“美版犀利哥”傳奇︰播音員變流浪漢再變名人


美國“犀利哥”泰德︰“我有上帝恩賜的完美聲音。”

  泰德•威廉姆斯是誰?一星期之前,這個名叫泰德•威廉姆斯的美國黑人還是俄亥俄州哥倫布市街頭的流浪漢,已經53歲的他因為吸毒和酗酒,失去了工作,住在一頂又髒又破的帳篷里,過著饑一頓飽一頓的生活。

  命運的轉折發生在不經意間。這天,哥倫布市郵報的一名記者駕車經過街頭,發現了這個流浪漢身上與眾不同的地方︰聲音。他有一副天鵝絨般的嗓子,渾厚而富有磁性,標準播音員的嗓音配上流浪漢窮困潦倒的外形,讓記者大為稱奇。沒有猶豫,記者記錄下這雷人的一幕,隨即將視頻傳到了網上。

  從2011年第一個星期一開始,美國“犀利哥”泰德變成了Youtube上大紅大紫的明星,他那頹廢而瀟灑的扮相,離奇而真實的身世和富有磁性的嗓音吸引了千百萬網民的眼球,短短時間內已經有超過700萬的瀏覽量。NBC、MSNBC、CBS等各種媒體的采訪更是接二連三,讓泰德一舉成名。

  不少商業機構瞅準商機,紛紛向泰德發出邀請,卡夫食品請他為通心粉和奶酪做廣告,克里夫蘭騎士隊邀他出任現場解說,多少人夢寐以求的職位都擺在了這個曾經的流浪漢面前,一度讓他頭暈目眩。

  然而讓人感動的故事還在後面,泰德92歲的老母親現住在紐約,母子倆已經幾十年沒有相見,泰德的成名終于帶來了母子團圓的機會,在攝像機、照相機的簇擁下,泰德和母親緊緊擁抱在一起,母子倆喜極而泣。泰德說,自己曾經祈禱,要讓母親親眼看到自己的生活好轉起來,沒想到這一切夢想成真。

  泰德的身世頗有傳奇色彩。出生在紐約的他從小對播音充滿濃厚的興趣,參加過專門的播音訓練,後來成功的成為一家電台的播音員,還是7個孩子的父親。後來因為濫用毒品和酗酒,他失去了體面的工作和幸福的家庭,唯一的一頂帳篷成了他的“家”。一份檔案披露了20多年來泰德的“光輝歷史”,他曾多次被監禁,罪名也五花八樣︰偽造罪,持有毒品罪,盜竊,搶劫,逃跑,不一而足。對此泰德也坦率承認,不過他說,那都是過去的錯,現在他有了重新做人的機會,他絕不會再錯過。

  泰德的故事已經具備了一部主流的好萊塢影片的全部要素︰從誤入歧途,濫用藥品到洗心革面,浪子回頭,充滿迂回曲折,也不乏積極向上。有好事者已經開始預測,誰將在這部好萊塢大片中擔當男主角,就讓我們拭目以待吧。

IBM's Watson Computer Wallops 'Jeopardy!' Champs in Trial Run

Published January 13, 2011 FoxNews.com



Our robot overlord isn’t named HAL or SkyNET -- it’s Watson.

After four years of development, IBM on Thursday publicly unveiled a computing system that specializes in analyzing natural human language and answering complex questions. In other words, it’s really good at Jeopardy!.

To test its acumen, the machine was pitted in an exhibition match against the most celebrated human contestants, Ken Jennings and Brad Rutter, to stunning effect. Watson quickly cleared out the entire first category without the humans getting even a buzz in.

Named after IBM founder Thomas J. Watson, the project is a defining breakthrough in artificial intelligence technology, said John E. Kelly III, senior vice president and director of IBM Research.

“We’ve created a system that can interact in a very special way,” he said at the demonstration. “People spend their lifetime trying to advance [the field of artificial intelligence] by inches. What Watson does has demonstrated the ability to advance the field of artificial intelligence by miles.”

Today’s practice run was just a glimpse of what's to come, in other words. IBM announced the contest in December. The official first-ever man vs. machine Jeopardy competition will take place Friday, and will air on February 14, 15, and 16.

It’s not the first time IBM has used its technological know-how to pit people against computers. The announcement of Watson brings back memories of Deep Blue, the supercomputer that, after a few initial setbacks, went on to defeat world chess champ Gary Kasparov. The similarities end there.

