Tagging items to people and browsing items related to people were first implemented using taxonomy and later changed to nodereference.

When I started using drupal, I wasn't sure the best way to upgrade drupal core. I tried untarring files directly over the present directory, or untarring locally and then using an sftp client
I recently had a case where cron failed to run on a drupal site; however, there were several sites on the same server, and cron was only failing on one.
