The biggest energy demand in a house, air conditioning (fully air-conditioned, not just one room), any idea at all how many HP (horse power for slow Americans, rather than kW) a large domestic air conditioning unit is (single digits) and now compare that to the HP of car (triple digit). So power to spare in some locations, not all (yep, snow is a real problem). So for most locations no if and you choose whether or not to take the risks but when others don't that energy insurance will get expensive (likely over the long term cheaper to buy a second smaller stand by battery for lighting). Flip side of course brown outs or black outs of mains, no longer a problem, this will get much worse over time, as they take more short cuts to maintain profit with reduced revenue, especially maintenance and customer support short cuts.

Face, the target should be thankful, that a major corporate political player is not claiming the defendant murdered the data and should be executed. Clearly they feel infringed upon and are using their control of the US department of in-Justice to persecute the individual. I am surprised they did not go the espionage route if the code just appears in another country.

Cough, cough, IBM did the work, M$ just ran off with the benefits due to a very, very shonky contract. IBM could have still wiped M$ out if they had not been stupidly greedy when they released their own much better OS. Lotus blew it by not reducing prices to compete, same with Word Perfect. Xerox also gave away ideas for free. So rather than M$ success it was others failures. So luck and yeah corruption with regard to corporate lawyers had a lot to do with.

Cheaper to live there brings to the fore, desirability of location to attract employees (cheaper to live there not so much, as cheaper to live means it likely sucks, supply and demand you know). So can companies attract better people and at lower costs by providing a better live, work and play environment, not only within their facilities but in the community at large. So locating according to this, likely makes the most sense if you want to attract and keep the best people. Ain't the bosses that make companies (time to drop the main stream media celebrity illusion), it's the workers (that is the reality).

Note, one huge advantage with locating at the best locations away from major competitors, it makes it much harder for staff (and their families) to leave to go to those competitors especially if those competitors are in cheap ass undesirable locations in the middle of a desert (you'll keep the most long term productive and lose the greediest often medium term destructive).

So pick a city from the lists, check regional language use, check for competitors and, then check costs. Equipment can go anyone, good staff will be much more choosy and where does count a lot for them. Give the staff good quality of life and they are unlikely to leave to go to a competitor at a worse location, you might still lose them to local industry at that location but at least they will not be going to major competitors. Don't forget things like universal health care (means you don't have to pay for it and can discount their wages because they don't have to pay for it either). Climate, beaches, parks, recreation, choice of schools etc. (smaller capital cities will generally work best).

Time will alter everything. Reality is, the more batteries produced the cheaper they will become and much more interestingly, the more batteries installed, the fewer people paying for electrical mains infrastructure, the much more expensive per user it becomes. That economic boulder rolling down a hill, faster and faster and faster, inevitable. Tesla still needs to do a complete system, ready to install by franchised installers (ensure quality installs), keep it simple. Not to forget, the Tesla power pack would be a strictly utility device, much like adding air conditioning, or a verandah, it adds capital value to the property. So forget the incumbent PR=B$ about measuring it against electricity charges because that is only part of it's value, it has real capital asset value and that value also needs to be added in, to more effectively compare it what is in affect rent and burn (rent your part of the infrastructure and burn your capital inputs).

Who cares about the emotive content of the image. That makes absolutely no sense at all. Why isn't a more effective image sought, one that will more effectively test video compression techniques, specifically to make flaws more visible, in pattern and colour transitions. Holding to that image is a stupid as holding to QWERTY keyboards.

Hopefully this is a sign the space race is back on. Far more to do out there, then to squabble back here with, who can destroy the world the most number of times with their military, a real dead end and I mean dead end. Something is needed to drive humanity, to focus it's efforts and who is the greediest and most selfish or who can kill the most, are insanely, stupendously pointless and self destructive of society.

Making use of the resources of the solar system, is not about bringing stuff back to earth, it is about humanity expanding it's horizons further out. The difference between dwelling upon your genitals (hollywood et al) or dwelling upon your mind (NASA et al).

