Some questions that are fit to ask on http://unix.stackexchange.com are not fit here, but the other way around should always be ok. But is it? - (from askubuntu's point of view, of course)
My answer on the other question may sound favourable but it is really talking about the wider community (outside of Stack Exchange). There is one reason why the answer to your question is a decided no:
Unix&Linux.SE does not allow cross posting.
It doesn't matter what we say, posting something to both here and there will break their rules so please avoid doing it.
