Am 26./27.11. gebe ich in Hamburg mein Training zu Event-Driven Architecture, bewusst vor Ort: zwei Tage raus aus dem Projektalltag und Zeit für die Grundlagen. Outbox, Idempotenz, Fehlerbehandlung, Prozesse über viele Services. 🧵

EDA gets recommended for microservices. Then a real business process turns up, and inventory, payment and shipping all have to move together. The usual reach is a workflow engine or the Saga pattern: one coordinator sends commands and waits for replies.

New talk: the Kafka ecosystem in 2026. Drop-in alternatives speaking the Kafka protocol (Redpanda, WarpStream, AutoMQ, Bufstream), what diskless architectures actually change, smarter clients, proxies and gateways, plus KIP-932 and KIP-1150. Kafka is a protocol now, not just a broker. #kafka #eda

It's wrap (for me, anyway) for the @wearedevelopers.bsky.social European Congress this year. The congress is not like other conferences I go to. It's bigger, noisier. Great crowd (massive amount of people, > 10000 or so), young, international, energetic.

I‘ll be at the WeAreDevelopers World Congress in Berlin next week. Happy to discuss building and evolving engineering organizations, strategic technology leadership, or event-driven architecture. If you’re also there and want to meet up, DM me. #eda #eventdrivenarchitecture #ddd #teamtopologies
The wearedevelopers conference is held from July 8 - 10 in Berlin, Germany

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/... #oop

Next up: Ronna Steinberg. Just 2 minutes in, my favorite quote of the conference, for sure: „It‘s not schön if it‘s not fun.“ She made it rhyme somehow.

My KanDDDinsky talk this year: less fundamental than my usual talks. More: what works well, and what doesn’t. Patterns, lessons, and maybe a few true stories. The line-up is amazing, and I’m humbled to be part of it. Hope to see you there! 👉 kandddinsky.de #ddd #EDA #conference #Berlin #kandddinsky

Coding with AI feels like teaching. You still need to learn before you can teach. Deep understanding of the domain and software quality still matters. But not everyone who enjoys coding will enjoy instructing a machine. It’s a different kind of creativity. #AIProgramming #CodingWithAI #DevThoughts
Altered quote from Alberto Brandolini, now saying "Software Development with AI is a teaching experience".

Always wanted this to be interactive so I could solve the cube in 2D. Everyone’s using AI code assistants now, so I had Claude build a first version. It’s rough - no tests yet - but already fun to play with (for me, anyway): www.huehnken.de/games/circle... #AIgenerated #LLM #puzzlegame #claude

I said I expected to be inspired, and Fast Flow Conf did not disappoint. Great talks all around, kudos to the speakers. And the closing keynote hitting a point for me as well, moving beyond "enabling team" for architecture. Great day. Also fantastic venue and organization! #ffc25 #fastflowconf

In "Foundations of Scalable Systems", Ian Gorton writes, among other things, about relational databases and how it's not uncommon to apply denormalization. Or well, he meant to, but on page 196 they printed something else.. which I'm sorry to hear 😀 #softwarearchitecture #bookclub #mademechuckle

I miss the old Twitter, I really do. So it took me longer than it probably should to disassociate from what it has turned into. Still hoping that some other site will become what Twitter used to be. Maybe this one?

Four images of olympic shooters that have gone viral, comparing them to programming languages. Heavily equipped, looking very complicated: Scala. Looking modern and high-techy: Rust. Just wearing a t-shirt, keeping it simple: Go Lang. Look in a mirror and shoot backwards: JavaScript.
