Joseph Koski@jkwa.bsky.social · 9mo agoA new post in my series on the Ash Framework. This one explores the underlying mechanics of Ash validation and where Funx can help when checks need more structure or concurrency. www.joekoski.com/blog/2025/11... #elixirlang @pragprog.com
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...
Building Isolated Phoenix Workspaces for AI Agents with Conductor
I’ve been experimenting with agentic coding — letting AI agents handle multiple tasks in parallel across my codebase. The promise is…

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
Advanced Functional Programming with Elixir
Use advanced functional programming principles, practical domain-driven design techniques, and production-ready Elixir code to build scalable, complex systems from simple, reusable components.

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... 🧵

Bot detection goes way beyond user agents TLS handshake to JavaScript execution tracking @tylerayoung.com explores the cat-and-mouse game of web scraping vs bot detection. #ElixirConfUS
Web scraping issues presented from the perspectives of both the scraper and the server operator by @tylerayoung.com at @elixirconf.bsky.social
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!
I'll be presenting at @elixirconf.bsky.social next week on how to apply Business Rule Thinking with Ecto. If you want to learn how to discover and implement business rules in rich domains, this might be a talk for you. elixirconf.com/talks/mise-e... See you there! #ElixirLang #ElixirConf
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.
