4月8日 How Good Is Uvic?AWRU, The Academic Ranking of World Universities, is considered as one of the most credible ranking of higher learning, having been cided by the journal Economist. The methodology takes many aspects into account, which is believed to be unbiased. Other rankings have similar results. Since AWRU is one of the most famous ones, we use it as our reference. In AWRU, Uvic is ranked 203-304 in the world, 99-138 in North America and 8-17 in Canada. Seems fair to me. However, I still cannot tell how good Uvic is from the ranking, because I don't have any instinctive sense about the relative ranking in the world. Well, I know Chinese universities a lot. So why don't I just compare Uvic to them? There are 14 Mainland Chinese universites on the list out of top 500 in the world: 1 of them has higher ranking than Uvic, 151-202 in the world. It's Tsinghua University. 5 of them have the same ranking as Uvic, 203-304 in the world. They are Nanjing University, Peking University, Shanghai Jiao Tong University, University of Science & Technology of China, Zhejiang University. Other 8 have lower ranking. They are Fudan University, Jilin University, China Agriculture University, Lanzhou University, Nankai University, Shandong University, Tianjin University and Zhongshan University. Still seems fair to me. Notice that the effect of size is already under consideration, so large population of students and staff doesn't benifits in AWRU. Furthermore, if you ask, I want to say that Chinese universities are underestimated. By looking into the criterian, we can see that the accomplishment of alumnus weights much. For Chinese universities are newly rising power, they don't have gorgeous past but splendid future. In this sense, European universties are falling. I don't think Uvic is as good as the Chinese universities with the same ranking, say Peking University. One of my friend, Jason, is going to have courses in Peking Universty, due to some exchange project. He said he is a bit afraid, because he heard that students there are really smart. Yes, compared to those in Uvic, they really are. Sometimes the rumor is true. It makes perfect sense. Suppose all races are equally intelligent. Assume Uvic is of top 13 universities in Canada, and Peking U is the top 5 out of 500 universities in China. Canada has population of 30 million? Maybe Uvic gets the top 20% students. On the other hand, China has 1.3 billion population. Peking U takes 1% the most qualified kids in China. Top 1% in 1.3 billion, which means geniuses. This goes to a long controversial question that the factor makes people great is innate or postnatal. Frankly, I suggest both, 50 to 50. Uvic, comparing to my previous university in China, does have better management and courses. That helps for some extent but not for all. Speaking for the truth, some people are more talented than others in this world. If you are as tall as Yao Ming, you can be a good basketball player. It's not that obvious in intelligence, but it does exist. I'm tutoring students in Uvic. Sometimes I think, gosh, if these kids were in China, they would never make it to a university like Peking U. If you believe that people are born differently intelligent, then it's no denying that Chinese universities have the best. And now the rising China has the economy can back them up. More and more scientists select to go back China not only because patriotism, but also profit. In the years to come, Chinese universities will be going up dramatically. 4月4日 Study, Research, The Beginning Of The EndThe last exam is over. There is one whole month before the next semester. I didn't know I would have such a long break. I should take the advantage for homecoming. Well. First, I didn't plan for this trip, so I don't wanna hustle. Second, other things are coming, so China can wait. Anyway, I didn't expect I can actually rest during "break". My response is more like the 3rd year student below. It's only one course left now, and it doesn't matter. "Take the easiest course," My professor said. "now you should focus on your research." He gave me a bunch of fancy gadgets as well as tasks during break. They are programmable sensors I should work on. I think it's cool. I'm looking forward. And It's something practical that helps in career. I'm tired doing research only on my labtop. The world is bigger than that. My former research, the shortest path problem assigned by my supervisor, was too theoretical that nobody would never pay me to do. We have theory group in our department. They do math. So why don't we just leave those Big O Notations and Inequalities to them? When I first came to this grad school, I wanted to do something with AI. Now I don't take it serious anymore. Survey shows that AI is the field that most scientists want to work on. AI is cool but it doesn't pay that much in career. We can draw this conclusion from I couldn't get any fund when I applied to study AI as a grad student, so I had to change it to my current supervisor. Let's be realistic. I don't even register the course "Artificial Intelligence" this summer. 3月30日 One Slide Of My Coming PresentationThis is from one of my a presentation of a course project. I don't even bother to add a background to the slide. About the figure, I drew it in MS Paint within 3 minutes. As illustrated in the phd comics: I'm not lazy. I'm an effort minimalist. Course is just the least important thing to a grad student once you are not planning for another degree anymore. In that case, you need good grade for fellowship. At least it's easier to get A here than that in my Chinese grad school. 3月18日 Graduates Like Marriage1. In Engineering, only 12.3% are female. You don't say. 2. In Earning, male PhD $82,619 outperforms MSc $64,533 I don't understand, because I don't think education makes people better. Educated people are more qualified because you need to be qualified to get education, like you've to be richer and smarter to go to better university. So, conversely, the rich family and intelligence are the real reason supports you in future career market, not the courses taken in university. Schools teach nothing. Whatever, I'm still hang in there with my MSc. $64,533 times the exchange rate, that is... much better than what I can get in China. Although it must be much lesser in Canada. 3. In Marriage, Grads 24.7% single rate outperforms 28.7% general population. Yeah, that's what I'm talking about, more likely to have normal family. But I suppose those extra 4% people are too bored so that they get married in grad school. 3月12日 Am I Tired?Today, a German guy told me I looked tired. Did I? I feel OK though. But, it's hard to say. Maybe I'm just too anxious to feel tired. If so, that's not a good news. Pressure makes you running faster, but also burns you out. And I don't wanna be burned out. Diligence is harmful when frantic, is not when organized. I should be like Winston Churchill said: "In difficult moments, behave like a duck. Keep calm and unruffled on the surface, but keep paddling away underneath." Anyway, I do need a mirror in my office. 1月16日 IllusionPeople are slaves of sentiment. Seeing is not necessarily believing. Sometimes you think you can see the truth, however, they are just illusions. Only the preciseness of rationalism unveils the hidden rule of the world.
