(And Why That’s the Best Part) By Goutham Veeramachaneni** I’ve been experimenting with [Beyla](https://grafana.com/oss/beyla-ebpf/) and [eBPF-based monitoring](https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation) since its inception. While it’s an incredible tool for getting started with zero-code instrumentation, making it work reliably at scale presents a unique set of hurdles. In this session, we’ll introduce Beyla’s architecture and show how it can kickstart your observability journey.But the real story lies in what happens next. Navigating the scaling challenges has been an absolute blast, and we’ve tackled each bottleneck unfazed—sometimes by leaning into the tech, and other times by resorting to white box native instrumentation to gain the granular insights we need.What you’ll learn: * • **The "How":** A technical deep dive into how Beyla works under the hood. * • **The "Real-World":** The specific challenges we faced when moving beyond the initial phase. * • **The "Trade-offs":** A transparent look at the limitations of different approaches, from pure blackbox eBPF to native instrumentation. * • T**he "Product":** Insight into the intricacies of building a new product in a rapidly evolving ecosystem. Whether you are an observability veteran or just starting with eBPF, you’ll walk away with a better understanding of your monitoring stack and the confidence to handle the limitations of the tools you use. ### **Talk 03: Securing and governing both external and internal traffic By Sven Walther** Modern enterprises must secure and govern APIs, event-driven systems, and internal services—without fragmenting control across multiple platforms. This talk shows how a unified management plane brings consistency, visibility, and security across the entire application landscape using Kong Konnect. The session will cover three key areas: * **External connectivity & event exposure** Securely connect partners and customers to your event-driven systems without exposing internal infrastructure directly. * **Internal service governance with Service Mesh** Apply security, traffic control, and observability across your internal network using a service mesh. * **Fine-grained Kafka governance** Enforce policies and security down to the individual message level for internal event streams. *** ### **🤝🏻 21:00 — Networking & Q&A** Connect with fellow developers, data engineers, platform teams, and observability enthusiasts. Share ideas, experiences, and maybe even exchange a LinkedIn connection or two. **21:30 — Event Wrap-Up** *** **📷 Photo Notice** By attending this event, you consent to being photographed. These photos may be used for future community and event promotions. Don’t forget to smile 😄 *** We’re excited to kick off 2026 with the Berlin community and can’t wait to see you there! If you have any questions or are interested in **speaking at future meetups**, feel free to reach out.

Ein Treffen für Frauen ab etwa 28, die spüren, dass mit mehr Klarheit auch der Wunsch nach Verbindungen wächst, die wirklich zu ihnen passen. Dieses Meetup ist ein offener Raum für ehrliche Begegnungen, echte Frauen Freundschaften, und weibliche Energie. Ohne Konkurrenz. Ohne Erwartungen. Bei Kaffee, Brunch oder Frühstück zusammenkommen und einfach wir selbst sein, spaß haben und vielleicht schon bald den nächsten trip planen. Ich wünsche mir selbst mehr weibliche Energie in meinem Alltag und weiß, dass ich damit nicht allein bin, deshalb freue ich mich auf euch und vielleicht ist das hier der Anfang einer neuen Sisterhood. 🎀

I'm excited to announce another meetup! If you're interested in give a talk, feel free to reach out to me at marcel.drechsler@andsafe.de \-\-\- All talks will be **presented in English**, to ensure that as many people as possible can participate and engage at this event. **If you want to attend, please RSVP to secure your spot - this will make organizing easier. Thank you so much ♥️** **Location:** Spiced Academy, Ritterstrasse 12, 10969 Berlin, 2. Hof \-\-\-\-\-\- **🏠 18:00 - Arrival: Networking, Drinks & Snacks (30 min.)** Grab yourself snacks & drinks and say hello to everybody else! **📅 18:30 - So you want to observe an Event Driven System? (45 min.)** **🎙️**Speaker: Roman Boiko, Enterprise Sales Engineer @ [Datadog](https://www.datadoghq.com) Event-driven architectures offer powerful decoupling, but they often shatter traditional monitoring strategies. When a single business process jumps across multiple queues, buses, and microservices, tracing the line between cause and effect becomes a complex puzzle. This talk bridges that visibility gap by exploring practical observability strategies using OpenTelemetry. We will navigate the critical architectural decisions behind distributed tracing - specifically choosing between Span Linking and Parent-Child relationships - and master context propagation to ensure no transaction is lost in the noise. Join us to learn how to connect low-level technical data with high-level business metrics, turning asynchronous complexity into a clear, manageable system. Roman Boiko is a Senior Enterprise Sales Engineer at Datadog, where he helps developers and architects build reliable, observable, and scalable systems. With a strong background in serverless and cloud-native architectures, he’s passionate about bridging the gap between engineering and operations to help teams move faster with confidence. Roman frequently speaks at tech events, sharing practical insights on observability, distributed systems, and modern application design. He enjoys exploring how developers can simplify complexity and deliver better software through data-driven decisions. **📅 19:15 - Datadog at Zendesk - a solid foundation for scalable, reliable and cost efficient systems (30 min.)** **🎙️**Speaker: Anatoly Mikhaylov, Principal Software Engineer & Datadog Ambassador @ [Zendesk](https://www.zendesk.de/) Anatoly will share practical and valuable lessons what value Datadog brings and what role it plays at Zendesk. They customized and encorporated observability triad (APM, Logs and metrics) within a large volume of systems and applications. Zendesk made it work very well at scale and so that Datadog became a common language engineers and product teams can speak to one another. A single picture often helps to narrow down the issue, surface the problem, brings the solution and be confident remediation is applied successfully. Zendesk teams are fluent using complex Datadog tools and drive necessary changes. **📅 19:45 - Continuous Profiling with Datadog (30 min.)** **🎙️**Speaker: Felix Geisendörfer, Senior Staff Engineer @ [Datadog](https://www.datadoghq.com) Instrumenting systems with logs, metrics and traces is a great way to make them more observable. However, the resulting map is not the territory, and only allows indirect reasoning about the code it represents.Continuous profiling fills this gap by allowing software developers and operators to directly understand the CPU, Memory and Latency trends of their systems using stack traces that break down problems and opportunities in terms of files, functions and line numbers. This presentation will demonstrate the value of this capability by live-debugging an incident caused by an AI assisted refactoring using Datadog’s Continuous Profiler product. Additionally the presentation will give an overview of other capabilities as well as the work we’re doing upstream to add profiling as the fourth signal of OpenTelemetry. **🥗 20:15 - Drinks, Food & Networking** Enjoy refreshments while networking with community peers! **👋 21:00 - Goodbye, see you next time!**

