đôi mắt người sơn tây – 2

Tác giả của: Tây Tiến, Đôi bờ, Đôi mắt người Sơn Tây, Mây đầu ô, Quán bên đường

ản nhạc không ngưng trở đi trở lại gây nên trong tôi những cảm xúc khó tả… Từ lần nghe đầu qua giọng ca chính tác giả Phạm Đình Chương – Hoài Bắc, đến những trình bày khác sau này, vẫn bàng bạc cái tâm trạng: thoáng hiện em về trong đáy cốc, nói cười như chuyện một đêm mơ. Có lẻ trong tâm tưởng mỗi con người, mỗi nghệ sĩ đều phảng phất đâu đó một không gian tôi nhớ xứ Đoài mây trắng lắm, một cõi xa vời đầy chất tưởng tượng huyễn hoặc, đã từng (hay chưa từng?) tồn tại, un paradis perdu – một thiên đường đã mất.

Đôi mắt người Sơn Tây - Hoài Bắc 
Đôi mắt người Sơn Tây - Thái Thanh 
Đôi mắt người Sơn Tây - Bích Liên 

Có nhiều người đã thể hiện ca khúc này, từ chính tác giả Phạm Đình Chương, bác sĩ Bích Liên, đến ca sĩ Quỳnh Giao. Nhưng hay nhất có lẽ vẫn là NGƯỜI ĐÀN BÀ HÁT – Thái Thanh, đây là bản thu âm lúc bà còn trẻ, khi chất giọng hãy còn căng đầy những luyến láy, những thăng giáng tinh tế. Hãy nghe lại giọng ca của bà, một loại tiếng Việt đã “tuyệt chủng”, hãy nghe để thấy tiếng Việt ngày nay đã trở nên nhanh hơn, phẳng hơn, truyền tải nhiều thông tin hơn, và ít nội dung hơn, phần nhiều là những loại ôm rách nát không tâm linh, ôm tiếng hát không hơi rung nghèo nàn.

bài thơ đầu tiên

ài thơ đầu tiên tôi thuộc, một cái học thuộc lòng “cưỡng bức”, trước khi biết đọc, biết viết. Ngay cả trước khi biết nói cho rành mạch, rõ ràng thì tôi đã nằm lòng hơn trăm câu của Chế Lan Viên này. Đơn giản là từ lúc nằm nôi thì tôi đã được (bị) ru bằng bài thơ này mỗi ngày, đến nỗi thuộc như cháo lúc nào không hay, ví dụ như: Ôi Trường Sơn vĩ đại của ta ơi, Ta tựa vào ngươi kéo pháo lên đồi… hoặc là: Ôi thương thay những thế kỷ thiếu anh hùng, Những đất nước thiếu người cầm thanh gươm nghìn cân ra trận…

Bản dưới đây là chép lại theo trí nhớ của tôi nên có đôi chỗ khác biệt với bản hiện đang phổ biến lưu hành. Đó là chuyện của một thời (một thế hệ) đầy lý tưởng (ảo tưởng!?), còn đây là chuyện của thời bây giờ, đề thi Văn năm nay nên ra như thế này:

Hãy điền chữ còn thiếu vào đoạn thơ sau
(liệu hồn mà điền cho đúng):

Hỡi sông Hồng tiếng hát bốn nghìn năm,
Tổ quốc có bao giờ …… thế này chăng?

😬

Tổ quốc có bao giờ đẹp thế này chăng – Chế Lan Viên

Hỡi sông Hồng tiếng hát bốn nghìn năm!
Tổ quốc có bao giờ đẹp thế này chăng?
Chưa đâu! Và ngay cả trong những ngày đẹp nhất,
Khi Nguyễn Trãi làm thơ và đánh giặc,
Nguyễn Du viết Kiều, đất nước hóa thành Văn.
Khi Nguyễn Huệ cưỡi voi vào cửa Bắc,
Hưng Đạo diệt quân Nguyên trên sóng Bạch Đằng.

Những ngày tôi sống đây là những ngày đẹp hơn tất cả,
Dù mai sau đời muôn vạn lần hơn.
Trái cây rơi vào áo người hứng quả,
Đường nhân loại đi qua bóng lá xanh rờn,
Mặt trời đến mỗi ngày như khách lạ,
Gặp mỗi mặt người đều muốn ghé môi hôn.

