The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

The same approach as my Python solution — for each row, it tracks the left-most and right-most seen point for each sensor. Then it searches if there has been a gap between two sensors.

In the end, my solution, especially in the game logic part, is heavily based on the stuff you did.

But to be honest, I like my Clojure solution even more.

Advent of Clojure - looking for feedback
Regarding hashing, custom hash functions even for records (if all fields are longs for example) can help substantially if you are hashing points some notes here. Even then, depending on what you are doing, you may be better off using a primitive numeric representation and a dense collection (e.g. a primitive array) since the mechanical sympathy may be substantial. It is also possible to do well using nested maps (particularly for memoization) when the pieces of a compound key are already trivially hashed. E.g. clojure.core/memoize just defines a varargs wrapper around a function and caches the sequence of args in a map. For earlier reasons, this is a poor strategy for many functions and performance can be substantially improved (e.g. for a 1 or 2 arg function of numbers or keys or strings even) if we defined fixed arity paths that store keys in nested maps instead of hashing complex collections.
