Most developers use async runtimes.
Few know how they came to be—or why they’re needed.
On Netstack.FM 🎙️ Ep.34 (Remastered Ep.5), we revisit our conversation with Tokio creator @carllerche.com
Timed with #TokioConf (Apr 20–22, 2026): www.tokioconf.com

Even with HTTPS, your ISP or network could still see which sites you visit.
ECH is starting to reduce this—while changing how proxies and security systems work.
On Netstack.FM 🎙 Ep.33 we cover TLS Encrypted Client Hello. Listen at netstack.fm#episode-33
#tls #security #privacy #networking #devops
How do proxies behave when the client isn’t aware of them?
On Netstack.fm Ep.31 we cover MITM proxies, transparent L4 interception, and protocol detection from raw bytes.

We talk with Martin Algesten @algesten.bsky.social creator of the Rust HTTP client uReq.
We discuss why uReq was created, designing a synchronous HTTP client in Rust, implementing HTTP 1.1, and how uReq 3 adopted Sans-IO.

AI can scan code and review PRs.
It can also generate false positives and hard-to-verify security reports.
On netstack.fm Ep.27, Daniel Stenberg (curl) @daniel.haxx.se discusses AI in vulnerability reporting, EU open source policy, and sustaining long-term infrastructure.

🌐 Most software developers have configured email - SMTP creds, DNS records, IMAP quirks - but not always with a full view of how it all fits together.
On Netstack.FM Ep.26 we talk with Mauro De Gennaro from Stalwart Labs (stalw.art), who built a mail server in #Rust

WebAssembly ≠ just the browser.
On Netstack.FM Ep.24🎙️Alex Crichton (github.com/alexcrichton) explains:
* Wasm as a plugin & runtime platform
* WASI + components in real systems
* async without blocking hosts
* where Wasm actually fits today

Protocol Shorts #1 is live 🎙️
HTTP isn’t just request/response.
We talk:
*gRPC-web & browser limits
*Trailers, streams, failure signaling
*Tunneling via HTTP/2 & WebSockets
*Why HTTP/1, 2, and 3 still matter

🌐 “What is a URL?” sounds simple — until you implement one correctly.
On Netstack.FM Ep.22, Simon Sapin explains rust-url, WHATWG specs, Unicode, IDNA trade-offs, and why browsers and server view URLs differently.

Networking isn’t just about protocols — it’s about systems, people, and long-term thinking.
In Netstack.FM Ep.20 (New Year special), we reflect on lessons from conversations with maintainers of Tokio, Hyper, curl, QUIC, DNS, gRPC, and more.

On Ep. 19, we explore:
* virtual network adapters & routing
* DNS interception vs full tunnel VPNs
* NAT traversal, ICE, STUN/TURN
* why WireGuard’s simplicity matters
* how Zero Trust reshapes network design
A clear, engineering-focused exploration of modern VPN architecture.
#SystemsEngineering
Why do many VPNs still feel slow or intrusive for users?
Ever wondered how a VPN works at the packet level?
In Netstack.FM Ep.19, we talk with Thomas Eizinger (Firezone) about building a Zero Trust VPN on top of WireGuard at OSI layer 3.

In this Episode 18 we cover:
• Quake’s ~300ms latency limit
• client-side prediction in multiplayer
• ADB reliability at massive scale
• when to own your network stack
• writing & diagrams as learning tools

How do early systems shape modern software?
In Netstack.FM🎙️Ep.18, We talked with Fabien Sanglard
@fabinou.bsky.social about latency, Quake’s TCP/IP evolution, Android’s ADB, and Rust in large systems.
A reflective conversation on how systems actually work.

@williammorgan.me we would love that. Could you and/or the maintainer(s) in question please send an email to hello@netstack.fm (the email on the podcast's website). We can book you still in for December, or otherwise January! There's a lot to unpack there so we would love to nerd out on that one!
More from our conversation with Larry Masinter:
• early Gopher → Web transitions
• the #Interlisp revival
• lessons from early hypertext and standards work
• the thinking behind data URLs
• how collaboration shaped the modern Web
#InternetHistory #SoftwareEngineering #OpenStandards #TechPodcast
New on Netstack.FM Ep.17 with Larry Masinter, whose work shaped URLs, HTTP/1.1, MIME types, and the early Web.
We cover:
• resources vs representations
• why 418 exists
• IETF/W3C culture, and more
A rare firsthand look at someone who helped build the Internet’s foundations.

We also get into Rust’s role in protocol engineering and why Sans I/O keeps implementations clean, testable, and runtime-agnostic.
str0m splits media, DTLS, and ICE with zero internal I/O — a big win for real-time systems. If you’re into Rust + networking, you’ll enjoy this one.
#SystemsEngineering
WebRTC looks simple in browsers, but under the hood it’s a maze of 90s-era protocols, NAT quirks, encryption layers, and real-time constraints.
In this episode, Martin explains:
* why ICE isn’t “just hole punching”
* how DTLS negotiates SRTP keys
* why UDP is still king for real-time
#RealTimeMedia
On Netstack.FM🎙️Ep.16: A deep dive into #WebRTC & Sans I/O with Rust developer @algesten.bsky.social
We cover STUN/TURN, NAT traversal, SRTP/DTLS, RTC internals, why UDP matters, and how the #Rust WebRTC stack str0m runs in production. Curious how WebRTC works?
