You’ve got to hand it to the boys (and girls) from Zagreb!

Eggheads at the Ruđer Bošković Institute in Zagreb, Croatia, are having some geeky fun with their web forms.

If you want to login to the institute’s Quantum Random Bit Generator service, you will be asked the usual questions like your username and password, but then you’ll be faced by a mathematical problem that may give you a nighmarish memories of your schooldays doing advanced calculus.

Complicated calculus-based anti-spam CAPTCHA

Hmm.. it’s a bit more complicated than the typical sort of CAPTCHA used by websites around the world to try to block spam bots and automated systems:


Sometimes, of course, these randomly-generated CAPTCHAs can go very wrong – potentially causing unintended offense to some amusement.

Somehow I don’t think the calculus-based CAPTCHA is going to catch on with the general public.

About carlos

I'm a curious person, of reasonable intellect, "on the beach" (retired) and enjoying my interest in anthropology, language, civil rights, and a few other areas. I've been a hippie/student/aerospace tech writer in the '60s, a witness to the Portuguese revolution in the ‘70s, a defense test engineer and witness to the Guatemalan genocide in the '80s, and a network engineer for an ISP in the '90s. Now I’m a student and commentator until my time is up. I've spent time under the spell of the Mesoamerican pyramids and the sweet sound of the Portuguese language. I've lived in Europe, traveled in Brazil, Central America, Iceland, New Zealand, and other places. My preferred mode of travel is with a backpack and I eat (almost) anything local. Somehow, many of the countries I have been to have had civil unrest (for which I was not responsible). I'm open to correspond with anyone who might share my liberal, humanist interests. I live in San Buenaventura, California.