Cha ông xưa từng đấm nát tay trước cửa cuộc đời,
Cửa vẫn đóng và đời im ỉm khóa.
Những pho tượng chùa Tây Phương không biết cách trả lời,
Cả dân tộc đói nghèo trong rơm rạ,
Văn Chiêu Hồn từng thấm giọt mưa rơi!

Có phải cha ông đến sớm chăng và cháu con thì lại chậm?
Dẫu có bay giữa trăng sao cũng tiếc không được sống phút giây này.
Buổi đất nước của Hùng Vương có Đảng,
Mỗi người dân đều được thấy Bác Hồ.
Thịt xương ta, giặc phơi ngoài bãi bắn.
Lại tái sinh từ Pắc Bó, Ba Tơ.

Không ai có thể ngủ yên trong đời chật,
Buổi thủy triều vẫy gọi những vầng trăng.
Mỗi gié lúa đều muốn thêm nhiều hạt,
Gỗ trăm cây đều muốn hóa nên trầm.
Mỗi chú bé đều nằm mơ ngựa sắt,
Mỗi con sông đều muốn hóa Bạch Đằng.

Ôi Trường Sơn vĩ đại của ta ơi!
Ta tựa vào ngươi, kéo pháo lên đồi.
Ta tựa vào Đảng ta, lên tiếng hát,
Dưới chân ta, đến đầu hàng Đờ-cát.
Rồng năm móng vua quan thành bụi đất,
Mỗi trang thơ đều dội tiếng ta cười!
Đều lộng hương thơm những cánh đồng hợp tác
Chim cu gù, chim cu gáy xa xa.
Ruộng đoàn tụ nên người thôi chia cách,
Đêm no ấm, giọng chèo khuya khoan nhặt,
Lúa hên mùa xin lúa chín về quê ta.

Rồi với đôi bàn tay trắng từ Đinh, Lý, Trần, Lê…
Đảng làm nên công nghiệp.
Điện trời ta là sóng nước sông Hồng.
An Dương Vương hãy dậy cùng ta xây sắt thép,
Loa thành này có đẹp mắt Người chăng?
Ong bay nhà khu tỉnh ủy Hưng Yên,
Mật đồng bằng mùa nhãn ngọt môi em,
Cây xanh ngắt đất bạc mầu Vĩnh Phúc.

Ôi cái thuở lòng ta yêu Tổ quốc,
Hạnh phúc nào không hạnh phúc đầu tiên?
Ôi cái buổi sinh thành và tái tạo,
Khi thiếu súng, khi thì thiếu gạo,
Nhưng phù sa này đẻ ra những Cà Mau,
Thịnh vượng mai sau.

Dẫu là Chúa cũng sinh từ ruột máu,
Ta đẻ ra đời, sao khỏi những cơn đau?
Hãy biết ơn vị muối của đời cho thơ chất mặn!
Ôi thương thay những thế kỷ thiếu anh hùng,
Những đất nước thiếu người cầm thanh gươm nghìn cân ra trận,
Nhà thơ sinh đồng thời với mưa phùn và những buổi hoàng hôn.
Cả đất nước trắng một màu mây trắng,
Ai biết mây trên trời buồn hơn hay thơ mặt đất buồn hơn?

Chọn thời mà sống chăng? Ta phải chọn vào năm nào đây nhỉ?
Cho tôi sinh ra vào giữa buổi Đảng dựng xây đời,
Mắt được thấy dòng sông ra gặp bể,
Ta với mẻ thép gang đầu làm đứa trẻ sinh đôi,
Nguyễn Văn Trỗi ra đi còn dạy chúng ta cười.
Cho tôi sinh ra giữa những ngày diệt Mỹ,
Vóc nhà thơ đứng ngang tầm chiến lũy,
Bên những dũng sĩ đuổi xe tăng ngoài đồng và hạ trực thăng rơi.

thuyền viễn xứ – 2

ột bản nhạc càng hay thì người ta càng tìm cách diễn dịch nó theo nhiều cách khác nhau, một cảm hứng, gợi ý ban đầu cho nhiều trình diễn, chuyển soạn, phát triển… Như bản Thuyền viễn xứ, có không biết bao nhiêu là người trình diễn, tôi đã nghe nhiều, vocal cũng như instrumental, nhưng tiếng đàn bầu dường như vẫn là, một cách tự nhiên nhất, thanh âm phù hợp để truyền tải cái hồn của Thuyền viễn xứ.

