C & C++

📢 Main event starts at 18:30 CET ✨ **Robert Schimkowitsch**'s test run for his presentation at ACCU on Sea! In this talk, we explore combining template techniques with std::variant. The result? Extensible code with less boilerplate. We cover the basics of the subject area, then introduce an example inspired by my own work experience. As we dive into some key code snippets essential to the overall design, we identify problems, then figure out how to solve them. On this journey, we learn about breaking dependencies, ergonomic use of distinct data types and replacing duplicate code with a single implementation. We look at template instantiations to visualize and understand both the compile-time and run-time aspects of our code. Finally, we evaluate the code design impact of our changes, what benefits they gave us, and what alternative options we could have used instead. After this talk, you will have a firm grasp on techniques that make std::variant even more useful in practice. This will give you more options for your next application subsystem design. You do not need prior knowledge of either std::variant or writing template code. 🪙 We appreciate any **voluntary donations** on-site. ⏱️ Arrive early for pre-socializing—simple snacks and drinks will be provided. 🍕 After the event, we will relocate to a pizzeria (at your own expense).

Monday 8th June 7-10PM ## Point of View It’s the bedrock of every relationship. You state your point of view, and your partner says theirs. Sounds easy, right? But how often are scenes derailed because the actors don’t hold onto their points of view or mindlessly add unnecessary details that throw the scene off course? Recognizing, maintaining, and evolving a point of view creates confident and exciting scenes. Tuedays 9th June 7-10PM ## Get in Focus What are you focused on when you begin a scene? What great offers are you missing because you’re building a story instead of a relationship? Learn how paying attention to your heart and breath leads to strong scenes and surprising dynamics.

PCE - "Philosophic Conversation in English" is a discussion event in English language which focuses on psychology, philosophy, self-consciousness and self-realization. The conversation is based on inclusive discussion rules. We will meet at at a restaurant where we will have a private room exclusively reserved for our event. At the beginning we will choose the two topics to discuss. Everybody can suggest a topic. Afterwards we will vote what topics to discuss. The person who suggests a winning topic will start the discussion by explaining his/her idea. Afterwards everybody gets his/her chance to make a statement. But you can also decide to remain silent and only listen, if you prefer that. We have a time limit for statements, so that everybody has enough time to speak. It is not allowed to interrupt somebody who is speaking. After a statement everybody can ask a question and the speaker will answer. After the first part there will be a 15 minutes break before we start the second part. Everybody is welcome to our event: We are interested in your thoughts and opinions! It is no problem if you arrive late and you can also leave whenever you want. Please don't bring pets to this event because the room is usually very crowded. Please make sure to register for the event to secure your seat! Please check out last event's topics via this link: [http://pce-topic.project-website.org](http://pce-topic.project-website.org/)

Single class: €28 / student €22 **This is for you if:** * You've tried tango once and want to go deeper * You've always wanted to learn but never knew where to start * You want a real foundation, not just a one-off workshop Spots are limited - this is a small group, so everyone gets proper attention. Drop a message here or reply directly to reserve your spot. 🙏

We are pleased to welcome **Eva Flonner** from UNIQA Insurance Group to present an R package for health insurance. Join us to explore how R can be put to work in actuarial practice, from data to modeling to simulation. As we promote gender diversity and inclusion in the R community, all genders and skill levels in R are welcome! **ℹ️ Abstract** **HePriceR** is an R package for health insurance pricing that provides a framework for modeling expected claims and their uncertainty. The package consolidates classical actuarial approaches with modern statistical modeling, enabling transparent, reproducible, and extensible actuarial workflows. The core focus of HePriceR lies in the estimation of expected claims and their uncertainty. It implements multiple methodological approaches, including the Rusam method for expected claims, as well as comprehensive frequency–severity modeling. The package further provides technical implementations for common product design features, such as deductibles, sublimits, and benefit caps, ensuring that modeled claim distributions align with contractual reality. From a software design perspective, HePriceR relies on a structured system of S3 classes and methods, including dedicated hpr_pricing_data objects and corresponding fit objects. This design enables consistent handling of data, fitted models, diagnostics, and downstream simulation. On top of the fitted models, the package offers Monte Carlo simulation capabilities. Overall, HePriceR provides a cohesive actuarial toolkit that bridges actuarial methodology and statistical modeling, supporting both daily operations and advanced analytical use cases. This package is based on joint work with Herr Kompott. **🗺️ Location** TU Wien Freihaus Wiedner Hauptstraße 8-10, 1040 Vienna ([map](https://maps.app.goo.gl/N8PSCZfdi97KirFY6)) Exact room to be announced soon.

