I was shocked by the hex.pm redesign for a moment, but I think I like it. One problem though: new packages are being released so fast now that making the new package list even smaller means I'm going to miss some - it needs a longer list somewhere. #elixirLang

One Weird Trick to avoid getting pwned by these zero-days that depend on you grabbing a freshly compromised OSS package: (Note: requires you to use a lockfile everywhere. You're using a lockfile everywhere, right?)

The work chat now that Claude is tightening their usage limits

The v0.1 release of Expert (the new, official #ElixirLang LSP) is now final! 🎉 The best Elixir LSP experience keeps getting better. 😎 Tremendous thanks to all the contributors, and to Jump for sponsoring @katafrakt.bsky.social to work on this full-time. 🙏 github.com/elixir-lang/...

Wanna find garbage tests in your #ElixirLang codebase? I'm working on a Credo check that will flag any test that fails to exercise production code. Stuff like: test "to_string works" do assert to_string(:user) == "user" end (That's a real example I found in our ~20k test codebase!)

If you're using the #ElixirLang NodeJS package, be advised there's an information disclosure security vulnerability (CVE-2026-33872). It'd be quite difficult for an attacker to intentionally exploit, but fairly easy to accidentally trigger yourself. Update to 3.1.4 ASAP. github.com/revelrylabs/...

AshTypescript 0.16.0 is finally out, with a long-awaited feature: Typed Channels 🎉 Clients can now subscribe to any broadcasted changes from your ash resources, with auto-generated and ready to use Typescript ofc 😎 Read more here: hexdocs.pm/ash_typescri... #Elixir #Ash #AshFramework #Typescript

Boy, thank goodness we have LLM generated tests for this code, otherwise we'd have no tests at all!

One of the greatest joys at work is having been involved in hiring somebody who, 3 months on, has proven to be an absolute rockstar. 😌

Popcorn (the project to run #ElixirLang in the browser) just released v0.2, which makes progress toward running LiveView *locally* in the browser. Wild. I'm already dreaming about what I could do with this. github.com/software-man...

I like this a lot. The MacBook Neo as the ideal computer for sparking kids' curiosity. samhenri.gold/blog/2026031...

Informal poll: which topic would you most like to see an #ElixirConf talk about? 1. How I self-hosted my indie SaaS app 2. Tools and practices for hyperscaling #ElixirLang teams, based on my work at Jump (we grew from 4 to 50 devs my first year there) 3. You already know what a monad is 4. CPU Perf

@k-cross.github.io Do you have any insight into what happened to the dropbox/esaml GitHub repo? It's either gone private or disappeared. 🤔

Apple Vision Pro is Getting the 'World's Most Advanced Flight Simulator'

At work, we were seeing frequent full recompiles of our #ElixirLang app (both the deps and our code!). Turns out it was because Claude Code was using the globally-installed Elixir rather than the one installed by Mise. I wrote about the fix here: tylerayoung.com/2026/03/11/e...

When it comes to AI agents / AI tooling + coding, I hear an awful lot of talk about: Efficiency Iteration speed / PR output rate / lines of codes produced I hear zero mentions about: Quality Customer obsession This will bite back, and it probably already is...

The call for talks for #ElixirConf Chicago (September 10-11) is out! Now to put together some proposals... elixirconf.com #ElixirLang

OpenAI published a repo to orchestrate AI agents built primarily with Elixir (96.1%): github.com/openai/symph... #elixirlang

News includes Expert LSP releasing its first RC, Elixir v1.20 compile time improvements up to 20% faster, #Livebook Desktop moving to Tauri with #Linux support, a new erlang-python library for ML/AI integration, and more! @elixir-lang.org #ElixirLang #AI #ML www.youtube.com/watch?v=Ed83...

This is a huge milestone. At Jump, we’ve had @katafrakt.bsky.social working full time getting Expert dialed in for our large codebase. The stability and reliability are now hands down the best #ElixirLang LSP experience I’ve had, and we’re not done yet. Congrats to all the contributors. 🥂

phoenix_test_playwright v0.12.0 released 🥳 Shorthand to eval JS in browser, assert_path fixes for LiveView navigations, and more. Also ships with usage-rules.md for LLM coding agents. 🤖 #elixirlang

I learned recently (h/t @josevalim.bsky.social 😄) that you can totally omit the result line in an #ElixirLang doctest. This can be useful for pattern matching, like: iex> some_thing = MyFactory.create_thing() ...> {:ok, "https://myapp.com/path?" <> _} = ...> MyModule.compute_path(some_thing)

Does anybody have experience using GitHub-hosted dev containers ("codespaces") for #ElixirLang dev? I *really* want to empower our designers to work on LiveView component HTML/CSS directly (they're already comfortable with those), but getting them a local dev setup is a huge blocker.

Checks out. Some related research - "employees worked at a faster pace, took on a broader scope of tasks, and extended work into more hours of the day, often without being asked to do so" "...leading to workload creep, cognitive fatigue, burnout, and weakened decision-making" hbr.org/2026/02/ai-d...

Quokka is always the first dependency I add to every new project. Such a great tool! And no more “oh my editor formatted it differently, sorry” or “damn I forgot to sort my aliases and now my CI failed”. Brilliant

There’s a new release of Quokka, and it’s a big one. Lots of both new and improved rewrites to automatically make your codebase nicer. 💜 github.com/emkguts/quok...

Anybody have contacts at PagerDuty? I’d love to ask them about their usage of #ElixirLang. They had a blog post in 2020 about it, but I can’t find anything they’ve written since then.

Loved this talk from Mitch Hanberg about the origin story and architecture of the new #ElixirLang Expert LSP. youtu.be/2vIw2fb9DxA

This person made a production management tool for his spouse's bakery in #ElixirLang + Ash + LiveView. It's super valuable to have an codebase like this be open source for people trying to get into that tech stack. 💜 github.com/puemos/craft...

For even more fun, you can capture the struct module 😁 def add_one_hour(%date_or_time{} = value) when date_or_time in [DateTime, NaiveDateTime, Time] do ... end

@june.bash.pizza I dig the song. A little Vangelis, a little hip hop, a little Mass Effect soundtrack. 🔥

Hold the phone. Am I the only one who didn't know (or likely forgot) that you can press opt+shift when pressing the volume keys on a Mac to switch to 1/4 increments? Life. Changed.

I like this setting for VS Code from Ben Frain. JUST show the vertical line for the current indentation, not all of them ``` "workbench.colorCustomizations": { "editorIndentGuide.background1": "#00000001", "editorIndentGuide.activeBackground1": "#ff9900" } ``` benfrain.com/vs-code-high...

TIL Oban's unique job period uses fixed time windows, not sliding windows. A job with unique: [period: {7, :days}] can still allow duplicates 2 days apart if they fall into different buckets. If you need sliding windows, use a custom query. ftes.de/articles/202... #elixirlang #oban
