Let's face it, Ruby is slow , but don't abandon Ruby just yet. Using extensions, we can write performant code in another language for the specific slow functions while the rest of the application remains untouched.

In this episode, we look at creating ruby objects. Then we look at different ways of implementing memoization and how it can be used to speed up our classes.

Continuing from the previous episode, we look at speeding up the build times with a remote builder, continued warning about accessories, implementing background jobs, setting up the infrastructure for background workers and diving more into the Kamal (MRSK) commands.

The Observer pattern (also known as publish/subscribe) provides a simple mechanism for one object to inform a set of interested third-party objects when its state changes.

In this episode, we look at adding Tailwind CSS to our Rails 7 application as well as applying a component library on top to add simplicity and consistency to our views.
