Update!!! Apple's new iPhone 2008

I almost bought an iPhone (sold around $500 USD) in 2007. Glad that I didn't do it. Now the new iPhone costs only $199. Though Steve Jobs is credited with the coming back of Apple, some of his decisions really turn consumers off. Remember, in the early 80's, he didn't like the Macintosh and was kicked out from Apple. Later Macintosh became the hot, dominated product in the 80's. Jobs was also opposed to making Macintosh an open platform. Otherwise, MacOS, not Windows, would have become the most popular operating system now. The decline of Apple in the 90's was a classic show case of how propriety products lost to open standard (Windows) products.

I love my iPod. However, with iPod, you can only download songs from Apple's site. Chances are there will be sites offer more songs, better choices to customers of the world. Apple will not sustain its current victory with the mentality of Apple vs the rest of the world. There are already a lot cheaper, even better imitation of iPods. Will iPhone, iPod be cool forever?

Update:
iPhone 3G phne: $199 USD
iTouch (basically, an iPhone without a 3G phone): $299 USD

New!!! Powerset 、Google 莊子論

(Related Articles: Goo韓邵逸夫)
宣稱要以 Google 為假想敵的 Powerset.com 搜尋器, 自然要留要意一下, 暫時未見 Powerset 有何特出之處。Google 及 Yahoo 是用關鍵字(Keyword)去搜尋文章,Powerset 則要用者(User)輸入Natural Language, 即書寫及交談用的語言。用者輸入整個句子給 Powerset, 會否比 Google 找出更好的效果? 用者搜尋器找資料, 步驟如下:
1. 心中構思要找尋的東西(意)
2. 想出與該有關的關鍵字
4. 輸入搜尋器
6. 搜尋器輸出有關文章

Powerset 需要在以上步驟按次序加多兩步:
3. 用關鍵字構成完整句子(言)
5. 搜尋器將完整句子分解成關鍵字

難處在於, 意及言很多時都不是一一對應, 同一個意思, 可用不同文句來表達; 同一個文句, 亦可令不同讀者產生不同意思。所以, 用者想要找某些資料, 輸入整個句子並不一定是最好的方法。這令我想起了莊子"得意忘言"那句話:
筌 者 所 以 在 魚 , 得 魚 而 忘 筌 ﹔ 蹄 者 所 以 在 兔 , 得 兔 而 忘 蹄 ﹔ 言 者 所 以 在 意 , 得 意 而 忘 言 。 吾 安 得 夫 忘 言 之 人 而 與 之 言 哉 ! 」《莊子·外物》

莊子認為, 語言文字只是傳達意思的工具, 得到魚兔之後, 捕捉魚兔的工具筌蹄便可以不要, 所以意比言重要。要傳達"意", 用關鍵字會更快更準, 將來在Web ?.0 時代, 連圖畫、聲音都可以輸入, 又何必拘泥於整個句子文字? 忘言吧。

要賺錢, Powerset 的目的可能是要上市或等大公司收購, Microsoft 的 Bill Gates 一向對這類技術有興趣, 當然還有Google。

奪寶奇兵與占士邦: 歐美價值觀的分歧

Q: 奪寶奇兵的 Indiana Jones 與占士邦 (James Bond) 有何差異對比?

兩套片集的分別, 在於個人與組織。在占士邦片裏面, 壞蛋絕大部份是個人--富翁, 正義的一方是政府 (組織), 記著, 占士邦背後還有一大班人幫他發展新武器。奪寶奇兵正好相反, 壞蛋都是組織, 如國社黨 (納粹) 政府、蘇聯政府及邪教, 正義的一方是個個人英雄, 不需靠政府幫助。

要從美國革命說起, 革命目的, 除了要炒英皇魷魚之外, 更有新的哲學思維。形響美國革命至深的 Common Sense 一書, 提出政府及社會的分別, 對政府抱懷疑及不信任的態度, 崇尚個人主義。Common Sense 又質疑單憑血統而得到統治權的歐洲貴族, 使美國人不尚血統而崇尚講究能力的 Meritocracy。

奪寶奇兵電影裏面, 邪惡的都是一些外國政府。片裏的美國政府, 頂多是不誤主角的事, 幫不了忙。主角千辛萬苦取得了的約櫃, 美國政府只會束之高閣, 盡顯官僚本性。

西歐人比較相信政府, 認為政府可促進社會公義。富翁會被視為貪婪的象徵, 因此西歐社會多高稅高福利。西歐對富翁的輕視, 正好反映在占士邦小說及電影裏面。

Society in every state is a blessing, but government even in its best state is but a necessary evil; in its worst state an intolerable one -- Common Sense (1776)

A touching earthquake story

If you don't read Chinese characters, fine. Just look at the picture.

http://www.worldjournal.com/wj-ch-news.php?nt_seq_id=1717429&sc_seq_id=3

In Beichuan, Sichuan, China, rescuers found a dead mother kneeling on her legs, her body leaning forward and forearms touching the ground. Underneath her body rescuers found her infant daughter. The mother's protective posture successfully saved the baby.

The rescuers also found a cellphone nearby with this text message:
Dear baby, if you ever live, remember that I love you.

In memory of the earthquake victims

My heart sank about when heard about the news that thousands of people were buried alive. Don't know what to say. Just wish as many people can be saved as possible.

Can animals predict earthquake?

A sad day for China and the world. Hope those being trapped will be rescued soon.

It is said that the U.S. first reported the earthquake in Sichuan, China. Though the U.S. may have the best earthquake data collection in the world, they may not have the best use of earthquake data. Like many other earthquakes, there were many abnormal animal behaviors prior to the Sichuan event. Naturally, researchers tried to find out whether animal could assist earthquakes prediction. The American strongly denied animal's abilities and focused only on geological earthquake prediction. The best they can do is to predict that a certain probability, says, 40% probability of earthquake will happen in a given area and a given period.

Prob_USA_Method = f (G)

Asian countries employed various animal prediction techniques but lacked the sophisticated U.S. geological data collection technologies.

Prob_Asia_Method = f (g + A) where A is animal factor. A small g is given because it is not as good.

Of course, the question is, if factor A is really a good factor. If A is good for earthquake prediction and if Asian countries have full access on the U.S. data, the probability may rises significantly, says, from 40% to 75%.

Prob = f (G + A)

That will save a lot of lives in the future.

悲情天水圍, 一切盡人為

有關天水圍的的多宗跳樓悲劇, 要由美國的 Suburb 說起。二戰之後, 汽車在美國普及, 在城市工作的中產階級, 開始移居至市郊 (Suburb), 美國市郊化(Suburbanization)的先後原因, 是:
有工中產,有車, 搬到 Suburb (1)

香港最早的美式 Suburb, 應該是錦繡花園及康樂園。偏遠的大型私人屋邨(如天水圍的嘉湖山莊),居民主要靠公共交通出入, 這類屋邨可視之為無車 Suburb, "住大D但遠D, 但交通費貴D"。移居偏遠私人屋邨的先後原因, 是:
有工中產, 搬到無Suburb(2)

港府在天水圍私人屋邨旁大起公屋,又令新移民搬入, 參看粗體字的(1)及(2), 便可知到出了甚麼問題。無工加上昂貴的交通費, 做成坐困愁城的跳樓悲劇。如果我是新移民, 我會留在市區。要住優質 Suburb, 請先打好基礎, 香港有的是機會。將新移民搬到偏遠的 Suburb, 不能造成中產; 正如我們不會因為先搬到山頂而變成富豪一樣。
