Wei Chen’s Blog

Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!

Finally I decided to use wordpress as my Blog software!
I installed several software including phpblog, serendipity, nucleus, wiki, and wordpress. They all are very easy to install and config, and have friendly interface, I almost made my mind to use serendipity, but finally wordpress with the theme “almost spring” catched me. Its light and simple appearance is just my taste.

I am analyzing the data of [tex]\gamma + n \rightarrow p + \pi^{-}[/tex] from JLab.

[tex]\frac{d|\phi|^2}{d\phi} = \phi^* or 2\phi^*[/tex]?
[tex]\phi = \alpha + \beta i [/tex]
[tex]\frac{d|\phi|^2}{d\phi} = \frac{d(\alpha^2+\beta^2)}{d\phi} = \frac{d(\alpha^2+\beta^2)}{d\alpha} \frac{d\alpha}{d\phi} + \frac{d(\alpha^2+\beta^2)}{d\beta} \frac{d\beta}{d\phi} = 2 \phi^* [/tex]
However, in most QFT text,[tex]\frac{d|\phi|^2}{d\phi}= \phi^*[/tex].

It’s been only 5 days, since I installed wordpress V1.5, and today I noticed that v2.0 released yesterday.

1. To remove the ^M characters at the end of all lines in vi, use:
   
   :%s/^v^M//g

   The ^v is a CONTROL-V character and ^m is a CONTROL-M. When you type this, it will look like this:

   :%s/^M//g
2. Public key authentication in ssh
   cd ~/.ssh
   ssh-keygen -t rsa
   append id_rsa.pub to file server:~/.ssh/authorized_key
   make sure chmod .ssh to 700, and authorized_key to 600, or it will not work.
3. SELinux
   When I was trying to use Virtual Host or UserDir in apache, if the directory does not begin with /var/www/, then I got an access denial in the log. Finally I found it is because of SELinux. Edit file /etc/selinux/config to turn it off.
