Changelog Interviews

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 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.

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.

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. On this episode, Jim joins us to reminisce about the early days of Ruby and Rails, share what he's learned from so many years of organizing events, and invite all of us to join him on his upcoming 7500 mile road trip.

Our friends at Cult.Repo launched their epic Python documentary on August 28th, 2025! To celebrate, we sat down with Travis Oliphant –creator of NumPy, SciPy, and more– to get his perspective on how Python took over the software world. Stick around for the twist ending! We set aside Python and dissect Travis' big idea to make open source projects financially sustainable through direct investment.

The epic show with Adam Jacob has been remastered! Now with full-length video on YouTube. Adam goes solo with Adam Jacob for an epic pod into his journey to get to System Initiative. From SysAdmin at 8 years old, to discovering Linux and working for Mom-and-pop ISPs, to open source changing his life and starting Opscode and building Chef. Buckle up and enjoy.

Dr. Ewelina Kurtys is leading the way in biocomputing at FinalSpark where she is working on the next evolutionary leap for AI and neuron-powered computing. It's a brave new world, just 10 years in the making. We discuss lab-grown human brain organoids connected to electrodes, the possibility to solve AI's massive energy consumption challenge, post-silicon approach to computing, biological vs quantum physics and more.

We're LIVE at the historic Oriental Theater in Denver, CO with Nora Jones. Nora is the founder of Jeli.io, recently acquired by PagerDuty and she's been shaping the way we think about reliability, incident response, and human-centered engineering for years. We get into the real story behind the deal. Not just the headline, but what it’s like selling your company, what it takes to actually integrate a product into a larger platform, how customers responded, what changed for her team, and why her new role at PagerDuty is basically everything she was building Jeli for.

Greg Osuri, Founder and CEO of Akash Network joins us to share the backstory in his testimony before congress on the energy crisis and what it's going to take to power the future of AI. From powering datacenters, to solar, decentralized AI compute, to zombies in SF.

Sugu Sougoumarane, creator of Vitess, comes off sabbatical to bring Vitess to Postgres. We discuss what motivated Sugu to come off sabbatical, why now is the time, the technical challenges of doing so, the implementation details of Multigres (Vitess for Postgres). We also discuss the state of Postgres at scale.

David Hsu from Retool joins Adam to discuss how he built Retool. From the pivot in YC, to building the most widely used internal tools platform, to now being the platform for AI agents in the enterprise—on this episode we cover David journey from YC to building agents for the enterprise.

We talk with Don MacKinnon, Co-founder and CTO of Searchcraft—a lightspeed search engine built in Rust. We dig into the future of search, how it blends vector embeddings with classic ranking, and what it takes to build developer-friendly, production-grade search from the ground up.

Thorsten Ball returned to Sourcegraph to work on Amp because he believes being able to talk to an alien intelligence that edits your code changes everything. On this episode, Thorsten joins us to discuss exactly how coding agents work, recent advancements in AI tooling, Amp's uniqueness in a sea of competitors, the divide between believers and skeptics, and more.

Chris Anderson joins the show. You may recognize Chris from the early days of CouchDB and Couchbase. Back when the world was just waking up to NoSQL, Chris was at the center of it all, shaping how developers think about data distribution and offline-first architecture. These days, Chris is working on Vibes.diy and Fireproof — tools that make one-shot app generation not only possible, but shareable within minutes. We talk about the origins of CouchDB, the fork that led to Membase and Couchbase, and how that long journey led to this new paradigm: Vibe Coding.

Jerod is joined by Carson Gross, the creator of htmx –a small, zero-dependency JavaScript library that he says, "completes HTML as a hypertext". Carson built it because he's big on hypermedia, he even wrote a book called Hypermedia Systems. Carson has a lot of strong opinions weakly held that we dive into in this conversation.

Jerod chats with Richard Feldman about Roc – his fast, friendly, functional language inspired by Richard's love of Elm. Roc takes many of Elm's ideas beyond the frontend and introduces some great ideas of its own. Get ready to learn about static dispatch, platforms vs applications, opportunistic mutation, purity inference, and a whole lot more.
