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!**

Der Stammtisch beginnt um 19:00 Uhr der **Vortrag um 19:30**. **Fakten, Fakes & Emotionen** Fakten zählen – oder nicht? In einer Welt der Informationsflut entscheiden immer weniger Argumente, sondern pure Emotionen. Fake News und deren Verbreiter:innen nutzen gezielt unsere Gefühle, um Desinformation viral zu pushen, attackieren mit voller Absicht Demokratie und gesellschaftlichen Zusammenhalt. Ein exzellentes Negativ-Beispiel erleben wir leider auch in den USA. Warum glauben Menschen lieber Falschmeldungen als Wissenschaft oder belegbaren Fakten? Warum ist niemand vor Fakes sicher? Falls wieder einmal die Desinformationswellen erdrückend über uns zusammenbrechen, können professionelle Faktenchecker:innen oft mit Fakten, Methoden und Hilfe zur Selbsthilfe unterstützen - wie zum Beispiel auch die Artikel des rein durch Crowdfunding finanzierten Anti-Fake-News-Blogs Volksverpetzer, der auf allen großen SoMe-Plattformen und mit eigener App präsent ist. **Marcello V. Orlik:** Als BWL-Dino mit starkem Wirtschafts-Background, hätte sich Marcello V. Orlik auch noch vor 10 Jahren nicht vorstellen können, dass nicht nur Logik, die Klimakatastrophe und wissenschaftliche Fakten mit aller Leidenschaft verteidigt werden müssen. sondern tatsächlich auch eine signifikante Portion Aufklärung, Journalismus und Politik für ihn im Alltag unabdingbar werden - als Relations Manager beim Volksverpetzer. **Forma** Das Edutainment-Format "Skeptics in the Pub" kommt ursprünglich aus dem UK und verbindet unterhaltsame wissenschaftliche Vorträge mit Diskussion und Socializing in entspannter Atmosphäre Seit einigen Jahren gibt es auch im deutschsprachigen Raum regelmäßige Veranstaltungsreihen u.a. in Köln, Wien und jetzt auch in Berlin

🕢 Doors open at 18:30 and sessions start at 19:00. Freestyle vocal workout at and play session. €8-20 😌 Flow is a state of being… an experience when you allow yourself to be 100% fully engaged in the present moment in a feedback loop between clarity and satisfaction. It is an undeniable sensation where things seem to be more effortless, pleasurable, in sync, and you can easily sense a connection with something greater than yourself; this is what we will create…: • a connected and mindful meditation where it is possible to blissfully surf the cutting edge of the present moment together… • a game where it’s possible to feel excited and calm in the same moment, and everyone can win as much as they like… Scott Bolden, founder of Das Baumhaus Berlin will share some very easy, practical and effective methods developed during the last 12 years of facilitating the “Improvisational Groove Orchestra” (I.G.O.) improv vocal jam sessions. Within 20 minutes participants learn to use the common sound space to create resonance in the form of improvisational music where it is quite common to experience some real flow moments… It is very easy to participate, no musical talent or training is required so anyone is welcome to join. All of the session is done with eyes closed to avoid visual distractions and keep focus on the co-created sound space. During these sessions we will also have short breaks for feedback and refreshment. Important – Please be on time. It is very important to understand the methodology and warm up in the group before joining in! 🎤 @21:00 - Freestyle vocal workshop and practice session. €8-15 Have you ever wanted to learn how to do freestyle vocalizations?

Let’s meet and share discussion of the James Baldwin short story collection, Going to Meet The Man.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

Join us for Sharp Objects by Gillian Flynn! Fresh from a brief stay at a psych hospital, reporter Camille Preaker faces a troubling assignment: she must return to her tiny hometown to cover the unsolved murder of a preteen girl and the disappearance of another. For years, Camille has hardly spoken to her neurotic, hypochondriac mother or to the half-sister she barely knows: a beautiful thirteen-year-old with an eerie grip on the town. Now, installed in her old bedroom in her family's Victorian mansion, Camille finds herself identifying with the young victims—a bit too strongly. Dogged by her own demons, she must unravel the psychological puzzle of her own past if she wants to get the story-and survive this homecoming.
