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. A tervezett program: 17:30 - 18:00 - Gyülekezés, regisztráció 18:00 - 18:10 Köszöntés, bevezetés, beszámoló az APEX World-ről (Pataki Dávid) 18:10 - 19:00 Az APEX 26.1 és az AI támogatott fejlesztés (Pataki Dávid) 19:00 - 19:10 Zárás, Kahoot (Pataki Dávid)

**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!

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. The attendees need to enter the Promenade Gardens Building, the presentation will take place on the fifth floor in the Citi office (ask for help at the reception) * 19:00-20:30 Presentation and Q&A * 20:30 Networking **Address:** 5th floor, Promenade Gardens (Citi building) 80, Váci str. Budapest, 1134.

Practice Buddhist meditation in the middle of Budapest! The meditation is suitable for beginners. Each regular meditation is guided and begins with a short introduction. (all together is about 30-40 minutes) Our regular Buddhist meditations have proven popular with people who want to integrate authentic Buddhist methods into their daily lives. For the modern lay person who is juggling work, relationships, and an active role in society, we teach a meditation that is easy to learn, and profound and powerful for experienced practitioners. The meditation originates from the Karma Kagyu tradition of Tibetan Buddhism. It has a cumulative effect on mind, leading to greater clarity and calmness. Fearlessness, joy, and active compassion are the result of regular practice of Buddhist meditation. * Do I need any special clothing? No special clothing needed. * Does the attendance cost anything? No, the meditation is free.

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
