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.

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?

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.

Our 6th annual year-end wrap-up episode! This time we're featuring 12 (yes, 12!) listener voice mails, our favorite episodes of the year & some insanely cool Breakmaster Cylinder beats made just for this occasion. Thanks for listening! 💚

This week we’re taking you to the hallway track of All Things Open 2023 in Raleigh, NC. Today’s episode features: Heikki Linnakangas (Co-founder of Neon and Postgres hacker), Robert Aboukhalil (Bioinformatics software engineer) working on bringing desktop apps to the web with Wasm, and Scott Ford who loves taking a codebase from brown to green at Corgibytes.

This week on The Changelog we're joined by Drew DeVault, talking about the Hare programming language. From the website, Hare is a systems programming language designed to be simple, stable, and robust. When we asked Drew why he created it, he said "[because] I wanted it to exist, and it did not exist." Wise words. We discuss Hare (of course), why he's so passionate about all things open source, the state of the language, fostering a culture that values stability, and oddly enough — what it takes to make a peanut butter and jelly sandwich.

This week we're gleaming the KubeCon. Ok, some people say CubeCon, while others say KubeCon...we talk with Solomon Hykes about all things Dagger, Tammer Saleh and James McShane about going beyond cloud native with SuperOrbital, and Steve Francis and Spencer Smith about the state of Talos Linux and what they're working on at Sidero Labs.

This week on we're joined by Emil Sjölander from Figma — talking about bringing Dev Mode to Figma. Dev Mode is their new workspace in Figma that's designed to bring developers and design to the same tool. The question they're trying to answer is "How do you create a home for developers in a design tool?" We go way back to Emil's startup that was acquired by Figma called Visly, how we iterated to here from 20 years ago (think PSD > HTML days), what they did to build Dev Mode, what they're doing around codegen, the popularity of design systems, and what it takes to go from zero to Dev Mode.

This week we're talking about Swift with Ben Cohen, the Swift Team Manager at Apple. We caught up with Ben while at KubeCon last week. Ben takes us into the world of Swift, from Apple Native apps on iOS and macOS, to the Swift Server Workgroup for developing and deploying server side applications, to the Swift extension for VS Code, Swift as a safe C/C++ successor language, Swift on Linux and Windows, and of course what The Browser Company's Arc browser is doing to bring Arc to Windows.

This week we’re talking with Cory Doctorow (this episode contains explicit language) about how we can get back to that "new good internet." Cory's new book The Internet Con offers a lens to this conversation about disenshittifying the internet through anti-trust laws, limits on corporate tweaking, regulating unconstrained capitalism, and all the ways enshittification is enabled. Cory also shares his experience recording his own audio book under the direction of Gabrielle de Cuir at Skyboat Media, and what's to come from his next Science Fiction book The Lost Cause.

Jean Yang's research on programming languages at Carnegie Mellon led her to realize that APIs are *the* layer that makes or breaks quality software systems. Unfortunately, developers are underserved by tools for dealing with, securing & understanding APIs. That realization led her to found Akita Software, which led her to join Postman by way of acquisition. That move, at least in part, also led her to join us on this very podcast. We think you're going to enjoy this interview, we sure did.

This week we’re taking you to the hallway track of All Things Open 2023 in Raleigh, NC. Today’s episode features: Matthew Sanabria (former Engineer at HashiCorp working on Terraform Enterprise), Nithya Ruff (Chief Open Source Officer and Head of the Open Source Program Office at Amazon) & Jordan Harband (Open Source Maintainer-at-large with dependencies in most JavaScript apps out there. There has been many changes this year in open source, and each of these perspectives lends insight into challenging and changing waters happening right now in open source.

Listen to our Next Level album as a podcast! We grew up in the days of the Nintendo Entertainment System and the Sega Genesis. It's no surprise that so many of our tracks are inspired by the 8-bit and 16-bit music of our youth. From Castlevania to Contra, Sonic the Hedgehog, and many more — we were inspired by all the nostalgic soundtracks from the games that got us here, to give our pods one-of-a-kind vibes. If you've been head nodding to our beats during our shows and you've been wishing for a way to listen outside of our pods, then this release will be an absolute delight. It's dangerous to go alone! Take this on your next coding adventure or deep work session...

