Software Craftsmanship

Hello fellow Symfonians, we are thrilled to announce the first user group meeting of the year, featuring two insightful talks that you **won't want to miss**! This time we are hosted by c-base (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Talk 1: "Agentic coding with OpenCode" by Damijan Cavar** 19:50: Break & Snack 20:00: **Talk 2: "Composer Deep Dive" by Nils Adermann** 20:40: Socializing **Talk Details:** **Talk 1: "Agentic coding with Opencode" by Damijan Cavar** Summary (ChatGPT generated): AI coding assistants are evolving beyond “vibe coding” toward **agentic, spec-driven development**. This talk explores why prompt-based workflows break down at scale and how structured specifications create a reliable foundation for autonomous coding agents. You’ll see how **OpenCode**, an open-source, model-agnostic coding agent, uses planners, implementers, and reviewers to turn specs into verifiable code while keeping context small and repeatable. The session also covers practical security considerations, sandboxing strategies, and real-world lessons from using agents on non-trivial projects. **Talk 2: "Composer Deep Dive" by Nils Adermann** This talk will take the audience on a deep dive into Composer. We'll start on the surface with the big picture of Composer (how exactly do require/update/install relate to json/lock/vendor), followed by commands and arguments not widely known and used (e.g. bump, why/why-not, update options like --with-all-dependencies, --minimal-changes, and --ignore-platform-req=php+ and what exactly the plus means). We'll then advance to the underlying concepts like the platform repository, security concepts around Composer plugins and answer questions like "Why is there a hash in the lock file and how to resolve conflicts?", or "Why do repositories need to be defined on the root composer.‎ json?" and finally reach into dependency resolution with a quick explainer on how Composer uses a SAT solver and boolean algebra to decide which packages to install. Back above water, the talk will end with an outlook on changes we're planning for Composer and [packagist.org](http://packagist.org) in the future. Don't miss these insightful talks, engaging discussions, and networking opportunities. We can't wait to see you at the **February Symfony User Group**!" If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

Let's talk Android! This month, we are at SumUp and are welcoming these amazing opportunities: **Android AI Workflows** - *Frank Tamre* I will share a practical, what i sue set of AI workflows I use in Android projects to ship faster without sacrificing code quality. This isn’t a “prompt engineering” talk; It’s a set of repeatable patterns that can integrate into Android engineering. **Crafting Idiomatic APIs with Kotlin and Compose** - *Ash Davies* In this talk, we’ll dive into the principles of idiomatic Kotlin and explore how they apply to designing Compose APIs. You’ll learn how to leverage Kotlin’s language features, from DSLs and inline functions to advanced type safety and composable conventions, to craft APIs that are a joy to use. By mastering these techniques, you can deliver APIs that not only “work” but truly feel like Kotlin. **Your Talk here** - *You* *{Insert your talk topic here}* Afterwards, we welcome you to stay and socialize (or sit in the corner listening) with or against our community. Happy Coding / Prompting / Designing / Leading / Working.

Classes every Monday, Wednesday and Friday from 19:00 to 21:00. **!!SIGN UP HERE**: [Katori Shinto-ryū Berlin Sign-up (google.com)](https://docs.google.com/forms/d/e/1FAIpQLSeBt4A13VgnEcgQQ2PDaruthmYMRWineG4KtUCKsuC9KBsCUQ/viewform) Registration is required before your participation so that we can prepare enough training equipment. **Address**: Belziger Str. 25, 10823 Berlin. **No previous experience required!** The classes are in English and German. **Our website**: [Kenjutsu Berlin - Official school of Katori Shinto-ryu in Berlin (katoriberlin.org)](https://katoriberlin.org/) **Katori Shintō-ryū** is one of the oldest Japanese sword fighting traditions (koryū) still practised today and is recognized by the Japanese government as a cultural intangeable asset. The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.

