一個年輕漂亮的美國女孩在美國一家大型網上論壇金融版上發表了這樣一個問題帖︰我怎樣才能嫁給有錢人？
"我下面要說的都是心裡話。本人25歲，非常漂亮，是那種讓人驚艷的漂亮，談吐文雅，有品位，想嫁給年薪50萬美元的人。你也許會說我貪心，但在紐約年薪100萬才算是中產，本人的要求其實不高。
這個版上有沒有年薪超過50萬的人？你們都結婚了嗎？我想請教各位一個問題——怎樣才能嫁給你們這樣的有錢人？我約會過的人中，最有錢的年薪25 萬，這似乎是我的上限。要住進紐約中心公園以西的高尚住宅區，年薪25萬遠遠不夠。我是來誠心誠意請教的。有幾個具體的問題︰一、有錢的單身漢一般都在哪 里消磨時光？ (請列出酒吧、飯店、健身房的名字和詳細地址。)二、我應該把目標定在哪個年齡段？三、為什麼有些富豪的妻子看起來相貌平平？我見過有些女 孩，長相如同白開水，毫無吸引人的地方，但她們卻能嫁入豪門。而單身酒吧里那些迷死人的美女卻運氣不佳。四、你們怎麼決定誰能做妻子，誰只能做女朋友？ (我現在的目標是結婚。)"——波爾斯女士
下面是一個華爾街金融家的回帖︰
"親愛的波爾斯︰我懷著極大的興趣看完了貴帖，相信不少女士也有跟你類似的疑問。讓我以一個投資專家的身份，對你的處境做一分析。我年薪超過50萬，符合你的擇偶標準，所以請相信我並不是在浪費大家的時間。
從生意人的角度來看，跟你結婚是個糟糕的經營決策，道理再明白不過，請聽我解釋。拋開細枝末節，你所說的其實是一筆簡單的"財""貌"交易︰甲方提供述 人的外表，乙方出錢，公平交易，童叟無欺。但是，這里有個致命的問題，你的美貌會消逝，但我的錢卻不會無緣無故減少。事實上，我的收入很可能會逐年遞增． 而你不可能一年比一年漂亮。
因此，從經濟學的角度講，我是增值資產，你是貶值資產，不但貶值，而且是加速貶值! 你現在25，在未來的五年裡，你仍可以保持窈窕的身段，俏麗的容貌，雖然每年略有退步。但美貌消逝的速度會越來越快，如果它是你僅有的資產，十年以後你的價值甚憂。
用華爾街術語說，每筆交易都有一個倉位，跟你交往屬于"交易倉位"(trading position)， 一旦價值下跌就要立即拋售，而不宜長期持有——也就是你想要的婚姻。聽起來很殘忍，但對一件會加速貶值的物資，明智的選擇是租賃，而不是購入。年薪能超過 50萬的人，當然都不是傻瓜，因此我們只會跟你交往，但不會跟你結婚。所以我勸你不要苦苦尋找嫁給有錢人的秘方。
順便說一句，你倒可以想辦法把自己變成年薪50萬的人，這比踫到一個有錢的傻瓜的勝算要大。
希望我的回帖能對你有幫助。如果你對"租賃"感興趣，請跟我聯系。"——羅波．坎貝爾（J•P•摩根銀行多種產業投資顧問）

你今天UGC了嗎? Principles of user generated content services
Principles of user generated content services
http://www.ugcprinciples.com/
1. UGC Services should include in relevant and conspicuous places on their services information that promotes respect for intellectual property rights and discourages users from uploading infringing content.
2. During the upload process, UGC Services should prominently inform users that they may not upload infringing content and that, by uploading content, they affirm that such uploading complies with the UGC Service’s terms of use. The terms of use for UGC Services should prohibit infringing uploads.
3. UGC Services should use effective content identification technology (“Identification Technology”) with the goal of eliminating from their services all infringing user-uploaded audio and video content for which Copyright Owners have provided Reference Material (as described below). To that end and to the extent they have not already done so, by the end of 2007, UGC Services should fully implement commercially reasonable Identification Technology that is highly effective, in relation to other technologies commercially available at the time of implementation, in achieving the goal of eliminating infringing content. UGC Services should enhance or update the Identification Technology as commercially reasonable technology that makes a meaningful difference in achieving the goal becomes available.
