along the way we all learned some things

slide-116
SLIDE 116

▫︎ events are awesome ▫︎ events suck ▫︎ taking on new languages is scary, but exciting ▫︎ because javascript (WAT?) ▫︎ API design is really really important ▫︎ asynchronicity, wait(10.seconds()), is tedious ▫︎ silo’d metrics suck ▫︎ just saying “devops” doesn’t make it devops (and it’s really

scary to devs and ops)
