This often goes overlooked on a forum full of coders, but not everyone who reads HN or wants into infosec is proficient with a major scripting language.
I'd bet being solid in python/bash/powershell would come in handy, and that having no skills in any of them may be a dealbreaker.
Highly recommend python or perl myself - and obviously know how to use bash as well.
One related suggestion: Do not become reliant on third party modules/add-ins (other than the standard library stuff) - at least when learning. Really learn how it works.
