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.

In 2021, Alexey came together with two co-founders to build ClickHouse and is focused daily on expanding its capabilities and optimizing performance.

Ask him about speed, or CI, go on... we dare you! **🎤 Session Details: Speed as a Feature: Markethac's Journey from BigQuery to ClickHouse** Every e-commerce insight starts with a question — but when your data grows faster than your queries can run, the answers stop coming in time. In this session, Adhitya will walk through how Markethac migrated its analytics stack from BigQuery to ClickHouse to meet the real-time demands of Indonesian e-commerce intelligence at scale. 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. If you're sitting on a growing analytical workload and wondering whether your current warehouse can keep up — this one's for you. **Speaker: Adhitya Cahyadi, Business Director @ Markethac** Adhitya Cahyadi is the Business Director and Chief of Product at Markethac, an e-commerce intelligence platform built for the Indonesian and Southeast Asian market.

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.

**Karaoke Night**: Bring your glee club friends. Enjoy a flashback to your choir days. No chorus line. It's all you baby. Sing. Shout. Scream. Lip sync if you need to. But do show up and do have a good time. **On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours. **Glasses**: …will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass! **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host*

Dodgeball is back again! If you’ve been wanting to come out, this is an easy one to join. We’ll be playing for about 1.5 to 2 hours, you do not need to bring any equipment, and no experience is needed. We use a specific set of rules and equipment to make the games run better and keep them fun for everybody, not just people who already know how to play. If it rains, the event will be canceled.
