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.

I have some questions about defining a series of bits in Golang
For (3), and if you’re interested in checking if specific bits are set or not, take a look at https://github.com/bits-and-blooms/bitset and https://github.com/RoaringBitmap/roaring.
- Bitmasks - how and why to use?
-
Skipfilter
Each topic has a roaring bitmap. Each bit corresponds to a subscriber in the skip list. For each topic, head and tail cursors are also maintained to ensure that newly added subscriptions are always tested and deleted subscriptions are always evicted. Roaring bitmaps are compressed and discontinuous so memory usage again remains bounded as subscribers come and go.

Bit shifting blew my mind
Definitely take a look at a roaring bitmap. https://github.com/RoaringBitmap/roaring

Protocol buffers database, a Key-Value database on the wire
Roaring bitmaps + btrees are a rock solid indexing approach. Alternatively, bleve has a lot out of the box but that's introducing a new datastore, basically.

Is there something similar to blessed.rs ?
If it were true, there wouldn't be any 3rd-party libs for Go and everybody used just the stdlib. For instance, if you need a set, you can use https://github.com/deckarep/golang-set . Of course, you can do it with the stdlib with map, but if you don't want to do that, use golang-set . I think Python has a much larger stdlib and yet, Python has tons of 3rd-party packages.

Any major projects using generics?
golang-set is a set implementation used by docker, ethereum and others. 2.8k stars on GitHub. Pretty popular project. Not sure if it counts as major. https://github.com/deckarep/golang-set
- When will Go get sets?
-
Does anyone else get tired of the "that's trivial to implement" excuse for leaving things out of the standard library?
Why not look at something like https://github.com/deckarep/golang-set ?

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

Major update to the golang-set repo now supporting generics syntax for Go 1.18beta1 release
This pre-release only exists on the generics branch at: https://github.com/deckarep/golang-set/tree/generics. Eventually this release would be tagged with a 2.0 release tag name.
