A fun informative article to read

[Moltke]

I recently forgot my debit card pin number I remembered the numbers cause I always use the same ones but change the sequence and used to write it down but last time I forgot to do it and well...While I was googling for a way to generate the possible combinations for those numbers I found this article (yes, I know. I could just write all the possible combinations down in a piece of paper but I felt kind of lazy  ) http://www.datagenetics.com/blog/september32012/ and thought of sharing here. Hope you enjoy it just as I did.