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.

This week Jerod goes solo with Philipp Heckel, creator of ntfy, to discuss this simple HTTP-based service that lets you send notifications to your phone or desktop via scripts from any computer. They discuss why he built it, how he built it, and what his plans are for the future of this beloved side hustle.

This week we're joined by Marcin Kulik to talk about his project asciinema. You've likely seen this out there in the wild — asciinema lets you record and share your terminal sessions in full fidelity. Forget screen recording apps that offer blurry video. asciinema provides a lightweight, text-based approach to terminal recording with lots of possibilities. Marcin shares the backstory on this project, where he'd like to take it, who's supporting him along the way, and we even included 11 minutes of bonus content for Changelog ++ subscribers.

This week we're joined by Daniel Thompson, Co-founder and Core Member of Tauri. It's been a year since we last had Daniel on the show. He catches us up on all things Tauri, their continued efforts towards Tauri 1.5 (which just released), the launch of CrabNebula and how they're the people pushing the Tauri ecosystem forward and building on top of it, the state of Electron vs Tauri, and UI with Tauri. He even surprises us with his idea of creating a web browser.

This week we're taking you to the hallway track of the final Strange Loop conference. First up is AnnMarie Thomas — an engineering, business, and education professor. AnnMarie gave one of the opening keynotes titled "Playing with Engineering." We also caught up with many first-time and multi-time attendees who shared their favorite moments from Strange Loop over the years. You'll hear from Richard Feldman, Colin Dean, and Taylor Troesh. Last up we talk with Pokey Rule. He gave a talk about his project called Cursorless which is a spoken language for structural code editing. Changelog++ subscribers get a super extended version of this episode which includes everything we recorded at Strange Loop. Become a Changelog++ subscriber

This week we're joined by Steve O'Grady, Principal Analyst & Co-founder at RedMonk. The topic today is the definition of open source, the constant pressure on the true definition of the term, and the seemingly small but vocal minority that aim to protect that definition. In Steve's post _Why Open Source Matters_, he says "open source is at a crossroads" and there are some seeking to break the definition of open source to one that is more permissive to their desires, and they are closer than ever to achieving that goal. Today's conversation goes deep on this subject.

This week we're joined by Haroon Meer from Thinkst — the makers of Canary and Canary Tokens. Haroon walks us through a network getting compromised, what it takes to deploy a Canary on your network, how they maintain low false-positive numbers, their thoughts and principles on building their business (major wisdom shared!), and how a Canary helps surface network attacks in real time.

This week we're talking about the launch of OpenTF and what it's going to take to successfully fork HashiCorp's Terraform. We're joined by Josh Padnick to discuss what exactly happened, how HashiCorp's license change changes things, who has been impacted by this change, and ultimately what they are doing about it.

This week on The Changelog Adam is joined by Zach Lloyd, Founder & CEO of Warp. We talked with Zach last year about what it takes to build the terminal of the future, and today Adam catches up with Zach to see where they are at on that mission. They talk about the business model of Warp, how they measure success, reaching product/market fit, building features developers love, integrating AI, and the pros and cons of going open source (again).

This week we're talking to Andreas Kling about SerenityOS and Ladybird. Andreas started SerenityOS as a means of therapy. It's self-described as a love letter to "'90s user interfaces with a custom Unix-like core." Andreas previously worked at Nokia and later at Apple on the WebKit team, so he had an itch to do something along the lines of a browser, and that's where Ladybird came from. We get into the details of compilers, OSs, browsers, web specifications, and the love of making software.

This week we're talking with Jonathan Carter who's on his fourth term as Debian Project Lead (DPL) and we're talking about 30 years of Debian!

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.

Leslie Lamport is a computer scientist & mathematician who won ACM's Turing Award in 2013 for his fundamental contributions to the theory and practice of distributed and concurrent systems. He also created LaTeX and TLA+, a high-level language for "writing down the ideas that go into the program before you do any coding."

