  1. Here is the asnwer on Does the World Need Binary XML? · · Score: 0

    The answer to your question posted on slashdot on January 14 2005 written in plain English, containig 31 letters and no binary data or images and entitled "Does the World Need Binary XML?" is given to you after long deliberations and consultations with higher authorities and spelled in plain English as "Yes"!

  2. Re:Listen, young one... on Hardcore Java · · Score: 0

    I ment swapping primitive types. Surely one can wrap them in a class in Java and do similar things, but it cost performance and memory...

  3. Re:Listen, young one... on Hardcore Java · · Score: 0

    To clarify the difference between pointers and references can you write swap(a,b) function in Java that swaps a and b?:

    int a=3; int b=5; swap(a,b); // a=5, b=3 now

    It is easy to do with pointers in C/C++:
    void swap(int* aPtr, int* bPtr) {
    int tmp = *aPtr;
    *aPtr = *bPtr;
    *bPtr = tmp;
    }

    but impossible with references in Java.

  5. Statistical analysis on Science of the coin-toss: Bias in Heads-or-Tails · · Score: 0

    Since only two stanford researchers tossed the coin their experiment is intrinsically biased. Unbiased statistical analysis would require hundreds of stanford statistitians to toss the coin...

  6. Re:Let's hope its just software on Spirit Rover Communications Error · · Score: 0

    Some small set of telemetry data is the most obvious signal any spacecraft should send by default - such as power system and antennas status, sensors etc.

    I don't buy that "NASA says it has been unable to get significant data back from the Mars Spirit rover for 24 hours" - no data at all or some telemetry data that already indicate what is wrong with the rover and just hiding it from the public.

    Also why they are so scary of rebooting it - at least this situation should of been designed into the rover and thought of many times before.

    Can anybody explain how reboot works remotely on rover? It is not one processor, isn't it?!

  7. Re:ESA is not very clever. on News from Mars · · Score: 0

    "If you fly lower, you'll make more orbits per day" not really significant effect. If apply Kepler's law (1619) - "The squares of the periods ... are proportional to the cubes of semimajor axes" - lowering the orbiter by 300km over Mars which has polar radius 3397km will make only ~(300/3397)^3/2 ~15% more orbits per day... at the same time risking to hit the surface.

    No, humans actually have very slow cpu inside their had - it will take you at least a second to read this post...

    It is very specialized one though. I am not sure that term CPU is applicable at all - you can train human to multiply large numbers and develop cpu-like abilities but it will be damn slow.

  10. How relevant top500 list to center performance?! on Linux Clusters Finally Break the TeraFLOP barrier · · Score: 0

    The top500 list was made by running the benchmark that solves a dense system of linear equations. Though this test can be relevant for the centers like #1 "Earth Simulator Center", #2 #3 Los Alamos and #4 #5 Lawrence labs - they are doing exactly that - who can tell me how relevant it is for Charles Schwab, Verizon, AT&T and Bell South ?!!! These guys are just running portals accessing huge databases, aren't they?

    It seems that the test is self-serving: the Earth Center is doing complex simulations - and it is #1 on the test that is designed exactly for that.

    Imagine different computer center - millions of clients are making requests for specific data or knowledge that requires complex data search and sometime small computations. What would be relevant is a test that measures how many simultaneous requests the center can handle (in the millions per second) and latency for each such request (in milliseconds). I guess that the Earth Center, or national lab performance score will be much worse.

    So I wonder how relevant top500 list is to the real power of a cumputer cluster that people need?

  11. Re:Poincare Conjecture on A (Correct) Poincare Proof!? · · Score: 0

    It is intresting to note that Nikitin's paper has no reference of Dunwoody work at all, most references are dated to 1920s-1960s. Is it just my observation or general feeling about the spirit in the field of mathematics? If so it is not surprizing that Noebel has not mentioned mathematitians in his will and we don't have Noebel Prize in Mathematics. So, who got $1M prize or this publication @slashdot is just marketing campain with the goal of getting one?

  12. Re:Spammers are middlemen on Meet the Spammers · · Score: 0

    The point is not who is the easy target. Using your analogy how can you go after the hitman if all hitmen are employed by police? It would be so easy to to stop spammers - just fine them 1 cent for any objected unsolicited mail - one that people report as spam to their ISP... If somebody writes 100 unsolicited emails asking about job interview - potential liability is $1; for aspammer with $1 billion emails liability would be in the $100k range and make it unprofitable. Why then there is no legislation like that?!

  13. Spammers are middlemen on Meet the Spammers · · Score: 0

    To my view spammers are just middlemen. Companies that hire them are real cause of spam. And any legislation would be to go against their interests - isn't that obvious? This is why your list of guidelines that you propose will never be the law unless there is another powerful interests like AOL or like that will lobby for them. Money is the law. Spam kills the internet.

    Hmmm... Video games have the same relationship to AI as any game - zero. Good games put you in a new situtation that you would never experience in real life - sort of what if situations. Your brain suppose to learn from this - but after playing video games people just got exhausted... Example of that kind of games were known for a long time - take card games for instance. Don't you mean that card games "claim artificial intelligence?".

    You forgot radiation term that goes as 4-th power of frequency += G*f^4, G- is the defined by the geometry factors... You hit this limit as you go to ~GHz clock speed.
