How to remove ‘Welcome to the Frontpage’ title in Joomla! 1.5

Posted October 28th, 2008 by caker

If you install new Joomla! 1.5 on your server, you get the ‘Welcome to the Frontpage’ title on your Frontpage. Sometimes, it is difficult to find, where you can change this title.

Go to your Joomla! 1.5 Administration site and login. In your administration site go to:

  • Menus - Main Menu (now you are in: Menu Item Manager: mainmenu).
  • Click on ‘Home’ link to edit this link (you are now in: Menu Item: Edit).
  • Click on Parameters System and change or delete the Page title.
    • If you change the Page title, changed title will be displayed on your Frontpage as a title.
    • If you delete the Page title, Menu link will be displayed on your Frontpage as a title (in the present case ‘Home’ will be displayed as title, because ‘Home’ is the name of the link to the Frontpage).
    • If you don’t want to display any title, set Show Page Title below Page title parameter to ‘No’.
  • Don’t forget to save changes.

解决ssh连接速度慢的问题

Posted October 17th, 2008 by cdzwm

Debian默认设置下是开反向域名解析的。我们连接ssh/ftp的时候就会有一个比较明显的延时，大概要等30秒后才能输入账号密码。解决方法有两个：


1. 将客户机IP和域名对应关系加入到 /etc/hosts上

2. 编辑 /etc/nsswitch.conf
找到 hosts 那行，将其改成下面这样：
hosts: files dns [NOTFOUND=return]

Linux中的波浪号替换

Posted October 17th, 2008 by cdzwm

1. 单独的~ 或 /之前的~，用HOME环境变量的路径取代这个波浪号。

2. ~+, 用PWD变量的值取代这个波浪号。

3. ~-, 用OLDPWD变量的值取代这个波浪号。

4. ~一个单词,　如果这个单词是一个有效的用户名，则HOME变量的值取代’~一个单词’。
