In this session, Alexey will take a deep dive into how large language models are trained, fine-tuned, and served, with a focus on the data pipelines and architectures that make it all work. You’ll see live demos of ClickHouse tackling massive AI-scale datasets in real time, along with performance benchmarks that reveal just how far you can push the engine.

You'll get a behind-the-scenes look at the architecture decisions, ingestion pipeline design, and optimizations that made the migration work — along with live demo showing the performance gap between the two engines on real marketplace data.

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.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

**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
