👨‍💻 Posted some follow-up observations about phoenix_test performance. #ElixirLang TL;DR: Yes, it can be slower (because it is doing more helpful work), but `async: true` should be your first target if you're having trouble with test wall-clock time -- always. forum.elixirforum.com/t/one-pipe-o...

Could someone take Fluffy for a walk? fluffy.hexdocs.pm Playwright-grounded feature tests for phoenix. Composable locators, actionability checks, browser conformance. Migrating a PhoenixTest base should be smooth sailing via Agent. Worth switching? Eliminates workarounds? Performant? #elixirlang

www.motedis.com/de/Heimwerken Cool. DIY kit configuration for aluminum profiles. Connected to a store. The accessories on Motedis seem to be well priced. While price for aluminum profiles are average - can definitely get cheaper elsewhere.

If you’re running #Phoenix Channels (or LiveView) and have the LongPoll option enabled in your endpoint (default since 1.7.11), it’s time to do an update: github.com/phoenixframe... Thank you @peterullrich.com for finding and disclosing this issue!

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! 🥳 hexdocs.pm/phoenix_test... 📚 Changelog: hexdocs.pm/phoenix_test... #ElixirLang

## 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. --- codex: PORT=4$((RANDOM%900+100)) mix test #elixirlang

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. #elixirlang

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.”

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) #elixirlang

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).

easel-demo.fly.dev/clock This is cool. Takes me back to canvas (turtle) based computer graphics in high school days. #elixirlang

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 www.theregister.com/2026/02/16/s...

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

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
