Curious HO

(HO and HF are playing Hide-and-Seek at KAIST)


Nowadays HO keeps on asking. Most favorite question is "What's that?" This week, HO adds "Why?" and "What're you doing?" to the bag of repertoire. HO is already a fluent speaker, impressing me and HM quite often.

“저게 뭐야?” “왜?” “뭐해?” 이 세 가지 질문으로 하루하루가 끝이 없다. 아기에서 어린이가 되어 가는 것인가보다. 오늘 저녁에는 블럭을 15층 탑을 쌓기도 했다. 몇달 전만 해도 3층탑도 버거웠었는데...

Finally all papers of HF are accepted.


Finally all of HF's work are accepted to IEICE. This one will be published onto IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences. Now HF has nothing to publish. Very happy. Thanks to you again, sincerely.

하나, 둘, 셋. 저널 3연타가 이번 논문을 마지막으로 끝났다. 기쁘고 시원하다. 그동안 고생한 가족들에게 무척 감사할 뿐이다. 경제적으로 어느정도 성취를 이루면 다시 연구를 해 볼까... 하는 생각이 잠시 들었다.

When HO goes to college...

If HO is about to enter a college, I would recommend a following article. This article may read dull as a textbook and HO may not be moved by first reading. But remember, HO,  that twenty years after entering college, your father thinks that it would have been great if whoever had recommended this article to me that day. You may think that you can reason and decide well enough by yourself. But even if you're right, taking advice can help you more.

Listen. There is a well-known proverb, "Practice makes perfect." Basically practicing means  doing the same thing over and over again (to excel). But there is another famous quote of Albert Einstein, "Insanity is doing the same thing over and over again and expecting different results." Contradiction? No. To expect better results, to excel in doing something, we should not only do something over and over again but also consider changing our approach if not successful. Deciding whether to go on or not and change approach is THE key, which is not an easy stuff. Wisdom is needed here, and usually wisdom seldom found its position in youth. Trust me, HO.

And you should exert yourself to get a good grade, for getting good grade will give you a habit of excelling. The habit of excelling, it's one of the most important thing you should get in your college life. Stanley J. Idzerdia said that "The habit of excelling is more important than the specific major field one takes in college."

What You Can Get from a College Education
by Roger W. Holmes

Now that you are in college and going to classes, pause long enough to ask yourself why we are teaching and you are learning. In spite of what you may have heard from us, your high school teachers, or your parents, the answer is not that we know the final answers to the problems we are discussing. We are teaching because we have carefully studied subjects in which you are a beginner, and because we have had more worldly experience than you. But neither of these facts makes us omniscient. If the truth be known, there are those of you in our classes who are more intelligent than we are--who will outstrip us in our chosen fields. Question us. Doubt us. Raise objections. Make us think! Avoid us when we measure your achievement in terms of the proximity of your thinking to our own. Welcome us when we admit that we do not know the answers to your questions, when we help you to find your own answers, when we encourage you to consider views with which we do not agree.


Why are you going to college? Not to enhance your parents' social position, not to get high marks; not to get the ultimate answers, which not even we can furnish. To use our own professional jargon, you come to college to get a liberal education. We must admit we do not altogether know what a liberal education is, but we have some fairly good ideas on the subject. We do not entirely follow these ideas. None of us, for example, believes that there is a magic in piling up a certain number of hour-credits. Yet, sixty credits and you get your diploma. And that diploma is supposed to admit you to the company of educated men and women. Why not fifty-five, or sixty-five? We do not know. Indeed if you pressed us, we should have to admit that some students are liberally educated with thirty credits while others will not belong to the educated company if they take sixty times sixty hours of credit. Do not measure your education by simple arithmetic.


Elect your courses with care. If you go to a college which requires that you juggle five courses at once, you will do well to find on easy berth and sleep in it; otherwise you cannot do justice to the other four. This is a secret practice accepted by all. But, in general, easy courses should be avoided simply because they are easy and do not give you your father's money's worth.


Do not select your courses with an eye for a specific job or type of occupation. More of you will make this mistake than not, and it is one of the most serious you can make. In the first place, we know at least that a liberal education involves a balance and harmony of interests. Secondly, your interests and talents are by no means fully appreciated or explored when you come to us. You do not want to wake up in your senior year and wish that you had not missed many important and interesting things. Thousands of seniors do.


