## Sandboxed Agents with yoloAI Hello, 世界! For meetup #59 on Tuesday [Apr 28, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537718/) we are thrilled to welcome back [Karl Stenerud](https://www.linkedin.com/in/kstenerud/), who will be presenting (remote) one of his recent projects: [yoloAI](https://yoloai.dev/): > Run AI coding agents freely in a disposable sandbox. Review exactly what changed. Apply what you want. Some people are aware of the security nightmares that probabilisic language models with full system access may have, but you also need to act on it. > Permission fatigue is a real problem. Sandbox escape is a real problem. yoloAI solves it. The project is written in Go and open source at [kstenerud/yoloai](https://github.com/kstenerud/yoloai), works with various sandbox backends like docker, podman, tart, seabelt - and security modes, using [runc](https://github.com/opencontainers/runc), [gvisor](https://gvisor.dev/), [kata](https://katacontainers.io/), [firecracker](https://firecracker-microvm.github.io/). After looking at a agent memory upgrade system in [#58](https://golangleipzig.space/posts/meetup-58-wrapup/), we continue our exploration of [agentic coding](https://missing.csail.mit.edu/2026/agentic-coding/) and ai assisted software development, which is a rapidly developing field. ### Schedule * 18:45 Doors open * 19:00 Welcome * 19:10 yoloAI (remote presentation) * 20:00 Open discussion We’ll meet: * in person at [Basislager Leipzig](https://basislager.co), at [Peterssteinweg 14, 04107 Leipzig](https://maps.app.goo.gl/1fMkeDSPZ7Aauszh8) ([OSM](https://www.openstreetmap.org/node/3504864558)) * and online via [Google Meet](https://meet.google.com/tgb-juwg-khy) Join us to discuss security, agents, isolation techniques and more.

Wir laden zum nächsten Meetup ein. Diesmal definitiv hybrid und mit einem tiefen in die Praxis moderner KI-Entwicklungen. Im Mittelpunkt steht ein Erfahrungsbericht von **Hans Brender (MVP)**. Er gibt Einblicke in die Entwicklung einer Lösung für die elektronische Patientenakte **(ePA)**. Von den ersten Architekturideen bis zur Umsetzung im realen, hochsensiblen Umfeld. Ein besonderer Fokus liegt auf die Modell-Reise von ChatGPT über DeepSeek bis hin zu Mistral AI und der Frage, warum dieser Weg genau so verlaufen ist. Wir sprechen unter anderem über: * **Modell-Evolution:** Warum führte der Weg von ChatGPT über DeepSeek letztlich zu Mistral AI? * **Gründe & Hürden:** Welche Entscheidungsfaktoren spielten eine Rolle und welche Herausforderungen bracht die ePA mit sich? * **Praxis-Check:** Was funktioniert im Alltag wirklich und was stößt an klare Grenzen? Wie immer lebt das Meetup vom offenen Austausch. Fragen, eigene Erfahrungen und Perspektiven sind audrücklich willkommen. Egal ob zu Claude, Gemini, Copilot oder zur Integration von KI in bestehende System. Wir freuen uns auf einen gemeinsamen Abend bei uns in Schwabach!

We are delighted to invite you to our hybrid (virtual and onsite RSVP available) April gathering at [Ojin AixHaus in Mitte](https://ojin.ai/community). We’ll be unpacking the top highlights from Google Cloud Next '26 its 22-24 of April [(register to get virtual spot)](https://www.googlecloudevents.com/next-vegas/) and sharing expert insights on the Agent Development Kit. **The Agenda** * 6:00 pm: Doors open for snacks, drinks, and a bit of a chinwag * 6:45 pm: Kick-off with the Ojin AixHaus crew * 7:00 pm: Google Cloud Next '26: The highlights! * 8:00 pm: [Iliyan Peychev](https://www.linkedin.com/in/iliyanpeychev/): Evolving Cloud Run Apps into Agents with ADK *Agents are here to stay, and Google’s ADK makes building them from scratch more accessible than ever. But in the real world, we rarely start with a blank slate. What if we have battle-tested Cloud Run applications already using Gemini that we need to evolve? How can we get the benefits of the Agentic world without a full rewrite? This session focuses on moving from manual controllers and service orchestration to Multi-Agent systems with Google’s ADK. We will explore the practical "why" and "how" of this architectural shift, along with the real-world caveats and pitfalls.* * 9:00 pm: 🍕🍻 Rooftop Drinks & Networking (with a view!) * 10:00 pm: Doors close **🙏 Thanks & Credits** A massive thank you to **[Ojin AixHaus Community ](https://ojin.ai/community)**crew for letting us in their brilliant space! **Follow Ojin AixHaus on socials: [Instagram ](https://www.instagram.com/ojin.ai/#)[Lin](https://ojin.ai/community)[kedin ](https://www.linkedin.com/showcase/ojin-aixhaus/)[X](https://x.com/Ojin_AI)** We’d love to see you there! ***

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

Dear Illinois Prairie PUG members, Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes. Our new meeting place is **Chicago Innovations at 1 W. Monroe**. *Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres *Speaker*: Elizabeth Christensen, Snowflake *Talk Description* The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris. *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:20 - Hettie D. Data warehouse history overview 6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres 6:50 - 7:00 Q&A 7:00 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. You will notice the change in the RSVP form. We are thankful to our hosts and promise to be responsible. We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). We do not want to waste food, so please indicate your dietary preferences. We will not close the RSVP in the morning of the meetup, but please do your best to RSVP in advance so that we can order the appropriate amount of food and drinks. Also, all meetups will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.

It feels like we just saw each other 🤷. Join members of the local design and UX community for our monthly breakfast. For May we’re stopping in for Rooh’s popup breakfast/cafe concept. You know someone is getting the lobster yuzu croissant, and that’s not even the prettiest thing on the menu!.

You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA). AoC members are invited to join this OA meetup and/or OA Facebook group ( https://www.facebook.com/groups/omnipresentatheists/ ) but are free to continue conversations on the AoC Facebook group ( https://www.facebook.com/groups/columbusatheists/ ). AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge. Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org). Omnipresent Atheists is a member of the Columbus Coalition of Reason ( http://www.ColumbusCoR.org ). Omnipresent Atheists endorses the mission of the Secular Coalition for America ( http://secular.org ).
