yes but it's no where near as fast as an x86. a calculator uses differnent ways to store numbers so that it's more precise, but it's god awful slow compared to a computer.

this is a very common issue when working with floating points. you should never check to see if two floating points are equal, unless you mean equal to all precicion. a much quicker way than using sprintf is this:
#define EPSILON 1e-6//or what ever tolerance you want
float x,y //do stuff with x and y
if (fabs(x-y)<EPSILON) { //x and y are equal } else { //x and y are unequal }
actually, the real statement is not "nothing can go faster than the speed of light" but "information cannot be transmitted faster than the speed of light" it is possible for light to travel faster than the speed of light in a plasma, however any information encoded in the light wave will travel slower. there are two types of speed when talking about light...there is the phase velocity, which is what we think of as the speed of light. but there is also the group velocity, which is the speed a pulse travels. if you think, a standard sine wave carries no information, if you want to send information you have to combine many different frequencies to create a pulse (think of the fourier transform of a pulse). so now you send this singal through a plasma. each frequency will go a slightly different (faster than the speed of light) speed, but now those frequencies are a little out of phase with each other, and the original pulse is going slower than all of the components.
This morning we got the "PVR users are thieves" message from Turner's CEO. And now we see AOL making it easier to use TIVO? Turner is owned by AOL-Time Warner. Doesn't this seem strange that they say it's bad but make it easy to use?
most of the comments on this discussion have delt with em interference of some kind. i bet that this is indeed the case, if you can't get rid of the interference, you can block it quite easily. one thing we do with sensitive scientific equipment is to put it in a faraday cage. this is just simply a metal wire cage. em interference cannot penetrate a conductor (as long at the spacing between the wires is smaller than the wavelength of the interference - the interference you're getting is probably on the order of 1 meter or longer, so you have nothing to worry about). you should be able to get away with a cage the covers the back and sides of the monitor - it would be kinda useless to cover the front:). if you know where the interference is coming from (i.e.wires in the wall), you can just block the source (put a mesh between the wall and your monitor). hope this helps.
no. tucking is all about wind resistance...you cannot change your momentum by changing your mass distribution...you can only change your momentum by the application of an external force.
the reason ice skaters pull their arms in, is to increase their rotational velocity, not their rotational momentum. the angular (rotational) momentum is constant (except for the loss of momentum due to the friction of the ice). since angular momentum is the product of the moment of inertia and the angular velocity, moving your arms in decreases your moment of inertia by placing more mass near to the axis of rotation. to make up for the decreasing moment of inertia, the angular velocity must increase to keep the momentum constant. conservation of momentum is once of the holy grails of physics.
here's how i did it when i switched over to linux from windows. i used mozilla for windows to convert my outlook mail into mozilla format. mozilla can do this because it uses a windows dll to read the outlook format. then all you have to do is copy the mozilla mail over to you linux box and you can read it using mozilla mail (which is what i do), or most of the other linux mail clients will let you convert from mozilla format to their own format.

actually my favorite problem is "my microsoft wont work". i've gotten that one more than once.
