Ubuntu 12.04 – Install Varnish 3 in front of Apache 2


Step 1: Install latest version of Varnish (3.0)

These first three lines are probably not required on Ubuntu 12.04 because the main repository already contains version 3, but you can use it anyhow. Older version of Ubuntu do need it though!

#Incremental     no
Incremental     yes

OpenPanel created apache log files per virtual host, so we don’t have to do that by ourselves. The access log files are located at “/var/log/apache2/openpanel/logs”.

Ubuntu 11.10 – Configure POEdit for Zend Framework


In this post I’ll desribe how to configure POEdit for Zend Framework in Ubuntu. However POEdit is cross platform compatible and has the same GUI on Windows and Mac, so for these platforms you can also follow several steps below.

If you don’t have POEdit installed yet, open a terminal and execute:

apt-get install poedit

Now start the application with “Alt + F2″ and type “poeditor” and double click the icon. If you start POEdit for the first time, you’ll see the preferences dialog.

Append ” -L php” to the end of the “Parser command:” text field.
