    Why did you duplicate an existing question and then answer it yourself? stackoverflow.com/questions/6172557/… stackoverflow.com/questions/5153590/… Commented Jul 19, 2011 at 23:08
  • @dhg: I could not find that question on SO, that's why. I answer my own question since I prefer using SO as a knowledge repository instead of taking a note on my tiny hidden blog or making a mental post. Thanks for the link, I agree with closing with duplicate. Commented Jul 21, 2011 at 7:41
