    Not even your idyllic hunter-gatherer is stupid, though. They quickly learned to domesticate other animals, and use dogs to help them hunt. If dogs got killed in the hunt, well, it wasn't as big a loss to them. They didn't insist on doing every last thing by themselves.

    I think Slashdot can comprehend better if the proposition is put another way. We probably all have had managers who insist on travelling great distances to meet a client "face to face" to take care of something a phone call could have. Sending a human to do what a robot can is a similar waste of resources.

    I don't think humans should stop going to space entirely. However, I don't think we should risk human lives pointlessly either. Let's exhaust what the robots can do for us before we put ourselves in danger.

    JPEG works on 16x16 pixel blocks at a time. This means that you generate 16x16 tiles and see if they can compress to the same portion of the JPEG image in question. In other words, for every 16x16 block you have to generate 16*16*(2^24) distinct images and compress them. That's about 4 billion (2^32) distinct images, which should be roughly equivalent to compressing 1.4 million 1024x768 JPEG images (3072 blocks per image). With 30 fps real time MJPEG compressors, that should take about 13 hours to compress.

    To prove that the evidence was not doctored, a full 1024x768 image would take about 1,664 days (about 4.7 years) to complete at 30 fps. The good news is that the task is entirely parallelizable, so fifty such encoders would find the complete set of originals in just over a month.

    So no, nothing astronomical as far as I can see.

    Somebody might want to defame somebody they don't like (like the faked picture of John Kerry standing next to Jane Fonda at an anti-war rally) or manipulate the public into supporting some cause that they otherwise wouldn't accept.

    In such cases, the damage is almost always done at the point of initial publication, and no amount of proof matters. A significant percentage of US citizens still believe that Saddam Hussein had something to do with 9/11, and that didn't even involve a sensational doctored photograph. All the technology available is not likely to help this sort of thing, unfortunately.

    It's as simple as that is it? Have you worked on an IT support team? I thank God I'm not doing that thankless job anymore for users who see only their needs and no one elses.

    What I meant by "simple" was that it's simple to see what must be accomplished under a centralized IT policy: the organization must provide prompt service to the folks who no longer have the power to fix anything themselves.

    Exactly. You can view the JPEG compression process as mapping a large potential set of originals to one single JPEG image. However, if you can prove that you can generate the exhaustive set of originals (no other original can result in the JPEG in question), and that none of the originals pass the authenticity test, then you've proven that the JPEG could not have been genuine.

    There are entirely valid reasons to use multiple compression engines. For instance you might do your editing in one program, and then optimize the image in another.

    Sure. Proving that multiple encoders went through the image doesn't prove that you doctored the image. The problem is that it's generally your responsibility to prove that you didn't doctor it. If a trusted algorithm cannot certify your final image as genuine (whether due to "valid reasons" or malice), then the image may not be admissible in court at all.

    Compress your JPEG with three different encoders at subsequently lower quality settings until you reach the quality setting (and file size) you're looking for, and the artifacting will be effectively untracable.

    In a modern court, the defense doesn't have to prove that you've doctored the picture. If they can prove that you've run the image through three different encoders (rather than coming straight from the digital camera), they will likely establish reasonable doubt that the image is genuine.

    how can you tell what is a result of manipulation versus what is an artifact of compression and or digitization?

    Just a wild idea off the top of my head... while JPEG image compression is a lossy process, it's still a mathematically reproducible process. It might therefore be possible to exhaustively generate the set of originals that could be compressed to the image in question*. If you then apply the detection algorithm to the originals, none of them may pass and you'll still have a valid conclusion.

    * Made easier if you know the precise implementation (i.e., which digital camera, which version of Photoshop, etc.) that created the JPEG.

    the research that I read made it seems as if we are unique to the point where having billions of galaxys would make little differnce.

    No, what we lack is precise knowledge that the earth is special. That is, we don't know the probability by which a planet has a big moon, or that it is near enough a star to sustain life. We don't know the very parameters of life, except that it exists on earth in great varieties.

    Absent this knowledge, it is incorrect to assume that the earth is special, any more than a lottery winner should see herself as (too) special. If you only know of one lottery winner, then you'll be misled as to how often somebody wins the lottery if you try to extrapolate based on that ignorance.

    The correct approach is to assume that we are one instance of random behavior, that the earth just happened to be so far from the sun, that we just happened to have a big moon, that we just happened to not have collided (yet) with another big object. We are likely a very special planet, but we really have very little clue whether we are special enough to claim exclusivity.

    Once you accept this randomness assumption, then the probability of life (and therefore intelligent life) on another planet is entirely a matter of how many planets there are out there. The more, the likelier.

    Remember that if you're a one-in-a-million kind of guy, there are more than 1,000 people in China alone just like you.

    However, if it's available only illegally, then a fan who wants to hear the album has no choice but to break the law. Having acquired the music, the fan will be less likely to pay for it when it is released legally.

    Once you understand that this is not meant for the people who never would've paid for it, the logic becomes quite simple.

    When you rent a car at the airport, you sign some papers, and they tell you where the car is. The key is usually in the car. Without that agreement on paper, you'd be stealing their car. Presumably, for a suitable sum of money, you can persuade the agent to let you use a car whenever you like.

    The difference in this case is that one of the parties cannot plausibly refuse to make a deal. For example, if you put a gun to the rental agent's head, then he'd sign any paper you want. Similarly, not shipping Windows is simply not an option for these Japanese companies, who are being bullied into signing away their intellectual properties. It's not a legal contract not because of the "car", but because of the uneven negotiating positions.

    Two, usability is not a static thing. We have a computer userbase that is significantly savvier than the guy who walked into a computer store demanding a "VisiCalc" not knowing he needed a computer for it. This means they recognize common widgets like scrollbars, drop-down menus, buttons, checkboxes, and others, no matter what shape they're in. With the popularity of $200 game consoles, a lot of people have prior experience dealing with customized (that is, "weird") computer UI.

    Three, there's another aspect of usability that isn't static. Users learn. While you can compare the efficiency of first-time computer users introduced to a Mac or to Windows or to KDE, that's a pretty pointless benchmark.
