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.

C++ DataFrame vs. Polars
For a while, I have been hearing that Polars is so frighteningly fast that you shouldn’t look directly at it with unprotected eyes. So, I finally found time to learn a bit about Polars and write a very simple test/comparison for C++ DataFrame vs. Polars.

C++ Show and Tell - July 2023
I have worked on C++ DataFrame for the past 5+ years in my spare times. It is comparable to Pandas or R data.frame, although it includes a lot more functionality.

Introducing The C++ DataFrame for data analysis
Just to be clear, DataFrame is not a matrix. It is a data-frame. If you want a fast C++ matrix you can take a look at https://github.com/hosseinmoein/Matrix
