Be CAREFUL With Removing Code Duplication | Issue #24

Published 27 days ago • 2 min read

Hi there,

​

Ever struggled with code duplication? It can creep into your projects in ways you’d never expect. 🚨
​

In this week’s video, I’ll show you some tricky examples of duplicated code that might not be obvious at first glance. 👀 I also explain why simply following the DRY principle can sometimes make things worse.
​

I’ll walk you through a refactor of one such case and even show you an example where not removing duplication is the better choice!
​

Watch until the end of the video for some BONUS tips on how to avoid writing duplicate code without turning your project into a mess of confusing abstractions.
​
Enjoy the video and happy coding!

​

Cheers,

Arjan

Free Threaded Python With Asyncio

Free-threaded Python removes the Global Interpreter Lock (GIL), making true multithreading possible! 🧵

​Jamie Chang’s recent article digs into how this update lets you run both CPU-bound and IO-bound tasks using AsyncIO. He gives a practical example with asyncio.to_thread() and shows off some nice performance gains on a MacBook M3.

Still scratching your head about the GIL? Check out my video for a full breakdown, or dive into my thoughts on Python 3.13 right here.

A community member recently shared a video on Primitive Obsession—an OOP code smell—sparking an interesting debate around the use of value objects to resolve it.

Some find the approach helpful, while others see it as a polarizing topic, with lots of strong opinions on both sides.