Thuyền viễn xứ - Thái Thanh 
Thuyền viễn xứ - Quỳnh Giao 
Thuyền viễn xứ - Văn Vượng (guitar) 
Thuyền viễn xứ - Phạm Đức Thành (đàn bầu)

bare feet, iron will

ne more item in my to – be – read list: Bare Feet, Iron Will, by James Zumwalt, a retired Marine lieutenant colonel, son of the Vietnam war’s time US Navy’s Admiral. The book has recently been translated and published in Vietnamese. Though I haven’t got an English copy in hand, my interests rose after reading this interview with the author. Just like Archimedes Patti’s book Why Vietnam?, I would expect stories from intermediate – level officers to contains a lot of facts, events, numbers… that gives details into the things that happened, and offers closer, truer look into the figures involved, unlike those of high – level cadre supérieur (a.k.a politicians).

The author recently gave an interview with Vietnamese presses, in which he confirmed that his book was inspired by The sorrow of war, Bảo Ninh’s novel. He loves the novel and dedicates part of his book to write about this Vietnamese fiction and its author. I knew some 20 years ago that The sorrow of war would be a very profound impact (read more about it in my another post here). It’s just ridiculous that the VN government once forbade (and still limits) the novel, permits it to be appeared on news on occasions only to serve some political purposes, this time is a step toward tighter relation with the US. Below is some notable remarks from the author, James Zumwalt interviews:

Was the loss of a loved one any less significant just because it occurred on the other side of the battlefield? …It just opened my eyes to the fact that we have to recognise that our suffering is mirrored on other side.

When I made my second trip, one of the first places I went to was the Hanoi war museum. And there they had a section devoted to war criminals – one of whom was my father for his use of Agent Orange. (Asked: How did he react to being a war criminal?) He kind of smiled and said: Well it’s a good thing they didn’t arrest me when I was there.

In one case, a doctor told his wife he would probably be gone for six months to a year. He was gone for eight years, and only got back to visit his wife once… Many of those I interviewed had difficulty pinpointing particular years, but they could tell me if it was in dry or monsoon season. That was the way they looked at it. The year didn’t matter. That shows the mindset they operated under.

There were some 1,400 mothers who lost three or more sons in the war. I think we’d be hard pressed in this country to find more than a handful of mothers who lost more than one son in Vietnam. They considered it a sacrifice they had to make.

In the interviews I did with hundreds of NVA / VC I asked them what their motivation was. It was not communism but rather it was nationalism and the desire to reunify the country… I believe it is part of the Vietnamese people’s DNA. To them, there was never any alternative, they just had to prevail.

Look at the Vietnamese who defeated the Japanese in 1945, the French in 1954, the Americans in 1975, and again the Chinese in 1979, I don’t think we realised we were probably fighting against Vietnam’s own Greatest Generation. (yes we sacrificed our best seeds in those wars, you know what the sh… is left as of today! 😢)

the world is not flat

The book title reminds me of the same stupid question: how to put an elephant into a refrigerator. I still insist that you can not put a normal elephant into a normal refrigerator, no matter how people is arguing about that! The question: how to eat an elephant (answer: one bite at a time) actually makes more sense to me!

Friedman is right that there have been dramatic changes in the global economy, in the global landscape; in some directions, the world is much flatter than it has ever been, with those in various parts of the world being more connected than they have ever been, but the world is not flat… Not only is the world not flat: in many ways it has been getting less flat. (Nobel Prize – winning economist Joseph Stiglitz)

The popular expression that a capitalist will even sell you the rope you need to hang him with seems to be becoming increasingly true. Aronica and Ramdoo’s book is an important addition to the literature of globalization and a necessary therapy for all those whose minds have been in touch with Friedman’s glib phrases. (blogcritics.org)

would tell you how I usually encounter a dialogue taken place in Vietnamese, a pattern that repeats over and over again, and people never learns a thing, neither do they actually have a little sense about real things behind it. Here’s how the dialogue would go on, taken an example to describe the pattern: A (a certain person): I’ve recently read the book “The world is flat”, and really love it! Ah ha, the world is truly flat!   Me: No, the world is not flat!   A: I would suppose you don’t mean it geographically, think about it like a metaphor to get the philosophy of the book, man!   Me: No, the world is not flat!   A: You never get a thing, you crazy!