Chess is a game tailor-made for the logical ones and zeros of artificial intelligence, with its perfect parameters and finite though tremendously large number of possible outcomes. Jeopardy! is a wholly different beast because of the human factor -- and as such, there is inherent uncertainty.

“When we deal with language, things are very different,” said David Ferrucci, principal investigator of Watson's DeepQA technology at IBM Research. “Language is ambiguous, it’s contextual, its implicit. Words are grounded really only in human cognition -- and there’s seemingly an infinite number of ways the same meaning can be expressed in language. It’s an incredibly difficult problem for computers.”

Coding that “human-ness” has been the primary work of 25 of IBM’s top research scientists and they’ve accomplished it with a mish-mash of algorithms and raw computing technology. Watson is powered by 10 racks of IBM Power 750 servers with 2,880 processor cores and 15 terabytes of RAM; it's capable of operating at a galloping 80 teraflops.

With that sort of computing power, Watson is able to quickly analyze natural human language, scour its roughly 200 million pages of stored content -- about 1 million books worth -- and find an answer with confidence in as little as 3 seconds.

“What Jeopardy! does for us is it gave us this compelling and notable way to drive and measure that technology along the key dimensions,” Ferrucci said.

It is that human factor that makes Watson so innovative yet in a way also somewhat unsettling, perfectly echoed by the vignette of an empty space between the two contestants on stage. At one point, upon finishing the last question in the category “Girls Dig Me,” Watson even made a joke -- causing the audience to erupt in laughter and applause.

It seems IBM's machine was not only smart, it was funny.

With this milestone passed, fears of a machine-led takeover seem premature, but the topic was certainly on the minds of contestants. Jennings put it best, saying he was probably less John Henry and more John Connor.

“[HAL 9000] is science fiction,” Ferucci admitted. “I don’t think we’re anywhere near that or going in that direction. One inspiration for this kind of technology from science fiction, at least for me, is the computer on Star Trek. They built a system that helps you with your information needs, understands your question, organizes it, and presents it in a way that you can digest it quickly.”

Though Watson ended the exhibition in the lead with $4,400 compared to Jenning’s $3,400 and Rutter’s $1,200, a continuation of that battle shown on internal televisions during lunch revealed that Jenning had pulled ahead after scoring a Daily Double. Watson still isn’t perfect, it seems.

While she wouldn’t reveal specific numbers, one IBMer revealed that Watson has lost during recent practice runs to lesser opponents. Ken Jennings, of course, is on a completely different level. The computer programmer shot to public prominence when he won a record 74 consecutive games, netting him more than $2.5 million in winnings.

And while Watson operates operates on calculated confidence, buzzing in if it knows to a certain degree the right answer, people -- Jennings in particular -- use intuition, often buzzing in before they even know the answer simply because they feel like they know it, giving him a concrete speed advantage.

Watson is constantly improving, of course. Kelly estimates an increase of 50% every 20 months it spends learning. Ferrucci was quick to remind the audience who was in charge.

After all, it was humans who built Watson in the first place.

Segmented Economic Recovery, Asset Value Inflation; Sluggish Job Growth

Equity stock market begins with a good start for the year. Market is consolidating at current level for the sizable gain in the last quarter. Trading volume increases as investors return from holiday.

It is officially announced that the recession has ended in last year. Those investors waiting for the double dip has already returned to the market in October last year providing strong support for the market. Commodities also see a significant gain since investors are chasing after various kind of assets with the exception of real estate. The latter was once very popular among household investors who switched to the money and bond market after the financial crisis but recently turned to the equity stock market.

Economy is back to normal as people are back to normal life after the shock. However the job market does not recover because corporations use the opportunity for downsizing to improve efficiency as well as profitability. Although consumer demand for goods and services rises back to previous level, the demand for labour force does not rise accordingly due to various factors such as office and factory automation, off-shore outsourcing, etc. This creates a structural loophole in the job market. The financial crisis serves as a trigger to hasten the change and it is a path of no return.

It is the objective of Federal Reserve to implement "Quantitative Easing" to hold up asset value so that the wealth effect will encourage consumers to spend to support the economy. It works as planned except that job growth is disproportional to economic activity growth. This problem may not be adequately solved by fiscal measures but rather government policy.

"It's a Terrible Recovery": Dan Greenhaus Explains Why The Economy Feels So Bad One more factoid from Greenhaus' report that helps explain why most Americans don't "feel" like we're in a recovery (much less an expansion): The top 20% of U.S. earners account for about 40% of all consumer spending and own about 85% of the U.S. equity market.

