Energy cannot be created or destroyed, only changed.
Sure it can. Have an anti-proton meet a proton, and you end up with no matter and all energy. Unless you are referring to the equivalence of matter and energy, in which case, please be more precise in your statements.:-)
There's a lot more than just encryption riding on the answer (and as you say, encryption not so much) as tons of useful algorithms would go from intractable (exponential) to tractable (polynomial), and that's why people have been looking at the problem for so many years. Without success.
Great point. Showing NP=P would probably result in more benfits than harm. There are tons of efficiency sorts of problems (analogous to traveling saleman) that are NP that if they could be solved in polynomial time would result in huge increases in efficiency.
But, I expect if any proof occurs it will be that P != NP.
the legal presumption is that the copyrights still reside with the original owner: in this case, Novell.
Yes, but I don't think judges often go beyond the minimum needed to decide a case. And, in order to decide the slander of title all the judge needs to rule is that it is questionable whether SCO owns the copyrights, and therefore reasonable and without malice that Novell made the statements that they made.
IANAL
The just thought of a problem though. SCO could now file a contract case regarding who owns the SVR4 copyrights. This could have bad repercussions, in the sense that SCO could get delays in other cases while the new one just gets started.
The problem is if the copyrights are in question. I don't think that decides the RedHat case, but might result in dismissal without prejudice or a continued stay with an injunction telling SCO they must discontinue interfering with RedHats business until the copyright case is decided.
Autozone woudl probably continue to be stayed. And, there may even be the possibility that IBM gets stayed. Although if IBM doesn't request the stay, I am not sure SCO could without severe embarassment.
SCO: "Sorry judge, we submitted this lawsuit too soon. We need to clear up who really owns the copyrights to SVR4. Could we get a stay until the Novell case is decided?"
Maybe they could get a stay on a couple of the counterclaims, and continue with the rest since they characterize their claims as contract claims. Either way whiel SCO submitting a copyright case against Novell would clear everything up eventually, (probably in Novell's favor). I could result in SCO getting more time to bluster.
The other theory was that the oil used on the power lines contained chemicals like benzene, which were known carcinogens.
This is an important point that is no emphsized. What are the other things other than radio waves associated with AM towers? And, can they cause cancer? Assuming the correlation panned out, correlation with AM towers does not equal causation by radio waves.
This part of the article struck a cord:
Moreover, many lab studies show low-frequency EMF disrupt living cells, Milham asserts. Critics like McBride say such results are often difficult to reproduce at other labs. Milham says that's because of differences in the Earth's magnetic field and stray EMF.
That sounds a lot like cold fusion experiments. And, if it looks like a duck, walks like a duck, and quacks like a duck...
Regardless of that, I happen to agree with forcing people to identify themselves when they are being questioned. If the reason for questioning is bogus, that's another issue, but there is absolutely no justification for hiding who you are from the police unless you are involved in something you shouldn't be.
But, isn't it ironic that a person being arrested has a right that some one being questioned does not? When arrested I have the right to remain silent, and last I checked that wasn't qualified with "except you have to tell me your name." Or, think of it this way. I kill some one and everyone sees it and the cops see it, but no one knows my name... I don't have to say a damned thing. I am walking down the street doing nothing, but happen to look a little like some junkies description of a guy who killed some one and I have to state my name.
No, but a legitimate suspicion that is worthy of investigation has been raised. If as a result of that investigation it is found that it was groundless, then there is no harm done, but if they did not respond to calls such as that then the police would not be doing their jobs properly.
But, isn't it weird that once you are arrested you have the right to remain silent, but before hand you do not?
Okay, so he says that Linux might not be good for the s/w industry ( uneducated and uninformed as he is, he is most likely wrong ) - but is that the only industry there is in this whole world ? dont the other industries ( who have been held to ransom, more or less by organisations like MS and Sage ), also have a right to benefit ? If you look at the reality - the user base is many many times higher than the provider base. So how does the economy suffer ?
