    AI-Powered Rails Upgrades with Ernesto Tagwerker: NextRails and the Future of Framework Modernization

    Send us Fan Mail When AI Refused to Listen and Then Became the Best Developer on the TeamRarely does a story about an AI tool actively resisting instructions end up being the most compelling argument for using that tool. When Claude initially pushed back against adding conditionals for dual booting large legacy Rails applications, the team at FastRuby had to essentially teach it their own hard-won expertise rather than letting it default to general Stack Overflow consensus. Ernesto Tagwerker from OmbuLabs and FastRuby joins Valentino Stoll and Joe Leo to unpack what that process actually looks like in practice. The conversation covers dual booting (running test suites against multiple Rails versions simultaneously), encoding human experience into AI-usable skills, and the shift toward outcome-based value rather than hourly billing. After more than 60,000 development hours across eight years of Rails upgrades, FastRuby has started consistently beating their project estimates with one human and one AI agent matching two humans' output. What does it actually mean to keep humans in the loop when AI handles ninety percent of implementation work? Ernesto argues that Ruby's readability makes it especially valuable precisely when humans need to oversee and debug AI-generated code. Genuinely, the point lands well and stays with you. Tune in for a grounded, honest look at where AI genuinely helps and where it still falls short.

    Ruby Central, Vibe Coding Ceilings, and What Still Requires a Human: Michael Rispoli on the Work AI Cannot Take

    Send us Fan Mail Joe Leo hosts the Ruby AI Podcast with guest Mike Rispoli, discussing Ruby Central’s financial instability, leadership changes, the Ruby Alliance (including Gusto joining), and concerns about fragmentation in the Ruby ecosystem after RailsConf’s end and uncertainty around RubyConf. They compare governance models (benevolent dictator vs committees) and debate centralized package infrastructure versus decentralized approaches amid growing security threats. Rispoli explains Cause of a Kind’s rebrand toward “modernize your software,” focusing on high-security verticals (healthcare, education), migrations, PE-driven remediation, and an on-site “War Room” offering, aiming to avoid work that can be easily “vibe coded.” They cover rising importance of continuous security testing, shifting client expectations, anti-patterns in AI-built products, and Rispoli’s multi-model AI coding workflow (Claude, Kimi, Qwen, Codex/GPT 5.5) plus training engineers in forward-deployed skills via his “Behind Enemy Lines” series. 00:00 Welcome and Guest Intro 00:32 Gusto Joins Ruby Alliance 01:59 Is Ruby Central Ending 03:28 Governance Models Debate 06:46 Conferences and Community Shift 08:15 Centralized Packages vs Git URLs 09:17 Cause of a Kind Rebrand 11:21 Modernization and War Room 14:05 AI Pressure and Agency Strategy 18:25 AI Builds Faster Rails Rewrites 21:40 Security Chaos Monkey Era 25:31 Tooling Diversification 26:50 Testing Alternatives 28:00 GPT 5.5 Workflow 30:48 Switching Model Harnesses 31:50 When to Go Solo 34:28 Vibe Coding Pitfalls 36:16 Marketing First MVP 39:02 Teaching FDE Skills 43:08 Selling Pushback 47:44 Closing and Meetup

    Minerva Magic: OpenClaw, Agent Status Pages, and Training an AI Coworker in Ruby on Rails

    Send us Fan Mail What happens when you treat an AI agent like a co-founder instead of a tool? In this episode, Valentino and Joe go deep into a real-world experiment: spinning up an autonomous agent using OpenClaw, giving it domains, goals, and just enough guidance to build an actual business. From creating accounts and managing projects to writing code, deploying with Kamal, and even designing its own training curriculum, the agent evolves from confused assistant to something resembling a junior engineer with initiative. Along the way, they explore the messy reality of agent workflows: memory systems, self-training loops, PR reviews, hallucinated confidence, and the constant tension between autonomy and control. The result? A working product, 15 early users, and a pile of hard-earned lessons about what AI can and definitely cannot do today. If you’re building with agents, thinking about autonomous systems, or just curious what happens when you let AI run a startup… this one’s for you. 🔗 Show Notes - Valentino's Minerva Experiment - Minerva's First Product Core Tools & Frameworks - RubyLLM (Carmine Paolino) - Kamal (Deploy Rails anywhere) - Tailscale (Secure networking) Libraries & Infra Mentioned - ExtraLite (SQLite performance layer) Learning & Community - Ruby AI Newsletter (Matt Solt) Other Mentions - OpenClaw - Claude Code - Action MCP - Fizzy (37signals) - Magic Beans (graph-based project management for agents) - ups.dev (agent status pages project) - DailyVibe.ai Books & Resources Referenced - Practical Object-Oriented Design in Ruby by Sandi Metz - Programming Ruby (Pickaxe Book) - The Well-Grounded Rubyist - Layered Design for Ruby on Rails Applications — Vladimir Dementyev Cultural Reference - Wired article on AI-generated band marketing (“Geese”) 00:00 Podcast kickoff 00:40 Geese AI marketing psyop 02:03 Starting an AI band 04:18 Daily Vibe artist generator 06:24 Open Claw origin story 08:52 Domains to business ideas 10:44 Onboarding an AI coworker 13:22 Handholding and action loops 14:10 Shark Tank idea filter 15:32 Training and memory system 20:20 UPS dev agent status pages 22:54 Rails build struggles 24:04 Bootcamp with Ruby books 26:20 Rebuild MVP and open source 27:55 Deploying with EC2 28:38 Locking Down Access 30:06 AI PR Reviews 32:50 Self QA Automation 36:11 Fixing Agent Memory 38:15 Email and Token Costs 40:11 Heartbeats and Delegation 43:01 Customer Discovery Lessons 44:49 Selling Workflow Friction 48:19 Knowledge Base Frameworks 51:37 Open Source Model Future 53:57 Security Agents and Wrap

