Glauber Costa, co-founder and CEO of Turso, joins us to discuss libSQL, Limbo, and how they’re rewriting SQLite in Rust. We discuss their efforts with libSQL, the challenge of SQLite being in the public domain but not being open for contribution, their choice to rewrite everything with Limbo, how this all plays into the future of the Turso platform, how they test Limbo with Deterministic Simulation Testing (DST), and their plan to replace SQLite.

We seem to be experiencing a surge of video generation tools, models, and applications. However, video generation models generally struggle with some basic physics, like realistic walking motion. This leaves some generated videos lacking true motion with disappointing, simplistic panning camera views. Genmo is focused on the motion side of video generation and has released some of the best open models. Paras joins us to discuss video generation and their journey at Genmo.

Ashley Jeffs shares his journey with Benthos, an open source stream processor that was acquired by Redpanda. We talk about the evolution of data streaming technologies, the challenges he faced while growing the project, the decision to bootstrap versus seek venture capital, and what ultimately led to the acquisition. We discuss reactions to licensing changes, what it’s like to have your thing acquired, the challenging yet fulfilling nature of open source work, what’s next for Benthos, and what it takes to enjoy the journey.

M.G. Siegler goes way out on a limb with some BIG predictions of things that could happen this year, Simon Willison’s year-end roundup is a must-read and perhaps the only thing you have to read to get up-to-speed on the state of the LLM, Allen Pike describes a method for magic, Tom Critchlow thinks small databases are magic & James Stanier agrees with me about Parkinson’s Law and the usefulness of deadlines.

Our 7th annual year-end wrap-up is here! We’re featuring 12 listener voicemails, dope Breakmaster Cylinder remixes & our favorite episodes of the year. Thanks for listening! 💚

Justin & Autumn get together one last time for a retro: favorite episodes, lessons learned, biggest surprises & what’s next.

Daniel and Chris groove with Jeff Smith, Founder and CEO at CHRP.ai. Jeff describes how CHRP anonymously analyzes emotional wellness data, derived from employees’ music preferences, giving HR leaders actionable insights to improve productivity, retention, and overall morale. By monitoring key trends and identifying shifts in emotional health across teams, CHRP.ai enables proactive decisions to ensure employees feel supported and engaged.

Mitchell Hashimoto joins the show to discuss Ghostty, the newest terminal in town. Mitchell co-founded HashiCorp, took it all the way to IPO, exited in 2023—and now he’s working on a terminal emulator called Ghostty. Ghostty is set to 1.0 this month, so we sat down to talk through all the details.

Mat gathers the entire cast (sans Natalie, sadly) alongside our producer, Jerod Santo, for one last Go Time. That’s right, this is Go Time’s finale episode. After eight years and 340 episodes, we are going out on top. Join us one last time, you won’t regret it!

We share our feelings, reminisce on the good times, list some of our favorite moments & share a few opinions, which may (or may not) be unpopular. 😉

This episodes diverges from our traditional fare. I’ve reviewed the 50 previous editions and picked (IMHO) the coolest code, best prose & my favorite podcast episode from each month!

With so many great programming languages having emerged in the last decade, many of them purpose-built, when and where does Go still make sense and how do you make the case for it at work?

We’re making some big Changelog changes in 2025, the previously featured Stanford study on ghost engineers doesn’t live up to the hype, Git ingest is a simple service that turns any GitHub repository into a simple text ingest of its codebase, Simon Willison dishes out some hard-earned wisdom he acquired by working at Lanyrd / Eventbrite & Matheus Lima warns us about six mistakes that new managers make.

Alex from Kyutai joins us in this episode to discuss the research lab, their recent Moshi models, and what might be coming next from the lab. Along the way we discuss small models and the AI ecosystem in France.
