Dumbest CAPTCHA ever. It's a math problem - which computers are great at - in highly readable text; which they're pretty good at. I expect someone talented could break it in an automated fashion in a day or less. I don't know why they don't just throw up an fairly large image of a bunch of animals, then say "Click the cutest kitten" or something that's purely subjective, and relies on human recognition abilities rath…

Hmmm, perhaps this is the first of many in a dystopian future of human CAPTCHAs... "Please solve this equation in 200ms or less. Sorry, no humans allowed."

Once at MIT a blind student was showing me his screen reader. I couldn't make sense of the sounds at all, and asked if it was in some special code. He said no, it was normal language, just really fast. He had it read the current line on his terminal (this was late '80s). I could see the words it was supposedly reading, but I still couldn't map them to the brief burst of sound that came from the screen reader. So mayb…

(Was it Sam H.?) When I was at MIT I had a lab partner who was blind for I think 6.002 or 6.003. I remember that one side-effect of using a screen reader was that he easily "recited" code, which I don't think most sighted programmers could do fluently. Of course, in order to understand what he was reciting, my only hope was generally to try to type it into a text editor, format it and look at it. (And it's also hard…

It wasn't Sam H. I don't recall his name.

Most of these are really easy. I got a partial derivative of a constant. And honestly, if you can't answer basic math questions, you probably have no use for a quantum random bit generator.

I got "find the least real zero of the polynomial: -7 * 4 - 7". Somehow I doubt "mu" would be accepted.

(That sort of think has only shown up once over multiple refreshes though.)

My mom and I used to take turns reading the code listings from magazines like Compute! and RUN to each other and typing them in. It took forever. I definitely find it harder to do that with punctuation heavy languages these days (not that I'm typing much code in from magazines anymore).

I like that captcha because I can do it in my head which makes me feel special. Too bad there isn't a button just to check the captcha for those of us who don't want to sign up for an account.

Ha, by this logic, a large majority of the current world population aren't humans :)

Aristotle is very very disappointed with your logic, my friend. http://en.wikipedia.org/wiki/Inference#Examples_of_deductive...

I think you've misunderstood his post (or I've misunderstood yours (my friend))). He was saying that the linked website was illogical in using a method to distinguish humans from machines, that most humans would fail at. Grandparent wasn't attempting to construct his own logical argument.

The real WTF with this captcha is that to get a new one they recommend you reload the page, which will clear out everything you just typed into the form (since you probably typed that all before getting to the captcha), which is retarded.

If you try to be smart and just put in a known wrong answer in hopes that it'll keep the form data and give you a new question, you get dumped to a validation page which tells you you're wrong and then tells you to go back and reload the page, which is also retarded. You still come out ahead because when you hit the back button you should get a new captcha and the browser should have saved your form data, but man, this page belongs in the UX hall of shame regardless of how you feel about math in your captchas.
