TIL about ActiveSupport inflections. Sometimes Rails gets pluralization wrong - for me, this happened with 'Bonus'. Try creating a model with that name and watch what happens 🙃
It's easy enough to fix, with the right initializer.

Nobody uses Ruby on Rails anymore? The data suggests otherwise 🙃
Crunching some data from rubygems.org gives you Rails gem downloads per year. Doesn't look like it's going down to me.

Whenever I get a new laptop, I feel the irresistible urge to improve my setup. You know, tweaking the ol' Vim config, maybe creating a script or two to automate a few things.
It's not a rabbit hole to get lost in at all.

Source code is just plain text.
A parser transforms it into expressions that can be evaluated by an interpreter.
Expressions form the basic building blocks of methods and objects.
Objects send messages to each other, and process the messages they receive via their methods.

Maybe github.com/standardrb/s... address this, by offering a non-configurable style config.
I haven't looked at the rules in detail though. Will definitely give it a try soon

It is NOT taking our jobs any time soon lol. The complexity of software will only increase with AI-driven programming and actual human interventions will be required 🙃
