**RSVP via this link: https://www.meetup.com/nl-nl/codelabjug/events/312456204/?eventOrigin=group_events_list** **We’re happy to announce our next CodeLab!** Join us for a hands-on workshop: “Help! I Inherited Legacy Code – What Now?” What exactly is legacy code? Ask five developers and you’ll get five different answers – and none of them are wrong. In this workshop, we define legacy code as code without tests. Why? Because without tests, making changes becomes risky and error-prone. To refactor safely, we first need to build a solid understanding of what the code does, and write tests around it. This session explores practical techniques to make legacy code more testable and maintainable, so you can work with it more confidently. This workshop will be organized on-site in cooperation with the NS - Nationale Spoorwegen (Utrecht)! **Introduction:** During the workshop, you'll get hands-on experience with several techniques to bring legacy code under test. We'll also cover how to add new, tested features to untested codebases. The workshop blends practical exercises with theoretical principles from Michael Feathers' Working Effectively with Legacy Code. We’ll emphasize interaction, peer learning, and lots of space for discussion. **What you’ll learn (objectives):** * Understand what characterization tests are and how they can help * Learn techniques to break dependencies and isolate code for testing * Practice adding safe, tested features to legacy code * Give names to techniques you might already use instinctively, so you can better communicate about them * Gain confidence working in legacy systems without fear of breaking things **Who should attend?** Software developers (Java/Kotlin developers) who work with existing codebases and want to strengthen their legacy code handling skills. **What you’ll need:** Basic understanding of object-oriented programming and unit testing Your own laptop + charger Make sure you can build Java 17 with Maven (and that you are able to run unit tests) Recommended: IntelliJ IDEA. Other IDEs are welcome, but IDE-specific issues are your own responsibility ;-) **Agenda:** 16:00 - Walk-in & Food 17:00 - Start workshop 20:00 - End of the workshop 20:00-20:30 - Closing & Drinks RSVP via this link: https://www.meetup.com/nl-nl/codelabjug/events/312456204/?eventOrigin=group_events_list **Location:** NS - Nationale Spoorwegen Katreinetoren - 'De Kookstudio' Stationshal 17 3511 CE Utrecht Registration: A valid ID is required to enter the building

**Um was geht es dieses mal?** Dieses Mal haben wir zwei Talks für euch! **KI in der BIG direkt gesund - Von der Vision zur Realität - Stephan Rex (BIG direkt gesund)** BIG direkt gesund zeigt in dieser Präsentation, wie die strategische Einführung von Künstlicher Intelligenz im Unternehmen umgesetzt wird. Im Fokus stehen die Rolle des KI-Boards, das Architektur-Zielbild und die ersten praktischen Anwendungsfälle. Die Inhalte geben Einblicke in Erfahrungen aus Pilotprojekten und verdeutlichen, welche Faktoren für eine erfolgreiche Implementierung entscheidend sind. **F\*ck Feature Branches - Felix Fischer (codecentric AG)** Direkt auf Main pushen – das klingt ziemlich gruselig. Wie sollen wir nur ohne PRs und asynchrone, ineffiziente Code Reviews Kontrolle über unsere Kollegen ausüben? In diesem Talk werden wir die Geheimnisse des Trunk-Based-Development lüften. Wir wollen herausfinden, warum die angestaubten Wege der Software-Entwicklung hoffnungslos veraltet sind. Lerne durch Feature Flags, Dark Launches, synchrone Code Reviews und Pair-/ Mob-Programming Dich vom Drama der Feature Branches zu verabschieden! **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben.

This time, we will have a slightly different meetup than usual, as we want to gather some feedback about how we should shape the future of PHPAmersfoort. Should we continue as a PHP meetup, or switch to a broader topic such as web development? Should we continue with monthly meetups, or reduce the frequency to bimonthly or quarterly meetups? **Nic Wortel** will open the evening with a short talk about **What's New in PHP 8.5**, and then we will have a group discussion about the future of PHPAmersfoort. Once again the kind people at Enrise are opening their doors for us. 19:00 - Doors open 19:30 - **What's New in PHP 8.5** \- Nic Wortel 20:00 - **The Future of PHPAmersfoort** 21:00 - Social

