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.

Borgo is a statically typed language that compiles to Go
The sibling pretty much sums it up. But if you want more detail, read on:
Generally, there are three publishing options that each make sense depending on scenario:
JIT + host runtime: by definition portable, includes slim launcher executable for convenience, the platform for which can be specified with e.g. -r osx-arm64[0].
JIT + self-contained runtime: this includes IL assemblies and runtime together, either within a single file or otherwise (so it looks like AOT, just one bin/exe). These requires specifying RID, like in the previous option.
AOT: statically linked native binary, cross-OS compilation is not supported officially[1] because macOS is painful in general, and Windows<->Linux/FreeBSD is a configuration nightmare - IL AOT Compiler depends on Clang or MSVC and a native linker so it is subject to restrictions of those as a start. But it can be done and there are alternate, more focused toolchains, that offer it, like Bflat[1].
If you just want a hello world AOT application, then the shortest path to that is `dotnet new console --aot && dotnet publish -o {folder}`.

Native AOT Overview
I've been wondering how to integrate modern .NET Core into a custom build system (buck2) and was wondering similar things. There's this project I think is cool called bflat[1] that basically makes the C# compiler more like the Go compiler in the sense it's a one-shot single-use tool that can cross compile binaries natively. It's done by one of the people on the .NET Runtime team as a side project, but quite neat.
I think in practice you're supposed to compile whole .dll's or assemblies all at once, which acts as the unit of compilation; I don't think the csharp compiler generates native object-files-for-every-.cs, the kind of approach you'd expect from javac or g++. Someone please correct me if I'm wrong though! I'd like to learn more about this.

Hey people, made a game for my CS homework as a freshman using C#, what do you guys think about it?
nice. have you tried compile it using https://github.com/bflattened/bflat to have native executable? as long as you don't have PackgeReference it can be compiled using bflat instead of full dotnet

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.

Redis License Changed
https://github.com/dotnet/dotnet exists for source build that stitches together SDK, Roslyn, runtime and other dependencies. A lot of them can be built and used individually, which is what contributors usually do. For example, you can clone and build https://github.com/dotnet/runtime and use the produced artifacts to execute .NET assemblies or build .NET binaries.

Garnet – A new remote cache-store from Microsoft Research
Yeah, it kind of is. There are quite a few of experiments that are conducted to see if they show promise in the prototype form and then are taken further for proper integration if they do.
Unfortunately, object stack allocation was not one of them even though DOTNET_JitObjectStackAllocation configuration knob exists today, enabling it makes zero impact as it almost never kicks in. By the end of the experiment[0], it was concluded that before investing effort in this kind of feature becomes profitable given how a lot of C# code is written, there are many other lower hanging fruits.
To contrast this, in continuation to green threads experiment, a runtime handled tasks experiment[1] which moves async state machine handling from IL emitted by Roslyn to special-cased methods and then handling purely in runtime code has been a massive success and is now being worked on to be integrated in one of the future version of .NET (hopefully 10?)
