Agreed. I don't understand why they are bothering with this since they are suing her for sharing RIAA owned files, for uploading them, not for downloading them. I don't see how showing that her files have a particular md5 hash helps their case at all. Whether she actually owns the CD or not, they can still (try to) nail her for uploading them.
Although it's pointless in this context, embedding a message like "RIAA sucks" or "Boycott RIAA labels" with steganographic mp3 encoders like stego-lame or mp3stego should alter the MD5 quite significantly. I seriously may start doing this.
it's entirely plausible that the Martian sky could vary all the way from an Earth-style high-altitude deep blue to a total-sunset deep red
Does mars even have a sufficiently dense atmosphere to have a "color"? Maybe the red color is just a result of the Arizona-like martian soil.
This is because the there is a higher intensity of red light in sunlight than blue
If you examine a planck radiation curve for a 5800 degree (or any other) black body, the slope of the curve appears steeper at wavelengths shorter than the peak, implying that there is slightly more energy in the longer wavelengths. Whether this is significant enough to influence Rayleigh scattering I don't know.
550 nanometer yellow-green light, the intensity peak of solar radiation is exactly equidistant in wavelength between 400nm violet and 700nm red. If you assume a symmetrical curve the intensity of the red light should equal the intensity of the blue. Of course, the curve does not appear *exactly* symmetrical.
Dust particles will produce a red color because they are much larger than the nitrogen and oxygen gas particles. The wavelength of scattered light is proportional to particle size. Larger particles mean longer wavelength red is scattered more than shorter wavelength blue.
You freeze somebody, and they're still alive, all that happens is all the chemical reactions in their body slow way down (a good rule of thumb is reaction rates halve for about every 10 degrees).
If the liquid in the animal's body freezes, it expands due to that unfortunate (in this context) and unique property of water. I believe that some or all of the cell walls are ruptured when that happens. Some animals have a kind of antifreeze in their blood which merely lowers the temperature at which this happens.
I don't understand why Dyson would believe some kind of "solar collector" would be necessary. As someone has mentioned, the primary energy source on Europa would be the huge tidal forces from being right next to a (jovian) "planet" nearly big enough to be a star, big enough to make our planet look like a miniscule little dot in comparison.
No. Americans have proven that they will spend money that they don't have and I don't want to end up paying your medical bills because you decided that you'd rather have a new car every year than put money into a retirement account.
That's a false dichotomy. If I choose not to buy medical insurance then I would have to rely on charity, either an organized one or just the kindness of doctors/nurses to treat me without pay at a free clinic or something. No one would be forcing you to pay. In any case, you're paying anyway through medicare taxes. Your argument makes no sense.
You don't fund government based on a popularity contest.
So you are against democracy then? Perhaps you would prefer a King to decide these things for us.
You don't let taxpayers direct billions of tax dollars to saving baby harp seals while allowing a non-mammalian species to be wiped out -- just because the latter aren't cute, furry, and round.
And just who are you to decide what people should do with their own money. You're not the one who had to mop floors all week late into the night for that money. Let them decide for themselves what's "worthy" and what isn't.
That's the kind of stupidity that would take place with extremist Libertarians in charge.
An "extreme" Libertarian is a bit redundant. To the mainstream all Libertarians are extreme. For instance, a Libertarian would not need to think about where to direct funds from tax dollars because there wouldn't be any, just voluntary donations. So I guess baby harp seals would be sitting pretty.
Agreed. How about some big tax cuts for the poor? While we're at it lets eliminate social security and medicare taxes, which are totally regressive. Maybe then the "working man" will actually have some money left over at the end of the week.
To solve the NASA budget problems we could simply allow taxpayers to choose where their money goes based on categories. That way the most popular categories would get the most funds. I would put a check next to NASA to recieve all of my tax dollars. So let's just vote Libertarian (but one's that are space program friendly) and forget about those other ones.
Know where to find plans to build something like that these days?
