I went to @noelrappin.com's workshop! I liked the reminder to think about pure Ruby objects, and agree that data validation replaces static type checking.

I was too shy to take photos in such a cozy space, but thankfully all the workshops were recorded!

Sarah Mei is back!! I really loved how she addressed that some AI hesitancy is based on personal fears expressed as societal fears. I also completely agree with her vision of the future. But I think we'll see more small-scale niche projects too.

Sarah Mei on stage - the slide next to her says "The Panic Discourse" and features a bunch of headlines panicking about AI. My favorites are "The AI coding apocalypse" and "'It's a bloodbath out there': Tech workers forced to take 'survival jobs' as AI cuts swath through workforce". Sarah Mei on stage, the slide next to her says: Current shift: AI Coding Assistants Speculation: - Applications can be written faster - More applications will be written - More ambitious applications - More types of people can write them Sarah Mei laughing at her own joke. Sarah Mei looking concerned and the slide next to her reads: Our Personal Fears - I'll lose my job - Software jobs will lose prestige or pay less - The hard-won skills I have are suddenly useless - The thing I like about this job is going away

Tech is great, but you need people to buy into your product or project! @leenyburger.bsky.social's talk was a great overview of some different ways to get people interested in your project! I really liked the points about post quality and building trust.

This talk from @obiefernandez.bsky.social was a great explainer on how our understanding of the software development process needs to evolve with AI!

I loved the point about shared human and AI frustrations. New AI tools and docs are helping both!

Obie looks at the slide: Why does process exist again? Reduce uncertainty and coordinate humans - Create predictability in an inherently unpredictable activity - Manage risk (technical, timeline, communication, scope) - Align people so teams don't drift, duplicate work, or miss expectations - Ensure feedback happens before mistakes get expensive - Provide shared rituals that help groups make decisions and adapt Obie has updated the previous slide for AI Why does process exist again? **(2025)** Reduce uncertainty and coordinate humans **and their AI agents** - Create predictability in an inherently unpredictable activity - Manage risk (technical, timeline, communication, scope) - Align agents so they don't drift, duplicate work, or miss expectations - Ensure feedback happens before too many tokens get wasted - Provide shared rituals that help groups make decisions and adapt Everything that frustrates you in a codebase also frustrates your coding agents. Just in different ways. Humans get confused. AI gets unpredictable. Humans feel overwhelmed. AI loses coherence in its generation. Humans slow down. AI drifts, hallucinates, or contradicts itself. Obie stands on stage, pointing at the audience. He's wearing a black shirt with the words "dangerously skip permissions" printed in large letters on it.

We need to be louder! Surprisingly few people in the broader engineering community understand that Ruby powers a disproportionally huge amount of Bay Area's most successful startups. From GitHub and Stripe to Chime and Stackblitz, Ruby powers teams that go HUGE with less.

RubyLLM is such an incredibly clean interface for building apps that use AI! I appreciate @paolino.me's passion for simple interfaces and the philosophy behind it.
Carmine points at a slide: This is Ruby's time to shine in AI Carmine staring out at the audience. Carmine on stage. Slide says: The RubyLLM Philosophy 1. Simple should be simple, complex should be possible 2. Models and providers are commodities 3. Convention over configuration 4. Progressive disclosure 5. One API, for One Person, in One Machine Carmine pointing at a slide demoing RubyLLM. Track usage with RubyLLM ``` response = RubyLLM.chat(model: "gemini-2.5-flash").ask("What's the oldest known example of conifers?") response.input_tokens # => 12 response.output_tokens # => 1279 ```

I was really excited about @josevalim.bsky.social's talk because I'd heard good things about Tidewave, but now I'm more excited by some of the suggestions he made.

The idea of a runtime API for fetching documentation is fascinating to me!

José pointing at the slides, face serious. José addressing the crowd, the slide next to him says: Integrate coding agents into what you are building - Writing scripts, libraries, frameworks => EDITOR - Building web applications => BROWSER - Running data analysis and reports => NOTEBOOKS - Crafting a game => GAME EDITOR Unified documentation - Hard to access, no metaprogramming, no doctests - Proposal: runtime API to fetch documentation (see Python, Elixir, Clojure, PHP) - Proposal: unified documentation website José addresses the audience, next to him is the slide: Structured templates - ERB builds HTML using string interpolation - No structure, no validations - HERB(HTML+ERB) to the rescue?