This week Adam is joined by Abi Noda, founder and CEO of DX to talk about DX AKA DevEx (or the long-form Developer Experience). Since the dawn of software development there has been this push to understand what makes software teams efficient, but more importantly what does it take to understand developer productivity? That's what Abi has been focused on for the better part of the last 8 years of his career. He started a company called Pull Panda that was acquired by GitHub, spent a few years there on this problem before going out on his own to start DX which helps startups to the fortune 500 companies gather real insights that leads to real improvement.

This week we're joined by Solomon Hykes, the creator of Docker. Now he's back with his next big thing called Dagger — CI/CD as code that runs anywhere. We're users of Dagger so check out our codebase if you want to see how it works. On today's show Solomon takes us back to the days of Docker, what it was like on that 10 year journey, his transition from Docker to Dagger, Dagger's community-led growth model, their focus on open source and community, how it works, and even a cameo from Kelsey Hightower to explain how Dagger works.

This week it's storytime with Steve Yegge! Steve came out of retirement to join Sourcegraph as Head of Engineering. Their next frontier is Cody, their AI coding assistant that answers code questions and writes code for you by reading your entire codebase and the code graph. But, we really spent a lot of time talking with Steve about his time at Amazon, Google, and Grab. Ok, it's storytime!

This week we're talking about type checking with Jake Zimmerman. Jake is one of the leads at Stripe working on Sorbet — an open source project that does Type checking in Ruby and runs over Stripe's entire Ruby codebase. As of May of 2022 Stripe's codebase was over 15 million lines of code spread across 150,000 files. If you think you have a bigger Ruby codebase, Jake is down to go byte-for-byte to see who wins. Jake shares tons of wisdom and more importantly he shares why he thinks types will win in the end.

This week we're talking to Daniel J. Barrett, author of Efficient Linux at the Command Line as well as many other books. Daniel has a PhD and has been teaching and writing about Linux for more than 30 years (almost 40!). So we invited Dan to join us on the show to talk about efficient ways to use Linux. He teaches us about combining commands, re-running commands, $CDPATH hacks, and more.

Taylor Troesh joins Jerod to discuss a bevy of software development topics: yak shaves, dependency selection, -10x engineers, IKEA-oriented development, his new content-addressable programming language & much more along the way.

This week we're joined by Adam Jacob and we're talking about his mission at System Initiative to rebuild DevOps. They are out of stealth mode and ready to show off their transformative new power tool that reimagines what's possible from DevOps. It's an intelligent automation platform that allows DevOps teams to build detailed interactive simulations of their infrastructure and use them to rapidly update their production environments.

This week we're talking about Passkeys with Anna Pobletts, Head of Passwordless, at 1Password. Will Passkeys enable a passwordless future? Time will tell. Anna shares the what, the why, how, and the when on Passkeys.

This is our last week of hallway track coverage at The Linux Foundation's Open Source Summit North America 2023 in Vancouver, Canada. Today’s anthology episode features: Jeffrey Sica (Developer Experience & Programs @ CNCF), Eddie Zaneski (Kubernetes SIG CLI), Yaron Schneider (Co-creator of Dapr and Founder and CTO at Diagrid). Special thanks to our friends at GitHub for sponsoring us to attend this conference as part of Maintainer Month.

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.

This week on The Changelog we're continuing our Maintainer Month series by taking to you back to the hallway track of The Linux Foundation's Open Source Summit North America 2023 in Vancouver, Canada. Today’s anthology episode features: Stormy Peters (VP of Communities at GitHub), Dr. Dawn Foster (Director of Open Source Community Strategy at VMware), and Angie Byron (Drupal Core Product Manager and Community Director at Aiven). Special thanks to our friends at GitHub for sponsoring us to attend this conference as part of Maintainer Month.

This week on The Changelog we're taking you to the hallway track of The Linux Foundation's Open Source Summit North America 2023 in Vancouver, Canada. Today’s anthology episode features: Beyang Liu (Co-founder and CTO at Sourcegraph), Denny Lee (Developer Advocate at Databricks), and Stella Biderman (Executive Director and Head of Research at EleutherAI). Special thanks to our friends at GitHub for sponsoring us to attend this conference as part of Maintainer Month.

