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.

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.

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!

C Is the Greenest Programming Language
Looking at the benchmark where C++ is worst compared to other languages, it's depending on the library used. I would guess if they used Google's re2 Regex library instead of Boost's, the result would be different.

On a Great Interview Question
Python uses backtracking, so this probably isn't O(n), especially with the ability to choose the dictionary.
But with there are non-backtracking matchers which would make this O(n). Here's re2 from https://github.com/google/re2 :

Regex: is there a difference between * and {0,}, as well as + and {1,}?

First release of SPVM::File::Spec - complex regular expressions, file tests, SPVM::Cwd, inheritance
I ported Google RE2, a regular expression library, to SPVM as Resource::Re2, and created SPVM::Regex, a wrapper for it.

SPVM::File::Basename is released. This is the first module of SPVM using regular expressions.
I searched for I found that there is a Perl compatible regular expression called Google RE2. It is written in C++, and with Google RE2, I can use Perl-compatible regular expressions as a library.

Ruby 3.2.0 Is from Another Dimension
Yes, but there is an interesting clarification here. RE2 has used the "caching" approach documented in the Ruby bug ticket linked for quite some time (since its birth?): https://github.com/google/re2/blob/954656f47fe8fb505d4818da1...
It is mentioned only briefly in Cox's article on regex matching in the wild. Look for the word "bitstate": https://swtch.com/~rsc/regexp/regexp3.html
I didn't know Perl had implemented this trick too.
The paper[1] cited in the Ruby bug ticket was published very recently. When I first read the Ruby bug ticket, I immediately wondered how they sidestepped the memory use problem. The paper's abstract seems to suggest there is some technique for doing so, as it rebuffs the idea of doing "full" memoization. Alas, I do not have access the paper. (Which is fucking ridiculous.)
