Information is not physical property. Otherwise you could call up an old sys admin 5 years from now and ask him how he solved a problem. It's information he gained on the job, and he still has it so clearly he needs to go to jail if he does not tell you how to fix the problem.
Precise layout is a sign of poor webpage design.
HTML was designed so the clent decides how to present information to the user. A good HTML desgin can work well on an iPhone or 30" monitor at the same time.
You could build a 99% efficient regenerative breaking system. Now it's true that thermodynamics limits will eventually come into play, but once you stop dealing with heat engines thermodynamics becomes far more gentile.
vast majority of art and culture we produce a tiny fraction of the worlds art and culture. However, as you only speak one language out of thousands are obviously stupid it's easy for you to forget that simple fact.
They are assuming 4.5% efficiency and electricity as a 1:1 replacement for all energy needless to say their numbers are totally wacked. Average power per square meter is around 1000W * 8 hours / 24hours a day * % efficiency. So at 10% you get 33W/M not 15 but we already have 30% efferent solar cells. Beyond that using sunlight to generate electricity to heat water is stupid. Directly generating hot water from sunlight produces an average power output of around 300W/M which is 20 times higher than their estimate. Toss in some wind turbines and the amount of land required continues to drop.
Also electric cars require far less energy than gas cars so that 15TW figure is going to drop even more.
PS: The world's total supply of energy extractable from fossil fuels (Oil + Coal + Natural Gas) is less than the amount of energy extractable from renewable sources in one year. (http://en.wikipedia.org/wiki/World_energy_resources_and_consumption)
Wait, 2^64 = 18,446,744,073,709,551,616 bits, but only 2,305,843,009,213,693,952 bytes. Anyway someone is going to want 2,097,152 terabytes of RAM before too long so I expect MS needs to look at 128bit systems before long.
PS: It's only 2exabytes, start to dream.
Don't worry, they might make the stuff chemically inert, but it's still radioactive.
That's overkill for 17 years. Just use a few USB sticks. Interfaces tend to stay backward compatable for a long time. So finding a 5 year old computer that supports a 12 year old standard in 2026 should be easy.
The cost benefit curve in the consumer CPU space is strange. A 10% faster might be worth twice as much or be totally useless.
EX: Real time playback of HD movies. If your CPU can't do that it's a pain. However, if it can then extra speed is pointless for that task.
To increase profit. The goal is to maximize (unit's sold * profit per unit) not just (unit's sold) or (profit per unit).
In theory if you lower the price you can attract more customers. This is offset by a loss in profit per customer. In the real world not everyone is willing to pay the same price. You see this most clearly with coupons. People who are not willing to use coupons are charged more because not as price sensitive. EX: I could not care less if my lettuce cost's 10% more so they charge me 10% more.
FYI: Military spending on fuel is negligible in comparison to manpower.
The link said the Air Force uses 1/2 the fuel of our armed forces, which is probably also waked as the Army has more airplanes than the air force.
PS: Oil costs less than 5% of our GDP. We use lot's of oil because it's cheep but there are lot's of options including turning coal into gas.
