Configuring Yum Yum is a popular package manager for CentOS and RedHat Linux distributions. Unfortunately, standard Yum repositories carry significantly outdated packages. Fortunately, there are third-party Yum repositories with more updated LAMP packages which we...

If you ever need to create a Drupal core patch, you may need to check-out main branch of the appropriate version. CVS URLs for those are not easy to find, so here they are: Drupal 5:\ cvs -d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal -z6 checkout -d drupal-5 -r DRUPAL-5 drupal Drupal 6:\ cvs -d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal -z6 checkout -d drupal-6 -r DRUPAL-6...
