Need to mount a samba share on your CentOS server from the command line?
Create a directory on the root:
mkdir /sharename
Then mount the share:
mount -t cifs //<servername>/<sharename> /sharename
if you type df -h you should see that your share is now mounted on the mountpoint that you created earlier.
Ever needed to connect to the remote console of the machine rather than running through a terminal services session so that you could install certain software, or reset stuck terminal services sessions from a remote location? All you have to do is type /console behind the host in the window.

I wrote a little application that allows you to play music from Pandora right from your dock. It does not take up a tab in your web browser, and it supports playing while minimized, which Safari does not. You can get it here: http://www.farmsoftstudios.com/pandora/
