So, today I messed around with something called “c42”. I had heard about it before, kinda knew it was related to organizing things, but I never really dug into it. Time to change that!

Getting Started
First, I needed to figure out what the heck “c42” actually meant. I did some searching and found that it is something for drawing.
I found a nice drawing board that I will use.
The Nitty-Gritty
Okay, the basic idea is this:
- Containers: The biggest boxes. Think of these like major parts of your system, for instance.
- Components: Smaller boxes inside the Containers. So, if your Container is a “web application,” a Component might be a “user authentication service.”
The whole point is to keep things simple. No super-detailed diagrams, just enough to understand the big picture.
Putting It Into Practice
I started by drawing a big box. I used the tool I found for this.

Then I draw one more box that is inside the big box. That is all for my practice today.
I played around with moving the boxes and all of that, and it all worked out.
My Thoughts
Honestly, this seems pretty useful. I could see myself using this to explain stuff to other people, or even just to organize my own thoughts before diving into a big project. It’s like a visual outline, and who doesn’t love a good outline?
I’m definitely going to keep this “c42” thing in my toolbox. It’s simple, but effective. And sometimes, that’s exactly what you need.
