[转] 苹果 Firefox 输入框缺字问题
【苹果】解决Firefox 1.5.0.2 mac版缺字的问题？
呃……今天不知道脑子进水了还是怎么回事……边看notes还边研究firefox的缺字问题……
Firefox 1.5版出来后，应该说在mac里缺字问题得到了相当程度的改善……网页已经基本能看了……
但是在网页输入框里还是会缺字……比方说，Google搜索工具栏里的输入框……一直很郁闷……但又不至于郁闷到偶去研究究竟如何解决……
呃……现在，大概是知道了……
- 在firefox preference－Content里将Default font选择为Hei。
- 在firefox.app（大家都是放application目录的吧？扩展名有可能被隐藏）这个文件上点右键，选择show Package contents。
- 进入Contents-MacOS-defaults-profile-chrome 目录
- 建立一个内容为：
input{font-familly:Hei}
textarea{font-family:Hei}
名为userContent.css的文件。 - 保存，重启firefox。
中文缺字问题应该不会再出现了……不过……偶没有对日文、韩文等等其它文字做测试……但，即便这些文字缺字，也应该可以通过往userContent.css里两个font-familiy添加相应的字体名称搞定。
似乎选Hei并不是最理想的字体……选 Times等别的什么会更好……
不懂了～

There is never more than one question in a DNS message
There is always one question in a DNS message; it includes the domain name and the requested datatype and class. There is never more than one question in a DNS message -- the capability of handling more than one would require a redesign of the message format. For one thing, the single authority bit would have to be changed because the answer section could contain a mix of authoritative and nonauthoritative answers. In the present design, setting the authoritative answer bit means that the name server is authoritative for the zone that contains the domain name in the question section.
For you sticklers for detail, there is a time when the number of questions in a DNS message isn't one: in an inverse query, when it's zero. In an inverse query, there is one answer in the query message, and the question section is empty. The name server fills in the question. But, as we said, inverse queries are almost nonexistent.