a. If a Copyright Owner has provided: (1) the reference data for content required to establish a match with user-uploaded content, (2) instructions regarding how matches should be treated, and (3) representations made in good faith that it possesses the appropriate rights regarding the content (collectively, “Reference Material”), then the UGC Service should apply the Identification Technology to that content to implement the Filtering Process described below. UGC Services should ensure that reasonable specifications, as well as any tools and/or technical support, for the delivery of Reference Material are made available to Copyright Owners. If a Copyright Owner does not include in the Reference Material instructions regarding how matches should be treated, the UGC Service should block content that matches the reference data.
b. The Identification Technology should use Reference Material to identify user-uploaded audio and video content that matches the reference data and should permit Copyright Owners to indicate how matches should be treated.
c. If the Copyright Owner indicates in the applicable Reference Material that it wishes to block user-uploaded content that matches the reference data, the UGC Service should use the Identification Technology to block such matching content before that content would otherwise be made available on its service (“Filtering Process”). The Copyright Owner may indicate in the applicable Reference Material that it wishes to exercise an alternative to blocking (such as allowing the content to be uploaded, licensing use of the content or other options), in which case, the UGC Service may follow those instructions or block the content, in its discretion.
d. Copyright Owners and UGC Services should cooperate to ensure that the Identification Technology is implemented in a manner that effectively balances legitimate interests in (1) blocking infringing user-uploaded content, (2) allowing wholly original and authorized uploads, and (3) accommodating fair use.
e. UGC Services should use the Identification Technology to block user-uploaded content that matches Reference Material regardless of whether the UGC Service has any licensing or other business relationship with the Copyright Owners who have provided such Reference Material (except that UGC Services may require that Copyright Owners enter into agreements with respect to the specifications for delivery of Reference Material that are commercially reasonable and that facilitate the provision of Reference Material by Copyright Owners and promote the goal of the elimination of infringing content). If a Copyright Owner authorizes specific users to upload content that would otherwise match Reference Material submitted by the Copyright Owner, the Copyright Owner should provide to the UGC Service a list of such users (a so-called white list).
f. UGC Services may, at their option, utilize manual (human) review of all user-uploaded audio and video content in lieu of, or in addition to, use of Identification Technology, if feasible and if such review is as effective as Identification Technology in achieving the goal of eliminating infringing content. If a UGC Service utilizes such manual review, it should do so without regard to whether it has any licensing or other business relationship with the Copyright Owners. Copyright Owners and UGC Services should cooperate to ensure that such manual review is implemented in a manner that effectively balances legitimate interests in (1) blocking infringing user-uploaded content, (2) allowing wholly original and authorized uploads, and (3) accommodating fair use.
g. Copyright Owners should provide Reference Material only with respect to content for which they believe in good faith that they have the appropriate rights to do so, and should update rights information as reasonable to keep it accurate. The inclusion of reference data for content by, or at the direction of, a Copyright Owner shall be deemed to be an implicit representation made in good faith that such Copyright Owner has the appropriate rights regarding such content. Copyright Owners should reasonably cooperate with UGC Services to avoid unduly stressing the Services’ Identification Technology during limited periods when Copyright Owners, collectively, may be providing an overwhelmingly high volume of Reference Material. UGC Services should reasonably cooperate with Copyright Owners to ensure that such Reference Material is utilized by the Identification Technology as soon as possible during such overload periods.
h. Promptly after implementation of Identification Technology, and at intervals that are reasonably timed throughout each year to achieve the goal of eliminating infringing content, UGC Services should use Identification Technology throughout their services to remove infringing content that was uploaded before Reference Material pertaining to such content was provided.
i. Copyright Owners and UGC Services should cooperate in developing reasonable procedures for promptly addressing conflicting claims with respect to Reference Material and user claims that content that was blocked by the Filtering Process was not infringing or was blocked in error.
4. UGC Services and Copyright Owners should work together to identify sites that are clearly dedicated to, and predominantly used for, the dissemination of infringing content or the facilitation of such dissemination. Upon determination by a UGC Service that a site is so dedicated and used, the UGC Service should remove or block the links to such sites. If the UGC Service is able to identify specific links that solely direct users to particular non-infringing content on such sites, the UGC Service may allow those links while blocking all other links.
5. UGC Services should provide commercially reasonable enhanced searching and identification means to Copyright Owners registered with a service in order: (a) to facilitate the ability of such Copyright Owners to locate infringing content in all areas of the UGC Service where user-uploaded audio or video content is accessible, except those areas where content is made accessible to only a small number of users (not relative to the total number of users of the UGC Service), and (b) to send notices of infringement regarding such content.
