Join us for an unforgettable night 7:30pm in Jakarta [[Click This Whatsapp Groupchat Link](https://chat.whatsapp.com/I8piLGquTos5Ty8i1Q6cl1)] We’re not just a language exchange — we’re a roaming social experience for 20s and 30s who love new faces and open conversations. Whether you're an expat, traveler, or Seoulite looking for something beyond the usual Saturday, this is the place to be. Connect, talk, laugh, repeat.

Want to unwind after work with some fun? How about hitting the tennis courts at Anol Tennis Warehouse with people who are at your level (Intermediate)? It’s a weekly event, and we’re always welcoming new members, so you can get a great workout and make some new friends all at once. Looking forward to seeing you there soon! Fee is 198,000 Rp per person.

**Let's escape the hustle and bustle of Jakarta with a late afternoon stroll through Senayan GBK Park and make some new friends along the way!** Senayan GBK Park is located in the heart of the city and is a nice place to visit and explore. Starting from Entrance 7 (Pintu 7), we will walk around and through the park and then over to Senayan Park Complex. Afterwards, we'll go to Lucy in the Sky at Spark, located on the rooftop of Senyan Park Mall for some refreshing drinks and food. This last part is optional for people who want to go. The walk will be a casual stroll around several connecting parks. The walk will take approximately 1:30 hours. We will meet just outside Entrance 7 near the main road. Please be on time, as once we start the walk it will be very difficult to locate us. However, we will post the live location on the WhatsApp Group chat. This is a fun and social event, and everyone is encouraged to get to know each other and make new friends. **📢 IMPORTANT: Attendance Reconfirmation Required** To ensure accurate headcounts and reduce no-shows, we're implementing an updated reconfirmation system for all events. **Here's how it works:** * All events start with unlimited RSVPs. * 4 days before each event, a reconfirmation form will be posted in the event comments and shared in the WhatsApp group. * You must reconfirm ASAP by submitting the form. Your spot is guaranteed only after you reconfirm. * The form closes once we reach the target attendance number. * Anyone who hasn’t reconfirmed when the form closes will be removed from the attendee list. * If you can’t attend, change your status to Not Going. **Two‑strike rule: If you don’t reconfirm and don’t change to Not Going two times, you will be removed from the group.** Thanks for helping us keep things running smoothly. Looking forward to seeing you all there. If you have any questions, please feel free to let me know here or join our friendly and active WhatsApp Group Chat: [https://chat.whatsapp.com/FBQsf4Cv4yWACNs9gbiYNH](https://chat.whatsapp.com/FBQsf4Cv4yWACNs9gbiYNH) Instagram: [https://www.instagram.com/jakartasocialgroup](https://www.instagram.com/jakartasocialgroup)

**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

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.

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. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. 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.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
