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.

In Defense of Linked Lists
I did this for an object pool in re2j and saw even single threaded performance improve.

Java doesn't suffer from pointer address ABA but I did have to handle reinsertion (except when the stack had only one element).

Some ECS implementations use this to reduce the overhead of dynamic arrays, as well as ensuring pointer stability of the items stored. For example entt:

And here's a library implementing a resizable, pointer-stable vector using virtual memory functionality from the OS:
