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

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.

OpenAI aren't talking about it yet, but it turns out they've adopted Anthropic's brilliant "skills" mechanism in a big way Skills are now live in both ChatGPT and their Codex CLI tool, I wrote up some detailed notes on how they work so far here: simonwillison.net/2025/Dec/12/...

This is SO good 🤣

🎉 phoenix_test_playwright 0.10.0-rc.0 released Breaking changes - if you are reaching beyond the PhoenixTest API into internals. Upside: Browser pooling by default. Well documented, consistent PlaywrightEx API for advanced use cases. Early adopters ftw! hexdocs.pm/phoenix_test... #elixirlang

🎉 playwright_ex 0.2 released Focus: documentation and consistency Added docs and typespecs Ensured API consistency, especially 'Channel' modules (browser, frame, ...) #elixirlang hexdocs.pm/playwright_ex/

Hey Elixir friends! :) We need help completing Elixir's browser runtime by porting some Erlang functions to JavaScript. No Erlang knowledge required. Each function unlocks multiple Elixir stdlib functions! More here: hologram.page/blog/elixir-... #Hologram #Elixir #ElixirLang #BEAM #WebDev

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. hexdocs.pm/playwright_ex/

Refactored: Converted PhoenixTest.Playwright.Connection from GenServer to :gen_statem. So much more expressive for this use case. Thanks @Coby Benveniste for the inspiraton at #codebeam. Even though this isn't AI related. github.com/ftes/phoenix... #elixirlang

Call for feedback: phoenix_test_plawright browser pooling Please run locally & in CI. Useful? Stable? Configurable to your needs? github.com/ftes/phoenix... #elixirlang

Surprising ⚡️: Performance of phoenix_test_playwright already pretty good. Compared to official javascript client. Many tests: browser re-use (experimental) brings slight boost. Unclear if worth the complexity. Do you need it? github.com/ftes/phoenix... #elixirlang

phoenix_test 💆 #elixirlang

Any hints on how to implement resource sharing in ExUnit tests? For phoenix_test_playwright, I want shared browser instances. Browser pool, each test module has to wait for available browser in `setup_all`. github.com/ftes/phoenix... Have you seen/implemented something similar before? #elixirlang

Sharing this with a big recommendation. You'll have a hard time finding someone as knowledgeable as @hauleth.dev

phoenix_test_playwright user base has grown to 50% of phoenix_test (judging by number of downloads in past 7 days). Surprises: 1. High number of users. Metric skewed by few power users? 2. Low support effort. Lib is 90% undocumented playwright internals. Playwright js frequently updated. #elixirlang

LiveView colocated hooks: Skip for now due to lack of tooling support? 1. Code highlighting 2. JS Intellisense (language server features) 3. Formatting 4. Unit testing Any thoughts? Some of mine in thread 👇 #elixirlang

Can ExUnit.CaseTemplate `setup` order be influenced? I'd like my CaseTemplate `setup` callback to receive context values from my use-ing Test `setup` callback. Use case: Override Playwright browser options when opening new page. github.com/ftes/phoenix... #elixirlang

Common phoenix pitfalls when upgrading to LiveView 1.1 Tests may break in several ways. - HTML boolean attrs like 'checked' rendered differently - stricter CSS selectors due to lazy_html - phoenix_test needs fix #45 (unreleased) #elixirlang

"Now you can use any [Tailwind combobox] in any project you're working on — no JavaScript framework required." tailwindcss.com/plus/ui-bloc... This is going to make LiveView even more fun. I guess this makes waiting for vanilla-js headlessui obsolete. #elixirlang
