In the USA, Toyota has these SUVs: RAV4, Highlander, 4Runner, FJ, Sequoia, and Land Cruiser. Last I could count, that's 6. Do you want to throw in the Scion xB? 7. The car tally: Yaris, Corolla, Matrix, Camry, Solara, Avalon, Prius. 6 to 7. If you add in the Scions, xD and tC, the tally is 7 to 9.
Charging batteries produces waste heat. Discharging batteries produces waste heat (remember the laptop battery getting hot enough to start a fire? Waste heat.) And the electricity has to come from somewhere.
Compare the total energy cycles:
Sunlight -> plants -> cellulose ->(bacterial fermentation in this step)-> hydrogen -> fuel cell -> electricity -> vehicle motion
The 70% efficiency of the fuel cell and the 70% efficiency of the fermentation production of hydrogen, together (49% efficiency) is still better than the 40% efficiency of the coal->electricity step. And doesn't produce any greenhouse net gasses. And is completely renewable.
If you really care, you put magnetic switches on the equipment. Normally off. When you press the "on" button, it energizes a relay that sends power to the switched device. The relay only stays in that position while there is mains power. When you press the "off" button, that current is interrupted and the relay opens. When the mains lose power, the current holding the relay closed is interrupted and the relay opens. So that when power is restored, the device is off.
Ahh, but going to smaller features means, and shorter distances between gates, also means that the lines become narrower. Resistance is proportional to length, and inversely proportional to cross-sectional area. So if you halve the length, and halve the area, total resistance stays the same. Basic EE, folks.
Smaller might not mean less resistance, unless the lines get shorter faster than they get narrower.
Rather than old-fashioned reciprocating engines, how about outside-of-the-box thinking? A small gas-turbine, powering a generator, battery packs, and then electric motors driving all 4 wheels and offering regenerative braking as well?
Hydrogen power is best when it doesn't suffer the 40% losses of combustion, i.e. when it goes through a fuel cell and is converted to electricity with 85% efficiency.
IA32 is going the way of the passenger pigeon. There may be a few rapidly diminishing flocks left in the wild, but they'll be gone in a blink of the (metaphorical) eye.
AMD-64 for evah! (or at least, the next decade). Oh, that's also spelled "Core 2"...
Another factor that assimilates immigrants into the USA is the fact that anyone who is born here is automatically a citizen. Not so in some other countries. They have 3rd and even 4th generation "guest workers" who do not have the same rights as those born into the dominant cultural community.
I encounter an awful lot of products that are labeled in English and French. That is not because of unprecedented levels of illegal immigration from France. The vendor wanted one product that could be stocked on store shelves anywhere in North America, and in Quebec, they speak French.
Could vendors be packaging their products for both US and Mexico?
Come on. Questioned, and told that if he doesn't confess, he will be sent to Egypt or Syria where they torture terror "suspects" because we ask them to. This isn't fiction, it has happened.
Right. "Islamic" is an adjective, and is used to describe things that are associated with Islam. "Muslim" is a noun, and refers to a person who follows Islam.
Neither of which are the adjective used in the original post: "Islamist". That refers to the political movement to institute government according to Islamic principals.
one thing this court is known for is pushing federalism
Oh, yeah, like the part where the constitution says that states get to run elections by their own rules, and then decided that Florida couldn't do a recount according to their own rules...
I don't buy this argument for a minute (that medical companies aren't trying to cure diseases, because it costs them customers). Look at all the childhood illnesses that used to claim thousands of lives a year: Polio, Measles, Mumps, Rubella, even Chicken Pox. All effectively prevented with vaccines. Prevention is even better than a cure.
Look at Tuberculosis. It used to be incurable, fatal, and contagious. Then we had a long period where the disease was curable with antibiotics. Then the d*mn bacteria evolved resistance to antibiotics. Partly due to stupidity on our part, and partly because that's what living populations do.
We've gotten the "easy to cure" diseases. What's left is the hard to cure ones. Is it surprising that they're hard to cure? Or affect fewer resources, and get less attention.
