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.

Stop Hiding the Sharp Knives: The WebAssembly Linux Interface
I would really love being able to take any POSIX command line tool, compile that to WASI, and run it on (at least) Linux, Windows and macOS like a regular executable without having to install a separate WASI runtime.
I'm a 'WASI convert' since I was able to take an ancient 8-bit assembler written in the mid-90's (http://xi6.com/projects/asmx/), compile that as-is with the WASI SDK (https://github.com/WebAssembly/wasi-sdk), and then integrate it into a VSCode extension (https://marketplace.visualstudio.com/items?itemName=floooh.v...).
A similar problem is I have is a shader cross-compiler (https://github.com/floooh/sokol-tools) which needs to run Linux, macOS and Windows and takes too long to build locally, thus I currently need to distribute that as pre-built binaries. Compiling this to WASI works, but the filesystem access restrictions built into current wasm runtimes are a hassle to manage, and it would require a WASI runtime to be separately installed).

WASI: WebAssembly System Interface
There is the WASI SDK if you want to target WASI from C/C++:
https://github.com/WebAssembly/wasi-sdk
It may not have all the amenities of Emscripten, but it's way less bulky.

How to Debug WASI Pipelines with ITK-Wasm
The most direct way to debug WebAssembly is through the WebAssembly System Interface (WASI). In itk-wasm, we can build to WASI with the WASI SDK by specifying the itkwasm/wasi toolchain image. A backtrace can quickly be obtained with the itk-wasm CLI. Or, a fully fledged debugger session can be started with LLDB.

Hello Wasm World!
We use the add_executable command to build executables with itk-wasm. The Emscripten and WASI toolchains along with itk-wasm build and execution configurations are contained in itk-wasm dockcross Docker images invoked by the itk-wasm command line interface (CLI). Note that the same code can also be built and tested with native operating system toolchains. This is useful for development and debugging.

Wasmer takes WebAssembly libraries mainstream with WAI
A more lightweight tool than emscripten is the WASI SDK (https://github.com/WebAssembly/wasi-sdk/releases). However, it doesn't generate JS or HTML.

Turbocharge your application development using WebAssembly with SingleStoreDB
First, we’ll download the wasi-sdk. We’ll use wasi-sdk-16.0-linux.tar.gz, the latest version available when writing this article. We’ll move the file to the /opt directory and unpack it as follows:

whats all the fuzz about wasi-libc?
I'm intrigued. Pretty good write-up about it here. One would need an ebuild for wasi-libc and an ebuild for wasi-sdk.

Store SQLite in Cloudflare Durable Objects
The previously mentioned PR for wasm32-unknown-unknown compatibility solved this by including libc .c files from OpenBSD. My go to solution is different though. I prefer to build using the wasi-sdk (a WASI-enabled WebAssembly C/C++ toolchain).

WebAssembly and Back Again: Fine-Grained Sandboxing in Firefox 95
There's also the https://github.com/WebAssembly/wasi-sdk repo which is kind of a meta-build-system for all this.
But in FreeBSD we build all the pieces directly, here's our build recipes (with some hacks due to llvm's cmake code being stupid sometimes):
compiler-rt (from llvm): https://github.com/freebsd/freebsd-ports/blob/main/devel/was...
libc (from what you linked): https://github.com/freebsd/freebsd-ports/blob/main/devel/was...
libc++ (from llvm): https://github.com/freebsd/freebsd-ports/blob/main/devel/was...

How to Debug WASI Pipelines with ITK-Wasm
Effective debugging results in effective programming; itk-wasm makes effective debugging of WebAssembly possible. In this tutorial, adapted from the itk-wasm documentation, we walk through how to debug a C++ data processing pipeline with the mature, native binary debugging tools that are comfortable for developers. This is a fully featured way to ensure the base correctness of a processing pipeline. Next, we will walk through an interactive debugging experience for WASI WebAssembly. With itk-wasm, we can debug the same source code in either context with an interactive debugger. We also have a convenvient way to pass data from our local filesystem into a WebAssembly (Wasm) processing pipeline.

Create Elegant C++ Spatial Processing Pipelines in WebAssembly
In this post, adapted from itk-wasm's documentation, we provide a C++ Wasm processing pipeline tutorial that demonstrates how we can write elegant processing pipelines in C++ via itk-wasm's CLI11 command line parser, which provides a rich feature set with a simple and intuitive interface. At the end of this tutorial, you will have built and executed C++ code to Wasm for standalone execution on the command line and in the browser.