Actually, where I live, the police are mostly using lasers. There are laser "jammers". Most of them don't work, but one or two might at least shorten the range. And, even when they aren't using lasers they almost always use Ka band, a band for which no radar jammers have been designed. Whatever you do don't believe the hype on the net about them. There are a lot of scams. The "passive" units don't work. My old Phantom RCD active jammer broke many years ago. If I still have one I could try to reverse engineer the circuit to get a schematic. It only worked against X and K. So it doesn't really seem worth the effort anymore.
With a good radar detector...you don't have to pay attention to the speed limits...
Actually, I used to have a radar jammer back when they used to work, and I would routinely pass by cops at the side of the road in excess of 90MPH. No lights or sirens. Usually the cop was too busy trying to figure out why his display said ERR or something.
When (not if, when) they try this in S. Illinois, they will have a revolution on their hands.
I wouldn't be too sure of that. That's just wishful thinking. It's in our future too. I think the majority will actually be in favor of it.
The natural progression of any government is to gain more power and control over its slave/citizens. Electronic monitoring is the next logical step. Orwell was mistaken of course. He should have named his book 2014. He was off by just a few decades. Maybe that means well get a HAL9000 by 2033. It will be used to control the uncooperative citizenry.
Slow drivers need to lose that same "me first" attitude and realize that the people behind them may actually have some kind of a life and can't leave an hour early for everything just in case they get behind someone like you.
Slow drivers cause more fatal accidents than fast ones. That's why there's a 40MPH minimum. What could possibly be wrong with you that you can't handle driving any faster than 40MPH?
I will admit that when I pass a driver doing half the posted limit on a secondary road with no sight distance I am taking a very significant chance that I will kill whoever is approaching in the other lane as well as myself. Since I am willing to risk immediate violent death in order to do it, no law will help with this of course. Will that slow driver feel at all responsible for all those deaths because he continued to drive so slow without pulling over for other cars? I doubt it.
Most of it was. The velcro shoes. The artificial gravity through centripetal force from a spinning ship. And, as far as I have read, even that moment when he survived being ejected from the pod into the vacuum of space without his helmet by just holding his breath.
I think that particular scene was questioned by quite a few people. I know I did. I had always heard the theory that the inside of our bodies have pressure. Since space does not, the idea is that, without a pressurized space suit, we would explode or at least be killed by exposure to the vacuum. This hypothesis has actually been proven to be false. Here's another link with some discussion of the topic. I used to have a much better link that discussed all of this including some info on a Russian astronaut who recently died in space, but I can't find it.
I find that many Europeans who learn English speak with a British accent. Were you expecting an American or Australian accent perhaps? England is the closest English speaking country to France.
There are probably many Americans who speak Spanish with a Mexican accent for a similar reason.
This water pump with no moving parts seems great. I'll be the first to buy one once the price drops from the $1000 that it's likely to start at down to like $50. It doesn't solve the problem of creating a quiet pc though.
Historically water cooling has been used more for overclocking than for quiet PCs. There have been some experiments in passive, convection based, water cooling. One experiment was particularly interesting, but I can't find the link. One trick is to use very large diameter tubing. The larger the diameter of the tube the slower the water can move and still cool the CPU.
Unless you attempt some kind of open system that gets water directly from the house plumbing or groundwater, you still need a radiator and fan to cool the water. The advantage is that you can go to a larger fan or even two or more fans and a much larger heatsink (radiator) than is possible directly on the CPU.
With an open system, you could put that waste heat to work as a water heater with the addition of some kind of storage tank.
Have you read much about the Pentium M? It is indeed a very interesting chip. There seems to be a "ULV" model that will run at 0.85 volts and 600Mhz. The Pentium M architecture is not wasteful like the Pentium 4. It has a higher Instruction Per Clock rating, higher than the Athlon XP and maybe as high as the Pentium III. Now if Intel would just sell these for desktop motherboards. They definitely seem like a step in the right direction. It makes me wonder how low they will be able to get the voltage when Intel starts producing them at.09 microns. Could it get down to half a volt? Remember that power is proportional to the square of the voltage. So reducing the voltage is much more effective at reducing power and heat than reducing the clock speed.
On one of those discovery channnel shows I saw some video footage of some guy who actually built one of these drives in his powerboat. His particular drive wasn't really powerful enough to get his boat going very fast though. A few Knots I think.
