HW 2-3

Thoughts and feelings on HW 2-3
--------------------------------
I believe HW 2 as a whole has been a good introduction to Rails. The third part of this homework meant remembering the sorting and Ratings-filter settings between client requests. I first solved this without using redirect_to for missing params (where the corresponding session-variables existed). Since this solution is not RESTful, I rewrote the code to make use of the redirect_to to preserve the settings as params in the URI path.

Regarding pair-programming:
It's always good to have an extra set of eyes looking at the code, especially as it is being written (by the driver), and I believe pair programming may have led to a different final solution. Since there was no explicit coding standard pointed out for these tasks, there's a small risk that the driver/observer, in a pair-programming scenario, would get stuck at arguments over for example naming conventions (abbreviations vs. no abbreviations, etc).
