Sublayer and Artificial Ruby with Scott Werner
The Ruby AI Podcast
Intro
The hosts share a light-hearted discussion about their fashion choices in nerd culture, particularly T-shirts linked to the Ruby programming community. They also reminisce about quirky office traditions, weaving humor and nostalgia into their tech experiences.
Scott Werner—author of the Works on My Machine newsletter and creator of the Sublayer AI-agent framework—joins Valentino and Joe for a fast-moving conversation on how Rubyists are bending large-language models to their will. We unpack Sublayer’s “generators + actions” architecture, the delightfully chaotic Monkey’s Paw prompt-driven web framework, and Phoenix’s AI-generated test suites, all while debating what remains uniquely human in an age of code that writes itself. If you care about Ruby, rapid prototyping, and staying sane as models ship weekly, this one’s for you.
Show Notes
- Meet Scott Werner – from early Rails days to Works on My Machine and the Artificial Ruby meetup scene.
- Inside Sublayer – why “string-in → string-out” thinking led to Generators, Actions, and the idea of promptable architecture for code that assembles itself.
- Monkey’s Paw – a Ruby gem where Markdown “wishes” become full web pages via an LLM—hallucinations welcome.
- Blueprints & Semantic Linting – templated agent blueprints now built into Sublayer and text-based rules that keep AI code reviews on-message.
- Phoenix.love – Joe’s Rails-centric tool that churns out thousands of AI-generated tests and the ops pain (alerts, idle “vibe-waiting”) that follows.
- Feedback Loops & Human Taste – why Paul McCartney’s Get Back jam session is the right metaphor for iterating with an LLM collaborator.
- When the Model Eats Your Product – surviving weekly model upgrades, function-calling APIs, and the temptation to rebuild everything (again).
- Ruby’s Next Act – AI-inspired namespacing proposals, Ractors explained, and why dynamic languages still win the “unknown unknowns.”
- Show-and-Tell Picks
- Scott: TLDraw for visual AI pipelines.
- Valentino: “AI Software Architect” markdown blue-prints.
- Joe: “Demystifying Ruby” blog series on threads, fibers & ractors.
