INTRODUCTION
YOU’RE MY REGULATOR, MY COMPILER
▸ Scream when things go too fast / slow / are unclear
▸ Scream when cool things happen
▸ Help me when live coding, I’m suck at it. Find errors for me before the compiler do
▸ Similar to Phoenix channel, this is two way communication channel. Don’t let me do all the talking!
INTRODUCTION

▸ Let it crash mentality
“IF I HAVE TO BUILD SKYNET, KILLER ARTIFICIAL INTELLIGENT FROM TERMINATOR MOVIES, I WOULD USE ERLANG AND ERLANG VM. MOSTLY BECAUSE IT’S UNKILLABLE AND KEEP COMING BACK!”
