Actually, it was cross-posted to Stack Overflowcross-posted to Stack Overflow, and it has an accepted answer there. You're correct that it belonged there, but there was no need to migrate it since the OP had already posted there.
I'll add a comment to the post to make it clear.
EDIT: Based on the discussion above, I've deleted our copy of the question. We have no answers or useful comments, and the question on SO is improved and has a good answer. Our copy is just noise at this point.
