Ep. #6, Async Runtime For Rust with Carl Lerche of Tokio

On episode 30 of Open Source Ready, Brian Douglas and John McBride sit down with Felipe Huici to explore Unikraft and the growing role of unikernels in modern cloud infrastructure. They discuss how unikernels differ from containers and traditional virtual machines, why millisecond startup times matter, and how Unikraft enables secure, scale-to-zero workloads. The conversation also touches on Kubernetes integration, open source governance, and where cloud isolation is headed next.

On episode 6 of High Leverage, Joe Ruscio sits down with Carl Lerche, Principal Engineer at AWS and creator of Tokio. Carl shares his journey from Ruby and Rails into Rust, and explains why memory safety, fearless concurrency, and async runtimes matter for modern infrastructure. The conversation dives deep into the origins of Tokio, lessons from building foundational open source software, and how Rust’s guarantees are shaping the future of systems engineering.Want 10% off your ticket to TokioConf?

On episode 51 of Generationship, Rachel Chalmers sits down with Soya Park of Akify to explore why an organization’s most valuable knowledge rarely makes it into formal systems. They discuss how leaders make excellent decisions every day without realizing it, and how AI can surface, reinforce, and scale those best practices without disrupting existing workflows.

On episode 29 of Open Source Ready, Brian Douglas and John McBride sit down with Cameron Foxly to talk about ASCII Motion, an open source tool for creating animated ASCII art. Cameron shares how a brand design challenge at GitHub led to his first open source project and how AI tools helped him move from idea to production quickly. The conversation explores developer delight, terminal design, and why taste still matters in an AI-powered world.

On episode 88 of o11ycast, Ken Rimple and Jessica Kerr speak with Charity Majors about the shifting role of observability in modern software development. From AI-assisted instrumentation to reducing developer cognitive load, the episode examines how teams can move from reactive monitoring to continuous learning. It’s a deep dive into observability as a sense-making practice, not just a tooling problem.

On episode 6 of Data Renegades, CL Kao and Dori Wilson speak with Roger Magoulas about the real bottlenecks holding data organizations back. From the origins of “big data” to today’s explosion of tools and pipelines, the conversation focuses on why understanding, semantics, and communication matter more than ever. The episode is a call to shift from constant firefighting toward curiosity-driven insight.

On episode 5 of Data Renegades, CL Kao and Dori Wilson sit down with Benn Stancil to explore how data tools evolve, and sometimes lose their identity. Benn shares lessons from building Mode, the risks of drifting from an opinionated product vision, and why most companies struggle to turn data into meaningful decisions. The conversation also dives into the future of BI in a world increasingly shaped by AI and unstructured data.

On episode 48 of The Kubelist Podcast, Marc Campbell and Benjie De Groot sit down with Justin Cappos, professor at NYU and a pioneer in software supply chain security. They explore the origins of modern package manager security, the real-world limits of SBOMs, and why systems should be designed assuming compromise. The conversation spans CNCF governance, in-toto, TUF, Git security, and the emerging role of AI in securing software.

On episode 87 of o11ycast, Ken Rimple and Jessica Kerr sit down with Lada Kesseler to explore how experienced engineers can work effectively with AI coding assistants. They discuss why AI feels like a fast, noisy black box, and how patterns like semantic zooming, feedback loops, testing, and observability can help developers stay in control. This episode is a deep dive into using AI without sacrificing clarity, quality, or trust.

On episode 28 of Open Source Ready, Brian Douglas and John McBride reflect on the biggest themes that shaped open source and AI in 2025. From sustainability and security to MCPs, agents, and infrastructure, they revisit key conversations with guests and unpack how the industry evolved over the year. The episode closes with bold predictions for what 2026 may bring for developers, maintainers, and open source communities.
