Having done stupid things

Gentoo is also the name of the fastest underwater swimming penguin species https://en.wikipedia.org/wiki/Gentoo_penguin and http://www.bbc.co.uk/nature/life/Gentoo_Penguin Gentoo runs on many architecture as: X86, amd64 (aka x86_64), arm, ... . Since Gentoo is a source code distribution the differences between the architectures are surprisingly small (other bot loader, other kernel source).
