Decentralized Systems & Applications

**🎬 Ethereum Slovenia is back in the new year and we’re starting strong.** Just like last year, when we opened the year with *Vitalik: An Ethereum Story*, we’re kicking off 2026 with another powerful film that goes to the very core of crypto ideology. This time, we’re screening **Code is Law**, a gripping documentary that dives deep into the most dramatic hacks, legal grey zones, and ethical dilemmas in the history of decentralized technology. 📍 **Hotel** **One66** 🗓 **29 January 2026** ⏰ **19:00** **Timeline:** Doors: **18:30** 🚪 Code is Law: **19:00** 🍿 Networking and drinks: **20:30** 🥂 *** **About the film** Hundreds of millions of dollars have been stolen in massive crypto heists — yet the hackers claim they broke no laws. *Code is Law* exposes an unprecedented crime spree in the world of cryptocurrency, told through the eyes of cyber vigilantes chasing highly sophisticated attackers who argue that if the code allows it, it’s not a crime. At the center of the story is a teenage math prodigy who stole $64 million, mocked his victims, and became the first to seriously test the infamous “code is law” defense — before vanishing as an international fugitive. The film traces the origins of the *Code is Law* movement from the infamous $50M DAO hack, through the rise of Andean Medjedovic — the Indexed Finance and KyberSwap hacker — whose actions challenged the very definition of crime, responsibility, and justice in decentralized systems. This is not just a story about smart contracts and exploits — it’s a deeply human story about power, ideology, accountability, and what happens when self-executing code collides with a faceless legal system. *** **Festivals & Recognition** * 🎖 Julien Dubuque International Film Festival 2025 — Official Selection * 🎖 Atlanta Docufest 2025 — Official Selection **What critics say** * “A gripping, high-stakes techno-thriller” — *IndieWrap* * “Incredibly riveting… A cathartic experience” — *UK Film Review* * “A masterpiece” — *Samczsun, Founder of Security Alliance* * “Fascinating — and terrifying” — *FilmThreat* *** Join us for an evening of film and networking, and let’s start the year by questioning one of the most controversial ideas in crypto: **Is code really law?** 🍿⚖️🧠

🌞 The January meetup of AWS User Group Ljubljana is coming up, and we're gathering once again at Sputnik! \-\-\- Marko from ServerlessLife will take us on a journey through serverless. This lecture is intended for anyone, regardless of their level of serverless knowledge. We will begin by discussing how to get into serverless and the key challenges to be aware of. We will cover the main services, review common design patterns, and explain how serverless development differs from conventional development. We will also look at current trends and some of the latest features. In the second part, we will move to a more advanced level. We will examine AWS service gotchas and design patterns that can lead to unexpected outcomes—and, in some cases, silent data loss. Whether you are a beginner or an experienced practitioner, this talk will provide practical insights and valuable takeaways. \-\-\- Urban Jurca will present AWS European Sovereign Cloud—AWS's answer to European data sovereignty requirements. We'll explore what this means for organizations operating in the EU and how it fits into the broader cloud landscape. See you there! 🍻❄️ 📅 Agenda: * 🎤 Marko (ServerlessLife): How to Succeed with Serverless in a Post-Serverless World * 🎤 Urban Jurca: AWS European Sovereign Cloud * 📍 Location: Sputnik, Tržaška 128, Ljubljana * 🕕 Date: January 29, 2026 at 18:00 🙏 Please confirm your attendance so we can prepare the space accordingly.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group × DevOps Columbus** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS, Columbus HashiCorp User Group, and DevOps Columbus meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/azure-cbus-2026/

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development

### 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.
