Remote Ruby

This week on Remote Ruby, Chris, Andrew, and David welcome Dan Manges, co-founder of RWX and former CTO of Braintree, to explore a new approach to continuous integration built for the age of AI coding agents. Dan explains how RWX uses intelligent caching, graph-based execution, and isolated agent sandboxes to dramatically improve development workflows. They dive into flaky tests, automated code validation, security concerns, and why traditional CI platforms may be struggling to keep up with AI-driven development. Plus, they discuss how engineering teams can test changes before opening pull requests, reduce infrastructure costs, and rethink the way software gets built and shipped.

Jeff Dickey is back on Remote Ruby, and he's been busy! Andrew and Chris catch up with Jeff to discuss the latest improvements to mise, including precompiled Ruby builds, automatic tool updates, and dotfile management. Jeff also introduces some of his newest projects, including packslip, a new standard designed to make software distribution more secure, and jactionlint, his modernized GitHub Actions linter. The conversation explores everything from managing secrets with fnox and cleaning up massive Rust build caches to running your own CI infrastructure at home. They also dive into AI-assisted development, the future of Ruby performance, and how AI is changing the way open source software gets built and maintained.

On this episode, Chris, Andrew, and David dive into the rapidly changing world of AI-assisted development, Ruby performance, and the future of building software. They kick things off with AI-powered coding workflows before exploring the Campfire benchmarking controversy and the exciting possibilities of Roundhouse, which could dramatically improve Ruby application performance. Andrew shares his experience launching a new AI agent inside Podia, including the challenges of getting its MCP integration approved by OpenAI, managing AI costs, and testing security. The conversation shifts to optimizing GitHub Actions, reducing CI expenses, and whether developers should start hosting their own runners. They also speculate about the future of all-in-one development platforms and how AI might reshape everything from writing code to deploying applications. Hit download now!

Fresh off Rails World 2026, Chris, Andrew, David, and returning guest John Athayde unpack the surprisingly emotional conversation surrounding AI, Ruby, Rails, and the future of programming. What starts as a discussion about Spinel, Roundhouse, Rust, and Rails performance quickly turns into a much bigger question: what happens to developers when writing code is no longer the main job? They dig into AI-assisted development, changing ideas around craftsmanship and creativity, the growing importance of testing and CI, and whether frameworks like Rails become more valuable in an AI-driven world. They also reflect on the mood at Rails World, autonomous cars, AI-generated design, and why the real value of conferences may increasingly be simply getting developers together in the same room.

Recorded live from Rails World 2026, Andrew, Chris, David, Jason Charnes, and eventually Andy Croll, unpack the strange mood surrounding this year’s conference. Much of the conversation centers on DHH’s keynote and the increasingly agent-driven future of software development: if AI can write, debug, and even understand the code for us, what happens to the value of frameworks, developer expertise, documentation, and even Ruby itself? They also dig into Hotwire, Active Search, Herb, Active Job Continuations, security concerns around AI-generated software, and what the Ruby community might rally around if the language becomes less central to how developers identify themselves. And because it’s Rails World, there’s plenty of barbecue, conference chaos, bad jokes, and Andy Croll crashing the podcast. Hit download now!

Andrew and Chris are back with a packed episode covering everything from Rails World anticipation and Rails 8.2 to security, Ractors, AI-assisted development, and some ambitious new Ruby tooling. They dig into RubyGems recent spam-publishing incident and Trusted Publishing, look at Shopify’s push toward Ractor-safe Rails, and explore Roundhouse, a project experimenting with compiling Rails applications into entirely different target languages. They also talk about using Claude for project planning and open source maintenance, new approaches to AI beyond traditional LLMs, the surprisingly inexpensive architecture behind Turbopuffer, PlanetScale’s new TIN search extension, and Andrew’s move from a small Sinatra deployment service to Cloudflare Workers.

Chris, Andrew, and David are back with a conversation that starts with Rails World plans. They break down APIs, webhooks, and persistent connections, using everything from thermostats to Stripe to explain how systems communicate and recover when things go wrong. From there, Chris shares what caught his eye in PlanetScale’s new Postgres sharding work, before the conversation shifts heavily toward AI-assisted programming, where the tools are surprisingly capable one minute and making baffling architectural decisions the next. They also explore how AI is changing Chris’s work on Jumpstart and Hatchbox, improving Rails actionable errors, tackling years-old Android bugs, and potentially reshaping how open source projects are maintained.

Ryan Castillo returns to the show to catch everyone up on what’s changed since his last appearance…and a lot has changed. Ryan explains why he and his co-founder moved on from their web application firewall Wafris and built Knowatoa, a platform focused on helping companies understand how their brands appear in AI-powered search. From there, the conversation expands into GEO and AI search visibility, multi-agent coding workflows, AI skills as the future of content, and when developers should or shouldn’t delegate work to AI. Chris also gets candid about Hatchbox’s recent pricing increase, the financial pressure behind the decision, and why talking directly with customers may be just as important as shipping the next feature.

This week, Chris, Andrew, and David dig into a packed mix of Rails news, developer tooling, and the increasingly complicated role AI is playing in everyday coding. They talk about Herb making its way into Rails, the realities of Rails upgrades and stacked PRs, new approaches to Git hosting and object storage, and how Rails is being evaluated in the age of AI agents. They also get into improvements coming to Action Text, Podia’s approach to “flavored” Markdown, the never-ending frustrations of HTML email, and why tools like ArchSpec and Rubydex could become especially useful as more code is generated by LLMs. Hit download now to hear more!

Andrew and David catch up on everything from wild weather and the upcoming Rails World conference to Andrew’s latest deep dive into MCPs (Model Context Protocols). Andrew shares what he’s learned while building an MCP for a Rails side project, including choosing the official Ruby MCP SDK, discovering the limitations of resources versus tools, and wrestling with OAuth and Doorkeeper authorization. They also look ahead to Rails World in Austin, highlighting talks on Active Search, Ractors, Herb, Action Text, Solid Cable, custom Rails generators, and appropriately enough MCPs.
