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.

Example of Entity Component System in Go
Good question, I think there's many different lessons. To your point about bitmasks, you can imagine that each component (i.e. column) has an array of data and a large bitmap that identifies whether a component is present or not. Had to build a SIMD implementation so you can do and, and not, or and xor operations on millions of components within reasonable amount of time. Interestingly enough, you still need a hashmap or b+tree in case you want to retrieve a component by it's ID instead of an index, but the rest of things can be modeled with bitmap indexes.
What are some alternatives?
When comparing set and bitmap you can also consider the following projects:
hyperloglog - HyperLogLog with lots of sugar (Sparse, LogLog-Beta bias correction and TailCut space reduction) brought to you by Axiom
fsm - Finite State Machine for Go
trie - Data structure and relevant algorithms for extremely fast prefix/fuzzy string searching.
go-adaptive-radix-tree - Adaptive Radix Trees implemented in Go
bitset - Go package implementing bitsets
gota - Gota: DataFrames and data wrangling in Go (Golang)
null - Nullable Go types that can be marshalled/unmarshalled to/from JSON.
roaring - Roaring bitmaps in Go (golang), used by InfluxDB, Bleve, DataDog
go-geoindex - Go native library for fast point tracking and K-Nearest queries
