Introduction

This challenge tests if you can locate the cause of a Rails issue in 5 iterations (script execution). Although it's a Rails issue, prior knowledge on Rails is not required.

The 5 iterations limit may feel constraining, but it is intentional. If you can't locate the cause within the limitation, that's totally fine.

After the challenge, there's a simple questionnaire. If you can answer the questions, it'll help me prepare my talk for RubyKaigi. Any feedback will be appreciated 🙏

I recommend allocating 1.5 hr for the challenge and the questions

[From: http://hanxue-it.blogspot.com/2018/08/macos-homebrew-installing-older-version-of-software.html - just created a copy to keep it for long term]

Homebrew  always wants to install the latest version of the Formula (software). This is by design, because every time there is an update to a formula, it wants to be tested against all the other formulas that it depends on. Mixing new and old versions of software is a recipe for incompatibility disaster. 

But sometimes there are situations where you need an older version of software. In my specific case, Yarn was compiled against an older version of icu4c, and I want that older version instead of recompiling Yarn.

Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.

Command Line Generator Info

Reference

You can get all of this information on the command line.

rails generate with no generator name will output a list of all available generators and some information about global options. rails generate GENERATOR --help will list the options that can be passed to the specified generator.

Suppose you have two heroku remote apps
myapp-dev & myapp-prod
and two git branches 
master(for dev) & production
Now lets setup heroku on the existing git repo in your local machine
Assuming the branches and the apps exist already
git remote add heroku-myapp-dev https://git.heroku.com/myapp-dev.git 
git remote add heroku-myapp-prod https://git.heroku.com/myapp-prod.git

Because I couldn't find these with a quick Google search on 28 April 2015:

Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]                                      # Path to the Ruby binary of your choice
                                                         # Default: /home/brian/.rvm/rubies/ruby-2.2.0/bin/ruby
  -m, [--template=TEMPLATE]                              # Path to some application template (can be a filesystem path or URL)
      [--skip-gemfile], [--no-skip-gemfile]              # Don't create a Gemfile

Running JavaScript from the command line

I get quite frustrated running JS by pasting into Chrome/FF and sometimes I like to keep everything local. These are some notes on using Apple's built in intrerpreter, node or phantom.

Using Apple's built in interpreter

Create a symlink by putting jsc into /usr/bin

sudo ln -s /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc /usr/bin

1. Use the jsc alias as a REPL
