Game Programming

**New to the game? Please join our beginner-friendly Sunday event instead!** Hi folks, this is a special meetup group for the regular Blood on the Clocktower games every Tuesday in Berlin Mitte. This event is aimed at players who are already very familiar with Clocktower - if you have dozens of games under your belt and are excited to play custom scripts with other seasoned players, this is the event for you! Our group aims to provide a fun and welcoming space to experience this thrilling game of social deception. **We focus on promoting a positive and fun group atmosphere, where players don’t take themselves or the game too seriously, whether they’re heroically winning or spectacularly losing.** Our players follow the code of conduct for the Berlin Board Gamers group and are expected to treat each other with respect and consideration – “killing with grace, and dying with dignity”. If you are marked as "going" in Meetup and are in your seat at 19:00, your place is guaranteed. All other seats are first come, first served. There is a €3 entrance fee per person to cover the cost of hiring the venue, payable in cash. We play in English so players should be able to understand and express themselves in English: an exception is possible for one pair of players willing to play together (as a “Revolutionary” pair) where one player can interpret into and out of English. Please let us know in advance if this is the case.

Come play Magic's most accessible competitive format! We meet every Tuesday at 18:30 at RuDi-Das Stralauer Kultur- und Nachbarschaftszentrum in Friedrichshain, \~10 minutes by foot from Warschauer Str. and Ostkreuz. **The best way to get in touch is to join the WhatsApp group:** https://unlock.ly/I7IhAbb *Even if Meetup has only 1 or 2 RSVPs, we are normally 20-30 people every week!* **FAQ:** **Do I need my own deck?** No, people that come bring extra decks, and you are free to borrow one if you want to test the format before buying into it! **Casual or Competitive?** We play casually to allow people to come late and leave early. Feel free to stay for any amount of time between 18:30 and 22:30. To this end, feel free to bring proxies, as long as it is clear what card you are proxying! **Why do you charge an entry fee?** Our 2 euro entry fee is a donation to the community center that we use to host our event.

The next **Berlin C++ Meetup** hosted by think-cell takes place on **Tuesday, May 26**. Join us for an evening with the Berlin C++ community! This meetup is a chance to step away from your day to day work, meet other developers, exchange ideas, and have real conversations about modern C++ in a relaxed setting. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ## **Talk** ### **Contract assertions on virtual functions** *Timur Doumler – Citadel Securities* Contracts assertions were introduced in C++26, but they cannot be applied to virtual functions. To close this gap, we first need to answer the question: how should contracts assertions behave in the presence of inheritance and runtime polymorphism? In this talk, Timur explores why this problem is harder than it looks. He reviews existing approaches from other languages, such as Eiffel, D, and Ada, highlights why they don’t fully translate to C++, and outlines the key design challenges involved. He then presents a concrete proposal for how contract assertions on virtual functions could work in C++, balancing correctness, safety, and usability. Along the way, the talk touches on good API design, the true meaning of the Liskov substitution principle, and how to reason about program correctness. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📅 **Date & Time:** Tuesday, May 26, 2026 – 18:30–21:30 📍 **Location:** Le Wagon Coding Bootcamp, Rudi-Dutschke-Straße 26, 10969 Berlin 🕒 **Agenda** 18:30 – Doors open 19:00 – Talk + Q&A 20:40 – Pizza, Drinks and Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **RSVP now to save your seat!**

We start games every 15 mins so do not worry if you are late. We mostly play in the English language as it is the language most people are comfortable with. We usually bring games with us but you are welcome to bring your own. Due to corona rules in Berlin (for more info: https://www.berlin.de/corona/en/measures/), please make sure to follow the rules on the page.

