This is the command to print all regular files in the src folder but excluding all files within the .svn folders:
$ find src -name .svn -prune -o -type f -print
where -o is the or operator.

If Ubuntu does not recognize the wifi adapter, use ndiswrapper and Windows XP driver instead:
Install the needed Ubuntu packages:
$ sudo apt-get install ndisgtk
If there's no Internet access, the needed packages are available from the Ubuntu live CD under the directory /pool/main/n . Install both ndiswrapper and ndisgtk .
Download and extract the Windows XP driver for your wifi adapter.
Install the Windows XP driver:
Browse to System/Administration/Windows Wireless drivers
Click Install New Driver
Select the .inf file, then click Install
Connect to wifi networks as you normally do.

I just installed Ubuntu 11.04 desktop on my old Dell laptop, but the cdrom is not auto-mounting. Normally this simply works.
I tried various things like adding cdrom to /etc/fstab and installing halevt (which failed), none worked. However, I found out that despite talks of using gnome-volume-manager etc, at least for this version of Ubuntu automount is managed by Nautilus (file manager): start gconf-editor and navigate to /apps/nautilus/preferences/ , media_automount should be checked (but it's checked by default, unless you changed it).
In the end, I wasn't able to make cdrom automount, although USB drives automounted fine. Instead of wasting more time to diagnose the problem, I manually mounted the cdrom drive:
$ sudo mount /dev/cdrom /cdrom