This week Sarah Drasner joins us to talk about her book Engineering Management for the Rest of Us and her experience leading engineering at Zillow, Microsoft, Netlify, and now Google.

This week we're celebrating Maintainer Month along with our friends at GitHub. Open source runs the world, but who runs open source? Maintainers. Open source maintainers are behind the software we use everyday, but they don't always have the community or support they need. That's why we're celebrating open source maintainers during the month of May. Today's conversation features Alyssa Wright (Bloomberg), Chad Whitacre (Sentry), and Duane O’Brien (Creator of the FOSS Contributor Fund and framework). We get into all the details, the why, the hows, and the struggles involved for companies to support open source.

José Valim joins Jerod to talk all about what's new in Livebook – the Elixir-based interactive code notebook he's been working on the last few years. José made a big bet when he decided to bring machine learning to Elixir. That bet is now paying off with amazing new capabilities such as building and deploying a Whisper-based chat app to Hugging Face in just 15 minutes. José demoed that and much more during Livebook's first-ever launch week. Let's get into it.

This week Adam talks with Andy Klein from Backblaze about hard drive reliability at scale.

This week we're joined by Zach Latta, the Founder of Hack Club. At 16, Zach tested out of high school and moved to SF to join Yo as their first engineer. After playing a key role at Yo, he founded Hack Club to help teen hackers start coding clubs around the world. Today, teen hackers can meet IRL, online, at a hackathon, or leverage Hack Club Bank a fiscal sponsor to create their own organization. Hack Club is the program Zach wished he had in high school.

This week we're talking with Cory Doctorow (this episode contains explicit language) about his newest book Chokepoint Capitalism, which he co-autored with Rebecca Giblin. Chokepoint Capitalism is about how big tech and big content have captured creative labor markets and the ways we can win them back. We talk about chokepoints creating chickenized reverse-centaurs, paying for your robot boss (think Uber, Doordash, Amazon Drivers), the chickenization that's climbing the priviledge gradient from the most blue collar workers to the middle-class. There are chokepoints in open source, AI generative art, interoperability, music, film, and media. To quote Cory, "We're all fighting the same fight."

This week we're talking about LLMs with Simon Willison. We can not avoid this topic. Last time it was Stable Diffusion breaking the internet. This time it's LLMs breaking the internet. Large Language Models, ChatGPT, Bard, Claude, Bing, GitHub Copilot X, Cody...we cover it all.

After years of working for Google on the Go Team, Filippo Valsorda quit last year to experiment with more sustainable paths for open source maintainers. Good news, it worked! Filippo is now a full-time open source maintainer and he joins Jerod on this episode to tell everyone _exactly_ how he's making the equivalent to his total compensation package at Google in open source.

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.

This week we're talking with Georgi Gerganov about his work on Whisper.cpp and llama.cpp. Georgi first crossed our radar with whisper.cpp, his port of OpenAI’s Whisper model in C and C++. Whisper is a speech recognition model enabling audio transcription and translation. Something we're paying close attention to here at Changelog, for obvious reasons. Between the invite and the show's recording, he had a new hit project on his hands: llama.cpp. This is a port of Facebook’s LLaMA model in C and C++. Whisper.cpp made a splash, but llama.cpp is growing in GitHub stars faster than Stable Diffusion did, which was a rocket ship itself.

This week we're talking with Nathan Sobo about his next big thing. Nathan is known for his work on the Atom editor while at GitHub. But his work wasn't finished when he left, so...he started Zed, a high-performance multiplayer editor that's engineered for performance. And today, Nathan talks us through all the details.

This week Adam talks with Marcin Kurc about chasing the 9s. Marcin is the Co-founder and CEO of Nobl9 where they build tools for managing service level objectives, aka SLOs. We also talk about service level agreements (SLAs), service level indicators (SLIs), error budgets, and monitoring, and how it all comes together to help teams align on goals, improve customer satisfaction, manage risks, increase transparency, and of course, a favorite around here...continuous improvement. Kaizen! This is an awesome deep dive into the world of chasing those 9s, and how teams are levering SLOs to earn the trust of their customers as well showcase transparency.
