OMG, latest version of Hex (`mix local.hex --force`) prints out CVEs that affect your packages any time you run `mix deps.get` 🤩 #ElixirLang

mix deps.get output, showing Earmark 1.4.48 marked as "RETIRED!" and "VULNERABLE!" due to CVE-2026-48591, "Stored XSS via unescaped HTML attribute values in earmark"

> Also, how are you integrating TDD into these agent workflows? I've been mostly using GitHub SpecKit with a guiding principle that all production code must be TDD, along with a `SKILL.md` that teaches my approach to testing. github.com/github/spec-...

My early praise for the book captures my thoughts:

Joe has given Elixir developers the toolkit we didn’t know we needed. This isn’t abstract functional programming theory; it’s the practical foundation that transforms how you solve complex problems and how your team thinks about solutions together. Read this book, then share it with your team. You’ll wonder how you built systems without it.

Been playing with how AI agents can run their own #phoenix workspaces without tripping over ports or DBs. Ended up using Conductor to spin up isolated dev environments — fast, clean, and super handy when you’ve got multiple agents working in parallel. nicholasjhenry.medium.com/building-iso...

I 💜 this passage from @jkwa.bsky.social buff.ly/xIVq6gW "... understanding doesn’t parallelize, and complexity doesn’t distribute. Each new contributor must climb the same tangled mess... even more time is spent coordinating, clarifying, and patching over mismatches in mental models." #elixirlang

I just finished putting together interactive Livebook notebooks for every chapter of Advanced Functional Programming with Elixir. You can now run all the examples in your browser. Or like me, spin them up locally with Docker: www.joekoski.com/blog/2025/09... #elixirlang hashtag#AFPElixir

Livebook Examples from Advanced Functional Programming with Elixir

It feels a bit impolite to ask readers to download code and type mix commands just to run the examples. We have better tools now.

Explanation: Prior to #ElixirLang 1.19, it was deemed sufficient to compile deps one at a time (compile Phoenix, then LiveView, then Postgrex, then Ecto, etc.), because each individual compilation would be parallelized across all cores. However... 🧵

And that's a wrap! That was a really inspiring @elixirconf.bsky.social during the most disruptive time in our industry. Thank you to everyone who discussed the talk with me afterwards. It's really helpful and rewarding to know what the audience learned. See you in Chicago! #elixirconf #elixir

Really enjoyed @nicholasjhenry.github.io’s talk on validating business rules in Ecto. It had never occurred to me that we should validate some of our association rules in the context, not the schema’s changeset function, but I’m convinced!

My #elixirconf 2024 talk has been published! "Beyond Mocks: Messing with Our Preconceptions of Testing" I discuss the challenges of using test mocks and how they can lead to unreliable tests. I introduce the Nullable pattern from James Shore applied to testing with external dependencies in Elixir.
