We are excited to announce our next Utrecht JUG meetup on **April 20, 2026,** hosted at the **Kamer van Koophandel.** Join us for an evening focused on the future of software development, where AI-driven, agentic systems are becoming an integral part of how we build and operate applications. In the first session, **Soham Dasgupta** will demonstrate how AI agents can power autonomous DevSecOps pipelines; from detecting vulnerabilities to generating fixes and validating them through CI. This hands-on talk offers a practical look at building self-driving security workflows with tools like GitHub Copilot. After the break **Raphael de Lio** explores how memory works in both humans and AI agents. By connecting insights from cognitive science to real-world engineering challenges, this session sheds light on how to design more reliable and context-aware AI systems. Join us for an evening of practical insight, new ideas, and great conversations. Please join us and RSVP! Because of the limited number of seats, please keep your RSVP up-to-date, so we can welcome someone else if you can't make it. *** ## Timeschedule 17:00 Doors open 18:00 Food & Drinks 19:00 Agentic DevSecOps: Autonomous Security Pipelines with AI Agents & Agentic Workflows by Soham Dasgupta 20:00 Break 20:15 The Anatomy of Memory in Humans and AI Agents by Raphael de Lio 21:15 Drinks # Giveaway 1 JetBrains licence *** # Talks ## Agentic DevSecOps: Autonomous Security Pipelines with AI Agents & Agentic Workflows What if your security pipeline could find vulnerabilities, file issues, write fixes, run CI, and request human approval — all autonomously? In this hands-on session, we start with a polyglot microservices repo that has zero security tooling and progressively build a fully autonomous agentic DevSecOps pipeline using GitHub Copilot. You'll see how AI agents perform repo-wide security assessments, how custom instructions shape agent behavior across the SDLC, and how agentic workflows chain dependency scanning, SAST, and test coverage checks into a self-driving loop: scan → auto-create issues → Coding Agent fixes → CI validates → AI code review → human approves. We'll also build custom Copilot agents for IaC security scanning and use GitHub's agentic workflow capabilities to generate recurring security reports — no human trigger required. Walk away with a working, repeatable pattern for embedding autonomous AI agents and agentic workflows into every stage of your DevSecOps lifecycle. *** # The Anatomy of Memory in Humans and AI Agents Artificial intelligence does not need to copy the human brain to advance, yet cognitive science still offers useful guidance. As agentic applications grow, understanding how humans store and retrieve information can help us design agents that act with greater context and reliability. This talk connects human memory to the practical challenges of building AI agents with memory. We will review the main types of memory in the brain, revisit a landmark case in neuroscience, and relate these ideas to how large language models process information. We will also look at the real difficulties of taking agents to production, where choosing what to store and how to retrieve it becomes the core challenge. Participants will learn: \- How insights from cognitive science can guide agent design \- The key forms of human memory and their relevance to AI \- What neuroscience reveals about the limits of large language models \- The main obstacles of deploying agents with memory in real systems \- How our work at Redis led to an open\-source\, production\-ready agent memory server \- Practical ways to improve memory in AI agents This session offers both conceptual clarity and concrete tools for building more capable agentic systems. *** # Speakers ## Soham Dasgupta Soham is a technology enthusiast working at Microsoft as a Solution Architect, with over 19 years of experience in software programming, designing, and architecture which includes on-prem, cloud-native applications, and web-based conversational application design. *** ## Raphael de Lio Raphael De Lio is an AI and Software Engineer at Redis with over eight years of experience spanning multiple industries and countries. He is passionate about distributed systems and specializes in Java, Kotlin, and building scalable, high-performance software with a growing focus on reliable, distributed agentic systems. What drives him is bridging the gap between software engineering and AI engineering, bringing the hard-won knowledge of building distributed, scalable systems into the world of AI where those foundations are often missing but matter most. Originally from Brazil, Raphael spent six years in Portugal before making the Netherlands his home, where he also helps organize the Dutch Kotlin User Group. He loves blending code, community, and creativity to help developers build better systems faster, and with a lot more fun along the way.

Tijdens de maakavonden van Meet Je Stad soldeer je je eigen meetkastje dat temperatuur, luchtvochtigheid en fijnstof\* kan meten. Het solderen is geschikt voor iedereen: van beginner tot expert! Daarnaast bieden we begeleiding, dus hoef je niet bang te zijn dat je er niet uit komt. Ter deelname betaal je €15 voor de materialen. Vaak lukt het niet om al het soldeerwerk binnen één avond af te krijgen, maar dit is geen probleem; tijdens onze volgende maakavonden kun je langskomen om je werk af te maken. Inmiddels zijn er in de stad Utrecht nu zo’n 150 mensen die hun eigen meetkastje hebben gesoldeerd. Als je kastje af is wordt hij geregistreerd en kun je hem bij jou thuis ophangen/neerzetten. Hierbij krijg je instructies zodat je de juiste locatie kunt kiezen en je metingen zo betrouwbaar mogelijk zijn. Als het dan eenmaal hangt kun je via de kaart op de [website van Meet Je Stad](https://meetjestad.net/index3.php?loc=Tb) bijhouden welke metingen je kastje neemt: zo kun je bijvoorbeeld zien op welke momenten het bij jou het warmst is en vergelijkingen maken met waardes van andere meetkastjes. Dat kan door middel van [deze tool](https://mjs-datavisualisation-fez7kynngq-ez.a.run.app/) die je helpt om grafieken te maken. Dan kan je er achter komen hoe jouw omgeving ervoor staat in vergelijking met de rest van de stad. Meet Je Stad organiseert ook kennisavonden met gastsprekers die vertellen over hitte, fijnstof en andere burgerinitiatieven in de stad. Dit zijn ook gelijk geschikte momenten voor deelnemers om met elkaar in discussie te gaan over hun metingen en ondervindingen. Zo hopen we een netwerk van betrokken inwoners te creëren en meer te weten te komen over de milieuomstandigheden in de stad! *\*De fijnstofsensor is optioneel en kost 20 euro extra. Indien je deze bij je meetkastje wilt moet je deze via een draad met een stroombron binnen 15 meter kunnen verbinden.* **Organisatie:** Milieucentrum Utrecht (MCU) in samenwerking met de Makerscommunity HaHaHo. **Locatie:** Bibliotheek Neude, Huis van Actief Burgerschap (begane grond) **Kosten:** 15 euro voor materiaalkosten, 20 euro extra voor fijnstofsensor. (Meet-up suggereert bij het aanmaken van een account dat een betaald abonnement vereist is. Dit is niet zo, op de pagina waar gevraagd wordt om een abonnement te kiezen staat rechts bovenin de optie "Ga door met het gratis plan".) *Bij te weinig aanmeldingen kan de workshop afgelast worden.*

