I post here because of the importance of my message:
DO NOT break security to prove its inefffectiveness. it is ILLEGAL and you will get into major trouble for it.
Find ways to speak with the local sysadmin, show them how vulnerable they are-- most responsible ones will listen no matter who comes and tries to speak with them.
But remember this: when dealing with somebody who might consider themselves an "adult" compared to you, approach with an air of maturity and try to reason with them, if anything, for the sole purpose of responsibility. If you believe in your ideals, don't give up, but NEVER resort to irresponsible behavior-- you will be doing more harm than good for both you and your classmates.
It might also be that red is the color of our blood-- it might be evolutionarily optimal to respond most strongly to the a color that is guaranteed to be emitted when we are badly injured.
I've had to replace two major parts on my pismo in the last year:
1. the hinges on the LCD 2. the sound IO-power board
both of these two operations could have set me back at least $1000 USD combined if I sent the machine into apple for repairs.
I went looking on ebay and around the net and fixed my laptop for $200 (in the form of parts and torx wrenches) for both repairs combined. Even then I paid too much--but those manuals are still a godsend.

there are some great papers on this site that might be of interest
you mentioned information theory-- that sparks a thought: don't data compression algorithms level out some of the statistical irregularities in a message? maybe that might help in making it harder to crack. (transmitting the code table obviously introduces some security problems, but lets forget that for a second:-) )
hey, just co clarify: 64 bit can mean more than just the address limit. from what I understand, typically it refers to the word size in the chip, i.e. number of bits usually associated with an integer datatype. it usually just so happens that memory is addressed with integer-sized numbers. I used to think that it referred to general-purpose register size, but now with all those SIMD instructions being added to modern processors nowadays, the labeling gets a little screwey.
64 bit chips tend to be faster than 32 bit chips when it comes to crunching large amounts of data even though the logic might be more complicated because if the chip is designed right, cycle for cycle, it can usually process twice the amount of data.
I find it interesting how much of hollywood tries to portray dinosaurs as savage beasts. how many future civilizations would call us humane, with the we way kill each other so easily?
break up the iimage into N x N submatrices, and do a fourier transform on each subsection of the image. then do this for the next frame, and calculate the phase differences between each frame, and use linear/cubic/etc interpolation to generate the frames in between. not too difficult, and I think there is even a 2-D FFT library located somwhere on download.com. this, however might introduce a couple of artifacts, but if you're doing high framerate video, it shouldn't be too noticeable.
or even more far-fetched:
assuming that the translation of the objects in the image plane between frames are small and uniform enough, you might also be able to pull this off with a properly trained neural network on subsections of the image (so each individual feature fits approximately in each subsection). neural networks can do non-linear regression, but thier outputs are continuous, so I figure if you train it right, it'll give you what you want.

This has nothing to do with the above posting.

illuminate me. thanks.

why don't you try this far-fetched possibility:
:-)
break up the iimage into N x N submatrices, and do a fourier transform on each subsection of the image. then do this for the next frame, and calculate the phase differences between each frame, and use linear/cubic/etc interpolation to generate the frames in between. not too difficult, and I think there is even a 2-D FFT library located somwhere on download.com. this, however might introduce a couple of artifacts, but if you're doing high framerate video, it shouldn't be too noticeable.
