Just in case you're not - they're basically web page modules used to verify if information is being submitted by a human and not a computer or a bot. There is an "official" captcha but there are also many variations of it (of which I think Google's is the best) but they basically aim to do the same thing.
Honestly they have become so difficult to read recently that even after really straining to figure out what the hell it says, I still get it wrong... like 3 times. Today I saw something that got my attention - it wasn't a captcha, it was a simple math الخيارات الثنائية هولندا equation (like 1000+5000) which if you got the answer right, your comment was accepted.

Basically you just make a really hard equation. I mean not like the Google billboard or the Adobe building, but maybe like some simple algebra or something. At the very least it might be a funny publicity thing.
follow url I can imagine someone like Mensa having a random long ass equation as their captcha system. I don't honestly think it's a great idea for the majority of sites to use because it would really be stupid to frustrate someone who genuinely wants to read your material or buy your product. Talk about a usability faux pas.
source url On the other hand, I think this type of system is better than traditional captchas for two reasons: 1) If you get it wrong it's because you just didn't do your math, whereas if you get the original captcha wrong, it's because you couldn't read it - which pisses you off because you feel like your time is being wasted and 2) We would all do a little better to have even a little simple math back in our life let's be honest.

That's my two cents for the day.
