  1. I would love to ... on eBooks - What's Holding You Back? · · Score: 1

    As someone about to head off on a 6 month trip around asia, I would love to have a functioning e-book to take along. Currently I have a pile of travel books at home a bit over a foot high (borrowed from friends) - I would love to take them with me, but just dont have the space in my luggage. I would also happily read some 15 novels or so during my trip - again, no space. So I am kind of stuck with a single travel book which covers all of asia without any detail, and a hope that I will be able to find a good english novel somewhere in a village in northern Burma.

    An ebook would be great - as many books as I want to take in a package smaller than my current novel; easy searching in the travel book, preferrably with hyperlinks.

    Whats stopping me - battery power, and a lack of titles to choose from. Once ebooks supported a huge range of titles, each at a reasonable price (ie much cheaper than the dead tree variety, because I assume I wont be able to ever transfer it to another reader) and once the battery life issue is solved (ie no backlight!) then I would jump in.

  2. Re:Evidence on Film Studios Sue Samsung Over DVD players · · Score: 1

    The main reason for region codes is to increase profits by ripping us off. They prevent people importing DVDs (legally!) from other countries where they are cheaper, and re-selling them in other countries where they are more expensive.

    If it was really just for the staggered movie releases then why is it that DVD releases of old movies are always region coded? Why is Matrix region coded - they had a simultaneous worldwide release!

    It is also cr&* that the region codes are for copy protection - you dont need to decrypt the disk to copy it.

    Conclusion - region codes are there so that studios can have different prices in different countries. Pure profit, with the customers losing out.

  3. Re:sounds good in theory... on Unlimited Legal Music Downloads for $3.95 a Month? · · Score: 4, Interesting

    Nielsen Soundscan already tracks paid downloads. It wouldn't be hard for them to track popularity of P2P downloads too.

    However what happens to the tracking if the artists themselves decide to boost their income by having bots download their songs as often as possible?

    Tracking P2P downloads is probably simple and accurate as long as noone is profiting directly from the results. As soon as an individuals salary is completely dependant on these figures then I think it will get much more difficult to ensure the correctness of the results - it is too easy for people to influence.

    No, a decade or two ago people like me were saying that nothing can go faster than the speed of light, and guess what - it is still true. This is not a question of whether they can improve the technology, it is limited by the laws of physics.

    If the idea has no practical application, why are you complaining about a specific implementation of it?
    umm, I guess it was to point out that a $10000, 4lb/3kg, 0.08 megapixel camera is not very practical. You planning on buying one?

    Another ten years of improvement and suddenly we have 16 megapixel images using this technology
    NO, we are not going to have 16 megapixel versions of this. The laws of physics dont change very quickly, the wavelength of visible light is pretty stable and as a result, the minimum size of pixels are not going to get much smaller than they already are in mobile phones! This technology cant go beyond 1 megapixel, not because we dont have the technology yet but because the laws of physics will limit this.

    Now, what exactly were your qualifications? They certainly dont include anything about physics, electronics or image sensor design! So shut up and let people who actually know about this technology write something relevant about it.

  6. Re:You don't really lose resolution on Refocusable Plenoptic Light-Field Photography · · Score: 1

    Sure its fair to say you lose resolution - the output image of your 16MP camera is 0.08MP. How do you want to pass this off as "no loss of resolution???"

    Maybe you can reduce the size of the pixels without increasing the noise in the final image, but be warned - as these pixels get noisy, the quality of your refocusing will drop. There is always a cost of reducing pixel size.

    It also doesnt work to make really tiny pixels, you basically cant go below 2umx2um for a pixel, otherwise the pixel size is too close to the wavelength of light (0.7um) and then they stop working.
    A 12x12 array of 2umx2um pixels - thats BIG and physics will stop you getting them any smaller ... inside a mobile phone you wont get more than 0.025 megapixels!! - useless! In a big expensive 35mm camera, you wont even get 2MP - who is going to pay $5000 for a 1.5MP camera?

  7. Idea has no practical application! on Refocusable Plenoptic Light-Field Photography · · Score: 3, Insightful

    I saw this article about a week back. I am quite sure that this will never see a practical application ... They take a 16MP input image to produce a 0.08MP output image!!! They are using a $15000 camera system to produce images one quarter the size of VGA!!! Say what you want, but there are better ways to improve DOF.

