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 Unfortunately, standard Yum repositories carry significantly outdated packages.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...

If you need to install PHP, MySQL, Python or other major package, you will find that the versions in default repos are old to the extent of being useless. This...

To make things more dire, centos-test and rpmforge yum repos do not carry a more up-to-date Ruby version. If you are fine upgrading to just 1.8.6, and want to use Yum, see my...

How many times have you accidentally opened a protected file with vi, edited a whole bunch of stuff in it and only at the point you wanted to save it, have you remembered that you’d forgotten to “sudo” before editing the file? If you do a lot of Unix work, I bet this has happened...

First find the revision you need to revert back to by running: cvs log screwed_up.code Once you...
