Exploring with agents

From Tailnet to platform
Adam talks with Tailscale co-founder and Chief Strategy Officer David Carney about where Tailscale is headed next: TSIDP, TSNet, multiple tailnets, and Aperture. They get into clickless auth (via TSIDP), TSNet apps, multiple tailnets for isolation and control, and Aperture, Tailscale’s private AI gateway for API key management, observability, and agent security.

Opus 4.5 changed everything
Burke Holland works on GitHub Copilot by day and codes with his AI agents always. Early January, Burke posted about how Opus 4.5 changed everything. We were all still buzzing from the holiday-season 2x usage bump Claude gave us, and Opus 4.5 felt like a genuine step function in capability. Burke and I get into all the details. Opus 4.5 may have started the fire, but GPT-5.3 Codex is certainly living up to the hype.

Selling SDKs in the era of many Claudes
Steve Ruiz joins us for a deep-dive on tldraw (a very good free whiteboard) and the business he's built selling SDKs that help others build very good whiteboards (and more) with tldraw's high-performance web canvas. Along the way, we discuss the excitement/fear we share about keeping our agents busy, how SDK and infra companies are affected differently by agentic software than SaaS companies, how Steve is approaching the coming era of internal tooling, what will happen when we equip LLMs with an infinite canvas, and more.

Building the machine that builds the machine
Paul Dix joins us to discuss the InfluxDB co-founder's journey adapting to an agentic world. Paul sent his AI coding agents on various real-world side quests and shares all his findings: what's going to prod, what's not, and why he's (at least for a bit) back to coding by hand. Update: He's back to letting the AIs write code, but with a lot more oversight. For now…

Setting Docker Hardened Images free
In May of 2025, Docker launched Hardened Images, a secure, minimal, production-ready set of images. In December, they made DHI freely available and open source to everyone who builds software. On this episode, we're joined by Tushar Jain, EVP of Engineering at Docker to learn all about it.

Securing npm is table stakes
As the creator and long-time maintainer of ESLint, Nicholas Zakas is well-positioned to criticize GitHub's recent response to npm's insecurity. He found the response insufficient, and has other ideas on how GitHub could secure npm better. On this episode, Nicholas details these ideas, paints a bleak picture of npm alternatives like JSR, and shares our frustration that such a critical piece of internet infrastructure feels neglected.

The era of the Small Giant
Damien Tanner (founder of Pusher, now building Layercode) is back for a reunion 17 years in the making. Damien officially returns to The Changelog to discuss the seismic shift happening in software development. From the first sponsor of the podcast to frontline builder in the AI agent era, Damien shares his insights on why SaaS is dying, why code review is a bottleneck (and non-existent for some), and how small teams can now build giant things.

From GitLab to Kilo Code
We're joined by Sid Sijbrandij, founder of GitLab who led the all-in-one coding platform all the way to IPO. In late 2022, Sid discovered that he had bone cancer. That started a journey he's been on ever since... a journey that he shares with us in great detail. Along the way, Sid continued founding companies including Kilo Code, an all-in-one agentic engineering platform, which he also tells us all about.

Agents in the database
Ajay Kulkarni from Tiger Data (Co-founder/CEO) is on the pod this week with Adam. He asked him to get vulnerable and trace his path to becoming a CEO. They dig into the themes that have shaped his career, and explore how founder values end up forming company culture (whether you intend them to or not). From his enterprise days to building Timescale (and the rename to Tiger Data), we cover the whole journey — even the haters, because haters gonna hate. Here's where it gets really interesting: Agents in the database! Not the hype. The real thing baby. They get into how fast you can go from idea to shipped these days, what it actually means to talk to your database, and the whole API/CLI/MCP/Skills movement.

Autonomous drone delivery in a Zip
We're joined by Zipline cofounder / CTO, Keenan Wyrobek. Zipline is on a mission to build the world’s first logistics system that serves all people equally via their fleet of autonomous drones that started in Africa delivering medical supplies and can now deliver packages (up to 8 lbs) directly to your door. They've solved a lot of gnarly technical and regulatory challenges along the way. We go deep with Keenan. We hope you'll find this one fascinating.

Werner Vogels predicts the future
Amazon CTO, Werner Vogels, stops by to help us explore his tech predictions for 2026 and beyond. Will companionship be redefined by consumer robots? Will quantum-safe become the only safe worth talking about? Is this the dawn of the renaissance developer? We're infinitely curious why Werner came to this particular set of conclusions. Are you?

The inner workings of Wikipedia
Let's hear how Wikipedia actually works from long-time Wikipedian, Bill Beutler! Bill has been heavily involved with this "8th wonder of the modern world" for two decades and even built a career on it, founding Beutler Ink –a digital agency known for its pioneering work in Wikipedia public relations. We discuss: the official (and not so official) rules, the editor cabal (which isn't one), the business model (which really isn't one), how an edit sticks (or not), how AI chatbots threaten the future of the site (or don't), and a whole lot more.

Creating communal computers
Spencer Chang caught our attention with the alive internet theory website, but he creates all kinds of computery things to bring people together around play, connection, and creation. Spencer's experiments with computing-infused objects inspired him to create an entire line of internet sculptures and real-world computing shrines that will hopefully inspire all of us to keep the internet alive and flourishing for years to come.

DO repeat yourself!
Prolific software blogger, Sean Goedecke, joins us to discuss why he believes software engineers need to be involved in the politics of their organization, how to avoid worry driven development, what is "good taste" in software engineering, where agentic coding will take our industry, why getting the main thing right is so important, and how to get your blog to the top of Hacker News.

The world of open source metadata
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.

Agentic infra changes everything
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.

Reinventing Python tooling with Rust
Charlie Marsh built Ruff (an extremely fast Python linter written in Rust) and uv (an extremely fast Python package manager written in Rust) because he believes great tools can have an outsized impact. He believes it so much, in fact, that he started an entire company that builds next-gen Python tooling. On this episode, Charlie joins us to tell us all about it: why Python, why Rust, how they make everything so fast, how they're starting to make money, what other products he's dreaming up, and more.

Voices of Oxide
Voices of Oxide on the pod! Cliff Biffle (engineer), Dave Pacheco (engineer), and Ben Leonard (designer) are on the show today. Jerod and I were invited to Oxide's annual internal conference called OxCon to meet the people and to hear the stories of what makes Oxide a truly special place to work right now. Cliff Biffle is working on all Hubris and firmware. Cliff says "There's a lot that happens before the 'main CPU' can even power on." Dave Pacheco is leading the efforts on Oxide's "Update" system. And Ben Leonard in charge of all things brand and design at Oxide.

Flowing with agents
Everything is changing. Adam is joined by his good friend Beyang Liu from Sourcegraph — this time, talking about Amp (ampcode.com). Amp is one of the many, and one of Adam's favorite agentic coding tools to use. What makes it different is how they've engineered to it to maximize what’s possible with today’s frontier models. Autonomous reasoning, access to the oracle, comprehensive code editing, and complex task execution. That's nearly verbatim from their homepage, but it's also exactly what Adam has experienced. They talk through all things agents, how Adam might have been holding Amp wrong, and they even talked through Adam's idea called "Agent Flow". If you're babysitting agents, this episode is for you.

XO Ruby is hitting the road
Jim Remsik has lived on the bleeding edge (but also the heart's center) of the Ruby world for decades. This fall, he's organizing six (yes, SIX) XO Ruby confs all around the United States.
