This question got voted as a duplicate of this other question.
Both before and after closure it got edited to avoid being a duplicate.
Despite the edits, people voted to keep it closed.
I am obviously biased, having answered it (and that's why I have not used my reopen vote, being a mod it would count for 5), but I can't see it being a duplicate in its current form. Can someone explain why they think it is a duplicate?
