Hi, friends! In the past 6 months @dashbit helped fund a part-time contributor for Numerical Elixir through @TheErlef. We're nearing Nx 1.0 and are looking to extend the funding! If you or your company use Nx in production, please consider contributing! every.org/erlang-ecosyst…

@flydotio I'm currently developing a cloud hosting course for software engineering apprentices and would love to use Fly.io for a part of the course. Do you have some kind of education plan that we could use for that?

Scaling Security from Zero by @maennchen_ CISO of our Foundation! Learn how a Small OSS Ecosystem Jumped Into the Deep End! Jonatan talk at Code & Compliance is now live 👇youtube.com/watch?v=jl89J0…

Elixir conference in Málaga this April. I'm looking to connect with local companies or teams using (or interested in) Elixir/OTP to host meetups, workshops, or tutorials around the event. If you know anyone in Málaga, please reach out or tag them. =)

Today we celebrate another year of the Erlang Ecosystem Foundation 🎂 What started as a community effort keeps growing thanks to the people who contribute, support, and believe in the BEAM ecosystem every day. Thank you for being part of this journey!

EEF at GOTMIRE Elixir! Check out two great talks from members of our community: 🤝Desirable Shores by Dan Janowski Dan explores the potential of the BEAM ecosystem and what it takes to ensure its long-term health and sustainability. 👉 goatmire.bold.video/v/mex6e 🔐 From Freakout to Fix: Navigating a Security Disaster by @maennchen_ Jonatan walks through how to handle security incidents, report vulnerabilities through official channels (like the CVE system), and bring clarity to those first chaotic hours. 👉 goatmire.bold.video/v/w5mvw

Can Erlang run on QNX? Turns out: yes ✅ In this article, @maennchen_ explores what it takes to port Erlang/OTP to QNX. A great example of curiosity turning into concrete results. 🧾erlef.org/blog/eef/otp-q…

Today we celebrate 15 years since Elixir's first commit. To mark the occasion, we shipped an early release candidate for Elixir v1.20 which has TYPE INFERENCE FOR ALL CONSTRUCTS.🎉 In the latest article, I break down the next ~15 weeks and the challenges for the next ~15 months.

Did you know ORT supports Gleam? Learn how a structured inventory of the components can help you monitor your project's dependencies, its licences and vulnerabilities and how to set it up for Gleam! gleam.run/documentation/…

Hey Elixir friends! :) Great news for Hologram: the Erlang Ecosystem Foundation has awarded a stipend to support key development milestones! I’m deeply grateful to the EEF 🙏 for their support of the project vision. Read more about what this means for Hologram and learn about the EEF’s mission: hologram.page/blog/hologram-… #Hologram #Elixir #ElixirLang #BEAM #WebDev

We (@duboc_guillaume and I) wrote an article about the data-structures that power Elixir's type system and some of the optimizations that went into Elixir v1.19! elixir-lang.org/blog/2025/12/0… Kudos to @heyfresha and tidewave.ai for sponsoring the type system work!

I really like what Hologram is building, there’s a lot of potential there to take it further. If you haven’t yet, consider sponsoring. I just did myself. Feels like one of those projects where a bit of support now could have a big impact later. x.com/Bart_Blast/sta…

Hi Elixir friends, After 3 years building Hologram full-time (transpiles pure Elixir to JS, bringing it to the browser), I'm at a crossroads. Working 60+ hr weeks balancing contracts & dev isn't sustainable. Where we are & how you can help: hologram.page/blog/seeking-s… Even sharing helps 💜 #Hologram #Elixir #ElixirLang #BEAM #WebDev

The Erlang Ecosystem Foundation CNA now publishes vulnerability data directly to OSV.dev . No more relying solely on CVE→OSV conversion. This update means faster, cleaner, and higher-quality security data for the BEAM ecosystem — including Erlang, Elixir, Gleam, and Hex.pm. We’ve also expanded our scope to include: @NervesProject @OpenRiak The EEF CNA (cna.erlef.org) will handle vulnerability disclosures for these projects, going forward and strengthening coordinated security across the BEAM ecosystem. All part of our ongoing ÆGIS Initiative: security.erlef.org/aegis

My wife pulled a classic move and got me a cake 😂 What a gal!

Elixir v1.19 released: enhanced type checking, broader type inference, and up to 4x faster compilation for large projects! elixir-lang.org/blog/2025/10/1… A huge thank you to Fresha, Starfish*, and Dashbit for sponsoring the type system, plus @CNRS and @Remote for making it possible.

💜 @elixirlang v1.19 is the first release with OpenChain certification — bringing more transparency and trust to the BEAM ecosystem. Big thanks to @maennchen_ and our sponsor Herrmann Ultraschall for making this milestone possible! 👏 🔗 elixir-lang.org/blog/2025/02/2… #MyElixirStatus
