No love for the EE

I would probably start around question 100 as below that would be pretty easy. I did some Matlab back in school. I'd be interested to try Octave, the open source alternative, and see how capable it is. Using Matlab to solve these problems could be considered cheating, since if you have all the library packs, a lot of the low level problems have been solved already, it's just a matter of finding the right function. Writing solutions from scratch in C using nothing but stdlib would be much more educational, programming wise.
Not that they're around any more, but Exar and Eyen would also be good at these things.