When you come to college you are intellectually very young and have not yet learned to proceed safely or efficiently under your own intellectual power. You are what your environment and your elders have made you. Your ideas are not your own. The first thing you must learn is to stand on your ideas. This is why you should not take us and our ideas too seriously. Broaden your horizon so that as 'you become more and more able to take care of yourself you will move intelligently. Try to encounter the major point of view represented by the faculty and among the students. Entertain them the more seriously, the more they differ from your own. You may return to your own, but if you do it will be with greater tolerance and a broader understanding.


You come to college to gain a liberal perspective. In gaining this perspective, you must come to know the nature which surrounds and compels you, the society with witch you must live and cooperate, the creative spirit which is your heritage, and the tools of language and of thought. To express it in this specific manner is helpful. It suggests certain intellectual virtues which you must possess before you can be considered an educated man or woman. This does not mean that there are particular course solely for its specific content.


For example, we have said that you must come to know the natural world. This does not mean that you must study physics and chemistry and geology. It means that you must acquire the scientific attitude, understand the atmosphere and significance of the exact sciences, know their fundamental assumptions, their key concepts, their major contributions. And the same is true of the biological sciences. A course in botany or zoology or physiology or psychology is enough to give you an understanding of the important aspects of biology. You should get into the laboratory while you are in college, and you should work in both the exact and the biological sciences.


You want also to know the society with which you must live and cooperate. One of the ways in which you want to know it is the historical. You must be historically minded. You must recognize the importance of the past for the present. Man learns by experience, and history is social experience. Greek, Roman, European, American history--you cannot study them all, but you can become historically minded. And you can become socially minded in your view of the present world. Economic, social and political force have your world in their grips. You must study these forces, measure them, evaluate them.


Our heritage in the field of the arts has always been recognized as liberal. Not so much need to urge you here. Most of the greatest interpretation of human living is to be found in painting, sculpture, music and literature. What are some of the things which the great creative geniuses have told us about ourselves? What are modern artists trying to do? You must find our these things, not just that you may go to museums and concerts, but that you may want to go to museums and concerts. Elect some art or music, for pleasure, but also to increase your knowledge. Also, get a full and enthusiastic knowledge of the literature of your mother tongue. You will have discovered a source of wisdom, good taste and pleasure. Such studies need no recommendation.


Finally, you must come to understand the tools of language and of thought. And here urging is necessary. You ought to know another language, ancient or modern, inflected or non-inflected, so well that you dream in it. Such knowledge gives a far better understanding of your own tongue, both as a tool and as an art, than you could otherwise obtain. And you will have open to you another literature. Furthermore, you should be conversant with the structures and power of thought as an intellectual tool, and you should be willing to examine fundamental assumptions. Mathematics, logic and philosophy are helpful here. You may think them difficult, but do not avoid them altogether.


If you will examine this program for the enlargement of your intellectual horizon, you will see that it involves some eight subjects spread throughout the departments of your college. It is a program which you can complete in your freshman and sophomore years and one which you should carry through in order that you may be equipped intellectually to proceed to the second part of your college education. It will give you necessary breadth.


But you must also specialize, when the foundation has been laid. You must do this not because specialization will prepare you for a specific job, but because a certain degree of specialization is the second essential of a true intellectual endeavor. Without specialization your college work is in danger of becoming that thin veneer of "culture" which we all recognize as superficial. And now you will find the faculty more cooperative. We are specialists and we like to encourage specialization. But still be on your guard, for we shall mislead you by overemphasizing the importance of our particular little corners of learning. The important matter is not what you specialize in, but that you specialize. Specialize in anything but your subject of graduate study. If you are going into medicine, you might major in history. If you will be a lawyer, major in art or music.


Even your specialization should be carefully planned. In the first place, it will probably be advisable for you to do advanced work in each of the four major fields of study: natural science, social science, art and literature, and language, mathematics or philosophy. If you studied chemistry as a freshman, you might go on to more advanced chemistry and take elementary astronomy or geology as complementary work. In short, in each major field in which you took two elementary courses as an underclassman, you should follow one elementary course into advanced work and at the same time gain some knowledge in a complementary field.


But this will take only half of your time as an undergraduate. You should devote the other half of your last two years to intensive specialization in one subject in which you have the greatest interest and for which you have shown marked talent. Perhaps you have found history the most absorbing of subjects. Good! Go on it. Devote half of your junior and senior years to history. Show that you can work intensively on the details of your chosen major, manipulate these details correctly, and fit them into a comprehensive picture of the whole. But remember--though your teachers will work against you here--you are studying primarily for the sake of the intensive specialization and not of the history. Your roommate is getting the same thing from majoring in mathematics or English literature.


