Seminars

**One week later than usual! We'll be at the small Seminarraum instead of the mainhall.** **BitDevs Bitcoin Socratic Seminar Berlin @ c-base Raumstation** Join us for our monthly interactive **[Bitcoin Socratic Seminar](https://bitdevs.berlin)** in Berlin! We’ll start with pizza and beer (sponsored by [Ordimint.com](https://ordimint.com)), followed by deep-dive discussions on the most interesting *technical* developments in Bitcoin from the past month. Participation by everyone is highly encouraged! Our goal is to foster lively discussion, knowledge sharing, and debate. In the weeks leading up to the event, participants gather topics such as: * New research papers * New BIPs and BOLTs * Network statistics * Technical blog posts * Mailing list and Delving Bitcoin threads * Pull requests and updates from key repos (Bitcoin Core, LND, Core Lightning, Eclair, BDK, rust-bitcoin, LDK, Electrum, …) Each topic is briefly introduced by our moderators and then discussed before moving on. The full list of links will be published at [bitdevs.berlin](https://bitdevs.berlin) 1–2 days before the event — please review them in advance to get the most out of the discussion. **Important details:** * This event is highly technical — best suited for those with a solid grasp of Bitcoin internals. Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at [bitdevs.berlin](https://bitdevs.berlin)). * Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings. * The evening begins with food and networking; people often stay after the seminar to keep talking. **Co-hosted by:** * [Felix](https://x.com/FelixWeis) * [Freerk](https://x.com/freerko) * [Fabian](https://x.com/fjahr) For background on the idea of BitDevs Socratic Seminars, see [this article](https://bitcoinmagazine.com/articles/op-ed-want-to-learn-about-bitcoin-try-a-local-socratic-seminar).

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.

Respect and Safety: There is always at least one organizer present at every meetup. If you ever feel unsafe or bothered by someone’s behavior, you can reach out to an organizer privately. Your identity will remain confidential, your concern will be taken seriously, and no inappropriate behavior is tolerated — anyone making others feel uncomfortable will be removed from the group immediately. We hope to see you there. Bring yourself, your smile, drawing materials, your stories—or just your comfy self. Let’s make Saturday a little more laid-back, a little more social and a lot more nice. See you soon! —Your Saturday Creative Coffee Crew ☕
