Do you teach Python? Then check out course-setup
TL;DR: If you teach Python, then you should check out course-setup (https://pypi.org/project/course-setup/) at PyPI! I’ve been teaching Python and Pandas for many years. And while I started my teaching career like many other instructors, with slides, I quickly discovered that it was better for my students — and for me! — to replace them with […]

Decorator vs Proxy Pattern in C#: Key Differences Explained
Decorator vs Proxy Pattern in C#: Key Differences Explained
If you've ever looked at the source code for a decorator and a proxy side by side, you might have done a double-take. Both patterns wrap an object. Both implement the same interface as the object they wrap. Both forward calls to that inner object. So why do we treat them as different patterns at all? The decorator vs proxy pattern C# comparison is one of the most common sources of confusion among developers learning structural design pa...

What’s Arturo?
Best I understand, Arturo is a stack-based programming language. It’s primarily maintained by Yanis Zafirópulos. They published a vision of the language in 2020. Here’s the stated goal from that post:
to make something that I myself will use as an easier do-it-all scripting language, you know… automation scripts, templating, latex g...

Little web app to pick a random programming language
I wrote a web app to choose a random programming language.
It’s very simple; I hestitate to even call it an “app”! The interesting part was scraping all the languages on Rosetta Code, and even that wasn’t very interesting. But I hope you like it!
I learned about a language called Arturo this way, and wrote a short story about that experience....
