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.

Backward compatible implementations of newer standards constructs?
For Variant I would recommend Michael Park's variant - mpark::variant
-
Is there an exception that I could throw if there is a path that should never run.
have a look at https://github.com/mpark/variant

An std::variant alternative for C++11
I know that there is boost::variant but adding the whole boot dependency for this use case seem too much. I have seen the following implementation and similar ones

How to implicitly convert between pointers and integral types
You could build your own versions if thats a concern. Or use one of the free pre-C++17 implementations (like I do in my C++11 codebase). https://github.com/mpark/variant

Using std::variant and std::visit to transform-reduce a (rose) tree
mpark::variant and mpark::visit are faster than the gcc STL implementation.

What is your preferred solution repeated nullptr checks on smart pointers
One could think of a more fluent interface to deal with smart pointers, similar to what exists in tl optional https://github.com/TartanLlama/optional

Assignment for optional<T>
It looks like tl::optional<>.

chessCAMO - chessCAMO is a newly proposed chess engine with a built-in variant that stands for Calculations Always Make Opportunities and was inspired by the very popular chess variant Crazyhouse. The "CAMO" portion comes from the idea that in this variant a player can sacrifice making a move to replace one of their pieces from the "piece reservoir".
