Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Fortran on WebAssembly
https://github.com/WebAssembly/wabt/blob/main/wasm2c/README.... is a straightforward way to take an untrusted application (compiled already to wasm) and turn it into C that you can embed into your application or compile to a linkable DLL. I believe this approach has been used to sandbox untrusted libraries in production by Mozilla: https://hacks.mozilla.org/2021/12/webassembly-and-back-again...

Understanding Every Byte in a WASM Module
This seems sort of like understanding machine code vs assembly; it's much easier to learn WAT and translate to/from WASM as necessary using the wabt tools [0].
Either way its super cool how simple WebAssembly is, you can really get your hands dirty and understand exactly every detail of how your program runs!

You mean this? https://github.com/WebAssembly/wabt/blob/main/wasm2c/README....
That seems like quite an undertaking. But at that point, It would make sense to cut out WASM entirely like https://datastation.multiprocess.io/blog/2022-05-12-sqlite-i...

WebAssembly: byte-code of the future
The .wat file can be compiled to a .wasm using wat2wasm which is part of the WebAssembly Toolkit CLI tools:

Is anyone working/creating tools for wasm in C?
it is in C++ https://github.com/WebAssembly/wabt/blob/main/src/tools/wat2wasm.cc

How to hide script file?
I don't think you are building an application that will use Native Client technologies How to extract source code from Native Client .nexe file, migrate to WebAssembly? #1864 so that would be superfluous, and frankly, useless in your case.

Hey Rustaceans! Got a question? Ask here (5/2023)!
I'm trying to get a basic Rust webassembly program, then porting it to C via wasm2c. The example works, but when I use wasm-bindgen and analyze it with wasm2wat, I get an import "env". The issue is that in C (wasm2c) it comes out as struct Z_env_instance_t; and I can't instantiate it (as in Z_env_instance_t env; to pass it's address to Z_wasm_client_bg_instantiate.

Zig self hosted compiler is now capable of building itself
To clarify I meant as int8/int16's are packed in structs to compare to struct bitfields. Can't recall about the stack rules. Here's more discussion:
http://www.catb.org/esr/structure-packing/
https://github.com/Twon/Alignment/blob/master/docs/alignment...
Also ARM for example doesn't have 8/16 bit registers so int8 or int16 will use a 32bit register:

Curiosity got to me, perhaps Zig had improved significantly. So I compared the first benchmark I found (kostya/benchmarks/bf) with Zig with Nim. For the smaller input (bench.b) Zig did run with ~22% less RAM (about 20kB less).
However, for the larger input (mandel.b) Nim+ARC used ~33% less RAM in safe mode: Nim 2.163mb -d:release; Zig 2.884mb -O ReleaseSafe; Zig 2.687mb -O ReleaseFast. The Nim requires 0.5mb less ram and the code is ~40% shorter. I don't have time to try out the Rust or Go versions though.
