Hello everyone! We're very excited to be hosting an **IN-PERSON** meetup in Jakarta. We look forward to seeing you there! The address, agenda, and speaker information can be found below. See you there! **📍 Venue:** WeWork Revenue Tower Scbd, Jl. Jend. Sudirman No.52-53, Senayan, Kebayoran Baru Jakarta, JK 12190 Room 25A **Important:** * To obtain an elevator pass, all visitors are required to exchange their ID/driver's license/passport in the building lobby's reception area. \*\*\* **🗓 Agenda:** * 7pm: Doors open * 7pm - 7:30pm: Pizza, Drinks, and Networking * 7:30pm - 8:00pm: Gandhi Manalu Senior Customer Success Technical Architect, Confluent * 8:00pm - 8:30pm: Additional Q&A & Networking \*\*\* **💡 Speaker:** Gandhi Manalu Senior Customer Success Technical Architect, Confluent **Talk:** Kafka Consumers, Evolved - Exploring KIP-848 & KIP-932 **Abstract:** Kafka's consumer model is evolving fast. This talk will revisit the fundamentals of partitions and consumer groups, then dives into KIP-848, the new rebalance protocol that makes rebalances more incremental, reduces stop-the-world disruption, and keeps unaffected consumers moving. From there, we will explore KIP-932 and share groups, showing how Kafka is gaining queue-like consumption patterns that can scale processing beyond the classic one-partition-per-consumer limit. If you build Kafka applications and want an accessible, forward-looking look at where consumers are headed next, this session connects the protocol changes to real-world scalability, elasticity, and new application design patterns. \*\*\* ***DISCLAIMER*** BY ATTENDING THIS EVENT IN PERSON, you acknowledge that risk includes possible exposure to and illness from infectious diseases including COVID-19, and accept responsibility for this, if it occurs.

🎉🔥**Road to Unconference 2026!**🔥🎉 **Event terbesar [My First Bitcoin](https://myfirstbitcoin.org/) di Asia akan segera hadir 🚀** **Kita akan mengadakan Bitcoin Unconference pertama kami—** **mengumpulkan pemula, alumni, hingga Bitcoiner dari berbagai penjuru dunia.** **📍 Surabaya — 22 Agustus 2026** **🚨Tempat terbatas.** **Kalau kamu mau jadi bagian dari ruang diskusi yang beda…** **👉 amankan tiketmu sekarang:** **[unconference.bitcoinindonesia.xyz](https://unconference.bitcoinindonesia.xyz/)** Halo Bitcoiner Jakarta! 👋 Kita sering fokus ke “cara pakai” Bitcoin—kirim, terima, simpan. Tapi ada satu hal yang sering baru kepikiran belakangan: privasi. Sebenarnya, seberapa banyak jejak yang kita tinggalkan saat bertransaksi? 🤔 Di meetup kali ini, kita bakal ngobrol santai tentang *Privasi dengan Fedi*—sebuah pendekatan yang mencoba bikin penggunaan Bitcoin jadi lebih nyaman tanpa harus terlalu terekspos. 🔐⚡ Kita akan bahas kenapa privasi itu penting, bukan karena mau “sembunyi”, tapi karena ini bagian dari kontrol atas diri sendiri. Dari situ, kita juga bakal lihat bagaimana Fedi bekerja dan kenapa konsepnya menarik untuk dipahami. ☕ Nggak perlu khawatir kalau kamu belum familiar—kita bahas dengan cara yang santai dan mudah dicerna. Justru ini jadi kesempatan buat mulai paham dari dasar, tanpa harus lompat ke hal yang terlalu teknis. 💡 Menariknya, dari topik ini biasanya cara pandang kita ikut berubah. Bitcoin jadi bukan cuma soal teknologi atau aset, tapi juga tentang bagaimana kita menjaga ruang pribadi di dunia digital. 🌐✨ Meetup ini cocok buat kamu yang ingin menggunakan Bitcoin dengan lebih sadar dan bijak, atau sekadar penasaran dengan topik privasi yang sering dibicarakan di komunitas. 🤝 Yuk gabung dan eksplor bareng bagaimana privasi bisa jadi bagian penting dalam perjalanan kamu menggunakan Bitcoin. Sampai ketemu di meetup! 🚀⚡ ​\*\*[Bitcoinstitution – Helping visionary business leaders to beat inflation & survive the World War III](https://goakal.com/bitcoinstitution)\*\* ​ **👤 LEADER KOMUNITAS JAKARTA: [BANG RICKY](https://goakal.com/bitcoinstitution)** ​Bang Ricky — motor penggerak komunitas **Bitcoinstitution Jakarta**.

UP! AND! WRITE! #55!** Everyone is always welcome to join our events. Our community is all about creating authentic in-person connections in this urban jungle. Come as you are... it’s the best version of yourself. **ABOUT THE EVENT** So, you want to write? Then shut up and write! Writing is 0.01% "inspiration" and 99.99% getting down to it. We will meet for a circa **2,5 hour writing session at Unfinished Coffee in Blok M**, a hip open space coffeeshop near the brand new Barrito Park. It doesn't matter if you are an established writer or if you are picking up pen and paper for the first time. **Just show up, get down to it, and start writing.** Everyone will be working on their own thing, and we won't talk during writing. If you need some prompt or suggestion on what to write, I'll be happy to give you some ideas. After the circa 2,5 h writing session session, we will switch off our laptops and close our notebooks (but if you want to keep going, feel free!) and chill down. We can also share each other texts and give feedback, if that's something someone would like to do. **The rules of the game:** 1. We aim to start together in order not to disrupt the process for everyone. Please be on time. 2. No talking at the table during writing! After arriving at the table, we will focus on our own writing 3. You can take as many breaks as you want of course Don't be late as we want to start writing together, and please do **update your RSVP at least 24h before the event** if you cannot come, else you will take away a spot from a person in the waitlist.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
