0920 when I was heading on Seoul in the bus to meet my friend
Writing a diary when I was on the but yesterday======================================
Now, I feel like I am traveling the other city unlike that I am in Korea. As I remember, this feeling is a sort of when I went on trip in Toronto from Montreal two years ago because I am listening with classical music without thinking of anything stressful, which was same as the time in Montreal.
Actually, it tells me how awesome my foreign experience was with many people cheering me out. When I think of Canada, especially Montreal, I tend to not consider what surrounds me now. This is largely because I could do whatever I wanted do when I was there. For example, generally speaking, drinking a lot is always harmful factor to human beings. It can make people sick and lost a part of memory called a black out. However, I drank a lot with my Montrealer friends, It felt like my condition was getting better than when I was in Korea before going there. I might be guessing the reason. It is probably, compared to my past life in Korea, I can tolerate anything burdensome and pressure in Montreal due to the fact that all I did is what I wanted to as I pointed out.
For some reason it is not beneficial to miss the past without recognize the present.
According to my relative experience, I am sort of the person who miss or reminisce precious memory when I am emotional. Some peoples close to me told me it is really good personality or character to feel emotionally something, whereas others it can bother what you have to do and determine something important.
Who knows the truth? There is a chance that Montreal life led me to achieve many things precious to me after I was back to Korea. This is true for me to thrive in much intolerable thing when I dream of the Old Port of Montreal where I used to go two years ago in order to forget something tough.

Python
- Source code does not declare the types of variables or parameters or methods.
- When a Python file is run directly, the special variable "__name__" is set to "__main__". Therefore, it's common to have the boilerplate if __name__ ==... shown above to call a main() function when the module is run directly, but not when the module is imported by some other module.
-We also presented 2 different ways to repeat strings, using the + operator which is more user-friendly, but * also works because it's Python's "repeat" operator, meaning that '-' * 10 gives '----------', a neat way to create an onscreen "line."
- We hinted that * works faster than +, the reason being that * calculates the size of the resulting object once whereas with +, that calculation is made each time + is called.
- One unusual Python feature is that the whitespace indentation of a piece of code affects its meaning.
- A logical block of statements such as the ones that make up a function should all have the same indentation
- The funny thing in Python ... this code compiles and runs fine so long as the name at runtime is not 'Guido'. Only when a run actually tries to execute the repeeeet() will it notice that there is no such function and raise an error.
- In this way, various Python modules can name their functions and variables whatever they want, and the variable names won't conflict -- module1.foo is different from module2.foo.
- You can find the documentation of all the Standard Library modules and packages at http://docs.python.org/library.

0907 A lot of things are coming to my mind, these days.
0906 Right before Korean Thanksgiving Day
Right Before Korean Thanksgiving Day
Last night, before meeting my friend at midnight I did many things for what to do on holiday, Chuseok. In detail, I installed 'Hadoop cluster' system through Putty, free ssh program, on server which is in my lab. Still, I was really stupid. Actually, to set up the environment to connect server through putty, I learned many thing to do it via a lot of blogs. However, I changed a port without no definite idea. That's because I felt like I had to change the port 80 to 22 when I saw this message from Hadoop 'localhost of which a port is 22 cannot connect to server'
In fact, I should not have done it because my school, KAIST, already blocked a port 22 to block a would-be malicious user connecting to school's server. I was just out of brain. Now, I cannot connect my server and cannot do anything to learn and analyze codes of Hadoop. It was my plan on holiday.
Damn........
Thus, I set my heart to study a textbook of Hadoop just formally
0901 My first essay in September, 2010
In my life, 'Psychopath' I respect at times
The most important things in my life is that we compete with myself, so we should win our timid mind that can disturb our future.
To do so, I think that we have to become 'Psychopath' from time to time. Most people consider 'Psychopath' as negative meaning. This opinion is fact, I don't think so that way.
There are more reasons why, buy I will just talk about some reasons of them. Let me explain why.
In my experience, I read a certain book relevant to Psychology before. At this point of time, I am sorry to you that I do not remember a book's name. These reading passage of book described 'Psychopath' as positive meaning. To be specific, psychopath that we consider as negative meaning is personality that cannot distinguish a diverse range of emotions, such as being sad, happy, gloomy, and so on. Thus, people often think psychopath can raise many crime and unpleasant things.
0831 Mentor talking about something important 0831 at night
Well, you do not know my mentor.
Actually, for me when I was in undergraduate, my father was a mentor for me.
In fact, I could say my mentor was really willing to changing me a lot.
That's why we got a bunch of troubles after talking about challenge things.
However, after graduating Kyung Hee University, FYI as a top student in my department, I was totally independent from my father. It was good for me to definitely stay alone.
Well, the truth is I have been independent from my parents since I got into military service after I was in the first year of Kyung Hee University.
Now, in the period of doing Master's Degree in Kaist I feel like I respect two of people as mentors in my life; one person who is my senior two times, the other person who I knew in an academic video.
Okay, cut to the chase.
According to him, a firm has a limitation of doing good things alone. When the firm cooperate with the other company, the result, the quality of goods and service would be better then that of doing alone. It means that it can be more competitive.
"What do you think is Business alliance?"
To achieve this, we should have negotiating power!.
In fact, there are many exceptions like its size, its kind, its period and so on among partnership, so contract sometimes disappear right away or last long.
The most important thing between partnerships is all the companies win.
p.s) bringing English material from my home.
Thing are goin on 0831
My first vacation in the period of Master's degree is almost done.
It just has two days to left.
Actually, I suddenly watched a random video about Google's employee working in silicon valley. I got inspiration from there. You know the word, 'inspiration" is always Good!
I had something that came to mind while watching the video.
I realized I changed a lot compared who I was in the second year of high school.
Well, I was really willing to try to enroll in the great university. That's why I did totally my best at that time. Plus, compared to who I was right after serving military service, I am definitely lazy of thinking or doing.
I've never thought I can being lazy for more than one year.
Now, I got this. I have been becoming lazy since I got into KAIST.
It seems very weird because I entered into the best school in Korea after I did my best before coming here. Still, my thought was just desperate.
However, the most important thing is that, you know, I do not regret this time.
the matter is just now, meaning the bright future is just depending on my attitude towards things surrounding me.
0831 after watching "스타특강"
Keywords, today) Mailing to him, Scheduler, Hosting attitude, To pick me up, Story line when I present something, Blogging, Social networking to people associated with my field.
I spent too much time on installing Eclipse and SDK, today 0820
This is really shit, isn't it?
You can imagine how annoying it is just to install a program even though I already knew how to do it.
Two days already passed but I have a lotttt of works now.
Life is wonderful, huh?
