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.

Why choose async/await over threads?
https://github.com/Xudong-Huang/may
The project has some serious restrictions and unsound footguns (e.g. around TLS), but otherwise it's usable enough. There are also a number of C/C++ libraries, but I can not comment on those.

Asynchronous Clean-Up (in Rust)
> e.g. Linux mutexes
You don't want to use blocking mutexes anyway with async.
> or Rust's Rc
This is only half true. The danger is that two `Rc` that point to the same data are in different threads. But it should be safe to move all of them at once from one thread to another, which is exactly the case if all the `Rc`s involved live inside a `Future`. The problem is that this is a non-local property that's hard to encode in the type system.
> By the way, if you wish to test uncolored async in Rust, you can find an implementation here: https://github.com/Xudong-Huang/may .
FYI that's known to be unsound due to thread locals. And more generally it doesn't seem to give much attention to safety (see for example how it allowed unsound scoped tasks, or the fact it allows doing unsafe operations in some of its macros due to wrong scoping of `unsafe` blocks).

What's the Benefit/Allure of Async/Await vs. CSP/Green Threads (and Other Concurrency Models)?
It seems that rust removed native green threads as against it's philosophy: https://stackoverflow.com/questions/29428318/why-did-rust-remove-the-green-threading-model-whats-the-disadvantage#29430403 but there are good CSP libraries e.g. https://github.com/Xudong-Huang/may and yet people really like e.g. Tokio for Async/Await (although it also has greenthreads!) What am I missing?

Async Rust Is A Bad Language
Can you admit that you failed in making it a pleasant experience to write async, especially for library authors? I don’t think it’s too late to admit failure and implement something like May https://github.com/Xudong-Huang/may

How Much Memory Do You Need to Run 1 Million Concurrent Tasks?
Your benchmark is comparing apples to oranges, you're benchmarking different things. If you wanted to compare a Rust solution to something like what Go does, you would need to use something like this library.

Can this new algorithm of Kotlin async be applied to Rust?
Yep. This is the best coroutine library right now https://github.com/Xudong-Huang/may
-
async fn calls can lead to surprising performance problems if they are nested too deeply
I am still intrigued by the stackful coroutine library, May https://github.com/Xudong-Huang/may. I would like to see how far this library can push the boundaries of being a higher level alternative to async
-
Goroutine equivalent
There is also "may" which attempts to be a Rust version of goroutines. I have not used it though, so can't comment on anything further about it.
-
Virtual Threads in Rust?
This library https://github.com/Xudong-Huang/may implement Stackful Coroutines in Rust which I believe is pretty close to what you're asking about. I believe it's a reasonably complete implementation, but it doesn't have much traction because most of the Rust ecosystem is using either async/await or native threads.

Working with Strings in Rust
I've never worked with C# so I need to look into that.
The one saving grace with Rust is if everyone decides to say "screw async" and just builds synchronous APIs, then we use something like [May](https://github.com/Xudong-Huang/may) for green threading.

Shoes makes building little graphical programs for Mac, Windows, Linux simple
As someone who has looked at Shoes several times but never dove in, it's confusing how Shoes 4 has been the "preview version" of Shoes for, like, a decade or more. It made me actively avoid getting invested in Shoes 3 (the release promoted on the linked website) because Shoes 4 requires JRuby and I am happy with CRuby (the Ruby interpreter most people think of when they hear "Ruby").
https://github.com/shoes/shoes4/
http://www.rubydoc.info/github/shoes/shoes4
No disrespect to the developers but to me it feels like taking over a GUI toolkit created "to teach programming to everyone" (to quote the Shoes 4 readme) and making it depend upon a super-complicated enterprise-focused Ruby was sort of Missing The Point™ in a huge way.
Heck I couldn't even switch to JRuby if I wanted to because I <3 Ractors and JRuby still lacks CRuby 3.0 feature parity: https://github.com/jruby/jruby/issues/7459

Communication Counts – Leading a New Generation of Developers with Chris Mar
Chris: Yeah, that's exactly right. So I was working at Sun at the time. I remember the JRuby guys. I saw them speak at one of the Java conferences, and they came to work for Sun. Just listening to them talk about JRuby...and then a lot of it was obviously about Ruby on Rails at the time. And I was like, wow, this was just mind-blowing the way they talked about it.

Befunge GUI by Glimmer (2 for 1: LibUI & SWT)
In fact, I built its GUI twice with two different approaches, one using the up and coming Glimmer DSL for LibUI on CRuby relying on a multi-canvas-grid (LibUI area) approach, and one using the very mature Glimmer DSL for SWT on JRuby by relying on a button-grid approach.
What are some alternatives?
