Rocky Mountain Ruby Conference

Thank you again to these sponsors!

Thank you closing us out, Alan Riddlehoover, with that look forward and back, and celebrating voices of computing that are often ignored! ♥️

Thank you lightning talks! Ruby Events Ruby-based systems Ractors Supply chain security

Welcoming back @i_ribon9 (Ifat), who shared how a solid testing foundation will also improve agentic testing in our apps (And check out that solid mountain metaphor in the 3rd slice 👀)

The Honeybadger balance board has a home! Thank you, @honeybadger.io! ♥️

In 5 weeks, @giovapanasiti built a RAG client in just Ruby, and then made it agentic with tools

Another returning speaker, Christine Seeman is sharing how mindfulness, growth mindset, deep work, and more make us better engineers and also happier humans

Everyone's reality now is onboarding to a new job with the reality of AI. @fomera is using her experience to give us a roadmap for using your agent to get you started

Huge thank you to sponsor Honeybadger for their support of Ruby communities! Wait for the drawing for this sweet board this afternoon 👀

Excited to welcome @marcoroth back to Colorado to share the reactivity, dev tooling, and great features that comes with the latest release of Herb bundled in Rails 8.2

So great to hear from organizer Bekki about micro communities and why organizers like building our local Ruby community!

Good morning! The day is starting similar to yesterday. Breakfast starts in ten min, and aim to be back in the auditorium again at 9 for Marco Roth

Knitting mentor / mentee at happy hour. See you tomorrow!

Enjoy drinks, more socializing, games, and/or learning to knit! See you same time tomorrow

You may just have to wait for the video of Travis Turner's closing remarks. Is it aliens? Is it God? Or just drugs?

~400 lines of Ruby to build your own agent - @DRBragg shows us just how easy it is to interface with a model to create a harness

Ben Reubenstein details the transformation of his commits for good while building FLYSoft and other projects

How long do your tests take to run? What maintenance work is outstanding in your app? Fernando Perales from @thoughtbot helps us think through signs that a Rails app is "rotting"

Breaking down the multiple types of AR class hierarchies in Rails (did you know there were 3?), @nicoerlichman is helping us understand the tradeoffs of STI, abstract classes, and delegated types

If you've considered whether you're ready for promotion or struggle with your staff role, Joel Hawksley oriented us to his priorities, challenges, and promotion path as a staff developer at @github

How would you prepare ahead of time for incident response and get better during? Sonja Peterson walks us through several strategies for better IR!

We have now been onboarded to build powerfuLLMachine as HUMANs who also need to think mindfully about their internal prompts and workflow, thanks to Kevin Murphy's delightful kickoff for day 1

Spike kicked off our speakers with his lightning talk about the chats we see in software development, ending with "never boring, never bored"

Booking my time off for work today because we're almost to Sep 28-29th, I reflected on how we have so many sponsors and how they make this worthwhile. Shoutouts to @gustohq, @honeybadger.io, @appsignal, @beflagrant.com, @typesense, and @evilmartians for making RMR not just doable, but a treat!

We're excited to welcome back Alan Riddlehoover to RMR! 250,000 tech workers laid off in a year. Alan is going to share the secrets of NASA's human computers for three strategies to stay indispensable in the age of AI. ❤️

UFOs. Theology. Psychedelics. What they share is a framework for understanding ontological shock, and AI is giving programmers exactly that. Travis Turner's talk is unlike anything else on the schedule. Strap in. 👽✨

Pager duty panic is optional. Sonja Peterson's incident response training plan will turn you into the engineer who *fixes* the outage—not the one who hides from it. 🚨 Catch her in Boulder in September! rockymtnruby.dev/tickets

ERB templates that actually understand HTML. Phoenix LiveView-style reactivity with zero new JS framework. Marco Roth is unveiling Herb + ReActionView for Rails 8.2. 🌿 Welcoming Marco back to Boulder for RMR! (Get your tix here: lnkd.in/gwG_WMZj)

Welcome to Hours Unlimited. Meet powerfuLLMachine. (Plot twist: it's all actually about humans.) Kevin Murphy's creative reframing of agentic practices will change how you think about LLMs (and your team!) 🧑‍💻 rockymtnruby.dev/tickets

Senior isn't the end of the road. GitHub's (and Boulder's) Joel Hawksley is breaking down what "staff" actually means and whether it's the right move for your career. Time to level up? 🚀 Welcome back to RMR, Joel! rockymtnruby.dev/tickets

The Ruby ecosystem stays healthy when companies actually using Rails put money back into it. Thanks to our sponsors for 2026 Rocky Mountain Ruby: @honeybadger.io, AppSignal, and Gusto❣️

AI can write 1,000 tests in an hour. But should it? Ifat Ribon is bringing the philosophy of *fewer, better* tests to the AI era. Quality over quantity, and confidence over coverage. 🎯 rockymtnruby.dev/tickets
