The Hexagonal Hangover
“It depends.” It’s the classic software architect’s answer… but what does it actually depend on? Patterns like Clean and Hexagonal Architecture are great tools, but they are often applied dogmatically. When we automatically wrap simple features in endless layers of abstraction and domain interfaces, we introduce unnecessary distance between related concepts. Those extra layers are intended to decouple, but they can sometimes just make our code harder to navigate, test, and maintain. In this talk, we’ll take a step back from “best practices” and look at the trade-offs behind architectural choices. Using clear Java code samples, we will explore the metrics that help guide these decisions: coupling, cohesion, and distance. Instead of looking for universally “clean” solutions, we’ll discuss how to evaluate what makes sense for your specific context.

About Ties van de Ven
Ties is a software engineer with a passion for concepts, software engineering fundamentals and helping others. He combines these passions by doing public speaking, volunteer work for organisations like Devoxx4kids and codingcoach and working as a Software Quality Expert at Alliander.

How to Survive and Thrive as a Dev (Team) in the Exponential Age of AI
The AI revolution isn’t coming — it’s already altering how we architect products, ship features, and run engineering teams.

During this talk, in his signature charismatic style, Sander Hoogendoorn, CTO at iBOOD.com and a seasoned developer with over four decades of coding experience, doesn’t get stuck in theory or hype, but confronts the pressing issues head-on. You’ll get a no-fluff, grounded view from iBOOD — what we’re already doing with AI, how we built it into our systems, and how it shapes the way we work.

We will walk through some concrete examples, for instance, using the Responses API, adopting the Model Context Protocol (MCP), embedding AI into our e-commerce workflows, and automating genuine parts of our stack. You’ll see where AI accelerates, and where it fails us.

We won’t shy away from the dark side either — vendor lock-in, breaking prompts, model opacity, shifting APIs, and how fast dependency can become fragility. These are real risks that shape architectural and organizational decisions we make daily.

To survive exponential speed, we retired many practices: no Scrum, no rigid ceremonies, no big upfront plans, no pull requests or code reviews. Instead, we embrace working in fluid autonomous microteams, continuous learning, experimentation, and radical adaptability.

Expect an honest, fast-paced, and experience-driven session — mixing architecture, culture, and practical insight — on what it truly takes for developers and teams to survive and thrive in the age of AI.

About Sander Hoogendoorn
Sander Hoogendoorn is an independent dad, avid traveler, and lifelong software developer. Coding since 1978, he still ships code every day — because once a developer, always a developer.

Currently CTO at iBOOD, he has led technology at several companies over the past decade and was once Capgemini's global agile thought leader. But don't expect corporate buzzwords: Sander is known for cutting through the fluff with a post-agile mindset and a healthy disregard for outdated best practices.

He helps teams and organizations break the rules that need breaking — replacing heavyweight processes with lightweight thinking, and agile dogma with actual flow. If something's slowing your team down, chances are he's already ranted about it in a keynote.

Onstage, he brings code, stories, and sharp insights on disruption, continuous delivery, microservices, monads (yes, really), software architecture, and the lost art of writing beautiful code. Fast-paced, thought-provoking, and never just theory.

Sander believes in small steps, critical thinking, and building stuff that works. No silver bullets. Just better software, made by better teams.

Nieuwsgierig naar de nieuwste lichting makers die klaarstaat om de creatieve industrie te veroveren?

Op woensdag 7 oktober transformeert de zaal van Focus Filmtheater opnieuw tot het podium voor het meest veelbelovende afgestudeerde talent uit de stad. Geen gortdroge verhalen, maar een avond vol energie, vlot tempo en toffe projecten van makers die reageren op de wereld om ons heen.
De vakjury boog zich over een indrukwekkende stapel portfolio’s van de Arnhemse academies. Laat je verrassen door de visies en ontwerpen van de geselecteerden van dit jaar:

Half Full. A Good Day to Open a Bottle of Wine.
Wine, at least the way we know it, is under pressure. Like any agricultural product, it responds directly to the climate: as temperatures rise and weather patterns become less predictable, some of the regions we associate with great wine today may no longer be viable by the end of this century.

Jelle Zegers
Product Design
Peter en de Magnetron. A good Day to Hum Along with Your Microwave
Sound is an essential part of how we interact with our surroundings. An object's characteristic sound influences our relationship with it. These characteristic, seemingly mundane sounds hold beauty. There is music in every object. And therefore, every object is an instrument.

Niels Nicola Pauls
Design Art Technology
Residual Protodermis
Sommige dingen waar we als kind van hielden verdwijnen niet; ze blijven liggen. In dozen, weggezet en half vergeten, bewaren ze de vorm van de uren die we er ooit in staken. Sommige daarvan raken gaandeweg ook gewild.

Niels Gräber
Design Art Technology
The Pigeon in the Machine
The Pigeon in the Machine is een serie sculpturen die de duif onderzoekt als symbool waar mens, natuur en technologie elkaar tegenkomen.

Jara Hermanns
Grafisch
Ex-libris
Ex-libris takes a deep dive into the choices behind twelve books that have been included in Best Dutch Book Design selections between 2020 and 2025.

Palina Hlavatskikh
Grafisch
Compromise
Compromise is a short film that follows a young woman who has just moved into a shared house. She performs small private rituals — counting rice, leaving offerings in quiet corners — hoping the space will accept her.

Stasha Pigkou
Fashion
The Great Escape
In The Great Escape zoekt Stasha Pigkou het verlangen naar verandering en de drang om aan jezelf te ontsnappen.

De vakjury van 2026
Wie bepaalt wie er op het podium staan? Een vierkoppige, multidisciplinaire vakjury heeft de afstudeerportfolio's nauwgezet gescand. Dit jaar gaven Mick Koopman (Mick Ontwerpt), Roos Meerman (Fillip Studios), Iris Ruisch (State of Fashion) en mediakunstenaar Mark IJzerman hun deskundige blik. Hun gezamenlijke selectie vormt een krachtige staalkaart van het nieuwste toptalent dat onze stad rijk is.

Entree
Via Focus: € 7,50 (gratis voor OPA members, maar meld je wel even aan)