Hi Deep Learners, We are happy to announce one more Vienna Deep Learning Meetup before the summer break: on **June 10** at ÖBB. We will again have two talks: Agentic AI in Production and Exploratory Causal Inference. \*\*\* **Agenda:** * 18:15 Arrival * 18:30 **Introduction** by the meetup organizers * **Welcome** by the host: ÖBB * 18:45 **Talk 1: Agentic AI Systems in Production: Best Practices, Challenges & Lessons Learned** by Hilda Kosorus (*Onefold AI*) * 19:30 **Announcements** * **Networking Break** * 20:00 **Talk 2:** **Scaling Empiricism in Artificial Causal Inference** by Riccardo Cadei *(ISTA)* * 20:30 **Networking** * \~21:30 **Wrap up & End** \*\*\* **Talk Details:** \-\-\-\-\-\-\-\-\-\-\-\-\-\- **Talk 1:** **Agentic AI Systems in Production: Best Practices, Challenges & Lessons Learned** Building agentic AI systems that work in production is harder than the demos suggest. Real users, real data, and real edge cases surface challenges that don't show up in most tutorials. We must consider orchestration trade-offs, observability gaps, evaluation strategy, latency and cost realities. There's constant tension between giving agents autonomy and keeping them under control. In this talk, we share what we've learned shipping agentic systems end-to-end. We'll walk through how our architectures evolved and the trade-offs behind each shift, and we'll be honest about which frameworks — such as LangGraph, LangChain, Langfuse — earned their place in our stack. Expect architecture diagrams and the patterns we now apply to lead our custom projects to success. **About the speaker:** We are Onefold AI — Tobi, Csenge, and Hilda. We combine deep LLM engineering with a research foundation, years of data science work, and multiple agentic systems shipped end-to-end into production. Our recent projects span compliance and audit automation, multi-agent workspaces for food scientists, and our own product development — all building on the hard-won lessons we'll share in this session. **Talk 2:** **Scaling Empiricism in Artificial Causal Inference** Randomized trials are the gold standard of empirical science, yet their analysis still hinges on hand-crafted hypotheses: the investigator has to decide upfront what to measure and whom to compare, often anchoring on familiar narratives. A paradigm shift is now within reach: modern trials measure more, and representation learning gives us the tools to scale the reading accordingly. In this talk, I will present two algorithms I developed to bridge this richer measurement to causal claims, e.g., scientific discoveries or policy guidelines. Neural Effect Search (NES) identifies the latent effects of a treatment from unstructured outcomes. Neural EXposure Interaction Search (NEXIS) identifies an interpretable and prescriptive characterization of effect heterogeneity. I will illustrate both through real-world deployments in experimental ecology and development economics. **About the speaker:** Riccardo Cadei is an ELLIS PhD student at ISTA with a growing record of foundational, methodological, and applied contributions to Causal Inference and AI for Science. He actively collaborates with biologists, neuroscientists, economists, and public-health researchers, translating his vision of Artificial Causal Inference into concrete scientific workflows. We are looking forward to welcoming you at our last meetup before summer! Your VDLM organizer team

Hello everyone! It’s been long in the making, but finally all pieces have fallen into place and we’re beyond excited to announce a very special edition of our meetup on Tuesday, June 9th: **Shitty Robots & Weird Tools - with Mario & Armin**. These two speakers probably don’t even need an introduction in this community as it’s largely due to them and their buddy Peter that Austria/Vienna has become a well-known spot on the AI Engineering world map. Still, if you don’t know them yet, find the details about them below. **Mario** will kick off the meetup with a talk about a recent pet project of his, the **“Shitty Robot”**. Then **Armin** will talk about **“Weird Tools”** for coding agents. And we’ll make sure there will be room for plenty of questions from the audience. This announcement is very short-notice, as the **meetup is in just two days**, but we hope that despite that you'll be able to join us and listen in person to Mario and Armin's uniquely interesting takes on AI, before the World Cup and the summer months make such gatherings effectively impossible. Special thanks to **SQUER**, who have jumped in and generously offered us their office in the **9th district** to host this special event. Join us for an unforgettable evening with the **Austrian AI Engineering avant-garde**! \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Speakers \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- For the folks who don't know these two already 😉… * **Mario Zechner** (**@badlogicgames**) is the creator of Pi, a minimalist, self-modifying AI coding agent now stewarded by the startup Earendil, where he's a stakeholder and team member. Before AI, he built the popular cross-platform Java game framework libGDX and spent years on the animation tool Spine. Refreshingly blunt about the industry, Mario calls permission popups "security theater," warns about "token addiction," and tells engineers to slow down and treat agents as surgical tools. Blog: [https://mariozechner.at/](https://mariozechner.at/) * **Armin Ronacher** (**@mitsuhiko**) co-founded Earendil to build AI developer tooling, after a decade at Sentry where he was a very early engineer and rose to VP of Platform. He's best known as the creator of Flask, the Python microframework that famously began as a 2010 April Fool's joke, and of the Jinja template engine, alongside a long line of Pallets and Rust projects. A prolific blogger and frequent speaker, he's openly skeptical of AI hype while building squarely within it.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
