    Well, Socrates put it nicely, "I know that I know nothing." However, the article is there and it is about valid warrants. If the warrant turns out to be invalid then this changes it of course, but I am going to assume for now the discussion is about valid warrants. If they believe it is invalid then I will just stand by what I have already said above and that the defendant should go for an appeal...

    Fact is people in the South of England have already started growing grapes in order to produce wine. Global warming could turn England into a wine producing country such as France currently is. Researchers predict the British Isles will turn from a cold and rainy island into a tropic zone and become a holiday paradise. With such an outlook on global warming who in their right mind wants to do something against global warming?! I do not believe too many Brits still care about global warming.

    No. You are arguing a lost case. Again, the problem is not that the data is outside the country. The problem is that the judge has ordered them to produce the information. This is not some silly request by the judge asking them with a "pretty please". They are to present the information to the court (aka judge and jury) as a result of a ruling by the judge. This is what is meant by "obligated by law".

    Now you can tell the court No, but it will be held against you. Yet, this is what they are trying to do. They had their chance to deny the information before the judge order them to provide it. They did not successfully fight it and lost at this particular stage. Now they are trying to twist it and to throw the court off, or, perhaps these e-mails contain information that is going to put them into much deeper trouble than they are already in. There is certainly a reason why they are not following the law here.

    Think of it as a murder suspect who is being charged with murder and who claims to have an alibi, perhaps a witness who is now living outside the US... The court now orders the suspect to bring the witness into the trail or else will the alleged alibi be of no use.
    Another example is a missing murder weapon... The attorney may have the dead body and they have witnesses, but they are missing the murder weapon and are now demanding of the suspect to provide information about the weapon's location. Could be the suspect is innocent, knows about the location of the weapon, but does not want people to know where to find it. Maybe the weapon is a 25kg gold bar, or the weapon was used in another murder case, etc..
    To give a third example, think of a criminal who committed a crime in the US and now flees the country. It may save the criminal from being sentenced to prison by a US court, but it is not going to prove the criminal's innocence and make the charges go away.

    In this case, with the e-mails, does it very much depend on what these are needed for. Their content, if provided, may or may not change the course of the trial. It all depends. Not following a judge's ruling is however always a bad idea. Maybe they have something to hide, maybe they do not and the companies' lawyers only want to stretch the trial to make more money, etc.. For the judge and jury will it make no difference if these e-mails are within the US or outside the US. Only their content will be of importance, not their location.

    Whatever, when you are obligated by law to produce the information then it means you have to, or a refusal to do so will be used against you. For all it matters could the missing information have been lost. It will not make the judge or the jury happy, and you do want them to vote and rule in your favour, right?

    "The *real* question is what about companies that do business here but are based in other countries?"

    No, this is not the right question.

    It does not matter where you do business or where you are based at. What matters is what your offence or crime is! Meaning, the reason why you are in court.

    Depending on what you did can your status have all different kinds of influence on the outcome or none at all.

    Of course, you also have to define what you understand by "being based at" and "doing business in". It often will make little difference. For example when you have to pay your taxes then the difference may only make a difference in which taxes you have to pay, but you will have to pay one or the other tax for sure.

  7. Dog carried my homework off to Mexico on Obama Administration Says the World's Servers Are Ours · · Score: 1

    What a nonsense. It is as dumb as trying to claim your dog carried off your homework to Mexico.

    When you are obligated by law to produce the required information then this is how it is. If you have placed the information out of reach for you to get it, or only refuse to get it, then it has got a fair chance to turn into an obstruction of justice and you will find yourself in even more trouble. It is you who is the American citizen and who is standing in front of an American court and it is you who will be judged and sentenced by the court. The information however is free to travel or to stay wherever "it" wants. Only you may not like where your own ass will be travelling soon, but you are free to find out the hard way of course.

    The only way to fight this is to fight the court order, which binds you to produce the information in the first place. If this has failed then try to go for an appeal or cut your losses. Of course, if you do not have a single decent bone in your body then you can certainly try to claim your homework was abducted by aliens. Who knows? Maybe you make everyone laugh and they will all forgive you for your sins ...

  10. Re:Inside of cameras on Scientists Have Developed a Material So Dark That You Can't See It · · Score: 1

    Its properties come from it being a "forest of nano-tubes". This makes it rather fragile when used in direct contact with other materials, which is also why it is so difficult to produce and needs to be coated onto a surface with a complicated process.

    One really wants to have less layers of conductivity than more layers when conducting heat. Coating a heat sink with the material would only add an additional layer onto it, though it would be one that conducts heat very efficiently, but it would still be an additional layer when one could possibly just leave it away.

    So the main application of this material for now seems to be with light, but who knows what is really possible?!

    They say it is several times stronger than steel ... Perhaps it could be used to create high-durable, heat-conducting brake discs for cars and trucks. Simply coat a lot of the material onto a steel disc and see what it does!

  11. Re:Insides and outsides on Scientists Have Developed a Material So Dark That You Can't See It · · Score: 1

    I disagree.

