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.
Why is Microsoft's C# not taught in most universities and Java is instead?
6 projects | reddit.com/r/microsoft | 15 Sep 2022
No, talking about C#, the language and it's accompanying runtime and class libraries, is completely open source now. The compiler Roslyn, (https://github.com/dotnet/roslyn) is open source and the language specification is now community driven (https://github.com/dotnet/csharplang).
Easier nullable reference types errors instead of warnings
2 projects | reddit.com/r/csharp | 24 Aug 2022
I hate to be that guy, but this has been an option since before Core 3.1: https://github.com/dotnet/roslyn/pull/30479, only a couple months after the release of C# 8.

2 projects | reddit.com/r/ItalyInformatica | 17 Jul 2022
C# e .NET sono entrambi open source e multi-piattaforma, girano su Windows, Linux, Mac, Android, iOS, WASM, etc. E il runtime supporta nativamente x86, x64, Arm, Arm64, e altri.
Is .NET open? MS pushing a proprietary extension to replace OmniSharp
12 projects | news.ycombinator.com | 16 Jun 2022
Ah come on! It's more complicated than that.
Most of the heavy lifting in OmniSharp is done by Roslyn . Roslyn is the open source C# compiler and code analysis library maintained by MS. You cannot overstate how much effort has gone into Roslyn, and how much money MS has invested to make it work. OmniSharp is essentially a wrapper around Roslyn (before Roslyn it was Mono), and while the OmniSharp team did a nice job developing a nice intellisense UX around it all, it is not like MS is taking it all away from them. Incidentally, it is almost certain that new intellisense plugin by MS will also be built on top of Roslyn.

In che linguaggio programmate principalmente?
5 projects | reddit.com/r/ItalyInformatica | 7 Jun 2022
...Che è completamente open source (incluse tutte le feature proposal e spec ufficiale) e che gira su un runtime che è anche quello completamente open source e anche multipiattaforma (incluso Linux, MacOS, Wasm, etc.)? 🙃
Unpopular opinion maybe but C# is getting too bloated
8 projects | reddit.com/r/csharp | 6 Jun 2022
If there are particular ones missing, you should feel free to open an issue on https://github.com/dotnet/roslyn/issues/new/choose8 projects | reddit.com/r/csharp | 6 Jun 2022
One of the least obvious complexities is in error handling. C# tends to give "good" diagnostics and will even help push you in the right direction at times. Consider for example that C# 11 is getting user-defined checked operators and so now public static T operator checked +(T left, T right) is now valid. One might assume that public static T operator unchecked +(T left, T right) is also valid, but it isn't. The compiler could spew 15 different errors about all the things it expected (commas, parentheses, binary operators, etc). Or it could fail gracefully and say "Unexpected keyword 'unchecked'": https://github.com/dotnet/roslyn/issues/60394

Lisp, Smalltalk, and the Power of Symmetry
2 projects | news.ycombinator.com | 29 May 2022
For me there was a huge divide between those who were supplying Smalltalk and worked that side of the fence, and the customers who were trying to solve problems. I saw that as why Smalltalk lost to simpler/arguably stupider tech like Java.
I have sometimes pondered whether to try making a system that kind of rhymed with Smalltalk, but using Roslyn instead. Although I envisage it as being a kind of playground where you code like Smalltalk, with the artifacts being produced as conventional class files and whatnot so the final build could be done with the normal command line tools.
