Updating Samba on Fedora 8 (fc8)

I had some trouble finding this hopefully this will help other people find it easier. We have a backup server running Fedora 8. I brought the box back online with a raid 5 and got ready to install samba but ran into some errors.

In order to fix a error while installing samba:
# yum install samba-common samba samba-swat
Error: Missing Dependency: samba-common = 3.0.26a-6.fc8 is needed by package samba

I found an update for yum:
# yum install yum-fastestmirror yum-skip-broken

Then we can install samba:
# yum update
# yum install samba-common samba samba-swat

Remember to open up the firewall:
# system-config-firewall-tui

AS3 Dynamic Text Wrapping or Flowing Around Objects

EDIT: Take a look here if you are able to use Flash Player 10. (

The Flash community is still waiting for Adobe to implement dynamic or intelligent text wrapping into Flash. So meanwhile several programmers are creating their own solutions and work arounds.

After thinking about the problem, I did a quick search and I found that actually had released a solution very similar to my own inital approach. So I took a look at their code and made some improves upon based off of their original dynamic text wrapping utility.

The improvements allow text to flow around multiple objects on the left and the right. It still utilizes BitmapData and transparent pixels around each slice, but simply manages a linked list of TextFormats to control the leftMargin. In addition, it will also accept a flash.geom.Rectangle as a bounding box to work in; the motivation for this function is to reduce the computational load.

Simply input a list of DisplayObjects for the $leftList and the $rightList. Here's the function prototype:
public static function bound($field:TextField, $leftList:Array, $rightList:Array, $wrapArea:Rectangle=null, $padding:Number=10):void;

To utilize it you would make an example call:

Where tf is the TextField which wraps around objects on its left o3 and o4 and warps around objects on its right o1 and o2.

Here is the code.

Of course, it's not perfect, but it's a starting point.
