  1. Do they use stolen credit cards regularly? on UUNet Is The Number 1 Spam Host · · Score: 5, Insightful

    Do they use stolen credit cards regularly? I wouldn't think so. You can get away with spam a lot of the time without legal conseqences but credit card fraud is another matter. Wouldn't any spammer that did this sort of thing get caught fast? Or do they go through chained proxies to do it all and regularly get away with it?

  2. Pioneer 6 is 38 years old now! on Satellite Celebrates 20 Years Working in Orbit · · Score: 2, Informative

    NASA's Pioneer 6 was launched on December 16, 1965. It was contacted in December 2000, when it was 35 years old. NASA doesn maintain regular contact with it but it's quite possible it's still functional. It was designed for a six-month mission to study the solar wind, magnetic field and cosmic rays. It is in solar orbit at about 0.8 AU.

  3. Re:Spokes? on Saturn Rings But No Spokes · · Score: 1

    Same here. All I saw were little roughly circular blotches, but I don't see why those would be called spokes.

  4. Re:Are they interpolating between two cameras? on 3D Mars Scenes Recreated From Photos · · Score: 1

    You may have to make up detail even in this case. Imagine you have two photos of a fairly narrow slit. At the midpoint between these two photos an object can be seen through the slit, but from the viewpoints of the photos themselves this object cannot be seen. This sort of situation can happen with for example ground with lots of rocks on it.

  5. Are they interpolating between two cameras? on 3D Mars Scenes Recreated From Photos · · Score: 2, Informative
    The range of motion seems extremely small. Are they just interpolating views from between two cameras?

    This sort of thing isn't new. Panorama Tools has PTInterpolate, which given two images of the same scene taken from different viewpoints creates any intermediate view. I've never tried it but this makes me want to.

  6. SnapDV seems to suck on Cell Phone with Camera = Scanner · · Score: 2, Informative
    Thanks for pointing this out. I just downloaded it and tried it. Unfortunately it sucks. The end result was full of misalignments and other mess. I tried it using both edges and regions and both results were terrible. VideoBrush Panorama creates a perfect panorama from the very same pan.

    It also seems that it doesn't do a lot of the things that VideoBrush Panorama does. It doesn't blend images but just sticks them there. It can't make 360 degree panoramas, it can't output QuickTime VR, it can't capture video itself, you can't fix it's misalignments and you can't do any basic image processing on the panorama before saving. It looks more like an alpha or the result of some research in progress than a software product that's actually being sold!

  7. Primax Datapen on Cell Phone with Camera = Scanner · · Score: 1
    I remembered seeing reviews and ads for something like this a while ago. One such device is the Primax Datapen. It's one bit grayscale and it can scan characters up to 1 cm high.

    The ads were in Snglish speaking publications and of course it implied it works with this alphabet but perhaps there was also a Japanese version.

  8. Re:Virtual Wide Angle Lenses? on Cell Phone with Camera = Scanner · · Score: 1
    Well, you can take a bunch of images and when you get home connect them with something like REALVIZ Stitcher. That seems to be the best application for this sort of thing though it is pricey. It can do a good job even without a tripod but if there are nearby things in the photos you do need to be quite careful to hold the camera in the same position. The software has tools to cover up errors from movement or parallax.

    Note that this is a different thing from the one mentioned in the article. To do this you keep the camera at one point and rotate it, prefferably around the nodal point of the lens. To do the thing described in the article you keep it pointed in the same direction and at the same distance from the page and move it around.

    REALVIZ Stitcher and some other panorama programs can also stitch togeather images of a flat object, like the article describes, but you must make sure that the camera remains at the same distance from the page and pointed in the same direction. I think some sort of stand is required. Hopefully with this new software you can get good results without a stand.

  9. VideoBrush Whiteboard on Cell Phone with Camera = Scanner · · Score: 3, Interesting
    Has anyone ever used VideoBrush Whiteboard? I think it already did something like this. You could film a whiteboard in a zig-zag pattern and it would stitch togeather the video frames into a high-res image of the whiteboard.

    This software is from the mid to late 90s and unfortunately not available anymore. iPIX purchased the company and discontinued all of its products. There are a few links to buy it but they say it's unavailable and I haven't ever been able to find it on file sharing.

    Another interesting program they had is VideoBrush Panorama. It is can only stich vertical and horizontal pans (don't even try zig-zag). It's pretty cool to be able to get panoramas from video pans, and the software is very easy to use. There is no need for a tripod. You can get an evaluation copy here. This and a resource editor might come in handy if you want to use it.

  10. Re:Helping it spread... on Visual Autopsy Of An ATM Card Skimmer · · Score: 1
    get a grip.. security through obscurity isn't security.

    I don't think this is like that. For security purposes a photo of the outside of the device and the machine with the device on it is sufficient.