I GOT MY RUBY PASSPORT!!!! ❤️🛂

Thank you to @sfruby.com and @therubypassport.com for organizing an embassy!! ❤️❤️❤️
An open Ruby Passport in front of a window overlooking the tarmac at SFO. An attempt has been made to make block letters and emulate a real passport, but it has failed. The ink is smudged and dates have been scratched out and updated. The photo is a stiff, dead-eyed smileless stare like a real passport. First name: RACHAEL Last name: WRIGHT-MUNN Date of birth: (left blank) Nationality: UNITED STATES Signature: (squiggly ChaelCodes signature) Date and event of issue: 19 Nov 2025 SF Ruby Date and version when you started using Ruby: 10 Jul 2014, 2.1 Date and version when you started using Rails: 03 Mar 2015, 4.2.0 Colorful flag pennants adorn the wall as two volunteers help someone with their first Ruby Passport. Colorful flag pennants adorn the wall, and props cover the table. The photographer stands by, waiting for the next Rubyist. A screenshot from RubyEvents.org of Chael's profile. There are now 3 icons next to her name - verified, **Ruby Passport**, and contributor.

I really liked @adrianthedev.com's talk about the asset pipeline. The historical perspective and comparison of different ways to handle js and assets was interesting. Especially how to include assets in gems (like Avo)!

www.rubyevents.org/talks/master...
Adrian smiling and laughing on stage. Adrian on stage emoting with the audience. Adrian on stage next to a slide: What did we learn? - The asset pipeline is powerful - importmaps is low-hanging fruit - esbuild is powerful and easy to integrate - we can create gems with perfectly delivered assets Adrian introduces a summary of the talk. Summary 1. What are assets? 2. How it was in the ol' days 3. Why do we have an asset pipeline? 4. Where are we now 5. How can we leverage it to build effective Rails plugins

Learning about building MCP tooling to better understand your application with @baweaver.bsky.social was fascinating!! The questions AI is able to answer when it has access to introspection from Packwerk and Rails is really cool!
Packed Blackbox Theatre - standing room only. Brandon stands at the podium, the slide says "...but What if AI? MCP Tools" Brandon addressing the audience Brandon addresses the audience. The slide is slightly washed out from sunlight. Macro Tools QueryPackwerkTool Comprehensive Packwerk query with multiple query types: - packages - List all packs - violations - Basic violation counts - ownership - Who owns what - patterns - Most violated code with usage patterns - consumers - Who uses a pack - producers - What a pack uses - graph - Full architecture analysis (dependencies, circular deps, team coupling) - suggestions - Refactoring ideas Brandon addresses the crowd and slide (slightly washed out from sunlight) says: The Actual Value - "What does my team own?" -> 2 seconds instead of 20 minutes - "Where is this used?" -> instant instead of grepping - "What breaks if I change this?" -> analysis instead of guessing - "What's blocking the sprint?" -> instant instead of opening Jira - "Find the deployment docs?" -> instant instead of searching confluence For onboarding: Instead of 3 months to understand the codebase + tools + processes, maybe 3 weeks. For daily work: Less context switching between tools.

Herb continues to enable incredible advances in the developer experience of html+erb thanks to @marcoroth.dev's work. There was a spontaneous round of applause for the new error page of ReActionView.

Even as I was getting my mic, I was on tiptoe trying to see what the latest is.

Marco on stage. The slide "Herb to ReActionView: A New Foundation for the View Layer" Marco on stage next to a slide "Ruby is elegant. Ruby is expressive. Ruby is a joy." Marco on stage looking serious. Terribly distorted slide from the camera angle and sun hitting the screen of the Herb logo and parsed output of a template.

To start off the conference @inazarova.bsky.social thanked everyone who was involved in making this conference happen and reminded us why we're here–to learn how to build the future in Ruby!

I love how cool and zen the zero gravity lounge is. This and the Ruby Warrior room are my go-to places to hide and be comfy.
Evil Martians socks hidden in the end tables. A sign saying "ATTENTION ZERO GRAVITY" painted on the wall, and a flashing alarm light above the door. A dim room with red lighting and modern curved angular couches. Imagine an octagon but with 3 segments missing.

This venue is absolutely gorgeous!! I'm loving the transparent chairs and conference spaces!
Open main stage seating with transparent red chairs. The San Francisco Ruby Conference banner is flanked by two led screens with the logo on them. Long modern tables with transparent chairs in rows for the workshop studio. A moody theater with the walls painted black and the wall has a video of the SF Ruby Conference logo projected on it. A crowded sponsor room with a screen printing setup for the t-shirts.
