Herzlich Willkommen zum WordPress Meetup Berlin! Auch im Jahr 2026 treffen wir uns weiterhin am letzten Mittwoch des Monats. Wir versuchen, abwechselnd Themen für Anwender\*innen und Developers behandeln. **Programm** 19:00 \| Einlass 19:15 \| Thema: Erstellen eigener Gutenberg\-Blocks Mit einem eigenen Gutenberg-Block macht man sich unabhängig von (möglicherweise kostenpflichtigen) Plugins, erweitert beliebig den Funktionsumfang des Editors und wird bei einer eigenen Umsetzung dank der Dokumentation auf developer.wordpress.org bestmöglich "an die Hand genommen". Matthias stellt euch in seinem Vortrag vor, was ihr dazu braucht und wie ihr die ersten Schritte gehen könnt. 20:15 \| "Flohmarkt" Jede\*r kann kurz ein Gesuch oder Angebot in wenigen Sätzen pitchen. Bitte achtet darauf, dass es nicht zu kommerziell wird. 20:30 \| Happiness Bar\, freies Networking & Gespräche\. Bei Fragen oder Problemen mit WordPress könnt ihr uns gerne ansprechen und wir helfen euch mit eurem Problem. Das nennen wir "Happiness Bar". **Teilnahme** Die Teilnahme ist kostenlos. Essen und Getränke können wir leider nicht bereitstellen. Es gibt einen Snack/Getränke-Automaten und einen Kaffee-Automaten in der Bibliothek. Ihr könnt euch auch gerne etwas mitbringen und im Meeting-Raum essen. In der Umgebung gibt es einige Bäckereien, Spätis und Imbisse. Wichtig ist nur, dass wir den Raum wieder sauber hinterlassen. Falls ihr euch angemeldet habt und es doch nicht schaffen solltet, meldet euch bitte ab, damit wir einen Überblick über die Teilnehmerzahl behalten. **Barrierefreiheit** Die Location ist barrierefrei für Rollstühle. Falls ihr Unterstützung bei der Teilnahme oder Anforderungen an die Barrierefreiheit habt, schreibt uns gerne eine Nachricht. **Code of Conduct** Als WordPress Meetup verpflichten wir uns den Code of Conduct (sprich: unsere "Verhaltensregeln") einzuhalten:[ https://wpmeetup-berlin.de/regeln/](https://wpmeetup-berlin.de/regeln/) **Weitere Details und Infos** WPMeetup-Berlin Website: [https://wpmeetup-berlin.de/](https://wpmeetup-berlin.de/) Facebook-Gruppe "WordPress Berlin Brandenburg": [https://www.facebook.com/groups/331013360390412/](https://www.facebook.com/groups/331013360390412/) Twitter Account @wp_berlin: [https://twitter.com/wp_berlin](https://twitter.com/wp_berlin) #WPBerlin **Location & Raumsponsor** Ein großer Dank geht an die Bezirksbibliothek Pablo Neruda, dass sie uns den Raum zur Verfügung stellen.

However, many of our attendees are able to understand English well enough to respond to your questions. Which means: if you understand but don't necessarily speak German, that should be perfectly fine.

**In Association With the Berlin Portrait Academy and PAKD Gallery / PAKD Art Lab** * **www.berlinportraitacademy.com** * **www.pakd-gallery.com/artlab** * **Cost: 15 Euros** A regular opportunity to study the nude or portrait from life for 3 hours, every single week! We have one long pose - you can choose whether to draw several studies from different angles around the room, or take your time to do a single sustained drawing or painting in full detail. The pose is held for 20 minute intervals with five minute breaks in-between so the model to rest and stretch, and so artists can move between seats if they choose. We provide some materials such as paper, pencils & pastels for free. Canvases, brushes and acrylic paint can be purchased at the event. We hope to see you there very soon!

