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.

Databases = Frameworks for Distributed Systems
Tarantool is an application server for distributed systems written in Lua. Lua applications launched in Tarantool have API access to the following components:

Ten-year experience in DBMS testing
In 2020, we added support for synchronous replication and MVCC. We had to test this functionality, so we decided to write some tests powered by Jepsen framework. We check consistency by analyzing the transaction history. But the story about testing with Jepsen is big enough for a separate article, so we'll talk about it next time.

Frawk: An efficient Awk-like programming language. (2021)
gron (https://github.com/tomnomnom/gron) to transform it and query and then invert the transformation?

Make JSON Greppable
It buffers all of its output statements in memory before writing to stdout:

Jaq – A jq clone focused on correctness, speed, and simplicity
Have you tried `gron`?
It converts your nested json into a line by line format which plays better with tools like `grep`
From the project's README:
▶ gron "https://api.github.com/repos/tomnomnom/gron/commits?per_page..." | fgrep "commit.author"
json[0].commit.author = {};
json[0].commit.author.date = "2016-07-02T10:51:21Z";
json[0].commit.author.email = "[email protected]";
json[0].commit.author.name = "Tom Hudson";

It was suggested to me in HN comments on an article I wrote about `jq`, and I have found myself using it a lot in my day to day workflow

Interactive Examples for Learning Jq
> So all I want is a tool to go from json => line oriented and I will do the rest with the vast library of experience I already have at transformations on the command line.*
The tool for that is likely https://github.com/tomnomnom/gron

Modern Linux Tools vs. Unix Classics: Which Would I Choose?
If JQ is too much, see GRON &| Miller
gron transforms JSON into discrete assignments to make it easier to grep for what you want https://github.com/tomnomnom/gron
Miller is like awk, sed, cut, join, and sort for data formats such as CSV, TSV, JSON, JSON https://github.com/johnkerl/miller
- XML is better than YAML

jq 1.7 Released
And jless [1] and gron [2].
This is the first I'm hearing of gron, but adding here for completeness sake. Meanwhile, JSON seems to be becoming a standard for CLI tools. Ideal scenario would be if every CLI tool has a --json flag or something similar, so that jc is not needed anymore.
