Switch from Windows to Linux

I will gradually switch my platform from Windows XP to Linux (Ubuntu 9.04) due to various reasons. For a layman to Linux like me, configuration is really a headache.
In this blog, I will post solutions (in fact zz la :)) to some common problems.

(1) Chinese input
There are several Chinese inputs for Linux like scim, fictx and ibus, etc. I choose fcitx finally (do not ask me which one is the best, I only tried fcitx and it is not bad) .

gives the good solution including square font issue.

(2) Java configuration

(3) Java IDE
-- Eclipse: This is very simple , just untar your tar file to some folder and then run it!
-- http://www.javadesign.info/SystemsHardware/OS/Ubuntu/install-netbeans-on-ubuntu gives how to install Netbeans in Ubuntu.

(4) Latex & editor
http://wandsea.com/blog/331.htm gives how to install latex, it is very simple....
texmaker is my current tex editor, not bad, try it.
the command to obtain texmaker is : sudo apt-get install texlive texmaker

(5) Evolution
Using an Email client like Evolution on Ubuntu is not difficult. Here I only describe how to configure Evolution to connect to MS exchange
- set Exchange as the server type
- set username as domain/name (domain is very important)
- set OWA url (you must know OWA of your organization....)
- set set authentication type"plaintext password"
done!

(6) handle rar in Ubuntu
Archive Manager itself does not support rar, so to unrar a rar file, the program "unrar" is needed. Get it by the command sudo apt-get install unrar
How to: go to the directory where your rar file is in and type the command:
unrar x filename.rar