By now, anyone with a second thought should recognise my meaning either geographically or metaphorically. After that I asked him something into the content of the book. It turned out he knows almost nothing of the book except its name, and parrots the name as if he had found a “holy truth”! Yes I would certainly understand, while everyone was reading and everyone was saying the world is flat, he wouldn’t dare saying (or even thinking) the opposite. My opinion about the book could be right, or it could be wrong, but actually I won’t argue on the surface of phrases, flat or not flat is just a matter of words, what important is the book’s content.

I’d read through the more than 300 pages of the book which takes its examples, facts… exclusively in the Information Technology contexts, either in India, China or other Asian, Latin countries. It is full of details of only the IT industries, details about out – sourcing, internet, software work flow, email, network phone… the things usually seen in outsourcing service. Obviously the author meant a similarity for other fields, other industries, which seems to be a too restrictive point of view, we all know that IT in fact is only a very small fraction of the economy (taken the VN textile industry alone for an example, its estimated yearly revenue is roughly 12 ~ 15 times bigger than the IT counterpart).

The book concentrates on globalisation: the trends of out – sourcing, the way people communicates, the way firms process information… The author propagates it as “a way to be”, a trend, a life style that is absolutely irreversible. Also Friedman considers open source software the most disruptive force of all of the trends since it allows knowledge to be freely distributed and decentralised efforts could be cooperated. Friedman also encourages young American to become scientists, engineers, mathematicians… leaving low – level labour jobs to other countries. The author also tried to relate those vast details with other profound social and political problems.

I have never read anything so “colonial” like that book. It takes a lot of facts, truths… in a small sector of the economy and tries to provide a biased and exaggerated point of view. To exactly quote the author: When the walls came down, and the windows came up, windows can not come from thin air, there’re always “invisible” walls somewhere, and most of the times, those invisibles are much more overwhelming than the visible ones. In fact the book only receives “warm appreciations” in the field it’s related with, and aiming to, that is IT, it does tremendously receive negative reviews right in the country of its author (you can easily check out the web for that).

The world has never been flat, anywhere, anytime. It’s not flat in the sense of people about their living conditions and standards. It’s not flat in everyone’s mental and psychological status. It’s not flat in different life styles, in people’s hugely diverse definitions and pursuits for happiness. It’s not flat even in the American (or any Western) societies, whose tradition has always been the supporting for personal values, think and do differently. It’s not flat as human as a physical and mental objects are bounded to geological and social constraints, and human is more a complex creature rather than, over copper wires, a piece of (possibly cleverly falsified) transmitted information.

un vietnamien bien tranquille

aving a time to read some notable documents: The spy who loved us – Thomas Bass, and The perfect spy – Larry Berman. At first, I’d thought: oh, all these stories I’ve knew quite well already, there’s no need to read more. But then I considered it’s good to be reflective, reading the same stories in another language, from other points of view.

I’d read these two books (in English), which contains quite some interpreting errors (most of them are unintentional I think) then I proceeded to their Vietnamese translations (which are really bad, lots of linguistic mistakes), but again another reflections of reflections. All readings confirmed my understanding about the Vietnamese legendary intelligence agent Phạm Xuân Ẩn, whose role is now recognized as crucially decisive in the second IndoChina war.

Espionage and Journalism

As the first IndoChina war was approaching its end, the Việt Minh leaders knew that it’s just a matter of time before the American get their hands in. They had lived and fought with the French long enough that they had extensively well understanding on their enemy, the same is not true for the Americans. During the 9 years of the first IndoChina war, Ẩn had already worked against the French, under his cousin Phạm Xuân Giai, head of South Vietnam’s Cinquième Bureau – department for psychological warfare, who was working for the French’s Deuxième Bureau.

In 1957, Phạm Xuân Ẩn was ordered to go to the States, studying journalism (as a cover), learning their language, culture, their way of thinking… a preparation that later turned out to have devastating effects. During the time in America (and even long before), Ẩn has developed a sympathy (if not admiration) for American people and culture, and at the same time, touting his horns in a war to come against them.

