Cleaning Up Cruft: Finding, Removing and Preventing Unused Code - Michael Righi

Cruft piles up as it doesn’t hurt the system. But at some point it becomes unmaintainable and it just seems easier to rewrite the whole thing from scratch. Michael will share his strategy and tips on how to clean things up before that happen.

Bio - Michael is on Instacart’s Shopper Management team, where he makes grocery magically appear by building wages, hiring, scheduling, quality of service and other systems that scale to support tens of thousands of shoppers in real-time with minimal manual process.

Cheating on Rails with Ember - Tomislav Car

We'll talk about how we approached the migration of a complex Rails app to a Single Page JavaScript app on Ember. The case study is a Rails app that has JavaScript behaviour sprinkled on top using .js.erb templates which became cumbersome to maintain and needed to be redesigned.
We'll talk about the state of affairs for API-based Rails apps (ActiveModel serializers, the JsonApi standard etc) and how all that ties in to Ember conventions.
Why has the current architecture become a problem? Did we really need to do this? Where's the line in the sand after which you need to run a JavaScript app alongside your Rails app? We'll analyze the pros, cons and present our own experiences and decisions we made.

Bio - Tomislav has been in the industry for over a decade, wrote code in a dozen languages and worked and/or managed hundreds of software development projects.
He founded Infinum, a software design and development agency and grew it to 80 people without outside investment. He also leads the charge on Productive, a SaaS tool helping agencies become more profitable.