It's hard to write software that always works on multiple platforms. Guess what? Genetically, we're all a little bit different. Developmentally, we're all a little bit different. It's hard to come up with a cure that works reliably in everybody (or at least, we can reliably figure out whether a treatment is appropriate for a given patient).
A long time ago, Stereo Review (remember them?) brought in a panel of "Golden Eared" audiophiles to listen to the sound of a pair of Conrad-Johnson monoblock amplifiers. They loved it. They listened to a $200 Pioneer receiver. They hated it. Then they hooked them both up to an A/B/X comparator system, and asked them to tell which was which. They couldn't do better than chance. So what people claim they can perceive and what people can perceive in test circumstances is different.
A $2,000 speaker setup will sound better than (and likely take up a lot more room than) a $200 speaker setup. And if you have an auditorium-sized listening room, you need a lot more power than Best Buy quality gear. But the $800 "Home Theater in a Box" setups are selling pretty well.
My "Home Theater" receiver died two years ago in a thunderstorm. Lightning strike across the street. Fried the cable modem, the router that the cable modem was plugged into, and every ethernet port plugged into the router. Fried the modem on the TiVo, and for some reason, one side of the output stages on my receiver (that was off at the time). I haven't replaced it. Priorities change over time.
This very essentials of digital computing created the definition of kB, MB, GB, TB etc
No, essentials of digital computing created the usefulness of binary-based units. The definitions of k, M, G, and T were established long before digital computing (digital? Base 10? Really?) came on the scene.
And the standards bodies have agreed on units for the digital computing information storage needs. Yet the lawyers in this case have convinced a company that it would be less expensive to fork over payola than it would be to maintain that they are correct the prefixes in the way they have been used for centuries.
Hard Disk Manufacturers are using the standard definition of kilo, mega, and giga, and their standard abbreviations k, M, and G that have been in use for over 2 centuries, and are used that way to measure many different things (kilogram, kilometer, megahertz, gigahertz).
It is the operating systems vendors who decided to use kilo, mega, and giga in non-standard ways to mean 2^10, 2^20, and 2^30.
If I order 10 tons of grain, can I sue after delivery if I was only given 9.07 metric tons? And add fraud charges on top? Especially if the contract (the package of the hard drive) says that GB means 10^9 bytes, and ton means US ton?
Every time I've returned something, the store asked for a name, address and phone number.
If you "make it a habit to scam them", they notice on the second or third return, and turn you over to the police.
But on a customer's first return of something like this, the store really has to accept it. The store, and the chain, is risking a significant PR backlash giving the guy a hard time.
My local Best Buy has done all right with me, though. Better than the Circuit City just across the road...
No, the young can hear up to about 18 to 20 kHz. Sensitivity to high frequencies rolls off as you age, and as you expose your ears to loud (as in ringing in your ears afterward loud) sound.
Most CRT NTSC TVs emitted a piercing 15 kHz scream. While I was in college, I could hear if a TV is on in a dorm room, even if it was muted, because I could hear the scream. It was loud enough to be obnoxious from every TV I encountered. 20 years on, I can't hear it any more. One of the benefits of aging, I guess.
Having a President, and a press corps, who had basic knowledge of Economics would be a good start. And elementary arithmatic. 1 + 1 + 1 is greater than 2, yet the voices that publically called Bush on his tax cut plan in 2000 were strangely mute. Now America owes about a trillion dollars more than we would have otherwise.
Of course, it wasn't the FBI or the CIA who said "You've covered your Ass now" and proceeded to ignore the warning that was just received. It wasn't the FBI or the CIA who were contemptuous of warnings from the chief counter-terrorism advisor.

I want to build a home file server that I can run and not feel guilty about wasting power. Can you share details?

The General Purpose CPU was invented back in the 1950s.
It was reduced to a single piece of silicon back in the 1970s.

It's more like being sold a car with a 40 US Quart gas tank, and then discovering that it only holds 37.8 Liters.
Go see "Into the Wild". The Wild kills.

The claim that most can hear 18 kHz is nonsense.
And vinyl, with it's 66 dB dynamic range, needs MORE compression, not less, than the 96 dB dynamic range of CD.
