pseudo, adjective: being apparently rather than actually as stated CSS pseudo-classes are like regular classes in that they can be used to select DOM elements. They’re unlike regular classes in that you can’t see them in the HTML. They select elements dynamically, based on their own rules. This is what makes them powerful.

Last time I was in Amsterdam I was 17 and it was a different kind of trip. This time I was speaking at RailsWorld 2025. My first time giving a talk at an event of this magnitude. I’ve given many meetup talks but this is different. Also, the last time I talked in front of a few hundred people was before Covid, and that was in my home town.
