✨This talk was recorded at ElixirConf EU in April 2024. If you're curious about our upcoming event, check https://elixirconf.eu ✨ For the last two years, I've been working with one of the larger energy companies in Germany. As more renewable energy becomes available and the energy topology grows, it becomes harder to track in the enormous energy network where there might be too much or too little energy flowing. We are building an Elixir system to find these problem spots and stop them before they happen. We've been able to work inside a monorepo for years because OTP features have made it incredibly simple to model our complex infrastructure in Supervision Trees and Processes. Testing has been, hands down, the most complex part of using Processes and OTP in Elixir. Whether it's a polling server, an in-memory repo, or trying to do mocks the right way, there are many gotchas and head-scratchers along the way. If you've ever tried to test anything Process-related and scratched your head thinking ""WAT?"", you will find your answers in this talk.

This is often IoT devices, but covers other situations as well. In the past year, Boyd has worked on a LOT of code, which is related to, but not directly in Scenic. In this talk he will discuss the current state of Scenic, where it is going and why and explain what to expect in the future. --- THE SPEAKER - Boyd Multerer Boyd’s near 30-year career spans the range of software projects, from desktop publishing, to web servers, to game consoles, to low-level operating systems. For the past four years, he has been independently exploring and building a full stack for Connected Devices that heavily leverages the BEAM. Previously, Boyd spent 18 years at Microsoft running engineering for things such as Xbox Live, XNA (game developer program), and everything OS for Xbox One. This work includes large scaled-out datacenter services, VMs, and the layout of the hypervisor/kernel. His most recent release is the open-source Scenic libraries, which is a functional UI stack built on the BEAM. Its primary goal is for use in connected devices, but it is already being used for desktop apps and more. His current work takes the foundation laid with Scenic and is attempting to answer deeper questions about the future of client-side operating systems. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU

In this talk, we’ll explore how functional programming, tests and hexagonal architecture can perform great together in order to support a maintainable codebase for hundreds of engineers and services. Diving deeper on how we can levarage hexagonal architecture with dependency rejection in order to decouple decisions from effects, resulting in a code that is easier to reason, compose and test. The codebase is not the only one that take advantages from that, but also the developers. It helps everyone feels more comfortable and engaged about maintaining good practices. This is already proven to work really well at Nubank, which is considered the best bank in Brazil according to Forbes. --- THE SPEAKER - Carolina Pascale Campos Carolina is always exploring new paths and looking for new perspectives for solving problems. As a computer scientist working at Nubank, she loves to deal with distributed systems challenges and code in ((clojure)). She believes that everyone is responsible for making the tech environment safer and diverse. Pasta maker, coffee enthusiast and book lover. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU
