Since there is no regular meetup, let's meet, talk and if we get fancy, perhaps write a line of code or two.

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.

BHNT 110: the third BHNT in 2026. The title is inspired by [Human brain cells on a chip learned to play Doom](https://www.newscientist.com/article/2517389-human-brain-cells-on-a-chip-learned-to-play-doom-in-a-week/) \- but also the doom and scrolling through it all around us currently\. Your hacks do not have to be connected to the title (bonus points if they do though) Please RSVP and bring your hacks! There are 8 dynamically allocated Slots that consist of 5min presentation + 5min conversation with the audience. To refresh your memories or get familiar with the concept - see some old hacks here: [https://bhnt.c-base.org](https://bhnt.c-base.org/) Hope to see you - looking forward!

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)

Come along, grab a coffee, shut up, and write! We will do at least two sessions of each 45 minutes of writing and two breaks. We will start the first writing session at 10:45. For space reasons we only allow a limited number of attendees, so please update your RSVP if you can't come. We'll probably be grouped around the large table in the back room's center. In the summer, also outside. Looking forward to seeing you there!

For International Women’s Day 2026, the global theme is **Break the Pattern**. Breaking the pattern means refusing to accept things simply because they’ve always been done that way. It’s about challenging outdated norms, disrupting bias, and stepping into spaces where women were not always expected. Technology shapes our world — but who gets to shape technology? Join us in Berlin for an inspiring evening hosted by **Women Techmakers Berlin in Collaboration with OJIN AixHaus** where we’ll explore how women and allies are challenging traditional paths in tech, redefining leadership, and building a more inclusive future. **✨ What to expect:** • Inspiring lightning talks from women in tech • Interactive discussions with the community • Networking with the Berlin tech ecosystem **✨ Agenda Highlights** **18:00 - 19:00** Registration, Pizza & Networking **19:00 - 19:15** Welcome words **19:15 - 19:35** Empowering Innovation: Building Inclusive Cultures for Women in Tech and Harnessing Their Unique Strengths **19:35-19:45** Break **19:45- 20:30** Panel Session: Break the Pattern - Tech Beyond the Default in the AI Era **20:30 -21:45** Networking **✨ Speakers** **Speaker:** [Shivany Powani](https://www.linkedin.com/in/shivany-powani/) Leader, Speaker, Program Management Lead **Panelists:** [Eva Hoffmann](https://www.linkedin.com/in/evamhoffmann/overlay/about-this-profile/) Engineering Manager at trawa [Soukayna Ikhiche](https://www.linkedin.com/in/ACoAACjVG_0Bc1OkM1HWT64lE4gH6cl9yKfh58c) Brand Marketing @Meta \| Brand Expert & Speaker [Tanja Kojić](https://www.linkedin.com/in/tanjakojich/overlay/about-this-profile/) User Researcher at Technische Universität Berlin Whether you're a developer, designer, product manager, founder, student, or simply curious about tech — this event is for you. 💡 Come share your story, connect with others, and reflect on one simple question: **What pattern will you break?** 📅 **Date**: March 31, 2026 📍 **Location**: Ojin AixHaus, Chausseestraße 36, 10115 Berlin 🎟 Free community event (registration required) Let’s challenge the status quo and shape the future of tech together. * **About Ojin** Ojin AixHaus is the new AI Playground in Berlin.

🌈✨ A Space to Be Fully Yourself Without Masking ✨🌈 For many neurodivergent queer women, everyday life can be deeply isolating. The constant effort to mask. The feeling of being too much or not enough. The sense that no one really sees your individual struggles. It’s exhausting. This space exists to break that isolation. It’s a safe place where neurodivergent queer women can show up exactly as they are. No masking. No explaining. Just real connection with others who understand what it’s like to navigate the world differently. It’s that time again Our monthly meetup is here and it’s your chance to connect, recharge and feel seen. 💬💞 You’ll mix and mingle with others through fun conversations, little mindfulness excersises and shared conversations about both the struggles and the superpowers that come with being neurodivergent. 🌟 Spots are limited and demand is often high. To help make sure that people actually show up and don’t take a spot from someone else, we’re asking for a small entry fee. 💌 If you’re not in a position to pay right now, just reach out. We’ll make sure you can still join. We’re looking forward to seeing you Just as you are

