Workshop Registration

Two of Elixir's best teachers step up to get you ready for Goatmire Elixir. Prolific author and professional trainer Bruce Tate teams up with omnipresent community problem solver Benjamin "lostkobrakai" Milde. This duo will give a one-of-a-kind session to get your started with Elixir. 4 hours to get you rolling and ready to take advantage of the other workshops and help you enjoy the conference even more. Corporate-training grade instruction but fun. Requirements: - Programming knowledge, student, hobbyist or professional - Install an Elixir development environment (instructions coming) More details to come.

“There is never enough time to do it right, but there is always enough time to do it over.” ~John W. Bergman Test Driven Development (TDD) is a powerful approach that yields better, less buggy code. So why isn't everyone doing it? In this hands-on workshop, I'll explain what TDD is and why I think it's so good. We'll also try it out for ourselves, using real-life examples. You'll get to see how TDD makes writing great code simpler and gives you a safety net for when you have to make big changes to your code. We'll explore how to plan tests, the role of refactoring in TDD, and the benefits of incremental software design. Working in pairs (or triplets) is actively encouraged. Grab your laptop, a language you're comfortable with, and let's go!

Ever wondered what makes Elixir tick under the hood? In this hands-on introduction we crack open the BEAM and follow the natural path from spawning your first process all the way to building your own GenServer. Along the way you'll get a feel for message passing, stateful processes, and why "let it crash" is a feature, not a bug. By the end, the foundations of concurrent Elixir will feel solid — and you'll know exactly where to go next. Bring a laptop, a taste for concurrency, and an urge to tinker.

In this hands-on workshop, we’ll use Docker to build reproducible environments that behave consistently across development, CI, and production. We’ll focus on the fundamentals that matter in real-world workflows: how to build efficient Docker images, structure your build process, and integrate Docker into CI pipelines. We’ll also explore practical techniques to iterate quickly during development, including using aliases and tooling to streamline your workflow. By the end, you’ll be able to build and run your applications in a consistent, reproducible way, and integrate Docker into your day-to-day development workflow. The examples will use Elixir applications, but the patterns apply across any language or stack.

In this groundbreaking workshop we will have Fairphone 3 smartphones for every participant. You will get an Android phone running Nerves and the session is focused on a shared effort to hack new functionality this Nerves-based phone OS. And learn some stuff along the way. Run by Marc Lainez, who presented on the Nerves Car at Goatmire last year, you'll be in good hands as you explore what we can do with this device. Most IoT devices are lower end hardware with limited peripherals and capabilities. Smartphones are the exact opposite. They contain every capability under the sun and a battery at that. This workshop will be something quite special and in the end you'll have custom device that lets you develop on it in Elixir that we all duly saved from the landfill. If you know how to build stuff with Elixir you know how to do this. You don't need to know about reverse engineering phones or anything. (note: don't bring old phones to convert, developing a new Nerves system for a smartphone takes more time, unless they are a Fairphone 2 or Fairphone 3 in which case, why not :) Requirements: Install an Elixir working environment and the Nerves tooling. Instructions coming.

Managing infrastructure manually doesn’t scale. Defining infrastructure as code allows teams to build, evolve, and operate systems in a consistent, reproducible way. In this hands-on workshop, we’ll use Terraform to define and manage infrastructure through real-world workflows: how to structure projects, manage and reason about state, and safely plan and apply changes. We’ll also explore how Terraform fits into CI pipelines, including how to validate, review, and apply infrastructure changes as part of a collaborative workflow. By the end, you’ll be able to manage infrastructure through code, collaborate on changes, and integrate Terraform into your day-to-day development workflow.

ML/AI is often presented as magic hidden behind frameworks and huge models. In this workshop, we will take the opposite approach: start from first principles and build up the core ideas step by step. We’ll begin with simple models such as linear regression, then move into logits, optimization, and the basic building blocks that make learning possible. Using Elixir, Nx, and Axon, we’ll implement key pieces ourselves so the mechanics of training are not just theoretical, but something you can see and hack on directly. By the end of the session, we will have gone from foundational concepts to a simple neural network capable of classifying images. The workshop is a mix of theory and hands-on coding, with the goal of making neural networks feel understandable, concrete, and buildable rather than mysterious. This workshop is for people who want to understand what “learning” actually means in machine learning, and who enjoy learning by building. Requirements: - Basic programming knowledge - An Elixir development environment installed - Nx and Axon setup instructions will be provided - No prior machine learning background required

Fifty people. Fifty robots. One room. Finding balance is a journey. In this hands-on workshop, you'll assemble a balance bot from a custom carrier board built on the Nerves starter kit, then build a Phoenix app to drive it from your phone. We'll cover hardware assembly, Nerves fundamentals, and building a simple control interface. By the end, your robot will stand on its own two wheels - at least briefly - and you'll leave with the bot and your own repo to continue the journey.
