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 UX of UUIDs
https://github.com/uuid6/uuid6-ietf-draft/issues/27

This is very cool! I love this solution for ID’s what do you all think?
Why not UUIDv7?

UUIDs Are Bad for Database Index Performance, enter UUID7!
What if a new UUID version could be designed that would take the randomness of UUID4 and combine it with a timestamp prefix? This would make the UUID increase overall, but not locally – due to the random postfix. The random part ensures uniqueness when a high generation rate is necessary and also makes the UUIDs hard to predict – it’s not possible to guess the previous, or next UUID. It’s fairly simple to devise a custom UUID scheme, but fortunately, there is a new Internet-Draft (at the time of writing) defining new pseudo-sequential UUID versions that aim to solve exactly this issue: draft-peabody-dispatch-new-uuid-format-04. The current state and progress can be viewed at IETF Datatracker.

Understanding UUIDs, ULIDs and String Representations
Brad Peabody did the original -00 draft, which was discussed as an FYI at an IEFT meeting in March 2020. See [1], around 50 lines from the bottom.
Kyzer Davis has since submitted two further revisions -01 and -02 in April and October 2021. See history in [2].
The current -02 draft is due to expire in April 2022. Presumably Kyzer Davis will try to get it discussed before then.
The GitHub repo tracking these drafts is https://github.com/uuid6/uuid6-ietf-draft/.

- UUID version 7. It's binary sortable and has many other advantages. Created specifically for modern distributed systems. IETF draft is published, they mid tweaking before publishing v3 draft.

New UUID Formats – IETF Draft
At the moment anyway, that XML link won't render per an XML parsing error. For anyone who wants a quick look at what these XML docs look like here's one for UUID6 [0].

How to use performant Guid as primary keys in databases. UUID Version 7 to the rescue!
Side note, an interesting thing to add to your benchmarks would be ULID https://github.com/Cysharp/Ulid

New UUID Formats – IETF Draft
I’m using Postgres so I actually have it a little easier with its native sort order. I switched from NUlid that I was using from years back to this one [0], and the default .ToGuid() gets the desired sort order when used with Npgsql. Likewise though, no db-side generation of uuid - then again, isn’t that the benefit of using globally unique identifiers in the first place, to avoid needing to rely on the db to generate conflict-free identifiers, skipping HiLo or sequences, etc.
Anyway, nice to meet another .NET Ulid user in the wild!
