What programs do you make sure are installed on a new Linux install?

Just wondering what programs (aside from the coreutils/X11 and other
elements that make up a basic install), do you consider to be a vital
part of YOUR Linux install?  What are the little additional tools that
you can't live without, or just consider to be necessary that maybe
others wouldn't?

For me, its

    - xpenguins
    - fvwm(3)
    - oneko
