Lately...
I have SELinux working in Ubuntu. I've had to do a few tweaks to make it work. In order to get the SELinux Troubleshooter GUI working (not needed but nice to have), I need to do some more research to figure out why it's not working.
I had SELinux perfect in Fedora and was doing all of it from the command line.

I found out that the newer versions of Google Earth can be used as a flight simulator.
