Kennisavond - Bomen in de stad en hun invloed op het microklimaat
**Hoe kunnen we onze steden koel genoeg houden nu ze door klimaatverandering in de zomer steeds heter worden? Met deze vraag als uitgangspunt organiseert Meet je stad Utrecht op maandag 15 juni een kennisavond in bibliotheek Neude over de rol van bomen bij het beperken van stedelijke hittestress.**
### De rol van bomen in de klimaatbestendige stad
Onderzoeker dr. Daniela Maiullari van de TU Delft vertelt maandagavond 15 juni over de groeiende uitdaging van hittestress en legt uit hoe bomen in steden echt een verschil kunnen maken. Aan de hand van voorbeelden uit onderzoeksprojecten van de TU Delft behandelt ze monitoringtechnieken om stedelijke hitte te beoordelen en bespreekt ze de verkoelende werking van bomen.
Ook presenteert dr. Maiullari de nieuwste inzichten over hoe bomen functioneren in stedelijke omgevingen en hoe groene planningsstrategieën – zoals de 3-30-300-regel – kunnen helpen bij het verminderen van stedelijke hitte. De 3-30-300-regel gaat ervan uit dat elke bewoner vanuit zijn woning minstens drie volgroeide bomen kan zien, in een buurt woont met 30 procent boomkroonbedekking en binnen 300 meter toegang heeft tot een groene buitenruimte van een halve tot een hele hectare.
*Dr. Daniela Maiullari is universitair docent aan de TU Delft. In haar onderzoek richt zij zich op stedelijke micro-klimaten, energietransitie-strategieën en klimaatadaptief ontwerp, met een sterke nadruk op datagedreven methoden. Zij geeft haar presentatie in het Engels.*
### Uitbreiding onderzoek
Na de presentatie van Daniela Maiullari willen wij met de deelnemers in gesprek om te kijken of er behoefte is aan een aanvulling van het huidige burgerwetenschappelijke onderzoek naar een gezonde en klimaatbestendige stad. Tot nu toe verzamelt Meet je stad gegevens over temperatuur, luchtvochtigheid en fijnstofconcentraties. Zijn er andere gegevens die jullie belangrijk vinden? Over welke onderwerpen rond het klimaat in de stad maken mensen zich zorgen? En zijn er specifieke plekken waar mensen meetgegevens willen verzamelen? Aan de hand van de verzamelde onderwerpen gaan wij kijken hoe het onderzoek kan worden uitgebreid.

SonarQube: Ensuring Code Quality & Security
Clean code is essential for maintaining speed and reliability in software development. Poorly structured or inconsistent code introduces friction, slows teams down, and increases the risk of defects. This is where SonarQube comes in.
SonarQube is a platform that helps teams continuously inspect and improve code quality. It supports a wide range of languages, including Java, Python, and JavaScript, as well as Infrastructure-as-Code technologies like Terraform and Kubernetes Helm charts.
By analyzing your code, SonarQube identifies issues and presents them in a clear dashboard. These issues are categorized as Bugs, Vulnerabilities, and Code Smells, each with a defined severity. Behind the scenes, these findings are based on rules organized into language-specific quality profiles, which can be customized to match your organization’s standards.
SonarQube can also be integrated into your CI/CD pipeline, enforcing quality through Quality Gates.
In this talk, I’ll introduce the core concepts and explore advanced features that can help you get even more value from the platform.

Swimming lessons for adults | Beginners
If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer.
Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives.
Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

