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.

Pinecone raises $100M Series B
Why do you use pgvector instead of pgANN? My understanding is pgANN is built with FAISS. When I compared pgvector with FAISS, pgvector was 3-5x slower.

Pgvector – vector similarity search for Postgres
Love it! Need better ANNs approaches in databases, using external servers such as Milvus, faiss is a pita

DiskANN Implementation in Rust + Easy NN Search
Hi! I have been noodling away at a re-implementation of the original C++ DiskANN project as well as packaging the latest advances in embedding generation. The rough repo is here and will remain licensed as Apache-2.0!

Pinecone raises $100M Series B
Spot on. There is zero moat and the self-hosted alternatives are rapidly improving (if not better) than Pinecone. There are good open-source contributions coming from bigcorp beyond Meta too, e.g., DiskANN (https://github.com/microsoft/DiskANN).
