A CAPTCHA (Completely Automated Public Turing Test to tell Computers and Humans Apart) is a challenge-response system test designed to differentiate humans from automated programs. A CAPTCHA differentiates between human and bot by setting some task that is easy for most humans to perform but is more difficult and time-consuming for current bots to complete.

I had hoped not to bother you guys with it, but lately even this blog has been attacked by bots. (Just when I thought that my contributions in the first half of May were popular having 10+ comments... Alas...) So now I put CAPTCHA on it to make sure I get genuine reactions and not advertisements for whatever.
