**Pop-Up MTG Commander Game! (Casual Play & MagicCon Prep)** Hey everyone! Whether you’re a seasoned planeswalker or completely new to the game, join us for some casual, multiplayer **Magic: The Gathering Commander**. I’m fairly new to the game but practicing in earnest ahead of **MagicCon Amsterdam**, and I'd love to connect with the local community for some fun, relaxed games. Since it's my first time trying to play the game at a bar, let's see how the cards sling alongside some drinks! 😅 * **Who:** Anyone! New and experienced players are all welcome. * **Decks:** Bring your own, or borrow one of my extra precons if you don't have cards. Untap, upkeep, and draw your opening hand—let's hit the battlefield! Shuffle up and drop a comment if you're ready to join the pod. ⚔️ ✦•······················•✦•······················•✦ Kat is a writer and teacher, formerly based in New York City.

*Nem a framework a nehéz, hanem az emberek* Egy transzformáció megvisel minden szervezetben dolgozót -pozíciótól függetlenül-. A csapattagok felé számtalan új elvárást kommunikálnak, a felsővezetők hirtelen elkezdenek magasabb szinten tervezni. De mi van a középvezetőkkel? Gyakorlatilag ők lesznek a "transzformációs belső tolmácsok" egyikei. Elvárásokat támasztanak feléjük. De vajon a segítséget is megkapják ezekhez? Célunk, hogy gyakorlati szituációkon keresztül bemutassuk, hogy mi milyen kihívásokkal találkoztunk, és milyen megoldásokkal próbálkoztunk. Pláne, amik működnek... :) [Horányi Emese](https://www.linkedin.com/in/emese-horanyi/), az Uniqa agilis coach-a, perspektívikus coach alkalmazotti szemmel, míg [Spánn Richárd](https://www.linkedin.com/in/rich%C3%A1rd-sp%C3%A1nn-3a56317b/), transzformációs tanácsadóként, külsős szemmel világít rá a lehetőségekre. \-\-\-\- Please note that this event is for Hungarian speakers only.

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.

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).

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.

Ez az izgalmas játék az élőszereplős változata az asztali vagy online szerepjátékoknak, vagyis a résztvevők szerepeket öltenek magukra – hogy milyet, az a játék témájától függ, pl. vadnyugati, jövőbeli, ókori. Komoly jelmezekre nincs szükség, de nincsenek kizárva sem. Mivel még nincsen közösség, ezért a mostani alkalom egyszerűen csak találkozással, ötleteléssel fog telni, a cél pedig egy közösség létrehozása. Már 3-4 fő is elég az elinduláshoz. Kor limit nincs, hiszen elvileg mindenki találhat magához illő szerepet. Helyszín és időpont: Kopaszi-gát, Öböl amfiteátrum, Öbölház előtti rész 2026-06-13. (szombat) 10:00-11:00

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.

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/).

**Abstract:** Motivated by the challenges of detecting extremely rare failures in sophisticated circuit design specifications, we study the problem of efficiently identifying multiple disjoint regions of interest (ROIs) — regions of a continuous, high-dimensional parameter space where a complex, expensive-to-evaluate target function falls below or above a pre-specified threshold. We reframe this problem as a Bayesian sequential decision-making problem and, more broadly, as an instance of strategic agent behavior in continuous spaces: an agent that must allocate a hard evaluation budget intelligently, updating its belief about the unknown function after each observation and choosing the next query to maximize coverage of all disjoint failure regions rather than convergence to a single optimum. This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1](https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1) Meeting ID: 893 7923 0295 Passcode: 5t5WYn **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