These two professions were very contradictory, but also very similar. The intelligence job involves collecting information, analyzing it, and jealously keeping it secret, like a cat covering its droppings. The journalist, on the other hand, collects information, analyzes it, and then publishes it to the world. (Phạm Xuân Ẩn)

Information and disinformation

Upon coming back (1959), Ẩn worked for several presses: Việt Tấn Xã, Reuters, Time… Among all journalists in Saigon at the time, Ẩn is considered to be the best informants: new – comers introduced with him for guidances, seasoned ones seeked him for tips. He had various sources in the governments, army officers, secret polices… he had the best ears on the ground for everything. He is dubbed: “the weatherman” who foretell the political atmosphere, generals consulted him before planning coup d’état, the Buddhist monks informed him in advance if they prepare a protestant self – burning.

He made very good friend and closed cooperation with Edward Lansdale, head of IndoChina CIA division, the legendary agent nick – named: the king – maker, who manipulated every puppets on the Southern political stage, yet Lansdale had never doubted it. People was thinking he could be a CIA agent, a French sûreté, a South VN secret police, or he could be both. But none ever thought of him working for the Red NLF.

After the war, upon learning about the fact, some of his colleagues have tried to prove that Ẩn could had been giving disinformation at times. In fact, all his written records at the Time magazine (where he worked for 10 years) proved the opposite. Had he done it, with all the overwhelming clandestine agents among the presses, things could have easily been cross – checked and that would betray Ẩn, the espionage. And he of course hadn’t made those preliminary mistakes.

The source had given me the story on condition that I shouldn’t reveal it before it happened. These are the ethics of the press. You have to observe them, no matter how tough it may be. These are also the ethics of an intelligence agent who knows the propaganda value of burning monks. (Phạm Xuân Ẩn)

Balance and Objective

One thing Ẩn learned in American news career is that: a writing must be well – balanced, not biased in any directions, and at the same time it has to be objective, giving useful information to help coming to some helpful conclusions. Yet the two are usually contradictory. Similarly, questions have been raised about the nature of a man who lived an extremely dangerous double life for 30 years, about the one who deeply admires American culture but fiercefully fights against them.

In fact, Ẩn made true friend to many American journalists, help them in many cases, many of whom still love him even after learning that he was a spy. Many would recall how he saved the life of Robert Sam Anson, the war correspondent who was arrested by the VC in Cambodia. Ẩn came closest to getting discovered when he promised to Anson’s wife (who was begging for help) that he would do everything he could, a dangerous remark which implies he really could do something. Anson was later released as per request Ẩn made to his superiors, a truth Anson would only know for sure years later.

He was a man of wisdom, courage, and clear – headed patriotism. He was also – even if it seems ironic to say this under the circumstances – a man of extraordinary integrity. He loved us at our best even while confronting us at our worst. (Daniel Ellsberg)

Strategy and Tactic

A pattern in Ẩn’s stories, as usual, as an amusing raconteur: I’m a strategic analyst, I was concentrating on background information and situation assessment. Yet it’s a reason he gives in order not to get into too much details that he wouldn’t want to release even in the next 50 years: that’s related to too many people, many have died, but some still alive with their relatives, there’s no reason to cause harm to them anyway (Ẩn has always been loyal and protective to his information sources, from either sides, many of which is built upon personal relations).

But Western researchers found this an “undeniable fact”: he’s been awarded with 16 medals, among which 2 are general (one “Hero of the People’s Army” medal, the highest military award in VN, and another medal for “50 years of Party’s service”), the other 14 are all credited to specific battles, 4 of which is apparently known: the Ấp Bắc battle (1963), the Tết offensive (1968), the Lam Sơn 1972 operation, and the final 1975 campaign. That gives some obvious hints on his role as a tactical adviser who devised detailed tactics to be used in various battles.

He would have had enough knowledge of the battlefield tactics, rules of engagement, logistics and battle – readiness of both the Vietnamese and Americans in that area at that time to give pretty good advice on the way to set up a trap for them. Certainly Ấp Bắc had the hallmarks of a trap. (Nick Turner)

Nguyễn Văn Tào (nom de guerre: Tư Cang), head of the H.63 spy ring, direct ‘boss’ of Phạm Xuân Ẩn, famous for his ability of pistol shooting with both hands, and never miss a shot.

