PostgreSQL, MySQL, and MongoDB are Boring | Issue #20


Hi there,

Are you stuck choosing between the usual database options like PostgreSQL, MySQL, or MongoDB? It’s time to expand your toolkit! 🚀

In this week’s video, I’ll cover some of the most specialized databases out there! These aren’t your average databases; they’re optimized for specific tasks that can supercharge your software projects.

I’ll walk you through how to use these databases with Python, with hands-on examples and tips on how to integrate them into your tech stack.

But remember—every tool has its trade-offs. I’ll also share some key considerations to keep in mind when deciding which database is right for your project! 😉

Enjoy the video and happy coding!

Cheers,

Arjan

The Six Dumbest Ideas in Computer Security

Marcus J. Ranum recently wrote a thought-provoking blog post titled “The Six Dumbest Ideas in Computer Security.” 🛡️

In this article, Marcus critiques prevalent security practices, exposing flawed concepts like “Default Permit,” “Enumerating Badness,” and “Penetrate and Patch.” He argues that these approaches lead to ongoing vulnerabilities and inefficiencies in the field.

A big question was recently tackled on Discord: Is it really possible to write 100% pure Object-Oriented Programs (OOP) that are maintainable?

Rick got the conversation rolling after watching The Pain of OOP lecture, questioning whether modern frameworks force us into compromises—like using anemic objects or exposing too much state. Dale jumped in, suggesting that mixing functional and imperative styles could offer a better balance. Together, they unpacked OOP purity, immutability, and the challenges around method call history and mutable states.

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...

Hi there, You’ve probably heard that serverless is the easiest way to deploy code to the cloud. And on the surface, it is. With Google Cloud Functions, you can literally deploy a simple Python function like this: def hello(request): return "Hello from Cloud!" A few lines of code. No servers. No infrastructure. But... there are quite a few limitations: No FastAPI or async support One route per function requirements.txt only, no pyproject.toml Cold starts for large dependencies No custom...
