UPDATE 5/2013: You can now do this with Gnome Tweak Tool. Install it with:

yum install gnome-tweak-tool

Then open it and click on Windows then "Windows focus mode" to Mouse.

The other older way is to do the following:

Type the following to add focus follows mouse in Fedora 15 and up with gnome-shell:

gconftool-2 -s /apps/metacity/general/focus_mode -t string mouse

This will copy a file system from the "/source/dir" to the "/destination/dir".

Note: The source directory can also be / and it will copy correctly.

cd /source/dir
tar -cf - . | ( cd /destination/dir ; tar -xpvf - )

The following will explain how to setup a local Fedora 12 yum repository. This example shows how to setup a local copy of the the "fedora-updates" repo. The same method can be used to also make a local "fedora" repo.

First install and setup Apache with the following:

yum install httpd
chkconfig httpd on
service httpd start

Now create the updates directory.

Go to the following menus in Firefox:

Edit->Preferences->Applications

Look for the "mailto" Content Type and click the drop-down. You should now see "Use Gmail" as an option. Select it and click Close.

Now when you click on any mailto link it will send the email in GMail.

NOTE: if you are running an older version of Firefox you many need to manually register GMail as a mailto option. The following explains how to do that.

First login to your Gmail account in a tab.

Do the following to setup GDM to auto login with a specific account. Also setup the GNOME keyring to not prompt you for a password when connecting to a saved wireless network. First, edit the /etc/gdm/custom.conf file and add the following options: NOTE: Below is the older method that works with Fedora 12 and under:

[daemon]
TimedLoginEnable=true
TimedLogin=username
TimedLoginDelay=5

NOTE: This method works with Fedora 13 and up:

cd /usr/share/mythtv
vi library.xml

Add the code below in whatever order you would like it to show in the Menu:

   <button>
     <type>STREAM</type>
     <text>Hulu Desktop</text>
     <action>EXEC /usr/bin/huludesktop</action>
   </button>

Now you can find the Hulu Desktop menu option by going to:
Media Library -> Hulu Desktop

UPDATE (04/11/2010):

After updating to MythTV .22 the above location of library.xml has changed.

It is now stored in:

yum install privoxy
yum intall tor
cd /etc/privoxy
mv config config.ORIG

vi config

Put the following contents in the config:

yum install privoxy
yum intall tor
cd /etc/privoxy
mv config config.ORIG

vi config

Put the following contents in the config:

Untar latest source (version I modified) in /usr/src/mremote.

Run the following:
cd /usr/src/mremote
make
make install
cp mrlauncher /usr/local/bin
cp mouseremote /etc/init.d/
chkconfig mouseremote on
service mouseremote start

Add the following to /etc/X11/xorg.conf:
(note the AutoAddDevices option allows it to use the mouse/keyboard section below)
