In 2010, NY Times columnist David Pogue described Square as "beautiful, simple and a joy to use." Square's dedication to user experience continues to strike a chord. Today, more than 2M merchants and individuals use Square to process $6B annually.

From magnetic stripe decoding to multi-homed data centers, Bob talks about lessons learned–what worked and what didn't–and the variety of technologies and open source frameworks concealed behind Square's simple façade.
