"Stay Hungry, Stay Foolish"
This is a talk of Steve Jobs at Stanford Commencement,2005.
His third story reminds me me about a chapter in the book "The 7 habits of highly effective people", by Stephen Covey. They both advice us to "begin with the end in mind". Think about "death" to live with all our love, our passion today, but I prefer the word "the end" than "death".
With "the end", I can apply this idea on many contexts. At night, I can ask my self what I want to be done by tomorrow? Usually, many plans come up for this answer, many sometimes mean "more than enough for a day". But in those plans, there is nothing like "1 hour sitting and thinking of nothing", "1 hour lazy and not wanting to do anything on a half day",... In a context of a year, do I have have any plan? Yes, I do. How about 10 years, 20 years? Yes and yes!
I find it surprising here when I use the word "plan". I have a "plan" for today; but what about in 5 years or ten years or longer. Not much specific, but just think about "what I want to have or to be". I do not have any clear "plan" to achieve those goals. How can I get my destination if I don't have a map, and don't "plan" which roads I should take and which directions I should turn?
This talk prompts me to think about the connection between: "the end"+"plan". Nice talk! Especially love his idea "Stay Hungry. Stay Foolish."

Approximation Algorithms
http://www.cs.uiuc.edu/homes/chekuri/teaching/fall2006/approx.htm
2. Using primal dual method for Approximation Algorithms, a good survey by David P. Williamson
The primal-dual method for approximation algorithms and its application to network design problems
3. Using Local Ratio method for Approximation Algorithms, a survey by Reuven Bar-Yehuda, Keren Bendel, Ari Freund, and Dror Rawitz
Local ratio: A unified framework for approximation algorithms
4. Some time it seems that whatever way we try, we just can find a approximation. Well, maybe computing good approximation for that problem is also NP-hard. To prove the hardness of approximation, following documents are good starting point:
A survey by Sanjeev Arora, and Carsten Lund
Hardness of approximations
Another one by Luca Trevisan

The Great Circle of Viet Nam
The Great Circle of Viet Nam
(translated by Richard Fuller)1. From jungled hills to the distant sea,
We form a giant circle to unite our country.
From far and wide, we now return,
With joy, like a sandstorm, to the far horizons,
Let's now join hands :
A great circle of Viet Nam
Flags in the wind, happy nights and days,
Of one blood our hearts ablaze,
Reconciled, a new day.
Hamlet, town now joined as one,
Remember the dead as we bask in the sun,
And one by one, we spread our smiles.
2. From North to South, we all join hands,
From fields long abandoned to mountainous lands,
We'll ford deep streams, climb over hills.
From hamlets to the cities,
We embrace with glee an eternal circle :
Dead and living, one are we.
Nối vòng tay lớn
(Trịnh Công Sơn)
Rừng núi dang tay nối lại biển xa
Ta đi vòng tay lớn mãi để nối sơn hà
Mặt đất bao la anh em ta về
Gặp nhau mừng như bão cát
Quay cuồng trời rộng bàn tay ta nắm
Nối tròn một vòng Việt Nam
Cờ nối gió đêm vui mỗi ngày
Dòng máu nối con tim đồng loại
Dựng tình người trong ngày mới
Thành phố nối thôn xa vời vợi
Người chết nối linh thiêng vào đời
Và nụ cười nối trên môi
Từ Bắc vô Nam nối liền nắm tay
Ta đi từ đồng hoang vu vượt hết núi đồi
Vượt thác cheo leo tay ta vượt đèo
Từ quê nghèo lên phố lớn
Nắm tay nối liền biển xanh sông gấm
Nối liền một vòng tử sinh.

A gift
This is a gift from "someone". I love it very much. Every day, I put those marigolds in front of the house, before I go to school, so that they can enjoy summer's sunshine. In the late afternoon, I water them when I come home. Then, I bring them to the porch, behind the living room door. There, they can enjoy sunset (and I can gaze at them). Wait and see how they will grow up.
Thanks "there" alot :)
Yah, now you should come here and see I have done good job

I went to NYC some times, enjoyed broadway shows, bars, shopping, having dinner on boat tour; but NYC haven't , really, attracted me much. Even though I am living close to NYC now, it is very convenient to catch a train to there; but it's the last thing I want to do, I guess.
Last week, I were there with 3 friends for a special day, Independence Day. After walking, watching, eating around for almost whole day, finally we settled down for fireworks . We sat on shower curtain, played cards, and ate tons of fruits IN THE RAIN. It's fun to play cards, and hold an umbrella at the same time :)
The fireworks weren't as beautiful as I expected,but didn't matter. We had something to remember :)

stir-fried shrimp with black bean
Time: 30 minutes
Ingredients
2 tablespoons fermented black beans, sold in Asian markets
2 tablespoons dry sherry or white wine
About 1 1/2 pounds uncooked shrimp, in the 20 to 30 per pound size range, peeled
1 1/2 teaspoons sugar
2 tablespoons soy sauce
1 clove garlic, sliced, and 1 tablespoon minced garlic
1 teaspoon salt
2 teaspoons dark sesame oil
1 pound bok choy or other cabbage, trimmed, washed and dried
2 tablespoons peanut or vegetable oil
1 tablespoon peeled and minced or grated fresh ginger
3/4 cup chicken stock or white wine, optional
1/4 cup minced scallions.
Directions
1. Soak black beans in sherry, wine or water. In large bowl, marinate shrimp in

2. Separate bok choy leaves from stems; chop stems into 1/2 - to 1-inch pieces, and roughly chop leaves.
3. Preheat a wok or large skillet over medium-high heat. Add 1 tablespoon peanut oil and raise heat to high. When it begins to smoke, add minced garlic and, immediately thereafter, shrimp and its marinade. Cook shrimp for about 2 minutes, stirring occasionally. Spoon it out of wok or skillet.
4. Put remaining peanut oil in wok or skillet and, when it smokes, add ginger, followed immediately by bok choy stems. Cook, stirring, until bok choy is lightly browned, 3 to 5 minutes, then add leaves. Cook, stirring, for 1 minute, then add 3/4 cup water, stock or white wine and let it bubble away for a minute.
5. Return shrimp to wok or skillet and stir; add black beans and their liquid, scallions, and remaining sugar and soy sauce. Stir and cook for 1 minute. Turn off heat, drizzle remaining sesame oil on top, and serve.
Yield: 4 or more servings.