Hello everyone, Due to popular request (and some other reasons, like venue availability and available organiser capacity), we’re happy to announce that the Rust Berlin talk meetups are back. This is the classic meetup format: let’s meet in the evening see 2 speakers and then spend some idle time chatting about what we heard. The first speaker for the first edition will be our co-organiser Florian Gilcher, speaking about “Unsafe demystified”, a gentle introduction into handing unsafe code properly. Soares Chen will talk about the current revision of Context Generic, their framework for context generic programming: https://contextgeneric.dev We are also available for new talks, in particular of people who never gave a public talk. We’re happy to be your first talk location. The new meetup is currently organised by Florian and Liran, who is a new co-organiser at Rust Berlin. JetBrains was so kind to offer us their office location as a default meeting point. Thank you! We’re looking forward to getting the ball rolling again! See you all on April 1st! **Line-Up** Unsafe demystified by Florian Gilcher This is a beginner- to mid-level talk that explains the basics of unsafe and how to program it. Instead of going fully into it all details of unsafe, this talk teaches you easy to digest mental frameworks to use when approaching your next unsafe code block. Supercharge Rust functions with CGP implicit arguments by Soares Chen I will give a short overview of the new implicit arguments feature for Context-Generic Programming (CGP), which enables structural typing in Rust. Some short example demos will be presented, followed by some explanation of how the feature works. **Speaker Bios** Florian Gilcher Florian Gilcher used to be part of the Rust team at several positions and served as a member of the Rust Foundation board. He is also a co-founder of the Rust Berlin meetup. Today, he’s training Rust at Ferrous Systems, a company he co-founded. Soares Chen Soares is a Rust programmer with a strong interest in functional programming, type theory, and programming language design. He is the creator of Context-Generic Programming and currently works as a Rust engineer at Tensordyne.

Network every first Friday of the month with professionals from diverse disciplines, industries and cultures. We share wine, food and our experiences.

