CakePHP, Eclipse PHP plugin initial setting....configure .ctp file in Eclipse

I already had Eclipse 3.6 but not PHP development environment.

PHP development environment in Eclipse is called PDT.
I followed the instruction in the following page.
http://wiki.eclipse.org/PDT/Installation#From_Update_Site

Then, I wanted to use Aptana plugin.
I found the instructions in the following page.
http://docs.aptana.com/docs/index.php/Plugging_Aptana_into_an_existing_Eclipse_configuration

Now,  you want to configure .ctp(view) files in Eclipse as php files.

• Firstly open the  Eclipse workspace.
• Now go to Preferences from Window menu.
• From Preference click on the General tab from the list.
• Now click on Content-Types under General  tab.
• On the right panel in the Content-Types, expand the Text tab.
• Select PHP Content-Types .
• Now click on the Add button and type the fie extension e.g. *.ctp in the content type input field.

Gimp changing the interface language back into English

So today, I installed Gimp to play with some pictures.
I'm using Vista by the way....yes...can't wait to change the OS.

Anyhow, go to C:\Users\<User Name>\.gimp-<version>
It's a hidden folder so you have to set the folder option to show hidden folders.
Delete .gimp-<version> folder.
Start Gimp, it should be in English.

Wordpress Contact Form Problem: Mail Not Sent

I've used Contact Form 7 Plugin for my website contact form.
Installation, super easy.
Sending email, super easy....but

I had this problem.
I see a response message “Your message was sent successfully” with green border, but I never receive a mail for that.
Which was exactly an FAQ at Contact Form 7 site.

I know the cause can vary according to your server.
In my case, the reason was postfix wasn't working.

So I typed the following command, and everything works fine.
sudo /etc/init.d/postfix start
sudo /sbin/chkconfig postfix on
