I am not much a writer kind of person. If you drop a math puzzle, probably I will do it in better way. But sometimes it is necessity to do thing even though you are not good at it. Just like this Open Letter. Tekpub is wonderful endeavor from Rob Conery and one of his friend James Avery . I know Tekpub because of Rob Conery . You can consider me in his fan club, if he is having one.
