If and when it does are we ready to make the most of it? In this introductory talk Joseph will concentrate on how Property-Based Testing expresses intent, how to conceive of properties, and how this discipline helps to write correct software.

DISCOVERING DISTRIBUTED SYSTEMS IN ELIXIR by Maciej Kaszubowski THIS TALK IN THREE WORDS: Distributed systems Tradeoffs Multi-node TALK LEVEL: Intermediate ABSTRACT Elixir is often advertised as a great platform for building multi-node applications. While there’s some truth in that, there is nothing easy about distributed systems. This talk covers the nice things available to Elixir developers thanks to the Erlang VM. We also learn how these features are actually implemented and what guarantees they give us. With that knowledge, Maciej offers up example problems to be solved and explores possible solutions and their trade-offs. Have you ever wondered how Phoenix Channels or Phoenix Presence actually work? Why there’s so many different solutions? What’s the difference between :global and :pg2 modules? Or whether these “CRDT” things will solve all of your problems with distributed computing? If so, watch and discover the scary and fascinating world of distributed systems. Read the full abstract: http://bit.ly/2OljQ6u --- THE SPEAKER - MACIEJ KASZUBOWSKI Software developer at AppUnite Maciej is a developer at AppUnite where he's been using Elixir for about two years now. Interested in software architecture, distributed systems, data synchronisation and consistency guarantees. Currently writing his Master’s Thesis on CRDTs. Lately, a frequent speaker and a co-organiser of Poznań Elixir meetup. Started to love speaking even more after giving a talk on ElixirConfEU 2018.

While applying proven design principles, the available and growing ecosystem also enabled us to focus on the domain: Travel search and booking are depending on hundreds of requests to (inherently unreliable) 3rd party APIs. How can you leverage our learnings to build a great product?

There are also many applications where MVC is not suitable. In both cases Elixir is a great choice. This talk is a guide for alternative architectures e.g Hexagonal/Onion/Clean. In this talk Peter: Reviews some ideas of designing software. What separation of concerns really means. Discusses how to use the tools we have to organise our code such as mix, umbrellas and releases. Finally asks some questions about what more the Elixir ecosystem needs to reach its potential. Read the full abstract: http://bit.ly/2OpmrfP --- THE SPEAKER - PETER SAXTON Elixir developer at paywithcurl.com Working with Elixir everyday at paywithcurl.com, and loving it. Discovered Elixir after using Python, JavaScript, Ruby and Scala. Before programming was conducting research into quantum optics. Believes that message passing is a great way to think about distributed systems. Nowadays developing Raxx with the goal of extending message passing beyond the BEAM.
