A few students from an American university in 2000 came up with this acronym Completely Automated Public Turing test to tell Computers and Humans Apart.
CAPTCHA is an automated and random way of generating a simple challenge-response test to make sure the response is not from another computer or computer program.
It could be simple questions like 1+1 or some pictures of letters and numbers where the human reader has to check and type back in text.  If the response is good, then the next instruction will be allowed to continue.

So why do I want to write about CAPTCHA?

This is a blog and everyday I get automated postings aka Spams to my posts.  They are useless posts with links to adult, medicine or other sites that needed exposure.  Yesterday I received quite many and enough is enough I guess.   Even these posts have been marked as spams, I still have to to empty the spam bin manually.  This is quite annoying sometimes!
So here I am, I have installed a program that will ask a simple question before the user can post his/her comment.  Hopefully, this doesn’t deter my readers from commenting.
Let’s see if this CAPTCHA program will work as intended.

Come on real human readers, I need some real comments, please…  ;-)
