KI ausprobieren kostet Zeit. Und meistens läuft es zuerst schief. Genau dafür haben wir unsere Learning Fridays: ein geschützter Rahmen, in dem Gepardec-Teams echte KI-Technologien testen – ohne Kundendruck, ohne Deadline. Was funktioniert. Was nicht. Und warum. Am 29. Mai teilen wir das offen. Was du konkret mitnimmst 👉 Du sparst dir die Umwege, die wir bereits gegangen sind: 🔬 AI-gestützte Systemanalyse – Welche LLM-Tools für Enterprise-Kontexte taugen, welche nicht – und was MCP wirklich bringt. ⚙️ AI-Assisted Code Migration – Wo Konveyor AI bei WildFly→Quarkus-Migrationen wirklich hilft und wo du trotzdem manuell ran musst. 🦙 Tune das Llama – Was beim Fine-Tuning eines lokalen LLMs schiefgeht, bevor es funktioniert – Datenmenge, Konfiguration, Evaluierung. Für wen ist das relevant? 👉 Für alle, die KI in ihrer Softwareentwicklung einsetzen wollen – aber keine Zeit haben, bei Null anzufangen. ────────────────────────── 08:30 → Frühstück (Wien & Linz) 09:15 → Unsere Haltung zu KI (ab hier auch Remote) 09:30 → AI-gestützte Systemanalyse 10:15 → AI-Assisted Code Migration 11:15 → Tune das Llama 12:00 → Unser Angebot: Gemeinsames KI-Projekt 12:15 → Networking 📍 Vor Ort: Frühstück inklusive 💻 Remote: Google Meet 👉 Anmeldung bis 26.5.: https://www.gepardec.com/ki-learning-friday/ #KI #LLM #Quarkus #MCP #FineTuning #Gepardec #SoftwareEntwicklung #KonveyorAI

Dear Data Enthusiasts, Join us again on **29th of May** at **A1** to learn about the psychological implications on employees when transforming the data landscape of an organization. In addition, we will finally have a talk about the open source framework Metaxy and how it can help to cut costs of multimodal AI pipelines. A big thanks goes to our co-organizers from the A1 Telekom and our sponsor Cloudera! **A Psychological Autopsy of a Data Transformation** *Dávid Farkas* Five years ago, a small European university decided to build and implement a data strategy from scratch. Greenfield in the truest sense: data governance was an unheard term and in practice it meant local Excel files duplicated across inboxes; "the database" usually referred to whichever spreadsheet someone had emailed most recently. Over four years, we designed and rolled out new systems, established governance structures, hired a team, and delivered real wins. We also watched a significant portion of the work get undone in months once leadership changed. This talk is a psychological autopsy of that transformation — what was planned, what worked, what quietly collapsed, and why. Universities are an unusually honest laboratory for studying data initiatives: decentralized power, competing stakeholder logics, weak formal hierarchies, and ambiguous success metrics make every human dysfunction that exists in corporate environments more visible. Drawing on behavioural science and nearly five years leading this initiative, I'll walk through the recurring failure patterns I see across data and AI projects more broadly — algorithm aversion, NIH syndrome, the gap between executive sponsorship and operational ownership, and the under-recognised role of organisational identity in determining which systems survive a leadership change. The argument is not that technology doesn't matter — it's that the human substrate determines whether any of it sticks. Borrowing Kranzberg: technology is never neutral, and neither are the people implementing it. **Dávid Farkas** is a research psychologist (PhD) and data scientist based in Budapest. He co-founded Principle Zero, which helps companies, NGOs, and researchers take on complex challenges in data strategy, digital and AI transformation, research, product development, and science communication. We bring behavioural science to problems most consultancies treat as purely technical, focusing on the human and organisational factors that determine whether ambitious projects survive contact with reality. Previously he led data science and digitalisation at MOME Budapest, with earlier industry experience applying machine learning. **Optimizing Multimodal AI Pipelines with Metaxy** *Georg Heiler, Hernan Picatto* The AI era has caused a fundamental shift in computing, moving us toward complex multimodal pipelines. However, these new systems are often incredibly wasteful. Right now, small changes to an input can trigger massive recomputations across very expensive processing steps. In this talk, we will explore Metaxy, an open source Python framework built to solve this exact problem. Metaxy provides sample level metadata versioning and acts as the universal glue for incremental data pipelines. We will discuss how its field level provenance allows your pipeline to only recompute what actually changed. If you update an audio file, for example, Metaxy knows to skip downstream face recognition steps that only rely on video. Whether you are a startup stretching your compute budget, an enterprise scaling ML infrastructure, or a researcher in academia, you will learn how to use Metaxy to iterate faster, cut cloud costs, and build highly efficient AI workflows. **Georg Heiler** is a co-founder @Jubust and a Senior data expert at Magenta as well as a ML-ops engineer at ASCII. He is solving challenges with data. His interests include geospatial graphs and time series. Georg transitions the data platform of Magenta to the cloud and is handling large scale multi-modal ML-ops challenges at ASCII. **Hernan Picatto** is a Computer Science PhD candidate at the Vienna University of Technology researching firm-level supply chains and corporate networks using NLP and Common Crawl data. Formerly an engineer at JPMorgan Chase and ZhiZhouKeji, he holds an MA from UCSD. His broad interests span big data, visualization, and time series causality. 🎤🎤 Open Mic We are going to open up the stage after the talks for community announcements.

Hi Running fellows, Whether you’re a walker, new to running, a semi-pro, a marathonist or a sprint star - if you want to start your weekend in an active way and enjoy the outdoors in lovely surroundings with a fun, international and multilingual group of people, you are welcome to join us! Every Saturday at 9:30 am, we meet, we run, in the magnificent Schönbrunn park, and then we go for breakfast. Want to discuss politics or the best recipes for banana pancakes? Not a problem. Not feeling social? Tune out with your earbuds - we can talk over breakfast. We are casual. You can be too. What to expect: Start by meeting Adrian, Ali, Liz, Paul and Sonia on-time at 9:30am outside the Schönbrunn U-Bahn stop (exit Grünbergstraße). (Coordinates: 48.1858130, 16.3200640) From there, we walk to the side park entrance where the “running” part begins. The important thing is that you run at your own pace. Typically, small groups of people will run at the same pace as you, so you never have to walk/run alone :) We finish one hour later, at about 10:40am, reconvening just inside the Hietzinger Tor exit. (Coordinates: 48.1858825, 16.3032647). From there, we’re off to breakfast! Breakfast Details: Anker bakery opposite the U4 Hietzing station and depending on the weather, grab something for a picnic in Schönbrunn park, or hang out in the bakery. If you missed us earlier, you can always go there around 10:45. We are a fun group of runners who don’t take things too seriously. We meet, chat, RUN, stretch, chat, EAT and we hang out over a beer every now and then. It's that easy. Please join us for breakfast after the run! The more the merrier. Typically we are 10-30 people, as not everyone who comes signs up on meetup. Important disclaimer: Please only run as much as you feel you can, considering the temperature, weather conditions, your own fitness etc... run and walk at your own pace as the organizers do not assume any liability for any injuries or health issues. Sonia, Adrian, Ali, Paul and Liz
