Got a few PRs in flight for Credo which cumulatively dropped the runtime from ~33 seconds down to ~9 on our 3500 file #ElixirLang codebase at work. 😁

Yeah it's here: hex.pm/packages/typ...
I've used it pretty extensively so far and it works great for my use case but there might still be some rough edges or missing functionality. I need to push a new release that will update Typst itself to 0.14

Speaking publicly about Elixir stuff (conference talks + podcasts) has gotten me every job I've had since 2020. (And that first one was a 50% pay bump.)
I interview pretty poorly, but having been seen being smart in public got me the foot in the door I needed to prove I could do the work.

Devs who write about their work/company; talk at conferences - lots of companies in the past used to not care much about this and not value it the least.
Feels like the tide is changing: people who do this but are not valued get hunted down by companies who understand this value

BRB, gotta go write a migration for the work DB.
i had a databases class in college in which we were designing a users table and the professor guided us to use (firstname, lastname) as the primary key, and i asked what we'd do if there were two people with the same name, and they said to include the social security number, i think of this a lot

Async tests are great… until shared global state ruins your day.
In this new article, @marpo60.bsky.social breaks down how using ProcessTree gave each test its own isolated environment — solving flakiness and making async tests safe again.

How ProcessTree Saved My Async Tests
This post is about the trap I hit while mocking API calls in Elixir tests, why it happened, and how ProcessTree solved it beautifully.

Quokka is up-and-coming, but not big enough (3.8%). If you're using Credo but not Quokka, you're missing out.

I just figured out how to execute LiveView.JS commands from a JavaScript hook!
This is useful for manipulating the UI directly from your LiveView. For example, here I'm closing a modal after a `handle_event/3` callback succeeded.

I present: playwright_ex
A simple Playwright client for #elixirlang.
Experimental.
Extracted from phoenix_test_playwright.
PRs welcome!
It's not comprehensive, because that's a daunting task (see playwright-elixir).
But it should be easy to add anything that's missing.
