MiniMath
MiniMath is an experiment to create different math functions using a single line of Python code using only built-in functions.
I've used this recently to do some fuzzy matching of column names in datasets, I also added it to a small python one-liner library I've been making for practice. p.s. don't give me flack, I know this isn't an efficient way to do things.
jaccard = lambda A, B: len(set(A).intersection(set(B))) / len(set(A).union(set(B)))

RoaringBitmap
A better compressed bitset in Java: used by Apache Spark, Netflix Atlas, Apache Pinot, Tablesaw, and many others
As an aside if you find yourself having to compute them on the fly, know that the Roaring Bitmaps libraries is the way to go [1]. The bitmaps are compressed, and can be streamed directly into SIMD computations (batching XORs and popcnts 256 bits wide!). The Jaccard index is just intersection_len / union_len [2] away
