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.

Hey guys! Just wanted to share a tip on how to use performant Guid as primary keys in databases. Have you heard about UUID Version 7? It's here to save the day! Give it a try and let me know what you think. Happy coding! 😎💻
Here's the link to the library: https://github.com/mareek/UUIDNext

I need some help to adapt my UUID/GUID library (UUIDNext) to generate the best UUIDs for PostgreSQL, MySQL and other DBMS
I maintain a library that generate database optimized UUIDs and to investigate how UUID are stored and sorted on various databases, I need you to execute a little program that show just that (see end of post for more details).

BUT if you want to us GUID's on the server side as performant indexes, use this: https://github.com/mareek/UUIDNext

I need some help to adapt my UUID/GUID library (UUIDNext) to generate the best UUIDs for PostgreSQL, MySQL and other DBMS
I've created a library, UUIDNext, to generate next generation UUID/GUID based on the future RFC that will add new versions of UUID better suited for database use. UUID version 7 are guaranteed to be sorted contrary to traditional GUIDs (a.k.a UUID V4) that are random.

Short, friendly base32 slugs from timestamps
One simple workaround could be to use something like UUID version 7[0], using just the first part that encodes the time, and dropping the rest.
