There is nothing proprietary about them.

sudo emerge -avuDUg world

–changed-use, -U:

• Tells emerge to include installed packages where USE flags have changed since installation. This option also implies the –selective option. Unlike –newuse, the –changed-use option does not trigger reinstallation when flags that the user has not enabled are added or removed.

–getbinpkg [ y | n ], -g:

• Using the server and location defined in PORTAGE_BINHOST (see make.conf(5)), portage will download the information from each binary package found and it will use that information to help build the dependency list. This option implies -k. (Use -gK for binary-only merging.)

Einstein.

He was a generally great guy and had very progressive social views, so it would be fun to talk to him about the current state of the world.

Also a lot of his theories around relativity and theories of quantum physics have been proven recently. It would be amazing to see his mind be blown when he realises both sides were right and what that means for how a theory of everything needs to look like.
