10 Git Features You Probably Didn’t Know About (But Should!) | Issue #21
Published 9 months ago • 3 min read
Hi there,
Did you know Git has a ton of hidden features that can seriously level up your coding game?
In this week’s video, I explore 10 Git features most developers don't even know about! 😲 From the clever use of Git Notes to the lifesaver that is Git Worktree (ever wish you could work on two branches at once?), I’ve got some cool tips to share.
If you're looking for ways to make your Git workflow smoother and more efficient, you don't want to miss this one. Let’s "git" going! 💻💪 Enjoy the video and happy coding!
Cheers,
Arjan

Let’s make it an awesome event—see you there! 😉
Why I’m Switching to Polars
In his latest post, Ari Lamstein shares why he’s making the leap from Pandas to Polars for data manipulation.
He highlights Polars’ intuitive syntax and how it simplifies working with dataframes, much like the Tidyverse did for R users. While performance gains are a bonus, it’s the ease of use that sealed the deal.
If you’re looking to level up your data game with something both faster and simpler, this is a must-read. Check out the full blog here.
# Community
Plant_Boy, one of our community members, recently kicked off a great discussion on Discord about what really defines a Senior Engineer/Developer. Is it just a title, or are there concrete differences in responsibilities and expectations?

Hey everyone, I love it when I come up with a design that uses exactly the things I thought were a sign of bad design. In this week's video I show you how to build a clean Python SDK for a REST API. The idea was simple: create a reusable base model that handles all the CRUD operations so you can just write User.find() and user.save(), without duplicating logic all over your codebase. Sounds great, right? Well, after recording the video, I realized something: not all APIs will have all CRUD...
Hey everyone, Python’s flexibility is great, but if you're working on a larger project it becomes hard to make sure not everything depends on everything else. There is a way to avoid that trap, and that's by using abstractions. Unfortunately, I often see production code with way too much coupling that can be easily improved by relying on abstractions. This week’s video shows simple abstractions using Callable, ABC, and Protocol. You’ll learn how to: Reduce unnecessary imports Decouple your...
Hey everyone, I was reviewing some of the projects I’ve worked on over the past year, and I noticed something interesting: I almost never use Python’s @dataclass anymore. Not because it’s bad. In fact, dataclasses are still a great feature of the language. But as my projects have grown more complex, especially with tools like FastAPI, Pydantic, and SQLAlchemy, I’ve found that dataclasses just… don’t fit the way I design software anymore. In my latest video, I dive into this in detail. You’ll...