6. When sending notices and making claims of infringement, Copyright Owners should accommodate fair use.
7. Copyright Owners should provide to UGC Services URLs identifying online locations where content that is the subject of notices of infringement is found – but only to the extent the UGC Service exposes such URLs.
8. When UGC Services remove content pursuant to a notice of infringement, the UGC Service should (a) do so expeditiously, (b) take reasonable steps to notify the person who uploaded the content, and (c) promptly after receipt of an effective counter-notification provide a copy of the counter-notification to the person who provided the original notice, and, at its option, replace the content if authorized by applicable law or agreement with the Copyright Owner.
9. When infringing content is removed by UGC Services in response to a notice from a Copyright Owner, the UGC Service should use reasonable efforts to notify the Copyright Owner of the removal, and should permit the Copyright Owner to provide, or request the UGC Service to provide on its behalf, reference data for such content to be used by the Identification Technology.
10. Consistent with applicable laws, including those directed to user privacy, UGC Services should retain for at least 60 days: (a) information related to user uploads of audio and video content to their services, including Internet Protocol addresses and time and date information for uploaded content; and (b) user-uploaded content that has been on their services but has been subsequently removed following a notice of infringement. UGC Services should provide that information and content to Copyright Owners as required by any valid process and consistent with applicable law.
11. UGC Services should use reasonable efforts to track infringing uploads of copyrighted content by the same user and should use such information in the reasonable implementation of a repeat infringer termination policy. UGC Services should use reasonable efforts to prevent a terminated user from uploading audio and/or video content following termination, such as blocking re-use of verified email addresses.
12. In engaging in the activities set forth in these Principles outside the United States, UGC Services and Copyright Owners should follow these Principles to the extent that doing so would not contravene the law of the applicable foreign jurisdiction.
13. Copyright Owners should not assert that adherence to these Principles, including efforts by UGC Services to locate or remove infringing content as provided by these Principles, or to replace content following receipt of an effective counter notification as provided in the Copyright Act, support disqualification from any limitation on direct or indirect liability relating to material online under the Copyright Act or substantively similar statutes of any applicable jurisdiction outside the United States.
14. If a UGC Service adheres to all of these Principles in good faith, the Copyright Owner should not assert a claim of copyright infringement against such UGC Service with respect to infringing user-uploaded content that might remain on the UGC Service despite such adherence to these Principles.
15. Copyright Owners and UGC Services should continue to cooperate with each other’s reasonable efforts to create content-rich, infringement-free services. To that end, Copyright Owners and UGC Services should cooperate in the testing of new content identification technologies and should update these Principles as commercially reasonable, informed by advances in technology, the incorporation of new features, variations in patterns of infringing conduct, changes in users’ online activities and other appropriate circumstances.

Shneiderman的八個經典使用者介面設計準則
Shneiderman的八個經典使用者介面設計準則是設計一個互動作品的最佳指南。
1.取得一致性
類似的情況應該有讓使用者有一致性的操作。在提示、選單與說明文件中，應該採用同樣的名詞。並且保持命令的一貫性。
2.讓重度使用者使用捷徑
當使用頻率增加時，使用者會希望減少互動的次數、讓每次的互動能夠一次做更多的動作。縮寫、功能鍵、隱藏功能與綜觀全局的功能，對專家來說非常有用。
3.提供有意義的回饋
當使用者做出一些動作時，系統應該提供回饋。越頻繁的動作，其回饋的強度可以低一些。越重要或不尋常的動作，其回饋強度應該要顯著一些。
4.設計對話產生結束
一連串的動作應該被組織成開始、中間、結束三部份。當動作結束的時候，要提供回饋讓使用者知道動作已經完成。在做下個一連串的動作之前，先告知使用者整個流程，能夠減輕使用者的壓力、提高滿意度。
5.提供簡單的錯誤處理
最好不要讓系統有嚴重錯誤的可能性。如果還是造成錯誤，系統應該能夠偵測出出來，並提供一個簡單、使用者可以理解的錯誤處理方式。
6.允許回到上一步
這個功能可以減低使用者的焦慮，因為使用者隻到做錯了可以重來。這個功能鼓勵使用者探索不熟西的選項。回到上一步的功能，可以包含一個、或是一連串的動作。
7.滿足使用者控制的需求
有經驗的使用者強烈的感覺到他們在控制系統，做出動作之後，系統提供回饋。系統設計上要讓使用者作為動作的觸發者，而不是回應者。
8.減少短期記憶需求
人類的短期記憶有限，因此顯示上要保持簡單、能同時顯示多頁資料以減少視窗切換頻率，減少記憶指令和動作順序的時間。