Phạm Xuân Ẩn (nom de guerre: Hai Trung), the strategic analyzer whose information, documents, assessments… greatly changed the pace of war.

Nguyễn Văn Thương (nom de guerre: Hai Thương), one of the couriers who run Ẩn’s messages. He was arrested, tortured, both his 2 legs were cut off six times, each without any narcotic. He could had saved his life, but he chose to save the network.

How could someone so voluble and open about his life be a spy? How could someone so funny and pointed in his remarks about human stupidity be a Communist? …He was a divided man of utter integrity, someone who lived a lie and always told the truth. (Thomas Bass)

Communists and Nationalists

This is the point of hatred conflicting among Vietnamese communities for so many years. My point of view, which is also reflected tho – throughly throughout the books (can be seen as 2 American views) is that: the communists, they had an ideologue (no matter right or wrong it could be), and they had determinations. On that basics, they’d had detailed planning and extensive efforts to carry it out, and they’d made sacrifices to carry it out to the end. The same is not true with the so called southerners’ nationalism.

As long as the Americans were pumping money in, the Southern government staffs were trying to steal as much as possible, and pretend to be supportive to the Americans’ causes while avoiding fights and casualties on the battle fields. They’d lost, as they presented nothing, not nationalists, not even anti – communists, but only their own personal and family’s interests. The consequence can be seen clearly: the majority of southern people took side, they have always been sympathetic to the Communists’ national independence causes, although they’re not communists.

Communism and Patriotism

It would eventually become clear why so many people have made extreme efforts and sacrifices, it was not because of any ideology. Of the total 43 members of the H.63 espionage network, 25 were captured, tortured, many of them chose to die, but the network remained unbroken. They were couriers, who in 15 continuous years, ran the total 498 messages (reports) from Phạm Xuân Ẩn to the Iron Triangle Củ Chi, from where it would be delivered directly to the Politburo in Hà Nội. Ẩn always kept an poison pill in his pocket, ready for a death that was hanging over him for those 15 years.

Many who survived the war found themselves disillusioned with the post – war living, finding that the new regime has become even more corrupted than the previous one, and that is not what they were fighting for. Yet they were fighting not for any individual, any ideology, any government… Many failed to realize it is patriotism in the truest and deepest meaning! Phạm Xuân Ẩn to the last year of his life, works as an consultant to TC2 (the Vietnamese equivalence of Deuxième Bureau), who doesn’t understand and doesn’t trust him, but badly need his razor – sharp analyses and assessments.

Lessons learnt

If something can be learnt from Phạm Xuân Ẩn’s life, it’s something about cultural understanding. While most VC has very limited knowledge about American culture and values, they’d succeeded in cultivating at least one spy who could think like an American, a spy who loved Americans and was loved by them in return. That way he can get deep into the adversary’s mind and soul, and know the way to defeat them.

It’s all about understanding, the French had stayed in Vietnam for a considerable amount of time, they’d learnt to divide and conquer the Vietnamese, a job they’d done excellently. It took a few generations to absorb their culture, to gain enough understanding to have successful retaliations. What the American had done in Vietnam to some extent was repeating things the French had done already, in a far larger scale.

Those above are indeed the small part of the lessons. Ẩn said: the American are very good at collecting and analyzing information, but they don’t know what to do with them (at least in scopes of the Vietnam war). Similarly, we can say: the Vietnamese know how to obtain a victory (or it supposes to be called so), but then they don’t know what to do with it. Phạm Xuân Ẩn in person is a talkative one, he can talk about his thinking all day.

But as a spy, a strategic analyzer, he is actually a very quite Vietnamese, who had much more profound thoughts and understanding but can’t say it out. Lots of our own problems are briefly reflected throughout the American books, but they’re not recognized tho – throughly by our own people… Things get passed silently in our sleeping – pleasing minds until another war, another revolution that is… just pending.

basic algorithms

The book is my primary source of interest while being a freshman, which presents a wide range of algorithms in a very coherent and systematic way. I remember “rescuing” this hard-copy from a Fahasa‘s junk pile for about 4 USD, which from that time on became a student’s most precious thing! You can read the soft-copy here.

his is among the subjects I was very fascinated the early years at university: algorithms, graph theory, geometry, image processing… I was not quite good at “symbolic” math (like algebra), but “visual” math offered me much inspiration. The thing I would remember most is Robert Sedgewick‘s Algorithms, a book that I’ve read through over and over again many many times. It is indeed the most important Computer Science textbook that beginners MUST read until today.

