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.

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.

Using Git Hooks is a great way to automatically execute scripts for parts of your development process that you may otherwise forget to run. In this episode, we look at creating a maintainable way to install and manage git hooks so that they can be used in your project and shared to other team members.

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.
