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...

InnovFest 2015

I attended the innovFest 2015 event. It was quite eye opening. Besides the booth, some topics in the forums also interested me. The first topic I joined was the Kopi Chat with Yossi Vardi, a famous Israeli entrepreneur and investor. He is straightforward and humorous. When talking about the most important reason why people wake up with a great idea but ended up sleeping without executing anything, he collected answers from the audiences. One answer pretty much fitted his appetite-- "People fear about losing faces". He shared his opinion with the quotes from Theodore Roosevelt, “It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually st

Consistency Matters

I didn't post anything last week, which means consistency has been broken. There's a need to reflect the task management skills, otherwise I'm very likely to driving the wrong road Priority changes. A good exercise would be to list the priorities down everyday and assign reasonable time to the tasks. Then never second-doubt. 100% focusing on the task when doing it. Priority changes from time to time.  Human minds are single-threaded, thus, we'll need to keep focused when doing one particular task. Be Grateful. I received the confirmation from NOC Israel that I got admitted by the programme and I'm heading to Israel next Jan:-) Thanks a lot for Prof.Ben and Karl's help. Ultimately, it might be a plan from God. Thanks every one. The additional interview from Google went well, however, I didn't get the winter intern opportunity this time. Though it's a bit too greedy to ask for too much, I still feel a bit sad after informed that I didn't get th

Thoughts

I've been working as a project manager on an interesting project named " Dadafish " for quite some time. The intention is to create a sharing economy platform for lifestyle teaching/learning. Put in a more straightforward way, an Airbnb for classes. There is one assumption:  People are willing to pay to learn skills from amateur or semi-pros at a lower price. Quite some ongoing arts classes in meetups are taught in cafe shops at 15-50SGD/session. It's an indirect validation of our assumption. There are also many free language classes in meetups and facebook groups. We did an experiment to validate the assumption by introducing a Japanese friend who's organizing a free meetup to teach Japanese. She doesn't have a certificate and she's currently teaching Japanese in meetups for free. The experiment class was charged at 15 SGD/h per person for a 3-4 pax group class. We posted the class and teacher info in a NUS student/alumni SNS group and three peopl
