C++26, AI & GPU Computing | Meeting C++ Warm-Up

The next **Berlin C++ Meetup** hosted by thinkcell takes place on **Wednesday, November 25**, the evening before **Meeting C++** — the perfect warm-up for a conference full of ideas, conversation, and connection. Join us for an evening with the Berlin C++ community, this time as a warmup to Meeting C++! 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. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📅 **Date & Time:** Wednesday, November 25, 2026 – 18:30–22:00 📍 **Location:** Circuit (w3.hub) - Möckernstraße 120 10963 Berlin 🕒 **Agenda** 18:30 – Doors open 19:15 – Talks + Q&A 20:45 – Food, Drinks and Networking 22:00 – Closing doors \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ## **Talk** ### **Speaker**: Sandor Dargo **Bio:** Sandor Dargo is a Senior Software Engineer at Spotify, where he works with C++. He cares about writing code that stays maintainable long after it's shipped, and about helping other engineers do the same. He shares what he learns on his blog, [sandordargo.com](https://www.sandordargo.com/), in conference talks, and in his books, including The C++ Interview Book. Outside of work, he enjoys baking, travelling to new places, and spending time with his wife and two children. **Title: The Real Story of C++26: Beyond the Headline Features** **Description:** C++26 is often defined by its headline features — reflection, contracts, and senders/receivers. But those don’t tell the whole story. In this talk, we’ll look beyond the headlines to explore the changes that more accurately reflect where C++ is heading. While less visible, these features address long-standing pain points, improve consistency, and quietly reshape everyday programming in C++. We'll examine the continued expansion of constexpr, including the ability to throw exceptions at compile time, and what it means for the boundary between compile-time and runtime. We'll also discuss the evolving model of erroneous behavior and indeterminate values, making it more explicit what constitutes incorrect code — and how implementations can reason about it. Safety is also becoming a stronger focus in the standard library. With the introduction of library hardening, C++26 takes steps toward making incorrect usage easier to detect and harder to ignore, without sacrificing performance. Along the way, we'll look at improvements to function wrappers with std::function_ref and std::copyable_function , enhancements to structured bindings, and the growing capabilities of std::format . We'll also cover pack indexing and its impact on template expressiveness, as well as the ongoing expansion of the freestanding library. Rather than focusing on individual features in isolation, this talk connects them into a broader narrative: the real direction of C++26 — toward greater clarity, expressiveness, and safety in everyday code. ## **Lightning Talks** ### **Speaker**: Adi Seshaditya **Bio:** Background in simulations; worked on projects related to applied ML for industrial systems (Consortium Projects Germany) as Data Scientist **Title: AI for Simulations** **Description:** LLM agents can now write OpenFOAM case files from a single natural-language sentence, but a case that runs is not necessarily a case that is right. We examine how AutoFOAMagent (Neelan & Seshaditya, arXiv:2608.00003) checks its own output: constrained generation, deterministic solver selection, execution-based scoring, a held-out benchmark, and regression auditing of the model itself. It then covers where that validation still falls short and how the same ideas can carry over to Digital Twin work. ### **Speaker**: Ankit Mittal **Bio:** Ankit Mittal is a Senior Real-Time Software Developer at Lake Fusion Technologies in Berlin. He has over 13 years of experience in C++, GPU computing, and numerical software across fluid simulation, automotive radar, and real-time sensor processing. He works on Brae, an open-source GPU solver for OpenFOAM cases. **Title: Keeping the Solver on the GPU with C++ and CUDA** **Description:** A dot product returns one number. What does it cost when a C++ solver has to wait for that number on every iteration? Using Brae’s pressure solver as a case study, I’ll walk through two versions of the same iterative solve. In the first, a C++ loop launches GPU work and waits for dot-product results. In the second, a CUDA Graph keeps those results on the GPU and lets the GPU decide whether to run another iteration. With short code excerpts, I’ll show how that changes which parts of the C++ code manage buffers, launch work, and check for convergence. You’ll see how to spot the same kind of synchronization in your own GPU code, even when the amount of data being transferred is just one number. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **RSVP now to save your seat!**

