**What is Innate Dance?** Innate Dance is a joyful approach to movement, which invites deeper embodiment and self-connection through butoh inspired movement, Noguchi Taiso exercises, the Seki Method, somatic attention and imagination. We shake it out, breaking up stuck energy held in the body, and explore new movement possibilities from a place of alignment and sensitivity. Thanks to our open awareness we can be surprised by lesser-known parts of ourselves and come to appreciate our innate wisdom in movement. Through exercises, explorations and improvisations we build trust in the body that knows how it would like to move and express itself, and when we follow our innate dance, it just feels good! There is also time and space to dance freely, to enjoy the music in your body and to let go! Ultimately, it's about feeling more 'in' our body and grounding joy. **When? Where? How much?** **Mondays 19:30-21:00** in Studio 2, Tanz\*Hotel, Zirkusgasse 35, 1020 Wien Try out € 16\,\- \| One class drop\-in € 21\,\- \| Student € 10\,\- \| 5 x class pass €95\,\- \| 1 x class pass for rest of semester € 224\,\- \(or €16/class\) **Who teaches the course?** Jess is a dancer and psychotherapist (humanistic and integrative), who loves shaping classes that offer the space to explore the many facets of being human. Sometimes this learning involves physically embodying non-humans like trees, fish and wind, so we can get out of our limited-human-thinking-mind and into the bigger wisdom available through imagination and our body. At other times it's about dancing textures, sensations or taking on the energy of parts of ourselves so we can know them better. Jess has danced all her life and has been exploring butoh dance for the past eleven years alongside her psychotherapeutic practice. She is co-author of *The Seki Method - Basics* (now available to buy online via website), is a Seki Method Facilitator, and was a 2024 student at the Im_Flieger Schule researching dance and healing.

Agenda (preliminary) 18:00 doors Open 18:20 welcome, doors closing soon 18:30 **Centralising and automating your API contracts using a schema registry** 19:30 Networking 20:00 **OpenJDK, the JCP and JUGs: contributing to Java to become a beyond senior expert** 21:00 networking Talk 1: **Centralising and automating your API contracts using a schema registry** No matter if REST or message-based, your APIs need to change. Describing the API using OpenAPI or some other specification language is good. But how to make sure all affected parties have the same version of the API spec and that spec changes don't happen before all API users are ready? Let's discover how schema registries can bring order and automation in this. We'll take a look at how you can use them with Java and why the choice of the schema specification language matters. **About Marián Varga** Marián Varga has worked with Java for more than 20 years. He wrote the book Mastering RESTful Web Services with Java and keeps helping software development projects get their integrations right. Talk 2: **OpenJDK, the JCP and JUGs: contributing to Java to become a beyond senior expert** The Java technology evolves through 3 main pillars: open source, standards and community participation. This interactive presentation will show what happens behind the scenes in those processes, how you can participate, and practical ways you can use Java's evolution to build technical expertise, and advance your career beyond the senior level. In this session you will: \- Understand the secret Java Champions use to build technical expertise \- How to think like Java's main architect\, and build impact in your project and beyond \- How to use Java's pillars to build a growth spiral for your own career **About Bruno Souza** Since 1995, [Bruno Souza](https://www.linkedin.com/in/brjavaman/) has been helping Java developers advance their careers and work on exciting projects. A recognized Java Evangelist and Java Champion, as well as a board member of the Java Community Process, Bruno founded and leads SouJava, the Brazilian Java Users Society.

ABOUT OPENCLAW Forget simple Q&A. We are entering the era of proactive AI. OpenClaw (formerly ClawdBot) is an open source framework that closes the gap between generative AI and real operational execution. AI agents operate inside everyday messengers such as Telegram or WhatsApp and autonomously perform complex business workflows. This event provides a deep dive into the architecture, capabilities, risks, and future implications of agentic systems that will fundamentally reshape how companies operate. WHY OPENCLAW OpenClaw represents a major milestone. For the first time, AI truly acts as a proactive assistant. It does not just respond to commands. It informs you, prepares briefings, and executes tasks autonomously within familiar interfaces such as WhatsApp or Telegram. This marks the transition from passive tools to operational AI agents.

Built on an xLSTM backbone, it combines recurrent state tracking and strong in-context learning with contiguous patch masking and masked inference, enabling robust forecasting and efficient uncertainty estimation. This talk outlines the key architectural and training choices behind the model, including data augmentation strategies and large-scale pre-training. Results on public benchmarks show strong zero-shot forecasting performance together with fast inference and a low memory footprint. The talk also highlights how TiRex representations transfer to downstream tasks such as time series classification, illustrating the promise of forecasting models as broader foundation models for time series. **About the speaker:** Sebastian Böck is Lead Researcher at NXAI, specializing in Deep Learning, Sequence Modeling, and Time Series Forecasting. He received his PhD in Computer Science from JKU in Linz and his diploma degree in Electrical Engineering and Information Technology from the Technical University in Munich. Long before his current focus on the efficiency and scalability of foundation models, he pioneered the application of recurrent neural networks (RNNs) in Music Information Retrieval—spanning onset detection, beat tracking, and polyphonic transcription. This early work cemented his deep expertise in state-tracking and recurrent architectures. Today, his research at NXAI centers on overcoming the fundamental scaling and inference bottlenecks of modern AI through the extended Long Short-Term Memory (xLSTM) paradigm and its application across diverse modalities. **Talk 2:** **Combining technological precision with social responsibility in training data preparation** This presentation introduces Responsible Annotation Services (RAS), a specialized All-Austrian provider of high-quality data processing. Founded as a spin-off of the non-profit Responsible Annotation, RAS leverages a unique workforce of neurodivergent experts to deliver exceptional attention to detail, pattern recognition, and perseverance - helping to create reliable, ethical, and effective AI systems. Three distinct case studies will be presented demonstrating the versatility across modalities and industries: Bank Foyer Safety: A strategic collaboration with KEBA to refine their AI assistant, KeBob. This involved the meticulous labeling of human postures and mobility aid usage to enhance real-time emergency detection in semi-public banking environments. Text Annotation: A dive into our natural language processing project with Newsadoo, showcasing how our team structures complex textual data to train advanced language models with high semantic accuracy. Air-Vehicle Surveillance: A large-scale project with Frequentis involving the annotation of approximately 5 million video frames for airport monitoring, transforming raw footage into precise training data. **About the Speaker:** Andreas Schachl is a seasoned tech leader and open source enthusiast who believes that creating a better future requires action — not just ideas. Together with his friend Hans‑Peter Kranewitter, Andreas co‑founded Responsible Annotation Services, an AI‑focused venture that streamlines the entire data pipeline. Their key to success is a neuro‑diverse team of annotation experts who consistently deliver top‑tier results at high speed, even over prolonged periods. We are looking forward to welcoming you at our April Meetup. Your VDLM organizer team.
