Could we distribute to world leaders Kubernetes HOWTOs or modern web stack tutorials so they get distracted and stop looking for confrontations?

In the last days I have counted breaths during meditation (zazen). Was curious about the rythm.
Turns out, I seem to do 10 every 4 minutes quite consistently. (Have done meditation for decades, with hiatuses.)
Also I often feel my heart beating, probably something related to increased vagal tone.

The post has some stereotypes, but essentially there's truth there.
A good novel takes you to other places, in a broad sense of the word. And that is an experience in itself.

And this equally applies to conference talks. You need a story and not just release notes.

I was recently reminded that not everyone fully understand what the frozen string literal magic comment is about.
So I figured it was the occasion for another deep dive.

Frozen String Literals: Past, Present, Future?
If you are a Rubyist, you’ve likely been writing # frozen_string_literal: true at the top of most of your Ruby source code files, or at the very least, that you’ve seen it in some other projects.

Rails 8.1 ships with a feature I wrote for Gusto as a monkey patch they decided to contribute: the ability to deprecate an association.
This is a first. Consulting is separate from OSS for me, access to Rails is not part of my value proposition, and I do not pursue "being paid for doing OSS".

I use a modified version where I set `$debug` in a test causing an issue, then check it in the code to put debugging info
Debug technique I use in some occasions:
Define global variable $foo where you collect stuff, maybe in different places.
Then, at_exit { pp $foo }.

Generally speaking, ancestor chains do not belong to public interfaces.
Say, if an instance of Foo::Bar provides method `foo`, generally speaking, whether the method comes from the class or a mixin is not a concern of the user. That, and the module constant, do not belong to the public contract.

To use an API, or read source code, you need to know what do methods accept and return.
And that is orthogonal to dynamic typing.

Correction: RBS itself supports interfaces, it is inline RBS what I had in mind.
YARD has notation for duck typing, and in Zeitwerk I made up my own (see for example these two attributes github.com/fxn/zeitwerk...)

The main limitation I find in RBS is that it does not support duck typing interfaces, so common and idiomatic in Ruby.
