Mashup
(web application hybrid)
From Wikipedia, the free encyclopedia
A mashup is a website or application that seamlessly combines content from more than one source into an integrated experience.
Content used in mashups is typically sourced from a third party via a public interface or API, although some in the community believe that only cases where public interfaces are not used count as mashups. Other methods of sourcing content for mashups include Web feeds (e.g. RSS or Atom) and JavaScript.
Many people are experimenting with mashups using eBay, Amazon, Google, Windows Live, and Yahoos APIs.

Document Object Model
From Wikipedia, the free encyclopedia
Document Object Model (DOM) is a description of how an HTML or XML document is represented in a tree structure. DOM provides a structure that facilitates access to the elements of an HTML or XML document by scripting languages with object oriented features (e.g., JavaScript).
Various interfaces were initially implemented by web browsers to manipulate elements in an HTML document through JavaScript. This prompted the World Wide Web Consortium (W3C) to create a series of specifications to standardize implementations for increased interoperability; thus the W3C Document Object Model[1] (W3C DOM) was born. The W3C specifications are platform and language independent. The previous vendor-specific interfaces were dubbed intermediate DOMs.
A simple example of its use is as follows:
To access an element in the DOM, the programmer could type document.getElementById("elementID")[2]. This is an improvement over previous Web browser implementations of DOM element access. Internet Explorer, before coming into DOM compliance, required the developer to access the DOM via arrays of similar elements; for example, document.forms[0] for the first (zeroth) form, or document.images[2] for the third image on the page[3]. While this was usable, it was more cumbersome than methods defined by the W3C DOM. The Gecko rendering engine, which exposes the DOM interface in Mozilla Firefox and many other browsers, has been W3C‐compliant for quite some time.
The tree-based implementation requires that the entire content of a document be parsed and stored in memory. Hence, DOM is best used for applications where the document elements have to be accessed and manipulated in an unpredictable sequence and repeatedly. If the application involves a sequential or one-time selective read or write per processed document, DOM presents a considerable overhead. The sequential SAX model is advantageous in such a case in terms of speed and memory consumption.

失意體前屈
維基百科，自由的百科全書
(重定向自Orz)
失意體前屈（最常見的造形為Orz），是一種源自於日本的表情符號（又稱心情圖示）。
失意體前屈，原本指的是網路上流行的表情符號：＿|￣|○ 它看起來像是一個人跪倒在地上，低著頭，一副「天啊，你為何這樣對我」的動作，雖然簡單卻很傳神。在初期，並沒有人對這個符號起個名字，「失意體前屈」這 個名字也是後來才出現的。據說是某個餐廳的座墊上繡著這五個字，至於在這之前又是誰想到的，目前尚未釐清真相。
後來，又有人發現，用簡單的三個英文字也可以表現這個動作，於是Orz就開始流行了。接下來，更有orz的日誌軟體、日誌網站相繼出現。在2004年後，於日本、中國大陸、香港與台灣儼然已經成為一種新興的網路文化。
這種文字可以寫作Orz、Oro、Or2、On_、Otz、OTL、sto、Jto、○|￣|_等，但其中以「Orz」最為常用；並有混合型，如表示無可奈何的「囧rz」。「囧」的原意是大明，但現在大都不採用原意，而取其形，轉為表情符號，表示一臉無可奈何樣。
原始用意帶有「悔恨」、「悲憤」、「無力回天」等含意，最明顯的用法就是在於向異性表白被拒絕（失戀）的時候。orz廣泛使用後，其涵意逐漸增加。除了一開始的惡搞的「無可奈何」或「失意」之外，開始引申為正面的對人「拜服」「欽佩」的意思。另外也有較反面的「拜託！」「被你打敗了！」「真受不了你！」之類的用法。台灣搖滾樂團五月天於2005年8月發表的歌曲《戀愛ing》就有「超感謝你，讓我重生，整個Orz」一句。
在2006年1月22日，台灣的大學學科能力測驗國文科試題中，其中有一題是將被誤用的語言（被報章雜誌或是網際網路影響後的用法）改成正常的白話文，其題目範例中出現：「3Q得Orz→感謝得五體投地」一段，引起輿論相當大的爭議。教育考試制度爭議。
