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.

Small sum types in Golang
I find this implementation to be quite minimal and less clumsy than alternatives. Sure, you don't get nice exhaustive pattern matching. Also, type inference gets in the way when instantiating UserKey (though you can wrap it in constructor functions). But expressing your intent using types still makes your code much more convenient and easier to understand.

Switching from C++ to Rust
The call out to sum types is something I feel. I've been using Rust daily for almost 10 years now, and sum types are absolutely still one of the things I love most about it. It's easily one of the things I miss the most in other languages. I'm usually a proponent of "using languages as they're intended," but I missed exhaustiveness checking so much that I ported a version of it to Go[1] as a sort of lint.

Carbon Language: An experimental successor to C++
I've been writing Go and Rust nearly daily for about a decade now (Go is more than a decade, Rust is about 8 years). You are not going to teach me anything about the pros and cons of either language in a reddit comment. I do not need to be taught about the "iota mess" when I've written tooling for exhaustiveness checking in Go.

https://github.com/BurntSushi/go-sumtype forces exhaustive type switches for interfaces specifically annotated to need that.
