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.

Asynchronous Programming in C#
Important: following #prefer-asyncawait-over-directly-returning-task from https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/b... is not correct.
The concerns raised are niche and edge case and task must always be forwarded as is provided there is no post-processing or resource cleanup with idisposable.

Give me your async/await gotchas
This one is a pretty decent guide - https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/blob/master/AsyncGuidance.md

What's the Benefit/Allure of Async/Await vs. CSP/Green Threads (and Other Concurrency Models)?
The C# (mostly applicat community has e.g. https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/blob/master/AsyncGuidance.md written by one of the Asp.Net architects. I found this in this lovely thread https://news.ycombinator.com/item?id=36785691 which expresses my views/confusion more clearly than I can express.

The State of Async Rust
No it doesn't, hence why there are best practices guidelines written by the .NET architects, and there was a research project to add Go/Java co-routines as well.

The Downsides of C++ Coroutines
They don't work just fine in C#, there is a reason why one of ASP.NET architects has written a guide of best practices.

No-GIL mode coming for Python
Many that praise async/await in C#, kind of forget it took about 10 years to spread across all the layer of the language and runtime, since it was done via IL rewriting, it caused several issues with F# async tasks, due to the age of the ecosystem plenty of code isn't async/await friendly and needs to be wrapped into Task.Run() or similar.
There is a best practices guideline from one of the ASP.NET architects, https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/b...
During last year they researched adding Go/Java's approach to .NET, but now it is too late. See the ASP.NET Q&A session at BUILD 2023.

Task vs threads - use cases
The best guidance I have found was from here: AsyncGuidance.md

How Much Memory Do You Need to Run 1M Concurrent Tasks?
To expand upon this thought, here is the AsyncGuidance doc[1] on why not to use .Result to get the return value of a completed Task in C#.
To make this simple they introduced async Main[2] a few years ago.

Ruby 3.3's YJIT: Faster While Using Less Memory
Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago.
If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly ruby-like in syntax, style, and developer ergonomics.[^2] Although it's an entirely different language. Also a tiny community.

What languages are useful for contribution to the GNOME project.
Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well.

Jets: The Ruby Serverless Framework
Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything.
My modern programming toolkit is basically golang + ruby + bash and I am never left wanting.
I do find Crystal (https://crystal-lang.org/) really interesting and am hoping it has its own "ruby on rails" moment that helps the language reach a tipping point in popularity. All the beauty of ruby with all of the speed of Go (and then some, it often compares favorably to languages like rust in benchmarks).
