**Topic: In Defense of Tech Monopolies: A Debate You Weren't Expecting** Are tech monopolies really the villain everyone makes them out to be? In this session, we'll explore the counterintuitive argument that concentrated tech power can drive innovation, create better developer experiences, and produce more stable ecosystems. Think about it - would we have Android without Google's scale? Would open-source AI flourish without Meta's resources? We'll lay out the strongest case for tech monopolies, then break into groups to stress-test, challenge, and debate whether big tech consolidation helps or hinders the software community. **What to Expect:** * A concise, 5-10 minute expert presentation introducing us to the nuances of the topic. * Engage in insightful discussions with fellow participants in breakout groups, exploring diverse experiences and practices. * Dive into prepared questions designed to challenge and expand your perspective on the topic. * A fantastic opportunity to network with like-minded professionals and enthusiasts passionate about software development and team building. *** **Broadening Our Discussions:** We explore a wide range of topics, including Extreme Programming (XP), agile management methods, lean theory, career management, programming katas, and other areas related to software development. Whether you're new to software, a seasoned practitioner, or an expert, your insights and experiences are valued here! *** **Event Details:** We'll gather from 7:00 PM, officially start the session at 7:15 PM, and take a break at 8:30 PM to decide the topic for our next session. Don't miss this chance to learn, share, and connect!

This is an [in-person communication lab](https://www.presentation-school.com/berlin-presentation-lab) that helps professionals speak clearly and confidently under pressure using proven methods. Most people don’t struggle because they don’t practice enough. They struggle because they practice without the right principles. This session focuses on deliberate, guided practice informed by performance psychology, neuroscience, and modern communication training. **What You Will Do** * Learn one science-based communication principle that improves real-world performance. * Train that principle in structured speaking exercises designed for skill development. * Receive clear, professional feedback you can apply immediately. Practice and feedback are guided by experienced communication professionals who work with executives and senior professionals. This is not peer-to-peer feedback or open discussion. **Who Should Attend?** * Non-native English speakers * Professionals who present, lead meetings, or speak up at work * Anyone who overthinks, freezes, or loses clarity under pressure * People who want structured improvement, not just repetition No prior experience is required. **What This is NOT** * A lecture. * A motivational talk. * A public performance. * Unstructured open practice. * Peer-led feedback or opinion-based critique. **Before The Session** Before the session, participants complete a short preparation form to clarify their goals and common communication challenges. This helps ensure the practice and feedback during the lab are as relevant and effective as possible. **Optional:** Participants may submit a short video (1–2 minutes) or written questions. This is optional and used to personalise focus areas and examples during the session. No individual coaching is provided. **After the Session** Participants receive a short follow-up pack with key takeaways, practical drills, a reflection question, and guidance on next steps. **Practical Information** Language: English Duration: 2 hours Format: In-person, structured group lab Address: Chausseestraße 86, 10115 Berlin Healthy snacks and water provided. Price: €25 per session If you are looking for a professional, practical way to improve how you communicate and want to train using principles that actually lead to results, this lab is a good place to start.

Liebe Meetup-Community, schön, dass du hier bist. Suchst du gerade nach einem neuen Funken für dein Leben? Pass auf: Diese Veranstaltung wird dich vielleicht nicht nur unterhalten und inspirieren – sie könnte deine Sicht auf die Dinge (und damit dein Leben) grundlegend verändern. Wenn du bereit bist, lies weiter. **Findest du dich in einer der folgenden Situationen wieder?** * **Frust trotz Erfolg:** Du (und vielleicht dein Partner) hast eigentlich alles „richtig“ gemacht – Studium, Karriere, gutes Gehalt. Aber durch die Inflation und steigende Kosten fühlt es sich nicht mehr selbstverständlich an, eine hohe Lebensqualität zu führen (beim Einkaufen, beim Urlaub buchen oder beim Eigenheimkauf). Hinzu kommen Bedenken über die Altersvorsorge aufgrund des aktuellen Rentensystems. * **Was nun nach den ersten Schritten?** Du hast dich schon an Aktien, ETFs, Krypto, Immobilien usw. herangetraut, aber der Weg zu deinem Traumleben sieht noch unendlich weit oder ungreifbar aus. * **„Selbst“ und „ständig“:** Du hast den Schritt in die Selbstständigkeit gewagt, fühlst dich aber gestresst – sei es wegen der Finanzen, dem Zeitmangel für dich und deine Familie oder beidem. **Stell dir vor, du gehst nach diesem Abend so nach Hause:** * **Antrieb:** Du erkennst, dass dein eigentlicher Traum, den du vor Jahren in die Ecke geschoben hast, doch möglich ist. * **Klarheit:** Du weißt jetzt, was dein nächster Schritt ist – und du hast richtig Lust, ihn zu gehen! * **Freude:** Du stehst am nächsten Tag nicht mehr aus Pflichtgefühl auf, sondern aus echter Freude. **Was wir machen:** Wir treffen uns in lockerer Runde und spielen das **[Cashflow-Spiel von Robert Kiyosaki](https://en.wikipedia.org/wiki/Cashflow_101)**. Keine Theorie, sondern Spiel bzw. Simulation pur. Wir probieren auf dem Brett Sachen aus, die man im echten Leben vielleicht gar nicht sieht oder sich nicht traut – und lernen dabei extrem viel über unser eigenes Geldverhalten. Wir lachen viel, tauschen uns ehrlich aus und kommen als Gruppe weiter. **Der Plan:** * **18:30 Uhr:** Ankommen, Drink schnappen, kurz quatschen. * **19:00 Uhr:** Spielstart (ca. 90 Min.). * **Danach:** Offene Runde. Wir reden Tacheles – über Aktien, Krypto, Immobilien und deine persönlichen Erfahrungen. Steig ein – spielerisch, ehrlich und vielleicht ist das hier der Startschuss für dein neues Leben. Beste Grüße und bis dann, Shuying ========================================== **Wer wir sind:** Wir sind eine vielfältige Gruppe von Menschen, die entdeckt haben, dass strategisches Aktienhandeln für jeden zugänglich ist. Unser Ziel ist es, unsere gemeinsame Erfahrung zu teilen und Anfänger im Aktienhandel zu inspirieren, sich sinnvoll und emotionsfrei zu investieren. Wir glauben fest an das Konzept des gegenseitigen Lernens – indem wir dir helfen, lernen auch wir von dir, und schaffen so eine Win-Win-Situation für alle. **Was wir glauben:** * Erfolgreiches Aktienhandeln ist keine exklusive Domäne für Finanzexperten. * Das Verstehen von Aktien und das Treffen informierter Anlageentscheidungen ist für jeden erreichbar. * Du benötigst keinen Abschluss in Betriebswirtschaft, um die Prinzipien der Wertanlage zu verstehen. * Technische Aktienanalyse ist nicht nur für Finanzprofis gedacht; es ist eine Fähigkeit, die du erlernen kannst. **Über die Gründerin dieser Meetup Gruppe:** Shuying hat Mitte 2023 selbst ihren Weg zur Anlegerin gefunden – von der Frustration und Überforderung zur begeisterten Aktieninvestorin, nachdem sie die Grundlagen der Chartanalyse gelernt hatte. Inspiriert durch diese Erfahrung gründete sie diese Meetup-Gruppe, um andere auf ihrem Weg zu mehr Selbstvertrauen, Klarheit und finanzieller Freiheit zu unterstützen.

