This is a very good post because it explains the reasoning behind the code very well. It starts out with explaining the problem, and presents a simple solution to the problem. Then it explains the short-comings behind the solution and then refines the solution further. I find that it is exactly the way I learn, even my moderate understanding of somewhat complex stuff has always evolved from my understanding of simpler stuff. Wish more people wrote this way :)
