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 Upcoming Thursday Sessions for Spring and Summer Season: 7.5.2026 at 18:30–20:00 (CET) 14.5.2026 at 18:30–20:00 (CET) 4.6.2026 at 18:30–20:00 (CET) 11.6.2026 at 18:30–20:00 (CET) 18.6.2026 at 18:30–20:00 (CET) 25.6.2026 at 18:30–20:00 (CET) 2.7.2026 at 18:30–20:00 (CET) 9.7.2026 at 18:30–20:00 (CET) 23.7.2026 at 18:30–20:00 (CET) 30.7.2026 at 18:30–20:00 (CET) Zoom link for all sessions: https://us02web.zoom.us/j/89766267672 Open Heart ashram (meditation center) is located in Zgornje Gorje, Slovenia.

Rainbow Body Yoga – Level 1 Online Course We warmly invite you to join the Rainbow Body Yoga Level 1 Course, a transformative practice from the Open Heart tradition. The course is taught by Amrita Rani, an ordained sangha member and trained Open Heart instructor. You are welcome to join either in person in Zgornje Gorje, Slovenia, or online via Zoom. Rainbow Body Yoga is a profound tantric non-meditation practice designed to deconstruct the selfing mechanism of the mind. Through the Guru mantras of Padmasambhava and Yeshe Tsogyal, subtle energy practices, and dynamic concentration, we cut through self-based energies that block the direct recognition of our natural state. Although regarded within the tradition as a post-awakening purification practice, you do not need to be awakened to begin. The practice itself deepens recognition of the selfless state, supporting further awakenings and the maturation of clarity. Both those who have experienced awakening shifts and those who feel called to deepen their spiritual path are warmly welcome. This carefully structured sequence works directly with the causal body, where self-based energies are stored. We examine the klesha of ignorance (avidya), the root of existential suffering. With the Guru’s blessings, RBY techniques, and vipashyana (direct seeing), even the subtlest layers of selfing can be cut through. As the practice deepens, you become familiar with the clarity and aliveness of your enlightened mind. Eventually, you recognize that wakeful awareness has always been present, even within negative thoughts and emotions. As mental clutter dissolves into the natural state, increased clarity brings deep healing. Self-sabotaging patterns can be liberated, and the energy once consumed by worry and rumination becomes available to you. Practiced consistently, Rainbow Body Yoga reveals the natural luminosity of selfless awareness and leads toward the realization of emptiness, not as a concept, but as a living experience. These precious practices were given to Amrita Baba by Padmasambhava through visionary transmission, offering a direct path beyond self-based suffering. Level 1 provides a grounded and systematic introduction, enabling you to continue confidently with your home practice. The process is powerful, deeply rewarding, and often brings tangible results relatively quickly. You’re welcome to join either of the weekend courses, or both, if you wish. However, attending just one weekend is already enough to begin practicing on your own. First Weekend Course 📅 20–21 June 2026 🕒 3:00–9:00 pm (CET) Dinner break approximately 6:00–7:30 pm each day Participation fee: Sliding scale €100–200, depending on your financial situation. Please make your payment in advance via PayPal to: kaisaeskeli@gmail.com Register by emailing Amrita Rani at kaisaeskeli@gmail.com. You will receive the Zoom link for all sessions. If you are joining in person, you will receive the address of the event location in Zgornje Gorje, Slovenia. Welcome all!

Hallo liebe Java User Group Mitglieder! Diesmal haben wir zwei Bonner Kollegen zu Gast: * Martin Stoller: **Backend-Performance in Hochlast-Systemen: Lösungsansätze aus dem Data Engineering** * Andreas Monschau: **Zehn goldene Regeln, um dein Softwareprojekt zuverlässig zu ruinieren** Wir freuen uns euch zu sehen (virtuell oder vor Ort). Dank an [codecentric](https://www.codecentric.de/standorte/nuernberg) für Location, Bier und Pizza! ================= Viele Hochlast-Systeme beginnen als kleine, unscheinbare Prototypen - gebaut mit bewährten Mitteln wie relationalen Datenbanken, objektorientierter Business-Logik und klassischen Request-Response-Architekturen. Doch was passiert, wenn diese Systeme plötzlich nicht mehr Tausende, sondern Millionen von Requests bedienen oder Terabytes an Daten verarbeiten müssen? In der Praxis zeigt sich häufig: Klassische Optimierungen wie Caching, horizontale Skalierung oder effizientere Algorithmen stoßen irgendwann an ihre Grenzen, weil sie innerhalb desselben Paradigmas bleiben. Dieser Vortrag zeigt, warum echte Skalierbarkeit oft ein Umdenken erfordert. Anhand eines durchgehenden Praxisbeispiels wird schrittweise demonstriert, wie sich ein System von einer latenzoptimierten Request-Response-Architektur hin zu einem durchsatzoptimierten, analytischen System entwickelt. Dabei werden zentrale Konzepte aus dem Data Engineering greifbar gemacht - darunter Precomputation, Batch Processing, deklarative Verarbeitung und Denormalisierung - und in den Kontext klassischer Backend-Entwicklung eingeordnet. Die Teilnehmenden lernen, typische Grenzen traditioneller Architekturen zu erkennen und erhalten ein alternatives Denkmodell, um High-Throughput-Systeme gezielt und nachhaltig zu skalieren. ================= Softwareprojekte sind chaotisch, anstrengend und voller Überraschungen. Und ganz ehrlich: So soll es auch bleiben. Ordnung würde ja nur den Spaß verderben. Trotzdem gibt es immer wieder Menschen, die glauben, man könnte Projekte wirklich zu Erfolg führen… unglaublich, oder? Damit dir so etwas nicht passiert, zeige ich dir in diesem Vortrag, wie du ein Softwareprojekt in 10 einfachen Schritten zuverlässig an die Wand fährst. Die „goldenen Anti-Pattern für maximalen Projektschaden“ entstammen jedoch nicht meiner Fantasie, nein, sie werden in der Realität täglich mit beeindruckender Konsequenz praktiziert. Und das Beste: Sie wirken nachhaltig. Manche dieser Muster entfalten ihre volle Zerstörungskraft erst Monate später. Nachdem du alle Regeln kennengelernt hast, kannst du selbst entscheiden: Möchtest du sie weiterhin anwenden, oder vielleicht doch etwas verändern? Solltest du allerdings inspiriert sein, eines dieser Anti-Pattern künftig noch konsequenter zu leben… dann sollten wir uns nach dem Talk dringend unterhalten. ================= Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. Please RSVP via [Microsoft Build //localhost:columbus | Microsoft Reactor](https://developer.microsoft.com/en-us/reactor/events/27247/).

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink.

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle. **Optional topic for this meetup: Where is everybody?** In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox. One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread. Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for. **Questions to wrestle with:** * Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving? * Where do you bet the filter sits, behind us or ahead of us, and why? * If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming? * Does any of this change how you live, or how humanity should be spending its time and money right now? As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 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. **YouTube Link** TBD
