During the last year and a half, I wrote a book on server-side WebAssembly. Getting into Wasm is hard. Resources are scattered, the tech is complex, and it's constantly changing. I wanted to contribute a resource to make learning easier. manning.com/books/server-s… (1/5) 🧵

I've been working on making it easier to run higher-level apps (e.g., Python) in #Hyperlight by adding POSIX support to our micro-VMs. Posted about it on MSFT's OSS blog (see below). It features a demo w/ Hyperlight micro-VMs running AI generated code :) opensource.microsoft.com/blog/2026/1/28…

🎤 The RustConf 2026 CFP is OPEN! We’re looking for talks that share real experiences using Rust — what you’re building, what you’ve learned, and what’s working in practice. Submit your proposal by February 16: bit.ly/3LtKTzx #rustconf #rustconf25

Anyway, I'm really proud to be able to hold a book I've written myself, so figured I'd share. Big thanks to the team at @ManningBooks, everyone who reviewed the book, Brendan Burns for the foreword, and Luke Wagner for the afterword. (5/5) 🧵

I also took inspiration from one of my favourite technical books, Accelerated C++ by Andrew Koenig and Barbara E. Moo. Like that book, you'll apply what you learn to a running project (a smart content management system) at the end of every chapter. (4/5) 🧵

WebAssembly isn't just for the frontend. Server-Side WebAssembly by @danologue shows how to use components, WASI, and backend architecture together to build real web back ends — anchored by a practical CMS project Now in print. 50% off through Jan 12th: hubs.ly/Q03Zz18L0

📣 Deal of the Day 📣 Jan 3 Now in print! HALF OFF today! Server-Side WebAssembly: Building portable and secure multi-language apps & selected titles: hubs.la/Q03ZpzBw0 "WebAssembly on the server is the future of computing." - Solomon Hykes, founder of Docker This book lays out everything you need to take #WebAssembly beyond its traditional browser domain. By following the numerous practical examples and crystal-clear explanations, you'll soon be seeing the benefits of reduced cold start times, improved security and performance, and the freedom of polyglot programming. @danologue #wasm #rustlang #rust

Tired of trading performance for safety? Or portability for speed? WebAssembly challenges that tradeoff. Server-Side WebAssembly by @danologue shows how to use it in real systems. Now in print! 50% off with code chiarlonePB through Dec 31st: hubs.la/Q03YplVG0

Another book gone to print this week. I like the assembly angle. Early in my career I wrote a fair bit of 6502 assembly, 8086 assembly, and even quite a bit of Xerox Sigma VI assembly. Those were good days, and I enjoyed dropping into assembly from the various higher level languages I was coding in. Sometimes my doing that was justified, and other times I really shouldn't have. We grow in wisdom (hopefully!) as we progress in life. #wasm #webassembly #assembly @danologue @ManningBooks manning.com/books/server-s…

Kubernetes shouldn’t have to choose between speed & safety. See how Hyperlight and Nanvix combine container-level performance with VM-level isolation. Watch @danologue’s live demo at @rejektsio (15:10 EST): hubs.la/Q03ScNf_0 Check out Dan's book in our KubeCon bundle: hubs.la/Q03ScL7G0

Rust is fast & efficient. But how do you bring an existing codebase up to that level? Today 3:45 PT at #RustConf: @danologue (author of Server-Side WebAssembly) & Ludvig Liljenberg share how they re-engineered Microsoft’s Hyperlight in Rust. → Register: hubs.la/Q03GvrLD0 → Book 45% off (code: RustConf25): hubs.la/Q03GvxH_0

@thenewstack covered a talk I gave with Mikhail Krinkin at @rejektsio Europe 2025 on running Wasm workloads with hypervisor isolation, including a use case with Envoy filters. Worth a read: thenewstack.io/webassembly-hy… thenewstack.io/webassembly-hy…

Will be speaking at @rustconf this year about Hyperlight together w/ one of my co-workers, Ludvig Liljenberg! We'll be going over how Rust helped shape the design of the codebase, and how we ported it from C# to 100% Rust. Come say hi if you’re attending! #rustlang #hyperlight
