In my time as a developer, I have noticed that one of the most common ways my coworkers spend time coding outside of work is by developing little code snippets or apps that solve problems in their everyday lives. From household budgeting, to managing workouts on rowing machines, to generating a Taco Bell order, these projects allow devs to explore different coding styles and learn new technologies.

For a long time, most of my side projects have been for the sole purpose of learning a new technology. When I wanted to start building mobile apps with React Native, I wrote a small to-do app that, once finished, I abandoned. The same thing happened when I wanted to try to use PostgreSQL's listen and notify feature to build a live updating chat app. So, when I was thinking about a new side project, I decided it was time to work on something that could be long lived and help me with one of my favorite hobbies: crocheting.

A developer shares their experience building a Ruby class to generate crochet circle patterns. The article walks through analyzing the structure of crochet instructions, identifying mathematical patterns in stitch counts and increases, and implementing a pattern generator with RSpec tests. The solution handles special cases for the first two rows and uses different logic for odd versus even rows, ultimately creating a working generator that outputs properly formatted crochet instructions based on row count.
