For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.

# A script to migrate Sidekiq's redis to a new server.

Add the following to application.rb:

$icallbacks = []
$icallbacks.define_singleton_method(:print) do
  puts sort_by { |(a, b)| -b }.map { |(a, b)| "#{b}\t\t#{a}" }.join("\n")
end

ActiveSupport::Notifications.subscribe("load_config_initializer.railties") do |event|
 $icallbacks << [event.payload[:initializer], event.duration]

Naming guidelines

1. Syntax

1.1 Be consistent

Consistency in naming makes reading and memory retrieval much, much easier. Conversely, changing rules and mixing conventions are very confusing and significantly increase cognitive load. Follow language, company, and project conventions for names, even if you don't like them.

1.2 Follow conventions

With Docker Desktop becoming more restricted, I've decided to move on to just using minikube. In doing so, I've consolidated my notes as follows.

Installation

Use brew to install the docker cli and minikube.

$ brew install minikube docker kubectl hyperkit

Running Minikube

The first time you start minikube, you should specify any settings you desire.

Day 0 - Bootstrap MacOS with Ansible

After factory resetting the maching you will need to do the following things to bootstrap it with Ansible.

• Set default shell to bash chsh -s /bin/bash (optional)
• Open the App Store and sign in (but do not install anything)
• Install command line tools
  • xcode-select --install
• Add Python 3.8 to the $PATH
• export PATH="$HOME/Library/Python/3.8/bin:$PATH"
