Turing test based on real search queries in Yandex

    The fact is that all (or almost all) search queries in Yandex , albeit in an anonymous form, are available in real time at export.yandex.ru/last/last20x.xml

    Based on this API, I made a small project on Openresty ( nginx + Lua + imagemagick ), which provides a high-performance implementation of CAPTCHA .
