Deja vu here; I used Wolfram Alpha to study calculus and I had a final exam on it this morning.

In terms of a study tool, it was invaluable. I always try to do a question by myself first, but instead of writing MATLAB/python to sum a series to infinity, I can check my answer quickly in Wolfram. Same goes for limits, sequences, integrals, differential equations, etc. Knowing that lim n-> inf. ((n+1)/n)^n = e is not much use unless you actually understand what is going on; that is where the marks come from.

Oh and we were not allowed to use calculators (this is the top university in the state).

According to wackypedia, FTTP is usually FTTH (not FTTN). Also, from what I have read on the various news articles about this, the network will be regulated to hell and back so the company that owns it will not provide retail services on the network, just wholesale. Seems like a pretty good idea to me ?

Another vote for Mozy. If you want to try it out, up to 2GB is free.
