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.

Go 1.18 Released
It depends on the level of abstraction you're addressing. One level may be "i need to store things with a quick search function", another may be "i need a storage of ordered names and expiry date for things", etc until you get to "I need a binary tree which orders by comparable types".
Where you split that process as a separate library you either decide to write or reuse - that becomes the problem to solve. A set implementation may be a problem to solve: https://github.com/deckarep/golang-set A btree may be a problem to solve: https://gitlab.com/cznic/b/-/tree/master/v2

Requires Go1.18beta1 or later: https://gitlab.com/cznic/b/-/tree/master/v2

Go 1.18 Released
>> By introducing a single generic, you could reduce it from 500 lines to 20
No one is writing 500 lines of code - just as when you use the generics syntax you don’t write the code that is generated by the compiler in response.
You could save about 10 lines, specifically these 10:
https://github.com/logic-building/functional-go/blob/master/...
You would still need the comparable ~40 lines of “generic” code:

-
Do you see any interesting use cases for the upcoming type sets, other than generic type constraints?
Yes! There is this library that uses go generate for achieving functional patterns https://github.com/logic-building/functional-go. It would really benefit from such thing.
