If I were to recommend three articles published last week to read, here is what I would recommend:

1️⃣ What’s New in Ruby on Rails 8 by Damilola Olatunji

This article offers a concise summary of the key features coming to Rails 8. Damilola provides an excellent high-level overview, while also delivering detailed insights into each feature.

You might also want to check out the Hacker News discussion related to this article. It has a great vibe about Ruby on Rails 8.

2️⃣ How CDNs Work (Propshaft / Static Assets Pt. 2) by Jon Sully

In this article, Jon provides a visual and clear explanation of Propshaft's work when serving the assets files. This is a continuation of a previous article about How Propshaft Works: A Rails Asset-Pipeline (Visual) Breakdown, which is also a very good article with explanation and explanations of Ruby code samples.

3️⃣ B-trees and database indexes by Benjamin Dicken

While this article isn't about Ruby, it is an excellent and well-written resource for understanding B-trees and database indexes. It deep dives into details explaining how indexes work and includes animations that help you feel the concepts.
