A huge upgrade for Python devs: uv just got even better | Issue #65


Hey there,

I've been using uv for all my Python projects lately. If you haven't made the switch yet from poetry, or pip/virtualenv/setuptools, this is a great time to try the tool.

In my latest video, I walk through the latest updates to uv, including a hands-on demo of how uv now handles project setup, dependency management, syncing, and more, all from one tool.

Uv now includes a fully integrated build backend, and as of version 0.8.0, it’s the default. That means no more extra config, and 10–30× faster builds.

What you’ll learn:

  • How to use uv init, install/remove dependencies, and run code inside your project environment
  • Why reproducibility is baked into uv by default
  • What a build backend actually is and why uv’s new one changes everything

Enjoy the video and I wish you a lovely weekend!

Cheers,

Arjan

P.S. I'm not associated with Astral (the company behind uv and ruff) in any way, I just like the tools they build.

Hey there, As you've probably discovered Python’s ecosystem is massive. Knowing which libraries to use will help you get your work done much faster. A couple of weeks ago, I asked you in a YouTube community post which libraries you're using that more people should know about. So in this week's video, I go over 14 modern Python libraries you probably haven’t used yet, but absolutely should. I cover tools for: Functional programming Modern pagination in APIs Slick console output and TUIs...

Hey everyone, There’s one design pattern that regularly shows up in Python code, for example in libraries like Pandas or Matplotlib. But most developers don’t even realize they’re using it. I’m talking about the Builder Pattern. This week’s video is all about this pattern. I cover: Why the Builder Pattern is so useful for building complex objects (like config files, HTML pages, or queries) When to use it and when not to A real Python example: building a small UI using a builder pattern How to...

Hey everyone, With AI agents and micro-SaaS tools popping up everywhere, it’s easy to think we’ll soon replace all traditional SaaS platforms by just vibe-coding our own. But that's an oversimplification. In my latest video, I break down: ✅ Why many SaaS platforms won’t disappear anytime soon ✅ Where AI-powered development is already transforming the landscape ✅ Which SaaS products are truly at risk, and which are stronger than ever Happy coding!
