Recently I realized that I am an adult! Yes, there are only 2 years to my mother's retiring and there are only few years to my working. I am 20 years old now, I am a youth! I should shoulder ability from now on.
From now on I will be a youth, a new youth. From now on I should think something different and my times is coming! I should not only sleep and play games all the day without thinking anything.
Though I have done something but I still have a lot of things to do!
So from now on there will be a tag that record other youths' which are standing and my own thought!
In my opinion a excellent youth should be a man who is self-confident, optimistic, diligent and having his own thought.

Software Engineering--Is there a useful model
In today's lecture--Software Engineering,we talk about the models in Software Engineering which can discribe the developing progress. We talk about models from the formal Waterfall Model to the lattest Fountain model. My teacher Haiyan Che(in Chinese 车海燕) said that software developing is an iteration progress, and the OO(object-oriented) is the most useful way now, so the Fountain model seems the best.
But in my opinion, those models still have a unity. In my formal two years I have used most of the thoughts of these models to develop, But to manage a item is still a very very difficult thing.
Sometimes I even cann't stand the enormous pressure! I think managing a item is a thing which need courage. You should always shoulder huge pressure. Sometimes I even think I cann't stand any more!
As to my formal experience of failure you can see my javaeye(http://bbsunchen.javaeye.com) blog which is written in Chinese. I create this blog is in the hope of ask for people's help. But it seems that there are few people who have enough experience. I think I am lack of enough good experience.
In my college, students will form a 4-6 members' team. In these teams, all the students are lack of experience, so they will have to go through a hard period. Fortunately, the team which I am in do well in this period and we create many excellent software.
To come back to the subject, I am thirst for a really useful model which can guide the developing and a really useful method which can decrease the pressure that the developers have, especially the managers have!
To this subject, I create the tag "Software Engineering" for sustained attention.
Welcome to share your opinion!

How to to take precaution against computer game
Recently I want to get rid of the computer game. I do not mean that game is a bad thing, but you know I am a man who will forget any thing when playing games. Once I start to play games, I will be addiction to them and can not stop.
I think that is because when I start to play game I will feel guilty for not studying but playing. But I think there are other reasons that make me addict to it.
I do not know how to control myself so I just prevent me from playing them.
But you know it is a hard thing! There are a lot of people playing games every day around me! I just can not stand this situation!
What I do now is to convince myself to get up from the computer and have some exercise and do some games without computer such as playing card and so on. But you just cann't find a person to play with you because your friends are playing computer games!
Can any one help me?!

How to learn computer science
From now on, there will be an tag in my blog called "Teacher forum". In these articles there will be important opinions from which I learn in my usual classes.
This time I want to talk about how to learn computer science(CS) and Algorithms. Computer science is often said to be the hardest thing to learn in the world because you should learn many math and you should always think about a lot of things when you solve these things.
Here I don't want to talk about what I think about this questions. As I said before, I just introduce my teachers' opinions. In today's classes, my teacher of Data Mining and Artificial Intelligence(数据挖掘和人工智能) whose name is JiWen Guan(in Chinese 管纪文)said "If you want to learn things, you should master the basic definition and understand them. Only in this way can you learn them. This is also right to Computer Science. After mastering them, there will be Aura in your brain when you solve problems." Guan is the most famous teacher in China in the area of Computer Science and I respect him very much. He is in his 70th but can have class for about 2 hours with high spirit.
Another thing I want to refer in this article is my Algorithms class. My teacher is XiaoDong Zhu(in Chinese 朱晓冬), he is a young teache in Jilin Univisity. When he is talking, you will forget the time.
Today he talk about a question. There is eight players and one is definitly better than another. That is to say when any two of them have a match there will be a winner and a loser, in the same time ,no matter when and where they have a match, the winner will always be the winner and the loser will be always be the loser.Then how many matches do they have to have to find the champion.The answer is 8.
Then how many to find the champion and the second place?
You can solve this problem like this:
In this picture, there are 8 matches to find the champion, and the rest thing is to find the second. You will find that the second is the one that have had match with the champion, or he will not lose. So you just have to select the there players and let them have 2 matches. So the answer is 10!

My new home-Hello World
Hi everyone, my name is bbsunchen. Sunchen is my Chinese name and bb is in the name of my home town BengBu.
From now on, I will use this blog. At the beginning, I used the Baidu blog http:hi.baidu.com/bbsunchen.
I do not mean that google is better than baidu, just because I use the gmail, so I think it may be more convenient to use this bloger. Even more, I think that hi-baidu have more functions than google-blogger.So when I public a new article, I will update the hi-baidu blog.
Another reason I create this blog is to make my blog more international, that is to say I want much more people to see my article, to see my thought, so we can conmunicate with each other.
In this blog, you will see articles about life styles, computer science, math, art and economy. There will be no words about policy and so on just because this is only a place to make academic exchanges. So please value my opinion and value this place.
As English is the most popular language in the world, the author will respect most people's habits even though I am a Chinese and even though my English is not so good.
Welcome to exchange your thought and welcome to correct me.