English is below In kurz & authentisch & unseriöser Künstler:) inneres und dann äußeres Fotoauge trainieren und Spaß dran haben. Wahrnehmung, Fotografie, Streetfood, Walk & beste U-Bahn :) Dazwischen Berlin in urban, lebendig, divers, dreckig, wunderschön, direkt im Kiezleben, mind. 1 Späti-Getränk, viele Reize und immer wieder ein Fokus. Dein Fokus. Wirst ihn immer wieder neu, anders, vertiefend für dich kennen lernen. Zwischen Ostkreuz bis Markthalle 9 wird unser Spielplatz sein. Ich freu mich darauf :) ausführlich, seriös: Dieser Street Walk verbindet urbane Erfahrung, Wahrnehmung und Fotografie in Berlin. Wir bewegen uns bewusst abseits klassischer Touristenrouten durch Friedrichshain, Kreuzberg und die Übergänge dazwischen. Straßenleben, Menschen, Bewegung und Streetfood gehören dabei genauso dazu wie das Fotografieren selbst. Dieses Format versteht sich weniger als klassische Fototour und mehr als urbane Erfahrung zwischen Wahrnehmung, Stadtgefühl und Fotografie. Die Kamera dient dabei nicht nur zum Festhalten von Motiven, sondern als Werkzeug, um bewusster zu sehen und Momente anders wahrzunehmen. Wer Lust hat auf schnelle Touristenbilder oder reine Technikvermittlung, wird hier wahrscheinlich nicht ganz glücklich. Wer dagegen neugierig darauf ist, wie stark Wahrnehmung, Aufmerksamkeit und Atmosphäre beeinflussen, welche Bilder entstehen und welche Erinnerungen bleiben, dürfte hier genau richtig sein. Das Format richtet sich an fotointeressierte Menschen, an Menschen ausm Kiez genauso wie auch Touris, die Berlin mal anders erleben wollen. Nicht als klassische Tour, sondern näher dran. Manche kommen fürs Fotoauge, manche für die Atmosphäre, manche einfach, um die Stadt (wieder) bewusster wahrzunehmen. Ich komme aus der Wahrnehmungspsychologie mit meiner Leidenschaft für Fotografie und verbinde diesen Blick mit urbanem Erleben. Und klar, auch der Gang zum Späti darf dabei nicht fehlen. Die ersten Walks sind Teil einer Beta Phase, in der ich gemeinsame Street Experiences auch ausserhalb von Teamevents ausprobieren möchte. Damit dieses Format in dieser Form möglich bleibt und sich entwickeln kann, liegt die Spendenempfehlung ab 20€. Bring Neugier, Kamera und/oder Smartphone für deine Wahrnehmung mit. Der Rest passiert unterwegs. Ich freue mich auf euch und auf die ersten gemeinsamen Walks diesen Sommer. This street walk combines urban exploration, perception and photography in Berlin. We make a conscious effort to stay away from the usual tourist routes, exploring Friedrichshain, Kreuzberg and the areas in between. Street life, people, movement and street food are just as much a part of the experience as the photography itself. This format is less of a traditional photography tour and more of an urban experience that blends perception, a sense of the city and photography. The camera serves not only to capture subjects, but as a tool to see more consciously and perceive moments differently. Those looking for quick tourist snaps or purely technical instruction are unlikely to be entirely satisfied here. On the other hand, anyone curious about how strongly perception, attention and atmosphere influence which images are created and which memories remain is likely to be in exactly the right place here. The format is aimed at people interested in photography, at Berliners from the neighbourhood as well as those who want to experience Berlin in a different way. Not as a traditional tour, but something more intimate. Some come for the photographic eye, some for the atmosphere, and some simply to perceive the city more consciously again. I come from a background in perceptual psychology with a passion for photography, and I combine this perspective with urban experiences. The first walks are part of a beta phase, during which I’d like to try out shared street experiences outside of team events as well. To ensure this format can continue in its current form, the suggested donation is from €20. Bring along your curiosity, a camera or a smartphone to capture your experiences. The rest will happen as we go. I look forward to seeing you all and to our first walks together this summer. Pierre

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
