Awesome captcha!

http://random.irb.hr/signup.php Look at the bottom of the page. Now come on, how many captchas do you know of that require a person to do calculus lol.

 

[Gunslinger08]

I hate captcha.

 

[sponge008]

Haha that's great.

keeps the riffraff out I suppose. Oh and if you refresh it a couple of times you can get a simpler order of operations equation.

 

[Megatomic]

lol, that's actually pretty neat.

 

[frostedflakes]

Nice, lol.

 

[Jeff7]

Damn, first I got one that was a third-order polynomial.
Refreshed for an "easier" problem. Now it's giving me a partial derivative problem. Damn calculus.

After 15 more refreshes, it finally gave me something without calculus, and this is it:

5-(-4)+0*4*(-3) = ?


Partial derivatives to basic arithmetic.

Wait, what is captcha?

 

[jinduy]

they must lose out on potential users... maybe for the better

Apparently, graphical things that make you prove that you're not just a spambot.

 

[imported_Salvatore]

woohoo i got it! but now i have an account for some weird site because I also filled in everything else...

The people who would be requesting the sites services better damn well be able to answer the captcha questions, otherwise they should question why they are there to begin with

Exactly, If you understand why REAL random numbers are important and how to use them, then you will understand he captcha. If not, then stick with your pseduo random number generators.

cool, I signed up for their site just to check if my mental math was correct. (I had a derivative evaluated at pi)

yeah, 2 refreshes and both that I saw were simple Order of Operations algebra.

also, first time I knew that this was called captcha...

Heh, now I have another answer for my students when they ask "when am I going to need to know math in the real world?"

I'll pull up this page for them to see and say "this way, they keep the riff-raff out."

 

[AmberClad]

I hate those captchas with the randomly generated sequence of letters/numbers. I guess they're designed to defeat simple programs that can recognize symbols, but they make things so distorted that even a human might have trouble figuring out what the symbols are and if they're lowercase/uppercase.

 

[Cogman]

I'm surprised you guys haven't heard of theses things being called captchas, Haven't you ever had to sign up for something on the internet? Just about everything now-a-days uses a captcha of some sort.

 

[GodlessAstronomer]

I got a partial derivative of a function of only one variable

 

[drinkmorejava]

lol, I just signed up to see if I got the right answer.

the world hereby hates you.

 

[LordMorpheus]

The ubuntu forums use a similar captcha.

 

[oogabooga]

isn't microsoft generating one where you get 8 pictures of either puppies or kittens and it asks you to identify the kittens?

That is a perfect Captcha for that site.

 

[eits]

i don't get it...