Portrait Drawing on Sunday Afternoon

This group is for everyone who is interested in drawing portraits! For me, drawing has been a wonderful way to gain a new perspective on the world and the people within it. Whether you are just starting out or have been drawing for ages — all levels are welcome :) How it works: 1\. We meet at The Castle pub in Mitte and do short sittings of 15 minutes for each other\. The first sitting is divided into 3 warm\-up sketches\, 5 minutes each\. 2\. Before we start\, everybody writes their name on a blank card \(provided by the organizer\); these cards are then used to randomly pick the model every 15 minutes\. 3\. Usually we do 8 sittings\, with a 15\-minute break in the middle \(so after 4 sittings\, or 1 hour\)\. -> The participation is free, but it is expected that everybody orders something from the bar to support the lovely location. Get out your pencils and let's start! Please bring your own art supplies!

INNOQ Technology Day Meetup | Coding Agents & Outcome-Driven Architecture

Am 12. November findet der **[INNOQ Technology Day](https://technologyday.innoq.com/)** statt, unsere kostenfreie Online-Konferenz rund um Softwarearchitektur, -entwicklung und digitale Produkte. Von 9 bis 18 Uhr stehen zwei Keynotes und 18 Vorträge in drei parallelen Tracks auf dem Programm. **Im Anschluss an das Tagesprogramm** laden wir Euch zu uns ins INNOQ-Büro nach Berlin ein. Dort greifen wir zwei Themen vom Tag noch einmal auf. Danach habt Ihr bei Snacks und Getränken Zeit, Euch mit den Speakern und den anderen Teilnehmenden auszutauschen. Johannes Rave und Aminata Sidibe bringen ihre Sessions vom Tag als Kurzvortrag mit und gehen dabei tiefer ins Thema. Wer online nicht dabei war, kann hier noch einmal reinhören und wer die Sessions tagsüber schon gesehen hat, bringt gerne Fragen mit und vertieft die Themen mit uns vor Ort. **Ablauf:** **18:30 \|** Doors open **19:00 \|** Start der Kurzvorträge danach Diskussion & Networking **Zur Anmeldung:** Der Abend ist offen für alle, **eine Teilnahme am Technology Day ist keine Voraussetzung**. Meldet Euch trotzdem hier über Meetup an, auch wenn Ihr tagsüber schon dabei wart. Dann wissen wir, mit wie vielen Leuten wir planen können. **+++ Die Talks +++** **No Constrain, No Gain: Struktur für den Agent, Klarheit für den Menschen, Flexibilität für das Unternehmen** Johannes Rave, INNOQ AI Coding Agents sind bemerkenswert gut darin, Code zu erzeugen. Ob dieser Code die tatsächlichen Anforderungen des Unternehmens widerspiegelt und ob er auch sechs Monate später noch sinnvoll ist, ist eine ganz andere Frage. Die Versuchung ist groß, das als Prompting-Problem zu behandeln und dem Agenten mehr Kontext, bessere Anweisungen und klarere Ziele zu geben. Ein oft übersehener Hebel ist dagegen die Architektur. Wenn die Domänenlogik ihren eigenen, klar abgegrenzten Platz bekommt, getrennt von der technischen Infrastruktur um sie herum, passiert etwas Interessantes: Der Agent bleibt fokussiert, Menschen können tatsächlich prüfen, was wichtig ist, und das Ganze bleibt änderbar, ohne dass alles neu geschrieben werden muss. Johannes Rave stellt einen Ansatz vor, wie man dorthin kommt und wie ein paar gut platzierte Einschränkungen Freiheit schaffen. **Über Johannes:** *Johannes Rave ist Senior Consultant bei INNOQ. Er baut robuste LLM-gestützte Produkte und verteilte Websysteme – mit Fokus auf RAG, semantische Suche und produktionsreife Umsetzung. Brückenbauer zwischen UX, Architektur und Betrieb.* **Mehr Wert, weniger Code: Warum gute Architektur bei Nutzerbedürfnissen beginnt** Aminata Sidibe, INNOQ Software zu entwickeln war noch nie so einfach wie heute, und generative KI beschleunigt das zusätzlich. Was nützt uns diese Geschwindigkeit aber, wenn wir nicht wissen, ob wir das richtige Problem lösen? In vielen Projekten steckt viel Energie im Output: Roadmaps, Tickets, Velocity, Releases. Dabei fehlt manchmal das gemeinsame Bild davon, für wen wir eigentlich entwickeln und welchen Nutzen ein Feature haben soll. Aminata Sidibe zeigt, wie Outcome-Driven Architecture Teams hilft, sich auf das Wesentliche zu konzentrieren. **Über Aminata:** *Aminata Sidibe ist Principal Consultant bei INNOQ und verfügt über langjährige Erfahrung in der Umsetzung digitaler Produkte verschiedenster Größenordnungen. Ihre Expertise liegt in der Mensch-Maschine-Interaktion sowie der Zusammenarbeit in Teams. Aktuell fokussiert sie sich auf die Integration Künstlicher Intelligenz im Bereich der digitalen Produktentwicklung. Zu ihren zentralen Aufgaben gehören neben User Experience und Zusammenarbeit auch die technologische Weiterentwicklung und der Umgang mit kulturellem Wandel in Unternehmen.* **+++ INNOQ Technology Day +++** Zum Technology Day am 12. November könnt Ihr Euch übrigens noch kostenfrei anmelden. Das komplette Programm mit allen Sessions findet Ihr [hier](https://technologyday.innoq.com/). 👉 Wer es abends nicht zu uns ins Büro schafft, kann sich Johannes’ und Aminatas Vorträge auch tagsüber online ansehen: * ["No Constrain, No Gain"](https://technologyday.innoq.com/programm/no-constrain-no-gain), Johannes Rave, **14:00 Uhr** * ["Mehr Wert, weniger Code: Warum gute Architektur bei Nutzerbedürfnissen beginnt"](https://technologyday.innoq.com/programm/mehr-wert-weniger-code-warum-gute-architektur-bei-nutzerbeduerfnissen-beginnt), Aminata Sidibe, **15:00 Uhr** Wir freuen uns auf Euch!