This is something that I wish more people would get. In the big picture software is an expense that is paid by those producing end products. There are some exceptions where the sofware is an end in itself (games come to mind). But, they are few. A spreadsheet is simply a tool to increase productivity and reduce costs The price paid is a transfer of some of the savings of that increase in productivity to the software developer. If a sofware development model comes about that reduces the cost of the software i.e. how much is paid to the developer (or uses fewer developers), then that is a good thing.
What we want to see is the minimization of the costs of software, that is the best thing for the economy because then resources can be routed to productive undertakings. The ideal open source situation minimizes the cost of software, by distributing the developers among the end users. Thereby eliminating a complete management organization, and eliminating profits paid to another organization. i.e. the cost of Bill Gates and much of the Microsoft infrastructure is eliminated.
Now if you come up with a calculation that if you completely covered the sunny state of Arizona with solar cells, it would still not be enough to replace just coal, you're on the right track.
Wrong! Did you even bother to make the calculation?
155W solar panel is 42"x49". http://www.partsonsale.com/photowatt.html
Let's say 150W/sqm.
Let's take an average daily solar available at 4 hours. This averages out 8 hours of sunlight to account for low angle of incidence at different times of day. 4 hours is very conservative. So,.6kWh/day/sqm.
219kWh/year/sqm
Now 3,848,000,000,000 kilowatt-hours/year divided by 219 kWH/year/sqm is about 17,600,000,000 sqm which is 17,600 sqkm or 6800 sqmi. Or, a square 132 km/side or 82 miles on a side. This is large, but nowhere near the size of the state of Arizona. Using Arizona as a reference that is a little over half the size of Maricopa County. Using a California county, about the same size as Riverside County. Huge no doubt, but only 6% of the state of Arizona.
It is really not trivial what to do with the waste. Myself I think it should be sent under the magma. Find a location where tectonic plate subduction occurs and drop the deep sea waste cells there. By the time it comes out it won't be radioactive anymore.
Pretty close we know how to drill deep ocean cores. Drill a hole in the ocean floor and drop barrels of waste in backfilling with a meter or two of the previously extracted sediment. Do this close enough to a subduction zone that in a few thousand years the waste is melted into the mantle.
Worst case scenario is accident at sea causing the loss of the waste barrels into the ocean. 2 ways to mitigate; 1) make sure barrels don't float, 2) Don't transport huge amounts per shipment. This will make sure that the wast ends up on the sea floor and not floating around to land on some beach. And, by limiting the qunatities per shipment it makes sure the inevitable accident results in a small enough release to be negligible comapred to the total oceanix mass.
Once in the hole, even complete failure of the barrel, and say liquification of the contents. The contents just cannot propagate through ocean sediment very quickly. Stop dropping barrels 100m or so from the surface and there is no chance of the waste material propagating to the surface before it is subducted into the mantle.
A single photon can't go through multiple pinholes
This is the part that I think screws everyone up. This assumes that what we call a single particle really is a particle and not a wave or superposition of many waves. In that case, what we detect as a particle would be a peak in the wave, but the entire wave is smeared out over a much bigger area. So, the "particle" does pass through both slits even though the peak that we detect as a particle only passes through one slit. The no peak portion that passes through the other slit interferes with the peak and alters the location of the peak.
I guess the portion of a particle smeared out would be analagous to Deutsch shadow particles, but would not require extra universes.
If it is just a complex interference pattern, how can individual photons reproduce the same pattern when there is nothing to interfere with?
IANAP
What you mean is if you send 1 photon at a time and have a detector detect each photon individually as it impacts the wall, destroying said photon in the process before the next photon is emitted, the detector will show the same pattern even though each photon could not possibly have interfered with another photon.
My answer would be that the photon interfered with itself. Particles are waves and what we detect as a photon particle could be a sort of peak of that wave. So, part of the wave passes through both slits interfering with itself and altering the probability of where the peak will hit the detector and be detected as a particle.
So, the question then would be why can't we detect the portion of a particle's wave that passes through the other slit. As I said before IANAP, so I couldn't even begin to figure out how or if something like that could be detected. I think the best experiment, if it were possible, would be to perform the experiment with a Bose-Einstein condensate. Or, better yet, individual particles used to make a Bose-Einstein condensate cooled to a state where the particle is smeared to a size where they are actually bigger than the spacing between the slits. Then, move those particles through the slits. If they can be detected at the other side, and show an interference pattern, the particle went through both slits, and interfered with itself.
