I was looking at @oskardudycz.bsky.social post on ordering & consistency and saw this part:

Balanced Coupling returns to @infoq.com🎙️
Back in early 2020, I presented the first version of the Balanced Coupling model at DDD Europe. The late Jan Stenberg — who is dearly missed — saw its potential and wrote about the talk on InfoQ.

Luca Mezzalira didn’t hold back — this one goes deep. The questions called for some serious introspection and took time to unpack.

What a great interview that was! I remember one of Sheen's questions totally derailed me—I couldn’t stop thinking, why on earth hadn’t I thought about that when writing the book???
Dive into Balancing Coupling in Software Design with @vladikk.bsky.social & @sheenbrisals.bsky.social to tackle complexity in modern software!
Takeaways:
Coupling is key to managing complexity.
Modular design reduces cognitive load.

Just finished @vladikk.bsky.social's "Balancing Coupling in Software Design". Great book. Describing "modules" as composable, hierarchical and fractal boundaries was the biggest insight for me, helped me build a better mental model of the design issues I'm trying to address.

Turns out it's more about WHERE to add functionality rather then HOW to add it.

Complexity rises, not from parts' number or size,
It's interactions among them, where troubles can rise.
While linear ones are simple and clear,
With complex interactions, failures loom near.

Are you avoiding conflict? Are you using techniques like “yes, and” that aims to create a sense of agreement, but you’re not really agreeing?
Strategy is conflict.
Therefore, you need to learn to be OK with it, I don’t ask you to be comfortable, but at least not avoid it.
