As Mr. Robot Season 2 comes to a close, the show's attention to detail may feel almost overwhelming. Looking back on the season is like staring into an abyss of plot lines and technical tricks. So we waded through it all and pulled out seven favorite hacks, easter eggs, and tidbits of the season that exemplify the show's impressive commitment to hackery verisimilitude, ranked by our highly subjective taste in nerd-cred references. In episode four, Darlene mentions that she's set up a hack to get extra clicks on her Postmate delivery service affiliate link, thus generating money she can use to order takeout. Even if you're not quite on Darlene's level of thrift--or grift--you've probably used your second email address at some point to sign up for a service again and get another new customer offer or deal.
