解决方法就是把浮点数转换成整形。

那么有没有更便捷的随机方法呢?

答案就是使用arc4random,它就藏在C语言标准库(Standard C Library)当中.文档对于它的描述是:

The arc4random() function uses the key stream generator employed by the arc4 cipher, which uses 8*8 8 bit S-Boxes. The S-Boxes can be in about (21700) states. The arc4random() function returns pseudo-random numbers in the range of 0 to (232)-1, and therefore has twice the range of rand(3) and random(3) .

arc4random既使用了arc4加密算法避免seed重复,并且比random的取值范围(2**31)-1整整大了一倍!那么有什么理由不使用它呢 :-)

在网站程序里用方法很简单：使用url encode把中文转换成16进制的编码就行了。 php直接调用urlencode()函数。 rails使用URI.encode()函数。
如果使用的是gchartrb，则把最后的to_url换成to_escaped_url就行了,不用自己调用encode。 c#使用Server.UrlEncode函数。
其他程序都一样各自调用API里的url encode就行了~ 于是中文等不能直接显示的非拉丁语系文字转换以后就可以了，但是CJK中唯独中文有一个BUG。

就是使用了中文以后半角数字(2,4,7)部分不能正确显示。

如图：

英文

中文

日文和韩文

这是由于google绘制图片的程序调用的中文字库的关系。

Movable Type missing keywords and description meta tag at the template.
SEO has not measure the standard too much, but I suggest you better do this than doing nothing.

“Better than not” that said the exact keywords in HEAD and that the description was not put to much more like that, so I’ll just follow the following points.

  • keywords: 5, 6 and each other the same page.
  • description: Approximately 100 characters or less.

btw,if you find out this article via the search engine, I guess you better do that :p

This is the only consideration of the following templates and Movable Type

<mt:If name="main_index">
<meta name="robots" content="all" />
<meta name="googlebot" content="index, follow" />
<meta name="keywords" content="put,your,keywords,here" />
<meta name="description" content="<$mt:BlogDescription$>" />
<meta name="revisit-after" content="1 days" >
<mt:ElseIf name="archive_index">
<meta name="keywords" content="<mt:Entries lastn="2"><mt:If name="first"><mt:EntryCategories glue=","><$mt:CategoryLabel regex_replace="/[0-9]+/",""$></mt:EntryCategories><mt:ElseIf name="last"><mt:EntryIfTagged>,<mt:EntryTags glue=","><$mt:TagName$></mt:EntryTags></mt:EntryIfTagged></mt:If></mt:Entries>" />
<meta name="description" content="<mt:Entries lastn="5"><$mt:EntryTitle encode_html="1"$>,</mt:Entries>" />
<mt:ElseIf name="entry_template">
<meta name="robots" content="all" />
<meta name="googlebot" content="index, follow" />
<meta name="keywords" content="<$mt:EntryKeywords$>" />
<meta name="description" content="<$mt:EntryExcerpt$>" />
<mt:ElseIf name="page_template">
<meta name="robots" content="all" />
<meta name="googlebot" content="index, follow" />
<meta name="keywords" content="<$mt:PageKeywords$>" />
<meta name="description" content="<$mt:PageExcerpt$>" />
<mt:ElseIf name="archive_listing">
<meta name="keywords" content="<mt:Entries lastn="2"><mt:If name="first"><mt:EntryCategories glue=","><$mt:CategoryLabel regex_replace="/[0-9]+/",""$></mt:EntryCategories><mt:ElseIf name="last"><mt:EntryIfTagged>,<mt:EntryTags glue=","><$mt:TagName$></mt:EntryTags></mt:EntryIfTagged></mt:If></mt:Entries>" />
<meta name="description" content="<mt:Entries lastn="5"><$mt:EntryTitle encode_html="1"$>,</mt:Entries>" />
</mt:If>


It inculdes Main page, Archive Index, Blogs, Pages, Blog List
edit the keywords, description etc, and insert this code in your HTML Head of template and Publish blog.

Now, It’s done, You just need to write keyword for every blog on bottom.