**Weiter geht es mit dem Erfolgsnetzwerk** Wie angekündigt, geht es im 14-tägigen Rhythmus weiter. **Ablauf:** ***Bist du zum ersten Mal dabei?*** Dann sind wir gespannt, in der ersten Runde von deinem Projekt oder Vorhaben sowie deinem Hintergrund zu erfahren. Auch mögliche Hindernisse dürfen genannt werden. ***Teilnehmende, die schon einmal dabei waren,*** berichten von ihren Erfolgen und auch den Schwierigkeiten, die sie seit unserer letzten Zusammenkunft erlebt haben. Im Anschluss sprechen wir in der Gruppe über jedes einzelne Projekt, stellen Fragen und geben Feedback. ***Die dritte Runde gilt dem nächsten Schritt:*** Ihr überlegt euch konkret, was ihr bis zum nächsten Treffen erledigen wollt, um eurem Ziel ein Stückchen näher zu kommen. Das Erfolgsnetzwerk ist ein offenes Format für alle, die vor einem beruflichen oder privaten Projekt stehen und durch Austausch und Feedback ihre nächsten Schritte klarer sehen und umsetzen wollen. Ich freue mich darauf, euch beim nächsten Treffen zu begrüßen. Tickets gibt es hier: https://www.eventbrite.de/e/1989655053826

The longest day of the year is comming and let's another Kotlin meetup. This time we geather at N26! **⚠️⚠️⚠️ Due to a venue policy please submit the following form for additional details. Without it, you won't be allowed inside the venue:** https://forms.gle/XjqVXkD3FARCM6jA8 **Line-Up:** 👉 **TestBalloon: Kotlin testing is easier (and more fun) than you think** *by Oliver Okrongli* You want an easier way to write tests? Parameterize tests in plain Kotlin? Reuse a series of tests? Easily extend own your test setup? Have first-class support on all platforms? All without struggling with a huge framework API? TestBalloon is a new test framework that brings the power of Kotlin to your test setup. With a small-surface API, a hierarchical test structure and an extensible DSL, TestBalloon makes Kotlin testing easy, even at scale. Oliver, the author of TestBalloon, will show testing patterns and strategies and lots of practical examples, ranging from simple unit tests with less boilerplate to advanced testing with coroutines and generated data. This talk is based on insights first presented at KotlinConf 2026 in Munich. At the end of this talk, you’ll be able to firmly the answer the question: "How can I master Kotlin testing with ease, and make my team release with joy and confidence, every time?" 👉 **One Topic to Rule 'Em All** *by Yonatan Karp-Rudin* Kafka delivered every event exactly once, in order, and lost nothing. So what broke? This talk follows that question into the gap most event-driven systems leave open: what actually guarantees the order your domain depends on, and what quietly doesn't. We start from a real log line, find the crack in an architecture that looks clean and ships fast, and rule out the fix everyone reaches for first. The cure turns out to be one sentence of domain thinking plus one line of config, though the Schema Registry will fight you on the way there. A live demo runs the bug and the fix back to back: same load, same hero, one change. If you build with Kafka, you have probably shipped a version of this bug. You will leave able to spot it and fix it before it pages someone. 👉 **TBD** **Speaker Bios:** 🗣 Oliver Okrongli Oliver has been shaping and creating software from backend to frontends. He is the author of TestBalloon, a next-generation Kotlin test framework. Before, he has helped to maintain Kotest, and contributed to several libraries of the Kotlin ecosystem as well as the Kotlin compiler. Can be found on GitHub (OliverO2) and the kotlinlang Slack (Oliver O). When not developing, he is most probably in deep talks, dancing, snowboarding or F18 catamaran sailing whenever he gets a chance. 🗣 Yonatan Karp-Rudin Yonatan Karp-Rudin is a Staff Engineer at Billie, building event-driven systems in Kotlin and Spring Boot. Off the clock, he plays with AI agents and builds random tooling, trying to hand off as much of his own workflow to a machine as he can. The rest of the time he's brewing mead or deep in a video game. **🗣 TBD**

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
