Let Google Calculator Get the Modulus for You!

In a math class this fall, the teacher has some difficulty calculating the modulus of a large exponential. I didn’t have my trusty Texas Instruments calculator with me at that time but tried to calculate the answer using Google on my Nokia phone. I was quite surprised to find the answer by just entering the problem directly into the search field of Google:
or, 8 to the power of 6 modulus 11, which is congruent with 3 (if you needed to know that). This is very useful for calculating the modulus required for encryption problems such as RSA public key and Diffie-Hellman key exchange math problems and times when you don’t have MatLab, Excel or Mathematica at hand. (Or if you only have Opera Mini preloaded on your phone…)
Is Anyone Selling High Resolution Music Videos Yet?

It just hit me while watching a music video on YouTube that: is anyone selling high resolution music videos on the net yet? Sure, iTunes is selling some music videos (and that’s a US only feature?) but as far as I know those are not really HDTV quality like in 720p resolution.
Anyone notice some legal source of HDTV quality music videos that you can buy anywhere? If not, this might be a great business area for the BitTorrent company to move into once they’ve gotten the old farts in RIAA convinced of the business prospects…
