Spec-driven development with Kiro (Changelog Interviews #662)

It's our first Kaizen after the big Pipely launch in Denver and we have some serious mopping to do. Along the way, we brainstorm the next get-together, check out our new cache hit/miss ratio, give Pipely a deep speed test, discuss open video standards, and more!

Ellie Huxtable's magical shell tool, Atuin, won developers' hearts by syncing, searching, and backing up our shell history with ease. Now Ellie is tackling the desktop with a GUI built to help teams make their workflows repeatable, shareable, and reliable.

Csaba Okrona lays out exactly what Flow is (then shows you how to engineer your way back to it), a smart vacuum turned against an innocent hacker, Matz and the Ruby core team step up to steward RubyGems, Simon Willison things Claude Skills could be bigger than MCP, and Luke Plant looks at technical debt from a more positive perspective.

Mike McQuaid and Justin Searls join Jerod in the wake of the RubyGems debacle to discuss what happened, what it says about money in open source, what sustainability really means for our community, making a career out of open source (or not), and more. Bleep!

We're joined by Deepak Singh from the Kiro team. Kiro is AWS's attempt at building an AI coding environment to take you from prototype to production. It does that by bringing structure to your agentic workflow with spec-driven development. Their aim: the flow of AI coding, leveled up with mature engineering practices.

Denis Stetskov describes how we've "normalized catastrophe" in the software industry, Meta is officially handing React and React Native over to a foundation, The New Stack reports on GitHub's Azure migration priority, Miguel Grinberg benchmarks Python 3.14, and The Oatmeal's Matthew Inman published his take on AI art.

Elixir creator, José Valim, is throwing his hat into the coding agent ring with Tidewave –a coding agent for full-stack web development. Tidewave runs in the browser alongside your app, but it's also deeply integrated into Rails and Phoenix. On this episode, José tells us all about it. Also: his agent flow, YOLO mode, an MCP hot take, and more.

Our friends at Cult.Repo launch their epic Vite documentary on October 9th, 2025! To celebrate, Jerod sat down with Evan You to discuss Vite's adoption story, why he raised money to start VoidZero, how developer documentaries get made, open source sustainability, and more.

Abner Coimbre makes a compelling case why our biggest technical talent should abandon for-profit social platforms, Noah Brier creates a Claude Code and Obsidian starter kit, Bharath Natarajan documents the Vercel vs Cloudflare fight, Toolbrew is a well-designed website brimming with common utilities, and Yusuf Aytas analyzes why over-engineering happens.

Over the past two months, we’ve seen some of the most serious supply chain attacks in npm history: phishing campaigns, maintainer account takeovers, and malware published to packages with billions of weekly downloads. What is going on?! What can we do about it? Our old friend, Feross Aboukhadijeh, joins us to help make sense of it all.