Kick off the new year with our first gathering of 2026! As the days get colder, we’re bringing the Flutter community together for an evening of fresh inspiration and cutting-edge tech. Join us at Knowunity for a night of learning, networking, and a deep dive into the future of user interfaces. **Schedule** **18:30 — Doors Open & New Year Welcome** Check in, grab a drink, and catch up with the community as we start the year strong. **19:00 — Opening Remarks** A greeting from Flutter Berlin and our hosts at Knowunity to kick off the evening. **Talk 1 — From Prompts to Pixels: LLM-Powered Interfaces using Generative UI** Imagine asking an LLM a question and instead of receiving a static wall of text, you receive a fully tailored interactive interface that's built on the fly, specific to your task. In this talk, we'll dive into Google's new Generative UI paradigm and how it can be applied with Flutter. You’ll learn what it's capable of today, how it works under the hood, and how you can start integrating Generative UI patterns into your own Flutter applications. **Talk 2 — Pushing the boundaries of Dart and Flutter** This talk takes you on a short but unconventional journey: from re-implementing core Flutter concepts from scratch in the terminal, to building a coding agent on top of it - and eventually making Flutter run inside Minecraft. Along the way, I’ll share the technical challenges, unexpected lessons, and finally reveal why I actually did all of this in the first place 🙂 **20:00 — Networking** Meet fellow Flutter devs, exchange ideas, and chat over snacks. **22:00 — Doors Close** We say goodbye and step back into the crisp January night.

Let’s meetup at Cafe Istanbul for the last day of Restaurant Week. You get three courses for $30. This is the menu: https://614now.com/rw-menu/cafeistanbul-easton

This is "***New Members Night***." If you are one of the many folks on the fence about coming to your first wine tasting with the *Hilliard Wine Club*, this is the night to come. There will be many other new people, so you won't be alone. And the regulars will be there to help make you feel welcome. We're a relaxed and warm group. We hope to see you. **SIDE NOTE:** New members are welcome to ALL our Friday night wine tastings, but this night is a special overture to those who don't want to feel that they are the only new person in the room. Don't worry. You won't be. And don't hesitate to RSVP to other events. **OLD MEMBERS NOTE**: Hey Old Members! You're not excluded from this event. We expect to see you there to help make the new members feel welcome. **Sample 4 different wines** this Friday for $15 (*Cash or Venmo only please*). Glasses are provided. Bring a snack to share. Bring a bottle to share if you care to. See all the details below for the Hilliard Wine Club Wine Tasting. In Person. In Real Life. Actual Wine from glass bottles with corks and everything. **Wine**: Tastings will be $15 for four samples as always. And you are welcome to bring a bottle of your favorite wine to share with others. Participation in the wine tastings is optional. But since you’re going, I will buy enough wine to cover you. If you bring your own wine and do not participate in the tasting you will only pay $10 to cover the door charge. **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. **Glasses**: …will be provided. Please note that after the wine tasting, the glasses need to be returned to the boxes at the service table. 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. **Extra Wine**: After everyone has had their samples, we remove the pouring spouts and any remaining wine is poured freely to whomever wants it. I hate having leftover wine. **Queen of Hearts**: The Queen of Hearts raffle is a fundraiser for the club and a Barnum and Bailey type extravaganza - minus the dancing ponies, clowns, and actual circus. Bring your ***cash*** as the Queen does not accept American Express or other plastic. **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*
