Leipzig Gophers #59 - Sandboxing Agents with yoloAI
## 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:

Dzień otwarty, bez tematu przewodniego
Hakierspejs spotyka się na żywo w siedzibie stowarzyszenia! Zapraszamy wszystkich zainteresowanych naszą aktywnością. Uczestnictwo jest darmowe, rejestracja nie jest obowiązkowa – wystarczy po prostu przyjść. Nie mamy żadnego konkretnego planu: po prostu zbieramy się i haczymy - co komu przyjdzie do głowy.

CTF-y z Hakierspejsem
Spotkania z serii wymiany wiedzy podczas wspólnego rozwiązywania zadań CTF – jest to świetna zabawa pozwalająca równocześnie rozwinąć wiedzę w zakresie cyberbezpieczeństwa. Poziom trudności CTF-owego zadania ustalimy na początku spotkania. Najprawdopodobniej wybierzemy coś z platformy Hack The Box. Spotykamy się **co tydzień w środę o 19:00.**

Planszówkowanie w Hakierspejsie
Zapraszamy na kolejne spotkanie planszówkowe!
Mamy parę gier w spejsie, ale zachęcam przynieść również własne gry! Chętnie zagramy w coś nowego. Jest też miejsce na zostawienie gier na jakiś czas w spejsie, żeby nie musieć ich targać tutaj co tydzień.

Cloud Next '26 & Rooftop Networking: Building Agents with ADK @ Ojin AixHaus
Complete your event RSVP here: [https://gdg.community.dev/events/details/google-gdg-cloud-berlin-presents-cloud-next-26-amp-rooftop-networking-building-agents-with-adk/](https://gdg.community.dev/events/details/google-gdg-cloud-berlin-presents-cloud-next-26-amp-rooftop-networking-building-agents-with-adk/)
Hi.
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