Das Ende der Code-Ära: Domain Modeling & Harness Engineering
**Um was geht es dieses mal?**
**Das Ende der Code-Ära: Warum Domain Modeling & Harness Engineering die wichtigsten Skills 2026 sind. - Benjamin Font Pera (codecentric)**
"Die Ära, in der Softwareentwicklung primär durch das Beherrschen von Programmiersprachen und Frameworks definiert wurde, ist vorbei. Wer 2026 noch versucht, über reine Syntax-Kenntnisse Wertschöpfung zu generieren, hat gegen agentische KI-Systeme bereits verloren. Die eigentliche Herausforderung hat sich nach links verschoben: in die präzise Definition von Problemen und die Konstruktion von Leitplanken.
In diesem Talk räume ich mit dem Mythos auf, dass KI uns das Denken abnimmt. Im Gegenteil: Die Verantwortung steigt. Ich stelle das Konzept des Harness Engineering vor – die Kunst, fachliche Anforderungen so in Test- und Evaluationsgerüste zu gießen, dass KI-Systeme darin verlässlich operieren können.
Als Agentic Coding Engineer und AI Coach zeige ich auf, warum Fachlichkeit zur wichtigsten technischen Fähigkeit wird. Wenn die KI Code generiert oder “halluziniert”, ist das tiefe Verständnis der Domäne das einzige verlässliche Werkzeug zur Qualitätssicherung.
Die Kernbotschaften:
Problem-Definition als Hard-Skill: Warum die Fähigkeit, komplexe Fachlichkeit präzise einzufangen, das neue „Clean Code” ist.
Harness Engineering statt Code-Fixing: Wie wir die Kontrolle behalten, indem wir das „Harnisch” (Evals & Guardrails) bauen, statt Zeile für Zeile zu reviewen.
Shift Left zur Domäne: Warum Entwickler:innen 2026 mehr wie System-Architekten und Domänen-Experten denken müssen, um relevant zu bleiben.
Lessons Learned vom AI Coach: Warum die größten Hürden dieser Transformation nicht technischer Natur sind, sondern im Mindset der „Lösungs-Produzenten” liegen.
Dieser Vortrag ist ein Weckruf für alle, die Softwareentwicklung noch als Handwerk am Code verstehen – und ein Leitfaden für diejenigen, die bereit sind, die nächste Ebene der Abstraktion zu besetzen."
**Hybrides Setup!**
Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben.
Den Live-Stream findet ihr auf dem [YouTube-Channel](https://www.youtube.com/@codecentricAG) der codecentric AG.
**Wichtig - Absage bitte rechtzeitig:**
Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis!
**Anreise:**
Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß.
Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

Immersieve ervaringen: van verhaal tot beleving
*Please note: this meetup will be held in English.*
In this first meet up, you will be shown a set of immersive artistic and design research experiments.
Project Thuis conducts two years of artistic and design research into immersive experiences that place the body at the centre. The central question is: "How can immersive experiences in (semi-)public spaces contribute to a sense of connection, belonging, and 'feeling at home'?
To explore this, a multidisciplinary consortium consisting of [Fillip Studios,](https://www.fillipstudios.com/) [affect lab,](https://www.affectlab.org/) [Introdans,](https://introdans.nl/) [Utrecht University,](https://www.uu.nl/staff/SPonzanesi) and the [Amsterdam University of Applied Sciences,](https://civicinteractiondesign.com/) has embarked on a creative journey together.
Within the context of Project Thuis, this meetup will focus on artistic and design research forms applicable across various disciplines.
**Programme:**
16:00 - 16:15: Opening
16:15 - 17:15: Interactive session
17:15 - 17:30: The role of the maker in the future of immersive experiences
17:30 - 18:00: Networking and drinks (including presence of [CIIIC](https://us2.mailchimp.com/mctx/clicks?url=https%3A%2F%2Fwww.ciiic.nl%2F&xid=f4ced03a90&uid=2313462&iid=e62065ab18&pool=cts&v=2&c=1780312609&h=0b99fb0b79b5fe3d2625a4891bea9d8bc6ef045db3b8ee6ffe56d6cfc6e501c4))
Within the context of Project Thuis, this meetup will focus on experiments that you, as a maker, can use to conduct artistic and design research across various disciplines.
*[This event marks the first in a series for Project Thuis (Home). Ontwerp Platform Arnhem has been invited to organise the meetups. We strongly endorse the importance of initiatives like this, and are highly committed to connecting designers with these themes and consortia](https://www.ciiic.nl/)***[.](https://www.ciiic.nl/)**
