Elixir 1.18 adds an :auto_reload config option to IEx. But when I tried it out, it didn’t do quite what I expected.

After seeking clarification, I managed to figure it out. So I’ve written up a short post explaining everything you need to know about this nifty new feature:

We have written a series of 3 articles about distributed applications.

It is written by beginners in the field, and is aimed at beginners. It is not a course on decentralized programming. They tell the story of our journey of discovery into the complex world of distributed applications.

(The articles are in French or English)

Episode 233 of Thinking Elixir. News includes the long-awaited release of Phoenix LiveView 1.0, exciting enhancements in Elixir 1.18 such as built-in JSON support and improved ExUnit testing capabilities, and the unveiling of AWS Aurora DSQL, a serverless distributed PostgreSQL-compatible database service. Lars Wikman joins us to share updates about Nerves, including the latest on Nerves Hub, Nerves Cloud, and his project oswag.org where you can find official Elixir and Nerves T-shirts. All this and more!

A talk by Isaac Yonemoto in which he talked about how Elixir was used at Positron to accelerate the process of developing machine learning hardware. The BEAM VM offered some incredible advantages in servicing ML workloads, and Isaac discussed these advantages from his perspective. Given that the current state of the art tends to use Python, he made specific comparisons to highlight the differences.

In part one of this series, we managed distributed state using GenServers. In this part, we’ll explore deployment and scaling strategies: https://blog.appsignal.com/2024/12/10/distributed-phoenix-deployment-and-scaling.html

Another blog post from the bitcrowd RAG series. This time you’ll find out how you can implement a local RAG system in Elixir.

Episode 232 of Thinking Elixir. News includes Saša Jurić updating his project for “The Soul of Erlang and Elixir” talk with the latest technologies, the release of Phoenix LiveView RC 8 with exciting new features, ErrorTracker v0.5.0’s enhancements for Ash applications, and the introduction of the NX MLX backend for Apple Silicon, offering efficient machine learning on Mac hardware. Plus, a new VS Code plugin called “Refactorex” brings robust refactoring capabilities to Elixir. We also interview Gonzalo Rodriguez about Tower, a vendor-agnostic error tracking and reporting tool in Elixir, discussing its creation, functionality, and how it simplifies error management across various services. And more!

The gettext_llm library allows you to translate all Gettext PO folders/files in your project using any LLM endpoint supported by langchain. The library provides several mix tasks that can be run directly in your Elixir/Phoenix project from the command line (ie. locally on the dev machine) or part of a CI/CD pipeline.

The library provides configurable tone/persona and style. This allows you to “shape” your resulting translations into something that is compatible with your app audience & brand.

I’m thrilled to share YOLO, my first Elixir library, designed to make real-time object detection simple and accessible for Elixir developers. Built around the power of YOLOv8, this library lets you detect objects in images or videos with speed and ease.

Here’s what I’ve worked on:

• Fast detections: Just 38ms per image on a MacBook Air M3 with EXLA.
• Simple API: Load models and detect objects in just two steps.
• Extensibility: Built for YOLOv8, with support for custom models on the way.
• Rust-powered NMS: Optional Rust NIF for blazing-fast post-processing.

Recently, we’ve had an incident with one of our RPC services on production. The root cause was an issue with a PgBouncer instance going down. Although PgBouncer was eventually restored and became operational, our service remained partially functional until the pods were restarted. In this article, I’ll document the root cause of the issue and how we fixed it, effectively answering the question posed in the title.

Instead of evaluating 15 different libraries for each function, Elixir typically offers one or two battle-tested solutions per problem domain: https://hackernoon.com/prevent-decision-paralysis-with-these-battle-tested-elixir-libraries

LiveView v1.0.0 is finally here! The biggest change from 0.20 is that there’s a new way to render data in HEEx: {…} is now available as an alternative to <%= … %>.

In my new post I explain everything you need to know about this new feature, including some subtler details:

I was trying to explain this the other day. So, naturally, I made a video. 😄

How do we coordinate a message that runs through a GenServer’s handle_call/3 and handle_info/2 in a way that makes it seem synchronous from the caller’s perspective?

The secret: GenServer.reply/2

Enhancements in ergonomics enable a more cohesive and developer-friendly approach to invoking live components compared to function components.
