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.
