Complete this [CFP form](https://clickhou.se/chmeetup-cfp) and we’ll be in touch.** **_____________________________________** **🎤 Session Details: The Journey to Zero-Copy: How chDB Became the Fastest SQL Engine on Pandas DataFrame** In this talk, Auxten Wang, creator and lead developer of chDB, shares the story of how the world’s fastest OLAP engine was made to fly on Pandas DataFrames, reducing query times from 30 seconds to just 0.5 seconds. He walks through chDB’s evolution from a serialization-bound prototype into a fully zero-copy SQL engine for Pandas, covering how DataFrame and Parquet round-trips were eliminated, how Python GIL limitations were overcome, and how string handling was rethought for parallel performance. The result is true DataFrame in and DataFrame out SQL with ClickHouse speed, delivering up to 200× faster analytics, native JSON support, streaming for data larger than RAM, and a complete zero copy loop with no servers, no setup, and no friction. **Speaker: Auxten Wang, Technical Director @ ClickHouse** Auxten Wang is a Technical Director at ClickHouse with 15 years of experience designing high-performance databases, recommender of systems, and infrastructure across startups and major tech firms. He co-founded CovenantSQL and contributed storage-layer and write-query functionality to a decentralized SQL database with blockchain features, and is an active author/contributor to ClickHouse and low-level projects like jemalloc, Kubernetes, and Memcached. His background includes leading RecSys and infrastructure teams as Principal Engineer at Shopee and director-level roles at 4Paradigm, combining production ML/recsys experience with rigorous systems engineering. Early at Baidu he architected and implemented Gingko—the company’s p2p large-dataset distribution system—writing the majority of its C++ code and applying a Dynamo-inspired design. Based in Singapore, he brings a rare mix of hands-on C/C++ systems work, testing and storage engineering, and product-driven startup leadership. **🎤 Session Details: Powering Bullet's Sub-millisecond Perpetuals Trading Platform** Tristan Frizza, Co-Founder and CTO of Sierra Research, shares their multi-year journey to delivering low latency and near real time trading data, charts, leaderboards, and analytics at scale. This talk explores the evolution from data lakes and complex, painful serving architectures to a streamlined single source of truth powered by ClickHouse Cloud, highlighting the technical lessons learned in building fast, reliable analytics for demanding trading workloads. **Speaker: Tristan Frizza, Co-Founder and CTO @ Sierra Research** Tristan Frizza is the Co-Founder and CTO of Sierra Research, focused on building the financial infrastructure the world deserves. Originally from Australia and now based in Singapore, he has led the development of high-performance trading and consumer systems, including a decentralized trading platform with over 100,000 users and $15B in notional volume. Previously, Tristan worked in machine learning and data science roles at Atlassian, Nearmap, and Lumaway, to name a few, building large-scale ML systems and data infrastructure used by tens of millions of users.

Echoes on Paper is a quiet, immersive evening where sound becomes a starting point for making. Participants take part in a live soundbath and create art in response to what they hear — translating rhythm, vibration, and atmosphere into colour and mark-making. The focus is not on technique or outcome, but on noticing how sound moves through the body and onto the page. This is a slow, sensory session designed to support presence and attention. There is no sharing requirement and no expectation to “make something good.” Just time, materials, and space to explore. You will be seated on the floor with your own canvas, painting as the sound unfolds around you. What happens Begin with a short grounding and sound introduction Experience a live soundbath Paint intuitively while sound continues Move between listening, making, and pausing Leave with a finished artwork What’s included 🎧 Live soundbath🎨 Canvas, paints & materials🧻 Floor setup and protective materials🖼 Your completed artwork to take home Price 💵 $65 per person (All materials included)

Join us for a groundbreaking session on how **AI Coding Agents** are changing the game for legacy modernization. We aren't just talking about code completion; we are talking about autonomous agents that can refactor, document, and migrate entire modules with precision. ​**🚀 Session: Modernizing Legacy Projects using AI Coding Agents** ​In this deep-dive session, we will explore how to leverage the latest generation of AI agents (like Cursor, Windsurf, Devin, or custom LLM pipelines) to tackle technical debt that would normally take months to resolve. ​**What We Will Cover:** * ​**Automated Refactoring:** How to use agents to identify code smells, untangle spaghetti code, and implement modern design patterns without breaking functionality. * ​**Language & Framework Migration:** Strategies for using AI to translate old syntax (e.g., Java 8 to 21, jQuery to React) while preserving business logic. * ​**Test Generation:** How to generate comprehensive unit and integration tests for legacy code that currently has zero coverage, ensuring a safe modernization path. * ​**Documentation Recovery:** Using AI to reverse-engineer documentation from undocumented legacy systems. ​**Why Attend?** Legacy modernization doesn't have to be a painful, multi-year slog. Come see how AI agents can act as your force multiplier, turning a daunting migration into a manageable, automated workflow.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
