This week we looked at the different types of communication and privacy of data. We looked at how some things can get you in trouble if they are made public. Some of this really surprised me. Now I recognize that I have to be more cautious in the future.

We also watched some technology related videos. My favorite was Johnny Lee's presentation on the wii remote and its infrared light sensing. I had never thought about this technology that way, so seeing all the seemingly magical things that resulted from it was really interesting.