Investing Dying as Computer Trading, ETFs & Dark Pools Proliferate "The capital raising stock market of the past hundred years has morphed in just the last 10 years into a casino," said Sal Arnuk of Themis Trading and a market infrastructure expert who advised the SEC after last year's so-called Flash Crash. "Who is doing the fundamental work analyzing stocks? In the end, we've greatly increased systemic risk."

How to beat the market? Only stay a day at a time It's one of the truisms of financial planning: trying to perfectly time the market is a fool's errand. For long-term gains, the advice goes, you should buy index funds and hold them indefinitely. It helped that the stock market hasn't been kind to most investors over the past 11 years.

Factory outlook bright after 17 months of growth Manufacturing activity has expanded in every month since the recession ended a year and a half ago. The big difference now is that the growth is being driven by higher sales and more confident consumers-- not just businesses rebuilding the stockpiles that they slashed during the recession. "You're in a situation where a virtuous cycle is beginning to materialize," said Eric Green, chief economist at TD Securities.

The Rally Isn't Over But Most of the Money Has Been Made, Says Greenhaus History suggests most of the gains made after a bear market bottom come quickly, he says, meaning those who missed the big rally from the March 2009 lows have missed the bulk of the move. "There's a pretty clear relationship between getting in early and achieving most of the gains," Greenhaus tells Aaron in this interview. "You can still achieve gains... but the rate at which those gains accumulate and compound pales in comparison to the initial spike."


As market is consolidating, buy and hold strategy may not be most effective. Short term market outlook is optimistic because market participants have rising risk appetite as a result of flooding capital liquidity and greed from wealth effect. However investors do not have strong confidence in the market rally and impatient for profit taking. Therefore there is sometimes wild oscillation in market movement. Hedge funds are finding opportunities by exploiting the herding behaviour of individual investors who finally returned to the equity stock market after the financial crisis.

There are opportunities in the equity stock market as participants are returning will optimisim. The speculative trading portfolio will follow closely the market cycle and trades will be executed on speculation of market participants activities.

World Bank issues its 1st yuan bonds in Hong Kong

World Bank latest to issue yuan bond as China promotes currency for international use (Kelvin Chan, AP Business Writer, On Wednesday January 5, 2011, 9:15 am EST)

HONG KONG (AP) -- The World Bank is issuing its first bonds denominated in China's yuan in Hong Kong, joining a growing number of borrowers tapping the new debt market as Beijing gradually promotes its tightly controlled currency abroad.

The World Bank said buyers of its 500 million yuan ($76 million), two-year bond were mainly Hong Kong-based financial institutions, companies and wealthy individuals. It said the money will go into its general fund, rather than being raised for a specific purpose.

The yuan is not traded on global currency markets but Beijing has loosened controls and allows Hong Kong banks to use it. Hong Kong is Chinese territory but has its own currency and a Western-style legal system and often is used as a site for mainland companies to interact with foreign investors.

Beijing began allowing foreign companies to issue yuan debt last year. The Asian Development Bank, Caterpillar Inc. and McDonald's Corp. have sold yuan-denominated debt to finance activities in China.

Buyers of such bonds hope to gain from both interest payments and the growing strength of the yuan, which is rising against the U.S. dollar.

China is set to gain a bigger say in the World Bank after a restructuring last year to boost the voting power of developing countries. If approved, China will be the third-biggest voting power after the United States and Japan. The World Bank provides low-interest loans and technical assistance to developing countries.

Beijing is promoting Hong Kong as a platform for yuan-based international banking. Hong Kong banks started handling yuan in 2004 and now offer services ranging from deposits to credit cards to trade financing that allows foreign companies to pay Chinese business partners in yuan.

Analysts say Beijing wants to see the yuan, also known as the renminbi, or people's money, become a global currency like the dollar or euro, though that could take years or decades.

Increased use of the yuan abroad could help China by reducing the exchange-rate risks faced by its exporters, who now are paid mostly in dollars.

"There are so many benefits that China can achieve from shifting trade to the local currency," said Credit Agricole economist Darius Kowalczyk.

Borrowing costs for China's government and companies also would decline if foreign investors were willing to buy more yuan-denominated bonds.

In August, McDonald's Corp. sold nearly $30 million in yuan bonds to pay to build new restaurants in China. Caterpillar sold $150 million in yuan bonds to provide financing for buyers of its heavy equipment.

Also last year, the Asian Development Bank sold $181 million in bonds to raise money to provide development projects in China.
