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.

GeoHash lib in C++17
- No allocations, no std::string - Optimization of nearby cells - GeoHash::nearbyCells() - Different units and "geo-spheres". Theoretically can work on the Moon and any other planet. - Demo usage in main.cc - Suppose to be part of HM4 (https://github.com/nmmmnu/HM4)
- C++ Show and Tell - July 2023
- What are some C++ projects with high quality code that I can read through?
-
I voluntarily tried to copy a string into an insufficiently long memory space but the compiler did not return any error
In some real situations, you may want to overwrite next variables. For example if this was a C struct - I have code similar to this here - https://github.com/nmmmnu/HM4
DataFrame
- New multithreaded version of C++ DataFrame was released

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.
- Allocators; one of the ignored souls of STL