Meinungsaustausch, Investmentideen, Buchbesprechungen, Charttechnik, Fundamentalanalyse. Wir diskutieren über die Themen Börse, Investment und Trading. Verkehrssprache ist deutsch. Egal ob Anfänger, Profi oder "will nur mal gucken": jeder ist willkommen und kann mitreden. Die Veranstaltung ist insbesondere geeignet für aktive Händler in Einzelaktien, Optionen und Rohstoffen. Es geht viel um technische Analyse und technische Markteinschätzung, aber auch um fundamentalanalytisch basierte Einzelaktienauswahl, Volatilitätshandel und Optionshandel. Es gibt ein Musterdepot, dessen Struktur und Performance als Diskussionsgrundlage dienen soll. Jeder kann seine Meinung dazu äußern. Das Musterdepot findest Du bei wikifolio.com unter https://www.wikifolio.com/de/de/w/wf000bit01 Meinen Youtube-Kanal findest Du hier: https://www.youtube.com/channel/UCCmOeA2-rAS2P8YZNp11N6Q Kryptowährungen spielen thematisch nur eine untergeordnete Rolle. Der Kurzvortrag mit Diskussion startet pünktlich 17.15 Uhr. Wer viel Aufmerksamkeit braucht, kommt einfach zu spät und wird von allen angeschaut :-) Wer noch Kontakte knüpfen oder quatschen möchte, sollte schon ca. 16.30 Uhr kommen. Die Veranstaltung endet püntklich um 19 Uhr.

Today we are working in a beautiful location at Alexanderplatz with desks, power sockets, free WiFi, available food/drinks and air conditioning.

**Complex Trauma Support Group** Our group is intended for survivors of complex trauma. If you are here, it’s likely that so much of who you are and what you have experienced in this life is actually invisible to most people––to family, society, coworkers, and the people who are around you. We are a peer-led group of survivors creating opportunities for ourselves and others to share our experiences, share support, and build relationships in kind community together. Survivor experiences might include: child sexual abuse, incest, child trafficking, and other experiences of people living with traumatic dissociation and complex PTSD. **What to expect at your first meeting:** Currently, we are offering a bi-monthly in person group at 2:00pm on the first and third Sunday of the month. The only criterion for joining the group is that you are a survivor of trauma wishing to have more kindness in your own life and share kindness with others, and that you agree to practice to group’s relational agreements available for view here: https://www.kindgroups.com/agreements. Joining the group is free of charge. We ask that new people connect with us for 30 minutes on the phone or on zoom before coming to their first group, so that we can determine together that we are a good fit. Our meetings last approximately 90 minutes. Participants are never required to share. You’re also welcome to choose a pseudonym and you will never be asked for private information. You are welcome to leave at any time. The kindness that survivors can share when among others who have survived similar childhood experiences is something we rarely get to experience. Time spent with others who understand even a little bit more about us is a relief. Our hope is to help ourselves and others experience that we are not alone. We wish for our efforts to be a cause of kindness in our own lives and the lives of each other. You can read more about the groups at www.kindgroups.com.
