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.

Amazon Ion Specification
What's the pros and cons of this versus CBOR, which we had great success with in our system.

Compressing GraphQL Global Node ID
CBOR (Concise Binary Object Representation) is a codec for small JSON object, similar to MessagePack but in the internet standard.
-
Why is json logging the “standard”?
JSON is a simple key=value pair representation. If you want to implement it by your hand with the same set of features (maps, lists, character escaping) then you will get something really similar. They are binary alternatives like https://cbor.io/ , but they are not popular for same reasons we use human readable representation of data for any other use case in programming

Alternatives to JSON and gjson as a document datastore?
Maybe this? http://cbor.io/ Haven't used it personally but I've read good things about it and the documentation makes sense.

go-cose: CBOR Object Signing and Encryption
go-cose is the Go implementation of COSE. COSE is a signing and encryption format based on the Concise Binary Object Representation format (CBOR). While inspired by the needs of the IoT community including fast processing on low-memory devices, the format is broadly applicable from small devices to large-scale server environments. COSE has incorporated lessons learned from Javascript Object Signing and Encryption (JOSE) efforts including JSON Web Signature (JWS) and JSON Web Token (JWT).

MQTT lightweight variable payload
Have a look at cbor, https://cbor.io/ It's very compact and works wonderfully for embedded devices. Works identical to Json but than for binary data.
-
JSON Storage Efficiency
You could also look into CBOR serialization format. It's less readable but it's much more efficient than JSON.

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.

Jj: JSON Stream Editor
```
I don't think there is a way to sort an array, though. However, there is an option to have keys sorted. Personally, I don't think there is much annoyance in that. One could just pipe `jj` output to `sort | uniq -c`.

Library to analyze an arbitrary JSON string
I’m using GJSON, so far so good!
-
Mapping json fields in api calls to a struct to store them in a database or cache
If the fields you need are just a small subset of the whole json, maybe https://github.com/tidwall/gjson might be of use to read only those (using jsonpath) without needing to create complete corresponding structs.

Which CPU to buy based on profiling
Thank you for the reminder, it's never too much of it :) Didn't say it, but the code was pprof-iled many times and i can really say it's well optimized. I use own libraries with on-the-fly equations (sums, avgs, emas, stds, ...) wherever possible and also made custom json parser as json messages are in fixed format, so the parser is about 10x faster than gjson. I optimized it to the point that I avoided using maps, and rather iterate via slice where ever possible.

Jetro - transform and query JSON format
You are right, for learning purposes this fit my needs, but I can imagine an approach similar to this repo: https://github.com/tidwall/gjson

Any way to convert unknown/dynamic json to generic object structure
https://github.com/tidwall/gjson is a relatively sensible library if this is something you need to deal with and the structure is actually unknowable.
