Sneaky Code Bites Back I was adding SQLite support to Pongo when I realised that I'm talking to myself, and what I heard was insane. I was trying to understand and recap what I just built, an extremely clever and sneaky sol...

Just use SQL they say... Or how accidental complexity piles on “Just use SQL”, they say. “No need for ORMs”, they add. And they may be right, but… Let's look on how this can lead to accidental complexity piling on, derailing our initially simple problem.

How does "wrongly weighted just" look like? Check in my latest #ArchitectureWeekly edition:

My thoughts on Vertical Slices, CQRS, Semantic Diffusion and other fancy words Vertical Slices in software architecture are pictured right now as the best thing since sliced bread. I won’t try to hide that, like it. I've written about CQRS and Vertical Slices over the years - ho...

I still get questions about Vertical Slices Architecture (VSA).

After a recent discussions, in recent #ArchitectureWeekly, I want to share some additional thoughts on how I see Vertical Slices Architecture, how it relates to CQRS, what different slicing strategies are, and tradeoffs.

Predictable Identifiers: Enabling True Module Autonomy in Distributed Systems What if we could enable modules to communicate without knowing about each other's existence? What if a payment module could process requests from any source without being programmed to handle specific...

What if a payment module could process requests from any source without being programmed to handle specific scenarios?

I've explored in the latest #ArchitectureWeekly how predictable identifiers, specifically Uniform Resource Names (URNs), provide an elegant solution to this challenge.

The Underestimated Power of Hot Spots and Notes in EventStorming While teams naturally focus on mapping out those orange event sticky notes (the backbone of any EventStorming session), they often underestimate the power of two critical elements: Hot Spots and Notes...

Hot Spots and Notes might not get as much attention as domain events, but in my experience, they often separate a productive modelling session from a frustrating stalemate.

How does Kafka know what was the last message it processed? Deep dive into Offset Tracking Today we got back to our Kafka internals series. We discussed how it keeps track of processed messages. This may seem like a detail, but understanding it can be critical for smooth message processing....

Why does it do it this way? Wouldn't be simpler to just store in database the latest position?

That and more I discussed in the latest #ArchitectureWeekly.

As always, we take a specific tool and try to extend it to the wide architecture level.

I reshaped the #ArchitectureWeekly format last year, hoping to make it sustainable. I’m still not fully there yet, but that brought me closer. And enough to continue trying.

Thanks!

Last month I’ve made the Black Friday „offer”. And results surprised me. I gave 30 days trial for free to #ArchitectureWeekly.

Anyone could subscribe, read all articles, watch all videos (over 30h) and decide whether to stay.

I think that it’s fair for old subscribers and good option for new.

So yes, being an architect is also about talking.

Some may even say that it’s only about talking

This week, a surprising thing happened to me. In #ArchitectureWeekly, I try to share my perspective experience every week, but I don't like acting as an expert. That's why I am inviting special guests who know specific areas much better than I do. Sometimes, we do webinars, sometimes interviews.