When you have avoided the Scylla of heterogeneous meanderings among elementary facts and concepts and the Charybdis of a study so narrow that you are ignorant of what is going on outside your own little corner of interest, you will have intellectual balance and perspective. Do not take us as your models. We represent a special world and we are an academic people. You are going into a broader world and a non-academic environment. Make us realize that our interests and understanding should spread into every field. Make us see that our students are at least as important as the subjects we teach. Make us understand that marks and examinations are more administrative conveniences to be taken far less seriously than we take them. In short, insist that we get together as a unified organization and provide you with a liberal education. Strength to you! If you will do these things you will be performing a service to us and to yourselves.

Best Professors

EBS, Educational Broadcasting Station, have aired a documentary series named "Best Professors", and now published a book with same name. It's a coincidence that EBS aired and published about what the best teachers do and I(HF) got curiosity about learning and teaching.

This book holds interviews with eight professors. They might not be great proferssors. But their words on the book convinces me that all they have philosophy in teaching and devote themselves in teaching.

All the professors are different. However, I found that all they put their efforts in teaching, treating teaching as never easy job even after many decades of experience. I'm certain that they might have been able to keep going the teaching job because they have enjoyed it.

EBS 다큐멘타리 '최고의 교수' 책을 읽었다. 무심코 들렀던 서점에서 발견한 책. EBS에서는 참으로 양질의 컨텐츠를 많이 만드는 구나. 훌륭한 사람들이다.

일종의 결벽증 탓에 책을 읽을때 책에 줄을 긋지 않고, 귀퉁이를 접지 않아왔다. 좋은 책이라 느끼면 여러번 보리라 라는 생각에 그리하여 왔는데, 실상 여러번 본 책은 그리 많지 않다. 이 책을 보다보니 교수들의 이야기 중 기억하고 싶은 이야기가 많아 책을 접어가며 보았다. 이제 나이도 어느정도 먹었으니 앞으론 계속 접어가며 봐야 할 듯 하다. HO는 아예 처음부터 책을 접어 가며 보도록 해야겠다.

접은 곳이 무척 많으니 맨 앞과 맨 뒤의 이야기를 적어 본다.

"내가 가장 중요하게 생각하는 원칙은 세심하게 들어주기, 그리고 명확하게 말해주기이다." - Charlie Cannon


"사실 자기 자신조차 완전히 통제하지 못하는 평범한 교수들에게 최고의 교수들이 보여준 모습들은 다소 벅차게 느껴질 수도 있습니다. 그러나 우리는 누구나 최고의 교수가 될 수 있습니다. 분명 충분히 시도해 볼 가치가 있고, 또 성취 가능한 일입니다. 어쩌면 가장 큰 장애는 우리의 경직된 사고와 편견일 거예요. 교육자로서의 자질은 타고나는 것이며, 우리가 어찌할 수 없는 일이라는 생각 말이죠." - Ken Bain

Advising Students for Success

I stumbled onto these two articles, "Advising Students for Success" from Dr. Ullman and "Your Students Are Your Legacy" of Dr. Patterson. Since HO came into my life, I've always had a question that how can I teach her into better being. My road to Ph.D. also ignited sparks on the question. How can people can think, invent, and express something well, enough to satisfy theirselves? Those two articles are worth reading.

However, I enjoyed the following part aside from Dr. Ullman on students and startups:
".. while getting a doctorate and entering the research arena is a high calling, it is not the highest possible calling. A startup can hace more impact on our lives than a thesis."
The following part from Dr.Patterson's is also good.

".. What I learned from the book was that people were happy with their careers if they designed or built objects that lasted, such as the Empire State Building or the Golden Gates Bridge, or if the shaped people's lives, such as patients or parishioners. Thus, I went into the job of assistant professors with the hypothesis that my long-lasting impact was not the papers but the people."


필립 웨이들러 교수의 블로그에서 본, 이번달 CACM의 글이다. 졸업을 하고 나니까 더욱 어떻게 해야 연구를 할 수 있고 논리적인 생각을 할 수 있나에 대한 궁금증이 촉발된다.

