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
http://www.gamedev.net/page/resources/_/technical/game-programming/2d-rotated-rectangle-collision-r2604
2)Basic matrix rotation
[x,y][cos  -sin]
        sin   cos
3) Determine if two rectangles overlap
http://stackoverflow.com/questions/306316/determine-if-two-rectangles-overlap-each-other

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...

Time to Write sth about the NOC Israel

After more than a month's waiting, I received an email today from the Financial Aid office saying that I am not permitted to go for the NOC Israel programme. 

Dear ShaohuanI refer to your appeal to participate in NUS Overseas College (NOC) Israel.As spoken on 6 November 2012, we understand that you are very eager to attend the NOC and we had submitted your appeal, together with the appeal from NOC to the sponsor.  However, we regret to inform you that your appeal to participate in NOC Israel is not successful.   The sponsor has advised that you look for an internship locally instead, if needed.We wish you all the best. 

Actually, I was informed by the NOC coordinator that she has been informed by her colleagues that the sponsor officially rejected my appeal(together with Prof.Ben's and NOC's appeals) on 21st Nov. She tried to confirm with her colleagues whether the decision is final or not, hoping to help me for the last try. However, I guess the result won't be positive…

Learning Public Speaking

In the past few weeks, I've been exploring the methodologies of public speaking that work for me. It takes a lot of trials and errors until I finally see some progresses. It would be good to share my thoughts and experiences so that people see my posts can have a more confident and effective start for public speaking.

Firstly of all, you need to overcome the fears to public speaking.  The common excuse I take is that I'm an introvert person. You have to be an extrovert person to master public speaking. However, that's not true. Public speaking is a skill, it can be trained and mastered. It may take some natural talents to be a super-influential speaker. But for a normal person to hit a point to deliver your messages clearly and powerfully, it's doable.

One of the inspiring talks I heard from an introvert speaker is Susan Cain's "The Power of Introverts". Susan says that introverts sometimes can deliver deeper thoughts than the extroverts.

On "Kitchen Nightmares"

This weekend, I watched a few cuts of TV programmes on Youtube.

Listed as below:
Gordon Ramsay's Kitchen NightmaresGordon Ramsay's on Bad Boy's BakeryGordon Ramsay's escape to Thailand They are indeed quite inspiring. I didn't know these programmes until I saw someone shared the initial cut on the "5 dishes that Gordon Ramsay actually liked" on Facebook.
The immediate question came into my mind: "Why he's so pissed off with someone else's kitchens?"
Then I started to watch the other clips which tell the whole story. After watching a few clips, I started to realise his positive intention of helping those restaurant owners who are suffering in their F&B businesses find right ways to recover. The story normally starts with a failure restaurant. Then Gordon will taste their food, followed by investigating their operations. After identifying all the key issues, Gordon will give advises and transform the restaurant into a more promising one…
