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.

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

Best .net/c# resources for senior engineer
Sort of, some topic are not relevant anymore, consider this - https://github.com/dotnet/coreclr/tree/master/Documentation/botr
-
Is there a C# under the hood tutorial?
Fairly advanced stuff but the Book Of The Runtime (BOTR) it's a invaluable resource
-
In depth learning of C#?
After that you can check out the The Book of the Runtime, which is the CoreCLR version of the previous book.

.NET 6 is now in Ubuntu 22.04
Technically the restrictions already exist, just as a part of the development experience.
- .NET Hot Reload is only implemented on Windows. It requires support in the .NET runtime, which is technically possible to implement, but the team has not gotten around to implementing it for years. This doesn't have to do with the issue around MS removing the "dotnet watch" command, it's for the "Edit and Continue" feature in IDEs.[1][2]
- MS was considering deprecating Omnisharp, the open-source language server that implements C# support for VS Code, and replacing it with a closed-source version. Since the announcement, commits to omnisharp-vscode have dropped off significantly. The lack of Omnisharp would mean there would be no real open-source C# development environment for Linux anymore, since MonoDevelop was abandoned a few years ago. [3]

what a .NET specialist should know
The next step is to realize everything you think you know about .NET is just an abstraction. Next step is to learn about what is going on behind all that syntax sugar and facades. 1st step might be https://github.com/dotnet/coreclr/tree/master/Documentation/botr then go down the rabbit hole and have fun

Is CLR via C# still good?
Book of the Runtime

Understanding dotnet
As for the books, back in the days I really enjoyed reading “CLR via C#" by Jeffrey Richter which helped a lot to understand what is under the hood. Other from that, try The Book of the Runtime

.NET 6 is now in Ubuntu 22.04
I have two DigitalOcean sites on the same VPS just serving from kestrel behind an nginx reverse proxy and then one site on a Hetzner VPS where I was playing around with k3s.
For digitalocean I followed this post which is probably way out of date now https://www.hanselman.com/blog/publishing-an-aspnet-core-web...
For the k3s site the source is here https://github.com/EliotJones/LetsShip/blob/main/kubernetes/... though worth noting I have set up LetsEncrypt incorrectly but that's my lack of k3s understanding.

We need to have a talk about making life easier for newcomers to .NET
This - https://github.com/EliotJones/LetsShip - hopefully gets you some of the way, it uses VS on Windows for development but I can't imagine the experience in Rider or VS Code for Linux is too disimilar. Individual steps here https://github.com/EliotJones/LetsShip/tree/main/docs/posts
I need to complete the full guide at some point but the end result is an application deployed on Linux with both a web app and independently scalable crawling services with zero downtime deployments. Hosted site here: https://pricefalcon.me/
For a simpler deployment without k3s, this guide is the one I originally followed for my trends site and should still work for .NET 6. https://www.hanselman.com/blog/publishing-an-aspnet-core-web...

Synchronizing access to a pool of resources
One example here https://github.com/EliotJones/LetsShip/blob/main/src/PriceFalcon.JobRunner/Worker.cs#L111 where I have several agent applications each of which may start up to 5 jobs, a job can take a couple of minutes to execute and while running the same request twice isn't the end of the world I'd prefer to avoid it. I use FOR UPDATE when selecting to take an update lock on the row in postgres (similar functionality hopefully exists for your DB).

New Core MVC App with jQuery in 2021?
I just build out a new MVP site for the purposes of a tutorial with .NET 5 and jQuery with some slightly complex front-end requirements (an interactive iFrame that validates user selections server-side on click) and though it may need to move to an SPA if it got more complex for now jQuery is fine (though assuming IE support is not needed I could have probably just used raw JS instead). https://github.com/EliotJones/LetsShip

The Architecture of a One-Man SaaS
I've done a complete 180 on this too, I realised I was reacting from my default position of hostility to new concepts rather than an honest appraisal. I am writing it up at the moment but I've been working on a 1 person SAAS MVP tutorial [0] and though I've definitely misconfigured something having the ability to go from git push to deployed to production with 0 downtime inside of 5 minutes with no manual steps is such a nice flow, versus my previous attempts of SCP and faffing around with services.
