Open Heart Meditation with Amrita Rani
Open Heart Meditation Sessions with Amrita Rani
(Live in-person and online on selected Thursdays via Zoom)
You are warmly invited to join the Open Heart Meditation Sessions with Acharya Amrita Rani — a living space of awakenings and direct experience.
These sessions are created both for beginners and seasoned practitioners who wish to deepen their meditation practice, stabilize awakening, and walk the path of enlightenment with guidance and support. Whether you are new or experienced, each gathering offers a grounded structure to help you build consistency in daily practice and grow in confidence on your spiritual path.
At the heart of Open Heart teachings is direct recognition. Through the Two-Part Formula and precise meditative guidance, you are supported in shifting from self-based mode into selfless awareness, again and again, until cessation of suffering takes place.
A central and deeply transformative practice in Open Heart is guru yoga. Through guru yoga, the practitioner directly connects with awakened awareness through devotion, transmission, and experiential recognition. With the help of this profound method, one recognizes their true selfless ease, the natural, effortless state beyond space and time.
Alongside guru yoga, the sessions include insight meditation (Vipashyana), tantric methods, dynamic concentration, trauma-healing techniques, and foundational practices such as Bodhicitta prayers. Each session includes guided meditation, space for questions, reflection, and personal support.
Rani’s meditation sessions are held live on Zoom on selected Thursdays from 18:30 to 20:00 (CET). Recordings may be available for continued integration and practice on her YouTube channel, The Sweetness of Enlightenment.
Participation fee:
15 € per session
Please make your payment in advance via PayPal before joining, to Rani’s PayPal account: kaisaeskeli@gmail.com

RO:SEC - KI-Agenten & Code im Security-Check: Zwischen Hype, Hack und SAIF 2.0
Am 24.06.26 steigt unser nächstes Codineers Rosenheim Meetup vor Ort in unserem Büro in Rosenheim oder Remote via Zoom.
Meeting Link: [https://qaware-de.zoom.us/j/88063201327?pwd=1CYwSe7eGIBM3FJWygby1oixvzXUwg.1](https://qaware-de.zoom.us/j/88063201327?pwd=1CYwSe7eGIBM3FJWygby1oixvzXUwg.1)
Meeting-ID: 880 6320 1327
Kenncode: tW8JTFtiSF
**\#\# KI\-Agenten & Code im Security\-Check: Zwischen Hype\, Hack und SAIF 2\.0**
Vom nützlichen Entwickler-Tool bis zum autonomen System: KI-Agenten übernehmen immer mehr Kontrolle. Sie generieren Pull Requests, führen eigenständig Code aus und handeln im Namen der User, oft komplett ohne menschliche Aufsicht.
Doch wo endet der Hype und wo beginnen die echten Risiken? Was taugen die integrierten Sicherheitsfeatures aktueller Modelle, wenn sie auf die Realität der Softwareentwicklung treffen? Und wie groß ist der "Blastradius", wenn Agenten durch präparierte E-Mails manipuliert werden?
Dieses Meetup liefert dir einen fundierten Security-Deep-Dive. Wir analysieren reale Vorfälle, prüfen die aktuellsten Anthropic-Modelle auf Herz und Nieren und stellen dir konkrete Design-Prinzipien (SAIF 2.0) vor, mit denen du deine KI-Systeme absicherst bevor sie live gehen.
**\*\*\* Agenda \*\*\***

