　　上表中讨论组中常用的一些顶级类别其中的"alt" 所讨论的内容没有其他类别那样正规。alt类别中的专题小组通常能容忍较为过火的言论，有点类似于比较激进的社会团体。

　　名称的第二部分（中间部分）表示顶级类别中的不同主题。例如：sci.biology 表示在科学这一大类中的biology（生物学）主题。Comp.os则表示计算机大类中的操作系统主题。

　　在大多数情况下，主题之下还进一步细分出特定的领域，这构成了专题小组名称的第三部分（最右边的部分）。例如：rec.autos.driving就 是在rec（娱乐）顶级类别中autos （汽车）主题下关于driving（驾驶）的专题小组。在计算机类和科学类中，常常还有名称的第四部分。例如：comp.os.ms- windows.apps.word-proc是关于计算机操作系统下，Windows软件的字处理器的专题讨论小组。

from mod_python import apache

def handler(req):
    req.content_type = 'text/plain'
    req.write("Hello World!")
    return apache.OK


    3）配置测试目录
    > sudo vi /usr/local/apache/conf/httpd.conf
	增加如下几行：
    <Directory /some/directory/htdocs/test> 
        AddHandler mod_python .py
        PythonHandler mptest 
        PythonDebug On 
    </Directory>

    4）重新启动apache服务器
    > sudo /etc/init.d/apache restart

    5) 浏览器访问
    > w3m localhost/test/anyname.py

	... Hello World!

So to simplify the implementation of Swing library they chose it to be not thread safe. The argument being that most of the GUI related work happens in the callbacks from the GUI which happen on the single GUI thread anyways. Granted - for long running tasks the user will have to do more work if he/she wants to do multithreaded activity. Not making Swing thread safe allowed them to implement the Swing which covered a lot more ground (new controls, layouts, keyboard actions, layered pane etc) in a short amount of time.

It is not that bad though - Swing does provide a mechanism to deal with the issues of threading -

• javax.swing.SwingUtilities.invokeLater(Runnable ...);
• javax.swing.SwingUtilities.invokeAndWait(Runnable ...);
• javax.swing.JProgressBar class
• javax.swing.ProgressMonitor
• javax.swing.ProgressMonitorInputStream
• SwingWorker

For more explaination of why they made that decision please see the following URLs:

The AWT is based on the OS's WIndowing System's peer objects which are inherently thread safe. That is why AWT is thread safe.
