  1. The efficiency of throttling on Catching Spam by Looking at Traffic, Not Content · · Score: 1

    I guess it makes sense to throttle the connection: it will do no harm to legitimate email (I mean, it's not like it would really matter if the delivery takes 10 seconds or 50 seconds), but would seriously hamper the sending of millions of messages. That way, it wouldn't really matter if it gets some false positives, unlike with methods where the message is removed if it's deemed spam.

    Sorry to rain on your parade, but according to this page, the volume of blood in an elephant is: about 9.5% to 10% of body weight. Using this page to get an estimate of an elephant's mass, we learn that they are on average 5000kg. So they contain roughly 500 liters of blood.

    As per my calculations in another post, we can fit a library of congress into 0.0191739611 liters of blood. So we can fit roughly 26,000 libraries of congress into 500 liters of blood.
    (500 liters) / (0.0191739611 liters) = 26 077.0321

    We have to take into consideration that I used an estimate of 20 terabytes for the LoC, if we half the number, then we get the figure 13,000 LoCs per elephant, which is already closer to your estimations. If we furthermore use a lower figure of 3500kg for the weight of an elephant, and consider that it's blood volume is 9.5% of it's weight, that yields 3 500 * (9.5%) = 332.5 liters of blood.

    Enter into google: ((332.5 liters) / (0.0191739611 liters))/2
    (remember, we divide by two because your estimate was 10 terabytes per LoC, whereas my earlier results went with 20 terabytes) and the result is
    ((332.5 liters) / (0.0191739611 liters)) / 2 = 8 670.61319

    In other words, I'd say we can fit between 8670 and 26,000 Libraries of Congress in an elephant. I guess your results fit within the margins of error: Elephantology (much less LibraryOfCongressology) is not an exact science.

    Stop opressing me, I can post where ever I wanna!

    But seriously, using the estimate from wikipedia: "It is estimated that the print holdings of the Library of Congress would, if digitized and stored as plain text, constitute 17 to 20 terabytes of information", we can use google to calculate how many such chips would be required to store the US Library of Congress:

    Enter into google: (20 terabytes) / (160 kilobytes) = 134 217 728

    Now, with some reasearch into White Blood Cells, we learn that a normal human has between 7000 and 25,000 white blood cells in a drop of blood. So going with a conservative estimate of 10,000 white blood cells per a drop of blood, we could store the Library of Congress in
    134 217 728 / 10 000 = 13 421.7728 drops of blood.

    That's not very accurate, let's try to get a better estimate. Wikipedia to the resque:

    There are normally between 4×10^9 and 1.1×10^10 white blood cells in a litre of healthy adult blood.

    Again, with a conservative estimate of 7 x 10^9 white blood cells per liter, we get
    134 217 728 / (7 * (10^9)) = 0.0191739611

    Entering into google 0.0191739611 liter to centiliter, we get
    0.0191739611 liter = 1.91739611 centiliter

    In other words, storing the whole Library of Congress using these chips would take about half a shotglass of blood.

  4. Re:But in the US, we get the "PERFORM Act" on EU Countries Call Out iTunes DRM · · Score: 1

    Here's a statement from the Finnish Bureau of Consumer Rights. I don't think it says anything about licensing DRM (although it doesn't demand a ban either, but just that consumers have the rights that they are entitled to). I translated quickly and without checking for the exact terminology, you should get the point.

    Demand for iTunes to fix it's end user agreement

    The consumerombudsmen of Finland and Norway together with the consumer organizations of France and Germany make a joint demant to the iTunes Music Store to fix it's end user agreement to be more consumer friendly. Each country has sent a letter to the iTunes with the required changes.

    The central problem has been, that song files bought from iTunes can only be played on certain machines. In Finland, it is held that the consumer should be able to pick the device he uses to listen to songs he bought online. Therefore, any license agreement that prevent this, or make it unnecessarily complicated, have to be removed.

    In the talks has been an option for iTunes to notify their users of the option to circumvent technical limitations by first burning the songs to a cd and copying the songs from the disc to some other mp3 player. This is not a good enough option in the long term. It is suggested that the company think of another solution for the songs bought from iTunes to be compatible with every device. Development in this regard is expected by the end of September 2007.

    iTunes has to also change a section of it's contract terms in which it reserves the right to one-sidedly change the terms of use of the service. A company cannot without limits change an already entered contract. In addition, iTunes needs to change it's terms of contract so that the risk of a harm that can fall upon the music files, or harms caused by them falls with greater equality upon the company and the client.

