The theming firehose (NB for designers & front-end developers new to Drupal) | rare pattern

You don't get to construct your pages from scratch, building out essentials, never a wasted div, never an extraneous class. No, you have to flip the entire process around. With Drupal you're getting markup shot at you from a firehose, and as a themer you need to sop it all up and make it pretty. Don't spill a drop.

php_packages=`dpkg -l | grep php | awk ‘{print $2}’`

sudo apt-get remove $php_packages

sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

sudo mkdir -p /etc/apt/preferences.d/

How to auto start services on boot in Centos / Redhat?

To auto start services in Centos or Redhat OS, you can use builtin chkconfig utility. It is located in /sbin directory. If you are a regular user (non-root), then /sbin may not be in your path. Therefore, you may have to use the full path to access the chkconfig utility.

To auto start a new service:

  • Find out the name of service’s script from /etc/init.d/ directory e.g. mysqld or httpd
  • Add it to chkconfig
    sudo /sbin/chkconfig --add mysqld
  • Make sure it is in the chkconfig.
    sudo /sbin/chkconfig --list mysqld
  • Set it to autostart
    sudo /sbin/chkconfig mysqld on

To stop a service from auto starting on boot

  • sudo /sbin/chkconfig mysqld off
