• You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use rails new first to generate all of the boilerplate files necessary.
• Create an app in the current directory with rails new .
• Use Tailwind CSS for styling. Use --css tailwind as an option on the rails new call to do this automatically.
• Use Ruby 3.4.2+ and Rails 8.0+ practices.
• Use the default Minitest approach for testing, do not use RSpec.
• Default to using SQLite in development. rails new will do this automatically but take care if you write any custom SQL that it is SQLite compatible.
• An app can be built with a devcontainer such as rails new myapp --devcontainer but only do this if requested directly.
• Rails apps have a lot of directories to consider, such as app, config, db, etc.
• Adhere to MVC conventions: singular model names (e.g., Product) map to plural tables (products); controllers are plural.
• Guard against incapable browsers accessing controllers with `al

## you presumably already know that this returns false, because of the way floats are stored:
0.1 + 0.2 == 0.3
# => false


# we can create a more useful way of comparing floats that matches what humans would expect:
class Float
  def =~(number, tolerance = 0.0001)

Ruby: The future of frozen string literals

What is a literal?

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

Some examples:

* vim is my remote editor of choice, and an acceptable local editor; and
