This panel brings together identity leaders to challenge today’s assumptions, debate what’s hype versus real architectural shift, and explore where existing identity guidance breaks when agents start acting on our behalf. Through sharp, opinion-led questions on delegation, standards, continuous decisioning, and auditability, panelists will surface the principles and industry changes that will matter most in the next 12–24 months. **7:30pm -** Network **8pm -** Event and attendees exit venue Have a great day, An

### Thursday Evening Discussion Group **In\-Person \| Starts at 8:00 PM \(Doors open at 7:30 PM\) \| Drop\-In** **Starting material:** *[Network of Thought](https://www.holybooks.com/wp-content/uploads/Network-of-Thought-Krishnamurti-ebook.pdf)* by **Jiddu Krishnamurti** This weekly discussion group offers a reflective and open space to explore themes of **mysticism, spirituality, and inner transformation** through selected writings and talks by Jiddu Krishnamurti, Annie Besant, Alice Bailey, and other thinkers whose work invites deep **inquiry into consciousness, freedom, truth,** and **the nature of self-understanding**. Rather than promoting a particular belief system, the group emphasizes **shared reading, thoughtful reflection, and respectful dialogue**. Participants are welcome to engage at their own pace—whether through listening, contemplation, or open discussion. While there is **no requirement to commit before attending**, *the intention is to gradually build a group of participants who are interested in returning regularly and engaging sincerely with the material* and the group process. Newcomers are very welcome, and those who feel drawn to ongoing study are warmly encouraged to continue attending. This is a **drop-in group**, and no prior background or preparation is required. **All are welcome.** Come as you are, reflect together, and take part in a spirit of openness and mutual respect.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/xwjDdVSw3E **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

你有没有试过，让 AI 替你读一本书？ 十秒钟，梗概有了。 一分钟，重点也有了。 再问几句，它还会解释、比较、反驳。 很方便。也有一点可疑。 一本书，只看 AI 总结，算读过吗？ 工具书也许可以。 小说呢？传记呢？ 那些在某一页突然停住的时刻呢？ AI 能说出《悉达多》讲了什么。 哪一句会在你心里留下来，只有你知道。 **第一期「AI双面圆桌派」，我们聊：** **当 AI 可以总结、解释、陪读、反驳一本书时，人还为什么读书？** 我们该读得更多，还是读得更慢？ 我们和三位嘉宾一起，聊几个问题： * AI 眼里的重点，是我的重点吗？ * 读得快，会不会只是更快地产生“我懂了”的错觉？ * 哪些书可以交给 AI 先读？ * 哪些书，还是要自己慢慢读？ * 故事、共鸣、经验，算不算知识？ 两个小环节： * AI 帮我省下一小时。 * 我用 AI 搞砸的一件事。 带着问题来就好。 不用先有答案。 ***嘉宾介绍*** Anna，深耕北美市场营销与中国科技，互联网产品出海，腾讯，IDG投资的企业级AI软件小鹅通elink加拿大负责人，专注企业增长与数字化转型。 * 主导多个品牌北美市场进入与增长项目，实现从0到规模化增长 * 推动小鹅通eLink在加拿大落地，赋能企业私域与数字化转型 * 深度连接中美加商业资源，搭建跨境合作与行业生态网络 Swan, 加拿大注册会计师（CPA），7年审计经验，横跨财务审计与运营审计。曾先后任职于加拿大知名会计师事务所、五大银行，及政府审计部门。拥有横跨三类组织的审计实务经历，擅长从财报中梳理逻辑、发现问题，并快速理解运营流程、防范风险。作为误闯创业群的一名风险“守门员”，习追问，习惯质疑，抽丝剥茧，追本溯源。也是夹缝中生存的打工人，探索如何用AI杠杆减轻负担、加速成长。 张英锋，QHOW Technology 创始人，科技教育与知识传播实践者，长期关注 AI 时代的学习方式与认知模型重构。曾获知乎“2014 年度新知答主”，在科学、数学、教育、历史等领域创作 160 多篇回答和文章，累计阅读超过 3700 万，拥有 26 万关注者。在本场圆桌中，他将从一个略带“反方”的角度讨论 AI 阅读：AI 总结带来的，究竟是真正的知识，还是一种“我已经懂了”的幻觉？他关注的问题是，当 AI 可以快速提炼一本书时，人如何避免停留在叙事共鸣中，而是真正把阅读转化为理解、输出与解决问题的能力。 ***About Startup4Chinese*** Started in August 2017, Startup4Chinese's mission is to INSPIRE, EMPOWER, and CONNECT entrepreneurial minds not only among Chinese but beyond.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture. Furthermore, metadata-driven design patterns show how configuration tables and dynamic notebook orchestration eliminates hard-coded pipelines. The deck covers star schema modeling, guidance on choosing between Spark, Pandas, and SQL, and data quality enforcement using DQX with YAML data contracts. Finally, we dive into security best practices and performance optimizations. **Host:** Justin Shea, Mehdi Jeddi, Erik Pak, and Sou-Cheng Choi **Talk Format:** This is a hybrid event.
