Keynote speaker by morning, saxophonist by night: @chadfowler closed day two at the piano and on a saxophone from David S. Ware's estate — with a Vienna story 30 years in the making 🎷

A conference talk that's also a clarinet duet 🎶 Dalma Boros & Jess Sullivan on saying yes to a surf trip with strangers — and everything that followed: a book club, hallway.party, and a first CFP that became this talk.

Is #Ruby the best language for building AI web apps? @paolino , creator of RubyLLM, makes the case: LangChain vs RubyLLM side by side, and zero to a streaming #Rails chat UI in a two-minute live demo.

youtu.be/t1XAy8HKvnY

15 years of #Rails + DDD — and why those lessons matter more than ever now that AI agents write code. @andrzejkrzywda on small read models, domains & processes, kept honest by Packwerk, RuboCop & Mutant.

youtu.be/zewTY3J42DU

Five lightning talks, five minutes each, one clap-off rule ⚡ @chikahirotokoro , @lreszke, @callmesangio, @RadanSkoric & @pragdave on OSS strategy, event sourcing, a lovable URL shortener, a Hotwire inspector, and picjs.

A quiet moment from day two: pianist Iman Jahić Hošić invited the room to slow down with a two-piece set at the grand piano of Das MuTh 🎹

#RubyConfAT #Vienna

"You're not writing Ruby right now. You're writing C++ with a Ruby syntax."

@pragdave closed #RubyConfAT 2026 with a challenge: classes are evil, your job class is just a function, and ActiveRecord::Base's 834 methods are not an "is-a" relationship.

▶️ youtu.be/hC943MiL0lg

He deleted his slides an hour before going on stage. It got better from there 🎤

@bbatsov : 14 years of RuboCop, 330 releases, zero breaking changes since 1.0 — and Rubydex integration that makes it "suddenly, magically smarter."

Also: many hot takes.

An event bus is just a mutex, a queue, and a thread. The rest is discipline.

Ljubomir Marković at #RubyConfAT 2026: from a naive bus in a few lines of #Ruby to TCB, a gem that fits your whole domain in one file — demoed on a live drum sequencer 🥁

▶️ youtu.be/bFGcJ5kOrOc

What if your frontend was just... #Ruby?

@AndyObtiva at #RubyConfAT 2026 on Glimmer DSL for Web — real frontend development in Ruby, no JavaScript, no backend tricks. A React component that took 1.5 months rebuilt in 1.5 days.

▶️ youtu.be/qTukq5AcSK0

Can you build software with AI agents and accrue zero technical debt?

@obie says yes — and shows how they do it at ZAR: 400k+ lines shipped in 5 months, automated constraints instead of PR reviews, and cleanup as a habit, not a backlog.

▶️ youtu.be/7QrXGLSZHvE

One stage. Four very different takes on AI 🎙️

@chadfowler , @josevalim , @obie & @mitsuhiko close day one of #RubyConfAT 2026: disposable code, "social coding is dead," why LLMs never pick Ruby — and what to do about it.

An hour of candid disagreement.youtu.be/ZsWRcX6hHO0

Not your typical conference recording 🎹

#RubyConfAT 2026 put a Bösendorfer grand on the program. Nadir Hošić's classical set at Haus der Musik — some Mozart, some magic, a hall full of Rubyists slowing down for 15 minutes.

Vienna, after all.

From Tasmania to Vienna 🇦🇺→🇦🇹

#RubyConfAT 2026: @MaediPrichard introduces Raindeer — an event-driven Ruby web framework born from a Sudoku solver and five seasons of Prison Break.

▶️ youtu.be/p9E5INAwK_4

Next up from #RubyConfAT 2026 🎬

@marcoroth_ on Herb & ReActionView: one parser for HTML+ERB powering editors, linting, an HTML-aware ERB engine, hot reloading — and LiveView-style reactivity for Rails.

▶️ youtu.be/rWi-zq62Nkk

The recordings are rolling out! 🎬

First up: @chadfowler 's opening keynote — "This Is What We've Been Training For."

25 years of Ruby culture were the training run for the AI era. The receipts, the Wunderlist story, and a live #Ruby agent demo.

And we're off!
