Nutritional Cleansing

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.

Give your still good laptop a second life instead of ditching it because Windows 11 says it is no good... Or you heard Linux is cool. If you have a backup of your data, that is great, else indicate that you do not, so we can help you. Do so in an extra message or to m10@m10tech.nl, else I don't receive your information. Geef je laptop die het nog prima doet een tweede kans in plaats van hem af te schrijven omdat Window 11 dat zegt... Of omdat je hoorde dat Linux gaaf is. Als je al een backup van je data hebt gemaakt is dat perfect. Of verwacht je dat wij dat doen? In dat geval graag aangeven hoe vol je harde schijf nu is... Doe dat in een extra bericht of aan m10@m10tech.nl, want de info komt anders niet door.

**Bitcoin Meetup met Crazy Pool!** Deze maand organiseren we iets leuks: voorafgaand aan de meetup (voor wie dat wil) spelen we Crazy Pool bij Timestamp op de Korenmarkt. Crazy Pool lijkt op minigolf, maar je speelt het met een keu en een bal die je door verschillende obstakels moet stoten. De speeltijd is ongeveer 45 minuten. Aansluitend eten we bij Flor Fina. Je kunt ook na het diner aansluiten als je alleen voor een drankje wilt komen. De Bitcoin Meetup is geschikt voor zowel beginners als ervaren bitcoiners. Stel je vragen en praat mee over de nieuwste ontwikkelingen in de wereld van bitcoin. Wil je meedoen met Crazy Pool of mee-eten? Laat het ons even weten, dan houden we daar rekening mee bij de reservering. * 16:30 — Crazy Pool @ Timestamp (Korenmarkt) * 17:30 — Diner @ Flor Fina (Korenmarkt) * 19:30 — Drinks @ Flor Fina (Korenmarkt) ## English Bitcoin Meetup with Crazy Pool! This month we’re doing something fun: before the meetup (for those who want to join) we’ll play Crazy Pool at Timestamp on Korenmarkt. Crazy Pool is similar to mini golf, but you use a cue to strike a ball through various obstacles. Playtime is about 45 minutes. Afterwards we’ll have dinner at Flor Fina. You can also join later if you only want to come for drinks. The Bitcoin Meetup is suitable for both beginners and experienced bitcoiners. Ask your questions and join the conversation about the latest developments in the world of bitcoin. Would you like to play Crazy Pool or join us for dinner? Please let us know so we can account for it when making the reservation. 16:30 — Crazy Pool @ Timestamp (Korenmarkt) 17:30 — Dinner @ Flor Fina (Korenmarkt) 19:30 — Drinks @ Flor Fina (Korenmarkt) ## Deutsch Bitcoin Meetup mit Crazy Pool!

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 7:00pm on Wednesday, April 22 at Streetlight Guild. 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:** 6:45ish - Quick introductions 7:00 - Timer starts: write for 1 hour 8:00 - The End **OPTIONAL SOCIALIZING** happens before and after the writing hour. 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! If you were on time, please be willing to make room for the friendly latecomer. Happy writing & I look forward to seeing you at Streetlight Guild! **WHAT SHOULD I BRING?** Whatever you need to be able to write! You're welcome to bring earplugs/headphones if noise will bother you! **OTHER IMPORTANT DETAILS:** * **RSVP:** Please RSVP by 6:00pm the evening of the meeting. This helps me know how many to expect, and if we'll need additional space! * **COVID:** While masks are not required, please be mindful of the other writers around you and their comfort levels. * **WIFI/OUTLETS:** Outlets are limited, so please ensure your devices are charged when you come! But Streetlight Guild does have free WiFi! Yay! * **PARKING:** There is free public parking at Streetlight Guild.