**\*\*\* Unsere Vorträge \*\*\***
**Zwischen Hype und Realität: Anthropic-Modelle und "Project Glasswing" im Security-Check**
In diesem Vortrag werfen wir einen kritischen Blick auf die aktuelle Leistungsfähigkeit der neuesten Anthropic-Modelle und schauen unter die Haube von Entwicklertools wie der Claude CLI.
Im Zentrum steht dabei die Perspektive der IT-Security: wie sicher ist AI-Code? Was bringen die mitgelieferten "Sicherheitsfeatures"?
Zudem wollen wir natürlich auch wissen, ob Mythos uns zeitnah unseren Job wegnimmt: Deswegen ziehen wir ein Fazit nach zwei Monaten Project Glasswing. Was ist Fakt, was Fiktion?
**SAIF 2.0 – Sicherheitsstrategien für die Ära autonomer KI-Agenten**
KI-Agenten sind längst im Produktiveinsatz: Sie generieren Millionen von Pull Requests, lösen Support-Tickets und verwalten die interne Unternehmenskommunikation.
Sie sind keine bloßen Chatbots. Sie verfügen über Zugriffsrechte, führen eigenständig Code aus und handeln im Namen der User – komplett ohne menschliche Aufsicht.
Doch diese Autonomie vergrößert den potenziellen Blastradius enorm.
Die Beispiele aus der Praxis sprechen für sich: Eine einzige präparierte E-Mail verwandelte Microsoft 365 Copilot in ein Werkzeug zum Datendiebstahl. Ein simpler einzeiliger Prompt brachte den Chatbot eines Autohauses dazu, einem 1-Dollar-Verkauf zuzustimmen – vor den Augen von Millionen. Das sind keine kuriosen Einzelfälle, sondern das Resultat von Produkten, die ohne das nötige Sicherheitsfundament entwickelt wurden.
Googles Secure AI Framework 2.0 (SAIF) ist die Antwort aus der Praxis. Es identifiziert 15 spezifische Risiken, ordnet sie den Komponenten eines KI-Systems zu und liefert konkrete Sicherheitsmaßnahmen. SAIF 2.0 erweitert diesen Rahmen gezielt für agentische Systeme: Es zeigt auf, wo sie versagen, warum die Risiken hier höher liegen und wie wir die Architektur grundlegend neu denken müssen.
Dieser Vortrag analysiert die SAIF-Architektur anhand realer Vorfälle und schließt mit fünf entscheidenden Design-Prinzipien ab, die den Blastradius Ihrer Agenten minimieren, bevor sie live gehen.
Wir sind Partner der [ROSIK](https://www.rosik.com/).
From Real-Time Intelligence to Legacy Mastery: The Era of AI Agents
**Cloud Native Night Munich**
AI agents are rapidly evolving from simple assistants into autonomous systems capable of reasoning, maintaining context, and interacting with complex environments. In this meetup, we’ll explore two practical applications of modern agentic AI in software engineering.
The first talk dives into building stateful AI agents that work with real-time data, covering the architectural patterns and challenges behind creating responsive, context-aware systems. The second talk showcases how agentic AI can be applied to understanding and analysing complex legacy applications — helping uncover program flows, dependencies, and hidden system knowledge that would otherwise take countless hours to explore manually.
Whether you’re building AI-powered applications, modernising enterprise systems, or simply curious about the future of intelligent software, this meetup offers hands-on insights into how AI agents are transforming the way we interact with technology
THIS MEETUP WILL BE HYBRID. **\|** Zoom Link will be available shortly before the meetup
\*\*\* AGENDA \*\*\*
* 6\.30 PM \| Doors open\. Grab some snacks & drinks\.
* 7\.00 PM \| Welcome & Intro – **Start of hybrid meetup**
* 7\.15 PM \| **Building Stateful AI Agents with Real-Time Data**, Gregor Bauer (VP Customer Engineering at CrateDB)
* \~8:15 PM \| **Hosty - The next level with Agentic AI,** Martin Binder (Lead IT Consultant at QAware)
* afterwards: More snacks & drinks, and a lot of time for networking with all attendees and speakers.

**Building Stateful AI Agents with Real-Time Data**, Gregor Bauer (VP Customer Engineering at CrateDB)
Most AI demos are stateless. Real systems are not.
Modern AI applications increasingly depend on continuously changing operational data: events, metrics, logs, transactions, sensor streams, and user activity. This creates a new architectural challenge: how do we build AI agents that can reason over live data while remaining scalable and observable ?
This talk explores the architecture of stateful AI systems and agentic applications. We will cover:
* streaming-first AI architectures
* real-time context enrichment
* combining vector search with structured queries
* memory layers for AI agents
* latency and scalability considerations
* operational lessons from large-scale data platforms
The session provides practical guidance for engineers designing production-ready AI platforms.
**Hosty - The next level with Agentic AI,** Martin Binder (Lead IT Consultant at QAware)
To migrate legacy systems, you need to understand these IT dinosaurs, at least partially. So code analysis up to a certain level is unavoidable. What used to take months, sometimes years without LLMs is now doable in a few days with Gemini and friends. And yet: you still have to drive the analysis yourself, stitch the LLM's partial results into a coherent picture and fight the context window. With old source files thousands of lines long, that part really hurt.
Agentic AIs like Claude Code are not just another AI feature. They change how you approach unfamiliar systems — fast, and without the headaches that LLM chat workflows used to come with. Teaser: an analysis that took us a few days under "yay!" cheers is now done in minutes.

You will need to scan your ID at the door to get a visitor badge.
**Abstract**
*Customize the IDE: Building Extensions for Visual Studio Code*
Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs.
In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling.
The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options.
