I wanted to include it in the original piece, actually, and I have tried to retrieve it again just to answer to you, but both attempts failed :( I am fairly sure I read it here on HN, but I tried looking for the author's surname in comments and could not find it (or some obvious misspellings). Sorry, if I ever manage to find it again I will update my piece too.
