Open Sharing Circle ✨ *** **Wichtig: Bitte sei pünktlich, damit der Austausch möglichst nicht gestört wird :)** Wir sind draussen bei der Blatterwiese. Es wird sonnig und warm werden. Zuerst machen wir einen Sharingcircle und danach klingen wir den Tag aus mit Spielen (Brettspiele, Spikeball, acrojoga etc) und BBQ. Nimm dein Lieblingsspiel mit, wenn du eines hast, wie auch Essen für dich. _____________ Dieser Circle findet auf Deutsch statt. Wir kommen zusammen, um im Moment präsent zu sein und uns so zu zeigen, wie wir wirklich sind. Die Intention ist, in einem sicheren und vertrauensvollen Raum zu teilen — Gedanken, Emotionen, Ziele, Meinungen — alles, was sich für dich im Moment lebendig anfühlt. Niemand muss etwas teilen, und jede\*r ist willkommen. ⸻ Worum geht es? • Stärkung von Selbstwahrnehmung & Selbstvertrauen • Persönliches Wachstum • Aufbau tiefer Beziehungen & Vertrauen • Menschen auf einer echten, menschlichen Ebene kennenlernen • Sich frei fühlen, sich authentisch auszudrücken ⸻ Circle-Vereinbarungen Frei & freiwillig Du darfst alles teilen, was du möchtest — und musst nichts teilen. Sprich aus deiner eigenen Erfahrung Teile aus deiner persönlichen Perspektive: deine Erfahrungen, Gedanken, Gefühle und Wahrnehmungen. Der Raumhalter kann dich dabei sanft unterstützen, indem er als Zeichen eine Hand auf die Brust legt. Respekt & Vertraulichkeit Wir begegnen uns respektvoll und ohne zu urteilen. Was im Circle geteilt wird, bleibt im Circle. Rede-Objekt Nur die Person, die das Rede-Objekt hält, spricht. Verständnisfragen sind willkommen. Redezeit & Raum teilen Nimm dir Zeit beim Teilen und lass gleichzeitig Raum für andere. Ratschläge & Unterstützung Sprich für dich selbst und gib Ratschläge nur mit Einverständnis. Bitte frage ausdrücklich nach, wenn du Ratschläge oder Unterstützung möchtest. Trigger & Emotionen Jede\*r ist für die eigenen Gefühle und Themen selbst verantwortlich. Starke Emotionen (z. B. Weinen) sind willkommen und werden respektiert. Unterstützung wird nur angeboten, wenn sie gewünscht ist. Eigene Bedürfnisse Kümmere dich selbst um deine Bedürfnisse (WC, Essen usw.) und respektiere den Gruppenraum. Raumhalter Das Organisationsteam wählt Raumhalter, die den Ablauf des Circles unterstützen und darauf achten, dass die Vereinbarungen eingehalten werden. Der Circle kann bei Bedarf sanft unterbrochen werden. Fokusrunde Der Raumhalter kann intuitiv eine kurze Fokusrunde initiieren, wenn es unterstützend wirkt. Mobiltelefone Bitte schalte dein Handy auf lautlos und nutze es nur für Notizen, falls nötig. Zeit Dauer: ca. 3 Stunden. Du kannst jederzeit gehen, idealerweise während der Pausen (etwa alle 45 Minuten). Nach dem Circle gibt es Raum, um zu bleiben, sich zu verbinden oder weiter zu teilen, wenn du magst. Teilnahme CHF 5 Basisbeitrag + freiwillige Kollekte. Damit unterstützt ihr Organisation und ermöglicht es uns, den Sharing Circle möglichst vielen Menschen zugänglich zu machen.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!

This group is brought to you by the Dianetics and Scientology life improvement center.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