HF's Kinesis Layout

After experimenting a while, I fixed the key layout of my Kinesis Advantage keyboard. (1) To keep compatible with other keyboards, backquote key goes there. (2) To save left pinky during emacs and bash session, left control key goes to left thumb position. (3) For backspace key I followed Colemak layout. (4) For equal key, I put it at strange position not to have my brain confused. (5) Since alt key is my emacs meta key, I put it near left thumb enough to reach easily (6) For window manager hot key, I allocated two Mod keys and put those into thum positions. (7) Standard position of ESC key is too far for my pinky to reach. I put it into thumb area. (8) Though I do not use del key frequently, I put it into thumb area for emergency situation. (9) Caps lock key and International key is needless. So I eliminate those.

Bad Samarithans

Bad Samaritans: The Myth of Free Trade and the Secret History of Capitalism
Ha-Joon Chang (이순희 역)

This book is a page-turner. I hope I could write like this book somedays.

Prof. Chang criticized the selfish behaviour of strong countries which advocate 'free trade'. Free trade is not beneficial for the most of developing countries, he said, and the countries advocating free trade have made their wealth using 'protective trade,' not free trade.

His view might be correct or not. It might not be only one definite answer to a social science problem. So, there is no point arguing over what the book describes. What makes this book outstanding is how the book tells the story: (1) The book does not blindly accept common belief, the myth of free trade in his word. Challenging common belief takes courage. This book is courageous. (2) The book is logical. His opinion is backed up by many examples. (I think that there might be many counter-examples he did not want to mention.) The logic of the book flows well, continuously. (3) The book has a story Dr.Chang wants to tell us. If a book does not have a story threading entire parts, it becomes boring and distracting. Even the book has a story, it could be quite difficult to avoid the feeling of 'academic paper' or 'the listing of non-related facts' for the book of economy. (4) Dr.Chang told us the story well. He is a story-teller. Several chapters deals various aspects of the pitfalls of free trade without losing central theme. This book becomes a page-turner by his excellance in story telling, not by its own themes alone.

I heard the news that Obama U.S. administration might bring certain degree of 'protective trade' again to deal with the sink of U.S. economy. The reason of why this book gets spotlights, why Dr. Chang gets interview from worldwide radio show, why it might be worth of reading the book may reside in the news.

졸업식 이후에 감기로 약 일주일동안 아팠다. 아팠던 덕택에 느리게 읽었고 제대로 읽지 못하였지만 그래도 일단 일독.

'선진국들이여, 자유무역이란 기치하에 개발도상국으로의 약탈을 그만하라. 결국 개발도상국이 잘 되어 전체 경제규모의 파이가 커져야 너희들도 좋을 것 아니겠는가!' 라는 이야기이고, 읽는 내내 상당히 동감하면서 읽었다. 이런 책을 내놓을 수 있었던 장교수에게 감탄하였다. 일반 통념에 의문을 품었고, 반대를 위한 반대가 아니라 신념에 의한 반론 및 대안을, 일반 독자를 대상으로 부드럽게 풀어 나간 일 - 쉽지 않음을 알기 때문이다. 우리가 사는 모든 시공간이 약육강식의 논리로부터 피할수 없음을 다시금 일깨워주면서, 항상 깨어 있으라는 메세지를 간접적으로 받았다. 좋은 책이다.

추신. 한글판 포맷이 상당히 마음에 든다. (글꼴, 각주, 색감등...) 혹시 책 작업을 할 일이 있다면 참고할만한 책.

Kinesis Advantage contoured keyboard


I changed the keyboard on work from Atessa Clear 101, which is a wonderful keyboard, to Kinesis Advantage contoured keyboard. I've enjoyed having better keyboard always. Atessa Clear 101 was the definitely best one and I have been with it for more than 5 years. But nowadays I'm changing everything. (my family is only exception :-) ) My beloved Atessa does not escape from my changing rush.

Bill Clementson of Lisp community wrote an article in his blog about Kinesis and I'm sold on the article. Now I'm facing Kinesis. It's like a wild horse. I'm very curious how far she can go.

The figure is current keymapping, by Allen Day.

Family came and congratulated. Thanks all.

President Myoung-Bak Lee appeared in the ceremony, as the following photo. One with red costume is Nam-pyo Seo, the dean of KAIST. HF was there. Now he is Ph.D. :-)

졸업했읍니다. 1989년 대학입학이후 20년만의 학위취득. 마냥 좋았지만 학부 졸업생들의 모습에 부러움도 느꼈습니다.
