Liebe JUG-Mitglieder, wir möchten Euch herzlich zu unserem nächsten Stammtisch, der jeden ersten Dienstag im Monat stattfindet, einladen. Alles weitere kann im unserem Blog unter http://www.jug-berlin-brandenburg.de/ gefunden werden. Viele Grüße Sandra, Jan, Jörg und Oliver

Looking for a low-pressure way to get offline, meet new people, and actually do something fun on a Tuesday? This is a relaxed pool night in Spandau—come for a few rounds, stay for the chats, and leave with a couple of new familiar faces. **What to expect** * Casual pool games in **rotating rounds** (so everyone gets to play) — **beginners are welcome** * A friendly vibe: meaningful conversations *and* a bit of playful pool-table silliness * We **start on time** — please arrive punctually, otherwise it’s hard to fit you into the rotation **Costs** * Your own drinks + shared table costs (depending on group size) **RSVP** Please RSVP on Meetup so I can estimate how many tables we’ll need.

New Starting Time: 12:00 For space reasons, we are limited to a certain number of attendees, so please update your RSVP if you can't come. If you are new, come and say hello, as we know that suddenly going quiet for 45 minutes and staring at that blank page can be intimidating when it's your first time. We have a lot of long-term regulars who will be happy to help you feel welcome. In between sessions, we have a Telegram chat: https://t.me/joinchat/ERW3pxD5kfELGeWs9SUhjw For more information, visit [https://shutupwrite.com](https://shutupwrite.com/).

We are back in the c-base! Do you already run NixOS and want to talk to other people or want an introductory session with some NixOS users. Just bring your machine! Usually there are no topics, we just sit in front of our computers, talk about stuff, debug some problems or review some PRs on nixpkgs. There are drinks usually available from the c-base bar. If you can't find us. just ask around or ask in irc (#krebs on hackint)

**OpenClaw Anonymous Berlin** Informal meetup for people interested in OpenClaw/Clawdbot and AI agents. No talks or presentations. Bring your ideas, questions, experiments, and half-working setups. We’ll compare workflows, share what’s working, what’s breaking, and what we’re trying. Come as you are. Stay as long as you like. Bring your laptop if you feel like it.

In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

Diesmal werten wir die Performance des Musterdepots meiner Gruppe "[Souveränes Vermögen – Der Club für Langfrist-Investoren](https://www.meetup.com/de-DE/dieinvestoren/)" im ersten Quartal 2026 aus. Was lief gut, was lief schlecht und warum lief es gut oder schlecht? Welche Regeln haben sich bewährt und welche sind überflüssig? Müssen wir Änderungen vornehmen? Spannend für alle, die einem Investitionsprozess über die Schulter schauen wollen während er entsteht.

***Get ready to explore the beauty of nature on a quick sketch walk - no art skills needed, just your creativity and love for the outdoors!*** **HOW DO I JOIN THIS EVENT?** Click on link below to get complete info and to sign up for this event by getting your ticket. [https://urbanaturetravel.com/event/quick-sketch-grunewaldsee-12apr2026](https://urbanaturetravel.com/event/quick-sketch-grunewaldsee-12apr2026) **SPECIAL OFFER FOR NEW USERS** * 10% New User Discount using promo code: **MEETUP10** * Valid for this trip or any other trips available on our website. **WHY GO?** * Join us, the afternoon of Sunday, the 12th of April the König-Louise-Straße Bus Stop near the Waldbaude Snack Bar (Clayallee 91, 14195 Berlin). We’ll be meeting up with fellow ***Sketchers & Artists*** to practice our ***quick sketching skills while enjoying nature,*** we’ll be walking a short ***2-3 kilometers*** into Grunewald, and along the Grunewaldsee. Nature is slowly waking up from its winter slumber, with moss, ivy and pine being the primary shades of green you’ll see. We’re taking this opportunity to do a series of ***quick sketches focused on shading***. You can draw what you choose, or even bring a camera to do some photography as well. As the trees are mostly still without their leaves, ***we’ll be focusing on details like moss covered logs, small wooden bridges, a sandbar along the lake and reeds growing at the lake shore***. You will also have the opportunity to sketch a scene of the ***Jagdschloos Grunewald***, seen best from across the lake due to ongoing construction. * If this is your first time sketching or 100th time sketching, you can find subjects that are right for you. ***You don’t need to be a professional at all!*** You should just want to practice your sketching skills while meeting new people, and hopefully sketching a bit better than you did the day before. * If this is your first time to Grunewaldsee, please be aware many locals have their dogs off leash in the area. * We will be stopping to do multiple 15 min sketches with the goal of improving our quick sketching skills. ***Quick sketching is a foundational sketching skill*** that seeks to simplify a scene while communicating the necessary details for a viewer to see and feel a scene or detail. This weekend, we’ll be focusing especially on the art of shading, and how it can be used to add a little extra pop to our sketches. These are sketching skills that can be applied across artistic mediums. * Bring your preferred drawing medium for short ***quick sketches***, and meet up with fellow nature sketchers. There are benches in the area, but you may wish to bring a small chair or cushion to make things more comfortable. * The drawings are purely for fun, and to get to know other artists and hobbyists in the area! * (This meet-up does *not* include entry to the Jagdschloos Grunewald) * Join us at 13:00 at the König-Louise-Straße Bus Stop (115, X10, N10, X83) near the Waldbaude Snack Bar (Clayallee 91, 14195 Berlin) with our host - Elizabeth, we’ll get to know one another and then set out as a group to sketch along the Grunewaldsee, it’s an out-and-back route along a lake with several opportunities for sketching, conversation and relaxing. We will sketch from 13:00-16:00 and then return to our meeting spot. ### 📲 Stay Connected Please do join our **WhatsApp / Telegram channels** for: * Event updates * Future trips & meetups * Early-bird discounts * Contests & giveaways 1.

OBS! Normally these events take place on the FIRST THURSDAY OF THE MONTH, however due to Easter we will be hosting it on the SECOND THURSDAY of the month this time. **Meaning, the event will be on the 9th of April instead of the 2nd.** Nico Caramella breaks down the strategy of placing sponsored "best X" articles on high-authority third-party publishers. Join us on April 9th, for an exciting and highly relevant session! For anyone looking to expand their knowledge on how to get noticed and build their presence in AI-recommendations , this will be an important one to attend. The session will be held at the **Buzzmatic Office, Schönhauser Allee 149**, from **9:30 to 11:00**. Enjoy **free attendance,** some lovely **breakfast** and great conversation! Nicolas Caramella, CEO and Founder of [GetCited.de](http://getcited.de/ "http://getcited.de/"), will come to the Buzzmatic office and do a session on How "Best X" Advertorials Get Your Brand Recommended by AI. *Nearly half of every AI answer about software, products, or services traces back to one content format: "Best X comparison listicles". In this session, Nico breaks down the strategy of placing sponsored "best X" articles on high-authority third-party publishers to systematically build brand presence in AI-generated recommendations. Whether you do this for clients or want to understand the emerging discipline of AI visibility, this talk gives you the framework and the data.* In May we will be welcoming Andrés Tapia as our next external speaker, to do some deepdives on related topics. We will be posting more about this soon, so stay tuned! Bring yourself, a good mood and any thoughts or questions you have on the subject. We look forward to seeing you there and hearing your thoughts!

**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).

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.