Just go over to silentpcreview for the scoop on the rest of your components. Apparently the Seasonic SS-300FS is the best power supply at the moment. The papst fan is a good choice. I just bought several of those strange and expensive ring fans that Panasonic makes. Some air escapes through the slots in the side, but it is pretty quiet. You can get those at Digikey and the 80mm fans are less than $9. I'd recommend the "medium" speed.
I went with an Intel Pentium III-S 1.13 Ghz. I plan to under-volt it down to near 1V and underclock it down to whatever its 66Mhz motherboard speed is. Even at its full voltage and clock speed it only uses 29 watts, so I figure I can get down to less than half of that.
Also, don't buy two hard drives. Each drive will double the noise and power consumption and heat. I just bought a 160GB Samsung with a very quiet idle and seek to replace my 80GB Seagate 7200.7.
Another tip is that the airflow of the low speed fan models are not very impressive. Where you actually want some airflow, you might want to get a higher "medium" rated fan and wire it for 7V (red to yellow, black to red) if it's too noisy at full speed. Their specs allow for 7v operation and it gives you the option of moving more air should you want/need to. Obviously you'll have to stick with Papst, Pana, or NoiseBlocker
Actually, AFAIK, water heaters with gas or oil fired burners do need electricity to run. They may not use much, but they do need some. They won't run in a blackout.
Last time I checked neither the Intel nor AMD plans included organic processors in 5 years. And they do plan 5 years ahead. But I'm just a human. Let me ask HAL here... Oh yeah. We haven't yet been able to even create a computer with the intelligence of a 2 year old child or a grey parrot or a chimpanzee. I forgot.
Well, anyway, I'm late for my inexpensive trip around the rings of Saturn. Oh yeah, even though we landed on the moon over 30 years ago, no human has traveled beyond it. Were you alive when the first human stepped on the moon? Wake me up in a couple of months when we have holodecks, intersteller space travel, replicators, transporters, time machines, and organic computers. I'm sure it's all just around the corner. And there's certainly no question that we'll all live to see it because the problem of immortality will surely be solved before 2005. Until then I think I'll just take a short nap.
As has been said here many times, a true democracy would mean a referendum on every issue. We would not vote for people. We would vote for laws, just as our "congress" does now.
To me, democracy misses the point. The point is that no law should be enacted that takes away from an individuals rights ("rights" not entitlements). Anything else that the majority might want is fine, but it's not much better in my view than a simple monarchy with an intelligent king. And any "constitution" should not be changeable, regardless of the vote.
Where did you get the idea that Cuba is a democracy of any kind? Nobody ever votes there. Everyone who has a (legal) job works for the government and they are paid mainly with food ration coupons.
Interesting story. What I don't understand is that he wanted to cool a nonconductive liquid with liquid nitrogen, but what was he planning on cooling the liquid nitrogen with? It seems like he had no plan for when the nitrogen would phase change to a gas and warm up to room temperature and above. Maybe he planned on just replenishing the system with more liquid nitrogen after it warmed up. It seems like he was missing a viable refrigeration system.
Sounds like you need to upgrade your CPU fan to an 8000 RPM Delta fan. AT 55 decibels, It should keep you up all night. I put one in my system once but couldn't stand to be in the same room for more than 5 minutes so I promptly replaced it with a Panasonic Panaflo.
You still have the problem of cooling the fluid though. As with water-block cooling, you still need a heatsink and fan (radiator)at some point. The heat needs to be transfered to the air. The more efficiently your computer heats your room the more efficiently you are cooling your computer. That's what I like about combining a case with a gigantic heat sink.
Slashdot Mirror
Agreed. I don't understand why they are bothering with this since they are suing her for sharing RIAA owned files, for uploading them, not for downloading them.

Perhaps a reverse md5 hash generator which takes a hash and generates a file.
And while we're on that subject let's try not to give our enemies any ideas.

Those displays are notoriously inaccurate. You'll need to do better than that if you want to check the accuracy of your speedometer.

It is amazing how so many people don't even know the most basic science. Even calling it physics is a stretch.
Try asking people why the sky is blue or even (a bit easier) why clouds are white, for instance.