Upfront cost? Most engines are charging percentages of revenue which means they can quite readily chew up 100% of the profits ie if your margins are only 10%, then 5% of revenue means they will be demanding 50% of your profits. How can programmers be so bad at math. If anything the crytek models looks suspiciously cheap. Can a programming house with 100 programmers get one subscription or do they need 100. How far out into the future will the subscription and its conditions hold, ie at least 3 years and preferably ten years but the customer can drop it at any time.

The current percentage of revenue model is nuts and should only be around .1% not 5%. Imagine M$ bringing in that model on spread sheet software, we demand 5% of your revenue if you want to use our software.

Kind of late for that mate, it is already happening and unless you intend to pass on shortly you will be a part of it getting much worse, good luck, you'll need it in America. Emigrate early, rather than late because whilst the asshats that caused it all the 1%, most certainly will make sure they can leave with a substantive portion of their wealth intact, their victims the 99% not so much. Collapsing Empire's trying to force the continuance of their waning dominance, inevitably become self destructive. The US is becoming such a laughable example of this it will simply be easier to refer to them as characters out of star wars, the evil empire, the president as Emperor and his Darth as vice president and futile and corrupt congress and senate and of course the US military, the storm troopers, "the tighter you squeeze the more they will slip through you fingers".

'ER' Dude you are electing a representative president that is meant to implement and administer the laws provide by the senate and the congress, not fucking god. What the fuck are you talking about except typical PR=B$ hyperbole ad hominem attacks. Yeah sure, a bunch of very corrupt rich exploiting the poor laws need to change in order to rebuild the core, the middle class, but all the president can do is implement the policies provided and either do that well or do it incompetently or do it some what competently but extremely poorly because actions where based upon very unsound and corrupted information designed not to provide solutions but feed insatiable vested interests (corrupt advisers produce corrupted outcomes).

Easiest hypothesis to explain the reaction, a teeny tiny undiscovered particle, likely it would explain a lot of other things as well. So the real question is, could a particle be small enough that it is impossible to directly observe outside of it's interactions with other particles. It is there because we can observe the outcomes of interactions but it is not there because it is simply too small to directly observe. Those interactions would likely be indirect field actions rather than direct actions. The measure of the engine less likely to be concentrated power output but how large an interaction the engine can produce, an engine that operates more outside of itself rather than within itself.

How about this reference, yet they still train psychologists to work in marketing targeting children. Did the American Psychological Association, play with the torturers and in the most sick fashion imaginable the victims? Was there a buck in it? You betcha, it's the American way, your American dream and fuck their nightmares.

So which is worse damaging the psychology of children to sell products or participating in the psychological torture of suspected terrorists, pretty fucking much, equally evil. Unless of course those suspected terrorist are also minors, yes, the US military managed to achieve that level of evil, with the aid of professional psychologists. Well, at least Darth Cheney managed to truly earn his spot in history and so did Uncle Tom Obama for failing to prosecute.

The catch with the whole idea is they are just forecasts based upon limited range of scientific theories and do not take into account everything that could happen. For example major steps could be taken to reduce solar inputs, only to be followed by a significant impact that throws a lot of dust into the atmosphere and now the opposite is the problem. A major solar flare could also cause significant environmental impact, that could again compound any active attempts at cooling the atmosphere.

The only sound method of control is to stop doing things that could cause problems, rather than take risky actions that could be negated or have far more impact than expected because of unexpected climatological inputs, even a major volcanoes could cause severe problems if it occurs in conjunction with major attempts at active cooling of the planet.

Scientific theories explain would should happen under a very set specific range of circumstances and are not a crystal ball of what will happen at some point in the future taking into account, everything that could happen to the sun, earth's geology and all possible astronomical events. So the idea is to use scientific theories to reduce risks on this planet and not to increase them.
