Make New Friends

Hi✋ At[ Data Tribes ](https://www.datatribes.nl/)we organise Meetups because we truly care about sharing knowledge both inside and outside the organisation. We believe that it is beneficial to us and to the market as a whole to connect, create, learn and grow together! **The agenda** // Doors open 6.00pm // Drinks and Pizza’s 6.30pm // Start presentations 7.00pm // Guest Speaker Advait Avinash Sowale // Quantifying the Impact of Data Quality on AI-Driven Decision Accuracy // Start networking 9.00pm // End Meetup 9.30pm Greetings, Data Tribes Inc.

**ArnhemJUG** We are excited to announce that we are welcomed by Entrnce for the April meetup. **Agenda** * 17:00 CET walk-in * 17:30 – 18:30 Food and drinks * 18:30 – 19:30 talk: **Better Assertions with AssertJ** by **Tim te Beek** * 19:30 – 19:45 break * 19:45 – 20:45 talk: **Reproducible Builds with Apache Maven** by **Hervé Boutemy** * 20:45 – 21:30 drinks **Better Assertions with AssertJ** Not all testing libraries are equal. Sure they all run your tests, but what happens when they fail? “Expected ‘true’, was ‘false’” won’t help you much. Your choice of library determines whether you can immediately jump to a fix, or first have to debug for more details. And with JUnit 6 and AssertJ 4 around the corner, it's high time for an upgrade! In this talk we'll explore AssertJ, and the fluent assertions API it provides. We'll contrast this to alternatives like JUnit and Hamcrest, and show how subtle differences improve the experience. Now you can finally have unified fluent assertions for all your tests, with a clear path to get there. For existing AssertJ users we will optimize its use to get more expressive assertions and meaningful messages from existing tests. Finally, a quick few OpenRewrite recipes help you apply all these best practices at once, and continuously going forward. **About** **Tim te Beek** Tim te Beek is a staff software engineer at Moderne, which automates software refactoring at scale. He has extensive experience contributing to and presenting on Open Source software within the Java ecosystem. Previously he worked as a consultant specializing in migration engineering and developer productivity. **Reproducible Builds with Apache Maven** Reproducible Builds is listed as a requirement for SLSA security Level 4, to achieve the highest level of confidence and trust in software. Such a level seems far away from achievable practice for normal humans. In reality, most Linux distributions implemented it over the last 10 years. And in the past 6 years, this practice is being extended to Java Open Source projects with great success: more than 6,200 releases from 800 Open Source projects published to Maven Central are publicly proven reproducible (and counting). In this session, we'll demystify Reproducible Builds for Java based on the experience gained while rebuilding these Open Source projects. We'll dig into the tools to improve your Maven builds and check the effective results: the journey is full of great learnings that go far beyond advanced security. **About Hervé Boutemy** Hervé started with Java when it was in beta, built his first Java projects with Make (yes) then Ant: but life changed with Maven 1... Life changed even more when growing from OSS user during working day to becoming an active OSS contributor to Maven 2 during nights and week-ends. Today, Hervé works as Solutions Architect for Sonatype on next steps of the build journey, promoting best-practices around Software Supply Chains. On the OSS front, Hervé is an Apache Software Foundation member and Apache Maven PMC Chair. He's also involved in many advanced projects like CycloneDX, SPDX, sigstore, and Reproducible Builds.

We normally design interventions to improve our organizations. What if we flip the script, try to break it, and see how hard that is from the other side? This workshop makes these dynamics visible through game mechanics and shifts perspective by asking a provocative question: "*If you wanted to deliberately ruin this company in the next few years and nobody should explicitly know that this was your plan, what would you do?*" As the "*evil management team*", you get to try to ruin a fictional company and experience the pushback and resistance from the organization, because it wants to stay alive. The game is designed using systems thinking (with a focus on long-term effects) and the 3rd Entity concept from ORSC. In small groups, players receive a short fictional company profile and play through several rounds of "*destructive executive decisions*": strategy shifts, structural changes, policy tweaks, talent moves. During the game, players get to act from the company's perspective as well. This way, we explore how the system adapts, compensates, or even uses the damage to strengthen itself, drawing on ideas from complex systems and organizational inertia. A playful, creative simulation-based workshop with a fresh perspective on the complexity of change in large structures. You will gain a sharper sense of the system's resilience and the different forces involved in change by performing for all the sides involved in or affected by the change. **Come and join the fun.

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at Factor-ij Amsterdam on Thursday mornings. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 11: 15 AM - Quick introductions 11: 30 AM - Timer starts: write for 1 hour 12: 30 PM - The End: chat, take off, or keep writing OPTIONAL SOCIALIZING happens at 12:30 pm after the writing is wrapped. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. (I’ll be the person with the Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you at Factor-ij! What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons. Please come with your devices pre-charged, since we probably won't be always sitting somewhere with charging possibilities. Other Important Details: Travel by public transportation: 1. Take Tram 26 from the central station Amsterdam, and step out by the last stop. 2. Take bus 66 from the Amsterdam Bijlmer station, step out by Pieter Oosterhuisstraat, and further walk in the direction of the bus till the corner. FREE Wifi. Compulsory consumption is not required, but please do order a drink to honor our generous host.

'CONVENIENCE STORE WOMAN' by Sayaka Murata 'Keiko Furukura had always been considered a strange child, and her parents always worried how she would get on in the real world, so when she takes on a job in a convenience store while at university, they are delighted for her. For her part, in the convenience store she finds a predictable world mandated by the store manual, which dictates how the workers should act and what they should say, and she copies her coworkers' style of dress and speech patterns so that she can play the part of a normal person. However, eighteen years later, at age 36, she is still in the same job, has never had a boyfriend, and has only few friends. She feels comfortable in her life, but is aware that she is not living up to society's expectations and causing her family to worry about her. When a similarly alienated but cynical and bitter young man comes to work in the store, he will upset Keiko's contented stasis--but will it be for the better? Sayaka Murata brilliantly captures the atmosphere of the familiar convenience store that is so much part of life in Japan. With some laugh-out-loud moments prompted by the disconnect between Keiko's thoughts and those of the people around her, she provides a sharp look at Japanese society and the pressure to conform, as well as penetrating insights into the female mind. Convenience Store Woman is a fresh, charming portrait of an unforgettable heroine that recalls Banana Yoshimoto, Han Kang, and Amélie.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.

We’re bringing back Adult Field Day. Last year was a good mix of competition and just hanging out, so we’re doing it again with some new games mixed in. Think team-based challenges, simple races, and a few things inspired by game shows. You don’t need to be athletic. Most of the fun is just being part of a team and getting to know people you wouldn’t normally talk to. The goal isn’t really winning. It’s meeting people, laughing a bit, and leaving knowing a few more names than when you showed up. If you stick around after, we’ll have a potluck, a bonfire, and a couple comedians in the evening. Bring: * Please Bring Something to share for the potluck cookout signup sheet [https://www.signupgenius.com/go/10C0E49ABA92EA2FAC70-63781787-saturday](https://www.signupgenius.com/go/10C0E49ABA92EA2FAC70-63781787-saturday) * Clothes you can move around in RSVP on Meetup is free. A small contribution helps keep events sustainable and ensures those who RSVP actually show up. Great events take time, effort, and consistency to organize. Most people contribute $2–5 per event to help keep these going. Appreciate everyone who supports — it genuinely makes a difference. If you find value in these events or maybe even made a new friend, consider contributing what feels fair to you. **Contribution link** listed below in the comments
