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.

Rust, WASM, and LOK
First of all, a quick rundown of what WASM is. It stands for Web Assembly. In essence, similar to how Java compiles down to a bytecode that is interpreted by a Java Virtual Machine, Web Assembly is a different bytecode interpreted by the browser. Many different languages can compile into WASM, and Javascript can interface with it like a module. In my case, I wrote a lot of the source code in Rust and compiled it down to a WASM module, then called into it from Javascript.

Surprisingly Powerful – Serverless WASM with Rust Article 1
WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications. - https://webassembly.org

Reaching and surpassing the limits of JavaScript BigData with WebAssembly
With WebAssembly we can compile our C++ codebase into a wasm module for the browser. So when you look at a SciChart.js chart you're actually seeing our C++ graphics engine wrapped for JavaScript.

WASM Instructions
I should add, however, that the unmentioned elephant in the room is V8 JIT (TurboFan), which simply doesn't handle irreducible control flow. While there are some valid theoretical arguments around the current arrangement in Wasm, looking at the history of the associated discussions makes it pretty obvious that having V8 support Wasm and generate fast code similar to what it can do for asm.js was an overriding concern in many cases. And Google straight up said that if Wasm has ICF, they will not bother supporting such cases, so it will be done by a much slower fallback:
https://github.com/WebAssembly/design/issues/796#issuecommen...
AFAIK no other Wasm implementation has the same constraint - the rest generally tend to desugar everything to jumps and then proceed from there. So this is, at least to some extent, yet another case of a large company effectively forcing an open standard to be more convenient for them specifically.

Supercharge Web AI Model Testing: WebGPU, WebGL, and Headless Chrome
https://github.com/WebAssembly/design/issues/1397
> Currently allocating more than ~300MB of memory is not reliable on Chrome on Android without resorting to Chrome-specific workarounds, nor in Safari on iOS.
That's about allocating CPU memory but the GPU memory situation is similar.

Build your own WebAssembly Compiler
As far as I can tell (5 minutes of internet research) this was to allow easier compilation to JavaScript as a fallback in the days when WASM wasn't widely supported.
"Please add goto" issue has been open since 2016:
https://github.com/WebAssembly/design/issues/796
Most interesting comment:
> The upcoming Go 1.11 release will have experimental support for WebAssembly. This will include full support for all of Go's features, including goroutines, channels, etc. However, the performance of the generated WebAssembly is currently not that good.
> This is mainly because of the missing goto instruction. Without the goto instruction we had to resort to using a toplevel loop and jump table in every function. Using the relooper algorithm is not an option for us, because when switching between goroutines we need to be able to resume execution at different points of a function. The relooper can not help with this, only a goto instruction can.
> It is awesome that WebAssembly got to the point where it can support a language like Go. But to be truly the assembly of the web, WebAssembly should be equally powerful as other assembly languages. Go has an advanced compiler which is able to emit very efficient assembly for a number of other platforms. This is why I would like to argue that it is mainly a limitation of WebAssembly and not of the Go compiler that it is not possible to also use this compiler to emit efficient assembly for the web.

Flawless – Durable execution engine for Rust
When I implemented a WASM compiler, the only source of float-based non-determinism I found was in the exact byte representation of NaN. Floating point math is deterministic. See https://webassembly.org/docs/faq/#why-is-there-no-fast-math-... and https://github.com/WebAssembly/design/blob/main/Nondetermini....

Requiem for a Stringref
> To work with GC, you need some way to track if the GC'd object is accessible in WASM itself.
I've never heard of a GC with that kind of API. Usually any native code that holds a GC reference would either mark that reference as a root explicitly (eg. https://github.com/WebAssembly/design/issues/1459) or ensure that it can be traced from a parent object. Either way, this should prevent collection of the object. I agree that explicitly checking whether a GC'd object has been freed would not make any sense.
> The reason why you probably need a custom string type is so you can actually embed string literals without relying on interop with the environment.
WASM already has ways of embedding flat string data. This can be materialized into GC/heap objects at module startup. This must happen in some form anyway, as all GC-able objects must be registered with the GC upon creation, for them to be discoverable as candidates for collection.
Overall I still don't understand the issue. There is so much prior art for these patterns in native extensions for Python, PHP, Ruby, etc.

The Tug-of-War over Server-Side WebAssembly
Giving you a buffer that grows is the allocation approach I am talking about. This is not how your OS works. Your OS itself works with an allocator that does a pretty good job making sure that your memory ends up not fragmented. Because WASM is in between, the OS is not in control of the memory, and instead the browser is. The browser implementation of "bring your own allocator" is cute but realistically just a waste of time for everybody who wants to deploy a wasm app because whatever allocator you bring is crippled by the overarching allocator of the browser messing everything up.
It seems like the vendors are recognizing this though, with firefox now having a discard function aparently!

Lee's opinions on Umbraco + naming things
Why is this a problem? At face value, it isn't a problem. Taking a step back at a more global level, what does "uComponents" mean to the rest of the world? Many of the .NET developers who heavily use NuGet may have not even heard of Umbraco CMS, let alone a 3rd party plugin for it. What if people from the Uno Platform community are browsing NuGet for some kind of components extension library? You can see, this could get confusing outside the scope of the Umbraco community/ecosystem. On top of this, uComponents was developed against Umbraco v4, with its last release in 2016, now it's there to be lingering on the NuGet repository until the end of time, set in stone.

Dart 3.1 and a retrospective on functional style programming in Dart
Not a fan of XAML after trying to get into it, but there is Uno Platform. It wraps native widgets on mobile, just like React Native (which is good for accessibility), and uses C#. https://platform.uno/
My guess is that it's mainly focused on mobile. On Windows, it has no overhead (behaving like a normal WinUI 3 app), on macOS I think it uses Catalyst by default (which was developed by Apple to make more iOS apps available for Mac desktops) and on Linux it draws its own widgets that the devs try imitating the GTK style with.
On Android and iOS, it just uses the native widgets which I think is a better experience so you can see my reasons for guessing it's mobile-first. That may or may not be what you want.

When the whole premise is flawed, JSX or not, does it really matter if there is a better or worse way of misusing a technology not meant for UIs?
