Go - The Ultimate Folder Structure

Organizing your Go (Golang) project's folder structure can help improve code readability, maintainability, and scalability. While there is no one-size-fits-all structure, here's a common folder structure for a Go project:

project-root/
    ├── cmd/
    │   ├── your-app-name/
    │   │   ├── main.go         # Application entry point
    │   │   └── ...             # Other application-specific files

Ruby jemalloc

Adding jemalloc via `LD_PRELOAD`

FROM ruby:3.2-slim

RUN apt-get update ; \\
    apt-get install -y --no-install-recommends
      libjemalloc2 ; \\

These instructions set up a way to publish tweets to Twitter's OAuth2 API from a Ruby on Rails app.

Set up a twitter account via the Twitter account setup instructions here: https://github.com/jkotchoff/twitter_oauth2#twitter-account-setup
Add the twitter_oauth2 gem and something to issue HTTP requests (like Typhoeus) to your Gemfile:

gem 'twitter_oauth2'
gem 'typhoeus'

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.
