In this talk I’m going to walk through the changes we need to make for this to happen, and in the process we’ll learn about distribution and clustering and take a dive into the BEAM code server so we can have a lightning fast, easy-to-use, distributed test runner! • See & download slides: https://devon-presentations.herokuapp.com/parallel_ex_unit • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?

This video was recorded at ElixirConf EU 2021 - https://www.elixirconf.eu/ Elixir, WebAssembly, and Rust - The Ultimate Hybrid | KevinHoffman - Author, "Programming WebAssembly with Rust" and "Cloud Native Go" ABSTRACT wasmCloud is a secure, distributed, cloud native actor system runtime that lets developers define and deploy business logic as WebAssembly files (actors). This session walks you through the journey from a pure Rust runtime to a Rust and Elixir/OTP hybrid–learn the what, why, and how of this transition to an even more powerful, robust cloud service. Learn about some of the amazing things we were able to do “for free” that were impossible in the previous architecture. • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?

In this talk we first describe techniques for live analysis of the VM performance, e.g. memory allocation, garbage collection or function call times. We then argue that a controlled termination of a VM, which is in an interesting state, might be a great source of performance information too. We show techniques to inspect the erl_crash.dump file. After this talk you will love your crash dumps more than ever before! • See & download slides: https://drive.google.com/file/d/1HkILzc6tBiccu4hUX_e7gZGxzHqPCs0f/view?usp=sharing • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?

This video was recorded at ElixirConf EU 2021 - https://www.elixirconf.eu/ Creating a scalable intent classifier with Elixir, Python and Tensorflow | Arjan Scherpenisse - Founder at Botsquad ABSTRACT Modern NLP (Natural Language Processing) tasks often build upon large, pre-trained language models like BERT. Neural networks that use these tend to take up a lot of memory, which makes it difficult and costly to scale. In this talk I present the QnA ninja, a classifier service that recognizes text for for example answering FAQs. Elixir is used to coordinate the classification and training of multiple intent classifiers concurrently. It is capable of scaling by using BERT as a feature extractor combined with distributed Elixir to coordinate pools of Python worker processes. • See & download slides: https://drive.google.com/file/d/19uqny3lktCNeSqDVyIgIcoxRLXHPyx-3/view?usp=sharing • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?

Most of them use a dedicated library to instrument your application, which reduces software reusability and interoperability. OpenTelemetry defines a standard way of collecting application traces, metrics, and logs, that is vendor- and language-agnostic. Since OpenTelemetry became stable in early 2021, I’d like to review its Elixir support and share my experience with monitoring Elixir applications at scale. • See & download slides: https://drive.google.com/file/d/1oNUli4gvUmP56UPTa3fvRELi9ahlM3fr/view?usp=sharing • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?

This video was recorded at ElixirConf EU 2021 - https://www.elixirconf.eu/ The pillars of Metaprogramming in Elixir | Adi Iyengar - Senior Software Engineer ABSTRACT Elixir relies quite heavily on metaprogramming. We use metaprogramming features in elixir regularly, sometimes without even knowing. In this talk, I will explain some Elixir constructs which help you better understand how metaprogramming works in Elixir. • See & download slides: https://drive.google.com/file/d/1zN3JKqFbtuvcClmOQgqvuDrmy3mwNLSx/view?usp=sharing • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?

This video was recorded at ElixirConf EU 2021 - https://www.elixirconf.eu/ Debugging Elixir Code - The Tools, The Mindset | Michal Buszkiewicz - CTO & Founder @ Curiosum ABSTRACT In a perfect world, debugging wouldn’t exist. It’s not a perfect world, and we have to deal with bugs and tackle them. Elixir and Erlang have plenty to offer in this area - with tools and approaches that are sometimes little-known and overlooked. We’ll talk about the state-of-art Elixir debugging tools, and how we can utilize them and approach debugging efficiently - as well as point out how the language could improve on this. • See & download slides: https://drive.google.com/file/d/1ViHy-qj67B5XTM4iOKwmcxs4-S-rGBU6/view?usp=drive_open • Follow us on social: Twitter: https://twitter.com/ElixirConfEU LinkedIn: https://www.linkedin.com/company/27159258/ • Looking for a unique learning experience?
