24 alternatives to WebAssembly Instrumentation in the Wizard Research Engine
Hello all, I've been working on research tools for Wasm for some time now, and just today we put up the pre-print for our newest paper "Flexible Non-intrusive Dynamic Instrumentation for WebAssembly" (https://arxiv.org/abs/2403.07973), which will appear in ASPLOS 2024. Two previous papers, one about Wizard's interpreter (https://dl.acm.org/doi/10.1145/3563311) and one about the JIT (https://arxiv.org/abs/2305.13241) have been discussed on HN before. This new paper explains what Wizard is really about: dynamic instrumentation of…

This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

Hey HN! I've been working on a book about WebAssembly over the last few months, and it's finally available at http://levelupwasm.com! Why a book on WebAssembly you ask? Well... WebAssembly is awesome (obviously ) but it's certainly not the easiest thing to learn. So I wrote this book as a practical intro to using WebAssembly in your web apps. I would appreciate any feedback!

Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell)…

I've open sourced a JavaScript to WASM compiler. It's an experimental tool, but given the semantics I already implemented, I'm fairly certain I am able to eventually cover 100% of JavaScript spec. Any ideas, questions or critique welcomed! If you are interested in WASM, especially with new proposals like WASM GC or exception handling, it might be a good source of seeing these features in action - the project has a few thousand lines of hand written WAT so far.

As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future! It misses a lot of features (that will be gradually implemented). Any feedback is welcomed!! Demo: https://luna-demo.vercel.app

Show HN: TinyWasm - A tiny WebAssembly Runtime written in Rust Hi HN! I'm excited to share TinyWasm (https://github.com/explodingcamera/tinywasm), a WebAssembly Interpreter I developed for my final university project. The main goal of this project was to deepen my understanding of WebAssembly and interpreter design. TinyWasm successfully passes all the official WebAssembly 1.0 tests and also includes features from future proposals such as like bulk memory operations. Initially more of a research project, TinyWasm focuses on simplicity and portability. It has minimal…
