ActiveJob Callbacks

#505 Apr 13, 2025 pro

Callbacks are typically something that I avoid or try to use only if they make sense. However, in background jobs, they have a different feel to them and can be very powerful while helping keep the code organized. In this episode, we'll explore three different callbacks in the background jobs.

Boolean vs Datetime

#504 Apr 6, 2025 free

In this episode, we look at refactoring an existing application where it uses a boolean to determine if a post is published or unpublished. However, this feature has its limitations, so we change the functionality to work off of a datetime column instead.

Vibe Coding

#503 Apr 1, 2025 free

Time to stop hiring $100k/year developers and hire an intern for $10k/year and pay $100/year for an AI Agent. The intern doesn't even need to understand the code it is generating and just help guide it to the solution. Sadly, this has to be said because people do not watch the content. This is satire.

Classification Models

#502 Mar 30, 2025 pro

Continuing from the previous episode, we look at removing the LLM in favor of a Classification Model. This will allow a more directed course of action for the Rails application to take based on the user input. We'll also look at fine tuning the model so that we are able to get better classifications of the user input.

Chat Agent

Confetti

#500 Mar 16, 2025 pro

In celebration of Episode #500, we'll be looking at adding confetti to our Rails application. While seemingly a bit silly, this can add a bit of flare to your application when used properly.

Embeddings

#499 Mar 9, 2025 pro

In this episode, we explore embeddings and how they improve search and recommendations by converting text into numerical vectors. We'll set up a Rails 8 app with PostgreSQL + PG Vector, generate embeddings, and perform similarity searches.

Conditional Queue

#498 Mar 2, 2025 free

In this episode we look at processing background jobs in a way that can conditionally send the work to be processed to different queues. This can be very powerful in situations where you need to process the job in different ways or send requests to different APIs.

Development Approach

#497 Feb 23, 2025 pro

Working with 3rd party integrations can be time consuming, complicated and we can take many different approaches when creating a proof of concept. In this episode, we're going to look at creating a development environment with Jupyter Notebooks so that we can iterate fast and remove a lot of the complexities of our application.

Frozen String Literal

#496 Feb 16, 2025 pro

In this episode, we're going to look at the magic comment frozen_literal_string and what it does. We're going to look at various behaviors and migration paths to prepare your application for future versions of Ruby.