I used to think that the number of Canadian in Computer Science department is limited. Recently, I find out that there are still many of them.
I drew my conclusion by observing in the senimar course. Unlike other courses, senimar course is the the only one that is mandatory to all grad students. Other courses could be biased. For instance, math courses have more Chinese. Senimar course is the only unbiased data source I can get.
In the course, there are 18 students of all. Among them, there are: 7 Chinese, 2 Indian, 2 German and 1 Iranian.
That's 12 of all. Rest of them are either native speakers or European I cannot distinguish. Let's suppose they are all native speakers. One of them whose accent is too strong as well as he is too arrogant to be a Canadian. I guess this guy is from USA. So there are 5 left.
There could be up to 5 Canadian, which is almost as many as Chinese. That's a lot. I didn't see this coming. 1月10日 TeachingFate is ironic.
I teach the same lab this term, as well as another one.
1 session for CSC100 Lab
2 sessions for SENG130 Lab
Until now, I haven't got in touch with the professor of SENG130. I know this guy. He is not actually that kind of responsible person.
I tought a CSC100 Lab this morning. Teaching is exhausting. You have to shout to them for 50 minutes during each session. I think my teaching skill is better. Last term, I considered myself as the worst teacher in the world history. I can only speak for 20 minutes for each session. Thank god it was a lab, otherwise it would be really awkard. However, this term, I can teach wall to wall in 50 minutes fluently with proper timing.
I have learnt from my previous failure that confidence and determination is really important in public speaking. Just pretend to be a good speaker, and make your students to believe so. They will act back.
Instructor is not a good job. The light side is, it is helpful to my speaking English nonetheless. If everything goes well, I will try to teach senior courses in the future. 1月3日 When Canadian Meets Each OtherI went to orientation today, a orientation for new students. During the orientation, two people found out they are both Canadian.
"You're Canadian. I knew it!"
"I'm the only one in the lab!"
"Me too!"
They were excited. If they were Communists, they would call each other "comrade" by then. The scene was heart-warming and convivial. I loved it. I'm sorry I didn't bring my camera, but I have a analogy here. It's pretty much like this one below:
April 25th, 1945, during World War Two, US and Soviet forces linked up on the Elbe River, a meeting that dramatized the collapse of Nazi Germany's defenses.[1]
Compared with that, it's not really exciting for me to meet my ubiquitous countrymen.
1月2日 My GradeGrade means nothing. There is a article on my supervisor's homepage, "How to ruin your graduate life." One thing it says is "always try to get good grade." In the author's opinion, he believes that a grade of B on average is enough. He suggests students focus on research not courses.
Theoretically, I agree. I hate courses too. However, practically, I must work on it as much as I can. Due to the policy, to us, A- is the passing line. If you fail, your money is gone. Pack your stuff and go home. That's why I am so nervous about this. It's the sword of Damocles hanging on my head.
I had 2 courses last term, and I just got the grade today. Lucky me, they are all passed.
CSC 482b/523 Randomized Algorithm
Grade: A-
It is said to be one of the most difficult courses on campus, purely math. I worked really hard on it, and I believed I should get a A. The reason of I didn't get one is that I made a rookie's mistake. I was too lazy to write my proving in detail. Time to time, I just proved the lemma in my head and write down: "It is obviously that ...". One day, the professor changed her marker, and the new marker is very strict about this. So I fail the following assignment because of imprecision. Otherwise, I can get >5 more points in my final grade.
Actually, I have more complaint about this... but anyway, since A- could be also considered as acceptable, so why don't I just save my bitter words as well as troubles. After all, it is a valuable lesson. Math should be prudent. My proving is indeed a problem. Sometimes when I read my writing, I don't even understand myself.
Learning from mistakes, that is the true meaning of taking courses, isn't it?
CSC 450/550 Computer Networking
Grade: A+
Comparing to the first one, this course is much easier. Basically, in Computer Science, the difficulty of a course depends on how much mathematics and programming it has. Good news, this course has barely no math. You just need to memorize those protocols and jargons.