Join us for a hands-on workshop by Olena Kutsenko on Wednesday, February 25th from 5:30pm hosted by SPACE SHACK Coworking! 📍**Venue:** **SPACE SHACK Coworking** Akazienstraße 3A, 10823 Berlin, Germany 🗓 **Agenda:** * 5:30pm – 6:00pm: Welcome, Food/Drinks & Networking * 6:00pm - 8:30 pm: Workshop by Olena **📌 So that Olena has an idea of audience priorities, please fill in the [pre-workshop form](https://docs.google.com/forms/d/e/1FAIpQLSeJsBjgkL2EXvPtBScXtI5yAv6N9gFg64QmMajMUiMmaPllxQ/viewform?usp=sharing&ouid=117948459316244235775) when you can (no personal info is collected)** **💡 Speaker & Workshop Details:** Olena Kutsenko, Staff Developer Advocate, Confluent **Hands-on workshop: real-time flight data streaming, anomalies, predictions, and visualizations** **Workshop Overview** In this hands-on session, we'll build a real-time analytics pipeline using flight data and modern streaming tools — step by step, and without hand-waving. We'll start by streaming data into Apache Kafka using Confluent Cloud, process it with Apache Flink, and land it in Apache Iceberg using Tableflow. From there, we'll query the data with Trino and turn it into dashboards using Superset. Everything runs in a practical setup you can reproduce later, including Docker and cloud-managed services. Along the way, we'll also look at anomaly detection and simple predictions using built-in functions, so you can see how real-time insights can be added without building custom ML pipelines or complex models. This session is all about doing, not slides. You'll see how the pieces actually fit together, what decisions matter in practice (regions, credentials, formats), and how to go from streaming data to analytics in a way that scales. If you're curious about real-time analytics, Kafka + Flink in the cloud, or how streaming, analytics, and lightweight predictive use cases come together in the same pipeline, this workshop will give you a clear, working mental model — and code you can take home. No prior experience with Kafka, Flink, or Iceberg required! Just bring your curiosity and a laptop! **Technical Prerequisites:** To make sure you can get hands on during this workshop, please make sure the following are installed on your system (**Make sure your bring your laptops!)** **1\.

**Silent Meditation** I've organized a space and have been leading silent meditation sessions there for a few months now. It consists of 20 minutes of sitting meditation, 5 minutes of walking meditation, and then another 20 minutes of sitting meditation. The idea is simply to have a space and a set time to meditate. You could, in principle, meditate at home, but then you'd rather unload the dishwasher, check your emails, or sort your socks. Besides, it's nice to sit quietly with other people. The room is a kind of small multipurpose space. It's nicely minimalist, without any frills, Buddha statues, or incense. There are yoga mats and blocks available for sitting. Feel free to bring your own meditation cushion, though. The meditation sessions take place every Thursday from 6:30 to 7:30 p.m. in the group room of the community center in the Körnerkiez neighborhood. There's no charge (no donations). Just drop by whenever it suits you. Feel free to contact me if you have any questions. https://www.nbh-neukoelln.de/angebote/offene-meditation/

We're super excited to see our guest now stepping into the presenter's role. About his keynote: "You have data, analysts, and business use cases. But you can't simply stitch them together with spreadsheets, SQL queries, and Python scripts and still expect business users to trust the dashboards. To ensure data quality, reliability, security and freshness, you need a well organised set of tools and processes: a Data Platform. In this presentation, I will explain how the Data Platform at Flink was built, outline its high-level architecture, and describe the key products, tools, and processes that enable us to operate over a thousand data models and maintain full visibility into the current state of the business." **Sneha Nafade: *"AI Agents & Agentic Deployment"*** [Sneha Nafade](https://www.linkedin.com/in/sneha-nafade/) is a Cloud Architect at [Diconium](https://diconium.com/en/?utm_term=&utm_campaign=2025+%7C+Remarketing+%7C+DE/EN+%7C+All+Visitors&utm_source=adwords&utm_medium=ppc&hsa_acc=9083156072&hsa_cam=23281606208&hsa_grp=&hsa_ad=&hsa_src=x&hsa_tgt=&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=23483494785&gbraid=0AAAAADQqBJ6jY8TgZt7Ocjy37F5Gup62I&gclid=CjwKCAiAkbbMBhB2EiwANbxtbfuZyXSVyFENwFuHv9tAcygFWNM24hiXlk3rvKVpwBFfM__jFEBHBRoCMpsQAvD_BwE) with a rich experience in Cloud & Cybersecurity Architecture & Engineering.

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