    They reduce resolution by a factor of 180, but only improve depth-of-field by a factor 7. This is particularly silly because the only reason they have a bad depth-of-field is because they are using a huge expensive sensor. If they would switch to a small cheap sensor like you find in any cheap digicam (1/1.8"), they would get the same improvement, and save $14800.

    The light-performace of this small sensor would be just as good as their large one - if you use the same huge pixels that they do (to produce a 0.08MP image), you will get the same low light performance.

    Hiding encrypted data on a computer is actually very difficult - Encrypted data looks like random bytes. To find it, just search for files (or disk sectors) that are uncompressible ... If its not a .zip, .rar or .bz2 then most likely, its been encrypted.

  10. Learnings from the Competition ... on 18th International Obfuscated C Code Contest Opens · · Score: 3, Insightful

    • To show the importance of programming style, in an ironic way.
    • To stress C compilers with unusual code.
    • To illustrate some of the subtleties of the C language.
    • To provide a safe forum for poor C code. :-)

    They certainly achieve their goal of showing how bad caode can be and also of providing a safe forum for amazing C code.
    I have also learnt much better how to program in C, even for unobfuscated code. There is nothing like going through some of these entries to understand much better how the preprocessor works, and how compilers react to differrent constructs.
    So, the only goal left is that of stressing the C compilers ... does anyone have some good examples of bugs found *and later fixed* in c compilers due to this competition? There are certainly enough evidence of the compilers being crashed, but I wonder if anything positive has come out of it.

    This is not true. As covered above, if you implement your own idea and it happens to be an idea that was earlier, independantly patented then you are infringing it. Separate development offers you no protection.

    The reason why you should never look through patent databases is that if you know that a patent exists and then go ahead and infringe it then you are liable for much higher damages than if you did it without knowing about the patent at all.

  15. How do I know? on Nokia calls Wireless Warchalkers 'Thieves' · · Score: 1

    Firstly, lets make one thing clear - Warchalking itself is not theft!! Making unauthorised use of a
    wireless network could possibly be deemed as theft, but I would disagree.

    Consider as a comparison a company which has a drinking fountain in their entrance hall. Is it theft for me to drink from this fountain? The company could probably claim that I was not authorised to consume their water and that this
    was clearly a case of theft! They would probably be right.

    Dont forget that a lot of places that have open wireless networks have specifically left them open to everyone as a public service, eg cafe's, private people etc. There is no way for the person to know what the intention is of the person providing this service.

    Therefore, i would say that using a companies network should be prosecuted as theft if it was VERY clearly announced that use of this network was not allowed. If this is not made clear then it is unreasonable to expect the user to know the expectations of the owner of the network.

  18. Moving into an even more grey area ... on The Abandonware Question · · Score: 2, Interesting

    I remember at least a year ago I was looking through my collection of CD's and came across my old Civ2 CD (checking copyright on CD ... from 1996). So I thought - great, I would love to play this again. The install went fine, and I was up and playing quite quickly (enjoying the questions about whether I want to enable the tiny tiny videos/heralds as they need 16MB of memory !!?!?!)

    Then I fairly quickly realised that the first releases of Civ2 were quite buggy / unfriendly, but that these had been fixed in a series of patches (I think 14 of them in the end). When I first bought the game it was no problem to download the patches from the microprose site, but there was no chance of downloading it from infogrames (or whoever happened to own it then). So I searched around and found the patch on some download site.

    Now, The patch is also protected by copyright, just as much as any abandonware game is protected. So, do those companies who oppose abandonware so vigorously also oppose this distribution of this patch? I think that to claim that distribution of a patch for an old game is just as bad as distributing the latest release on some warez site is just stupid. Hopefully these companies would say the same thing, but im not so sure...

    (Having just checked the infogrames site, I can see that they now have the patch available for download! Full marks to infogrames for still supporting the game!)

  19. Re:On the reasoning for freely taking it on The Abandonware Question · · Score: 3, Interesting

    Be careful about the question that you ask ...

    I think the question should not be whether people would be willing to pay for the software if it was still available for sale (probably not, but depends on the price - at $2 there is a good chance, at $39.95 - not likely).

    What we need to ask is whether Abandonware supporters would happily remove titles from their sites if a company started selling the game again. Here I think the sites would happily remove them - The titles are available, no need for the abandonware site to distribute it.

    As long as this is true, then I think that abandonware sites are morally correct, although they are almost certainly breaking the letter of the law.
