I just bought a domain to start a podcast about all things Ruby, Rails, the web and all the awesome people building it.
Wish me luck!

Hey @joel.drapper.me! I was watching your Euruko talk on Phlex and noticed the live demo didn’t make it to the video. Is there another version of it showing the demo?

Just bought this! Joe’s work is great and I’m more than happy to support this.
I used to work at a startup where we used Turbolinks native about 8-9 years ago. How I wished a resource like this existed back then!
I think this’ll be huge! Thanks for making this!

If a company says it supports the latest 2 versions of a browser, what does that really mean?
Safari 17-18? Since 9/2023
Chrome 123-124? Since 03/2024
Firefox 132-133? Since 10/2024
That doesn’t seem useful does it?

Google's "Baseline" is a decent way to think about browser support that you *could* use for your own projects, but the crucial thing it doesn't tell you is "is this feature progressive enhanceable?" which changes that math entirely.

Like every good product, the idea for this came from a real problem we had at work; programmatically generating backgrounds for a stories-like feature in an app we worked in.

Putting CSS Anchor Positioning to the test by throwing dropdown menus around 💪
[popover].dropdown {
top: anchor(bottom);
right: anchor(right);
position-try-fallbacks: flip-block,flip-inline;
}
That's it 👆 Keeps the menu tethered to the button
(may as well bring over some hits from the other place)

Back in school it was Logo 🐢 and then MySpace. Then I went to uni to study Music and Audio Engineering and learned about audio+art using Arduino and Processing. I had a short & failed stint learning Objective C to get on the iOS wave before finally landing on Ruby on Rails which was life-changing!
How did you get into web development?

1. The "rails new" equivalent is super nice and interactive.
2. I don't like importing stuff 😂 (Zeitwerk rocks)
3. Scoped styles out of the box is so nice!
4. Auto browser reloading is FAST. We need this so bad in default Rails.

It’s strange by the standards we’re used to. And I like it. Like bitter medicine. I don’t want more but it makes me better.
