In this episode, we had the absolute pleasure of sitting down with Carmine Paolino — an AI innovator, Ruby enthusiast, and all-around tech wizard. From his early days automating PC games at age five to building cutting-edge AI tools in Berlin, Carmine’s journey is as inspiring as it is impressive.

We dove deep into his latest creation: RubyLLM, a Ruby gem that simplifies working with large language models (LLMs) like GPT-4, Claude, and Gemini. Think of it as an intuitive, plug-and-play toolkit that lets Ruby developers tap into powerful AI features — chat, image generation, embedding, tools, and even multi-model support — with just a few lines of code. And yes, it’s as awesome as it sounds.

Key Takeaways:

• RubyLLM is built for simplicity and power. Carmine wanted a tool that “just works” — one unified interface for chatting, streaming, tool use, image generation, and more. It abstracts away the API mess and keeps things Ruby-friendly.
• Tooling support is next-level. RubyLLM allows for agentic AI by letting devs define tools (like checking the weather or sending a calendar invite). The gem handles when and how to use them — magic! 
• Support for multiple models and providers. OpenAI, Anthropic, Google — RubyLLM makes it easy to switch between them seamlessly, even mid-conversation. Carmine also teased a future integration with a smarter model registry via an AI-powered API called Parsera.
• Streaming and performance? Covered. Carmine shares clever architecture tricks using Turbo Streams and async Ruby for blazing-fast, lightweight responses — even when handling many concurrent users.
• Real-world use case: ChatWithWork. Carmine’s app lets users “chat” with their docs from Google Drive, Notion, and Slack. RubyLLM is the backbone, and it’s got real startup traction. (Oh, and he DJed the night it went viral on Hacker News.)
• Embeddings and image generation are just as easy. Need vector search or auto-generated podcast art? Just call .embed or .paint — seriously, that’s it.

Hey folks, in this week’s episode, I sat down with the incredible Ridhwana Khan — a South African technical writer for the Rails Foundation and lead engineer at Circle. We had a fantastic chat about all things Ruby on Rails, but especially the underappreciated art (and science!) of writing documentation.


Ridhwana took us behind the scenes of the official Rails Guides — how they’re updated, expanded, and reviewed — and gave us a real sense of the thoughtful, collaborative work that powers one of the best-documented frameworks out there. She also shared her personal journey: from freelancing into Rails doc writing, to her passion for building inclusive communities like Rails Girls South Africa and Black Girls Code.


Some standout takeaways:

• Metaprogramming = Superpower: We talked about the "magic" in Rails internals — especially metaprogramming — and how understanding it can make you a better developer. Ridwana gave a real-world use case from her time at Dev.to where metaprogramming enabled highly flexible custom profile fields. Elegant and practical!
  
  
• Docs as a Gateway to Contribution: Whether you're new or experienced, contributing to Rails docs is a great way to get involved. Ridwana encouraged folks to read the source code, dig into tests, and not be afraid to open a PR — even if it's small.
  
  
• Working on Circle: Ridwana’s team focuses on Circle's marketing and email hub features — think broadcasts, workflows, and analytics. She's leading the team (and hiring!), and we geeked out over async work, remote culture, and what makes for a great engineering org.
  
  
• Life in Cape Town: From houseplants to penguins, we veered off into Ridwana’s love of nature, her Arduino hobby projects, and even how Shark Week got us thinking about visiting South Africa someday.

This episode was equal parts inspiring and insightful — especially if you’ve ever looked at the Rails codebase and thought, “how the heck does this work?” Ridwana makes it feel accessible, and she’s proof that curiosity and community-building go a long way in tech.

In this episode of Ruby Rogues, Charles Max Wood and Ayush Nwatia welcome back guest Stephen Margheim to dive deeper into the evolving world of SQLite. Stephen explains that with Rails 8, SQLite has reached a major milestone: it now supports a fully production-ready, server-driven web application experience with no compromises. He walks us through the big improvements, like better transaction handling and SQLite’s integration with Rails, which now supports background jobs, caching, and WebSocket messaging—all powered by SQLite without additional configuration. These enhancements mean that deploying a Rails app backed entirely by SQLite is not only possible—it’s efficient, stable, and simple.

In this episode, we dove into a topic that’s been on our minds — how to navigate change with purpose instead of fear. Whether it's personal transformation, career pivots, or unexpected life shifts, we talked about what it takes to stay grounded and aligned during times of transition.

We opened up about our own experiences with change — the messy middle, the doubts, the resistance — and how we’ve learned to see it as a creative force rather than something to avoid. A big takeaway? Growth doesn’t always look graceful, but it’s often where the magic happens.

One of the key points we emphasized was the importance of self-trust. It’s easy to look outside ourselves for permission or validation, but true clarity comes from tuning inward. We shared tools that have helped us build that inner compass, like journaling, setting intentional pauses, and letting go of perfectionism.

We also touched on how community plays a huge role in transformation. Change can feel isolating, but when we open up and connect with others who’ve walked similar paths, it reminds us we’re not alone.

Key Takeaways:

• Change is a creative process, not just a disruption.
• Self-trust is your greatest guide through uncertainty.
• It’s okay to not have all the answers right away — clarity often follows action.
• Community and vulnerability are antidotes to isolation during transformation.
• Letting go of control creates space for something better to emerge.

We wrapped up with a little reminder: whatever shift you’re in right now, you’re not behind — you’re becoming.
