Weekly Memo

The biggest thing for this week is CS3217 Assignment 1!

I fixed one last bug right around the deadline, which is fortunate.I feel like dying in the first assignment, but it only worths 5%! More tasks are expected to come later. It's not possible to be lucky all the time, thus I'll have to start the assignments earlier next time.

During this week, I did learnt quite a lot of software engineering stuffs.

1. Algorithms
1) 2D rectangle rotation collision using the Separating Axis Theorem

2)Basic matrix rotation
[x,y][cos  -sin]
        sin   cos
3) Determine if two rectangles overlap

2.Objective C
It's not so hard to understand as a programming language. However, I still got some problems understanding some basic terms like"Protocol(which is like interface in Java)","Delegate Class" etc. Will need more time/ask more to get to know all these.

3.How to Code
1)Do the research on how things can be implemented using a good algorithm before coding.
2)Test cases are important to validate the codes.
3)Good coding styles/clean code is important.
4)Spend more time&effort!
5)Ask peers when something is unclear to me before the last day.
Above all, the 4th principle is the most important. I didn't do well this week. Hopefully will do better and better.


That's it. Anything else seems to be non-important this week...
