    AI optimal rotation of a rigid body

    Actually you've taught me why we do it with 3x4 matrices... hadn't realized angles weren't independent. Is there any reason you are not using matrices?

    Java Retrieve Browser state information(Java)

    OK friend says he doesn't know any *simple* way of doing it. With a static page you can do some dirty code to check it, but it's not reliable. He recommends you time out the download after a set interval, then parse the contents of the page to determine if you think it's complete. I am sorry I...

    Java Retrieve Browser state information(Java)

    This does far more than you need, it's basically ajax for java http://directwebremoting.org/dwr/index.html edit: I am sorry, please ignore this. I'm tired and I'll edit it later. I don't think that;s what you need. Basically I misread the question and didnt't realize that it wasn't your *own*...

    AI optimal rotation of a rigid body

    I think understand the question now. Your ship facing is (0,0,0) degrees and you need to turn to (60, 40, -90) degrees (e.g. 60 yaw, 40 pitch, -90 roll), and you want to model this turning by "Newtonian" rockets that obey F=ma, so the ship's facing will start small, increase constantly, then...

    Java Retrieve Browser state information(Java)

    Change the body of the function to be your code, not the popup. BTW `window.onload` is javascript.

    Acoustics: Directing Sound Waves

    I have heard the term "phased array" regarding non-steerable emitters for radars. I wasn't aware of other uses - thanks!

    Suggestion Can we cool off on the warnings?

    Found this one - "sends friendly message to user, when user's thread is moved" http://www.vbulletin.org/forum/showthread.php?t=225619 That's for 3.8, which is what this site says it is running (view page soruce for this page says 3.8.7) There's literally *thousands* of plugins for vbulletin...

    Acoustics: Directing Sound Waves

    does it have to be a parabolic emitter? Military sonar does not use a large parabolic emitter. I don't understand what it is, but they have a large number of smaller emitters that I believe can emit in various controlled directions without mechanical moving parts (perhaps electrical...

    How can I automate opening email attachments and entering data into a form?

    If the data is in exactly the same format every time you can use a keyboard/mouse macro recording program like "AutoIt". However, this will fail if it cannot work by playing back pre-recorded mouse movements and clicks. (i.e. window in wrong place = miss = fail). EDIT: However if you know the...

    Randomization Question - Get a Clear & Informative Response

    K&R (the original C programmers' textbook that started me down this dark path) provides this as the source code for rand () unsigned long int next = 1; int rand(void) { next = next * 1103515245 + 12345; return (unsigned int)(next/65536) % 32768; } It requires initialisation of the...

    Quantum Computers: what are they better at?

    Can someone explain to me what sort of things quantum computers can/could do, based on their differences in their design, that are harder for conventional computers? So far I have a list that consists of 1) integer factorisation. I was hoping someone could extend that for me! :-) After all...

    Suggestion Can we cool off on the warnings?

    vbulletin doesn't have a module for it? I find that very surprising. Edit: it does have plugins for it. Is this a restriction from the hosting provider?

    Do Ads Still Pay Well? Investigating Online Advertising's Viability

    Sorry, I think I misread, did you actually say Facebook have trouble monetarising? I am shocked to hear this. Reddit, I don't know, but they're a huge website. Digg had an outdated business model, I suspected they were headed for the clapper. They tried to create a controlled social...

    C/C++ Why Does g++ Require -fpermissive for Default Arguments in Some Cases?

    I don't know how people remember all the words like declarations and definitions; I was never that strong on it, and using dynamic-typed languages has blurred the line for me.

    Understanding the Psychology of Pseudo-Scientists: What Drives Their Delusions?

    Which is itself a faith ... Unless you can say you know absolutely, for certain, you can prove you aren't living in a simulator? What about string theory? So the people working on string theory, without the ability to verify it experimentally? what are they working on drives them if it's not...
