If they charged a real toll instead and then bought electricity made from the same fossil fuels the cars would be wasting, it would probably be more efficient.
I have believed as long as I could think that the universe is nothing. All of it's contents percievable and impercievable (important) sum to absolutely nothing. Nothing is everything and vice versa, because with nothing ELSE to relate "everything" to, "everything" doesn't exist.
It's only within certain contexts, limited portions of the whole, that anything's definable.
I also believe that the impercievable portion of space time is infinite, and consists of everything that could ever be.
The idea isn't disprovable, is useless, but it gives me piece of mind somehow --like I've realized something important.
For anyone that knows their stuff about car engines, this article is a joke.
Both turbocharging and direct injection are preexisting technologies, and neither looks particularly impressive. Indeed, used separately, they would lead to only marginal improvements in the performance of an internal-combustion engine. Really? So there aren't people slapping large turbochargers on little 3 liter supra engines and increasing the engine output 5-fold? Or is that only marginal?
That aside, the problem with this is that a turbocharged engine at full output is very inefficient. A larger naturally aspirated engine will always be more efficient than the small turbocharged engine of the same maximum output. That's because a lot of energy is wasted compressing the intake charge, more than can be made up for with the displacement decrease, even with the newest fanciest garrett turbos. The only merit efficiency-wise of turbo engines is engine efficiency at low loads (when the engine is not under boost) relative to the maximum output.
There is obviously a balance to be struck here, and that's why 18 wheelers have big v8's with turbo chargers, rather than even bigger engines or smaller engines running under high pressure. Designing a motor vehicle is always a balancing act, and in most cases a turbo is not helpful because of the cost, reliability and other shortcomings versus the benefits.
Recently, car makers have started using direct injection to combat preignition that can damage an engine. It allows them to run leaner fuel mixtures, higher compression and more aggressive spark timing, improving the power/efficiency of engines. Direct injection has the exact same benefit with turbocharging. There are no compounded benefits from mixing the two technologies.
I have burned lots of cds and handed them out for free. Just making it is fun and having people listen is satisfying. IOW, it's a hobby.
There are some recent works-in-progress and one finished song at myspace.com/a4r6.
As Sir Isaac Newton said,
"If I have seen a little farther than others, it's because I stood on the shoulders of giants." You need to learn what is already known (IOW climb up onto those shoulders,) before you try to offer any insight, or you're really wasting your time.
More memory is one thing, but the level of parallelism in a brain is what makes it so good at complex problems.
Let's say you have one computer that knows one make and model of a car, then 1000 other computers that all know about one other. Issue some visual clues to all of them at once for comparison, and a few of them respond with varying degrees of certainty, but one stands out as the closest match.
There is no DO LOOP stuff going on at a low level, and that's the reason for our efficiency, as I understand it.
Agreed. I work for a school district where we run every specialized oddball program on a network that uses roaming profiles, and everyone has limited rights to their PC.
The capability may be there on the windows side for things to work seamlessly, but most of it was developed without a bit of thought into how it might act on a network like ours.
IE:
software that puts important stuff into the users profile or into the user registry hive that it can't run without, forcing us to make special "reinstallers" that run for every user that logs into the workstation.
software that requires read/write priviledges to random places on the local drive or parts of the registry which normal users don't normally have.
software that uses the users profile as a cache area, making the profiles huge and causing slow login and logout.
permissions and multiple users can be a huuuge PITA
It'd be great if we could do the same thing for DirectX 10 --remove the artificial limitation I mean.
I found some code leaked from DX10 a while ago...

