Elixir Brasil Online Meetups
Good morning, everyone!
I’m kicking off a project with a calendar already planned through December 2025. The idea is to host online meetups every first Saturday of the month, focusing on Elixir, the BEAM, and Software Engineering.
This project, titled Elixir Brasil Online Meetups, invites the entire community to actively participate — whether as a listener, a contributor, or even a guest speaker.
Let’s come together to build a rich, inclusive, and collaborative community experience throughout 2025. I’m counting on you to help make this project something truly special!
Turn Old Into New: Moving to Elixir Feature by Feature by Anita Ludermann
Join Anita Ludermann, a seasoned software engineer at Modell Aachen GmbH, as she shares her journey of modernizing legacy systems with Elixir. With over a decade of experience, Anita and her team have successfully migrated their outdated codebase to a modern, maintainable solution, step by step. She’ll dive into the challenges they faced, like bridging old and new systems, shifting to functional programming, and using the strangler fig pattern. As a co-founder of Ladybugs Aachen, Anita is also passionate about fostering community and supporting women in tech. https://www.elixirconf.eu/participants/anita-ludermann/

Embedding external resources in Elixir source files
I wrote about how to embed external resources in your Elixir files so the compiler can track when they change.
The journey of building Benchee as the go-to benchmarking tool in the Elixir & Erlang ecosystem
Tobias Pfeiffer takes us through nearly 9 years of Benchee in his keynote at Code BEAM Stockholm! In this talk, he’ll explore:
1️⃣ The journey of building Benchee as the go-to benchmarking tool in the Elixir & Erlang ecosystem 2️⃣ Key lessons learned about performance on the BEAM, including the impact of GC, tail recursion vs body recursion, and more 3️⃣ Insights into the open-source process, mistakes made, and how collaboration shaped the tool’s success https://codebeamstockholm.com/keynotes/Benchee-9-Years-of-Benchmarking-on-the-BEAM/
Why Tailwind CSS is the perfect fit for Phoenix & LiveView
Get a taste of what you’ll learn at ElixirConf EU 2025 by watching Meks McClure break down why Tailwind CSS is the perfect fit for Phoenix & LiveView—from basics to advanced styling! https://youtu.be/lGfVYDyIY5c?si=vpZ3ByFdBcgSsHqC
Tiger Game with Elixir and Phoenix LiveView
This is my Tiger Game built with Elixir and Phoenix LiveView. With the help of DeepSeek, I was able to develop this application in record time. But the real game-changer wasn’t just AI—it was the powerful process abstractions and WebSockets that Elixir and Phoenix LiveView provide.
I believe it would be difficult to build something like this as quickly in another stack.
Next video: I’ll show how to refine the code generated by DeepSeek, focusing on human maintainability of this legacy. Stay tuned!
Mix task for saving/updating configurable list of Hexdocs packages
LocalHexdocs is a Mix task for easily saving and updating Hexdocs files locally on your machine so you always have the most recent documentation for any Elixir, Erlang, or Gleam packages you might want to view.
Clone this repository, create a /packages subdirectory, then list your desired Hexdocs packages (one per line) in one or more files (named anything you wish) inside this /packages subdirectory, then fetch the lastest Hexdocs for all packages to your local machine with:
mix run local_docs.exs getMinHeap implementation
In this video, we explore how to implement a MinHeap data structure in Elixir, taking advantage of the language’s flexibility to create a generic interface and allowing dynamic switching of implementations during runtime. The main goal is to demonstrate how the combination of facades and benchmarks can be used to measure the performance of different approaches, adapting to the performance needs of the system in real time.
Elixir's Advantage in the Era of AI
Aaron reflects on his experience using Coding Assistants in Elixir repos. And then he tries to predict the future.
Shorthand Package
In this episode we’ll explore Shorthand - a handy package that saves time by providing convenience macros to create or match against maps and keyword lists.
