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.

New UUID Formats from IETF
Nice to see another implementation which takes a bit different approach. Just for your information, there's now Draft 03 which changes the format a little bit. I kinda liked the arbitrary precision of Draft 02, but the newer one just requires millisecond precision and then basically leaves it up to the implementation how to handle the generation of multiple UUIDs within the same millisecond.

Sequential UUID in snowflake
Snowflake does not support UUID 7. What you could do is import UUID7 Python module and implement a Python UDF.

Understanding UUIDs, ULIDs and String Representations
To summarise the differences:
* UUIDv6 - sortable, with a layout matching UUIDv1 for backward compatibility, except the time chunks have been reordered so the uuid sorts chronologically
* UUIDv7 - sortable, based on nanoseconds since the Unix epoch. Simpler layout than UUIDv6 and more flexibility about the number of bits allocated to the time part versus sequence and randomness. The nice aspect here is the uuids sort chronologically even when created by systems using different numbers of time bits.
* UUIDv8 - more flexibility for layout. Should only be used if UUIDv6/7 aren't suitable. Which of course makes them specific to that one application which knows how to encode/decode them.
UUIDv7 is thus the better choice in general.
