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.

Is anyone using PyPy for real work?
If you have very large dicts, you might find this hash table I wrote for spaCy helpful: https://github.com/explosion/preshed . You need to key the data with 64-bit keys. We use this wrapper around murmurhash for it: https://github.com/explosion/murmurhash
There's no docs so obviously this might not be for you. But the software does work, and is efficient. It's been executed many many millions of times now.

Data Ingestion - Build Your Own "Map Reduce"?
Some notes: We don't need Sha256 and not evey base64; nothing will happen if keys will not distribute very equally. we could take MMH3; googling "python murmurhash" gives 2 interesting results; and since both use the same cpp code, let's take the one with most stars Other options would be to simply do (% NUM_SHARDS) or even shift right (however must have shards count == power of 2).
