    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.

    Protocol Shorts: HTTP as an Application Bus

    episode 23 — Protocol Shorts: HTTP as an Application Bus. This is the debut of our "Protocol Shorts" series: fast-paced, high-density conversations with one or more expert guests centered around a common theme. In the "HTTP as an application bus" episode, we’re breaking down the tunneling renaissance—specifically the clever 'protocol-within-a-protocol' hacks that are changing the game. From hijacking H2 CONNECT to run full-duplex WebSockets, to the subtle ways we’re now nesting modern traffic inside older transports, we’re looking at how the network layer is being rewritten from the inside out.

    Firezone and Zero-Trust Network Security with Thomas Eizinger

    episode 19 — Firezone and Zero-Trust Network Security with Thomas Eizinger. In this episode of Netstack.fm, Glen talks with Thomas Eizinger from Firezone about designing a zero trust enterprise VPN built on top of WireGuard. They break down how modern VPNs work in practice, covering virtual network adapters, split tunneling, DNS interception, policy based access, and secure packet routing using WireGuard, ICE, and TURN relays. The discussion highlights how Firezone differs from legacy VPNs by focusing on performance, reliability, and minimal user friction, while also touching on the role of Rust and Elixir in Firezone’s architecture and the long term importance of IPv6 adoption.
