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.

**Um was geht es dieses mal?** **Barrierefreiheit automatisiert testen - Anna Maier (codecentric)** "Barrierefreiheit – ein Produkt für alle nutzbar machen - ist ein komplexes Thema. Bei der Entwicklung barrierefreier Software müssen viele Anforderungen berücksichtigt werden. Ein großes Problem ist, dass das Testen ein weitgehend ein manueller Prozess ist. Das kollidiert mit den schnellen Veröffentlichungszyklen moderner Software. Wie können wir unser Tempo beibehalten und gleichzeitig sicherstellen, dass das Produkt zugänglich bleibt? In diesem Vortrag gebe ich euch das Handwerkszeug, um euch in Hinblick auf Barrierefreiheit besser abzusichern. Dabei lernen wir zunächst automatische Tools und ihre Möglichkeiten und Grenzen kennen. Danach schauen wir auf Strategien zum Schreiben eigener Tests mit gängigen Testframeworks. Abschließend schauen wir uns an, wie KI uns in dieser Hinsicht unterstützen kann" **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.

We’re heading out for a beautiful 20 km loop hike from Afferden through the gorgeous Nationaal Park De Maasduinen. This route takes us through a striking Limburg landscape of forest, sandy paths, open heathland, river dunes, and wide views. Along the way, we pass the ruins of Kasteel Bleijenbeek and climb an uitkijktoren for a panoramic view over the Maasduinen landscape. One of the special features of this hike is that we cross the Maas river twice by small ferry. These crossings give the route an extra sense of adventure and connect the Maasduinen landscape with the village side of the river. After one of the crossings, we continue to the village of Vierlingsbeek, where we’ll take our longer break for a drink. After the break, we make our way back toward Afferden, completing a varied loop through forest, heathland, castle history, river scenery, ferry crossings, and quiet Limburg countryside. A hike with forest energy, open heathland, castle ruins, a lookout tower, two Maas river crossings, and a relaxed village drink stop. **📍When and where to meet?** We’ll meet at 11h15 at Busstop "Afferden, Veer naar Sambeek" https://maps.app.goo.gl/kcg4hBvRsHoUjBSa6 ⏰ **We start walking a few minutes after meeting up** We don’t wait for latecomers, as we have a long route ahead and want to enjoy the full day properly. **🚗 Coming by car?** Please check your parking options beforehand so you arrive on time. **⏸️ Planned Breaks** After **4 km:** break at watchtower (5 min) After **7 km:** Having a lunchbreak at ruins of Castle Bleijenbeek (25 min) After **13 km:** Ferry over the Maas After **14 km:** Drinks at bar in Vierlingsbeek (50 min) After **20 km:** Ferry back over the Maas (bring small change to pay the ferry) I still need to confirm or make a reservation at the bar. **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Welcome, readers! Our June read is ***Endurance: Shackleton's Incredible*** ***Voyage*** **by Alfred Lansing.** A work of nonfiction, and one of the most astonishing survival stories in history, we follow Sir Ernest Shackleton and his crew after their ship is crushed by Antarctic ice. Stranded in one of the harshest environments on Earth, the men endure months of isolation, freezing temperatures, and near starvation—yet refuse to give up hope. Lansing brings their ordeal to life through vivid detail and firsthand accounts, capturing both the brutality of nature and the resilience of the human spirit. At its core, the story is a powerful testament to leadership, perseverance, and the unbreakable will to survive against impossible odds. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **all** **drinks must be purchased at the bar.** Happy reading! 📖
