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.

1.56 Compile time is through the roof!?
To dig further into one specific rustc process called by Cargo, cargo +nightly rustc -- -Z self-profile -p some_crate https://github.com/rust-lang/measureme/blob/master/summarize/README.md

Reducing Rust Incremental Compilation Times on macOS by 70%
> When does the Rust compiler spend most of it's time? Is it at the checking stage?
rustc has a self-profiler that can be used to answer this question [0], as well as a mode that times each compiler pass [1].
There's no single reason the Rust compiler is slow, as it depends quite heavily on the code being compiled. For some codebases, LLVM code takes up most of the time; in other codebases (e.g., extremely generic-heavy codebases), it'll be checking-related passes.

My favourite Git commit (2019)
Not completely on topic (if you read TFA) but my favorite Git commit is by compiler badass and HN frequenter, where he checks in an entire C compiler to the D language repo:

The C Bounded Model Checker: Criminally Underused
A new generated code alone is 4000 lines long [1]. The actual code added is just 2000 lines, and some are used to pay debts, I mean, to make a proper code generator (which can be alternatively written in a simpler scripting langauge). In any case it is never comparable to the entier C parser proper.

OpenD, a D language fork that is open to your contributions
D is completely opensource already (https://github.com/dlang/dmd). The "open" of OpenD is just ADR saying that OpenD will be more open to new language features than D has historically been.

The OpenD Programming Language (fork of D)
The reference compiler, DMD, is open source: https://github.com/dlang/dmd
But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md
However, by some accounts, it's really hard to get anything through.
Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.
