Css样式兼容IE6,IE7,FIREFOX的写法

Published on August 31, 2008 in Tech. 0 Comments Tags: , , , , .

根据FF和IE对一些符号识别的差异,我们可以单独对FF以及IE定义样式,例子:

区别IE6与FF：

1
background:orange;*background:blue;

区别IE6与IE7：

1
background:green !important;background:blue;

区别IE7与FF：

1
background:orange; *background:green;

区别FF，IE7，IE6：

1
background:orange;*background:green !important;*background:blue;

注：IE都能识别*;标准浏览器(如FF)不能识别*；

  • IE6能识别*，但不能识别 !important,
  • IE7能识别*，也能识别!important;
  • FF不能识别*，但能识别!important;

所以标准的写法FF，IE7，IE6：

1
color:#fff; *color:#000 !important; *color:#ff6600;

firefox:白色，IE7：黑色，IE6：橙色

另外再补充一个，下划线”_”,
IE6支持下划线，IE7和firefox均不支持下划线。

于是大家还可以这样来区分IE6，IE7，firefox:

1
background:orange;*background:green;_background:blue;

注：不管是什么方法，书写的顺序都是firefox的写在前面，IE7的写在中间，IE6的写在最后面。

在笔记本上使用usb的鼠标真的是不好受，可能是由于我的这个usb鼠标的原因。再发一次配置。

Testing On Work Laptop is a Bad Idea

Published on August 27, 2008 in Tech. 0 Comments Tags: , , .

为了测试 kde4.1 （slackware-current）里面的包，我安装了，不过testing的版本的确非常不好，还是换回来了，看到又要折腾一个下午了…… 再也不在工作用的电脑上安装testing的包了，特别是这样大型的桌面环境。

Frontpage hanging CPU on Hostmonster with Cpanel

Published on August 20, 2008 in Tech. 0 Comments Tags: , , .

Frontpage hanging CPU on Hostmonster with Cpanel, It’s truth, author.exe cross most cpu time, about 99%, on Hostmonster with Cpanel. Google will find much like this. Such as this. or such as hostmonster server host266.

I think the team of Hostmonster need remove some frontpage  extensions.

使用自由软件测试HTTP服务

Published on August 18, 2008 in Tech. 0 Comments Tags: , , .

一个测试HTTP服务器极限的好方法就是模拟高负载下的HTTP服务器, 有5款自由软件是您的最好选择: curl-loader, httperf, Siege, Tsung, and Apache JMeter.

  • httperf
    测试5000次连接,每次50个请求

    1
    httperf --server=localhost --uri=/ --num-conns=5000 --num-calls=50

    高级应用

    1
    2
    3
    httperf --client=0/1 --server=localhost --port=80 --uri=/ \
    --send-buffer=4096 --recv-buffer=16384 \
    --num-conns=5000 --num-calls=50

    你也可以尝试一下一个更简单的类httperf软件http_load.

  • Siege
    和httperf类似, 上手非常简单

    1
    siege localhost

    利用sproxy连接代理服务器

    1
    sproxy -v -o urls.txt

    使用代理服务器

    1
    siege -v --internet --file=urls.txt
