🔥 **Halo Bitcoiner Jakarta Barat!** ​Tema Meetup: *Bedah Bitcoin Whitepaper* ​Whitepaper-nya cuma 9 halaman. Tapi dampaknya bikin dunia keuangan nggak pernah sama lagi 😄 Di meetup ini, kita bakal “ngebedah” Bitcoin Whitepaper bareng-bareng. Bukan kayak baca jurnal, tapi kayak ngobrol sambil ngopi. Karena kadang, **jawaban besar justru ada di dokumen kecil yang jarang dibaca** 🔥 ​Kita akan bahas dengan cara yang santai dan mengalir: 🔸 Kenapa whitepaper ini ditulis dan masalah apa yang mau diselesaikan 🔸 Ide-ide kunci yang bikin Bitcoin bisa jalan tanpa pusat 🔸 Bagian-bagian penting yang sering dilewatin orang 🔸 Kenapa sampai hari ini, whitepaper ini masih relevan ​ Nggak ada tuntutan harus ngerti semuanya. Kita ngobrol pelan-pelan, biar klik satu per satu 😄⚡ Siapa tahu, setelah ini cara kamu ngeliat Bitcoin jadi makin masuk akal. ​ 📌 **Info Penting:** 🔸 *Gratis* (beli makan/minum sendiri) 🔸 No altcoin, no token, no bullshit 🔸 **100% Bitcoin.** 🔗 **Tentang Kami**🟠[ Bitcoin Indonesia](https://x.com/bitcoinindo21)[ ](https://x.com/bitcoinindo21)adalah inisiatif nirlaba yang bertujuan untuk: 🕊️ Menyebarkan pemahaman soal **Bitcoin** sebagai alat pembebasan individu ⚖️ Mendorong **kedaulatan finansial** lewat edukasi netral dan jujur 📚 Menyediakan konten edukasi **open-source & gratis** untuk semua **📲 Telegram: [https://t.me/+OIIRyKQmvJY0MWFk](https://t.me/+OIIRyKQmvJY0MWFk)** **📸 Instagram: [https://instagram.com/bitcoinindo21](https://www.instagram.com/bitcoinindo21)** **🌐 Website: [https://bitcoinindonesia.xyz](https://bitcoinindonesia.xyz/)**

Gak Seseram yang Kamu Kira! (mengungkap mitos dan fakta soal Bitcoin di dunia bisnis, plus strategi aman bagi pemilik usaha pemula)* ​ Ngopi itu enaknya sambil ngobrol hal ringan, tapi gimana kalau obrolannya justru bikin bisnismu makin matang? 😄 Banyak pelaku usaha dengar kata Bitcoin langsung mikir ribet, penuh risiko, atau nggak relevan buat bisnis kecil dan menengah.

Gak Seseram yang Kamu Kira!**, kita bakal ngobrol santai soal **mitos dan fakta Bitcoin di dunia bisnis**. Mulai dari anggapan yang sering bikin ragu, sampai realita yang jarang dibahas. Kita juga kupas **strategi aman dan realistis** buat pemilik usaha pemula bukan buat langsung lompat jauh, tapi buat ngerti pijakannya dulu ☕📊 ​Diskusinya jauh dari kesan teknis, penuh contoh yang dekat sama keseharian, dan relevan buat kamu yang lagi bangun usaha, lagi mikir efisiensi, atau sekadar pengen tahu apakah Bitcoin punya peran di model bisnis kamu. Fokusnya bukan ikut tren, tapi **mengurangi salah paham sebelum ambil keputusan**. ​Datang buat ngopi dan tukar cerita, pulang dengan pandangan yang lebih jernih.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

**Chaos Monkeys, Open Telemetry, and .NET Aspire: Taming Complexity in Modern Apps** .NET Aspire is far more than just a sleek dashboard for wowing your boss and co-workers. It's also a gateway to increased observability with open telemetry, better fault tolerance to fend off chaos monkeys, and a drastically improved onboarding experience for new developers. This session will explore Microsoft's latest guidance for building distributed, cloud-first applications, with practical strategies for enhancing simpler existing apps. You'll discover the inner workings of Aspire, from installation to customization, and learn how it streamlines integration with performance boosters like Redis. Most importantly, you'll see why scalable microservices architectures can be challenging—and how Aspire helps simplify the journey. **Presenter:** Lee Richardson, Microsoft MVP **Pizza starts at 6. Presentation starts around 6:30.**

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

Improving will be providing pizza and beverages. * 6:30 to 8:00 pm. Main meeting and presentation(s). Lonnie Morgan will be presenting information about the DLT Library. "The Python library `dlt` provides a powerful [REST API toolkit](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api/basic) to ingest data. Combined with our [LLM scaffolds](https://dlthub.com/workspace) and [MCP server](https://dlthub.com/docs/hub/features/mcp-server), you can build a custom connector for any of the 8k+ available sources in 10 minutes by following this guide. Building with LLMs is an iterative process. We will follow this general workflow and give practical tips for each step." See Our [Parking Map](https://docs.google.com/presentation/d/1u2A4fLNlxwLJn0KA_hKc8bnFlFHLvsHBDh-_8wzX_tk/edit?usp=sharing) We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact centralohpython@gmail.com
