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.

Rob Pike: Gobs of data (2011)
Someone made a benchmark of serialization libraries in go [1], and I was surprised to see gobs is one of the slowest ones, specially for decoding. I suspect part of the reason is that the API doesn't not allow reusing decoders [2]. From my explorations it seems like both JSON [3], message-pack [4] and CBOR [5] are better alternatives.
By the way, in Go there are a like a million JSON encoders because a lot of things in the std library are not really coded for maximum performance but more for easy of usage, it seems. Perhaps this is the right balance for certain things (ex: the http library, see [6]).
There are also a bunch of libraries that allow you to modify a JSON file "in place", without having to fully deserialize into structs (ex: GJSON/SJSON [7] [8]). This sounds very convenient and more efficient that fully de/serializing if we just need to change the data a little.

A similar project: https://github.com/tidwall/sjson
- Modification of json string without deserialisation into map/struct
- Need help on appending fields to json bytes

Anyone learning Go or building a side project?
Not sure what you need to do but there is https://github.com/tidwall/sjson for quick manipulation.

What are your favorite packages to use?
I love https://github.com/tidwall/gjson and https://github.com/tidwall/sjson for fast and frictionless json reading and editing. It makes life so much easier for cases where you don't want to model a tree of nightmare-ish API responses, like Elasticsearch.
