BLUE1647, IoT, & ChicagoRuby

BLUE1647 is an amazing maker space on the South Side of Chicago. Once per month, ChicagoRuby hosts an event at the space. This month featured the Internet of Things (IoT). What does IoT mean for Ruby developers? How can someone with a web development background begin exploring IoT? And why would a web developer care? This is an updated version of the presentation delivered at ChicagoRuby on 12/1/2015.
