unity




Screenshots of the new Unity desktop. There’s certainly a harsh non – exclusive competing between Unity and GNOME Shell. A proxy war between Ubuntu and Fedora Core, which is in turn a proxy war between Canonical and Red Hat.
Eventually, it’s user experiences that would decide which desktop is best (and best for what), and that’s still a long way to come. But technically, Unity is the first huge bold break from tradition, whose real goal deep inside is replacing completely the age – old heritage of X window system by an OpenGL – based one, a problem partially addressed in my previous post.

am trying Ubuntu’s new desktop introduced lately with Natty Narwhal (11.04). After heavy development phases, Unity has reached its alpha stage, a massive move replacing the GNOME desktop environment by a completely new one written from scratch. I’ve read too many negative reviews about Unity already, but personally I think this is a good move. Developed from Ubuntu’s Netbook Remix (which I didn’t like much, you don’t have to maximize windows like that all the time), switched from Clutter to Compiz 3D windows compositing system (my last experiment with Clutter also hinted potential performance problems), the new Unity shows a huge shift toward Mac’s style desktop. Though there’s still lots of bugs and missing features, a few things can be said about this new Unity.

First, people complains about the break from the norms, some hates Unity because it stops their accustomed habits. The GNOME community (with its long development history) can feel like being betrayed. But for all I knew after some years in graphics, UI design is the job of personality, it’s the task of a small group who decides what is “nice and beautiful”, and which is the way (for other users) to follow, it’s not the task of a committee (that is “People’s Committee” I mean 😀 ). As a developer, I’m often in the self – conflicting state of wondering what is “nice and beautiful”, modify over and over again some simple UI widgets. It’s no strange that UI always becomes a huge diversity (and problems) for community – driven projects. Key requirements for a UI system in my opinion are: simplicity, consistency and elegance.

For consistency and simplicity, Unity is a big step forward, reasons given that GNOME has become too complex and inconsistent (then how about the much more complex KDE?). Maximized windows have the caption and menu bars all incorporated into the system bar on top, a feature clearly borrowed from Mac, yet further varied and developed. A simple dock bar is positioned on the left, and system menu button doesn’t bring up menu but a searching panel with which you can launch programs, open files… with a few key strokes. I like this much cause it offers a form of GNOME – Do: it’s harder to launch rarely – used items (especially if you don’t remember the names) but it’s more convenient for frequently – used ones. After all, lexical memory is much faster than spatial memory, if one has been trained to that.

One more apparent physical factor is that the vertical screen space is more scarce compared to horizontal space, and 16:9 screens has become quite popular. To conserve useful screen space, UI must make constraints to the caption, menu bars, especially tool bars, there’s even recommendations on eliminating the status bar and minimizing scroll bar at Mark Shuttleworth’s (Canonical’s founder) blog. For scroll bar, that’s quite sure a mimic and modified version taken from iOS. Actually with my recent experiences with Mac and iOS, there’s still a lot of lessons to be learned from these two OSes on how to use space efficiently: remove heavy windows decorations and borders, use lighter UI fonts, smaller and more symbolic icons, design simpler widgets… and in cases even sacrifice some less – used UI features.

The trend of UI becoming simpler and more consistent is quite obvious. Efficient uses of space is the key, but spatial is not all for user experiences: keyboard and mnemonic are also important parts of the learning path (UI effects can be fancy, but over time, people get to love the simplest keystrokes that do the job). The third factor: elegance is even more a topic of debate, people can largely agree to what is simplicity and consistency, but what is aesthetics remains mysterious! Unity claims that it would directly compete Mac on UI designs and user experiences, but my opinion is that its aesthetic aspect is still far behind that of Mac, e.g: Compiz’s effects are numerous, but actually not very fine – tuned compared to the smaller set of animations Mac offers… And even Mac still doesn’t satisfy my eyes in quite many cases…

the tự – do boat



The boat now belongs to the Australian National Maritime Museum. It has been refurbished and restored to the original design with the help of the Lu family, and preserved as a museum’s fully – operational object to demonstrate the country’s immigration history, the whole story is recited here.

nteresting story about a Vietnamese boat – people‘s vessel, the one dubbed: Tự do – Freedom. In 1976, the boat was laid down at Phú Quốc island as a dragnet fishing vessel, a construction built just for the escape from the newly – formed regime (1975). Mr. Tan Than Lu planned his escape meticulously along with his family, relatives and friends.

The hull (as seen in the images) still incorporates in it some Vietnamese indigenous ship building features, the registration number reads: VNKG1062, which indicates that the boat originally had its home port in Kiên Giang, Việt Nam. Hull dimensions: 19.4m (length), 5.2m (beam) and 1.8m (draft). It must be noticed that the Lu family is a very rare case among almost half a million of Vietnamese boat – people at the time, very few could afford building such a boat for escaping, and few had had such a lucky and successful trip.

The boat involved in fishing for half a year to allay government’s suspicion. Then pretended to have an engine breakdown so that surveillance of them would be relaxed, a more powerful replacement engine was installed during the night, children were given cough medicine to make them sleep and keep silence, the crew of 38 departed on Aug 16th, 1977. They arrived at Mersing, Malaysia, where 8 passengers were disembarked as refugees.

After one month of unsuccessful approaches to the US Embassy, Mr. Lu decided to set sail for Australia with the remaining 30 people on board. They were resupplied and encouraged to move on by the Indonesian authorities. They reached Darwin, Australia on Nov 21st, 1977 after a 6000 kilometers journey guided only by map torn from a schoolbook and a simple compass.

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.
