Gentle Introduction To Typescript Compiler API
Use it as a Front-End for other low-level languages.

TypeScript Is Surprisingly OK for Compilers
> MHO typescript could just cut loose from its javascript compatibility. Why not compile it to wasm instead of transpiling it to javascript?
Check out AssemblyScript which is exactly that:
-
Do you think typescript will ever have native support on brosers? Or we will have only the JS type annotations?
If you're curious, check out AssemblyScript, that might describe better what needs to be cut from TypeScript to make it possible to be compiled to WASM.

Ezno's checker (a Javascript type checker and compiler written in Rust) is now open source
This is kinda the idea behind AssemblyScript, but IIRC it's more of a low-level typescript-ish syntax for WebAssembly.
-
Is there a TypeScript to native compiler available?
https://www.assemblyscript.org/ maybe, but I'm not sure exactly what you need.

Emerging Rust GUI libraries in a WASM world
Exactly, WASM was designed to be very very lightweight... you can put a lot of logic into a very small amount of WASM, but you need a good compiler to do that, or write WASM by hand to really feel the benefit. If you just compile Go to WASM, with its GC, runtime and stdlib included in the binary, yeah it's going to be pretty heavy... Rust doesn't have a runtime but as you said, for some reason, produces relatively large binaries (not the case only in WASM by the way). Probably, the best ways to create small WASM binaries is to compile from C or from a WASM-native language like AssemblySCript (https://www.assemblyscript.org).

Dan Abramov responds to React critics
Well we have all the new ECMA standards that will be introduced in 5 years now. It's looking more like Java actually. its accessor and typing patterns match it the most. TypeScript has had quite the profound influence over future ECMA design. There is a not so well known project called AssemblyScript which I think has a promising future. Since future ecma standards closely resembles it and TypeScripts popularity has exploded I have a feeling it may become a real standard as well.

Do any engines or optimizers product TS-specific performance gains?
If you can guarantee that Typescript type hints will always be followed, you can turn it into more optimised code. Unfortunately, this means you've got to break Javascript semantics, so this means creating a new language, but people have done it. For example, AssemblyScript is a language that is designed as a strict subset of Typescript that compiles directly down to WebAssembly instead of Javascript, producing much more efficient code (most of the time). The tradeoff is that it has some slightly different semantics to Javascript, which means your existing codebase — and most of the libraries you use — will probably require some adaption before running correctly in AssemblyScript.

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.)
