  3. Re:Misrepresentation of Carmack's "rant" on Why You Should Use OpenGL and Not DirectX · · Score: 1

    Yes, the mode was called Immediate Mode in older DirectX versions, and without question it was slower than OpenGL's method of doing the same thing.

    OpenGL's problem back then was that it could *only* be programmed in this same way.

    Modern graphics cards greatly benefit from queuing many rendering commands and re-ordering them to better exploit the specifics of the hardware, and in DirectX land this is done through Retained Mode.

    Retained Mode ended up stomping all over OpenGL in performance because Retained Mode left many of these very high level optimizations up to the driver developer, instead of requiring that the game developer do that optimization work.

    In theory that old OpenGL was just as good as DirectX Retained Mode, because the game author could simply wrap up OpenGL and provide his own Retained Mode simulation complete with all the same optimizations, but in actual practice it became too much effort to get there.
    OpenGL started out great, but its stagnation left it behind in the dust on the Windows end. Its too late now. The best they can do is catch up, but they actually arent doing a very good job of it.

    OpenGL is THE cross-platform 3d rendering API, but consumers just dont give a shit what API the developer used or how many other platforms the developer can market too. They only care about the platform that they have in front of them.

    You are wrong. If it has a model for Light On, and another for Microwave On, then the model Light And Microwave On can be easily derived, and detecting which context things happen to be in isnt as hard you are making it out to be. On top of it all, the models can be learned adaptively. There are plenty of machine learning techniques that are quite successful.

    And above all else, this presumes that such fields represent a problem that even needs to be overcome. Just because they once were doesnt mean they still are. I think that you are just nay-saying.

    You're taking a series of point samples in an environment that changes unpredictably. That's a hell of a "modelling problem".

    Unpredictable doesnt mean random tho. That 'fridge isnt randomly jumping around the room. The compressor is either on or off. The light in the room is either on or off. The microwave (probably the biggest source in your home) is either on or off. Presumably it should be trivial to detect the context of the immediate situation.. "seen this before"

  11. Re:Electromagnetic tracking? on Razer, Valve, and Sixense Working On Motion Control For PC Games · · Score: 1

    Changing fields is also a modeling problem, tho. As far as the # of samples needed to average things out well.. surely that isnt a technical problem but instead just some sort of economic tradeoff. Do you want thousands of samples per second? How about millions? Pick one. Both are doable.

  12. Re:Gaming is best when it is consistent on Razer, Valve, and Sixense Working On Motion Control For PC Games · · Score: 1

    One of the problems with PC gaming is that the experience is never delivered in a consistent manner.

    Thats not precisely true tho. Not all games target the next generation hardware. Some games target several generations back providing a fairly consistent experience, and one of these in particular became the most successful MMO ever. I've never played it, but I am sure the console boys are extremely jealous of the massive cash cow that it WOW.

    The breakthrough, if any, probably isnt the detection equipment. External fields isnt an obstacle, its a modeling problem that can be dealt with. The model just needs to include them, so in the end its a signal analysis problem (learning the proper model for the individual installation)

    Indirectly referencing the famous works of others isn't something you need their permission for.

    Are you sure?

    My thinking on the matter is that this family SHOULD go through the motions of trying to protect themselves even if it is fruitless, because if the shit ever hits the fan in regards to the the Android and Nexus products (for example, their batteries start blowing up) they can then distance themselves quite succinctly: "We tried to stop them from using these names. We have nothing to do with the products that killed people."

  15. Re:2010 on 2010 Bug Plagues Germany · · Score: 1

    You havent said anything that I didnt address. Even if you fully leverage standard libraries, you still have to call those libraries correctly. There isnt a ConvertDate(string) function that magically figures out what format the date is in.

    Heres an example: "1/8/10"

    Is that January 8th 2010? August 1st 2010?

    It could be August 10th 2001, or even October 8th 2001.

    Thats 4 different dates that all match a format used somewhere in the world, and I havent even gotten the exotic shit yet.

    There is plenty of room for complexity no matter how "solved" you claim this problem is. You are arguing from a position of not having to actually deal with the problem robustly in a live mission critical scenario which just makes you an arm-chair hack spitting opinions that arent relevant.

    If you had explored deeper, you would have discovered (after clicking on the primality test link) that "Most popular primality tests are probabilistic tests. These tests use, apart from the tested number n, some other numbers a which are chosen at random from some sample space; the usual randomized primality tests never report a prime number as composite, but it is possible for a composite number to be reported as prime."

  18. Re:Can someone explain this to me? on Factorization of a 768-Bit RSA Modulus · · Score: 4, Informative

    Just to be accurate, I do not believe that in RSA you pick two primes but instead pick two values that are at least psuedoprime. Testing large numbers for primality is time consuming, but quick tests can eliminate nearly all composite numbers. The set of numbers that pass these quick tests but are not prime are called psuedoprimes, and are still usually pretty hard to factor.

    That whole 'put something into orbit' crap is old news. Very old news. As in over 20 years. Thats 2 decades. How old were you when Arianespace was started (thats 1980.)

    I think most of the time they are building their own conversions to date formats because they have to. Those standard libraries are great when the date is in a standard format, but multinationals deal with nearly every variation of date encoding known to man.

    1-digit years, 2-digit years, 4-digits years, month-before-day, month-after-day, year-first, year-last, decimal-seperators, slash-seperators, dhash-seperators, space-seperators, a-mix-of-seperators, without-day-of-week, with-day-of-week, with-day-of-week-abbreviated, without-english-month, with-english-month, with-month-abbreviation, and all words in many languages.. and different variations on abbreviations..

    Even if these guys leverage the standard libraries as much as they can, its still non-trivial to do it correctly. Multinationals arent dealing with data in a single format.
