Agenda --- Hosted By Hubert Kut, Atlassian Solution Architect My journey in IT world started as a support engineer. I realised quickly that a lot of teams straggle with collaboration, transparency and tracking work done/undone. That was the time when Atlassian kicked the door down and jumpstarted my career. From that time I'm Atlassian Evangelist, Solution Architect and passionate about Agile Methodology. My business goal is to facilitate people's work by giving them tools that are available from anywhere and at anytime. Key words for myself are simplification and automation.

🥪THE SANDWICH MIC 🥪 It’s a *show up, go up* comedy open mic — 12 spots total! Bring your jokes, your friends, and your best punchlines. 🎟️ Free reservations for guests (we appreciate donations at the end). 💥 Good vibes, cold drinks, and fresh laughs every week.

\*This is a free event, but please [donate through Eventbrite](https://www.eventbrite.de/e/read-editing-monthly-writers-meetup-tickets-1981513291596?aff=oddtdtcreator) to support our collective if you are able! Please join us on the 2nd Monday of every month for this event, built for all of your “in between works“ by the [Read Wedding](https://www.instagram.com/readwedding/) collective. Most events for writers are focused around ***creation or performance***. Much comes between this, yet we do not always hold each other through that phase. It is perhaps expected that all of those self-questioning, unsure, multi-path moments between lightbulb idea and snap-inducing performances are to be personal and private -- but they do not always have to be. We therefore offer you a space for everything unfinished. Needing bouncing around. Ready for a test run. We will meet in a more traditional meetup format than our open mic -- without any set format of facilitation. We will determine the approach to each session based on who's arrived and what their goals are. You may expect some combination of solitary writing time, sharing and feedback, and guided exercises. We'd love for you to show up however you are, and with some writing materials (including your phone, if you prefer). However you arrive, so long as you are feeling curious and open, we will have something for you and your work. See you there! Brooks, Bubamarrë & Johanna Re(a)d VVedding Kollektiv \-\-\- **NOTE: Excluding select, small workshops, Read Wedding has hosted entirely free events since we started. If you have the means and would like to support us, it goes a long way.

**Join the FINALE of the free BLISS AI Speaker Series Winter 2025/26!** We are excited to feature **Ahmed Salem**, who is currently a Researcher at **Microsoft Security Response Center (MSRC)** and will discuss **"The Price of Intelligence: Three Risks Inherent in LLMs**", lasting approximately 45 minutes. After the talk, seize the opportunity to connect with fellow AI enthusiasts to share ideas and questions while enjoying free drinks and pizza. **Door close by 7.15pm, so please come early! Also, "attend"ing (RSVP) here on Meetup is strictly necessary to be guaranteed entry.** Please note that Meetup has recently been quite keen on promoting its Plus program. However, you are not obligated to purchase it, as both our events and the platform remain free. **Who is this event for?** This event is open to everyone interested in state-of-the-art AI research. We especially design it for students, PhD candidates, academic researchers, and industry professionals with a research focus in machine learning. **Abstract**: As LLMs move from passive assistants to action taking agents, the price of intelligence is increasingly paid in control failures: what the model treats as instruction, how behavior shifts across time and context, and how fragile safety properties can become under downstream adaptation. In this talk, we begin with indirect prompt injection as an end‑to‑end problem, where untrusted content can steer downstream actions in realistic pipelines. We then discuss a defense direction that secures agent planning through deterministic policy enforcement and principled control over what information is exposed during planning. Finally, we turn to a practical question that underlies all of these results: how do we know when an agent/LLM is actually safe, rather than merely scoring well on an evaluation? We highlight two factors that can systematically distort safety measurement in agent settings. First, reasoning models can change compliance when they infer they are being evaluated (“test awareness”), which can bias apparent robustness and complicate safety audits. Second, we discuss implicit memory as a hidden channel that challenges the “stateless” assumption and enables temporal behaviors that standard evaluation setups may fail to surface. **Bio**: [Ahmed](https://ahmedsalem2.github.io/) is a Researcher at the Microsoft Security Response Center (MSRC), focusing on machine learning privacy, biomedical data privacy, and applied cryptography. He was previously a Postdoctoral Researcher at Microsoft Research Cambridge (2022–2024). He received his PhD in Computer Science from CISPA Helmholtz Center for Information Security, Saarland University, under the supervision of Michael Backes and Yang Zhang, graduating *summa cum laude*. Before that, he earned his MSc in Computer Science from Saarland University with high honors and his BSc in Digital Media Engineering from the German University in Cairo. His work has appeared at ICML, USENIX Security, CCS, NDSS, and Oakland. We are [BLISS](https://bliss.berlin/) e.V., the **AI** **organization** in Berlin that **connects like-minded individuals** who share great interest and passion for the field of machine learning. This winter 2025/26, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from Tübingen AI Center, DeepMind, Microsoft, King's College London, cohere, and ETH Zürich.

What if your frontend could directly manage data, authorization, and collaboration - without domain-specific backend code?* *In this talk, Oliver shares how he built a triplestore-based BaaS to power real-time collaboration in his side project MonsterWriter, and how the approach grew into an independent open-source project. We’ll see how LinkedRecords.com enables fine-grained authorization, simplifies real-time collaboration, and supports a Bring Your Own Backend model that gives organizations more control over their data and vendor relationships. It is also shown how global state management becomes a lot easier in React apps.* **➡️ Building Cross-Platform Agentic UI at Superhuman** *Recently, Superhuman (formerly Grammarly) launched Superhuman Go, an AI assistant that works alongside you on every platform. To build it, we needed a scalable solution that supports an unlimited number of agents that dynamically shapes the user interface and looks similar across all supported desktop and mobile platforms.

### 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.
