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.

Thinking about zero-allocation parsing.
Memory was not really designed for having lots of instances of it and doing intensive computations/searches on the instances. The reason for it is that Memory.Span property is actually quite expensive to call. Memory is a union type for storing strings, arrays, and even handles to native memory. Every time you construct it , slice it, or retrieve it's span, lost of machinery related to this union has to run. For example see the source for the Memory.Span property: https://github.com/dotnet/corert/blob/master/src/System.Private.CoreLib/shared/System/Memory.cs#L285.

Preview Features in .NET 6 - Generic Math
Yeah I know it's slower on its own, but I was sure it was handled as a faster intrinsic by the runtime. Went to double check and realized I was actually mixing things up with what CoreRT did (see here) but I guess it doesn't apply to CoreCLR. Would be surprised if there weren't any specific optimizations for this with .NET 6+ though, or at the very least with NativeAOT (given they've been porting some bits over from CoreRT and .NET Native too). Will need to go gather more info on this, as it's pretty interesting 🙂

> AOT compilation? I'll believe it when they'll release it, until then, it's all speculation
Devil's in the details, but there -is- AOT compilation[0]. While it hasn't been released as an official product, it has been used for a few projects including a commercial game [1]. And yes, they're looking into the next steps to make it a 'released' thing.[2]

What the F#
That is a well known issue, also what prevented F# to be properly used in .NET Native.
