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.

q_compress 0.7: still has 35% higher compression ratio than .zstd.parquet for numerical sequences, now with delta encoding and 2x faster than before
I also had a quick look and compared it against the X3 protocol (similar to FLAC, but more lightweight). q_compress works well in some cases (very low noise and very high noise), while X3 does better in the middle.

How do Games manage NPC schedules?
I use a fake database paired with compressed bits for flags and integer compression for various other traits. They follow a navigation guide similar to wind for foliage.

Quantile Compression: 35% higher compression ratio for numeric sequences than any other compressor
It could be nice to see a comparison against https://github.com/powturbo/TurboPFor-Integer-Compression !

q_compress 0.7: still has 35% higher compression ratio than .zstd.parquet for numerical sequences, now with delta encoding and 2x faster than before
I'm the author of TurboPFor-Integer-Compression. Q_compress is a very interresting project, unfortunatelly it's difficult to compare it to other algorithms. There is not binary or test data files (with q_compress results) available for a simple benchmark. Speed comparison would also be helpfull.
