👋 **Hei, kamu yang percaya hal besar selalu dimulai dari obrolan kecil...** ​ Nggak ada komunitas yang langsung besar dan kuat.

Perubahan tutupan lahan merupakan salah satu indikator penting dalam perkembangan suatu wilayah. Dengan melihat perubahan tutupan lahan, kita bisa melihat bagaimana alih fungsi lahan di sebuah area berlangsung dari waktu ke waktu. Dalam konteks lingkungan, tutupan lahan yang berubah bisa menunjukkan berkurangnya luas hutan di wilayah tertentu. Itulah kenapa, banyak jurnalis, peneliti, aktivis, dan berbagai pihak lain menaruh perhatian besar terhadap perubahan tutupan lahan. Akan tetapi, untuk menginvestigasi perubahan tutupan lahan, dibutuhkan pengetahuan dan keterampilan tertentu. Itulah kenapa, webinar bulanan Journocoders Indonesia ini akan membahas bagaimana kita bisa menginvestigasi perubahan tutupan lahan, terutama dalam konteks Indonesia. Webinar ini akan menghadirkan **jurnalis Harian Kompas, Albertus Krisna,** sebagai pembicara. Krisna merupakan anggota tim Jurnalisme Data Harian Kompas yang terlibat dalam liputan tentang penyusutan hutan di Sumatera yang dipublikasikan pada Desember 2025. Liputan berjudul "Hutan Sumatera Lenyap" itu sempat viral di media sosial beberapa bulan lalu.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

**Caller: Richard Ades** **Band: The McKenzies** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
