Calculus-based CAPTCHA http://bit.ly/gBnZ2z+
Well, a bunch of refreshes suggest the questions fall into one of three categories -- one of them on the elementary school level and two somewhere around the highschool (with one using slightly more difficult notation than really necessary). Moreover, LaTeX renderer => easier OCR => not that difficult :-) Even if you aren't exactly a fan of calculus, you might like this one, though: http://random.irb.hr/latexrender/pictures/4054807cb4810f17df1f392a5118e759.gif Backup copy is at http://img202.imageshack.us/i/4054807cb4810f17df1f392.gif/
I never really caught onto calculus, and I doubt that I'm alone. (Build something that asks about computer history and I won't have any problems :-)
So, what was the first computer I used? :-P Peter _______________________________________________ Fun and Misc security discussion for OT posts. https://linuxbox.org/cgi-bin/mailman/listinfo/funsec Note: funsec is a public and open mailing list.
