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.

Exploring .NET 8 Preview 3: The 7 Features You Need to Know
This cool method lets you whip up optimized apps that get along swimmingly with Docker. Neat, huh? --platform values. Take a peek at this sample to see the pattern in action!

Need Help with C# on raspberry
You can also use the .NET Docker images to run (or build from source and then run) .NET applications.

Portability is a nightmare
Sadly, lots of dotnet apps still out there. Luckily, there's a container for that too!

(.NET/Azure) Docker mentor
Actually, it looks like I am a bit out of the loop, and there is an official .NET runtime for Linux, so you can use it like any other Linux docker images. Looks like there are examples here: https://github.com/dotnet/dotnet-docker
-
Is this Dockerfile ready for production? Is the container automatically secure?
It is good that you are thinking about security 😊. there is an issue in dotnet repo here https://github.com/dotnet/dotnet-docker/issues/1772 that have hardened examples.

Why the fuck did Microsoft name everything .NET?
You can use .NET without using ASP.NET Core (yes, the names are confusing right now, they dropped the "Core" suffix for the platform but did not drop the suffix for the web framework). Microsoft publishes a Docker image for .NET for when you just want to run some compiled CIL, but they also provide a Docker image where it includes .NET and ASP.NET Core for when you run a compiled ASP.NET Core web app. (https://hub.docker.com/_/microsoft-dotnet/)

Multi-Image Docker Images: Using COPY with Images directly from registries
Keeping the whole Maritime theme alive with Docker (and Kubernetes), I jumped into the sea of Docker Hub with millions of containers and found out that Microsoft hosts all the .NET related container images as .NET by Microsoft registry.

Swift was always going to be part of the OS
> There's definitely things they tried to improve on that... weren't really improvements. The way "assemblies" are matched in .NET is much more sophisticated- the goal there was to try to kill DLL hell. It evolved into the Global Assembly Cache, which is sort of the Windows Registry of DLLs. Not a huge fan of those bits.
The Global Assembly Cache did not make the jump to the modern .NET (Core). There was the thing called `dotnet store`, but it’s broken since .NET 6: https://github.com/dotnet/sdk/issues/24752
The assembly redirection hell has also been greatly reduced there.

.NET Blazor
I do the same.
I have a small write-up here: https://chrlschn.dev/blog/2023/10/end-to-end-type-safety-wit...
You get end-to-end type safety (even better once you connect it to EF Core since you get it all ways to your DB).
With this setup with hot-reload (currently broken in .NET 8 [0]), productivity is really, really good. Like tRPC but with one of the most powerful ORMs out there right now.

LÖVE: a framework to make 2D games in Lua
That's a twisted and wrong narrative
Unity like refers to a Editor driven approach
Unity became popular with its moonscript language (javascript like), they then ditched it to focus on C#, but what propelled unity to what it is today is the Editor driven approach, not c#, not DOTS
They are forced to transpile C# to C++ via IL2CPP as a result to target consoles/mobiles
C# is a disease when it comes to console/mobile support
It's a substantial dependency, quite heavy
And you are not free of unity like fuck ups, it's a microsoft language after all:
https://github.com/dotnet/sdk/issues/22247
And let's not forget when they changed the license of their debugger overnight to prevent people from using it in their products (jetbrains for example)
And them deprecating open source tooling to a proprietary/closed one for vscode (c# devkit)
Let's be careful when we recommend evil as an alternative to evil ;)

How to run multiple programs like python3 filename.py???

Writing Python like it's Rust
Another difference you might be surprised by is that the .NET tooling by default collects various data from your system and sends it to Microsoft [1]. If you want to avoid this (and still want to use .NET) you'll have to make sure that the environment variable DOTNET_CLI_TELEMETRY_OPTOUT is set in all contexts before touching anything.
