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.

Is .NET just miles ahead or am I delusional?
Do these all compile to the exact same thing?

Yes, so you are right.

Generating C# code programmatically
Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

The One Billion Row Challenge – .NET Edition
One results in MOVSX, the other in MOVZX [1]. The difference thus is sign/zero extension when moving to the larger register. However, they seem to perform pretty much identical if I'm reading Agner Fog's instruction tables correctly.

C# Testing Playgrounds for old versions?
The closest online tool I can think of would be SharpLab, but you can only choose between Roslyn's git branches instead of C# versions.

TypeScript 5.2's New Keyword: 'using'
Your code is destructuring two properties and discarding one of them. It doesn't work with a single property: https://sharplab.io/#v2:C4LgTgrgdgNAJiA1AHwAICYAMBYAUBgRj2Nw...
I think that records don't generate a deconstruct method when they only have one property, but even if you manually define one you'll get an error on `var (varName) = ...`

Tips for entry-level .net developer?
- LinqPad is great and I love, but, IMO, it is not the best tool to start with. It does not provide intellisense or debugger in the free version. Assuming you do not want to pay for this licence just to play a little with the language, I'd suggest https://sharplab.io/. It is not as powerfull as LinqPad, but at least it gives you suggestions.

Got my first c# software engineering job, any advice?
But to go deeper to .NET/CLR architecture is important too. Try to understand how it works inside. Use the source, Luke! https://source.dot.net/ https://referencesource.microsoft.com/ This source code vaults is not completed then try JetBrains dotPeek tool to look at any assembly source code.

Why your F# evangelism isn't working
List is an IList/IReadOnlyList; these interfaces do nothing that couldn't be done right inside the file itself.
https://referencesource.microsoft.com/#mscorlib/system/colle...
https://referencesource.microsoft.com/#mscorlib/system/colle...
Instead we have to go diving through the IList, which implements ICollection, which implements IEnumerable, which implements IEnumerable (again). Just because each interface is composed of another interface, doesn't mean you aren't using inheritance. You are effectively creating a custom inheritance tree through willy-nilly composition.
It is gratuitous to make this chain so deep, when the underlying code is just a handful of lines.

Ask HN: What book you recommend for advanced programming in C#?
Assuming if you are new to C# - start coding! And start reading https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csha...
If you are not new to C#, start building an application end-to-end/a classic n-tier application, right from using a database, Entity Framework, WebAPI, DTO, AutoMapper, and a front-end (your choice - Angular/React/Vue with TypeScript or better yet - Blazor).
You will not only understand & use dependency injection, reflection, LINQ, multi-threaded programming, generic programming, source-code generation, unit-testing - and much much more in a practical/real-world usage.
Peruse https://referencesource.microsoft.com/ once in a while.
Follow various team members of .NET Framework, C# team and the like on various social-media. https://mobile.twitter.com/i/lists/120961876
I am sure there will be who agree / disagree with the above approach and will provide more viewpoints for you to consider.
Enjoy - and strap yourself for an amazing journey or roller-coaster ride, however you want to call it!