The Java applet below is “refurbished” from the code I wrote the first year at college, which visualizes the nature of different sorting algorithms (original code was written in Borland C++ 3.1 with BGI – Borland Graphics Interface). This is among my various attempts to visualize the knowledge collected from the book, which had taught me that even a simple thing like “bubble sort” is not that “very simple”! Let select an algorithm in the dropdown list and click ‘Start’ and see the differences!

My visualizations above are very early (1997), much prior to those demonstrations on wiki. Later on, I’d learned that the author R.Sedgewick put a great emphasis on algorithms’ visualizing himself, his work used PostScript. Many new ways of visualization are really impressive and easy to understand, such as this (using JavaScript).

I started with with C/C++ at school, then continue with C/C++, Java, Design Patterns… on various projects. Later I abandoned Design Patterns (and Java), then I abandoned C++. To me there’s no Design Patterns, there’s only data structures and algorithms! Would write another post on the bloating and non-sense usages of Design Patterns later on!

It seems that most software engineers today lack fundamental knowledges and skills. It’s quite apparent that you could not rely on a guy talking about architecture, GoF’s design patterns… all the time but can not state the algorithmic differences between a DFS (depth first search) and a BFS (breadth first search).

diệc lạc hồ

双鸟齐飞

黄莺飞到北京都
会遇金鹏亦乐乎
大事未成行小事
双鸟齐飞至善图

Song điểu tề phi

Hoàng Oanh phi đáo Bắc Kinh đô, Hội ngộ Kim Bằng diệc lạc hồ! Đại sự vị thành, hành tiểu sự, Song điểu tề phi chí thiện đồ!

hân kỷ niệm 60 năm quốc khánh nước CHND Trung Hoa (1/10/1949 ~ 1/10/2009), trích đăng lại ở đây bài thơ của một nhân viên ngoại giao đoàn Việt Nam (đăng trên Tạp chí Sông Hương, 2002): Bài thơ thể hiện tình hữu nghị cao quý của nhân dân hai nước Việt – Trung. Bài thơ được làm năm 1991, sau một thời gian dài 10 năm (kể từ 1981), khi hai nước tuy không còn những đối đầu quân sự lớn, nhưng hai bên vẫn tiến hành một đường lối tạm gọi là artillery diplomaticngoại giao pháo binh – chân lý, lẽ phải đứng trên đầu nòng đại bác.

Các địa danh đẫm máu như Vị Xuyên, Ngọc Đường, Lũng Cú… những người từng bám trụ 10 năm ở đó đến nay vẫn nhiều người còn sống, vẫn còn kể lại chuyện ngày xưa ở đâu đó quanh đây. Trở lại với bài thơ, năm 1991, một đoàn ngoại giao VN sang TQ, những bước đi đầu tiên của tiến trình bình thường hóa quan hệ. Trưởng đoàn phía VN là ông Vũ Oanh, trưởng đoàn phía TQ là ông Lý Bằng.

Cả “Oanh” và “Bằng” đều là tên của hai loài chim (không giống nhau), như được thể hiện rất rõ trong bài thơ trên đây: Song điểu tề phiĐôi chim cùng bay. Không cần phải biết chữ Hoa, đọc phiên âm Hán Việt hẳn mọi người cũng sẽ dễ dàng hiểu nội dung bài thơ! Chúng ta thấy lại cái điệp khúc Diệc lạc hồ ở đây! Diệc lạc hồ (hay Bất diệc lạc hồ) đều có thể hiểu theo nhiều kiểu: vui lắm thay, há không vui hay sao… hay theo phương ngữ miền Nam: vui quá hén! 😬

fooled by randomness

sually on my birthday, I would receive messages like: Congratulation to the Party! Congratulation to the government! Congratulation to President Ho Chi Minh! (the day happens to be also the Man’s birthday) 😬. But last month, I received this book, a nice gift from a friend, a soft – paperback hard – copy of the famous writing: Fooled by Randomness! I’m now half – way through the book, a bit difficult for non – English – native readers, but really interesting in every details!