Beyond the Career Break: Creating Better Opportunities for Mothers

**An afternoon of insights, practical resources and networking in Berlin** Whether you work in education, vocational training, women's support, employment services or community development, a mother looking to reenter the job market, or simply care about creating better opportunities for mothers - you are welcome. What makes it difficult for mothers to return to work, access vocational training or develop the skills they need for today's job market? For many mothers, especially those facing challenging circumstances, the barriers go beyond motivation. Limited time, caring responsibilities, gaps in digital skills, lack of confidence and learning opportunities that do not fit their realities can make taking the next step difficult. Join us for an afternoon in Berlin to explore these challenges and discover practical ways to make learning, skills development and employment more accessible to mothers. **What can you expect?** · **Understanding the challenges:** Insights gathered from mothers and organisations working with them in Germany, Greece, Bulgaria and Türkiye. · **Practical resources:** Discover learning materials and approaches designed to support mothers in developing digital skills and improving their employability. · **Inclusive VET:** Explore how vocational education and training can better respond to mothers' needs and circumstances. · **Exchange and networking:** Meet people and organisations interested in inclusive education, women's empowerment and better employment opportunities for mothers. The event will bring together project findings, practical outputs and perspectives from people working in the field. There will also be time to connect, exchange experiences and explore opportunities for collaboration. **In partnership with RIIK Berlin** BRIDGE4MOTHERS is an Erasmus+ project of Impact Grid e.V.
