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.

ASTs in Ruby - Node Pattern and Introducing RuboCop
Oh, and that regex bit? Remember how we have Rubular for regex? We have the NodePattern Debugger for ASTs which you will find incredibly helpful, in fact you might open it now and try out some of these examples to make sure I'm not pulling a Fast one. (No, I'm not apologizing for that one.)

Future of Ruby – AST Tooling
Some of these tools have even already been wrapped, like Jonatas's work on FFast which works on top of NodePattern and some of RuboCop's previous work. Really the only things between us and this future is a bit more wrapping and polish, as well as integrations into something like VSCode.

Hierarchical Structures in PostgreSQL
I'm actually using materialized views and CTE with PhotoStructure (where hierarchies are arguably the cornerstone of the product).
It's pretty funny that I landed on this implementation, given that I spent a couple years building https://github.com/ClosureTree/closure_tree (one of the most popular acts-as-hierarchy ActiveRecord gems), as it (unsurprisingly) uses closure trees.
When CTE isn't available, closure trees are nice, but boy howdy, does that closure tree table get gigantic with deeper graphs.
If CTE is available, closure trees don't even come close in performance and simplicity.
(Hint: materialized paths should use a unique separator: ASCII 0x1F is applicable: https://en.wikipedia.org/wiki/C0_and_C1_control_codes#Field_...)