    The consumer ombudsmen of Finland and Norway and the consumer organizations of France and Germany have also noted that iTunes mentions in it's contract that it applies the law of England for the contracts. The consumer clients of iTunes have to have the right to appeal on the laws of their home country.

    Each of the nordic consumer ombudsmen and the consumer organizations of France and Germany have during the year 2006 negotiated with iTunes. The countries are also working in collaboration to improve the rights of the european consumer.

    The compatibility of songs with different devices and the overall right of consumers to utilize music downloaded from the net with more flexibility are the key, if the goal is to further the the legal market of music downloads. The iTunes case is also anexample to other companies in the business that compatibility is important for the consumers and companies should note it in their strategies.

    One of the things I guess is problematic is that you can't exactly call 911 and send them a video clip at the same time with today's phones - most seem to have them mutually exclusive.
    In Finland, I think every operator already offers video calls, and probably most of the 3G phones at least have the functionality. I'd be surprised if e.g. Nokia was stripping the feature out of the phones in the US, I'd bet it was a limitation of the network (operators) if that's not available.
  8. Re:WTF? on FBI Arrests Neteller Execs · · Score: 5, Informative

    Neteller is not a casino. It's an eWallet company that (as far as I understand) was not breaking any laws before the Unlawful Internet Gambling Enforcement Act (UIGEA) passed. It is listed in the London Stock Exchange.

    The current issue (arrests of Neteller founders) is not really about gambling, they are not charged under the UIGEA. The charges are for money laundering. A quote from the press release:

    "Stephen Lawrence and John David Lefebvre were arrested in connection with the creation and operation of payment services that faciliated the transfer of billions of dollars of illegal gambling proceeds from United States citizens. [...] This prosecution is part of the United States Department of Justice's effort to combat unlawful internet gambling through, among other things, the implementation of the federal anti-money laundering statute."

    I think the charges are bull, but at least they weren't stupid enough to go with the UIGEA charges. Also I think parent poster has his head up his ass. According to everyone but the US, Neteller was doing legitimate business (unlike Kazaa or AllOfMp3).

    You may be right, I may have been hasty. Then again, people who I know don't get a lot of malware in the first place. But the point still stands, that you hear about malware pulling all kinds of crap daily, but never about this kind of problems -- except when people are charged with stuff. It'd give the argument much more relevance, if I ever heard of one innocent case (say a slashdotter's family member) that had some illegal files placed on their computers.

    Then again, people might not want to tell if they found something illegal in their parents computer, just clean it up and keep their mouth shut. So, if anyone has ever run into this, post AC and let us know!

  13. Is there really malware that does this? on Fighting Porn Vs. Ruining Innocent Lives · · Score: 1

    The part I don't get about this kind of issues is that the explanation is always the same: there was spyware (or whatever) on his computer, so he didn't do it! How do you make that mental leap? Is there solid evidence behind it? Are there really trojans that litter a computer with child pr0n? Or is it just about deniability?

    Sure it's enough to give the guy the benefit of the doubt, but how common is it to get your computer infected with child pr0on or other unacceptable material? I don't know anyone who this would've happened to. Are they just too unlucky to both get infected with the brand of malware that spreads that kind of material, and get caught about it before figuring it out themselves?

    I mean, if you compare it to the doping scandals, we hear the standard lines again and again. "I got cold and took an aspirin, the growth hormone must've come from there". Maybe I'm just a bit cynical.

    Are you kidding me? Weather is the perfect measurement target for Celsius. Above 0 and generally you won't have frozen roads or snow (you have to take care when it gets close to 0, though). Below 0 and you can be sure it's snow and ice you need to look out for, not rain.

    When used for daily weather talk, one celsius is more than enough. I probably couldn't tell the difference in weather in changes that are less than ~3 celsius. Generally over 20 celsius (at least for us living up north, in Finland) is nice and warm. Over 25 is very warm and over 30 is too hot for us.

    Frankly, I couldn't live in a world where the water doesn't freeze at 0 and boil at 100. I guess it's no more use for me to defend celsius, than you to defent fahrenheit: we're the product of our native systems. But your argument is certainly one of the worse ones I've heard for fahrenheit ;-)

If the gulf stream, which warms us up would stop as a result of the changes in the Great Conveyor Belt, we'd be pretty much screwed.
