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.

The GitHub Podcast is back for Season 2! In the season opener, Cassidy Williams is joined by co-hosts Marlene Mhangami and GPS Peña-Siguenza. The trio revisits their favorite moments from Season 1, including Keeley Hammond's take on Electron and why “bloated JavaScript” hot takes don't hold up, Angie Jones's conversation on MCP and Goose, and the Tiny Wins team's work fixing the everyday "paper cuts" that make life easier for open source maintainers. From there, the hosts dig into their own winding paths into tech. GPS’ shares her journey from sysadmin to .NET and Cloud Advocacy to building a free open source platform that teaches cloud fundamentals (now used by nearly 7,000 people). Marlene traces her path from studying molecular biology to becoming a fixture in the Python community, and her early open source work on CuDF at NVIDIA, advocating for Ibis at Voltron Data, then starting the LangChain Azure repository at Microsoft. Cassidy rounds out the episode with insights to her front-end and React roots and her early days making tech memes on TikTok. Finally, each host shares an open source pick of the week: Mediabunny, Handy, and Cua.

In this year-in-review episode of The GitHub Podcast, Cassidy and Abby are joined by Helen Hou-Sandí, GitHub’s engineering manager for the Accessibility Engineering team and lead developer in the WordPress project.

They dig into Maintainer Tiny Wins, a series of two week long timeboxed improvements that save millions of developer minutes a day, from smarter PR reviewers panels and one-click merge conflict resolution to long-awaited WebP support. Helen shares how accessibility issues often spark broader UX improvements, and why fixing “just” a border color can evolve into deeply impactful changes at GitHub’s scale. They also explore the rise of the Model Context Protocol (MCP) as an open standard, GitHub’s new open source accessibility scanner action, supporting non-code contributors and AI as the “over-eager new contributor.

Whether you’re a maintainer, a contributor, or just love a good Furby-powered keynote, this episode is a love letter to the tiny details that make open source better for everyone.

In this episode guest host Greg Cochran from the GitHub Secure Open Source Fund brings together four maintainers who are helping secure the open source projects we all depend on: Christian (Log4j/Log4Shell), Carlos (GoReleaser), Michael (EVCC), and Camila (ScanAPI) to unpack what it really looks like to level up security in critical OSS.

They share how the Fund’s three-week security sprint, ongoing check-ins, and tight-knit community helped them move from “we don’t know what we don’t know” to concrete wins: hardened GitHub Actions pipelines, incident response plans, better reporting processes, and SBOMs that actually include dependency licenses. They also talk candidly about asking “dumb” questions in a trusted space and the ripple effect when one project’s security posture improves across its dependents. Finally, the group dives into AI security: using fuzzing, GitHub Copilot, and tools like the Secure Code Game both to find vulnerabilities faster and to keep up with attackers who now have AI on their side too.

Abby sits down with Angie Jones, VP of Engineering at Block, live at GitHub Universe to talk about Goose, Block’s open source AI agent and reference implementation of the Model Context Protocol (MCP). Angie shares how Goose went from an internal tool to an open source project that lets the community drive features like multimodel support, and how Block’s 12,000 employees across 15+ job functions (not just engineers) now use agents every day. They dig into practical, non-hype uses of AI agents: detecting when students are struggling, triaging open source issues, segmenting 80k+ sales leads, and even letting a salesperson “vibe code” a feature on the train. Angie also talks about trust and control when giving AI access to codebases, why developers are tired of flashy demos, and how her new AI Builder Fellowship is designed to support the next generation of native AI builders.

In this episode, recorded live at GitHub Universe 2025, Andrea sits down with Frank “Frenck” Nijhof, a GitHub Star and project lead for Home Assistant, one of the most active open source projects on the platform. They unpack how millions of households run privacy-first automations locally (no cloud required), why the Open Home Foundation exists to prevent vendor lock-in and e-waste, and how this famously welcoming community scaled to 21k+ contributors. Frank also shares insights about the development of “Assist,” an open, local-first voice assistant (with optional AI), as well as the new “Home Assist Green” hardware device, plus practical ways non-coders can meaningfully contribute to the project, too.

Andrea and Kedasha sit down with data whisperer Jeff Luszcz, one of the wizards behind GitHub’s annual Octoverse report, to unpack this year’s biggest shifts. They get into why TypeScript overtook Python on GitHub, how AI-assisted “vibe coding” and agentic workflows are reshaping everyday engineering, and what it means that more than one new developer joins GitHub every second. From 1.12B open source contributions and 518M merged PRs to COBOL’s unexpected comeback, global growth (hello India, Brazil and Indonesia), and “security by default” with CodeQL and Dependabot, this episode turns the numbers into next steps for your career and your open source projects.

Homebrew’s project lead Mike McQuaid joins Abby and Andrea to unpack what it really takes to sustain one of the most-used developer tools on macOS and Linux. From early GitHub workflows to today’s automation and guardrails, Mike details the soft-power leadership that keeps volunteers motivated, and shares insights on how to scale contributions, keep a small maintainer team effective, and triage with empathy (and boundaries). This episode covers governance, “saying no,” using AI responsibly, and how IRL feedback at Universe turned into performance wins.

In this episode of the GitHub Podcast, Abby and Kedasha are joined by Keeley Hammond, a longtime maintainer of the Electron project. They explore the inner workings of one of the most widely used open source desktop frameworks, dive into how Electron empowers developers to build cross-platform desktop apps with web technologies, and discuss what it takes to build a welcoming and sustainable open source community at scale. The conversation touches on contributor culture, project governance, automation tools, and the role of AI in open source, in both its promise and its challenges.