We have a bunch of CRT monitors that are much more yellow than others, but in a pattern that suggests its from a cleaning agent someone used. (All the ones in one room, only on the visible easily accessible portions) My best guess is the plastic doesnt like ammonia-based stuff like windex.
Hell, put the student population of Caltech in your local community college and you'd find all sorts of revolutionary science suddenly springing from there too.
Without the facilities and faculty of the former school I don't believe the students would come quite as close to their potential. If the environment wasn't important, no one would attend a university.
Motivation and discipline are different things. Self-discipline is to some extent a substitute for motivation. You do something because you have determined that you should through reason, not because you feel that you want to in the short term. However, you can't get anything done if you're completely lacking either.
Where to get self-discipline? That's something you learn growing up, and it's harder and harder to learn as you get older. It's mainly by example: from parents, from peers, and through personal experience.
As for motivation, I hear it's called Adderall. (More seriously, it's an emotional thing, and is built through encouragement and affection throughout life.)
Yipee, XML. A standard for people too lazy to interpret data in a minimal and efficient format.
If you've had time to play games in previous jobs, and you have the ability to play it in a current job, chances are you are going to play games still. That is, of course, unless you found a job which is actually demanding and interesting at the same time, which is very unlikely.
1) A 100% solar earth IS unlikely, but if 50% of it can be solar without long distance transport issues or terrible efficiency, why aren't we striving for that?!
2) Storing that much juice over night may be somewhat impractical for now, but supercapacitors, flywheel energy storage, and improvements in battery technology or chemical energy storage are all working to make it practical. Even converting excess energy to hydrogen, as inefficient and space-consuming (IOW, COSTLY, boo hoo) as it may be, works, and automatically makes solar production worth-while, for it's other merits. A huge amount of man power is used coming up with new ways to consume the energy we have, I think it's ridiculous that we aren't working harder on keeping a sustainable source and climate to consume it in. The Free Market along with our political community is just too stupid to have any foresight.
3) A solar infrastructure is not mutually exclusive to our existing infrastructure. Redundancy is a no brainer.
Agreed...
I just bought some really nice headphones for the first time. AT ART-550 I think?
The quality difference is impressive, especially spatially.
I can make out distinct sound sources very well even in the dense parts of songs.
I have done some tests comparing original CD tracks to those encoded with OGG @ 200 and even with the nice headphones it is difficult to hear a difference, whereas the difference between headphones was very noticable.
If there is one thing lacking in audio reproduction in general it is dynamic range. If you want a recording that has an average volume of 1/4 the maximum, to accomodate very loud sections, you have lost 2 bits of accuracy right there. On top of that, with the amplifier turned up high enough to accomodate the loud sections, the noise floor is closer to the quiet sections.
I think that amplifiers that work similarly to the very high contrast displays I've read about, the ones that have backlighting which scales with the signal, along with high bitrate recordings, could greatly improve reproduction in this sense. (Either have the amplifier intelligently change its level and shift the noise floor up and down as peak volume changes throughout the recording somehow, or include a signal in the recording which controls the level of amplification of the audio signal, which could be fed to the amplifier)
With the exception of classical recordings, this would be mostly useless, though. Most modern recordings have a lot of compression and are very normalized. I think most people prefer music that has a small dynamic range because they can keep it at a volume they like, one that's easy to hear but not too loud to disturb anyone else.
Where do you get off lumping together environmentalists and animal rights activists?
Oh wait, you are really just talking about "liberals", and treating them as one thing, aren't you?
I happen to believe that our geo-engineering is part of our future, and is necessary because of huge imbalance we have created. Global warming is a problem. Science enabled us to do it and will give us the power to "fix" it.
I am strongly against wasteful use of resources, SUV's as single-passenger daily drivers, and disposable-everything.
I am not scared of nuclear energy. I am the opposite of terrified regarding research. I think that we should be throwing several times the resources we do at alternative energy, regardless of what it does to our precious economy. I don't like the fur trade, or cruel experimentation on animals. I enjoy meat.
I consider myself a liberal, but that doesn't make me all things liberal.
...at the $300 level, and we'll provide you with a big hideous print of a badly rendered Noah's Ark, complete with velociraptors!
Remembering at the $1000 level gets you the SAME hideous print, plus a frame to put it in and a poster with all the other hideous pictures on it!

I believe it should read "Previous studies have shown" rather than "showed" because it's in the past perfect tense.
What if someone thought about molesting your baby?
What about OFFROAD? Eventually the game becomes a button-pushing fest between rounds when everyone dumps all their money into Nitro.

Partly at least.

No, see, all the code has been written already! All we need to do is cut and paste!
