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.

Ask HN: What are some 'cool' but obscure data structures you know about?
The BK-Tree, which allows fast querying of "close" matches, such as Hamming distance (number of bits different). http://blog.notdot.net/2007/4/Damn-Cool-Algorithms-Part-1-BK...
I wrote a Python library implementing them a number of years ago: https://github.com/benhoyt/pybktree

Near duplicate image detection
Now let's compare the hash to all the image hashes using Levenshtein distance. We'll use the textdistance library for that.
- life4/textdistance: Compute distance between sequences. 30+ algorithms, pure python implementation, common interface, optional external libs usage.
