The ecosystem is thriving, big companies are picking up our languages, innovation is sprawling, and BEAM-based solutions are getting traction in new domains. But being fragmented, the ecosystem is not as strong as it deserves. There are over 30 languages speaking BEAM, yet only a few can talk to each other. While improvements to Erlang/OTP often trickle down to Elixir and Gleam, the opposite is rarely true. Rewriting everything with Erlang is not an option - we would not rewrite C++ in C either. So what can we do to bring the community together? We want to talk about the challenges we are facing, the future we envision, and some ideas on how we can step into that future. We want to get you inspired to reunite the ecosystem. OBJECTIVES Unite developers working in and on the ecosystem.

Isolated code recovers from faults. Isolated processes can process messages asynchronously with very little coordination. Isolated data means garbage collection is fast and simple. We studied these isolation patterns and asked what would an operating system look like that learned from those lessons and was built to be good at running the BEAM? Could isolation patterns be used to provide deep security that runs from the OS up through the BEAM? The resounding answer to that question is yes! In this keynote, we will present our findings and show you how to build software that uses trustworthy isolation, so that if problems do occur, they cannot spread to the rest of the system. The combination of formal methods, the seL4 Microkernel and the BEAM is the magic formula to build a new operation system for the next generation of software and device. We are very excited to present, for the first time, the Kry10 Secure Platform. • Timecodes 00:00 - 03:21 - Intro 03:22 - 07:54 - IoT: Momentum and Challenges 07:55 - 13:39 - Platform Requirements 13:40 - 17:21 - What's a Microkerner + Formal Methods 17:22 - 27:53 - The Kry10 Platform 27:54 - 30:27 - Summary 30:28 - 43:22 - QnA • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

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?

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?

It gives you practically instant scalability with no need for a large infrastructure team and guaranteed up times, plus the ability to try scaled-down versions of your projects at negligible costs before investing in major infrastructure. So it came as a surprise to me to discover that, after a certain tipping point, cloud computing is actually horrendously cost-ineffective! We’re not talking a few hundred dollars here, we’re talking up to double the IT budget you’d be paying to run the majority of your systems in-house. That doesn’t even include any in-direct cost-savings such as reduced legal fees from simpler regulatory compliance! It turns out that GDPR and similar laws also become surprisingly simple when your customer’s data is physically located on servers you control. Join me for this talk to hear a few examples and a couple of options to move from someone else’s computer to one of yours! OBJECTIVES: To make people aware that the cloud is not the be all and end all of production systems. To give people an idea of when they should start looking at migrating away from the cloud for cost benefits. AUDIENCE: Anyone from dev-ops and sys-admin all the way up to CTO or CIO level • Timecodes 00:00 - 01:57 - Intro & Content 01:58 - 05:59 - Early Cloud Days 06:00 - 10:11 - Whose Cloud is it Anyway? 10:12 - 19:31 - What is Actually Going On? 19:32 - 26:01 - Wrap Up & QnA • 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/ On the way to achieve autonomous node communication in the Elixir ecosystem | Hideki Takase - Associate Professor at The University of Tokyo, Japan ABSTRACT Have you ever felt that finding communication nodes by specifying information such as IP addresses is complicated? RTPS (Real-Time Publish Subscribe) is a communication protocol. The main advantage is that nodes can acquire autonomy in communication. Without setting up any broker, a node can automatically discover communication partners for publication/subscription only by specifying a topic. Note that the use of RTPS is restricted to the area under the NAT server. We are working on R&D about “Rclex,” a client library for ROS 2 platform. This library has directly integrated the feature of RTPS into Elixir. This talk will consider how to bring the power of Rclex into Nerves devices. To find out the current status of Rclex, we will provide a way to realize this purpose. In addition, we will share our latest R&D activity to enable RTPS communication in Elixir/Nerves beyond the NAT server. Once achieved, we can apply RTPS to the wide-area distributed system. • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

You have a list of thousands of IP prefixes, and need a way to compare each incoming conn’s remote_ip to that list. This problem will be used to illustrate several features of Elixir/Erlang. The beginning of the talk will introduce the problem to the audience, and show why the default Elixir data structures are not suitable. Once the radix tree has been covered, we’ll move to the problem of thousands of processes needed to access the same data structure in a short period of time. The talk will cover GenServers, ETS, and the constant pools optimization, and why these are the wrong choice for the problem. Finally, the complete solution will be shown, using persistent_term. OBJECTIVES Introduce the problem of IP address matching Show why the radix tree is a good choice Compare GenServers, ETS, and persistent_term for this probleml • 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/ Tackling Technical Debt at Adobe: A Story which started at Frame.io | Milton Mazzarri - Senior Software Engineer ABSTRACT After the aquisition of Frame.io by Adobe, priorities shifted. From being a startup, we were catapulted to a world of enterprise software development, with the potential of a 10x increase in volumes. Our first priority was tackling technical debt so as to allow us to scale and integrate with their other products. In this talk, we will share some of the technical challenges we faced with a 6 year old Elixir code base and how we dealt with them. From internal code changes, improvements in stability, observability, the database layer, and of course, scalability. These initial improvements allowed us to replace some of the in-house applications with OSS and other Professional packages like Oban Pro+Web, and Broadway. In this talk, you will learn not only how to deal with technical debt, but also how to deal with management, getting them involved in the process and giving you the bandwidth you need to address the issues. OBJECTIVE Show how the team behind Frame.io gained stability, observability and scalability after focusing on paying its technical debt in a six-year-old codebase. And how tackling issues directly in our often neglected RDBMS resulted in immediate benefits.

