So, sometimes when you try to run “apt-get install” on Ubuntu, you may get the following message:
Media change: please insert the disc labeled
'Ubuntu-Server 7.10 _Gutsy Gibbon_ - Release i386 (20071016)'

Suppose that you need to set up a virtual host in Apache that catches all un-matched traffic coming in to your server. There are a number of uses for this, but the main idea is that you have a number of other virtual hosts set up, but you want anything that doesn’t match those to […]
Previously, I wrote this article on how to check the status of a known system PID from PHP. I figured that I would follow it up with another short article on how to determine the process id of a running PHP script from within itself. Many google searches seem to have led people to the […]
Here is a quick example of how to do a bulk update with Propel within symfony. This is based on this code snippet on the symfony site. I thought it was extremely useful, so I wanted to post it as an easy reference for myself and others.
Suppose we had a query which looked like this:

A common task that you will need to do on a Ubuntu/Debian server is set a static IP address. By default the ip address is set through DHCP, so you will need to change that.
First edit the /etc/network/interfaces file:
sudo nano /etc/network/interfaces
Change your file so that it looks similar to the following, but replacing the specific […]
At some point you may need to have your symfony do some sort of process through the command line and trigger it through a cron job. I’ll will walk you through the steps in order to get it working properly.
The scenario:
You have a list of ids in a particular order that you want to search for in a MySQL table. Perhaps the ids were returned in this order from a search index or something else. Whatever the case is, now you want to get the results in the same order as the ids that […]
At some point you may need to figure out if a system process is still running from within a PHP application. The secret is by running a system command from PHP that returns the information for a specific process id (PID).
