**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.

Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or not so talented? Are you tired of insecure bros who only want to show off their skills? **Then [Lousy & Lazy Football](https://www.instagram.com/landlsc/) is the right thing for you!** We are a group of friendly people who just want to have a relaxed kick. All genders, ages (+18) and nationalities welcome. **Feel free to join the waitlist even if it seems long - sometimes we make the event larger and play on two pitches (24 players, four teams) or even three pitches (36 players, six teams), depending on demand.** Note: **We do not allow high-studded football boots during our sessions.** To avoid injuries, we only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/). Rules for lazy & lousy football 1. **Don’t be competitive** 2. **No hard tackling/sliding challenges** 3. **Support new players by giving them the time and space to play the ball** 4. **Don’t dribble past multiple players (trying to take on a player is fine but at no point should you be trying to dribble past multiple players).** 5. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.** 6. **Rotate the goalkeeper** 7. **Be a teamplayer** Waiting list: This meetup is for members of the Lousy & Lazy Sport Club. If you want to try out our lousy & lazy sport events, you can do a trial run (Probetraining).

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 5th floor 🕒 **Agenda** 18:30 – Doors open 19:00 – Talk + Q&A 20:40 – Pizza, Drinks and Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **RSVP now to save your seat!**

Ok everybody, it's 2026, and after taking a break for the holidays, games are starting up again as usual. We'll meet, have a beer, and play a round of cards against humanity. Laughs will be had, groans will be groaned, beer will go down the hatch. This event is public, and prior experience with the game is not required. You are not required to drink alcohol, but please note that we are crashing a bar (cash only), so a beverage purchase or two is appropriate and necessary for us to maintain their goodwill. See you there!

Please contact me on WhatsApp if you’d like to join our group, as this group will soon be deleted from Meetup. 017684589930 Thanks, Marco We play every Sunday—year-round—and are looking for a few players who are willing to join regularly. Average age is around 27-50. We play on grass using poles as goals, which allows us to adjust the field and goal size depending on the number of players. Please arrive on time, as we need to divide the teams. Game starts 11:30 sharp. Wir spielen jeden Sonntag - ganzjährig - und suchen nach ein paar Spielern, die sich vorstellen können, regelmäßig dazuzukommen. Alter im Schnitt ca. 27-50. Wir spielen auf Rasen mit Stangen als Toren, wodurch wir die Platz- und Torgrösse flexibel a die Anzahl der Spieler anpassen können. Bitte pünktlich da sein, weil wir die Mannschaften aufteilen müssen. Das Spiel beginnt pünktlich um 11:30 Uhr.

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** https://youtube.com/live/BltmWMH1zG0?feature=share
