What does it mean to have a “real-time” web application? What communication layers can be used (WebSocket, SSE) and how are they used in real-time apps? How does a JavaScript client connect to the server? How does the Elixir server work, and what makes it great for real-time apps? This talk includes snippets of much of the code that powers Channels (and also LiveView), so you can see how it works first-hand. --- THE SPEAKER - Steve Bussey Steve is a software architect based in Atlanta, GA. He loves building software, from frontend applications powered by vanilla JS / React, to server applications powered by Elixir or Ruby. He also leaves teaching and empowering others to find their success in the software industry. Steve is the author of "Real-Time Phoenix: Build Highly Scalable Systems with Channels" by Pragmatic Bookshelf. He believes that real-time applications can offer important user experience improvements and enjoys writing about it. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU

Come learn how property tests can thoroughly test a problem space and make bulletproof software. We’ll look at properties pulled from the Oban background job processor. Some examples we’ll explore: Proving a CRON parser Checking concurrent uniqueness Transitioning between migrations Proving system reliability You’ll leave armed with the ability to recognise situations where properties are more effective than example based tests. --- THE SPEAKER - Parker Selbert Parker is a partner in Søren, a tiny husband and wife consultancy based outside of Chicago. He is an avid open source contributor with particular appreciation for expressiveness and elegance. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU

More great virtual tech conferences - https://codesync.global --- Scenic Now and Looking Ahead by Boyd Multerer ABSTRACT Scenic is a deep UI platorm built in Elixir and intended for machines and situations where a webserver is not appropriate. 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.

This video was recorded at ElixirConf EU Virtual 2020 - https://www.elixirconf.eu/ More great virtual tech conferences - https://codesync.global --- Membrane Framework - the true story of handling multimedia in Elixir by Marcin Lewandowski ABSTRACT Media processing has never been a piece of cake - a large amount of data, tons of different formats, protocols and standards, growing latency and quality requirements. In this talk, we’ll introduce you to the world of media streaming via Membrane Framework - our solution for dealing with multimedia without pain. The framework provides a set of so-called elements, which are composable blocks implementing different multimedia processing operations. The talk will be based on the real use cases of the framework and will explain - what are use cases for such a framework - what are the benefits of using such a framework in comparison to other solutions, - what is the roadmap for the framework, especially in terms of supporting WebRTC. --- THE SPEAKER - Marcin Lewandowski He founded his first IT company when he was still in high school. A graduate of Human-Computer Interaction at Jagiellonian University in Poland. He was bouncing between media and IT industries for quite a while. Founded a cult local FM radio station, then RadioKit, a SaaS startup aiming at building software for the media industry and then smoothly migrated into multimedia. Currently a partner at Software Mansion - a fast-growing software agency serving mostly US startups. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU

This talk proposes to explain what is a type system, why attempts to type strictly Erlang have failed and how the theory of Session Types might prove to be a way to achieve correctness in environments like Erlang's. --- THE SPEAKER - Charlotte Lorelei De Oliveira Charlotte asks too many “whys” and “hows”, this got them to become someone who thinks too much on how to improve things for everybody. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU
