Ask HN: Python+Ruby hackers - which OS/distro are you using?

I was reading somewhere that a good way to choose an OS is to use the same one that your future communities will be using, so I was wondering - what OS are python and ruby hackers using? If Linux, please specify the distro, as that is basically what I am choosing between.

I am sure there would be no issue with Ubuntu, Linux Mint, Mandriva or OpenSUSE, so it makes sense to use the one most of you guys are.
