Most developers never see the switch happen. In this talk, we'll explore how mutex work under the hood and how the runtime decides which face to show. Through a series of benchmarks, we'll observe mutex behavior under increasing contention and across different core counts to see both modes in action. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-april-golang-meetup-2/.

Ein späterer Einlass ist nicht möglich, weil wir mitten im Flow sind. **Vielen Dank Dir** 🙏🏽 \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Menschen mit guten Freunden leben länger, glücklicher und gesünder. Außerdem machen gute Freundinnen einfach Spaß.** . Deshalb biete ich Freundschaftsworkshop an. . Manche sagen: "Es ist schwierig, in Berlin gute Freundinnen zu finden." Berlin, die Stadt der 1000 Möglichkeiten ... ich kenne das auch. . **🌸 Dann machen wir einen Workshop!** 1. Maximal 40 Frauen. 2. Eine leichte Moderation führt durch den Abend 3. Ihr lernt Euch kennen und habt Spaß. 4. Wer mag, trifft sich wieder. . Du wirst überrascht sein, wie vertraut Du mit vielen nach 3 Stunden sein wirst - so, als ob Ihr Euch schon lange kennt. . **🔱 4 Jahre Arbeit - 1 Workshop** Vier Jahre habe ich geforscht und ausprobiert, wie Menschen Freunde werden & was die Magie der Freundschaft ausmacht. Das Ergebnis ist dieser Abend. . Praxisnahe, schnell umsetzbare Tipps, die Du schnell in den Alltag umsetzen kannst. Kleine Happen zur Theorie. - Und vor allem: Kennenlernen & Spaß haben. Wir probieren einfach miteinander aus. . Eine Teilnehmerin sagte mal zu mir: * "Georg, das ist so eine angenehme Atmosphäre. Danke, dass Du das machst." . Was soll ich sagen? Stimmt. Das ist mein Anliegen 🤗. . . **🎁 Diese Methoden kannst Du in Deinen Alltag mitnehmen.** Ab sofort kannst Du Menschen besser und persönlicher kennenlernen – und damit tiefe Verbindungen und bessere Freundschaften aufbauen. . . **⏰ Die Türen sind offen ab 18:45 Uhr.** * Deinen Mantel aufhängen, WC, eine Runde schwatzen und los geht's... . **❓ Darf ich wiederkommen?** Es gibt nur wenige Veranstaltungen, bei denen man wirklich miteinander ins Gespräch kommt. Hier schon, mit Tiefgang. . Einige kommen immer wieder, um die Details des gut gestrickten Programms zu ergründen - und immer wieder neue Menschen kennenzulernen oder auf bekannte Gesichter zu treffen. . Bis es endlich Klick macht und die richtigen Freundinnen gefunden sind. . . **🎒 Was bringst Du mit?** * Etwas zu trinken (z.B. deine Wasserflasche, keinen Alkohol!) * Du solltest satt sein und vorher gegessen haben * Bargeld für den Eintritt [oder [Ticket von Eventbrite](https://www.eventbrite.de/e/nur-fur-frauen-neue-freundinnen-in-berlin-workshop-tickets-1980673646194?aff=MeetupApril)] . **🏠 Der Veranstaltungsraum** * Wir haben einen wunderschönen Raum im Prenzlberg - im Life Artist Hub * Gut mit Öffis zu erreichen: Schönhauser Allee (Ringbahn, U2, M1), Eberswalder Straße (U2, M10, M12) * Vor Ort ist alles ausgeschildert. . **Vorsichtshalber hier die Wegbeschreibung:** * Du gehst in den Hof bis nach hinten durch. Dort ist eine Tür. * Du klingest bei "Life Artist Hub". Die Tür sollte sofort summen. Öffne die Tür. * Du gehst in den 3. Stock. Da sind wir. 🤗 . **👱🏽‍♂️ Warum moderierst Du als Mann diesen Workshop?** . Hi, ich bin Georg. Ich weiß, ich bin ein Mann. Warum moderiere ich dann diesen Workshop? . Abenteuer Freundschaft ist mein Beruf. Am Anfang war ich auf Männer-Freundschaften spezialisiert. Überraschenderweise waren 60 Prozent der Newsletter-Empfängerinnen Frauen. Frauen scheinen die Wichtigkeit guter Freundschaften viel mehr zu spüren. . Deshalb habe ich letztes Jahr angefangen, Workshops für Frauen anzubieten. Soziale Träger, das Rathaus Schöneberg und das Frauenzentrum Begine haben mich bereits für Freundinnen-Workshops gebucht. Im Frauenzentrum moderiert eine Bekannte die Workshops.... denn da darf ich noch nicht mal rein :). . Unseren Workshop werde ich zurückhaltend moderieren. Ich weiß mit der Situation umzugehen. Das ist Euer Raum. . Für die Männer gibt es alle zwei Wochen am Dienstag einen Männer-Workshop, der regelmäßig gut besucht ist. . . **Mehr über Abenteuer Freundschaft & mich:** 🌎 [www.abenteuer-freundschaft.de](http://%5Bhttps://www.abenteuer-freundschaft.de/%5D(https://www.abenteuer-freundschaft.de/) "\[https://www.abenteuer-freundschaft.de\](https://www.abenteuer-freundschaft.de)") . . **👋🏽 Get in touch & stay in touch:** . **✈ Telegram-Kanal: [t.me/abenteuer_freundschaft](http://t.me/abenteuer_freundschaft)** für Events, Workshops & Neuste Erkenntnisse aus der Freundschaftsforschung (Überschriften) . **✉ Freundschafts-Newsletter:** [https://abenteuer-freundschaft.de/newsletter](https://abenteuer-freundschaft.de/newsletter) Alle 4 Wochen das Neuste aus der Freundschaftsforschung; oft seltener, denn ich schreibe nur dann, wenn es wirklich etwas zu berichten gibt. . **🔥 6 Zutaten großartiger Freundschaften** Seit 2020 forsche ich, was großartige Freundschaften wirklich ausmacht.

