Jay Faulkner sits down with Kevin (GitHub: canon92), Kubernetes Contributor Award winner and maintainer of the JobSet project, to discuss the growing challenge of running AI and batch workloads on Kubernetes — a platform originally designed for web services and long-running applications.
Kevin shares his journey from G Research and the Armada project through to his current work improving Kubernetes upstream, including the multi-year effort to bring swap memory support to GA, the push to deprecate CGroups v1, and the emerging Workload Aware Scheduling initiative aimed at bringing gang scheduling into Kubernetes core.

The conversation covers the technical realities of running GPU workloads at scale, the human side of open source maintenance, and the often overlooked work of keeping CI infrastructure healthy across a massive distributed project.

Topics discussed include JobSets, CGroups v2, pressure stall information, topology aware scheduling, and the open source politics of shipping features in a large community-driven project.

We sit down with Æva Black as she shares her journey from creating OpenStack Ironic to leading security policy at Microsoft and CISA. Discussion covers the economics of competing with hyperscalers, Europe's Cyber Resilience Act, managing software dependency complexity, AI's impact on security (including the rise of "vibe hackers"), and a powerful story about how a casual conference conversation led to influencing White House cybersecurity strategy.

In this episode of the G Research Open Source Software Outreach Podcast (GROSS OUT), host Jay Faulkner sits down with Dr. Dawn Foster, Director of Data Science at the CHAOSS Project and veteran open source consultant, to explore the hidden infrastructure that keeps open source communities thriving.

Dawn shares her 30-year journey through the open source world, from compiling dependencies as a sysadmin in the '90s to earning a PhD studying collaboration in the Linux kernel. The conversation dives deep into the metrics and governance structures that separate sustainable projects from those destined to fail—including the critical "lottery factor" (what happens when the most important person in your project disappears) and why you should build governance before you need it.

Alex Gaynor, long-time open source contributor and core developer of Django, PyPy, and Python's cryptography library, joins us to discuss the challenging transition from C to Rust in the Python ecosystem. We explore memory safety vulnerabilities like buffer overflows, the technical and community challenges of introducing Rust to a major Python library, and how to navigate hostile feedback during controversial changes. Alex shares lessons from shipping the first Rust-based cryptography release, managing platform compatibility issues, and why sometimes breaking backwards compatibility is necessary to move an ecosystem forward.

A must-listen for anyone maintaining critical open source infrastructure or dealing with the "gross" realities of pushing technological boundaries.

In this episode of the G Research Open Source Software Outreach Podcast, host Jay Faulkner sits down with Priyanka "Pinky" Ravi, Platform Tech Advocate at G Research, to explore her unique path from full-stack developer to open source advocate. Pinky shares her fascinating journey implementing inner source practices at State Farm, leading Kubernetes GitOps adoption, and eventually joining the team behind Flux at WeaveWorks. The conversation dives deep into what GitOps really means, the four core principles that define true GitOps, and how pull-based deployment models solve configuration drift. Along the way, they discuss the evolution of DevOps practices, the power of infrastructure as code, and why the CNCF ecosystem has become such a valuable community for both users and maintainers.

In this episode of the G-Research Open Source Software Outreach Podcast, we sit down with Tim Boudreau, one of the early members of G-Research's open source initiative. Tim shares his unique perspective on transitioning from 30 years of writing proprietary software to working in open source communities.

We explore the challenges of moving from the controlled environment of corporate development to the exposed world of public repositories, where your code is visible from day one. Tim discusses the psychological shifts required, from developing a thicker skin to handling rejection, and shares candid stories about both successful contributions and frustrating rejections from major open source projects.

The conversation covers practical advice for developers considering their first open source contributions, the importance of community engagement, and strategies for testing the waters before diving into major contributions. Tim also touches on his current work with NVIDIA's Big AI framework and how G-Research has evolved from having an insular and closed security posture to being an active participant in the open source ecosystem.
