Virtualization

In the last DevBP meetup before the summer break, we will venture to the world of **Continuous Delivery**, exploring the craft of shipping software safely and continuously — from the practices that keep your releases boring, to the hard-won lessons of building the infrastructure behind a feature toggle. \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- **Continuous Delivery Never Died. It Became a Harness.** with [András Fincza (Draven) - XUND](https://www.linkedin.com/in/andrasfincza/) The PR-centered pipeline was already buckling under big batches, delayed feedback, and overloaded reviewers. Agents just turned up the volume. But the discipline that made CD work in 2015: trunk-based development, fast feedback, sociable testing, feature flags, quality gates. These matter more in 2026, not less. This talk is about what to keep from the old playbook, what to upgrade, and what to stop pretending works. **Building a Feature Flag service** with [Zoltán Dávid - ConfigCat](https://www.linkedin.com/in/zoltan-david/) Everyone knows what a feature flag is. Far fewer know what it takes to build and run a feature flag service at scale. In this talk, we'll go behind the scenes of ConfigCat: the technical decisions, the scaling surprises, and the business lessons that came from serving billions of feature flag evaluations. No introductions to feature flagging, just honest insights from years of building a product in a space where reliability isn't optional. \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- This English-language event will be held at the **Shapr3D office**, where we'll provide snacks and drinks to fuel conversations. Arrival is from 17:30, the presentations start at 18:00. You can also find the recordings of previous events on the [@DevBPMeetup YouTube channel](https://www.youtube.com/@DevBPMeetup).

Az AI most már nem csak külső chatbotként jelenik meg a fejlesztésben, hanem az Oracle APEX világába is egyre mélyebben beépül. Ezen a meetupon gyakorlati példákon keresztül nézzük meg, mit jelent ez APEX fejlesztőknek, PL/SQL fejlesztőknek és vállalati alkalmazásokat építő csapatoknak. Az új verzió fókuszában az **AI-támogatott fejlesztés**, az automatizálhatóság és a modern fejlesztői élmény áll. A 26.1 legfontosabb újdonságai közé tartozik az **APEXlang**, amely olvashatóbb, fejlesztők és AI-eszközök számára is könnyebben értelmezhető alkalmazásleírást ad. Megjelent az **AI Interactive Reports**, amely természetes nyelvi támogatást hoz a riportolásba. Szintén fontos újdonság az **AI Agent Tools**, amely biztonságosabb és kontrolláltabb AI-alapú megoldások építését teszi lehetővé. Beszélünk a **Codex** APEX fejlesztésben való használatáról, az **OpenAI** integrációs lehetőségekről, valamint bemutatjuk azt is, hogyan építhető **projekt szintű chatbot** saját adatok és dokumentumok alapján. Célunk az Oracle Application Express népszerűsítése, a fejlesztői közösség erősítése és olyan gyakorlati megoldások bemutatása, amelyek valódi ügyféligényekre adhatnak választ. Ha érdekel az APEX, a low-code fejlesztés és az AI gyakorlati alkalmazása, regisztrálj minél előbb, mert a helyek csak korlátozottan állnak rendelkezésre. A rendezvény ingyenes, de regisztrációhoz kötött.

**English below ----------------------** Ez most az első picit kötetlenebb könyves eseményünk lesz. Nem egy konkrét könyvet fogunk kibeszélni, hanem inkább kinézünk az Ünnepi Könyvhétre, és meglátjuk, hogyan működik ez a lazább forma. De aggodalomra semmi ok, a könyves kibeszélő és a duma mindenképpen az esemény része lesz. :) A menetrend a következő: **14:00 – Gyülekező és bemutatkozás** A Vörösmarty-szobor környékén találkozunk. Egy nagyobb társaságot keress, és hogy biztosra menj: a kezemben egy Moby Dick könyv lesz, szóval ha ezt látod valakinél, mi vagyunk azok. Kezdésként tartunk egy gyors bemutatkozást, és átbeszéljük, ki mit szeretne megnézni. Én személy szerint csak körbe akarok nézni és megállni ott, ami épp megtetszik, de ha neked komolyabb terveid vagy konkrét célpontjaid vannak, nyugodtan jelezd, biztosan találsz majd valakit, aki veled tart. **14:15 – Indulás a standok közé** 14:15-kor elindulunk, szóval kérlek írj az eseményhez, ha késel. Ha nem érsz oda kezdésre, az sem gond, később is simán be tudsz csatlakozni, rugalmas az egész. A megbeszélt irányok mentén kicsit szétválunk kisebb csoportokra, és teszünk egy kört a forgatagban. **15:00 – Találkozó a Kiskirálylánynál(Vigadó tér)** A nézelődés után 15:00-kor a Kiskirálylány-szobornál találkozunk újra a Vigadó téren. Várunk egy picit, hogy mindenki odaérjen, majd együtt átgyalogolunk a Városháza Parkba (ez egy laza 10 perces séta lesz). **15:20 - 17:00 – Könyves duma a Városháza Parkban** Letelepedünk a parkban, ahol picit átbeszéljük a könyvheti élményeket, meg persze jöhet a kötetlen beszélgetés bármilyen könyvről. A hivatalos részét 17:00-kor zárjuk, de utána is ott lehet maradni tovább, ameddig van kedvünk sztorizni. Gyertek, nézzünk szét, aztán dumáljunk egy jót a parkban! **English version / International attendees:** This is our first casual, free-form event. Instead of discussing a specific book, we’ll visit the Festive Book Week together and see how this format works. * **14:00 – Meetup:** Near the Vörösmarty statue. Look for a bigger group and a guy holding a **Moby Dick** book. We'll do a quick intro and share what everyone wants to check out. * **14:15 – Heading out:** We'll explore the stands in smaller groups. If you're late, just drop a comment here and catch up with us later. * **15:00 – Re-grouping:** At the Little Princess Statue (Kiskirálylány) at Vigadó Square, followed by a 10-minute walk to Városháza Park. * **15:20 - 17:00 – Book Chat:** We'll settle down in Városháza Park to talk about our Book Week finds and books in general. The official event ends at 17:00, but feel free to stay longer! > 🌍 **Language note:** Since this is a local event, most attendees will likely speak Hungarian, but the organizers and many of us speak fluent English. Feel free to join us, we are happy to chat in English and make sure you're included!

