I'm in prison | Issue #52
Published 3 days ago • 2 min read
Hi there,
I’m emailing you from prison. 🚨
No, not like that.
The new ArjanCodes office is inside a 19th-century prison in Utrecht. And it’s actually… amazing. The cells are now offices, the vibe is creative, and it’s got just the right kind of gloominess for video production (because direct sunlight and camera lenses don’t mix).
In this week’s video, I take you on a little tour of the space and talk about what’s ahead for the channel. After a year of scaling down, I’m finding more balance—and bringing back more of the real coding content you’ve been asking for.
🛠️ Think design patterns, Python concepts, and refactoring code that’s on life support.
Happy coding and enjoy the tour!
Cheers,
Arjan

⚡️Hot Module Replacement in Python? Yes, Please.
Restarting your Python app after every little change? 😩 Been there.
Evan Doyle from Gauge has written a super practical guide on implementing Hot Module Replacement (HMR) for Python projects. Think instant reloads, preserved state, and a massive boost to your development speed.
Instead of restarting your entire app, this method only reloads the modules that actually changed. It’s a clean, dependency-aware approach—and it works really well.
Can you write Python code that’s clever, minimalist, and still surprisingly functional? Absolutely.
In Elliptical Python Programming, Susam Pal takes a playful detour through Python’s more obscure corners—highlighting how even the most roundabout expressions can lead to beautifully unexpected results.
It’s a fun, thoughtful read that blends technical insight with a touch of code artistry. If you enjoy bending the rules (without breaking them), you’ll love this. 👉 Check out the full article here.

Recently in our #📚resources channel, JamesParrott shared an interesting video on how to securely store secrets for cloud software—no more .env files in your Docker images!
🔐 The video covers a clever method for handling secrets and even answers a long-standing dev dilemma: “How do I generate MFA codes if my phone breaks?”
Head to the thread in our Discord and check it out—lots of great insights and a helpful video recommendation await.

Hi there, We all know type hints can catch bugs before runtime. 🐛 But what if I told you they’re also one of your best tools for designing better software? In this week’s video, I show how type hints can lead to smarter choices about inputs, outputs, and even class structure — all without adding complexity. It’s the kind of thinking that leads to better architecture and fewer “why did I do this?” moments later on. 😌 And yes, I also drop a few tips you’ve probably never heard about inputs and...
Hi there, If you’ve ever used Python decorators, you know they look like a clean way to add functionality. But have you ever struggled to debug a decorated function? Or wondered why your type hints suddenly break? Or spent way too much time figuring out why your decorators aren’t working as expected? 🫠 🚨 Decorators introduce hidden complexity that can turn your code into a nightmare. And honestly? I think they’re overused. In this week’s video, I explain: Why decorators break type safety and...
Hi there, Ever looked at your old code and felt secondhand embarrassment? Yeah, me too. Keeping your code simple and maintainable is an art. In today’s video, I break down 10 essential tips that will help you write cleaner, more efficient Python code. 🚀 Some key takeaways: 🛑 Stop overengineering—simple solutions are often the best. ✂️ Cut the copy-paste habit—DRY code is maintainable code. 🧹 Refactor before your code turns into a horror movie.
