Exploring Polymorphism in C: Lessons from Linux and FFmpeg's Code Design (2019) (leandromoreira.com)
Learn how Linux/FFmpeg C partial codebase is organized to be extensible and act as if it were meant to have “polymorphism”. Specifically, we’re going to briefly explore how Linux concept of everything is a file works at the source code level as well as how FFmpeg can add support fast and easy for new formats and codecs.

Getter-Setter Pattern Considered Harmful (wolfgang-ziegler.com)
Many developers (like myself) who started their careers with OOP (Java, C#, ...) during the last decades will look at this code and find nothing wrong about it at first sight.

Standard patterns in choice-based games (2015) (wordpress.com)
When I was analysing the structures of CYOA works a few years back, I began to recognise some strong recurring design patterns.

How to Write Complex Software (grantslatton.com)
Suppose you are implementing some complex piece of software — a database, a word processor, a filesystem, a web browser, whatever. How do you get started? How do you actually organize the code?

Enum of Arrays (tigerbeetle.com)
A popular data-oriented design pattern is a Struct of Arrays. Is an Array of Enums also useful? Yes! But let’s do a refresher on struct of arrays (SoA) first:

Visitor Pattern Considered Pointless – Use Pattern Switches Instead (nipafx.dev)
In modern Java, the visitor pattern is no longer needed. Using sealed types and switches with pattern matching achieves the same goals with less code and less complexity.

A C++ Mixin System (jennyjams.net)
I've had this idea in the back of my head for a while of pervasively using mixins to add code and logic for more high level concepts, although this gets somewhat close to Rust style traits (and C++ concepts). This has existed in the back of my head for a long time as a way to model a framework or standard library implementaiton while also providing it for user types.

Killing the Command message: should we use Events or Documents? (2007) (microsoft.com)
If we want to decouple a SOA system, we must get away from the notion of the remote procedure call. In other words, our services need to have as few "command" messages as we can get away with. This is a design philosophy but it is easier said than done.

"Design It Twice"? (16elt.com)
Designing software is tough. I think we can all agree on that. No matter how much experience you have, your first idea about how to structure a module or system is usually not the best one. I had to learn this lesson the hard way, and I really wish I knew about the “design it twice” concept earlier in my career.

Design Patterns Are Temporary, Language Features Are Forever (ptrtojoel.dev)
Design patterns are these cool things that make you go 'hell yeah' because they make a certain problem easier to deal with. Whether it's applicable to all languages, or due to a language constraint, they're pretty nice. Of course, some people go crazy with them rather than doing the simple thing that works. Other times, you'll naturally do a design pattern without even knowing about it.
