I also have to thank: literally last week I received a PR for Playwright.reload_page. Perfect timing for the update.
I've released a compatible version phoenix_test_playwright v0.13.0.
PhoenixTest v0.10.0 is released! It's got a lot of things, and (I think) none from me!
A huge thanks for all who contributed! 🥳

Wow. Tax payer money being put to valuable work I'd say!
Not what I usually expect from our German authorities, at least when it comes to tech 😇.
## You're not alone
Other agents may be running (beans in-progress).
Pick next bean that won't lead to edit conflicts.
Ignore other changes in git - commit your changes only.
Run tests with random `PORT=4xxx` env var.

The more I'm leaning into AI in everyday coding work, the more I'm enjoying typespecs.
Goes to show that the Elixir type system WIP is right on time.

AshAdmin 1.0rc is out, with a complete UI overhaul, a rework of our markdown/json editor to code mirror, and features for more convenient relationship management and multitenancy drop-down/typeahead 🎉 #AshFramework #ElixirLang
“Helsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”
Cerberus - Phoenix Testing library?!
Exploring
1. Synergy effect of vertical integration: browser driver doubles as HTML spec oracle for live/static driver tests.
2. Webdriver BiDi instead of playwright (more like cuprite)

I agree for my regular coding.
Code output is not the bottleneck.
Planning, code review, QA are.
On the other hand: spikes, prototypes, experiments. Exploring ideas that you otherwise wouldn't have the time for.
My value add: Deciding which experiments to run in the first place. Steering them.
Agent assisted dev is even addictive (think: hard drugs) than regular coding already was.
Imagine the worldwide immediate cold withdrawal symptoms (provider outage, steep price increase).

This is cool. Takes me back to canvas (turtle) based computer graphics in high school days.

How about this gist.github.com/ftes/a6a7896...
Youtube transcript. Processed with Claude.
Take a prop.
Represent it as a CSS variable.
Now you have a responsive prop.
You read my mind. I was thinking the exact same thing.
I still have a lot to digest. So many good ideas

So the blessed workaround seems to be adding `only: [:dev, :test]` for test only deps like phoenix_test et al.
Maybe it's just me - but since I haven't found a good solution:}

Apparently, there is a fancy word to describe why you can tell AI had a hand in writing some copy (the feeling of what you imagine chewing sand would taste like): semantic ablation

What a great idea!
Rewrote ultimate.ftes.de from JS to Elixir 🎸 It's a free tool to convert music chordsheets (UltimateGuitar → ChordPro, LaTeX, etc.).
Ported ChordsheetJS to Elixir with Claude Code — surprisingly few manual interventions needed. Now on Phoenix and finally motivated to build new features! #elixirlang
Seems like Tidewave can't access test deps, e.g. phoenix_test docs.
Because it's running in dev env.
Or is it just me?

Playwright remote server support (websocket) for phoenix_test_playwright 🥳
Looking for early feedback — especially around CI setups.

step/3 macro automatically links playwright trice to source code
phoenix_test_playwright 0.10.1 released 🥳
Small macro, big effect 🪄:
step/3 groups trace actions and AUTOMATICALLY links to source code line
Big thanks to @nathanl for adding this!

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.
