't wait for government, uh, requests. See paranoia threads on data mining. Marketing people think they can analyze my purchases and influence future decisions. (Good luck to them...when I go into a store I already know the make and model and the price I expect, and if you don't got that one on the shelf at around that price then I walk out emptyhanded.:-P )

Whale oil! Save the whales, we need the lubricants. :-)

Will it affect the ground in *any way*? Sure. Will it affect the ground in any *significant* way? I seriously doubt it.
Of course fans of Samurai Cat know that Delaware is everywhere. :-)
It sounds like a wonderful place to live, then.
Yeah, you probably get sunshine in MN in January and February. IN doesn't. :-(

That's just Linus. I'd take it as a means of emphasis, not a personal attack.
Besides, if I ignore The Rules I *deserve* to be laughed at.

"So how do you put a corporation in jail?"
Revoke their import/export licenses.
Stop the trading of their securities.
Lots of other ways. You need all kinds of permissions to do big business. Those permissions can be withdrawn.
No, Sony should replace every one of their malware disks with a genuine CDDA.
Nobody wants IPv6 because it isn't turned on automatically in Windows. I hear that the next iteration is supposed to fix that.
Meanwhile I have it running in my home and at my office. Works great. Easy to set up once you wrap your head around it. Try it and see.
Put your toaster on fec0::/10 and it won't be routable. There you go: secure.
