Learn about SAFE for Elixir, a security audit developed with Erlang Solutions, ELTE-Soft and Eötvös Loránd University researchers.

SAFE helps businesses identify and address vulnerabilities in their code. https://www.erlang-solutions.com/webinars/safe-for-elixir-strengthening-security-for-elixir-and-erlang/

Watch the webinar in which team behind the audit will break down common security risks, show how SAFE works, and explain why integrating it into your CI/CD pipeline can make your life easier while keeping your applications secure.

What you’ll learn:

• The biggest security risks in Elixir and Erlang projects (and how to spot them)

• How SAFE makes vulnerability detection more accurate

• How to integrate SAFE into your CI/CD pipeline for automated security checks

• Why secure coding isn’t just about avoiding hacks. It also helps prevent downtime, financial loss, and compliance headaches

Why I Looked Beyond Ruby

For years, Ruby was my go-to language for building everything from small prototypes to full-fledged production apps. I fell in love with its elegance and expressiveness and how Ruby on Rails could turn an idea into a working web app in record time. The community—with its focus on kindness and collaboration—only deepened my appreciation. In short, Ruby felt like home.

But as my projects grew in complexity, I started running into bottlenecks. I had apps requiring real-time features, massive concurrency, and high availability. Scaling them with Ruby often meant juggling multiple processes, external services, or creative threading approaches—all of which worked but never felt truly seamless. That’s when I stumbled upon Elixir.

At first glance, Elixir’s syntax reminded me of Ruby. It looked approachable and developer-friendly. But beneath the surface lies a fundamentally different philosophy, heavily influenced by Erlang’s functional model and the concurrency power of the BEAM. Moving from Ruby’s object-oriented approach to Elixir’s functional core was eye-opening. Here’s how I made that transition and why I think it’s worth considering if you’re a fellow Rubyist.

The summary is if you’re using Phoenix, you are most likely not affected. If you are using Nerves with SSH in production, you may be vulnerable. The Nerves team is aware of this issue and they are actively working on a solution so people can easily update.

Nothing too big, pre_check: :all_same is great when benchmarking alternative implementations of deterministic functions!

Otherwise, some fixes for compatibility with OTP 28 and Windows 11 (or in general more resilient system gathering).
