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.

How to Design Better APIs
> * Human readable
Computers are the main consumers of APIs, and ISO 8601 is far from machine-readable.
For example, in Elixir, DateTime.from_iso8601/1 won't recognize "2022-03-12T07:36:08" even though it's valid. I had to rewrite a chunk of Python's radidjson wrapper to 1-9 digit fractional seconds (1).
I'm willing to bet 99% of ISO8601 will fail to handle all aspects of the spec. So when you say "ISO8601" what you're really saying is "our [probably undocumented, and possibly different depending on what system you're hitting] version of the ISO-86001 spec."

Benchmarking Python JSON serializers - json vs ujson vs orjson
For most cases, you would want to go with python’s standard json library which removes dependencies on other libraries. On other hand you could try out ujsonwhich is simple replacement for python’s json library. If you want more speed and also want dataclass, datetime, numpy, and UUID instances and you are ready to deal with more complex code, then you can try your hands on orjson

The fastest tool for querying large JSON files is written in Python (benchmark)
I asked about this on the Github issue regarding these benchmarks as well.
I'm curious as to why libraries like ultrajson[0] and orjson[1] weren't explored. They aren't command line tools, but neither is pandas right? Is it perhaps because the code required to implement the challenges is large enough that they are considered too inconvenient to use through the same way pandas was used (ie, `python -c "..."`)?
