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

Andrew Nesbitt builds tools and open datasets to support, sustain, and secure critical digital infrastructure. He's been exploring the world of open source metadata for over a decade. First with libraries.io and now with ecosyste.ms, which tracks over 12 million packages, 287 million repos, 24.5 billion dependencies, and 1.9 million maintainers. What has Andrew learned from all this, who is using this open dataset, and how does he hope others can build on top of it all? Tune in to find out.

Ahmad Alfy explains how URLs are state containers, Shrivu Shankar shares how he uses every Claude Code feature, Yusuf Aytas laments how AI broke technical interviews, Wu Xiaoyun tells how he saved TikTok $300k during his internship, and TOON is a new serialization format to save us some LLM tokens.

It's a FRIGHT...when your record a podcast with dead projects all around. Tech debt, poor choices, timing, market shift, and optimizing for the wrong things are all lurking around waiting to pop out at you! Just don't forget to push record.

Adam Jacob joins us to discuss how agentic systems for building and managing infrastructure have fundamentally altered how he thinks about everything, including the last six years of his life. Along the way, he opines on the recent AWS outage, debates whether we're in an AI-induced bubble, quells any concerns of AGI and a robot uprising, eats some humble pie, and more.

The Dead Internet Theory dies, Geoffrey Litt tries to code like a surgeon, Matt Sephton thinks spreadsheets are great for UI design, Nate Meyvis advocates for front-end maximalism, Hemant Pandey thinks 9-5 employment is a great option for most, David Miranda compares React to Backbone in 2025.

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.
