During the last days I have done an immersion into namespaces, the new big feature that is coming in Ruby.
Here's a digested mental model for you all.

How would you implement the Observer pattern — similar to pub-sub — in Ruby? Well, there's a module right in the standard library that does it for you!
It's a little quirky with its dirty tracking, but that might be just what you need.

![A screenshot of Ruby code showing the standard library's observer pattern in use. The code is as follows:
require 'observer'
class Plumber
include Observable
def initialize
@coins_collected = 0
end
def collect_coin
@coins_collected += 1
# mark this object as dirty; this is required for notification to actually happen.
changed
notify_observers(:coin_collected, total_coins: @coins_collected)
end
end
class AchievementEngine
def initialize
@hundred_coins_achievement_unlocked = false
end
# this will be called by notify_observers
def plumber_updated(status, params = {})
case status
when :coin_collected
plumber_collected_coin(params[:total_coins])
end
end
def plumber_collected_coin(total_coins)
puts "Collected another ten coins! Total: #{total_coins}" if (total_coins % 10).zero?
return if total_coins < 100 || @hundred_coins_achievement_unlocked
puts 'Achievement unlocked: collected 100 coins!'
@hundred_coins_achievement_unlocked = true
end
end
class Game
def initialize
@plumber = Plumber.new
@achievement_engine = AchievementEngine.new
# Register achievement engine as an observer and call `plumber_updated` on it when
# plumber's observers are notified
@plumber.add_observer(@achievement_engine, :plumber_updated)
end
# simulates some iterations of a gameplay loop, in which the plumber collects
# a random number of coins.
def start
10.times do |i|
puts "Iteration #{i.next}"
coins_to_collect = rand(5..25)
coins_to_collect.times.each { @plumber.collect_coin }
end
end
end

RFK Jr.'s rhetoric on autism is deeply rooted in eugenics, which at its core is a proposition that some lives are less valuable than others.
Within the last week I've heard from folks back home that I'm overreacting because I'm "one of the good ones."

Today I played a bit modelling multi-step workflows with #ruby, #eventsourcing and reactive UIs.
In this (ugly AF) demo, the UI reacts to state updates, which are all eventually-consistent and run in the background. No code difference between "controllers" and "background" jobs.

The idea is to keep the basic structure of the book the same while updating it to Ruby as it is used today.

The Tulsa Race Massacre was not committed by an uncontrolled mob but was the result of “a coordinated, military-style attack” by white citizens, the Justice Department said in a report. It was the first time the U.S. government has given an official account of the 1921 massacre of Black residents.
Tulsa Massacre Was a ‘Coordinated, Military-Style Attack,’ Federal Report Says
The Justice Department’s conclusion follows an investigation of the 1921 atrocity in Oklahoma in which up to 300 Black residents were killed.
