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.
EXREX
- Generate text based on regex
-
Is there a PHP library that generates all possible matches for a simple subset of regex
or you could take exrex and port it to PHP
-
More advanced random option?
I'm able to use the python module/app exrex to do something like

Plan B for UUIDs: double AES-128
I really like ULID for this problem (e.g: https://github.com/ahawker/ulid)
- same number of bytes as UUID
- start with a date, so has great locality. Plus you get extra information in the uid that you can extract.
- can be created from an existing date or uuid, and exported to a uuid, so there is a migration path

New UUID Formats from IETF
As the author of a popular ULID implementation in python[1], the spec has no stewardship anymore. The specification repo[2] has plenty of open issues and no real guidance or communication beyond language implementation authors discussing corner cases. The monotonic functionality is ambiguous (at best) and is implemented differently per-languages [3].
Functionality, UUIDv7 might be the _same_ but the hope would be for a more rigid specification for interoperability.

Sortable Collision-Free UUIDs
Looks similar to ULID[0] (I am the author of a popular python implementation[1]).
It appears to have a similar constraint that two ID's generated within the same timestamp (ms, ns) have no strong guarantee of ordering. That might not be a deal breaker depending on your use case but something to consider.