    You Can’t Vibe-Code Trust: Scaling AI Safely with Bekki Freeman

    Send us Fan Mail Valentino Stoll and co-host Joe Leo open the Ruby Podcast noting OpenAI is winding down its SOA video app and discuss the broader difficulty of building AI businesses. Guest Bekki Freeman, staff software engineer at Caribou Financial and organizer of Rocky Mountain Ruby, shares conference details (Boulder, Colorado at eTown, September 28–29; CFP opening soon; tickets after the schedule). The conversation focuses on safely scaling AI use in an 8-year Rails monolith: preparing messy codebases with dead code and metaprogramming, strengthening test harnesses and coverage, improving documentation, and being explicit about desired patterns rather than copying existing bad ones. They discuss PR review bottlenecks from increased AI-generated PRs, ideas like specialized AI review agents, stronger RuboCop rules, pairing/mobbing, and remote knowledge-sharing practices, plus security cautions and what AI may and may not replace (tech-debt work vs “taste”). 00:00 Sora Shutdown News 00:57 AI Hype Reality Check 01:43 Meet Bekki Freeman 02:00 Rocky Mountain Ruby Update 04:32 AI Meets Legacy Rails 07:22 Prep Codebase for AI 10:06 Patterns Versus Best Practices 12:37 Testing Strategy and TDD 16:45 PR Review Bottlenecks 19:27 Specialized Review Agents 21:31 Defining Quality Context 24:29 Humans and Team Adoption 25:20 Remote Change Adoption 27:00 Creating Sharing Rituals 29:19 Release Calls As Watercooler 30:12 Mob Sessions With Agents 33:55 Security And YOLO Risks 35:45 Too Much Code Problem 37:16 Vibe Coding Vs SaaS 42:10 AI Engineering In Two Years 45:33 Codex Versus Claude 47:39 Wrap Up And Farewell

    You Can’t Vibe-Code Trust: Why Real SaaS Still Wins in the AI Era

    Send us Fan Mail On the Ruby AI Podcast, hosts Valentino and Joe Leo welcome Scholarly CTO/co-founder Kelly Sutton to discuss building a vertical SaaS “faculty information system” for universities. Sutton explains why competitors can’t easily replicate Scholarly: higher ed is moving off decades-old homegrown software, and the product must meet trust, security, compliance, and regulatory demands such as SOC 2 Type II. He describes how Scholarly expanded from replacing Excel/Access tracking to sophisticated workflow automation and how universities recently shifted from AI skepticism to AI FOMO. Scholarly uses AI in product surfaces, heavily in engineering, and via an admin MCP server that helps ops/customer success rapidly configure workflows from faculty handbooks with human-in-the-loop review. The conversation debates MCP’s likely temporariness versus traditional APIs, emphasizes smaller reviewable “PR-sized” outputs, and frames AI as an implementation detail focused on customer value. Valentino also shares an experiment training Claude to build products, including ups.dev and an open-source Ruby uptime-monitoring gem.

    CRMs Don’t Have to Suck: Rebuilding Business Software with AI and Ruby with Thomas Witt

    Send us Fan Mail Many “AI startups” today are little more than thin wrappers around large language model APIs. But what happens when those APIs improve and the platforms absorb those features? In this episode of The Ruby AI Podcast, Valentino Stoll and Joe talk with builder and investor Thomas Witt, founder of Vendis.ai and operator of the pre-seed firm Expedite Ventures. Thomas shares why he believes the next generation of durable companies must deliver real value deep in the product stack rather than bolting chat onto existing software. The conversation explores why traditional CRMs are widely disliked and how an AI-native CRM might look completely different. Instead of rigid forms and required fields, Thomas describes a system where conversations themselves become the primary data source. Emails, meetings, and messages are embedded, searched semantically, and transformed into structured knowledge automatically. They also dive into the architecture required to support this shift. From Ruby on Rails and Hotwire to DynamoDB, vector search, async Ruby, and multi-model LLM workflows, Thomas shares practical lessons from building AI-heavy production systems. Along the way the discussion touches on agentic coding workflows, LLM-as-a-judge evaluation patterns, telemetry for prompt chains, and why small teams may soon replace the massive engineering orgs we’ve grown used to. If you’re curious where Ruby, Rails, and AI systems are heading next, this conversation offers a fascinating glimpse. Show Notes Guest: Thomas Witt Founder of Vendis.ai Investor at Expedite Ventures Topics we explore • Why many AI startups are just “wrappers” around LLM APIs  • What an AI-native CRM looks like when conversations become the database • Why Thomas chose Ruby on Rails with minimal JavaScript using Hotwire and Stimulus • Using Amazon DynamoDB instead of relational databases for AI workloads • Hybrid keyword + vector search with OpenSearch and Elasticsearch • Async Ruby patterns using fibers, the Async ecosystem, and the Falcon web server • Orchestrating many concurrent LLM calls within a single user interaction • Background job systems and queues such as Amazon SQS • Code quality workflows with StandardRB and RuboCop • Using models like Claude, OpenAI Codex, and Gemini together in multi-model workflows • Observability and prompt tracing with Langfuse • Why AI tooling may enable much smaller engineering teams Mentioned in the Show • Vendis.ai – Thomas’s AI-native CRM platform • Hotwire – HTML-over-the-wire approach for modern Rails apps • Falcon – Fiber-based Ruby web server • Ruby AI Builders Discord – Community of Ruby developers building AI tools • Chaos to the Rescue @ Artificial Ruby