    Surely, it will help with optical systems, but blackness is not a primary problem. The bigger problems are with the sensitivity of sensors and internal heat. The biggest advances can still be made by increasing sensor/cell sensitivity, by lowering signal-to-noise ratios of electronics and by cooling interiors to reduce infra-red emissions. Earth-bound optical systems then have the additional problem of light coming from the surrounding atmosphere as well as atmospheric refractions. While in space do you have the problem of much larger heat built-ups plus you need to shield against the sun's thermal and electromagnetic radiation. The need for blackness inside optical systems is a peripheral problem. The new material will certainly not lead to a 28-fold improvement in imagining. Such a claim is ludicrous.

    With thermal solar power plants does it have many areas (main areas as well as peripheral areas) where small improvements lead to an overall improvement. However, the new material can be used in the centre of the energy conversion where its properties will have a direct impact. Its extreme blackness and its thermal conductivity will both take a direct impact on a plant's efficiency. These plants require large surface areas and a lot of direct sunlight to be feasible, but with no foreseeable end to our energy demand, will even the smallest improvements find their way into the next generations even when it means it takes a redesign of the plants.

    Speaking of redesigns, if you take a look at the next generation of space telescopes like the upcoming James Web space telescope, which has a unique design, will you see that its main advances come from its shielding and positioning in space. This will provide its optical system with more blackness and less heat, because instead of only wrapping the telescope into more and more layers did they simply reduce the need for layers, which is a major break from all the existing designs currently in orbit.

    So I stand by my statement that the new material will have its uses on "insides" as well as "outsides". The new material, while currently being complicated to produce, is simple enough and it only depends on what you make of it.

    I cannot believe this is seriously being considered. Not only for efficiency reasons, but for the fact that each rocket launch into high atmosphere always punches a huge hole into the ozone layer, consuming massive amounts of energy and resources, and is an all-round hazard for life on Earth. Why some people keep holding onto the idea of creating this kind of "fair ride", which in the end is exactly what it is, is beyond me.

    I do not see it as a problem at all. I find it is rather a positive sign and one should focus less on the names on a paper, but more on the content of it. When the bosses are listed as co-authors then because there was a cooperation that benefited all. If bosses are being reduced to "admin" then this can be a sign of too little or no involvement into the research that is going on. So it is rather good to see it happening.

    You get this kind of problem with many social networks. If this is a network of scientists where some people count only the sheer number of publications, or a teenage forum where trolls count "likes", "up votes" or their post count, makes little difference. It is a superficial attitude, where people refuse to look deeper.

    It really is (or should be) a non-issue.

    Sadly, it will not. Displays could certainly profit from this material if the blackness could be turned on and off, which it cannot.

    It is possible to use it as the background for an LED display, but these do not suffer from a lack of blackness, but the reflectivity of the LED layer and the top protective layer are the bigger problem. This new and super-black material would not help much, but only drive the production cost of the displays high up.

    It is useful not only for insides. It will also help with cooling in a vacuum system. For instance to get rid of the heat, which builds up inside satellites and to radiate the heat out into empty space.

    It could prove useful in a thermal solar power plant to produce even higher temperatures.

    It is possible the absorption spectrum of the material goes beyond the visible spectrum, or, that it can be modified to work in a different spectrum, and thereby be used for more than just optical systems.

    But it does not have to be used for high-tech applications only. Just put some pipes onto your roof, coat the pipes with this material and run water through them. You will get a lot more warm and hot water in your house without paying extra for it.

    Angel Merkel grew up in East Germany under a socialist regim where spying was a major tool in controlling the people. Back then when it had no computers and no computer networks did the government keep files on all their citizens, which tells a bit about the amount of espionage going on back then. The so called "Deutsche Democratische Republik" was not democratic at all with its single politcal party. Either you were a member of the party or you were not, and not being a member made you suspicious and a possible risk to the governement. It also did not have a free economy, but a centralised economy. It meant that if you wanted a car, of which there was only one brand available, you had to wait years to get one. The people of East Germany back then had to make the best of it and spying on one another was sadly a part of it. You could not say a bad word about the governemtn or the only political party (which basically meant the same people) without it having consequences for you. It could mean that the car you had ordered would get delayed by a few more years, or that you did not get one at all. If you were trying to build a house could this have meant that some basic building materials suddenly had become unavailable to you. And so on. So spying on oneanother and tipping off high ranking officials gave people power over each other. It is save to say that Angel Merkel knows quite well about the consequences of espionage from her childhood and her youth growing up under a socialist regim. I am not saying she is afraid of espionage, but rather is she an intelligent woman who can tell wrong from right and good from bad. She knows espionage can be good and as well as bad. A good spy is then one who uses his knowledge for good and who does not get caught, whereas a bad spy fails and is also the one who is more likely to get caught. With all that said, Angel Merkel will have done the US a favour by throwing out a bad spy. It will also help her in securing her own political position, because many Germans will still remember the ways of old East Germany. And personally will it give her a great relief to know that she is able to fight bad espionage between friendly nations.
