The Changelog: Software Development, Open Source

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.

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.

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.

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.

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.