The thing that always made Schrödingers cat seird to me is that the cat is not counted as an observer of itself. I may not have seen if the cat is dead or not, but the cat sure has. So hasn't it collapsed the wave function? Would it be different if it was a human in the box?
That is because Schroedinger's cat is a simplification to try and explain the phenomenon using more commonly known objects. Air interacting with the cat collapses the wave function. Air interacting with the released poison collapses the wave function. The cats material interacts with itself collapsing the various wave functions of the cat's particles. Whatever mechanism detect the decaying particle in order to release the poison collapses the wave function.
This is why if you run the two-slit experiment but put a detector by each slit to watch for which slit the photon passes through, you don't get an interference pattern.
Umm... Isn't that because the photons don't make it past the detectors in order to create an interference pattern?
I'm glad. Maybe this will discourage more companies from jumping on the hybrid bandwagon, and spend their research money on hydrogen-powered cars instead.
Hydrogen only becomes viable when solar, nuclear, wind, and/or water provides sufficient energy to not only cover electrical conversion, but all the enrgy required to convert water to hydrogen for every vehicle. It is not even close to reality.
Fuel cells are interesting, but not with hydrogen at this point since the fuel cell efficiency advantage is lost due to the need to make hydrogen for it. Fossil fuel (methane or gasoline) fuel cells could be interesting as they may be able to get more useable energy than burning the fuel.
Read the original PCWeek article. It is retail only, and retail appears to be a relative small amount of the total market. At the bottom it says Intel had 83.6% of the x86 desktop, server and notebooks, and AMD shipped 14.9%. Assuming all of AMD's shipments were for retail desktops (they are not), that would mean retail desktops at maximum could be 28.8% of the market. Reality is probably down near 20%.
I think the point for AMD is that for the first time as far as we know they have actually surpassed Intel in sales in any significant portion of the x86 CPU market.
No one has mentioned this so I will... On avsforum many people have had success with pulling black out cloth over a wood frame in order to create a fixed screen at a much lower cost than Da-Lite.
Don't get anything with less than 1000 lumens brightness. Around 1500 is probably OK for up to a 5' wide screen if you don't keep the lights up too high. Much more than 2000 is probably wasted unless you have a very big screen or want to use it somewhere in addition to your living room.
This is not entirely true. For a dedicated home theater room where the light level can be controlled you will end up calibrating the projector aperture to output around 500 lumens or less for maximum contrast. Your advice on lumens though is probably correct for a family room with windows and drapes. The Sharp Z2 and Panasonic AE500/L500 get great reviews but are onyl rated at about 800 lumens, you just shoudl not try to use them somewhere where you cannot control the light sufficiently.
My beef is the lack of true 1080i support. Supposedly, the LCOS chips coming will be able to support 1080i, but I haven't actually seen these projectors yet.
Actually it is not likely you will ever see any DLP, LCD, LCOS, or Plasma display have true 1080i support as they are inherently progressive scan (as currently designed). Best case 1080p which is easier to convert to than 720p. And, that still screws things up because 720p is considered true HDTV, and is broadcast by ABC. Therefore, no non CRT TV will be able to display all HDTV resolutions natively until 3840x2160 displays come along.
But after comparing a few units, I settled on the NEC VT46, with a much brighter image and significantly less fan noise. The moral of the story is: go see the unit of your choice first before spending your money.
Brighter is not necessarily better, especially in a light controlled room like a dedicated home theater room. The Panasonic L500 is getting good reviews from avsforum and other reviewers, but is rated as 800 lumens. One reviewer set it up and after adjusting the aperture for the best picture measured the actual light output as 450 lumens. The reason for this is that a lower light output will result in better blacks. As the screen gets larger more light will be needed, but resolution issues will start to occur at the same time.
But, you are correct audition a projector before buying it. Hpefully under lighting condtions similar to your room.
That means investing in a reliable high-capacity, high-orbit vehicle.
