VanRuby: Flipping LaunchDarkly

​VanRuby is excited to have one of our former organizers, Paulo Ancheta, present his work on Flipper on February 11th. Flipper enables developers to create beautiful, high-performing feature flags for Ruby.

​​About the talk:

​At Zipline, we used LaunchDarkly for a while. It worked well for a long time, but the per-user pricing can get pretty expensive. Here's a story of how we migrated our stack to Flipper and the challenges we faced.

​The talk includes:

• ​Techniques used in evaluating both Flipper and LaunchDarkly simultaneously to find differences in evaluation

• ​Differences between LaunchDarkly and Flipper

• ​A deep dive into Flipper expressions to mimic certain LaunchDarkly behaviours

​​About the Speaker:

​Paulo Ancheta is a software developer at Zipline who works remotely in Vancouver, BC.
