Weeknotes: 29 April to 3 May 2024

What I have found gripping

• Converting a Sqlite database into a PostgreSQL one in a Rails 7 project to ensure scalability and a better performance with a new approach can save time

• Deploying a web app and its database separately meant listing different variables in a YAML file beforehand

• Creating a list in Elixir can involve using the following

iex> book_list = ["Book A", "Book B", "Book C"]

• Storing a new value can look like this

iex> new = "Book D”

• Adding a new element to a list in Elixir includes the use of a pipe symbol

iex> [new | book_list]

iex> ["Book D", "Book A", "Book B", "Book C"]

Featured quote

At the heart of MVC, and the idea that was the most influential to later frameworks, is what I call Separated Presentation. The idea behind Separated Presentation is to make a clear division between domain objects that model our perception of the real world, and presentation objects that are the GUI elements we see on the screen. Domain objects should be completely self contained and work without reference to the presentation, they should also be able to support multiple presentations, possibly simultaneously. — Martin Fowler
