if anyone is curious about the technical details, I recently gave a talk about BrowserPod's architecture at the Wasm I/O conference. The recordings of the talks are being published on their YT channel ( https://www.youtu

I work on a project that does exactly that (and more): https://browserpod.io/ . Currently it supports Node, but we plan to add Python, Ruby, git, and more. You can see it in action in this demo: https://vitedemo.b

So using agents forces (or at least nudges) you to use go and tailwind, because they are simple enough (and abundant in the training data) for the AI to use correctly. Does this mean that eventually in a world where we all use this stuff, n

On the Web, you can do that today. This is what https://webvm.io does for example. It jit-compiles Wasm modules at runtime from the original X86.

For reference, when loading https://browsercraft.cheerpj.com for the first time (up to loading a world), my browser downloaded ~32MB. The second time almost nothing.

Looking forward to progress on the memory control proposal(s). Another reason to want more than 4GB of memory is to have more address space, assuming that you have the ability to map it. With that capability Wasm64 could be useful also for

It is a bit unfair to Wasmer, because it incur in the (presumed) overhead of `wasmer run ...`, but I could not figure out if the actual clang binary is directly available after it is downloaded the first time.

Could you elaborate on how you solved the issue? A link to the relevant code would be nice.

Actually, it was in wasi-libc: https://github.com/WebAssembly/wasi-libc/blob/main/libc-bott...

I don't necessarily disagree, but implementing these things in your custom runtime is easy. I am more interested in how they achieved them in the more constrained browser environment.

I am curious about the browser compatibility layer. Does it support networking? (And if so, is it using a proxy to connect to the internet or is it using a virtualized network layer that stays in the browser?) How is fork implemented? (Asyn

I agree. I implemented a subset of WASI, and the best resource was an autogenerated C header with function signatures and very terse comments, buried in the WASI SDK repo.

Yeah I mean, I wouldn't trust the accuracy of its answer. But I find it funny that it agrees that OpenAI should comply.

Indeed, as I said it can be a downside. What we usually suggest is to compile most of the application to Wasm (which is also the default), and move the parts that most interact with the outside world to JS. This can actually result in a spe

Disclaimer: I work on Cheerp. We do include the C (Musl) and C++ (Clang's libcxx) standard libraries. And we do have some custom LLVM passes to improve code size and performance (See for example [1] and [2]). But the main selling point

By "Wasm JIT API in JavaScript" I mean a native way for the browser to support the JIT use-case. Generating entire modules works, but it has a number of issues. For example, you need to carefully decide how big your modules are go

This is a nice overview on how to achieve just-in-time compilation in Wasm, and the demo is pretty cool. Good work! We use similar techniques to power Webvm[1], an X86 Virtual Machine that runs linux programs in the browser. A proper Wasm J
