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.

Optimizing CPU Load in C#: Key Approaches and Strategies
If you develop projects in Unity - i really recommend to see at UniTaks.

async/await or Coroutines?
Give the UniTask library a look https://github.com/Cysharp/UniTask
-
Discussion: Is it a Good Practice to just... avoid Coroutines entirely?
What I would say, however, is that I much prefer async / await via UniTask over standard Coroutines!
- Do coroutines produce garbage?
-
Addressables - loading/unloading the same AssetReference more times - help
Lastly I recommend using UniTask to better await an asset load, use it, and release it without clunky Coroutines. Happy to give examples of how to use UniTask to update this code.
-
Why are my statements called asynchronous?
If you absolutely must muck about with threads in Unity yourself (though I struggle to think of a reason why you'd need to for the example given) then Unity's Jobs system is probably the way to go - though in most cases you can likely achieve whatever it is you're trying to achieve using something like UniTask (my preference) which gives you much nicer async / await support.

Async void VS Threads
Great comment. The Unity task library is UniTask.
-
For loop inside async task?
There are a few problems. Firstly use UniTask for async related things in Unity. Provides much better async integration with Unity.
-
How to replace IEnumerator and coroutines with async/await?
This is where UniTask comes in. If your project relies heavily on asynchronous code-- it sounds like it does -- you'll likely enjoy this package. It doesn't allocate, hooks into Unity's PlayerLoop for per-frame timing, and allows for return types. You can even await existing Coroutines.
-
Do you remember some of your most annoying problems with Unity when you just started?
UniTask is a popular async/await library that doesn't have this problem.

The search for easier safe systems programming
.NET has explicit tailcalls - they are heavily used by and were made for F#.

Arena-Based Parsers
The description indicates it is not production ready, and is archived at the same time.
If you pull all stops in each respective language, C# will always end up winning at parsing text as it offers C structs, pointers, zero-cost interop, Rust-style struct generics, cross-platform SIMD API and simply has better compiler. You can win back some performance in Go by writing hot parts in Go's ASM dialect at much greater effort for a specific platform.
For example, Go has to resort to this https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f... in order to efficiently scan memory, while in C# you write the following once and it compiles to all supported ISAs with their respective SIMD instructions for a given vector width: https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (there is a lot of code because C# covers much wider range of scenarios and does not accept sacrificing performance in odd lengths and edge cases, which Go does).
Another example is computing CRC32: you have to write ASM for Go https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f..., in C# you simply write standard vectorized routine once https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (its codegen is competitive with hand-intrinsified C++ code).
There is a lot more of this. Performance and low-level primitives to achieve it have been an area of focus of .NET for a long time, so it is disheartening to see one tenth of effort in Go to receive so much spotlight.

Airline keeps mistaking 101-year-old woman for baby
It's an interesting "time is a circle" problem given that a century only has 100 years and then we loop around again. 2-digit years is convenient for people in many situations but they are very lossy, and horrible for machines.
It reminds me of this breaking change to .Net from last year.[1][2] Maybe AA just needs to update .Net which would pad them out until the 2050's when someone born in the 1950s would be having...exactly the same problem in the article. (It is configurable now so you could just keep pushing it each decade, until it wraps again).
Or they could use 4-digit years.

The Performance Impact of C++'s `final` Keyword
Yes, that is true. I'm not sure about JVM implementation details but the reason the comment says "virtual and interface" calls is to outline the difference. Virtual calls in .NET are sufficiently close[0] to virtual calls in C++. Interface calls, however, are coded differently[1].
Also you are correct - virtual calls are not terribly expensive, but they encroach on ever limited* CPU resources like indirect jump and load predictors and, as noted in parent comments, block inlining, which is highly undesirable for small and frequently called methods, particularly when they are in a loop.
* through great effort of our industry to take back whatever performance wins each generation brings with even more abstractions that fail to improve our productivity

Java 23: The New Features Are Officially Announced
If you care about portable SIMD and performance, you may want to save yourself trouble and skip to C# instead, it also has an extensive guide to using it: https://github.com/dotnet/runtime/blob/69110bfdcf5590db1d32c...
CoreLib and many new libraries are using it heavily to match performance of manually intensified C++ code.

Why choose async/await over threads?
We might not be that far away already. There is this issue[1] on Github, where Microsoft and the community discuss some significant changes.
There is still a lot of questions unanswered, but initial tests look promising.
