💜 3 day in-person course with Łukasz Pauszek

🗓️16-18 Oct, Berlin (right after Code BEAM Europe)

Dive deep into the inner workings of building applications using OTP behaviours, exploring the proven abstractions necessary for creating back-end, fault-tolerant systems that can run for years and scale to billions of users.

The course includes ample lab time, allowing you to hone your skills and apply theory to practice, with about half of the class dedicated to lab work or coding alongside your instructor.

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.

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.

Episode 215 of Thinking Elixir. News includes a new video by German Velasco explaining quote and unquote in Elixir macros, updates on the Hex.pm “Bob” project for pre-built Elixir and Erlang binaries, Sonic Pi sponsorships and support from Dashbit, the release of ElixirLS v0.23.0, and Google’s recent antitrust ruling. We also cover new developments with the Error Tracker library, Florian Arens’ guide to building a Phoenix HEEx component, and upcoming events at ElixirConf 2024, and more!

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.

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.
