Cilium, eBPF, and Modern Kubernetes Networking with Bill Mulligan

Modern cloud-native systems are built on highly dynamic, distributed infrastructure where containers spin up and down constantly, services communicate across clusters, and traditional networking assumptions break down. Linux networking was designed decades ago around static IPs and linear rule processing, which makes it increasingly difficult to achieve scale in Kubernetes environments. At the same time, modifying the Linux kernel to keep up with these demands is slow, risky, and impractical for most organizations. The Extended Berkeley Packet Filter, or eBPF, is a Linux kernel technology that allows sandboxed programs to run safely inside the kernel without modifying kernel source code or loading kernel modules. Cilium is an open-source, cloud-native networking platform that’s built on eBPF, and provides, secures, and observes connectivity between workloads in Kubernetes and other distributed environments. Bill Mulligan is a maintainer in the Cilium ecosystem and a member of the team at Isovalent, the company behind Cilium. He joins the show with Gregor Vand to discuss how eBPF works under the hood, why Cilium has become one of the most widely adopted Kubernetes networking projects, and how the future of cloud-native infrastructure is being reshaped by programmable kernels. Gregor Vand is a security-focused technologist, having previously been a CTO across cybersecurity, cyber insurance and general software engineering companies.

Games That Push Back with Bennett Foddy

Bennett Foddy is a legendary game designer known for creating wholly distinctive games such as QWOP, Getting Over It with Bennett Foddy, and the recently released Baby Steps. He’s also a former professor at the NYU Game Center, where he taught game design alongside developing his own experimental work. In this episode, Bennett joins Joe Nash to discuss his systems-driven approach to game design, why frustration and difficulty are often misunderstood, how streaming and speedrunning have reshaped how games are played and experienced, and what makes his games stand out.

Prettier and Opinionated Code Formatting with James Long

Developer tooling shapes how software gets written day to day, but the best tools often disappear into the background once they succeed. Formatting, linting, and build systems can either create friction and endless debate, or quietly remove entire classes of problems from a team’s workflow. Over the past decade, the JavaScript ecosystem has wrestled with both extremes as it scaled rapidly and accumulated complexity. Prettier emerged as a response to the surprisingly human problem of engineers spending too much time debating code style instead of building software. It offers a deterministic, opinionated formatter that helped normalize automation as part of everyday development. James Long is a design and product engineer who has worked at Mozilla and Stripe, and he’s the creator of Prettier. He joins the show with Josh Goldberg to talk about the origins of Prettier, why formatting debates are so emotionally charged, the technical challenges of building formatters, the realities of maintaining popular open-source tools, and how the JavaScript tooling ecosystem continues to evolve. Josh Goldberg is an independent full time open source developer in the TypeScript ecosystem. He works on projects that help developers write better TypeScript more easily, most notably on typescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code. Josh regularly contributes to open source projects in the ecosystem such as ESLint and TypeScript. Josh is a Microsoft MVP for developer technologies and the author of the acclaimed Learning TypeScript (O’Reilly), a cherished resource for any developer seeking to learn TypeScript without any prior experience outside of JavaScript. Josh regularly presents talks and workshops at bootcamps, conferences, and meetups to share knowledge on TypeScript, static analysis, open source, and general frontend and web development.

Skate Story with Sam Eng

Skateboarding games have long balanced technical precision with a sense of flow and expression, but Skate Story takes the genre in a radically different direction. It has a distinct vaporwave vibe and blends fluid skate mechanics with exploration, puzzles, and an existential narrative about freedom, pain, and obsession. The game was created by indie developer Sam Eng, who previously released Zarvot for the Nintendo Switch. Skate Story launched to critical acclaim and was widely regarded as one of the best games of 2025. In this episode, Sam joins the show with Joe Nash to talk about developing Skate Story.

DeepMind’s RAG System with Animesh Chatterji and Ivan Solovyev

Retrieval-augmented generation, or RAG, has become a foundational approach to building production AI systems. However, deploying RAG in practice can be complex and costly. Developers typically have to manage vector databases, chunking strategies, embedding models, and indexing infrastructure. Designing effective RAG systems is also a moving target, as techniques and best practices evolve in step with rapidly advancing language models. Google DeepMind recently released the File Search Tool, a fully managed RAG system built directly into the Gemini API. File Search abstracts away the retrieval pipeline, allowing developers to upload documents, code, and other text data, automatically generate embeddings, and query their knowledge base. We wanted to understand how the DeepMind team designed a general-purpose RAG system that maintains high retrieval quality. Animesh Chatterji is a Software Engineer at Google DeepMind and Ivan Solovyev is a Product Manager at DeepMind, and they worked on File Search Tool. They joined the podcast with Sean Falconer to discuss the evolution of RAG, why simplicity and pricing transparency matter, how embedding models have improved retrieval quality, the tradeoffs between configurability and ease of use, and what’s next for multimodal retrieval across text, images, and beyond. Sean’s been an academic, startup founder, and Googler. He has published works covering a wide range of topics from AI to quantum computing. Currently, Sean is an AI Entrepreneur in Residence at Confluent where he works on AI strategy and thought leadership. You can connect with Sean on LinkedIn.
