November 04We now have Kerr’s Law (Changelog Interviews #689)
Dave Kerr created hacker laws, and now he finds himself reviewing agent-written code for them. Back on the show after six years, Dave names what he sees limiting teams today: keeping everyone’s mental model in sync with what’s actually been built. Adam declares it Kerr’s Law on the spot. We get into why Dave’s team treats code review as a deliberate slowdown, how Shellwright lets agents bring evidence to a pull request, and what living with bipolar disorder has taught Dave about noticing when the excitement of these tools stops being healthy.

October 28The future is Postgres (Changelog Interviews #688)
Craig Kerstiens returns to talk about the ever-expanding world of Postgres: a deliberately boring core, a thriving extension ecosystem, and pg_lake bringing DuckDB and Iceberg into the mix. We dig into the pain of ETL, what Craig is watching in Postgres 19, the impact of AI on open source maintainers, and why the database still has plenty of room to grow.

October 22Building what's next (Changelog Interviews #687)
This week I’m talking with Zeno Rocha, CEO of Resend, about scaling “boring” email to 3 million users, the secret Go rewrite behind it, and building for agents. We cover pricing.md, MCP, spam gangs, and why Resend keeps what’s next for email.

October 09From zero to NanoClaw (Changelog Interviews #686)
Gavriel Cohen, creator of NanoClaw and co-founder of NanoCo, joins Adam to explain how a 40-hour weekend project became a viral open source hit and the foundation of an enterprise AI company. Gavriel describes the security concerns that led him to build a small, container-isolated alternative to OpenClaw, why he released it under the MIT license, and why the project’s community and credibility are more valuable than keeping its code private.
They explore the shift from writing code to architecting the environments in which agents work, NanoClaw’s “skills over features” approach, the approval and governance layers required inside large companies, and a future where every worker manages agents without surrendering human judgment. They close with the technical simplicity behind NanoClaw, containers, TypeScript, SQLite, and a two-database design, and Adam’s case for durable Agent Flow artifacts that keep organizational context from disappearing into chat.

September 03Forking Cal.com to closed source (Changelog Interviews #685)
This week I’m joined by Peer Richelsen, co-founder of Cal.com. What if the majority of open source repositories are already compromised and we just don’t know it yet? That’s the theory Peer brings to the table this week. We dig into how AI has flattened the knowledge graph to the point that a 16-year-old can vibe hack a power station just as easily as their mom can vibe code an iOS app, why the reporting culture that has kept open source safe all these years is collapsing under AI generated noise, Cal.com’s move to fork its own codebase and take the sensitive parts private, and the eye opening reality that shipping “$1 of AI tokens for pennies on the dollar” is now a common startup business model.

August 25Postgres at PlanetScale (Changelog Interviews #684)
Sam Lambert is back after 4 years and he does not hold back! We cover $5 PlanetScale Postgres, the Neki “do-over” of Vitess, agents shipping schema changes through deploy requests, rolling back a 500TB table in seconds, and the very real question of whether to open source any of it. Plus: why he thinks the sleeping, lazy giants should be broken up.

Haroon Meer is back! Haroon is the Founder of Thinkst, the ~50-person bootstrapped company behind Canary and Canarytokens — honeypots and tripwires you sprinkle inside your network and forget about until an attacker touches one. We talk about the AWS API key token attackers just can’t resist trying, the real credit card token backed by an actual bank partnership, Breadcrumbs (their brand-new feature that leads intruders straight to your canaries), a live demo where a hardware Canary becomes a Synology NAS in one click, and how a company with zero outbound sales and no price increase in ten years quietly passed $22.5 million in ARR.

June 05From open source hits to OpenAI (Changelog Interviews #682)
This week I’m talking with Max Stoiber, currently working on ChatGPT’s plugin directory and app platform at OpenAI. We discuss the hundreds of open source projects nobody remembers alongside the big ones like react-boilerplate and styled-components, how Spectrum became part of GitHub and eventually helped shape GitHub Discussions, the founder growth that came from building Stellate, the GraphQL cache that turned into a dual acquisition by Shopify and The Guild, and why ChatGPT apps feel like a new surface for software.

May 15MCP on Code Mode (Changelog Interviews #681)
This week I’m talking with Matt Carey about Code Mode and how most of us have been thinking about MCP all wrong. Matt works on the Agents SDK and MCP at Cloudflare — we discuss how server-side Code Mode lets one MCP server expose all ~2,500 Cloudflare API endpoints in about 1,000 tokens of context, the dynamic Worker loader that runs model-written code safely in a V8 isolate, Matt’s own workflow with Claude, where memory fits into the future of agents, and his Zaggy git wrapper that keeps agents from force-pushing his repos.

May 13Automation at the speed of Swamp (Changelog & Friends #130)
This week I’m talking with Adam Jacob, founder of System Initiative and creator of Swamp, about what happens when AI agents change the entire shape of software development. We discuss how he went from an 18-person team down to five and shipped Swamp 900 times in four weeks, why he brought User Acceptance Testing (UAT) testing back from the 90s, why software architecture (and domain-driven design) suddenly matters more than knowing how to write code, the live demo where I pointed Swamp at my Proxmox box and watched it write its own automation (blew my mind!!), and why he’ll never accept a pull request to Swamp, ever.