As for programming, frankly speaking, it scared me at the first time. It requires programming in C/Unix/Socket/Pthread, which I've never used them before except a little experience on C language when I was a freshman. (That is, 6 years ago.) I thought I would be dead.
Actually, I shouldn't worry about it. Once I got to know it, it became easy in no time. So after a few weeks, although Canadian kids were still complaining "the lab is too hard", it didn't bother me anymore.
To sum up, it is A on average, not too good, not too bad. One have to take 6 courses to get a master degree. So for me, that's 2 down, 4 to go. I'm coming! 12月4日 Being A White MouseI took a part in a psychological experiment today. I don't know why I did this. It's the end of the term, time is limited and everything goes crazy. Well, it's me. I always do things don't make any sense. Sometimes weird thoughts just come off the top of my head, then I say: OK, why don't I just ... (some stupid ideas).
For this time, I think it's because I am always curious about the psychological studies in Scientific American. Plus, I can get 10$ easy money for 1 hour work.
The psychology lab is in a basement. When I came, another volunteer was already there. We exchanged some words:
"What's your major?"
"Computer science"
"I'm general science." (....What's general science?)
"Are you a resident?"
"No, I've been here only 3 month. And you?"
"I live here for 20 years."
...
blah, blah, blah.
It turns out that they are taking some classes, so they do the experiment for bonus marks. I wish I could do experiments for marks. Let me think, what kind of computer science experiments need volunteers ....
Before I got an answer, a researcher came to us. "Pick a number from 1 to 10." She said.
Another guy said: "7."
I said: "Is it a part of the experiment?"
The researcher and the volunteer: -_-|||.
Then I found out this's like a coin flipping. For example, the researcher keeps a number in her mind first, and whose number we tell her is closer to hers, wins. Then she can assign us to different groups in the experiment.
After this, the experiment began and it lasted for one hour. It's a role playing, quite fun. I'm sorry I can not reveal more details since it's secured. Anyway, it's an interesting experience and very neat ten dollars. 11月24日 The Difficult CourseRandomized Algorithm, instructed by Valerie King, is considered as one of the most difficult courses in Uvic. Students keep dropping this course. They might cannot follow or they just simply think it doesn't worth it. In the latest course, we need to deliver our homework, so I assert all the students who suppose to attend were there.
Guess what?
There are one Bangladeshi, one Canadian cool guy and four Iranian. Besides, rest of the students are all Chinese.
Yeah, sometimes it does feel like home. 11月23日 Poison TrialI talked to a professor about math. I tried to say something about "Poisson Trials", but what I really said is "Poison Trials". (click here to listen to the real pronunciation) The professor is a New Yorker, and she was totally shocked:
"What?!"
After understood what I meant, she laughed out loudly. "Poison Trial... It's like a trial you never want to take." She said:" Well... Poisson... Poison, they look similar though." 11月5日 One Hour Beyond My LifeYesterday afternoon, it was Sunday. When I was working in the lab, I glimpsed my watch. It was 6 o'clock. I thought it's the time to have meal, so I went back to my office to eat.
Suddenly, I found something weird: It's only 5 o'clock in my laptop! I checked my watch again, and still, it's 6 o'clock. "Which one is right?" I got confused. That's the problem of having 2 clocks. When you have 1 clock, you always know the correct time; when you have 2 clocks, you got confused.
I thought: "Am I crazy already?" For a second, I thought I was crazy. I was even disappointed by myself. I used to consider myself as a tough guy. But now, only working 80 hours per week, this tiny little thing can drive me crazy? It can't be true.
Thank god, I have the third clock to help me out, my cellphone. My cellphone told me that the time is 5 o'clock too, the same as my laptop. Apparently, my watch lost 1 hour for some reasons.
So another question went off the top of my head is: Am I kidnapped by an UFO? People say if you kidnapped by aliens from another time-space you would lose hours of time. But as a well-educated and not crazy person, I vetoed this idea in the next minute as well.
Then I realized that it might be something to do with the daylight saving time. I checked it, and yes it was. I was relieved that I wasn't crazy or kidnapped. There is a synchronizing mechanism in my laptop and cellphone, so they adjusted the time automatically, but not my watch. And I was happy that I have an extra hour. It's interesting, just likes going back time. 11月1日 Analyse of My Personal EconomyAnalyse of My Personal Economy

Abstract
In this paper, we discuss the income and expend of a typical engineering North American international grad student, which is, me. This study shed a light on the future life of studying aboard for Chinese students, which is, still me.
Introduction
I could win a Nobel Prize by this paper.
1.Expend
1.1 Food: ~150$ [1]
1.2 Health Insurance: ~50$ [1]
1.3 Rental: ~360$ [2]
1.4 Other Expend: up to 150$ per month so far (It's a loose upper-bound.) [3]
1.5 Tuition per month: ~6400$/12~533$ [1]
So the summation is: ~1243$
2.Income
2.1 Scholarship+TA: ????$ (protected by commercial reason) [4]
3.Advantage
3.1 Net income: x=????$ - 1243$=???$
3.2 My monthly income in China: y=???$ [3]
Subsequently, we have: x>y.
Conclusion
Not bad.
