這些天兵似乎還不知道自己在幹麼，她們大聲疾呼「We know what they’re doing in there. They’re hacking pythons. It’s barbaric and we won’t leave until the last snake has been saved」，秀才遇到兵，有理說不清。

Implementing this in canvas presents two main challenges: drag & drop and performance. I tried several approaches to solving these problems, and ended up using a multilayer solution which renders only the active image on the top-most canvas layer. This allows us to have drag & drop without needing to redraw every image each time one of them is dragged.

flickr extra=original_format
flickr api 有一點小變動，現在 getPublicPhotos 傳回來的 secret，原圖(original size)的 secret 不一樣。
1. 使用者必須是 pro 帳號
2. 使用者在 setting 裡面必須有開放原圖下載。
3. request 裡面必須加上 extras=original_format，api 除了本來的 secret 之外，會多回傳一個original_secret用來組成 original format 的 url。
<photo id="2564951972" owner="95212179@N00" secret="0c5792bbab" server="3112" farm="4" title="20080608(003)" ispublic="1" isfriend="0" isfamily="0" originalsecret="5e3a85a1da" originalformat="jpg"/>
Flickr Services
Note: Original photos behave a little differently. They have their own secret (called originalsecret in responses) and a variable file extension (called originalformat in responses). These values are returned via the API only when the caller has permission to view the original size (based on a user preference and various other criteria). The values are returned by the flickr.photos.getInfo method and by any method that returns a list of photos and allows an extras parameter (with a value of original_format), such as flickr.photos.search. The flickr.photos.getSizes method, as always, will return the full original URL where permissions allow.

ADsafe
ADsafe
ADsafe removes features from JavaScript that are either unsafe or grant uncontrolled access to unsafe browser components or that contribute to poor code quality. The removed features include
* Global variables
o ADsafe's object capability model prohibits the use of most global variables. Limited access to Array, Boolean, Number, String, and Math is allowed.
* this
o If a method is called as a function, this is bound to the global object. Since ADsafe needs to restrict access to the global object, it must prohibit the use of this in guest code.
* eval
o The eval function provides access to the global object.
* with statement
o The with statement modifies the scope chain, making static analysis impossible.
* Dangerous methods and properties: apply arguments call callee caller constructor eval prototype unwatch valueOf watch
o Capability leakage can occur with these names in at least some browsers, so use of these names with . notation is prohibited.
* Names starting with _
o Some browsers have dangerous properties or methods that start with _.
* [ ] subscript operator except when the subscript is a numeric literal
o Lookup of dynamic properties could provide access to the restricted members. Use the ADSAFE.get and ADSAFE.put methods instead.
* Date and Math.random
o Access to these sources of non-determinism is restricted in order to make it easier to determine how widgets behave.

svn:ignore
另外, 上述用的是 propset 的參數來做設定, 如果在 project 中, 有些目錄或檔案是在測試時後產生, 但是並不需要 commit 進去, 不過每次 svn st 都會跑出來干擾你, 可以用 propedit svn:ingnore 來解決此問題:
1. svn propedit svn:ignore img
2. 會出現讓你編輯不想編入的檔案, 寫入
*.jpg
3. 這樣子之後 img/*.jpg 的檔案, 在 svn st 時就都不會出現囉~ :)

美狗の美容保養誌 - Differin 痘膚潤 凝膠

衡陽路32號1樓
今天去拿東西 順便就晃進去問了
痘膚潤50g 195
15g 90
美狗の美容保養誌 - Differin 痘膚潤 凝膠
50g , NT$550
15g , 忘記多少錢了 =_=
這是我自己超愛用的除痘痘粉刺凝膠 ,
不太像一般的粉刺痘痘藥膏 , 只是單純消炎跟抑制油脂分泌.
這凝膠含有Adapalene這種維生素A類化合物 ,
能夠幫助分解粉刺 且對 尋常性痤瘡(俗稱青春痘)有療效!
不過它可能有光敏性 , 所以只能在晚上使用 ,
它能夠暢通阻塞的毛細孔 , 讓毛囊細胞正常化 , 幫助油脂正常排出 , 以減少粉刺的形成.
隔天睡起來就會發現 , 臉好油 , 洗臉後發現粉刺明顯減少 , 毛孔會有比較暢通的感覺呦
台灣皮膚雷射美容中心___常用的青春痘外用藥物1
維他命A酸類的藥品，有去角質作用，可以促進表皮細胞的代謝更新，並能深入毛囊的厚壁，去除過度角化、抑制皮脂腺分泌，防止面皰粉刺形成。A酸一直是有效的青春痘治療藥物，對於非炎性、特別是粉刺型的青春痘療效最為明顯。
4.夜間睡前使用，是A酸較適合的方式。第一代的Tretinoin有光敏感性，在陽光下會有光毒性產生，只能在夜間使用。第二、三代的Isotretinoin與Retinoid雖然光敏感性降低，但是使用A酸後表皮對紫外線的防護力下降，在陽光曝露下會加重刺激敏感發生，最好還是夜間塗抹，白天配合使用防曬。

