Hi, this is Patrick Dubroy and Mariano Guerra. You're getting this email because you purchased (or signed up for updates about) WebAssembly from the Ground Up. If you're no longer interested in these emails, no hard feelings — you can find an unsubscribe link at the bottom.

Dear bytecode lovers,

We recently had the pleasure of talking to Tom Steiner on the WasmAssembly podcast ("your monthly podcast to geek out about all things WebAssembly"):

Host Thomas Steiner sits down with Patrick Dubroy and Mariano Guerra, authors of the ebook "WebAssembly from the Ground Up." Discover how they're teaching Wasm by building a compiler in JavaScript, why writing WebAssembly by hand is crucial, and their thoughts on the future of compiler education. Tune in to learn about Ohm, the surprising omission of WAT, and what a potential part 2 of their book might cover!

You can listen here, or check out the video on YouTube.

Wasm tidbits

• A paper from the recent SPLASH conference that caught our eye: A Snapshot of the Performance of Wasm Backends for Managed Languages.
• Speaking of managed languages, Ben Titzer has opened an interesting new Wasm proposal for a fine-grained JIT interface: "The main component of this idea is a new core Wasm bytecode, func.new, which creates a new function at runtime from bytecode stored in Wasm memory"
• Compose Multiplatform for web, powered by Wasm, is now in Beta: "You can share most of your UI code and rely on the same Compose skills you already have from working on Android when building for the web – no need to learn a new UI toolkit."
• Did you know about WebVM? We didn't. It's a virtual Linux environment running in the browser via WebAssembly, powered by CheerpX. "CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator."
• This week the W3C WebAssembly Community Group is holding an in-person meeting in Munich. We'll be there…Patrick on Tuesday, and both of us on Thursday for the Research Day. If you see us, say hi!

Until next time,

Patrick & Mariano
