Title: Migrate your service with confidence

Summary: Klarna used to run with a 15+ TB Mnesia database which powered KRED, it's largest Erlang system. Over the past two years we have migrated this database from Mnesia to Postgres with zeor downtime! During this migration project, we learned a lot about how to perform large scale migrations and how to tackle them. I will walk you through our lessons learned and illustrate along the way with real life examples and learnings from this project. I will provide three key takeaways that you can apply to any migration, no matter how big or small it may be. Consider these, the three commandments of a migration project.

Who am I: Onno Vos, 33 years old, lead engineer at Klarna and have been working with Erlang for about 7 years.

Title: LiveView keeps you warm! - Building a knitting machine UI with Phoenix LiveView

Summary: How easy is it to get started with LiveView as a backend developer? Is the "No javascript needed" true? In this talk I'll try to give answers to these questions by telling the story of how I used LiveView to make a new user interface for an old Passap E6000 knitting machine.
