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.

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.

(Don't) crank up the warnings to 11
The PR in question seems to be https://github.com/RoaringBitmap/CRoaring/pull/446
I agree that the GitHub analyses are worse than useless, but I also think it highlights the friction between intrinsics and the program in which they appear. There probably is a better model.

Progress in building an 100% rust lang program.
Installation completed the program build successfully!! https://www.reddit.com/r/openbsd/comments/yux513/comment/iwbm72c/?context=3 I configured 2 different files in .cargo (thanx @ivan_linux for https://github.com/RoaringBitmap/CRoaring/pull/412) and .profile ( https://rust-lang.github.io/rust-bindgen/requirements.html#openbsd ) But when I try to start the program unfortunately the node not starting and I get the following errors.
- I will need your help to complete (if possible) a rust lang program installation
- What std::bitset could have been

Help with CFFI, C struct decoding, best practices / portability
I've been using CFFI to access the CRoaring C API to Roaring Bitmaps. It's been pretty easy so far. However I'm not experienced in lisp FFI, and I'm unsure of the way to go about the task of decoding a C structure used for iteration in the C CPI. The structure is as follows: ``` typedef struct roaring_uint32_iterator_s { const roaring_bitmap_t *parent; // owner int32_t container_index; // point to the current container index int32_t in_container_index; // for bitset and array container, this is out // index int32_t run_index; // for run container, this points at the run

FFI advice sought
I have a build shared library build of the C API for Roaring Bitmaps and I'm just trying to figure out the right path forward to write a lisp interface to it on sbcl.
