We are back in the c-base! Do you already run NixOS and want to talk to other people or want an introductory session with some NixOS users. Just bring your machine! Usually there are no topics, we just sit in front of our computers, talk about stuff, debug some problems or review some PRs on nixpkgs. There are drinks usually available from the c-base bar. If you can't find us. just ask around or ask in irc (#krebs on hackint)

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!**

Women Techmakers Berlin and SPICED Academy are joining forces to host an evening focused on both building *efficient AI systems* and navigating the real challenges of building a *career in tech*—beyond just learning technical skills. ## Talks Talk 1: Confidence Beyond Skills - What Really Holds Women Back in Tech Careers - by Marina Matveevskaia Many women in tech keep investing in new courses, skills, and certifications, yet still feel stuck or “not ready enough” to take the next career step. In this talk, we will look beyond technical competence and explore the less visible factors that often shape career growth much more strongly — such as self-trust, fear of visibility, internalized expectations, and the emotional impact of burnout or layoffs. I will share common patterns I see in highly capable women and why “just improving skills” is often not the real barrier. Participants will leave with new perspectives and simple reflection tools to better understand what is holding them back and how to move forward in a more sustainable and aligned way. Talk 2: Efficient Agentic Systems - by Jane Waithira Let Classical ML Do the Heavy Lifting, Let Agents Do the Thinking There’s a temptation to throw an LLM at every problem—but the most effective systems take a different approach. This talk explores how to combine deterministic, classical machine learning for predictable tasks with LLM-powered agents for reasoning and decision-making—so you can build systems that are fast, cost-effective, and reliable. ## Speakers **Jane Waithira:** Jane Waithira is an innovative, solution-oriented developer working in AI/ML, currently at SAP in Germany, where she integrates applied AI and GenAI for SAP's own cloud infrastructure. With over five years of experience building production AI systems, Jane has established her skillset in practical applications of ML and GenAI. Her talk will provide attendees with a practical framework for building efficient agentic systems that combine deterministic classical ML with the flexibility of LLM-powered agents. [https://www.linkedin.com/in/waithira-macharia/](https://www.linkedin.com/in/waithira-macharia/) **Marina Matveevskaia:** Marina Matveevskaia is a Professional Identity and Transition Coach working primarily with women in tech and international professionals in Germany.

## Learn Go and NixOS deployments with large language models Hello, 世界! When used sensibly, language models can be tutors, too. For meetup #60 on Tuesday [May 26, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537727) we are really happy to have [Maxime](https://www.linkedin.com/in/plumps/) dive into Nix/NixOS with the help of language models. Nix is a functional package manager and its immutable traits enable robust, reproducable deployments of Go (and other) projects. The high level goals of Nix/NixOS are similar to other immutable Linux distributions, like [Silverblue](https://fedoraproject.org/silverblue/) or [Bazzite](https://bazzite.gg/). Becoming familiar with the Nix configuration language can be a challenge, but one that a well instructed tutor may help with. > Artificial intelligence techniques are increasingly used in education to enable personalized learning and intelligent tutoring [LLM Agents for Education: Advances and Applications](https://aclanthology.org/anthology-files/anthology-files/pdf/findings/2025.findings-emnlp.743.pdf) (11/2025) Why reproducible and immutable deployments play a role? [Justin Garrison](https://justingarrison.com/blog/state-of-immutable-linux/) says: > It’s 2026, if you’re not using something immutable (or at least reproducable) you’re doing more maintenance work than you should. [blog post recapping talk from [Southern California Linux Expo 23x](https://www.socallinuxexpo.org/scale/23x)], 03/2026, PASADENA, CA ### Schedule * 18:45 Doors open * 19:00 Welcome * 19:10 Dive into Nix/NixOS with LLMs * 19:50 Open discussion We’ll meet: * in person at [Basislager Leipzig](https://basislager.co), at [Peterssteinweg 14, 04107 Leipzig](https://maps.app.goo.gl/1fMkeDSPZ7Aauszh8) ([OSM](https://www.openstreetmap.org/node/3504864558)) * and online via [Google Meet](https://meet.google.com/poy-koue-spc) Join us to discuss robust Go deployments, language models as learning tools and more!

You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance. **Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.** We are excited to host a **BLISS x dida workshop** featuring **Lazar Obradović (Lead Data Scientist @ cognee.ai)**, who will guide us through an interactive session on Agentic AI. ​Title: Explainable Scientific Discovery with AI Memory: Hypothesis Generation and Validation with Cognee and Bayer 📅 Date: 27.05.2026 🕕 Time: 18:00 📍 Location: TU Berlin Marchstrasse 23 [Room 0.011] ​The session will last around 2 hours, followed by a networking session with dida and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! **​Abstract: Building "AI scientist"** systems that can reliably generate and evaluate research ideas remains effectively an open problem. While LLMs make hypothesis generation cheap, current systems still struggle to connect evidence across papers, domains, and mechanisms in a structured and reusable way. Evaluation is equally difficult, often relying on opaque “LLM-as-a-judge” methods that are hard to interpret or reproduce. We use Cognee to ingest scientific literature and construct a graph-based representation of papers, claims, and entities with associated vector embeddings. We then use this structure to select and organize the context used for hypothesis generation. Candidate hypotheses are evaluated using explicit graph- and vector-based metrics grounded in the underlying corpus. Initial evaluations by Bayer across targeted biomedical domains demonstrated that graph-based AI memory can reliably support scientific hypothesis generation and validation. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend. The event location will only be visible after your registration is confirmed by the host. Link: https://luma.com/1sre8dy7?utm_source=meetup** *** We are **BLISS e.V.**, Berlin’s AI community connecting like-minded individuals passionate about machine learning and data science. Our **BLISS Workshops** connect **students and young professionals with industry partners**, offering an inside look into **how machine learning is applied in real-world settings** \- from research and development to deployment\. ​We are **dida**, scientific engineers who believe that **reliable AI** should not be a **"black box".** That is why we prioritize transparency, mathematics, and code over hype.

This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process. Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production. **Speaker**: Oren Matar **Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing. **Talk 2: Interpreting and Communicating Statistical Models** **Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data. We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders. **Speaker**: Juan Orduz **Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks.