Mit dem Titel "Philosophie 2.0" wird nicht zu viel versprochen. Nicht alles was mit 'Philosophie' bezeichnet wird, hat damit auch zu tun. Das gilt allgemein. Wörter werden zu oft nicht präzise gebraucht, aber wenn man alles mit beliebigen Wörtern bezeichnen würde, könnte man nichts mehr genau verstehen, könnte nichts mehr genau begreifen. Also blieben die Irrtümer bestehen. Das hätte mit Philosophie aber definitiv nichts mehr zu tun. Was also ist das Gegenteil belanglos-vieldeutigen Wörterverdehens mit hochassoziativen Sprüngen bei denen allerlei übersehen wird und ergo das Wesentliche nicht mehr als solches klar erkannt werden kann? Maximal exakte Begriffsklärung. Und das geht! Das geht über einen systematischen Aufbau aller Kategorien - gestützt über einen Algorithmus, welcher Kategorienfehler automatisch vermeidet und mithilft, das Ganze im Blick zu behalten. Dass dies für uns Personen gar nicht so einfach ist, sieht man daran, dass jede Person (auch Du) irgendwann irgendwelchen Irrtümern aufgesessen ist. Jede Person, die sich also für irgendetwas ernsthaft (nicht wegen blanglosem Amüsement, oder wegen ideologischer Rechthaberei) interessiert und ergo dafür offen ist seine Auffassungen weiterzuentwickeln, ist bei dieser Veranstaltung goldrichtig. Ablauf: Bei unserer Diskussion geht es dabei nicht um irgendein festes Thema, sondern jeder schreibt ein Wort in seinem Interessengebiet auf einen Zettel und wir ziehen diese paarweise für je eine Runde. Die beiden Wörter haben gemeinsame Kategorien, aber es gibt auch Unterschiede. Wer diese nicht alle kennt, kann nicht behaupten, dass er tatsächlich begriffen hat, wovon er meint, dass es ihn interessiere; dass er definitiv wüsste wovon er spricht. Dieses Problem hatte schon Sokrates erkannt. Nur haben wir jetzt einen Algorithmus, welcher zu absoluter Genauigkeit verhilft um diese Irrtümer loszuwerden. Daher 'Philosophie 2.0'. Siehe dem Bild oben werfen wir die Bedeutung (die Menge aller Kategorien einer Begrifflichkeit) per Beamer an die Wand. Wir sind nicht in der Schule, d.h. es gibt keinen Zeitdruck, keine Noten, keinen Wettbewerb und keine Profilierungsmotive, sondern jeder hat alle Zeit der Welt um über die schematisch dargestellte Bedeutung nachzudenken - und diese zu hinterfragen. Die grafisch dargestellten Bedeutungen des Algorithmus sind nicht perfekt. Es geht nicht darum irgendetwas zu akzeptieren, sondern andersherum: die Bedeutung anzugreifen und zu verbessern. Jeder kann sie ändern! Die Diskussion ist also eröffnet. Jeder muss Gründe angeben. "Kann ein Walfisch ein Wellensittich sein?" \~> Natürlich nicht, denn Säugetiere sind keine Vögel. "Kann ein Fenster ein Getränk sein?" \~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten. "Kann eine Demokratie eine Republik sein?" "Kann eine Vermutung eine Meinung sein?" "Ist etwas zu begreifen das Selbe wie etwas zu verstehen?" Nichts regt dermaßen zum nachdenken an wie die Bedeutung der Begrifflichkeiten algorithmisch stabilisiert zu systematisieren. Und wenn wir uns nicht einig werden? Die Diskussion läuft auch nach der Veranstaltung weiter. Jeder kann online von zuhause die Diskussion fortführen - mit dem selben mitdenkenden Algorithmus. Man könnte sagen, es sei ein neues Gesellschaftsspiel - ohne Wettkampf, sondern in kollektiver Bereicherung an Klarheit, von der alle gigantisch profitieren, obschon jeder nur einen sehr kleinen Teil beiträgt. Das "Spiel" funktioniert auch mehrsprachig, denn der platonische Raum der Begrifflichkeiten ist der eindeutige Raum, auf den das Vokabular einer Sprache nur referiert. Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren. Bring deinen Laptop mit, dann wird es einfacher... Dieses Spiel macht klug: Schach trainiert zwar das Konzentrationsvermögen, hat aber mit der Wirklichkeit nichts zu tun. Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden. Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger. Mach mit!

**We are expanding our creative programming opportunities with Queer Quills, a quiet writing and sharing space. Queer Quills features some prompts, supplies and friendly faces to help get some inspiration or feedback for your writing. Hope to see you there!**

⚠️ **IMPORTANT: You must sign up and buy a ticket here to attend:** [https://groupvibe.com/](https://groupvibe.com/) **Join the Columbus City Brunch Club and make new friends!** Each meetup brings together 4–6 people for casual conversations over brunch. We use the Groupvibe platform to facilitate the meetup and ensure everyone’s a good fit. 👉 **To attend, you’ll need to complete registration via this link:** [https://groupvibe.com/](https://groupvibe.com/) We’ll share the exact location of the upcoming meetup the night before only if you have bought a ticket or membership plan. **Why this works:** \* Smaller groups make real conversations easier. \* Discover new restaurants in your city, together. \* Curated lunch venues with good food and vibe. \* If you hit it off with your group, there’s plenty of time to hang out afterwards. **Note:** RSVPs on Meetup don’t reflect total attendance. Many attendees register directly via our website. The event on [Meetup.com](http://meetup.com/) is only a placeholder. This meetup is organized by Groupvibe, a small team passionate about helping people form meaningful friendships offline.

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.