I am not sure that is necessary. The main need is an inexpensive means of getting to any orbit, low earth orbit is sufficient. Once you can get out of the atmosphere reliably and cheaply, getting to other places involves transporting the pieces and fuel for a space ferry for assembly in low earth orbit. Then, getting anywhere else is a lot easier and your spacecraft takes much less of a beating because it doesn't have to take off and land.
Actually, the ferry is most likely just a propulsion system with controls and places to attach modules. i.e. crew quarters, payloads, etc. Sort of a moving reconfigurable ISS.
There are plenty of jobs in the states - people just don't want to do a lot of them - else there wouldn't be a bunch of illegals coming to the US to work. Ohhhh... those jobs are beneath everyone you associate with?
If the illegals didn't come in, the employers of those illegals would have to pay higher wages in order to get people for those jobs. That will of course increase their costs, which will be a great incentive for them to modernize and automate in order to increase productivity of the higher paid workers. You then end up with 1 person doing work that previously took 10 or 20 people at a lower cost. While being paid 2,3,4, or 5 times more than the illegal worker. Cheap labor hold back innovation, improvements in productivity, and the subsequent improvements in living conditions.
That's the weird thing about the place. It's considered basically uninhabitable by humans. Yet nature as a whole seems entirely unfazed by the radition and is thriving in the absence of humans.
That doesn't mean there is no impact from the readiation. It just means that on average across the whole population of animals living in the exclusion zone, humans were worse than radiation.
The other thing is in this case thriving means reproducinig more and sustaining a higher population than before the incident. Thriving does not mean living longer or not dying of cancer.
No, he isn't obligated to provide service to anyone for free just as the county is not obligated to pay someone for work THEY AGREED TO DO FOR FREE.
Right. But, that still makes pulling the plug, not extortion. I did just think of the one way this could be extortion. If the defendant threatened to destroy the content. The content could be considered a gift to the county and owned by the county, therefore destroying the content might make it extortion.
Regardless this should have been a civil matter, not a criminal matter. The sheriff sues, and gets the domain and content transferred to the county. The downing of the site becomes a black mark on the defedants reputation, and the county pays some else to put the site back up and maintain it. If the content were destroyed. A judgement for the cost to restore the site could be entered against the defendant. I still think criminal charges are a matter of the sheriff being pissed and deciding to be vindictive rather than deal with the real damages.

There are plenty of jobs in the states - people just don't want to do a lot of them - else there wouldn't be a bunch of illegals coming to the US to work. Ohhhh ... those jobs are beneath everyone you associate with?
If the illegals didn't come in, the employers of those illegals would have to pay higher wages in order to get people for those jobs. That will of course increase their costs, which will be a great incentive for them to modernize and automate in order to increase productivity of the higher paid workers. You then end up with 1 person doing work that previously took 10 or 20 people at a lower cost. While being paid 2,3,4, or 5 times more than the illegal worker. Cheap labor hold back innovation, improvements in productivity, and the subsequent improvements in living conditions.
That's the weird thing about the place. It's considered basically uninhabitable by humans. Yet nature as a whole seems entirely unfazed by the radition and is thriving in the absence of humans.
That doesn't mean there is no impact from the readiation. It just means that on average across the whole population of animals living in the exclusion zone, humans were worse than radiation.
The other thing is in this case thriving means reproducinig more and sustaining a higher population than before the incident. Thriving does not mean living longer or not dying of cancer.
No, he isn't obligated to provide service to anyone for free just as the county is not obligated to pay someone for work THEY AGREED TO DO FOR FREE.
Right. But, that still makes pulling the plug, not extortion. I did just think of the one way this could be extortion. If the defendant threatened to destroy the content. The content could be considered a gift to the county and owned by the county, therefore destroying the content might make it extortion.
Regardless this should have been a civil matter, not a criminal matter. The sheriff sues, and gets the domain and content transferred to the county. The downing of the site becomes a black mark on the defedants reputation, and the county pays some else to put the site back up and maintain it. If the content were destroyed. A judgement for the cost to restore the site could be entered against the defendant. I still think criminal charges are a matter of the sheriff being pissed and deciding to be vindictive rather than deal with the real damages.
IANAL
