Hi, my name is Nigel. I graduated from Nanjing University of Aeronautics and Astronautics and began my career designing rocket components for China’s aerospace program. So unlike the so-called “rocket scientists” on Wall Street, I am the real deal. For the past 20 years, I have helped foreign businesses achieve a smooth landing in China, navigating everything from market strategy and regulatory compliance to local partnerships and execution. I speak the languages of engineering, mathematics, and cross-border business. Let us have a cup of tea at a peaceful Buddhist temple and talk business. We can brainstorm practical, real-world approaches to doing business in China. My associate and I also host business networking events and organize trips around China for professionals and entrepreneurs. Please add the WhatsApp contact above to connect and confirm details.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

Central Ohio Radio Enthusiasts—CORE—is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. Ham radio operators, GMRS users, Meshtastic fans, software-defined radio nerds, makers, and technical and non-technical folks are all welcome. No experience required or expected. This month we have **WiFi HaLow: Introduction and Practical Use** with **Alex Barbur**. Details are are [core.radio](https://core.radio).

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier! Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is brought to you by the Dianetics and Scientology life improvement center.

Builders, creators, architects, admins, consultants - come one, come all. This one's for you. We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform.

So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.
