Erlang Fundamentals for Debugging Elixir
This talk by Lorena Mireles was recorded at Code BEAM America 2024
In this talk we will explore the fundamentals behind the magic of some of the debugging tools in Elixir and their benefits to debug borderline conditions and find hard to reproduce bugs in live Erlang systems 🔮🪄
Elixir has a very powerful set of debugging tools not everyone is aware of. They bring the community benefits inherited from the need to debug borderline conditions and find hard to reproduce bugs in live Erlang systems. In this talk, we’ll explore the foundations behind Elixir wrappers like Rexbug, using examples to explain the fundamentals which give us all this magic.
Elixir CI: Testing, Publishing, and Containerization with GitHub Actions
This article is about setting up a CI pipeline for an Elixir application using GitHub Actions. We’ll cover installing dependencies, running tests, and checking code formatting, as well as publishing hex packages and building Docker images as part of the pipeline.

ErrorTracker v0.2.0 has been released
We have just released a new version of ErrorTracker, the Elixir based built-in error tracker. This version adds a few key improvements:
- SQLite 3 compatibility - including a better way to track database schema versions
- Telemetry events - can be used to integrate your own notifications
- UI improvements - more refined styles and UX
- A better test suite - including testing in both RDBMS and different Elixir/Erlang versions in the CI
Take a look at the GitHub repository and the Hex.pm package for the detailed release notes and documentation.

State (Machine) of Enlightenment [Nerves Meetup]
Ben Murphy explores how Erlang OTP’s :gen_statem can outperform GenServer in managing complex, unpredictable systems. Learn how this state-machine-based approach offers cleaner transitions and more powerful directives, simplifying even the toughest system designs.
Bun 1.3.1 released
This new version of the Bun installer fixes a problem with the bun run command and allows you to replace the default Phoenix frontend stack (esbuild + tailwind packages) with just Bun.

Building analytics systems with Elixir | Code BEAM Europe 2023 recording
🎥 https://www.youtube.com/watch?v=1eYIo55dgf0
This is a case study and discussion about state of the art for developing analytical systems with Elixir. Multiple years we are working on Process Mining products with Elixir, using and experimenting with different technologies (Clickhouse, MariaDB column storage, DuckDB, KDB+, Polars). This talk is about problems, design decisions and challenges on the way, like developing in-house ecto-like framework, explaining what you can’t achieve with SQL and why you might look into lower-level technology like Polars & KDB+, ending with trying to show-case some example functionalities on top of Elixir Explorer and comparing them with Python.

ErrorTracker: an Elixir-based built-in error tracking
Announcing ErrorTracker, an Elixir-based built-in error tracking solution.
Features
- Basic, free, built-in error tracking solution. Tracking errors in your application should be a requirement for almost any project and it helps to improve quality and maintenance.
-
Easy to set up. Includes plug-and-play integrations that work automatically such as:
- Plug integration
- Phoenix integration
- Oban integration
- Minimalistic. You just need a relational database to store errors. It can be your application’s database or a separate one.
- Web UI. Includes a LiveView dashboard that allows you to search, manage and resolve recorded errors.
- Extra context. Recorded errors include additional context such as the request path or the LiveView event for the Phoenix integration and the job ID and parameters for the Oban integration. You can also add your additional context.
