This video was recorded at Code BEAM America 2022 - https://codebeamamerica.com/ Refactoring via the Language Server Protocol | Simon Thompson & Dominik Katkó - Professor at the University of Kent & MSc student at the Technical University of Denmark ABSTRACT Refactoring is the process of improving code without changing what it does, and is typically supported in tools such as Wrangler for Erlang. The Language Server Protocol (LSP) allows tools like this to be integrated in a variety of editors, including VS Code, emacs and vim, and the Erlang Language Server (ELS) provides an integration of Erlang into LSP. After a short introduction to refactoring, Wrangler and Erlang LS, we explain how facilities in Wrangler, including refactorings, input and form-based choices, are incorporated into ELS and LSP, and demo these for a variety of Wrangler refactorings. • Timecodes 00:00 - 01:13 - Intro 01:14 - 05:31 - Refactoring & Wrangler 05:32 - 10:08 - Language Server Protocol 10:09 - 17:11 - Wrangler LS Implementation 17:12 - 26:07 - More Complex Refactorings 26:08 - 32:19 - QnA • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

At this scale, various kinds of data points must be collected, processed and observed to maintain the health of the infrastructure - one of them is network flows. Our infrastructure components export flows at the rate of 2M packets per second. This talk describes a data collection, processing and storage system for network flow data written in Erlang. It gives an overview of the system’s architecture and some of the interesting challenges we faced while scaling this system. OBJECTIVE Share the details about the data processing system we built at LinkedIn using Erlang for collecting and processing high volume and velocity of network flow data AUDIENCE Erlang developers / Observability engineers / Backend engineers • Timecodes 00:00 - 02:02 - Intro and Agenda 02:03 - 07:15 - Intro to InFlow 07:16 - 11:15 - Applications of Flow Data 11:16 - 22:18 - InFlow Collector Architecture 22:19 - 41:22 - InFlow Collector at Scale • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

Whether you’re tracking application metrics, financial price information, or IOT sensor data, having an effective means to store, analyze, and display this can add value to any product. However, having an accessible timeseries database can be a challenge, with many proprietary databases requiring licenses, infrastructure costs and maintenance. TimescaleDB is an open-source alternative that is simply a Postgres extension, a database that many developers are already using. In this talk, we will look at what problems are needed out of a Timeseries database, and how TimescaleDB can help you solve these problems with familiar tools that are easily accessible on the BEAM. OBJECTIVES 1) Teach the audience where they might encounter timeseries data in their product 2) Introduce TimescaleDB, how you can deploy it to your existing Postgres deployment 3) Share ways of leveraging the unique features of timescale DB, including compression, continuous aggregates, and other features to build interesting applications on top of this data platform. AUDIENCE Developers who may have timeseries data in their product, but have no found effective ways to utilize it, or are struggling with scaling timeseries aggregations • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

MongooseIM is Erlang Solutions’ robust, scalable and customisable messaging server, and using it as a “case study”, I want to tell the story of the evolution of a big and old open source project. I’ll start presenting common Erlang design patterns for a server – the supervision trees, the many processes, the NIFs when they are needed, and most importantly, the ways to preserve a big project manageable and continuously evolving. I also want to present the libraries that branched off from MongooseIM. In the evolution of a big project, often times you find pieces of code that are not an integral part of the business logic but actually can be generalised and reused for projects potentially very different from your own. I want to present what we found and how, what we extracted, and what we prepared for other people to reuse. • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

This video was recorded at Code BEAM America 2022 - https://codebeamamerica.com/ seL4 and BEAM: A match made in Erlang | Ihor Kuz - Operating system engineer @ Kry10 & seL4 TSC member ABSTRACT Erlang and Elixir are great languages for programming concurrent and fault-tolerant applications yet they still require BEAM to run them on real-world hardware. BEAM is a complex piece of software that leverages general purpose operating systems to enable concurrent applications to scale to incredible levels. But what if you want to run Erlang or Elixir without an OS? Modern operating systems such as Linux are large and complex and can be the wrong choice to deploy on for embedded applications that prioritize security and robustness. What would it take to run the open-source BEAM implementation in a freestanding environment with no external OS services but still presented a partial POSIX system interface? Would this implementation still allow for useful applications? What are the tradeoffs and what features do we need to give up? This talk tries to answer these questions by presenting a recent project that ported BEAM to a freestanding environment for ARMv7 application processors. OBJECTIVE Explain how the BEAM virtual machine can be run in a minimal self-hosted process environment without a runtime dependency on a large general-purpose operating system and discuss what tradeoffs are associated with this approach and why you would want to do this when seeking better security and robustness. AUDIENCE Embedded systems software developers as well as anyone else interested in understanding or removing various abstraction layers that sit between our high-level software and the physical machines that compute it. • Timecodes 00:00 - 01:29 - Intro 01:30 - 04:41 - Connected Industrial Devices 04:42 - 09:06 - Achieving Security and Resilience 09:07 - 11:26 - seL4: Microkernel 11:27 - 16:25 - seL4: Formal Verification 16:26 - 22:22 - BEAM and seL4: Example 22:23 - 25:27 - BEAM Communication 25:28 - 26:23 - Summary and Future • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

This video was recorded at Code BEAM America 2022 - https://codebeamamerica.com/ Deep dive in Nx Backends | Paulo Valente - Software Engineer ABSTRACT Elixir's Nx library implements its features through a configurable backend structure, in which inputs are dispatched to their respective implementations at runtime. In this talk, we're going to review Nx's Backends and how they play with performance and automatic differentiation. For this, we're going to study how Nx compiles and executes a given code sample and how using defn, Nx's numerical function definitions, can enable Axon (a deep learning library) to work. TALK OBJECTIVES The main objective of this talk is to shed some light in one of the more technical and internal aspects of Elixir's Nx. There are some articles here and there talking about this, but as part of the Nx team I hope to provide some more information about how the library works. This would also be one of the first talks on the subject. TARGET AUDIENCE Although the talk is mainly about an Elixir library, I think all BEAM users which have an interest in machine learning would be interested in it, especially since it's a direct product of the EEF Machine Learning Working Group. It can also be interesting for people which come from an ML background but don't know much about the BEAM • Timecodes 00:00 - 01:10 - Intro & Table of Contents 01:11 - 02:58 - What are the Nx Backends? 02:59 - 04:29 - When to Use Different Backends? 04:30 - 09:25 - Backends vs Numerical Definitions 09:26 - 16:54 - Nx.Defn.Expr Usages 16:55 - 22:29 - To +Inf and Beyond • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?
