Hi again.

I'm on openSUSE 12.1 x64 with GNOME 3.2. I'd like to install Octave, and at the beginning I didn't even know if there were RPM's for openSUSE, until I did a search. The Software Search site seems to have suffered radical changes since last time I used it...

But now I'm not sure how to proceed and I wanted to know if you could help me a bit. How should I generally install software? By adding the repository and installing from Yast Software Manager, using the one-click method from Software Search site, or even downloading the RPM from here and installing it? Does the one-click method recognize x86 or x64?
Why does Software Search site marks the packages as "unstable"?

I ask all of this because it's the first time I'd use one-click method and the second I'd use RPM installing, and since I only have one PC at the moment, I don't want to screw up should I make a bad step...

Thanks for your help.
