My last attempt on System analysis was a failure.I won't miss out this opportunity again, I will try my best. It is a new start for me.
Basically I have done all sections on CodeAcadmy the last time I took this course. But to review and learn from failure,I design I will do them again. I am also hoping that I can find some basic or intermediate Ruby learning website like CodeAcadmy. I have seen Professor Joseph had included several other ways for us to learn more about Ruby, which is on the BerkelyX Lecture section. Like there is tryruby.org. This website is similar to CodeAcadmy but less lectures. The good thing about this website is that it lists shortcuts and commands which allow us to go through the sections simply control on the keyboad. But there is also a thing I don't like which is every commands and sections are on the same page. It is very hard to find out which one is it when you have reached the last objective.You have to scroll down and up look up which command you have used for the string fro example or which is for which formula. In this case, I think CodeAcadmy is more clearly.
I haven't explored the other two websites yet, but I will. I am also
happy to hear from some of you if you have found some very good sites
about Ruby.I hope you can share with me. thanks
