The GitHub Podcast

Cassidy and GPS welcome GitHub VP of Developer Relations (and original GitHub Podcast host) Martin Woodward. Martin reflects on attending every Universe since its earliest days, then digs into what he calls one of the trickiest open problems facing GitHub right now: as AI makes it dramatically easier to generate a pull request, open source maintainers are being flooded with well-meaning but low-effort contributions. He also goes deep on this year’s Universe conference badge, now with an accelerometer that auto-flips the screen, capacitive PCB game controls, and a Copilot agent that can write and deploy MicroPython apps straight to the badge from a single prompt. Martin shares his advice for staying curious and giving yourself “permission to play” in a career that spans multiple tech epochs, and why he thinks the fundamentals worth learning now are less about which language you pick and more about systems thinking. They wrap with three open source picks: ZoomIt for Mac, prek, and Martin’s own Halloween-ready PumpkinPi and IKEA OBEGRÄNSAD lamp hack.Links mentioned in the episode:GitHub UniverseLearn to CloudPimoroni Tufty badgeZoomIt for MacprekPumpkinPiIKEA OBEGRÄNSAD ESP32 hack The GitHub Podcast is produced and edited by editaudio.

Cassidy and Andrea are joined by Sameen Karim, Senior Product Manager at GitHub, to dig into stacked pull requests, GitHub's newly launched (and long-requested) way to break large changes into a linked chain of small, reviewable PRs. Sameen pulls back the curtain on just how deep this went: every time a PR updates, GitHub runs a live "ghost merge" simulation behind the scenes to check whether it's mergeable, and stacking meant multiplying that complexity across up to 100 linked PRs at once. The team had to rethink core assumptions about how a PR's base branch relates to its actual merge target, rewrite parts of the merge box that hadn't been touched in over a decade, build an entirely new asynchronous merge path, and close a code owners loophole that could otherwise let people sneak changes past review. Sameen also talks about "agent-driven testing," where GitHub ran swarms of agents around the clock trying to break the feature, how teams like Vercel, Nuxt, and the React team are already adopting stacks, and what's next: support for stacks across forks. The episode closes with three open source picks: Sarah Drasner's visual code explainers, the AGENTS.md standard, and the open source gh-stack CLI Sameen built (and rewrote in Go) to manage stacks locally.Links mentioned in the episode:GitHub UniverseSarah Drasner's code drawingsAGENTS.mdgh-stack CLI The GitHub Podcast is produced and edited by editaudio.

Cassidy and GPS are joined by Camilla Moraes, a product manager on GitHub's Maintainer Love (aka Tiny Wins) team, to talk about how the team finds and ships small, high-impact fixes for open source maintainers. Camilla walks through her path from engineering to product, and shares how the team's focus shifted this year from quick two-to-three-week "paper cuts" to a bigger, all-hands problem: the rise of low-quality, AI-generated contributions flooding repos. Camilla gives some insight into a new tool the Tiny Wins team has designed to address that issue: PR limits, which lets maintainers cap how many open PRs a user without write access can have at once. The group also talks through how the team prioritizes an endless stream of feedback from Slack, socials, and surveys, and how Camilla built her own repo-as-a-database system with Copilot to track it all. They close out with three open source picks: iOpenPod, Bento, and Camilla's own vibe-coded project for rating the health of a GitHub repo.Links mentioned in the episode:Maintainer CommunityiOpenPodBento  The GitHub Podcast is produced and edited by editaudio.

Cassidy and GPS dive into a round of AI hot takes to separate the extreme, engagement-bait opinions from the actual nuance. They debate whether developers still need to read AI-generated code, why “jobs won't hire you if you don't use AI” is more complicated than it sounds, and GPS's own hot take against the newest wave of paid coding bootcamps. From there they tackle whether skills have killed MCP, whether RAG is dead, and a borrowed hot take from their boss Martin: if you have to fine-tune a model to your code base, your code is bad. They close out with two open source picks: Pollinations AI, a generative AI platform experimenting with earning credits through code contributions, and Avian Visitors, a beautifully documented build log of a bird-listening e-ink display.

In today’s episode, Cassidy, Marlene, and GPS tackle the ever-growing pile of new AI and agent terminology that's popped up seemingly overnight. They break down loop engineering (designing systems that prompt your agents instead of prompting them yourself), the Ralph loop that helped popularize it, and how squads and fleets let multiple agents split up planning, testing, and review work in parallel. They also dig into harness engineering (the scaffolding around a model that turns raw text generation into something useful), the newly coined “hill climbing,” and why forward deployed engineer might just be a solutions architect with better AI tooling. They wrap with a look at the spectrum between closed, open weight, and open source models, plus each host's open source pick of the week: Astro 7, the RAE API project, and Tau.