They have two subsystems, one controlling the plant and the other communicating with a management system on the internet. The latter subsystem, we call SCADA, or Supervisory Control And Data Acquisition. We often use PLCs, or Programmable Logic Controllers, that are industrial computers for the former subsystem. However, PLCs are unsuitable for SCADA because they are too traditional to be a part of a distributed system like SCADA. Therefore we have been trying to use a modern method for it. This time, we produce our own machine running Nerves, an extension of BeagleBone Green. Also, we made a program in Elixir to communicate the management system in the cloud. This presentation will report the system that Elixir uses in an industrial field. Also, we will discuss the issue in the domain that we should consider. OBJECTIVES This presentation will demonstrate that Elixir can be used in industrial applications by showing an actual application of Elixir in a small hydro-power plant. In addition, the presentation will discuss the issues in applying Elixir to further work of Industrial applications. • 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/ OTP Process Abstractions with proc lib | Mitchell Hanberg - Senior Software Engineer at Simplebet ABSTRACT Creating your own generic process abstraction can allow developers to focus on their implementation and not worry about boilerplate. Examples of this exist in OTP with `gen_server`, in Elixir’s Task, and in libraries like Phoenix with Channels. Using `proc_lib`, you can quickly create your own process abstractions that are OTP-compliant: they’re able to be supervised, respond to debugging tools like `sys:get_state/1`, and have their own custom callbacks (`handle_foo`). This is how `gen_server` and `gen_statem` are implemented. In this talk, we’ll explore all the different features that you’ve seen in OTP-compliant processes, what we might want in our own, and hypothesize what it takes to build one. We’ll take this hypothesis and walk through building an abstraction for making custom language servers using the Language Server Protocol. In the end, we’ll see that in just a few lines of code, we can easily build our own OTP-compliant process abstraction and use it to build a process. Talk objectives: Show developers the tools for creating valuable abstractions in their libraries and application code and give them insight into how the builtin tools are written. Target audience: Elixir and Erlang developers looking to increase their understanding and proficiency with OTP. • Timecodes 00:00 - 03:46 - Intro 03:47 - 09:28 - What makes the BEAM special? 09:29 - 11:10 - :gen_server 11:11 - 26:18 - Language Server Protocol: A quick primer 26:19 - 28:28 - Demo.

✨This talk was recorded at Code BEAM America 2022. If you're curious about our upcoming event, check https://codebebeamamerica.com ✨ With a wide range of libraries focused on the machine learning market, such as TensorFlow, NumPy, Pandas, Keras, and others, Python has made a name for itself as one of the main programming languages. In February 2021, José Valim and Sean Moriarity published the first version of Numerical Elixir (Nx), a library for tensor operations written in Elixir. Nx aims to allow the language to be a good choice for GPU-intensive operations. This talk aims to compare Python and Elixir when training convolutional neural networks using MNIST and CIFAR-10 datasets as examples, analyzing development experience, and performance difference.

With a little bit of extra magic, we can create composable, human-readable, expressive, pipeline-able methods that reveal the human meaning behind the data we’re accessing, rather than the implementation details of the DB schema itself. In this talk, I’ll show how to begin decomposing existing queries (and creating new queries) with composable queries, how to organize those queries, and how to make them discoverable. I’ll also show how to accomplish common joins, make use of subqueries, and other common SQL operations.

✨This talk was recorded at Code BEAM America 2022. If you're curious about our upcoming event, check https://codebebeamamerica.com ✨ Raúl Chouza: As BEAM programming languages go, Gleam is a rising star that mantains the same capabilities we love from the platform but adds a slightly different route for constructing programs. Gleam relies on type signatures and a friendly compiler that can very quickly detect some flaws in our logic. In some scenarios it will help with simple casting errors, but in others the type signatures can guide the design of our programs. In this talk I would like to take a tabletop game and explore its implementation in Gleam, showing some of the bits and building blocks of the language plus different approaches of doing abstraction through types. More so, once our core logic is defined we can start thinking on how it can be integrated to the BEAM runtime and how crossing this boundary looks like.

At BYU-Idaho we faced an outdated CS undergraduate curriculum that did not meet Higher Education or industry, and therefore student, needs. In a dramatic and complete rewrite of our CS curriculum, Functional Programming and Erlang became a large part of the solution to our problem.

With barrel you can easily pass, filter and control the data between on-premise or cloud sites using a Peer-To-Peer network built over HTTP and other web technologies like WASM. You can also subscribe to different data stream using using AQMP, MQTT, Websockets, Server-Sent-Events. The data is always under your control and sites even when using our service hosted in different datacenters in our own hardware. With barrel we created and continue to maintain different opensource libraries and projects used by the Erlang Ecosystem: rocksbd binding, hackney, erlang nat, certifi… .. In this talk we will show how to use Barrel and its core opensource foundations in your own projects, why we build it in Erlang and how w’ expect to maintain this opensource product and the different libraries we have built along the years.