Finally, the alternative fix for IE6's memory leak is available
try finally 妙用,防止内存泄漏【转自51js】 - AJAXBBS.NET - WEB前端技术交流博客
Finally, the alternative fix for IE6's memory leak is available
Ajaxian » Is “finally” the answer to all IE6 memory leak issues?
The finally statement defines a block of code that will always be run after the completion of the preceding try block. The finally block will always be run even when an error occurs and control is passed to a catch block. The finally block will be run immediately after any catch block. Finally is a reserved word and cannot be used for anything other than declaring a final error handler for a try block.
function createButton(){
var obj = document.createElement("button");
obj.innerHTML="点我!";
obj.onclick=function(){
//处理click事件
}
obj.onmouseover=function(){
//处理mouseover事件
}
return obj;//这里由于需要返回创建的对象，所以不能把obj直接设为null. return 后obj是局部变量，不能在外部断开其与HTMLElement的引用.ie中将出现问题泄漏问题
}
var 按钮 = document.getElementsById("d1").appendChild( createButton());
按钮.做某些事();

}
obj.onmouseover=function(){

}

return obj;
}finally{
obj = null;//这句话在return 之后才执行 , 的效的解决了需在return后将obj置null的问题
}

Nest Inline Elements inside Block Elements
Give every inline element a block-level parent, and remove all block-level elements from paragraphs.
Motivation
To be valid, it is not sufficient that all the elements in a document be legal XHTML strict elements. They must also have the right relationships to each other. Browsers and other programs depend on correct placement. For instance, an li element must always be a child of a ul or ol element, and each ul or ol element must have at least one li child. Blockquotes can contain paragraphs, but paragraphs can't contain blockquotes.
Although browsers will display documents that violate these structure rules, they may interpret them differently. Furthermore, this sort of invalidity can even more seriously confuse editors and other non-browser tools that attempt to work with the HTML. For instance, as I write this, some people are having problems because WordPress is rewriting their markup in unexpected ways to try to fix blockquote/paragraph nesting issues.
When paragraphs or block-level elements are not found where they're expected, browsers and other tools guess where they should insert extra content to make them fit. They don't always guess right, and they don't always guess the same. This causes problems designing cross-browser CSS and JavaScript. Nesting your elements correctly helps browsers and tools to process a document consistently.
The main body of an HTML page consists of several kinds of elements plus text:
* Paragraphs: p, pre
* Block-level elements: address, blockquote, center, dir, div, dl, fieldset, form, h1, h2, h3, h4, h5, h6, hr, noscript, ol, table, ul
* Inline elements: a, abbr, acronym, b, bdo, br, cite, code, dfn, em, img, input, label, q, samp, select, span, strong, sub, sup, textarea, var
* Miscellaneous elements: button, del, iframe, ins, map, object, script
* Context-limited elements: li, dt, dd, tr, th, td, tbody, input, select
* Raw text; a.k.a. PCDATA
A p element represents a paragraph. However, unlike other block-level elements, a p may not contain another p or another block element such as blockquote. It can only contain plain text and inline elements. It is in some sense the lowest block-level element.
The pre element is also special in this way. It can contain inline elements, but not other block elements.
css generated content
ANSI character set and equivalent Unicode and HTML characters - .index ul li.on:before{content: "\00AB"; color: gray;}, content裡面的內容如果是html entities，必須 escape 該 content 的 unicode value:

ACID - Wikipedia, the free encyclopedia
ACID - Wikipedia, the free encyclopedia
In computer science, ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties that guarantee that database transactions are processed reliably. In the context of databases, a single logical operation on the data is called a transaction.
Atomicity refers to the ability of the DBMS to guarantee that either all of the tasks of a transaction are performed or none of them are. For example, the transfer of funds can be completed or it can fail for a multitude of reasons, but atomicity guarantees that one account won't be debited if the other is not credited.
Consistency property ensures that the database remains in a consistent state before the start of the transaction and after the transaction is over (whether successful or not).
Isolation refers to the ability of the application to make operations in a transaction appear isolated from all other operations. This means that no operation outside the transaction can ever see the data in an intermediate state; for example, a bank manager can see the transferred funds on one account or the other, but never on both—even if he ran his query while the transfer was still being processed.
Durability refers to the guarantee that once the user has been notified of success, the transaction will persist, and not be undone. This means it will survive system failure, and that the database system has checked the integrity constraints and won't need to abort the transaction. Many databases implement durability by writing all transactions into a log that can be played back to recreate the system state right before the failure.
