2.9-2.11, due September 20

1. Difficult: The most difficult thing for me in the reading was understanding the linear feedback shift register. There were just so many congruences and I didn't know where different things were coming from.

2. Reflection: The section on pseudo-random bit generation had me thinking about how many times I used the function rand() in my computer science class. I didn't realize that it was really that predictable. The text said that it was and I was like wait a minute I thought it was actually a random number.
