Spin 2.0 – open-source tool for building and running WASM apps
I'm impressed you're already leveraging the component model. I thought it wasn't quite ready for primetime yet, but it seems you're proving that wrong... I'll have to dig in more here, as I'm working embedding WebAssembly in a high performance storage engine.
Thanks for the notes! I hear you on QuickJS - I've seen approaches of folks trying to build more node compatibility on top of quickjs (ala https://github.com/second-state/wasmedge-quickjs), but have recently heard about spidermonkey in wasmtime. Do you have intuition for nodejs vs browser in terms of what people want in terms of compatibility?

How to compile serveTls for import into QuickJS?
I can conceptualize a way to convert JavaScript source code to WASM then convert WASM to C source code. I have considered just using WASM, however, that introduces yet another runtime to manage https://github.com/second-state/wasmedge-quickjs.

How to import prompt()?
Technically you can create a C shared object and import that shared object into QuickJS, see https://github.com/rsenn/qjs-modules, also https://github.com/second-state/wasmedge-quickjs.

Easier examples for the WasmEdge Rust SDK to get started with this Wasm runtime quickly.

Backdoor in upstream xz/liblzma leading to SSH server compromise
Just a documentation change, fortunately:
https://github.com/bytecodealliance/wasmtime/commits?author=...
They've submitted little documentation tweaks to other projects, too, for example:
https://learn.microsoft.com/en-us/cpp/overview/whats-new-cpp...
I don't know whether this is a formerly-legitimate open source contributor who went rogue, or a deep-cover persona spreading innocuous-looking documentation changes around to other projects as a smokescreen.

Unlocking the Power of WebAssembly
WebAssembly is extremely portable. WebAssembly runs on: all major web browsers, V8 runtimes like Node.js, and independent Wasm runtimes like Wasmtime, Lucet, and Wasmer.

Prettier $20k Bounty was Claimed
The roadmap I linked above. The WASI folks have done a poor job at communicating, no doubt, but I'm surprised someone like yourself literally building a competitor spec isn't following what they are doing closely.
Just for you I did some googling: see here[0] for the current status of WASI threads overall, or here[1] and here[2] for what they are up to with WASI in general. In this PR[3] you can see they enabled threads (atomic instructions and shared memory, not thread creation) by default in wasmtime. And in this[4] repository you can see they are actively developing the thread creation API and have it as their #1 priority.
If folks want to use WASIX as a quick and dirty hack to compile existing programs, then by all means, have at it! I can see that being a technical win. Just know that your WASIX program isn't going to run natively in wasmtime (arguably the best WASM runtime today), nor will it run in browsers, because they're not going to expose WASIX - they're going to go with the standards instead. so far you're the only person I've met that thinks exposing POSIX fork() to WASM is a good idea, seemingly because it just lets you build existing apps 'without modification'.
Comical you accuse me of being polarizing, while pushing for your world with two competing WASI standards, two competing thread creation APIs, and a split WASM ecosystem overall.

Spin 2.0 – open-source tool for building and running WASM apps
Thanks for the question!
Spin could definitely run in more places than what we have pre-built binaries for. Specifically, we could run on all platforms Wasmtime supports today (https://github.com/bytecodealliance/wasmtime/releases/tag/v1...), including RISC and S390X, for example.
And while we have been experimenting a bit with running Spin on RISC, we haven't really had the bandwidth or requirement to build a production build for those yet.
Are you interested in a specific operating system or CPU architecture? Would love to understand your scenario.

Dave Cutler: The Secret History of Microsoft Windows [video]
> I used to think we'd eventually get to capability based security, but now I see we'll always be stuck with application permission flags, the almost worthless bastard cousin, instead.
My hope is that WASI will introduce capability based security to the mainstream on non-mobile computers [0] - it might just take some time for them to get it right. (And hopefully no half-baked status-quo-reinforcing regressive single—runtime-backed alternatives win in the meantime.)
