  1. Re:How long does it last? on Electric Car Goes 375 Miles On One 6-Minute Charge · · Score: 2, Informative

    It is quite trivial actually, the lithium isn't consumed, deposits develop and the (cheap) electrolytes degrade, it is a simple (relatively) chemical/mechanical process to clean the lithium and rebuild the cell. Not something you do in place, but every 5 years or so you get your battery exchanged. Less work than replacing your tires or shocks. And since you arn't buying any more expensive lithium, it probably won't be that much. Lithium is certainly a fully recyclable resource. And it is a whole lot cheaper than the Palladium that is the best bet for hydrogen storage at the moment.

    Failure to show up is a vote of *confidence* in the system. The US voter turnouts are so low because for the most part, US citizens are happy, or at least, not unhappy enough to give up an afternoon to change it. The places where they have 99% voter turnout are the ones in civil turmoil or just not good places to live, people want to change it.

    I think all laws should not just have a sunset provision, but a testable intended effect when possible. For instance, a law requiring seatbelts would have an intended effect of "reduce fatalities due to car accidents." then when the sunset comes up, reasonably good evidence that the law is having the original intended effect must be presented.

    I don't think this is unfair against law abiding citizens, it is simply unfair to people unwilling to do the slight amount of research and mild effort required to find the answer to their question. Like one phone call to the court, or a google search. I think you will find that people unwilling to do that are at a disadvantage in many areas of life, legal or otherwise.

  6. Re:CISC to save RAM? on IBM Unveils Fastest Microprocessor Ever · · Score: 1

    Actually, CISC uses less memory in general, but has traditionally been slower. CISC CPUs came out when memory was extremely expensive relative to CPU speed. cheaper memory is what made RISC (with its larger footprint but faster speed) possible. Nowadays, it really doesn't matter much, CISC is probably better nowadays that memory bandwidth is the big bottleneck. However, our CISC designs are not exactly modern, if you were to do a modern CISC design you would probably end up with something more akin to ARM's thumb instruction set.

    All in all, x86 didn't end up too horribly off, its plethora of addressing modes actually makes smaller code on 64 bit systems because integer arithmetic can be 32 bits by default as you rarely need to directly operate on 64 bit values in arbitrarry ways as the addressing modes can perform most pointer arithmetic that is needed. Matching the 32 bit 'int' and 64 bit pointer on x86-64. Not that there arn't issues with x86, but being CISC in and of itself isn't one of them.

  7. Re:Well... on India Now Wants Access To Google and Skype · · Score: 1

    The only way to change that is to change the economic equation. Stop shopping at walmart. Refuse to buy products from companies not producing here in the US (good luck with that). Refuse to sign up for internet if the company outsources its call center, and be sure to let the CEO know why you refuse to buy. Start a campaign at your employer to buy American.

    There is a much better way to change it. Bring the economic situation in india up to par with the united states so wage and quality of life improvements there make outsourcing less attractive. A difficult problem, but probably more tractable than changing the way every american chooses how to shop and it would leave the world in a much better state overall.

    If anything, they are optimizing their games to get people to sign up and pay the monthly fee, but load their servers at little as possible by playing few hours. that maximizes their reward. If they make content that could potentially take 11 hours a day every day, it is because there is demand for that, some people want that out of their monthly fee, I am sure the companies would rather have people pay the fee and never log in but tell their friends how great it is.

    In truth, it does always bother me how easy it seems to 'blow up' planets in fiction. If you think about it, the amount of energy required to blow up a planet would be equivalant to launching every bit of the earth into space, think about the amount of energy involved in just getting the tiny space shuttle into space, then think about doing that for mount everest, then think about doing that for mount everest about 10,000,000,000,000,000,000 times. That is how hard it is to blow up a planet (very roughly)

  11. Re:I'll wave when I drive past you ... on Company Builds Fast Charging Station For Electric Cars · · Score: 2, Insightful

    The way to make a hydrogen car viable is to take your nth generation series hybrid car and replace the engine/generator with a hydrogen fuel cell. Once you are mainly using electricity off the grid, you only need to refill your gas tank occasionally, since you are only doing it every now and again, going to a hydrogen dispensary is less of an issue, even if there isn't one right around the corner. As hydrogen/electric cars become more palatable, hydrogen fuelling plants become more common, eventually you don't need as big of a battery to get between them.

    A migration path is key. series hybrid cars let companies experiment with different supplimental energy sources without producing vehicles completely dependent on some external infrastructure.

    Heck, I'd like to see a 'standard' for pluggable electric generators in series hybrid cars, pull out the diesel engine, replace it with a hydrogen fuel cell, or a bigger battery pack, or just leave it out and have a pure electric car.

  13. Re:Growth on Apple Surpasses Microsoft In Market Capitalization · · Score: 2, Informative

    Um, no. When you own stock, you own a part of the company. As in, you own a part of a real company that is designing and building things and making money. That has intrinsic value independently of the dividends. To say stock that doesn't pay dividends doesn't have value is equivalent to saying this gold bar is worthless because it doesn't pay dividends. Both stock and the gold bar have value in the future because they represent actual wealth.

    Whether a company's profits go towards increasing the stock price or paying out dividends is not really relevant to the intrinsic value of owning a percentage of the company.

    DjVu is a good distribution format, but they want an archival format. something that can store everything down to the grain of the paper and the pen strokes used to write them. And not neccesarily just in the wavelengths of "red" "green" and "blue", they may want bands that preserve the previous works on palimpsests. FITS allows storage of much more data than just what is required to look at the page and have it look like it would to a human holding it at arms length. They want something suitable for scientific analysis in the future. But yes, if they were to distribute them on the web for viewing by humans, DjVu would be a fine format to do it in indeed, just not as the main archival format.

    If you had a supercapacitor able to hold as much energy as the battery can in order to slowly recharge it fully. Then why use the battery at all? Just run off the supercap.

    However, this may help if you had a whole lot of little recharging stops to give the supercap a boost and let it charge the battery while driving, but that has its own issues and you would still need a supercap of the same order of energy density as a battery.
