    Protocol Shorts: MITM Proxies and Transparent L4 Interception

    episode 31 — Protocol Shorts: MITM Proxies and Transparent L4 Interception. In this second "Protocol Shorts" episode, we look at man-in-the-middle proxies from the transport layer up. The episode explains how HTTP proxies, HTTP CONNECT, and SOCKS5 differ, why they all assume a proxy-aware client, and what changes when a transparent layer 4 proxy is inserted by the operating system instead. From there, we dig into protocol detection from the first bytes on the wire and into the BridgeIo abstraction in Rama: a way to relay and inspect stacked handshakes incrementally instead of terminating every protocol upfront.

    socketioxide with Théodore Prévot

    episode 28: socketioxide with Théodore Prévot. This episode features an in-depth conversation with Théodore Prévot, creator and maintainer of the Rust crate socketioxide. We explore the origins of the project, how a personal writing app led to implementing a full Socket.IO server in Rust, and what it takes to build and maintain a high-level real-time protocol on top of Tokio, Tower, and the Rust HTTP ecosystem. Théodore walks us through the layered architecture of Engine.IO and Socket.IO, explains concepts like rooms, namespaces, acknowledgements, adapters, and connection recovery, and reflects on protocol versioning and compatibility challenges. We also dive into one of the hardest technical problems behind socketioxide: building a custom lazy JSON deserializer wrapper around Serde to efficiently route and decode mixed JSON and binary payloads. Finally, we discuss abstraction boundaries, async runtime considerations, integration testing strategies, the possibility of a Rust client implementation, and what motivates long-term open source maintenance.

    AI Policies, OSS Maintenance and EU Open Source Academy with Daniel Stenberg

    episode 27: AI Policies, OSS Maintenance and EU Open Source Academy with Daniel Stenberg. This episode features a deep and pragmatic conversation with Daniel Stenberg, founder of cURL and president of the European Open Source Academy, reflecting on FOSDEM 2026, the growing role of open source in European policy, and what digital sovereignty means in practice; Daniel shares the motivation behind the EU funded Open Source Academy, discusses how maintainers are dealing with the rise of AI generated security reports, explains why cURL shut down its bug bounty program, and offers a balanced view on where LLM tools genuinely help in code review and security research versus where they create noise, all while highlighting the long term realities of maintaining critical infrastructure software for decades.

    Email protocols with Mauro De Gennaro from Stalwart Labs

    episode 26: Email protocols with Mauro De Gennaro from Stalwart Labs. This episode features an in depth conversation with Mauro De Gennaro of Stalwart Labs that demystifies how email actually works in practice, from SMTP delivery and DNS based routing to IMAP, JMAP, spam filtering, encryption, and authentication standards like DKIM, SPF, and DMARC, all through the lens of building and operating a modern mail and collaboration server in Rust; Mauro shares his long personal journey from early BBS systems to founding Stalwart, explains why email protocols have evolved the way they have, how self hosting email can be practical and secure today, and why open standards, automation, and memory safety are key to reclaiming control over critical communication infrastructure.

    WebAssembly and Rust in Practice, A Conversation with Alex Crichton

    episode 24: WebAssembly and Rust in Practice, A Conversation with Alex Crichton. In this episode we sit down with Alex Crichton to talk about WebAssembly and Rust in practice. We discuss how Wasm grew beyond the browser into a serious runtime for servers and plugins, and why Rust fits so well in this space. We also explore WASI, the component model, and lessons from building Wasmtime, covering performance, security, and what it takes to run Wasm in production.
