!!CON 2015

The joy, excitement, and surprise of programming

May 16-17, 2015 in NYC

!!Con (pronounced "bang bang con") is two days of ten-minute talks (with lots of breaks, of course!) to celebrate the joy, excitement, and surprising moments in programming. We'll have talks ranging from "I found this new data structure and I HAVE TO TELL YOU ABOUT IT" to "hey, I don't spend most of my time programming and LOOK AT WHAT I BUILT". !!Con is for programmers, artists, tinkerers, and anyone who uses programming to do something they enjoy.