  11. Reliability issues??? on FCC: VoIP Providers Must Provide 911 Services · · Score: 4, Insightful
    The ordinary phone system is extremely reliable. The electrical system is somewhat less reliable. Personal computers, some comsumer grade router/gateway boxes and many broadband ISPs are way less reliable. I don't think that VoIP, which relies on all these things, is ready to be used for 911.

    If a VoIP provider doesn't have to offer 911 and it doesn't offer it then I hope it is immune from lawsuits regarding 911. People will also hopefully keep some other means of calling 911 then. However, if a VoIP provider offers 911 people might use that as their only means of calling for help in an emergency and if it doesn't work someone may die, there may be huge lawsuits, etc. I'm sure this will happen soon enough.

  12. Re:the outer outer planets... on Venus: The Forgotten Planet · · Score: 2, Informative

    Voyager 2 got to Neptune in about 12 years. Pluto was actually closer than Neptune during that time. I guess it could still have taken longer to get to Pluto because of the positions of other planets that you'd use for a gravity assist, but I really doubt it'd take an entire generation.

  13. What about Pluto? on Venus: The Forgotten Planet · · Score: 1

    What about Pluto? It's the only planet that has never been visited by probes. It would more appropriately be "the forgotten planet".

  14. Re:It seems people have been sued for this on Electromagnetic Emission Art · · Score: 5, Informative
    The time domain reflectometer (TDR) injects a signal into a wire and then gives you some info about reflections that happen. It essentially measures impedance along the line and so it will show anything inductive, resistive or capacitive on it.

    I'm sure a lot of people here have heard about TDRs being used to troubleshoot network cables.

    As for electric companies being called hydro, I'm in Canada (A former British colony and in the Commonwealth) and it's the same here. It really doesn't make that much sense anymore because most power comes from other sources.

  15. Neat, but people will still complain on Chicago Police Force Wins CIO Magazine Award · · Score: 1
    This sort of thing is nice to read for a change. It seems we usually just hear about such projects being way over budget, extremely late, horribly buggy or even given up on.

    I guess people will still complain though, this time about big brother type stuff.

  16. It seems people have been sued for this on Electromagnetic Emission Art · · Score: 4, Interesting
    A while ago I searched for info about this sort of thing online. It seems that farmers using fences or long wires to get power have been sued for it. I've even read about people who lived close to high power transmitters running fluorescent tubes from small antennas and being sued for it. This is mainly just from usenet posts but I feel there's enough info out there to show that at least some of this was real.

    I also remember one of my high school teachers talking about how he used to work for hydro and look for this sort of thing while flying in a helicopter and inspecting power lines.

    Really it shouldn't be that hard to find this sort of thing. You can just use a time domain reflectometer, and power companies have these for finding cable faults.

  17. They didn't just randomly delete stuff on Debugging The Spirit Rover · · Score: 4, Insightful
    From the article:

    Using the low- level commands, about a thousand files and their directories -- the leftovers from the initial launch load -- were removed.

    I think that means they deleted the useless stuff they wanted to delete anyways but didn't get to delete before the crash. I also remember news about science data from before the crash that was received after they got the rover working again.

    As for how critical it is, well yeah, it seems the rover didn't need the contents of the flash file system. The operating system and other software was in the same flash memory but I assume that any sane designer would put in some hardware write protect interlock that's not easy to defeat accidentally.

    I'm sure that many wanted to see the Windows source, mainly out of curiosity.

    It's useless for the vast majority but it's not totally useless. At least it can be used to find some security vulnerabilities. I'm sure there'll be worms based on it but I'm also sure that there will be some helpful anonymous e-mails and patches sent to Microsoft.

  21. Can they recreate the sound perfectly? on Computers Replace Musicians In West End Musical · · Score: 3, Interesting
    Can they recreate the sound perfectly? I doubt it. Wavetable synthesis generally doesn't involve recording every possible tone the instrument can play. Some tones are generated from others so it's not perfect. Hopefully this system uses a lot of samples.

    I'm also pretty sure that a musician playing the actual instrument can change more parameters than you can change on a synthesizer simulating that.

    Even if you had a perfect recording of sound you wouldn't have the same radiation pattern from your speakers as from real instruments. I'm sure that using this you can tell if it's a live orchestra or a bunch of speakers.

  22. You get carbon dioxide. on Ethanol to Hydrogen Reactor Developed · · Score: 4, Informative
    From http://www.nature.com/nsu/040209/040209-13.html:

    The reactor pushes a mixture of watery ethanol and air over a rhodium-based catalyst heated to about 700 ?C. It takes only five seconds to start up, and produces a steady stream of hydrogen and carbon dioxide with very few other waste products.

  23. It'll be denatured on Ethanol to Hydrogen Reactor Developed · · Score: 1
    It'd almost certainly be denatured. This means it'll have some toxic stuff in it that makes it undrinkable. Perhaps it'll be methanol, which is toxic to the optic nerve and causes blindness.

    So people who drink it will get sick maybe go blind and perhaps die. Most people would learn not to drink it soon enough. As for the rest... well, have you ever heard about kids sniffing gasoline?
