💜 A favor to ask: I'm looking to land Elixir consulting work. To help get in front of new faces, I have a "one problem, two weeks, $6,000" offer. Aimed at one nagging thing: a flaky test suite, a stalled upgrade. The debt that falls on the floor. A share or an intro would mean a lot. 🙏 #ElixirLang

The cat is out of the bag: we’re doing badges again for #Goatmire 2026! Each attendee will get a digital badge in their goodie bag, powered by #AtomVM and #ElixirLang. Featuring an ESP32, LCD, keyboard and some fun onboard sensors Join us for Goatmire in Varberg, SE Sept 27th - Oct 3rd to get one!

🚨 Announcing Pushin 🚨 Now officially: I'm announcing Pushin.eu, a git hosting platform built and run entirely in Europe. Think GitHub/GitLab but European, better, and faster. Built with #ElixirLang and #RustLang. peterullrich.com/announcing-p...

Here's a sneak peak into what we'll be building during the @nerves-project.org training 😉. See you all at @elixirconf.bsky.social next week 👋 #ElixirLang #MyElixirStatus #Erlang

Almost done with the last Nerves project for the Elixir Conf training! Excited to see everyone next week! #ElixirLang #MyElixirStatus #Erlang

This seems like suuuuuch a powerful idea, yet I'm struggling to figure out how I'd actually use it. legion.swmansion.com #ElixirLang

🥳🎉Today is the day🎉🥳 @hugobarauna.com, my brother and I are ready to release Elixir for Finance! We've poured all of our knowledge and know how into what we believe is one of the best programming+finance books out there 😍. 👉 financialelixir.dev #ElixirLang #Erlang

Wrapped up another project for the @elixirconf.bsky.social Nerves training next month! It took a little bit of creative programming, but you can now render VegaLite charts on your NSK's EInk display!! Don't forget to sign up, hardware is limited! elixirconf.com/trainings/ha... #ElixirLang #Erlang

Would like to announce THE solution for dynamically composing, delivering and react WhatsApp messages. +

Just published Phoenix 0.12.0! 🎉 Excited for this one because it now supports `aria-label` and `aria-labelledby` Thanks to contributors for making it happen! 🥳 phoenix-test.hexdocs.pm/PhoenixTest....

Love the product and use it daily, and I'm glad to see that the server component is written both in #ElixirLang and #GleamLang (will read the source later this week).

You don't need ten agents. You need two tracks. www.youtube.com/watch?v=EBOT...

Trying something new. I’m turning my two-track agents article into an animated explainer video. Writing a script, syncing with images, animations... It's hard! 😱 Hope to share the result soon.

Instead of running ten agents in parallel, I use only two. And that works really well for me, so I decided to share why and how. tidewave.ai/blog/two-tra...

It’s hard to collaborate with Claude Code on writing. Too much copy/paste. I wanted something like Google Docs for the agentic. So, I used Tidewave to build a local Markdown editor where I can connect Claude Code and we can work together. Would you use this?

Tidewave is the first AI tooling pitch in a while that sounds like it understands the actual job: not just reading code, but running it, querying data, and checking logs. If it works as advertised, that’s a meaningful step up from autocomplete with branding.

I use LLMs to audit my code a few times a week now. Below is the prompt I use most often. It's super simple, runs in less than 30min on a medium codebase, and gives you actionable suggestions for how to improve performance, data integrity, or security in your codebase. #ElixirLang

I'm using @ash-hq.org for the first time and I believe their tagline should be: *Ridiculously powerful* The amount of heavy-lifting they do is absolutely bonkers. All the stuff you don't *want* to care about in a web app is just being taken care of. *Massive* kudos to everyone involved!

Bye bye Claude Code 👋 We had a great time. But it's time to move to Codex. I want to be free to choose the harness that works best for me while paying for my agent provider subscription.

Come to Brazil, and the caipirinhas are on me! #elixirlang #elixir #erlang www.elixirconf.com.br/

We've got a great surprise! 🎉 If you couldn't attend this year, some of the videos are now public. www.youtube.com/playlist?lis... We can't wait to see you at our next events this year: CBL Stockholm, ElixirConf US and Code BEAM & MQ Summit in Haarlem. ✨

📣 The Elixir community is coming to #Chicago: big ideas, great architecture. And so is the DNSimple team. We're proud to be a sponsor of ElixirConf 2026! 🎉 Can't wait to connect with the people building amazing things with #ElixirLang.

Got my first PR merged in OTP! github.com/erlang/otp/p... Found that small doc mistake while preparing my "Erlang Distributed Lessons from Livebook" talk. #ElixirLang

Yay, here's a free new tool for Rocket Validator I've been working on lately: a Color Contrast Checker for WCAG compliance, powered by LiveView and entirely developed using Tidewave. #ElixirLang #a11y #accessibility #color rocketvalidator.com/tools/contra...

Having fun with Nerves Name badge! #ElixirConfEU

Now, once you finish working on a PR, you can ask your agent to: - record a video simulating a user using your app - add subtitles overlay explaining each action - with focused and animated interactions - add voice narration www.youtube.com/watch?v=U4CC...

Beautiful! ❤️ 🧡 💛 💚 💙 💜 🤎 🖤 🤍

I was able to wire up Popcorn to run Elixir and PGlite to run Postgres, both in the browser. This means we can have an interactive and safe sandbox for arbitrary code. Which means a really good experience learning Ecto on a website. I'll publish it soon :) #ElixirLang

The workflow I use to ship production software with AI coding agents. Not 10 agents in parallel. Just 2. One implementing a feature, one prepping the next. Coordinated through Tidewave's task board. I built Elixir Radar's newsletter system in a week this way. www.youtube.com/watch?v=A1_L...

Alright! Introducing Dux: distributed #DuckDB backed dataframes for #elixirlang. cigrainger.com/blog/introdu... v0.3 dropped today and with it, distribution is fully supported and Dux is officially outperforming Explorer. I'm excited to hear what you all think.

José Valim showing how we use Tidewave to build Tidewave 👀

Our paper “Mind the gap: Linking refactorings and code smells in Elixir” has been accepted for publication in the Journal of Software: Evolution and Process. It will soon be open access (thanks to CAPES + Wiley), meaning free and legal access for everyone! #ElixirLang #Refactoring #CodeSmells

Hey #ElixirLang folks! Here's a little something I've been working on. I'd love some early stage feedback. dux.now
