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.

Updating map_benchmarks: Send your hashmaps!
Also, I'm testing https://github.com/greg7mdp/sparsepp which is based on google's sparsehash

Who here is ready to see some 64MB blocks on mainnet?
Hey thanks for the mention /u/jtoomim. I see that you used sparsepp in CoinsViewCache. A phmap::flat_hash_map would probably be similar for memory usage, but likely faster (because of parallel lookup with SSE instructions and contiguous memory storage in one array).
What are some alternatives?
