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.

SDSL – Succinct Data Structure Library
> The currently active fork of SDSL (https://github.com/xxsds/sdsl-lite) has a BSD license.
How is that legally possible? As I understand, the GPL doesn't allow a derivative work to remove the copyleft provisions from the license.
Or maybe I misunderstood your comment?

SDSL-RS: A Rust interface for the C++ Succinct Data Structure Library.
This is awesome. As somebody who was actively involved in the development of SDSL I want to point out that https://github.com/xxsds/sdsl-lite is a more actively developed fork of SDSL with a more permissible license.

Manticore Search 5
Manticore Columnar Library uses Piecewise Geometric Model index, which exploits a learned mapping between the indexed keys and their location in memory. The succinctness of this mapping, coupled with a peculiar recursive construction algorithm, makes the PGM-index a data structure that dominates traditional indexes by orders of magnitude in space while still offering the best query and update time performance.
