Let's meet at the CNC meetup on Thursday, May 21st, 2026, at 15:00 CET. **Location:** VSHNtower, 8th floor, Neugasse 10, 8005 Zürich **Agenda:** Would you like to speak at this event? Contact us at [https://cnc-meetup.ch](https://cnc-meetup.ch)! Guidelines: * All sessions are held in English. * No product or sales pitches are allowed. * All projects showcased should be open source. * We cannot cover travel costs, but we welcome speakers from other regions. * We're seeking more diversity among our speakers: underrepresented groups are welcome! 14:30 – Door Opening 15:00 – Welcome, Intro, & Announcements 15:05 – Kuberik: Safe, Hands-Off Deployments for Kubernetes (Luka Rumora) 15:35 – 5 minutes pause 15:40 – Kubernetes Without the Operator: A Minecraft Panel with Rust and kube-rs (Hadi Cherkaoui, CM Informatik AG) 16:10 – 5 minutes pause 16:15 – Vibe Code Survival Guide for Open-Source (Vadim Bauer, 8gears) 16:45 – 5 minutes pause 16:50 - Writing a Kubernetes Cluster Autoscaler Provider with externalgrpc (Marco De Luca, VSHN) 17:20 – Final words, networking & apéro Kuberik: Safe, Hands-Off Deployments for Kubernetes (Luka Rumora) Most teams deploying to Kubernetes end up in one of two places: either GitOps that stops at applying manifests, or brittle CI pipelines full of bash and glue. Both fall short of true end-to-end delivery. The ideal is well known—canaries, health checks, smoke tests, promotions, rollback—but Kubernetes lacks a native, reusable way to compose these without reinventing everything. Existing tools solve pieces (Argo Rollouts, Flagger, Kargo), but not the whole pipeline. Kuberik fills that gap: it orchestrates the full journey from release to production—detecting, gating, rolling out, verifying, and promoting—using opinionated, pluggable Kubernetes resources that integrate with existing GitOps setups. Luka is a Lead SRE with 10 years of experience building platform infrastructure and internal developer tooling, always with the same focus: systems that are robust, easy to maintain, and a pleasure to use. Over the years, he has watched the delivery tooling landscape change, from Jenkins to GitLab CI to Drone to GitHub Actions, yet the fundamental approach to CD has stayed the same: step-based pipelines with the same challenges they had a decade ago. He built Kuberik because he believes we can do better. Kubernetes Without the Operator: A Minecraft Panel with Rust and kube-rs (Hadi Cherkaoui, CM Informatik AG) Anvil is a Kubernetes-native Minecraft server panel written in Rust. It creates one StatefulSet, PVC, and Service per server through direct kube-rs calls, with no CRD and no controller. The Kubernetes API itself is the runtime state store; every user action is a direct API call. This 20-minute talk argues that the operator pattern is sometimes the wrong tool. Controllers earn their complexity when there's autonomous state to reconcile. They become a ceremony when there isn't. Anvil is a worked example of the imperative alternative, running on a home lab k0s cluster. Hadi Cherkaoui is a 17-year-old EFZ Plattformentwickler apprentice at CM Informatik AG in Schwerzenbach, ZH. He works daily with k0s and FluxCD, and is interested in Kubernetes, Rust, infrastructure automation, and homelab projects. Vibe Code Survival Guide for Open-Source (Vadim Bauer, Container-Registry.ch) Vibe code is flooding open-source projects with an ever-growing volume of pull requests and ideas. Banning AI contributions isn't the answer, yet it is difficult to resist. How can open source projects survive and keep progressing despite the pressure? This talk covers the project playbook we're building in CNCF Harbor and Harbor Satellite: defining a clear project direction so contributors, human or AI-assisted, know what's in scope before they contribute. Setting explicit acceptance criteria and guardrails. Using AI on the maintainer side to triage, review, and filter the growing volume of contributions. Deciding as a project where your boundaries are, what's core, what's an extension, and what's out of scope, so you stop drowning in well-intentioned feature PRs that slowly erode coherence. We share what works, what fails, and how we are rethinking open-source, contributions, community, and project Vadim Bauer is a Container Silverback with over a decade of experience in running containers in production. As a maintainer of the CNCF project Harbor, he focuses on extending the boundaries of OCI artifact management, adoption, and developer experience. At 8gears, Vadim helps cloud providers, ISVs, and enterprises adopt Harbor and use OCI capabilities. Writing a Kubernetes Cluster Autoscaler Provider with externalgrpc (Marco De Luca, VSHN) The Kubernetes Cluster Autoscaler decides when to scale, but it doesn't know how to create a VM. That's the cloud provider's job, and the upstream tree covers mostly big clouds. With externalgrpc, you can plug virtually any cloud into the autoscaler over gRPC. This talk first looks at how the Cluster Autoscaler works under the hood and where the cloud provider fits in. Then we walk through implementing one for a Swiss IaaS provider as an out-of-tree gRPC service: the design choices, the parts of the contract that matter, and the gotchas you only find by reading the autoscaler source. By the end, you'll know how to attach autoscaling to a cloud that isn't on the upstream list. Marco De Luca is a software/infrastructure engineer at VSHN AG. He spends most of his time on Kubernetes platforms, developer tooling, and making sure things don't break at 3 AM. At mdnix.io, he writes about infrastructure, Linux, Kubernetes, and the things he builds along the way. When he's not behind a terminal, he's somewhere in the Alps with his camera or having a private jam session with his guitar. The event will be recorded and made available on VSHN's YouTube channel: [https://vshn.tv](https://vshn.tv). Subscribe to stay notified of updates.

