Time Travel Debugging - Getting Back to (Developing) the Future
by Rudy Jahchan

Jumping JIRA-watts! Your development has been cruising along at 88mph when suddenly your app is crashing out with bugs. Now you’re stuck in old parts of your code, unsure how you got in this state and what to do to get your timeline back on track. Enter Time Travel Debugging: tools, techniques, and patterns that help you quickly discover WHAT the problem is, WHEN it occurred, and WHICH changes will result in the best possible future … or futures! With examples from Git, Elm, React/Redux, and even Ruby, this talk will demonstrate how easy it is to get started and highlight what to watch out for. Inspiration will strike you like a lightning bolt and we’ll get you BACK TO (developing) THE FUTURE!

DDD-rail your Monorail
by Andrew Hao

The scene cuts to the offices of Delorean - the hottest time-transport startup in town (“it’s like Uber for time travel!”). Beneath the glitzy face of the fast-growing company, we find a defeated engineering team struggling with a large Rails monolith, complete with the battle scars of anemic domain models, spaghetti code, and cut corners. The team is shipping fewer features while battling increasing rates of unexpected regressions. The team wants to break up the monolith to combat complexity, but where do they begin? Join the team as they turn to three Domain-Driven Design (DDD) techniques to discover key domain insights and attempt to design their way out of the monolith mess into a well-defined, cleanly segregated, and service-oriented future. Will they succeed, or will the inexorable tides of time and entropy forever trap this team in the past?

We will provide pizza and drinks (beer and non-alcoholic drinks), wi-fi, cool vibes and killer talks.
