Architecting Event-Driven Enterprise Transaction Systems At Million Scale Event-driven architectures offer a strategic path to real-time execution, resilience and operational transparency across modern enterprises.

Nice of Forbes to pitch EDA to "business leaders."

"The shift [..] to event-driven execution is a leadership decision about how an organization operates under scale, complexity and regulatory pressure."

If you're a business leader pondering that decision, I'm happy to help.

Relicensing with AI-assisted rewrite Exploring the chardet v7.0.0 controversy: Can an AI rewrite legally 'launder' a library from LGPL to MIT?

I'm captivated by this question: How can we protect open source copyright if AI can rewrite? What will it mean for open source software if we can't?

Trying Wispr Flow after friends raved about how good voice-to-text has become. But I have to stop recording to get it to type? Is continuous dictation possible? Or is there another LLM-based tool that does this?

Tomorrow is the last day of this year's OOP conference. Enjoying it very much so far. Many conversations around AI of course, but grounded and thoughtful ones, beyond the hype. And many familiar faces.

If you're here, join me tomorrow at 10am 👉 www.oop-konferenz.de/de/programm/...

The Kafka parallel consumer → github.com/confluentinc...
API makes more sense than standard Kafka clients. Parallel processing preserving per-key ordering, per-message acks, and automatic retries.
Could use modernization, but conceptually this looks nice.
Thoughts? Experiences?

Orchestration vs choreography for microservice workflows Orchestration and choreography can complement each other. There doesn’t have to be an exclusive choice between two opposing styles.

Really enjoyed “Orchestration vs Choreography for Microservice Workflows”. Short, clear, and nicely balanced.
Added it to the Awesome Event-Driven Architecture list 👍

BOB-Konferenz 2026: Vorträge zur funktionalen Programmierung und mehr Die Konferenz bringt Vorträge und Tutorials zu Themen jenseits des Mainstreams und KI, von denen sich viele mit funktionaler Programmierung beschäftigen.

Nice little 🇩🇪 article about @bobkonf.bsky.social

➡️ www.heise.de/news/BOB-Kon...

It's a small-ish conference with a community feel for people who want to explore (and push) the boundaries of software development. Great that it gets some media attention.

Beware the distributed monolith: Why Agentic AI needs Event-Driven Architecture to avoid a repeat of the microservices disaster - TNGlobal EDA for agentic AI systems is crucial because it promotes loose coupling, allowing agents to operate independently and communicate asynchronously. This approach prevents the same architectural pitfall...

On first sight, this article might seem like another example of slapping an AI sticker on a product to keep it interesting. But in this case, it makes sense. For agentic AI systems, event-driven architecture is still relevant.

Don’t try to solve hard problems: they’re telling you that your design is wrong. Instead, keep iterating the design until you only have easy problems.

OOP Konferenz | Patterns and Antipatterns for Event-Driven Architecture

The OOP in Munich was the first conference I ever attended as a junior dev. So I’m very excited to be back 25 years later, for OOP 2026, to speak about event-driven architecture.

👉 www.oop-konferenz.de/de/ueber-die...

On Friday the 13th 😨!
