Super happy that @paolino accepted our invite to keynote Tropical on Rails 2027!

He's one of the people doing the most to make Ruby and Rails relevant for AI. At Linkana we've already adopted ArchSpec, and we're running Solid Queue fiber workers thanks to his work.

@obie has had a huge impact on my path as a Rubyist. I read countless editions of Rails Way to keep up with @rails
He was also one of the first rubyists I saw recognize the potential of AI, and now he's coming to @tropicalonrails to talk about it with Impatient Programming

[Tropical on Rails @tropicalonrails]

[ENG] 🚀 Keynote announcement! @obie is coming to Tropical on Rails 2027!
💎 Serial entrepreneur, author of The Rails Way and one of the best-known names in the Ruby community. His new project is Impatient Programming: Extreme Programming revisited for teams where coding agents write most of the code. He lives by Larry Wall's three virtues of a programmer, laziness, impatience and hubris, and that's where the name Impatient Programming comes from.

Ele vive as três virtudes do programador segundo o Larry Wall, preguiça, impaciência e arrogância, e é daí que vem o nome Impatient Programming.

[Rafael França 🇧🇷 @rafaelfranca]

If you put rust on the rails the train can derail. That is too dangerous.

[Irina Nazarova @inazarova]

Conferences should be open platforms. Orgs choose speakers but should not restrict anyone from participating. And vice versa: someone attending or speaking is not an endorsement of their opinions and political views. We have code of conduct (be respectful) and the law, and this is enough.

[Cirdes Henrique @cirdesh]

If you're at @railsworld and speak Portuguese, Spanish, or just want to find out what portunhol sounds like after a couple of beers, come find us Tuesday.
