AI coding agents can inspect a Rails repository, edit several files, run tests, interpret failures, and revise their work.

When I optimize a slow Rails endpoint, I create a small profile_compare script for that specific workload.

A request that takes 900 ms tells us that something is slow, but not where the time went.

You know what an N+1 query is: one query to fetch a collection of users, then one more query per user to fetch their posts.

When people build an AI research product, the first architectural decision is often which agent framework to use.

Working on a legacy Rails codebase can be challenging.

Before Rails 8 we always used something like the devise gem for authentication.

As Rails developers, we often focus on writing clean, efficient Ruby code.

Rails Active Record is a powerful ORM that simplifies database operations, but complex queries can sometimes lead to performance issues.

The convenience and power of Active Record allows you to interact with your database in a more Ruby-like way, making it easier to write efficient and readable code.

In Ruby on Rails, A generator is a tool that helps create scaffolding (basic code structure).

When building applications in Ruby on Rails, We store data in Plain Old Ruby Object (called PORO) value objects.

Active Record strict loading is an awesome feature in Rails that can significantly improve your application’s performance by preventing N+1 queries.
