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.

A Bit Overcomplicated
At the risk of sounding stupid, I have no idea how bit-shifting and bitwise operators work, though I've worked in the field for over a decade and am now a Staff Engineer or whatever. There, I said it.
It's just something I haven't gotten around to reading yet. I suspect some code would be made clearer by it, but even when doing something similar I wound up using the math textbook was to do it even though I suspect the bit operators would be much faster.

New UUID Formats – IETF Draft
Yeah, it's a small world.
I actually took the opposite path and explored several of the micro-optimized ULID libraries in C# before settling down with NUlid which I decided had the cleanest API and documentation (and reasonably good response times to GitHub issues). The implementation of Cysharp's lib has a lot of Unsafe code, which I understand why they took that path (given the focus on Unity code), but I'm hesitant about it and I liked a lot better (conceptually) how much more Span code mcb2001's CSharp.Ulid library had and if I were to micro-optimize a library that's much more the path that I would take. (But so far micro-optimizations of that sort haven't been a priority in my real world usage and I'll take the well tested library with the nice API.) I created a couple simple extension methods to do the specific "ToSqlGuid()" and "ToUlidFromSql()" that I desired for the SQL Server sort order. (Which is just shuffling the first six bytes of a ULID byte array to the end of the GUID byte array and vice versa.)
I actually trust that I can at least generate ULIDs in SQL Server, again because the part I care to be sorted/needs to be correct (the timestamp) fits into the non-endian-issue portion of a GUID in SQL Server. I've been using just the generator function from ulid-mssql [1] (I used it mostly just for DB migrations and it was nice to have for that). It was debugging the endian issues and Base-32 encoding issues of the "ULID GUID to string" functions where I gave up and decided I didn't trust doing that in database.
