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.

How exactly does updating work
This is actually a difficult problem. The general idea is that you can figure out where your application is installed, download a new version of it, and replace it. However in practice it is difficult to do in a way that works with various operating systems policies. For an example, you can see how Chrome manages this on windows https://github.com/google/omaha

Google Chrome emergency update fixes zero-day used in attacks
You don’t opt-in to updates to Chrome and you will have one hell of a time opting out. If you’re on Windows, take a look at your task scheduler and notice that the Google Update task runs every hour in which it sends the current version of Chrome (stored in registry) to a Google URL and if that doesn’t match the latest then Google Chrome updates. You just need to restart your browser. Google update is a branded open source project called Omaha which is a very minimal and clever approach to application updates. Here’s the GitHub if you’re interested in learning more.

Breeze Browsers.
They use a fork of Omaha Updater for updates on Windows (I use Windows btw, it sucks)

Updating Google Chrome
Hi there. Chrome uses GoogleUpdate.exe to... er... update itself. GoogleUpdate is based on a project called Omaha. There is pretty good detail on how it works here. It might be as simple as force-running GoogleUpdate.exe with PowerShell to kickoff the update process.

WebAssembly Playground
Some things that might greatly increase wasm usage and overall tooling:
1) Tools that run docker containers and serverless function services (like AWS lambda) to support providing a .wasm files instead
2) Garbage collection in the runtime to make GC languages easier to port to wasm
3) Dynamically typed languages (NodeJS, Python, Ruby) being able to compile to webassembly directly instead of porting the runtime to webassembly and then running the code through the runtime. This is a big ask though, basically needs to redesign the runtime completely
4) wasm-DOM bindings will enable other languages to do HTML rendering which will require new web frameworks for every language that wants to take over the space from JS. This will lead to (even more) fragmentation of the web ecosystem
5) A new wasm-first SDK (unrelated to the DOM) for building cross platform applications. I can see this taking off only if it is built-into the browsers and backed by some standards committee, so not very likely I think
6) Something like the Interface Types proposal ( https://github.com/WebAssembly/interface-types/blob/main/pro... ) becomes a thing allowing wasm programs to be consisted of modules written in several different languages and being able to call said modules with low or 0 runtime performance hit (and of course, no compilation to multiple CPU archs). So much of programming ecosystems are locked to specific languages (like data science with python) when there is little technical reason for it be like that.

Bring garbage collected programming languages efficiently to WebAssembly
AFAIK GC is irrelevant for "direct DOM access", you would rather want to hop into the following rabbit hole:
- reference types: https://github.com/WebAssembly/reference-types/blob/master/p...
- interface types (inactive): https://github.com/WebAssembly/interface-types/blob/main/pro...
- component model: https://github.com/WebAssembly/component-model
If this looks like a mess, that's because it is. Compared to that, the current solution to go through a Javascript shim doesn't look too bad IMHO.

Rust & Wasm (Safe and fast web development)
I'm not really optimistic that particular aspect will get much improvement. Many people expected interface types to come save the day, but after a looong stagnation that proposal has been archived (for now) in favour of component types, which has much less potential for performance gains.
-
Plugins in Rust: Wrapping Up
Really good questions. Unfortunately, most of the issues I found back then were fundamental ones. I've seen that Wasm has deprecated "Interface Types" and is now working on the "Component Model". But even then, as far as I understand that would only avoid the serialization and deserialization steps, and you would still need to copy complex types. It will be more performant, but I don't think it would be enough for Tremor either.

When moving from JS to WASM is not worth it - Zaplib post mortem
wasm doesn't know anything about the outside world on purpose. This allows it to be used in other domains. For direct access to the DOM et al, interface types are being developed. It's a non-trivial problem to interoperate with a dynamically typed GC'd language from any statically typed no-GC language that can compile to wasm.

WebAssembly 2.0 Working Draft
You may want to look into WASM interface types, which is defining what amounts to am IDL for WASM and different languages have common calling conventions: https://hacks.mozilla.org/2019/08/webassembly-interface-type...
I don’t know if there’s a better intro article. I believe this is the current iteration of the proposal: https://github.com/WebAssembly/interface-types/blob/main/pro...

Replace JS with Rust on front-end, possible? Advisable?
Yes, and if I'm not mistaken, this is the RFC

Google Chrome emergency update fixes zero-day used in attacks
I see no reason why not. See the interface types proposal for a proposed solution.

Front-end Rust framework performance prognosis
Wanted to get thoughts from the Rust experts on this - the author of the Yew framework seems to think that Web Assembly Interface Types (https://github.com/WebAssembly/interface-types/blob/master/proposals/interface-types/Explainer.md) will allow Yew to eventually become faster than Vue, React, Angular, etc. Is there general consensus on this in the Rust community? The prospect of mixing Rust (for the performance critical pieces) with TS on the front end doesn't seem super appealing to me.