My major hobby is teasing people who take themselves & the quality of their knowledge too seriously & those who don’t have the courage to sometimes say: I don’t know. You may not be able to change the world but… (www . fooled by randomness . com)

As with every outstanding thinkers and thinkings, the book’s caused controversies since it was first published (2001), written by Nassim Nicholas Taleb, a skeptical scholar and at the same time, a successful trader. I’ve been for long, looking forward to these types of cognitive thoughts! It’s too soon to have some comments on the book, but for now, the debate between Einstein and Heisenberg, between determinism and un – determinism would just go on!

the sorrow of war… film?

“Better to die than surrender, my brothers! Better to die!” – the battalion commander yelled insanely; waving his pistol, and in front of Kien, he blew his own brains out through his ear. (The Sorrow of War)

An un-put-down-able novel. It should win the Pulitzer prize, but it won’t. It’s too gripping for that. (The Guardian)

Dramatic… Will force American readers to acknowledge how little they still understand of the long war that left such a legacy of grief and guilt in their own country. (The Washington Post)

The Sorrow of War has won worldwide acclaim and become an international best-seller. (Amazon.com)

good news: 8th, May, 2008, The Sorrow of War novel will be turned into movie by an American director: Nicolas Simon. After 10 years of discussion and negotiation, Bảo Ninh, the novel’s author finally permitted making of the film based on his famous book. The producer, Dominic Scriven, a very passionate admirer and friend of the author, who now holds the book copyright and want to transfer it onto the silver screen. An even better news: 9th, Aug, 2008, author of The Sorrow of War novel stated that he wouldn’t have any further connection with the The Sorrow of War movie project.

The reason given is: film’s script is not aligned with the author’s ideas. In fact, many people is doubtful that an unnamed director would be capable of working on such a great novel, although the producer (Dominic Scriven) ‘s goodwill is widely recognized! The movie project is now paused, in searching for another director! That’s a very good thing in my opinion, in the fear that we would have another history distortion (or even worse)! A picture is worth a thousand words? That’s not always true, think twice (or read the book)! In this case, words are worth thousands of pictures (or a movie)!

The novel is, more or less, an semi – autobiography. Bảo Ninh himself (or the protagonist Kiên in the novel) was a soldier in the 24th battalion, a special formation commissioned to the B3 front (central highland) in 1969. Of the unit’s 500 man, he is among the only 10 survivors. The story is an nonlinear scatter of memories, mixed the past with the moments of post-war time: childhood, a high school’s love story, the battles, and importantly lives after war.

The Sorrow of War is without doubt timeless. Perhaps it is one of the world’s greatest war novels ever written. Imagine the film Apocalypse Now and increase its effect, say by a factor of a thousand – this is the power of Bảo Ninh’s writing. I remember shivers in my spine when first reading the book, some 15 years ago! Just surf around some online bookstores, to see what readers have said about the book:

  • If this book doesn’t make you cry, you have no soul.

  • It’s definitely not a book for everyone, and I nearly put it down during the first 50-60 pages. But, I soon became wrapped up in the story and the language.

  • Books usually lay with me on my bed and after their formal end we sleep together for a few days but after the last sentence I promptly put this right back on my shelf and am having trouble thinking about it again. I had horrible nightmares during the read.

  • This book is amazing. The story progresses thematically rather than chronologically, and leaves you piecing together historical non-fictional events… He succeeds in taking the reader on a difficult journey of emotional and spiritual crisis, right to the core of the human condition and captures a sorrowful despair like no other literature I’ve ever read.

  • Like pouring acid on your moral center…

  • Just an excellent novel. To everybody who considers The Things They Carried the penultimate work of fiction about the Vietnam War: pick up The Sorrow of War and be prepared to be blown away by the stories of a Vietnamese.

  • In fact, my view of just about everything I thought I knew about North Vietnam from the mid-60’s to the mid-70’s was altered by this book.

  • This book is unbelievably emotional. The style of writing is unique: it is not linear or chronological in any way. It is chaotic, a reflection on the subject of the book. The writing style, though chaotic, seems to be a perfected style. The book was written with total disregard to order; there is no doubt that all was deliberate.
