  1. Re:Pictures on Interpol Unscrambles Doctored Photo In Manhunt · · Score: 1

    Let's say you have a printed photo and then you set it on fire and burn it until it's ashes. Can you "do it backwards" and somehow get your picture back? It's no different. Yes it is. Burning the photo is actually destroying the image, because it's making it all one colour (black). Blurring an image in on computer, the way it is usually implemented, is actually a reversible operation. You can't get *all* the information back, because some information is lost due to limited colour resolution, but much of the information is still in the picture, it's just spread out. That's why on TV, when they obscure someone's face, they mash it to a 8x8 image, instead of blurring like they used to. Screen grab the blurred image and you can recover a pretty good image.

    It does seem, in this case, that the image was only a twist effect, and that there wasn't any separate blur added, though. Seems pretty retarded to post such an easy-to-unmunge image of yourself fsking a kid though.

    Actually I was employing the 'I Did Something That Looked Similar In A Java Applet, And It Worked Like This' approach to Discussing Things On Slashdot. Mine applied a blur (actually a square convolution kernel with side length max(image_width - distance(cur_pixel, center_pixel), 0), followed by a spiral effect that rotated by t * max(image_width/2 - distance(cur_pixel, center_pixel), 0) / image_width radians, if you want jargon). It was meant for links, to look like the swirly thing that the books in Myst do when you click on them. It worked quite well. :)

    Of course that was back in the heady days of "the more things that move or sparkle, the better" web design. :P I'll dig up the applet in question when I get home.

    Well, I'd guess the twirl is a convolution filter followed by a twist. If you can separate it out then you can reverse the twist, and then deconvolve the resulting blurred image, you get the original image. I'd guess. But it's been a while since I did computer vision, and it's probably more complex. :P

    "I think that quality was a true innovation on Blizzard's part. Nobody had done that before at that level of play. Because they did that, their game stood out night and day above everybody else's games. What's the biggest mistake? What everybody did without exception -- shoving it out the door. This quote just restored my faith in WAR. Finally someone gets it. Finally someone in charge of a game company actually understands what makes Blizzard games different. Sure, you can't polish a turd, but that doesn't mean don't polish. You have to start with a diamond, and then you'd better polish it to within an inch of its life, or that magic first impression won't be there.

    I haven't used amphetamines personally, nor have I spent time around users, so I'll defer to your knowledge on that. I may have been thinking of dexies - regardless, agreed that methamphetamines are generally bad.

    The statement regarding MDMA, on the other hand, I can back up. It's only addictive in the same way that a hug from your lover is addictive - there's enjoyment but not dependence. I took it at a variety of raves over about a year and a half, probably half a dozen times in total. At the time I was depressed and it helped me with that - I haven't touched it in a year and a half, and since I met my fiancee and got some naturally produced serotonin flowing, I haven't been remotely tempted. It's a place I'd go back to visit, maybe, someday, but there's no urgency about it. It's right about par with 'find a Sonic cartridge for my Sega Genesis' on my priority list. ;)

    Drugs are bad, because they cause physiological (chemical) dependence No. Physiologically addictive drugs are bad because they cause physical dependence. Most drugs are not physiologically addictive, and of those that are, often substantial exposure is required. Also, legal drugs are among the most physically addictive (nicotine, caffeine) and harmful (alcohol, nicotine again) of drugs. Obviously I'm not condoning opiates, crystal meth, cocaine etc. which are very physically addictive and physically harmful. I'm just pointing out that the amount of disinformation around is staggering, and that many banned substances are banned due to puritanical administrative agendas rather than real medical or societal concerns.

    Most designer or party drugs (speed, MDMA), and so called 'smart drugs' (see 'smart shops' or 'head shops'), are non-addictive. They are usually banned on a pretext of anecdotal evidence or a few cases of death or illness following use, which generally could have been avoided with proper precautions and quality control. For instance, Psilocybin mushrooms (as the GGP mentions) have been shown to produce religious experiences.

    As for designer drugs, from the wiki page on effects of MDMA:

    Comparison of the number of ecstasy pills estimated to be consumed in England and Wales per year compared to the number of deaths resulting from ecstasy use, suggests that the risk of death from taking ecstasy is around 1 death per 100,000 users per year. This is approximately the same risk of death as is associated with adverse drug reactions to estrogen-containing (combined) forms of hormonal contraception. You're about as likely to die from a weekend party pill as you are from your contraceptive pill.

    (Disclosure: I've used magic mushrooms several times (in places where doing so is legal), and found that they can be powerful tools of introspection, as well as delivering some amazing experiences.
