Folks.
Thanks you for all the comments.

100% Agreed. I should have double checked and proof read it thoroughly before publishing it. My bad.
I relied more on Microsoft word than my English. Microsoft word is more forgiving. Looks like you are not. I was focusing more on the actual technology rather than English language.
However when writing articles on technology there is no hard and fast rules.
I will be more careful next time.
Note: Microsoft word complains that "My Bad" is a fragment and consider revising.