"Ich bin ein bunter Hund und habe viele Bekannte. Aber eine Bekanntschaft zur Freundschaft machen - das hast Du mir gezeigt." . "Ich war nervös, ob ich wirklich kommen soll. Was sind da für Leute? Mit wem verstehe ich mich? Nach einer Stunde war mir klar: Gute Freundinnen sind gleich. Ich muss mich nicht mit jedem verstehen. Und allein für die Methoden hat es sich gelohnt. Dankeschön!" .

Join this **Interview Simulation** session — to sharpen the skills for both interviews and architectural pitches. This time we meet in the Monbijou park. 💡 How it works The event is split into three parts: 1. **Answers for common behavioral questions** \- at the beginning\, I will read some common interview questions\, explain what they mean\, and give the correct answers\. 2. **Interview Simulation (10 minute rounds)** – One participant acts as the interviewee and answers a round of behavioral and design-focused questions. Each other participant gets to ask him one interview question. 3. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) * **Technical questions** (based on your tech stack) * **Light design problems** (high-level reasoning, not code) No need to prepare anything in advance — just bring curiosity and an open mind. Bring your CV if you’d like feedback from others.Job searching can take a lot of energy, make sure you are taking care of yourself as well, and share your story with the other participants.

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️‍🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity. This time, we have the following topics lined up: * Tobias has been working on a ***project wizard*** and would like to receive some feedback from the group. * Crop is going to introduce the topic of ***atomics***, then hold a discussion space for answering questions and sharing experiences. * Raf finally would like to introduce ***test-driven development*** with a small mob coding exercise. If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 16 April 2026 is our thirteenth meeting. Our next projected meetings are going to occur on the following dates: * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 * 1 Oct 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can.

View the session lineup and speakers at [Global Azure Columbus 2026](https://coazure.github.io/cbus-global-azure-2026/) On **Saturday, April 18, 2026**, the Azure Columbus Meetup, DevOps Meetup, and Code and Coffee Meetup are hosting our local edition of Global Azure 2026. This is a free, community-driven event packed with learning, networking, and all things Microsoft Azure. Whether you’re building modern cloud-native apps, experimenting with AI agents, deploying containers, automating infrastructure, or just beginning your Azure journey, this event is for you! **What to Expect** * Engaging technical sessions * Real-world Azure architecture & cloud-native patterns * AI, agents, automation, and modern DevOps * Food and drinks (because learning burns calories) * Time to connect with fellow engineers, architects, and cloud enthusiasts **Who Should Attend?** * Software engineers (any language, any stack) * Cloud architects * DevOps engineers * Data professionals * AI explorers * Platform builders * Anyone who loves solving hard problems with great tools If you build, deploy, automate, scale, monitor, or optimize in Azure, you’ll feel right at home. **Why Global Azure?** Global Azure is a worldwide community event where Azure user groups host learning sessions on the same day across the globe. It’s grassroots. It’s technical. It’s practical. And it’s powered by people who genuinely love sharing what they’ve learned. And yes, it’s free to attend!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
