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.

Blitsort: An ultra-fast in-place stable hybrid merge/quick sort
Blitsort is a hybrid quicksort, see title.
It is slower than it's unstable brother, aptly named crumsort. https://github.com/scandum/crumsort

Changing std:sort at Google’s Scale and Beyond
Any chance you could comment on fluxsort[0], another fast quicksort? It's stable and uses a buffer about the size of the original array, which sounds like it puts it in a similar category as glidesort. Benchmarks against pdqsort at the end of that README; I can verify that it's faster on random data by 30% or so, and the stable partitioning should mean it's at least as adaptive (but the current implementation uses an initial analysis pass followed by adaptive mergesort rather than optimistic insertion sort to deal with nearly-sorted data, which IMO is fragile). There's an in-place effort called crumsort along similar lines, but it's not stable.
I've been doing a lot of work on sorting[2], in particular working to hybridize various approaches better. Very much looking forward to seeing how glidesort works.