If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer. Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives. Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

A great ride along the Vecht and Gein rivers. You will love this route. Please ride single file along the winding river as there can be cars around each corner. **Route:** https://connect.garmin.com/modern/course/441606271 GPX: https://drive.google.com/file/d/17-T_pT_GH3QKSFcH1WWgfArvxSdAkVzO/view?usp=sharing **Afterwards:** Drinks at Polder https://maps.app.goo.gl/tbt5DDG7YLU3uWvaA **Rules:** \- Download the route to your cycling computer so you can always find your way home \- Make sure to arrive on time \- Before you ride\, decide as a group how you want to ride: you can split up in a fast and a slow group or stay together\, but make sure to discuss what pace you are going to ride and whether you are going to wait if someone is slower than the group\, or not\.

**For this series you need to register via our website:** https://www.maitreya.nl/nl/programma/db-module-9-samsara-and-nirvana-4/2026-04-13. This is a module in the foundational Discovering Buddhism Series with Annelies van der Heijden (at our center and online). **Samsara & Nirvana** Investigate what “samsara” is and how we are stuck in it. Find out what “nirvana” is and how to achieve it. All living creatures know suffering—this is the Buddha’s first noble truth. And many of us also know how ordinary pain can grow into extraordinary suffering due to the power of our minds. In Buddhism, these negative states of mind that lead to suffering are called delusions. They are a primary cause for us being stuck in samsara—the cycle of endless rebirths that ordinarily propels one’s mind toward more suffering. The good news is that complete liberation from the suffering of an afflictive mind (nirvana) is entirely possible. Explore the meaning of samsara and nirvana with Annelies, and learn how to move out of a state of inevitable suffering to one of pure and irreversible peace. Find out how to develop your own determination to be completely free from suffering (renunciation) and its role on the spiritual path. Get empowered with practical tools for dealing with disturbing emotions up to the point of elimination, and reflect on the possibility of nirvana––and how that differs from enlightenment.

**📣** Welcome to **our second meetup in 2026!** Missed last meetup? Then its important you know that the Green Software Foundation and Sustainable IT Netherlands meetups, merged into one: **Sustainable IT Action NL!** Our mission is still to build connections around sustainable IT, exchanging ideas in a space for learning - and from there inspiring our members to take action. **🌿** We’re excited to gather peers who care about green, efficient, and responsible cloud practices on **April 23rd**, kindly hosted by **GreenPT** in Utrecht. **⏳ Time schedule** 17:30 – 18:00 Welcome 18:00 – 18:30 Vegetarian bites & networking 18:30 – 18:45 Kick-off & community introductions 18:45 – 19:15 Measuring the environmental impact of Google's AI - interactive explainer – Ozan Ogreden 19:15 – 19:45 Maryse Meinen– Holistic Digital Sustainability 19:45 – 20:00 Pitches 20:00 – 20:45 Drinks & networking **📍** 📍 **Location:** Plompetorengracht 4, Utrecht. GreenPT **❗ Capacity is limited to 50 participants, so please register early.** **✏️ Title: Measuring the environmental impact of Google's AI - interactive explainer** **💡 Speaker: Ozan Ogreden** **🍃 Abstract:** I built an "interactive explainer" that reproduces Google's methodology from Elsworth et al. (Measuring the environmental impact of delivering AI at Google Scale, Aug 2025, https://arxiv.org/abs/2508.15734). I'd like to share the explainer and my observations with the community. What stands out to me is a striking analytical (or rhetorical?) choice by Google team, which seems to be leading to a downward bias in headline-reported figures of their work. With the community, I'd like to attempt at two goals. One of them is a "narrow-minded goal", trying to find a charitable interpretation of what may have motivated Google's choices (specifically in the discussion related to measuring environmental impact of LLMs). The second is a goal with a more important perspective: Given our discussion, what's the best use of our time to move the needle in sustainable IT? *Ozan works at GreenPT:* GreenPT is a GPT-powered chat platform, and robust API, trusted by governments, businesses, privacy-focused organizations, and developers. Running on renewable energy and hosted in Europe for strict data protection, GreenPT gives you and your team the answers you need with a clear conscience and total transparency. [https://greenpt.com/](https://greenpt.com/) **✏️ Title:** Holistic Digital Sustainability **💡 Speaker:** Maryse Meinen **🍃 Abstract:** Less is More! This interactive session brings you inspiration and practical tips for embedding more sustainability all throughout your digital Product Development Cycle!
