Just a random person on the internet pining for an OpenPOWER system, waiting for the wallet to catch up to my aspirations.

Same person as torpcoms on the Level1Techs forums, Github, Wikipedia, Reddit, Diaspora ( server), GNU Social ( server), probably some other places as well.

I have timemarked a few videos over the past few months; I am keeping a copy of the Power-related ones on this wiki in case they are useful to someone.