[Please register via this link if you’d like to join!✨](https://www.sanctuary.hu/service-page/thursday-morning-flow-08-15-en?referral=service_list_widget) This morning Flow class is a light, continuous practice designed to gently awaken and energize the body for the day ahead. We don’t stay in one pose for too long — movement is guided by the breath, creating a steady rhythm and a sense of flow throughout the class. The pace is soft and seamless, helping the mind settle while gradually building warmth, strength, and mobility. The practice supports releasing stiffness, increasing circulation, and creating space for clarity, focus, and a grounded start to the morning. We close the class with soothing stretches after the dynamic sequence, allowing both the body and nervous system to soften and reset before moving into the rest of the day. Each class follows a weekly changing theme, offering a fresh focus and a new experience every time you step onto the mat.

In this session, we dive into Pranayama, (an ancient practice to discover the flow of energy within) and the power of conscious breathing, which is one of the most important aspects of the original yogic lifestyle. On these Tuesday evenings, we do more than just a breathwork session: this is an opportunity to explore a true harmony between our breath & the mind - body connection. We begin with a 15-minute chest-opening yoga sequence to gently expand our lungs and prepare for deeper breathing (no need for gym clothes though, just an open mind). Then, we explore different breathing techniques designed for self-awareness, relaxation, and energy flow. These classes are designed to help you discover how breath can be a tool to balance, energize, and center yourself. To close, we immerse in a short yet profound "silent concert", a meditative sound journey where 174 Hz sound waves or white noise guide us into a state of deep harmony. Whether emotions are light or heavy, thoughts are clear or clouded, this is a space to simply be and find some peace.

Join the next Budapest Quant Group meetup for an exciting presentation by **Gábor Vigh, Director at MQA, Citi**, on cutting-edge machine learning methods in quantitative finance. The event concludes with networking. **Abstract:** Accurate and efficient calibration of equity volatility surfaces is fundamental to equity derivative pricing. When markets quote only American option prices, this task becomes significantly more complex. We present a neural network-based approach that overcomes these challenges, delivering calibration results while reducing the computational burden of conventional approaches. **Mandatory registration:** please send a mail to the following address: kinga.doktor@citi.com, with the following details: * name * company * job title **Agenda** * 18:30-19:00 Reception.

We are recruiting new group leaders for virtual men's groups! Our primary groups are outdoor movement groups, but we are launching virtual groups for the state of Ohio and beyond and the groups will move outside in the spring, creating room for men's groups, women's groups and coed groups all over the country. Read below to learn about our groups and click the links at the bottom to apply. ### **What is an Outdoor Empowerment Group?** Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being. Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment. ## **Why Join?** * **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance. * **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space. * **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection. ## **The Ideal Group Leader** The ideal group leader * Has a born-in passion for mental health, movement, connecting with nature and building community. * Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us. * Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind. * An ability to manage groups with high emotional intelligence and desire for human connection. * An ability to self-motivate and market/promote their group on Facebook and other social platforms. * Nature informed therapy or clinical therapists/psychologists a plus. ## **Our Impact**  Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported: * A noticeable improvement in mental clarity and emotional well-being. * An increase in social connection and a sense of belonging. * Said they would return again. We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself. ### **Why Our Groups are Donation-Based** Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission! Every contribution helps us: * **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization. * **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year. By choosing to contribute, you’re not just leading an event—you’re helping build a mental health movement that supports long-term well-being and connection for all during a severe mental health epidemic. ## **Come Join Us!** We’d love to have you be part of this growing community of people prioritizing their mental health, movement, and connection. 🔹 **Visit Our Website to Learn More:** https://speakyourmind.men/joinusoutside 🔹 **Apply Here to Lead Your Own Group!** – https://form.jotform.com/taketimespeakyourmind/sym-group-leader-application 🔹 **Support the mission**: If you resonate with the mission and want to support, feel free to join a group before applying or donate to help us reach our goals to help more people!

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/).

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.

Couldn't make Knowledge? Or want to debrief the dancing robots or Autonomous Workforce? Join us for a Knowledge '26 recap, insights sharing, a couple rounds of golf, and fun at Topgolf. As always, drinks and food will be provided. More details to come — mark your calendar, RSVP, and save your spot today!
