Week 1

The first week of class was just very confusing for me because I've never learnt computer science before but it was still very interesting.  I think the basic idea for commanding computers is to use understandable and logical steps to solve problems   using computers instead of human brains. The new things that I learnt were algorithms , some basic codes for commanding, such as: flip- vertical, etc. 

Since I still feel unfamiliar and confused by some stuff in this course, I haven't find any thing that I enjoy doing. The most frustrated thing is to use the program DrRacket. I don't know how to define some of the commands. For example. I wrote "flip- vertical", and followed the steps in the videos but it always told me that the function "flip-vertical" is not defined. I think I need to ask for help for this. 

The codes are not hard for me to understand. They are really straightforward so I feel confident about them. One of my achievement this week is that I set up my CDF account and I downloaded the DrRacket for my OX system. 

I believe that in the following weeks I would get more involved in this course.
