  1. Instruction set is no longer important on Why Can't Intel Kill x86? · · Score: 1

    Nowadays, the instruction set is just a front end and changing it won't do much in term of performance.
    I believe that the reason why x86 is so prevalent on PCs and ARM in mobile devices is mostly historical : Intel focuses on expensive, high performance CPUs and ARM on cheap, low power SoCs.

  6. Re:Blizzard did the same BS in Diablo 3 on EA Building Microtransactions Into All of Its Future Games · · Score: 1

    For Diablo III (softcore), I noticed just the opposite : on average, gear quickly lose value.
    This is understandable because the auction house, with its 15% commission makes a very efficient gold sink : if the prices get too high, more gold will get destroyed by this commission, but it won't be created any faster. It is effectively a negative feedback loop that stabilize the prices. In the last patch, the new actually useful crafting recipes added even more gold sinks. OTOH, once a good item enters the economy, it stays. And once people upgrade they are likely to sell their lesser items for cheap. And now these lesser items are actually quite rare and good enough to clear the game in its hardest difficulty setting.

  8. Games ! on Is the Wii U Already Dead? · · Score: 1

    Systems don't really matter, games do. When people buy a console it is usually to play specific games, sometimes just a single one.
    Whatever the age or the technology behind the console is, if there are great games on it, it will sell. It's that simple.

  10. Re:car 2 car comm = bad idea anyway on Carmakers Oppose Opening Up 5GHZ Spectrum Space For Unlicensed Wi-Fi · · Score: 1

    Yes, it could work. The key for this system to work is to make sure that to follow a car closely, you should check constantly (let's say within 10ms) that the next car is OK.
    A blowout doesn't stop a car instantly, in fact, few things can stop a car faster than breaking. In the event of a blowout, the computer can quickly notice that something went wrong and signal an emergency to break all the other cars behind it and those coming the opposite way. All cars will then start breaking at the same time, relying on their internal distance sensors and ABS like systems to release the breaks when the car behind it comes too close. Because the cars constantly check each other, a failure is unlikely.

    Self-driving cars certainly must adapt to radio interference and use all their senses but this is no reason to make one of these senses less reliable.
    For the same reason that even if we don't absolutely need break lights it is no reason to make them less reliable.

  12. Re:Large? on France Plans 20-Billion Euro National Broadband Plan · · Score: 1

    I don't know about Australia and Canada but French rural areas contain a large number of small villages (about 35000-40000). It results in a complex network of small roads and I believe it is much more difficult to connect than a few farms along a highway with huge fields in between.
    The disadvantages is not just the size (population density and area are somewhat average) but the fact that the population is more evenly spread out than in most other countries.

    Here is an example of what I'm talking about :

  13. Re:Carmack? on Carmack On VR Latency · · Score: 1

    IMHO, Megatexture style engines are the future. The reason is that we our eyes resolution is limited, there is a point where adding more detail is useless and we are close to this point right now. On the other hand, storage capacity and bandwidth continues to increase, making repeating textures less interesting.
    Also, RAGE is designed to run 60 fps on XBOX360 and PS3, as a result, a lot of compromises were made. It probably explains the mostly static environment.

    I was also a bit disappointed by RAGE but I don't understand how one can say it is 10 years out of date when it uses something that has never been done before in a commercial game engine.

  14. Re:Is It An Invention? on Do Patent Laws Really Protect Small Inventors? · · Score: 1

    If it isn't an invention worthy of a patent, I don't know what it is.
    The idea of tying a generator to a radio is the easy part, and like all big ideas, even earth-changing ones, it is not worthy of a patent. What deserves a patent is the hard work that transform an idea into a working prototype.
    Ok, you want to tie a generator to a radio : what kind of radio do you use, what gears, what materials, how does it hold together, how to get a steady voltage, etc... ? These are the questions an inventor must answer. And this is probably the reason why M.Baylis didn't get any royalties from the battery-based design : it is not the same invention even if the idea is the same.

  15. Re:No one wants a repairable tablet on Surface Pro: 'Virtually Unrepairable' · · Score: 1

    Yes, you sometimes need concessions. For example, sockets and slots take valuable space and may be points of failure, this is why I have no real problem when manufacturers decide to solder everything to the main board. Same thing for these fused digitizer/screens, it prevents dust and moisture from entering, which is a very good thing.
    But what is the reason behind glued batteries ? If the space inside a device is that well managed, the battery should have no room left to move around, meaning that glue is superfluous. Also, user replacable batteries are not just good for repairability. There is the ability to use spare batteries and a way to really turn off the device (by removing the battery).
    And what about the glued screen ? I'm sure a few screws would have greatly imporved repairability while sacrificing maybe a few milligrams of weight and a few micons in size. There are already more than 90 screws inside the device, Would that be that much of a problem to make some of these accessible from the outside and avoid a dangerous operation with the heatgun.

  16. Re:You know what I'd like to see? on Ask Slashdot: Why Is It So Hard To Make An Accurate Progress Bar? · · Score: 1

    I consider it to be in the "ugly tricks" category. Obviously, you don't want to straight up "kill -9" your program. If you put a "Cancel" button, you may want to do a little bit of cleanup afterwards.
    A little better way to do this is to create another process for the "uninterruptible" operation so that you can kill it and still retain control for the cleanup. You can also use signal handlers. Unfortunately, these solutions are not always portable or efficient, or they may simply conflict with the general API design.

  17. Re:You know what I'd like to see? on Ask Slashdot: Why Is It So Hard To Make An Accurate Progress Bar? · · Score: 1

    After a working progress bar the next hardest thing is probably the "Cancel" button.
    Like with the progress bar, it often requires handling deep inside the code. Sometimes even forcing the programmer to rewrite some standard API functions.
    A typical example is copying a file : many APIs provide a way to do it easily but no way to stop it once it is started. As a result many programmers prefer to wait until the operation is complete to effectively cancel the operation rather than rewriting the "copy" function or relying on ugly tricks.

  18. Re:So, video codecs are out of scope, but DRM isn' on W3C Declares DRM In-Scope For HTML · · Score: 1

    As evil as DRM is, the proposal is technically more "in scope" than video codecs.
    The reason why the video codec is considered out of scope is because there is no "best" choice and there is room for improvement (see : h.265, VP9). As for the "proprietary, controlled, patented standard", I believe you mean h.264 aka MPEG4-AVC. Well, sure, it is not free but technically, it is the best for now, plus it has very good hardware support. And we are not certain that WebM is really patent-free considering how close it is to h.264 in some areas. (more info : http://x264dev.multimedia.cx/archives/377).
    On the other hand, the proposed mechanism for DRM is much more abstract. It is just an entry point for the decoder to request a key. Nowhere a specific algorithm is mentioned. And the way to actually protect the content is totally out of scope.
