**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. ### Kom ook! **Kennisavond Meet Je Stad Utrecht** ‘Meten, weten en groeien; bomen voor een weerbare stad’ * Maandag 15 juni 2026, 20:00 tot 21:30 uur (inloop vanaf 19:30 uur) * Collegezaal bibliotheek Neude (Neude 11, 3512 AE Utrecht) * Toegang is gratis, [wel even hier aanmelden](https://forms.cloud.microsoft/e/mJLZKqHEMN?origin=lprLink) Meet je stad is onderdeel van Milieucentrum Utrecht en brengt via burgerwetenschap klimaatverandering in de stad in kaart, *[www.meetjestad.nl](http://www.meetjestad.nl/).*

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. **Program:** · 17:00 \- 17:30 \| Walk\-in · 17:30 \- 18:30 \| Diner · 18:30 – 19:30 \| Talk · 19:30 – 21:00 \| Borrel **🗓️ Date**: Monday 15 juni 2026 **⏰ Time**: 17:00 - 21:00 uur **📍 Location**: Nevelgaarde 20G, 3436 ZZ Nieuwegein ❗️**NOTE**: Our official name is PSG technauts.

**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.

I’m putting together a small hike trip weekend in Hoorneboegse heide in Hilversum, the idea is to come with a few people who want to step out of their routine, spend time in nature, and meet others in a relaxed way. This is not a tour or a structured retreat. The idea is simple step out of your comfort and everyday life to reconnect with nature and with each other. We will – explore the beautiful nature – share a few moments together – and keep things easy and natural There will be time together (walks and sunset). Group size will be small (around 2- 4 people), to keep it comfortable and personal. This Meetup is to connect people who are interested in real and human connection If this resonates, feel free to join and I’ll share more details 🙂

**Our Meetup is off to another hiking adventure! Mt Kilimanjaro, as the tallest mountain in Africa, is included in the 7 Summits of the world.** **It is a bucket-list item for all hard-core hikers and mountain lovers.** We did this trek with Meetup in the summer of 2024 and it was a true experience of a lifetime (see photos below) Let's get to some numbers. It is 5,895m/19,340ft BUT . . . our starting elevation for the trek is 3795m/12541ft As such elevation gain is 2100m/6799ft To compare Everest Base Camp trek, is about 2754m/9035ft elevation change. And Mt Whitney is about 1828m/6000ft elevation change. The key to being able to succeed in this endeavor lays in the route and the support system. We are taking the Lemosho Route via the Northern Circuit. The Northern Circuit route is the longest and newest of the seven established Kilimanjaro routes. It's one of the best routes because it has the best acclimatization profile. This results in one of the highest summit success rates. Add to that stunning views, and comparatively relaxed pace. It is also much less crowded than the other Kilimanjaro routes. As far as our support system: We will be accompanied by experienced guides, porters and cooks. They are certified, ensuring our safety and comfort. Porters will carry our gear. We will have a high ratio of guides to hikers. Our guides will go our pace and support each and everyone of us, regardless of fitness level and pace. In other words...you go your own speed and we all get there safe. More about our trek/trip. As with all our international trips, we picked the best season/time of year to go for weather and wildlife. Lemosho and Northern Circuit is a scenically spectacular and varied route. At the lower elevations it has an abundance of wildlife such as elephant, buffalo, eland and lion which come over to forage during dry season. **Each of our trips is personally crafted to offer the best places and best use of time.** *But I don't have the needed gear?!* You don't need much more than the standard trekker's equipment. We will provide you with a list of what is already included and what can be rented there. *Does this include food?* All meals on the trek potion are included and a cook travels with us! *What is lodging like?* We are sleeping in new and comfortable tents (carried during the day by porters) *I am new at this.* That's OK. We do plenty of prep Zooms before we depart. And in California we have a number of local outdoor day or weekend outings you can test out with us. *How dangerous is this? What if I get sick or hurt?* We will be walking on an established, well used trail the entire time. **Our trip INCLUDES emergency insurance.** We are also Certified Wilderness First Responders and our guides are members of (AMREF) Flying Doctor. **Plain and simple, safety is our primary goal.** *How much does this cost?* **Kilimanjaro Mountain Trek $3950 per person, double occupancy. Land only (airfare not included). Solo supplement $600** Trip Cost includes: \- 9 nights accommodation \- 3 meals everyday on the trek \- All Fees & Entrances and Taxes \- Camping equipment such as tents\, tables\, chairs\. \- Lead Guide\, Assistant Guides\, Porters and Cook *RSVP to this event shows your interest, but does not hold your space.* ***The only way to secure your spot for this trip is a $300 deposit:*** ***[CLICK HERE FOR SECURE DEPOSIT LINK](https://www.paypal.com/instantcommerce/checkout/8P9NUAVQM8UEN)*** *Deposit is refundable up to 90 days before the departure (less PayPal fees).* *IF you need an airfare quote,* [Click here to message Anna](https://secure.meetup.com/messages/?new_convo=true&member_id=131297062) For more information about this or any of our other international events, fill out this form: **[INTERNATIONAL MEETUPS INFO REQUEST](https://forms.gle/cQdqYw74gAYqphXX8)** To see pictures from our Kilimanjaro adventure in 2024 [CLICK HERE](https://photos.google.com/share/AF1QipPkfkUp6sEZVQ-xse1di_K19d1QVmSb5KOLeIjynRoWGv_XFLXI8wBfT61XxAHavg?key=U2tKajBuOGRiZkxBOUtTUG1GbUVRVmlDaERCeG5n) We do a monthly Q & A Zoom: Meet others attending, be social, or come and get any questions answered.
