How To Turn Off the Keyboard Beep in Fedora & Gnome

The beep that occurs when working at the command-line or inside a text editor is not controlled by Gnome settings. Instead, it is controlled by a terminal profile. Open a terminal, right-click and select 'Edit Current Profile'. Then uncheck the 'Terminal Bell' checkbox.

Set Mode Failed Invalid Argument for Wireless Linux Configuration

I am trying to get the wireless networking working on Fedora installed into my HP dv9000 laptop when I ran into this error. The problem was caused because the system was trying to set the wireless mode to be AUTO instead of MANAGED. Update: I ran the iwlist command and found out the information that I needed to get the wireless connection working.
[root@localhost network-scripts]# /sbin/iwlist wlan0 scan
wlan0     Scan completed :
          Cell 01 - Address: 00:16:B6:1F:2B:CC

The important bits are bolded - the ESSID, Mode, and Channel. Use the system-config-network command to set the properties of the wlan0 connection. I'm publishing this blog from my laptop via a wireless connection so I know my system is now working correctly.
