Join our inspiring "Success Team"! We will be at the cosy Rosa Buurtcentrum (2nd floor–eerste verdieping–right hand, last door; there is a lift). There will be very hot tea and you are welcome (but not required) to bring snacks. –See you then! \*\*\* Help wanted & help offered. Bi-weekly meetings (every two weeks). Language English/Dutch. This idea is inspired by Barbara Sher's story and experiences. Please see her Ted Talk titled "Isolation is the dream-killer, not your attitude". The idea in short: One person at a time tells the group his/her dream or aim and the obstacles they face to achieve it. It could be a trip, an experience, a change of career, an undertaking of some kind, learning a skill, solving a particular problem or even finding out what you really want. The group works to realise the person's aim. Not just theoretically, also practically. For this we use our experience and networks. —Nothing as satisfying as helping another! Perhaps suitable, Gabor Mate's words: "You never heal alone." Please contact me at galatv@protonmail.com if you have questions or would like to help me to organise these gatherings. Thank you!

This meetup will be hosted by Xebia, in their office at Wibautstraat 200, 1091 TJ Amsterdam, Netherlands. **Note:** There are no parking options at Xebia itself, though there are (paid) parking garages available nearby accessible via the Parkbee app. **Agenda** **18:00** Doors open and food **18:55** Intro **19:00** [Susanne Pieterse](https://www.linkedin.com/in/susannepieterse/) presenting “RAG in the Wild: Real-World Lessons from Modernizing Legacy Systems” **19:45** Break **20:00** [Kubilay Karpat](https://www.linkedin.com/in/kubilay-karpat/) presenting: "Coroutines Under the Hood: How Suspend Actually Suspends" **20:45** Closing drinks **21:00** End **Information about the talks:** **Title: "RAG in the Wild: Real-World Lessons from Modernizing Legacy Systems"** Enterprise and government document systems hold terabytes of valuable unstructured information, yet most still rely on keyword and metadata search with little semantic context. Retrieval-Augmented Generation (RAG) promises a breakthrough, but tutorials rarely prepare you for regulated, large-scale environments. In this talk, I’ll share lessons from building a RAG stack with Spring Boot, Elasticsearch, LangChain4j, Docker, and ActiveMQ, using both Azure OpenAI and Ollama. Expect concrete insights on document chunking, enforcing access control, and keeping LLMs grounded in facts — practical takeaways for anyone bringing RAG from demo to production. **About Susanne Pieterse.** Susanne is an auto-didact full-stack software engineer and iSAQB certified software architect. Passionate about creating innovative solutions and sharing knowledge. Loves tea and a heavy bag boxing workout. **Title: "Coroutines Under the Hood: How Suspend Actually Suspends"** We use suspend functions regularly, but few of us stop to ask how they actually work. In this talk, we’ll follow the evolution from callbacks to reactive programming, and finally to Kotlin coroutines — showing how suspend brings async to the language level. We’ll peek under the hood to see how suspension really works, how Kotlin compiles suspend functions into state machines, and why this model scales so well. This talk is for anyone ready to uncover what truly makes Kotlin’s async feel so effortless and powerful. **About Kubilay Karpat.** Kubilay is a software consultant at Xebia, where he helps teams build efficient and maintainable backend systems using Kotlin. He’s passionate about software architecture and enjoys looking at problems through the lens of different languages and paradigms, drawing on experience with Go, TypeScript, Python, and Java. He shares his learnings through workshops and community events. Lately, he’s been exploring how Generative AI can support developers across the stack. In his free time, he travels with his wife, though their vacations are so packed they usually come home needing a vacation from the vacation.

Some people talk about politics. Others can't stop talking about fishing. I can continue talking forever about org design... Join me in Utrecht to talk about #OrgDesign! #OrgTopologies

'THE THURSDAY MURDER CLUB' by Richard Osman 'Smart, compassionate, warm, moving and so VERY funny' Marian Keyes 'So smart and funny. Deplorably good' Ian Rankin 'Thrilling, moving, laugh-out-loud funny' - Mark Billingham In a peaceful retirement village, four unlikely friends meet up once a week to investigate unsolved murders.

This meetup is your chance to discuss the future, share ideas, and network with pioneers in the decentralized money world. 🏢 **Central Location**: café Sint Pieter ligt perfect centraal, een ruim cafe op de grote markt van Turnhout. Mark your calendars and spread the word!

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