Dear All, This session is mainly for the people who want to learn kundalini yoga/meditation in a traditional way. Traditionally the master will transfer his/her kundalini energy to the student to activate his important chakras (energy centre) including Third Eye and Crown Chakra. The student can start to feel his/her Kundalini Energy is rising from their base of the spine and feeling the energy vibration(Consciousness) in the third eye (the space between the eyebrows) from the Kundalini Activation. This session is helpful for the beginners who want to learn simple yoga-meditation exercises also. This is a general session to experience your inner kundalini energy. But if you need proper kundalini activation(Shaktipat), then pre-registration is mandatory. **What is included in this session?** Simple stretching practices for Hip and Spine (not complicated, even beginners can do) Kundalini Breathing Techniques Sound Energy (Mantra) Meditation Energy Healing Techniques Formal Kundalini Activation (optional and only for pre-registered people) Chakra Meditation Yoga Nidra (Relaxation) **Some of the benefits of Kundalini Energy Activation are:** Keeps the body healthy Mind attains its natural peaceful state, so the meditation becomes easy. Breathing pattern will be harmonized Stress release and peace Clear & sharp intellect More intuition Inner happiness Clairvoyance and Clairvision and to the ultimate SELF realization (which will lead to the blissful state - our true state) with enough years of practise **DONATION BASIS** **About the Teacher who conducts this session:** The kundalini wisdom teacher Jayaprakash is practising kundalini yoga since 2005 under the guidance of Self Realized Indian Master "GuruMahan". He is teaching kundalini yoga since 2008 as part of a non-profit organization "Maha Shakthi Yogam Switzerland". He teaches Yoga/Meditation/Pranic Healing/Stress Relief courses in various places of Germany and Switzerland. He is the authorized kundalini yoga wisdom teacher from UPF(India) to give kundalini initiations (Shaktipat) with the Grace and Protection of his Master. All these events are conducted for non-profit purpose. Donations are collected on behalf of Swiss non-profit organization (Verein) "Maha Shakthi Yogam - Switzerland" **Eligibility:** Anyone can attend the session even if they don't have previous yoga/Meditation experiences. **Dress:** Wear a comfortable dress if possible yoga dress. We provide the yoga mat. **Please RSVP only you are really interested and coming ! Limited Seats !** **About Kundalini Shaktipat:** In every human being there is a source of natural energy that the yogis call the kundalini. In order to evolve in the yogic path, no matter what our path, the kundalini must be active. For most of us, the kundalini lies dormant at the bottom of the spine in the base chakra known as the Muladhar. When it awakens, it ascends through the chakras until it reaches the highest chakra, the Sahasrar. When that occurs, we merge with our True Self and attain SELF realization (our true nature). Shaktipat is the transfer of spiritual energy from the teacher to the student in order to awaken the kundalini. This process is compared to lighting one candle with another that is already lit and glowing. When the teacher is connected with the fully realized master and the energy is completely within his or her control, shaktipat initiation ensures that the student’s energy will remain active and stable. "Electricity is present everywhere, but there can be light only when the switch is turned on. Similarly the true master manifests the consciousness in the disciple through shaktipat.” **HAPPINESS is our TRUE Nature, which comes from within not from outside !**

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

**Building a great product is one thing—building momentum behind it is another.** Join **Senior Product Manager Adam Solaiman** and **User Experience Manager Tyson Smith** for a behind-the-scenes look at what it takes to turn complex ideas into scalable products inside large organizations. In this session, they’ll share how teams move from ambiguity to execution—navigating organizational complexity, aligning stakeholders, and continuously evolving products after launch. You’ll walk away with insights on how to: * Build and sustain momentum across teams * Adapt to changing priorities without losing direction * Scale products thoughtfully in complex environments Whether you're driving a new initiative or growing an existing product, this conversation will give you practical strategies to keep things moving forward.