#This meetup is around a third-party organizer (Focus Filmtheater): you can either purchase your ticket online or right before the session# **Title**: No Other Choice **Language**: Korean **Subtitles**: English **Length**: 139 min **Director**: Park Chan-wook **More info**: https://www.focusarnhem.nl/agenda/english-subs-no-other-choice/ **Ticket link**: https://www.focusarnhem.nl/tickets/141172/ **Synopsis**: *No Other Choice* is the new film by Park Chan-wook (*Oldboy*, *The Handmaiden*, *Decision to Leave*). The latest box office hit from South Korea combines black comedy and cinematic mastery in a sociopolitical thriller. After 25 years of loyal service, Man-su (Lee Byung Hun, Squid Game) loses his good job as supervisor of a paper factory when it falls into foreign hands. When finding a new job proves more difficult than expected, Man-su and his family are forced to drastically change their lifestyle. In a desperate attempt to come out on top at his next job interview, Man-su decides to eliminate the competition. How far will you go when there is no other choice? *No Other Choice* premiered at the Venice Film Festival and won the International Audience Award at the Toronto Film Festival. The Korean Oscar entry is on the shortlist for Best International Film. **How it works**: I will be at Focus around 18:30, where we can meet before the movie starts. You can message me to find us. Screening starts at 19:00. After the movie, we can have a drink together. Hope to see you soon!

We zien dat AI inmiddels door veel mensen en organisaties wordt gebruikt, vooral voor tekst, plannen en ideeën. Tegelijkertijd merken we dat dit gebruik vaak onzeker en oppervlakkig blijft. Mensen experimenteren, maar twijfelen: * Klopt dit wel? * Gebruik ik AI “goed”? * Haal ik er echt voordeel uit, of kost het vooral tijd? De kern van het probleem is niet een gebrek aan tools of kennis, maar een gebrek aan grip, overzicht en vertrouwen in het eigen oordeel bij het werken met AI. **Wat houdt deze workshop in?** We willen een kleinschalige pilot-workshop (halve dag) organiseren waarin we professionals helpen om: * AI anders te leren zien (als denkpartner, niet als antwoordmachine) * Bewuster vragen te stellen en context te geven * AI‑output te beoordelen in plaats van blind te volgen Het is nadrukkelijk geen technische training en geen overzicht van tools. Het is een leerervaring die zich richt op denken, beoordelen en professioneel gebruik. **Voor wie is dit bedoeld?** De Training richt zich op: * Niet-technische managers en professionals * Die veel werken met tekst, plannen en besluitvorming * Die AI al gebruiken (bijv. ChatGPT), maar daar nog te weinig zekerheid en rendement uit halen **Wat maakt deze aanpak anders?** * Interactief en herkenbaar: deelnemers werken met hun eigen praktijk en leren van elkaar * Beperkt en scherp: geen overload, maar drie kerninzichten * Veilig en menselijk: twijfel wordt genormaliseerd, niet weggepoetst Deelnemers weten na afloop wat ze “maandag anders doen” **Pilot2** Na een succesvolle eerste pilot op 16 januari hebben we weer verbeteringen anagebracht voor deze pilot. We verwachten dan ook eerlijke feedback om deze workshop nog gerichter in te kunnen zetten om professionals meer bewust te maken van de mogelijkheden en onmogelijkheden van AI. Deze workshop wordt verzorgd door Edgar Stormbroek en Ziryan Salayi 9:00 9:30 Inloop 9:30 - 12:00 AI in praktijk 12:00 - 13:00 Lunch 13:00 - 14:00 Vervolg AI in praktijk 14:00 - 14:30 Afronding en feedback

\*This event will be **ONLINE ONLY** **Are you an experienced tech professional aiming for top-tier roles at MANGA, AI companies, hedge funds or just the next step?** Your experience is solid, but is your CV holding you back? * CV doesn't bring you more interviews ? * Get ghosted often? * Recruiters don't move you forward once they review it? * 100 applications and less than 12 interviews (industry average) Top-tier tech companies receive thousands of applications from qualified candidates. At the senior level, it’s no longer just about listing your skills - it’s about how you frame your impact, leadership, and technical depth. We are bringing in a **Senior Engineer directly from Amazon** to provide insider insights on exactly what hiring managers at major tech firms look for in senior-level applications. **This is not a generic resume workshop.** This is a deep dive into crafting a CV that gets noticed by decision-makers at the highest levels of tech. **What We Will Cover:** * **The MAANG Lens:** How a Senior Amazon Engineer reads a resume * **Impact vs. Duties:** Shifting your CV language to highlight measurable business outcomes rather than just job responsibilities. * **Senior Positioning:** How to effectively structure leadership, architecture, and system design experience. * **The "Red Flags":** Common mistakes that get even highly experienced candidates rejected by ATS or recruiters. **Who Should Attend:** ⚠️ **Please Note:** This event is tailored for **experienced professionals** in the tech industry (e.g., Senior Software Engineers and tech professionals with more than 2 years of experience). **RSVP today to elevate your career prospects.** **Hosted by TopCoding**

### 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.
