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.

Pratt Parsers: Expression Parsing Made Easy
Ha, nice to see this on HN: this article was pretty helpful to me to understand the concept a few years back when extending my PEG parsing library [1] with a Pratt parser; this mitigates the problem of PEG parsers not allowing left recursion and allows for a much more concise notation of grammars with operator precedence. Thank you Bob:

Nim v2.0 Released
Nim's default json library is terrible in performance, but there're much faster drop-in replacements like jsony[1]. I'm not sure that's the main issue for low rank, but it's definitely one of them.

Why I enjoy using the Nim programming language at Reddit.
One of the fastest things I have written in Nim is a JSON parsing library. Why is it fast? Well, it uses Nim’s metaprogramming to parse JSON directly into typed objects without any intermediate representations or any unnecessary memory allocations. This means I can skip parsing JSON into a dictionary representation and then converting from the dictionaries to the real typed objects.

Nim vs Python: json serialization performance
The nim stdlib's json(due to how it works) is relatively slow. Jsony Jason are some alternatives that are more performant and speeeedy.
What are some alternatives?
