Large Scale Scrum

💜 Csak nőknek szóló PyLadies esemény! 💜 Gondoltál már arra, hogy miért kellene újra és újra leírnod ugyanazt a kódot, ha egy feladatot többször is el akarsz végezni? A Python függvények pont ebban segítenek: egyszer megírod a kódot, elnevezed, és utána annyiszor használod, ahányszor csak szeretnéd. Ezen az előadáson közérthető nyelven, lépésről lépésre fedezzük fel a függvények alapjait, kezdőknek és újrakezdőknek is ideális módon: • Mi az a függvény? Egy „miniprogram”, ami egy meghatározott feladatot végez el – megnézzük, miért ez a Python egyik legfontosabb építőköve. • Hogyan hozhatsz létre egyet? A def kulcsszó használata, beszédes függvénynevek, és az első saját függvények megírása. • Paraméterek csínja-bínja: Megismerjük a pozíciós és kulcsszavas argumentumokat, az iterálható objektumok csomagolását (unpacking), valamint azt is, hogyan használhatjuk okosan a \*args és \*\*kwargs lehetőségeit. Szó lesz az alapértelmezett paraméterekről és arról is, mire érdemes figyelni velük kapcsolatban. • Változók láthatósága: Amikor a Python egy változó értékét keresi, először a lokális névtérben vizsgálódik. Ha ott nem találja, továbbmegy a befoglaló függvény névterébe, majd a globális névtérbe, végül pedig a beépített névtérbe. Ezt a folyamatot a függvények működésén keresztül is részletesen áttekintjük, sok gyakorlati példával. • Egy kis „szuperképesség” a végére: Rövid betekintést adunk a dekorátorok világába is. Bár haladóbb téma, megmutatjuk, hogyan tehetik még okosabbá és testreszabhatóbbá a függvényeinket anélkül, hogy bonyolítanánk a kódot. Ha szeretnéd jobban megérteni, hogyan szervezd tisztábban és hatékonyabban a Python kódodat, ez az alkalom neked szól. Várunk minden érdeklődőt – akár most ismerkedsz a Pythonnal, akár már használod, de szeretnéd mélyebben megérteni a működését. 🐍✨ 👨‍💻 Előadó: Péter Fülöp 🗓️ Programterv • 17:30 – 18:00 Megérkezés, setup • 18:00 – 19:00 Előadás I. • 19:00 – 19:20 Szendvicsek & frissítők • 19:20 – 20:10 Előadás II. • 20:10 – 21:00 Networking (A programterv változásának jogát fenntartjuk.) 💻 Mivel készülj? Workshop jellegű alkalom lesz, így hasznos, ha hozol magaddal egy programozásra alkalmas számítógépet. Jó, ha előre megismerkedsz egy Python Notebookkal, például a Google Colab-bal (ehhez egy Google-fiók szükséges). Ha kell bármi segítség, gyere kicsit hamarabb és segítünk! 💜 Kit várunk? Olyan **lányokat/nőket**, akik most ismerkednek a Python nyelvvel, vagy szeretnék meglévő tudásukat bővíteni vagy felfrissíteni. 📍 Helyszín Balance Irodaház – 7. emelet Dél (Lifttől balra) Cím: 1139 Budapest, Váci út 99 ‼️ Következő alkalmunk nem a megszokott helyszínen lesz, hanem a főépületben, és kisebb térben, így a létszám limitált.

Google Research published a paper at NeurIPS '25 : ["Nested Learning: The Illusion of Deep Learning Architectures"](https://abehrouz.github.io/files/NL.pdf) It is a new approach to look at machine learning problems: architecture & optimization algorithms together In NL, training models is not treated as one opaque, atomic process. But as **a** **system of interconnected, multi-level learning problems** that are **optimized in parallel**. The goal is to solve one of the core challenges of modern LLMs: **continual learning** (the ability for a model to acquire new skills over time without forgetting old ones.) Authors argue: the model's **architecture and the optimization algorithm are fundamentally the same concepts;** they are just different "levels" of optimization, each with its own internal flow of information and update rate We'll walk through: \- how the paper unifies model architecture and optimizers \- architectural decomposition of a classical learning problem solved in the framework of Nested Learning \- how optimizer algorithms fit into the NL framework \(backrpop as associative memory\) \- the concept of continuum\, multi\-timescale memory \- Hope \- an architectural backbone of NL === ENTRY DETAILS === \- QR code with entry information is available\, in the "Photos" section of this event page\. \- Gate closes at 18:15 \- no late entries\.

#### **Upcoming Book Club Meetings at Közkincs Könyvtár** We will be starting the new year with two exciting reads — one from a Hungarian literary giant and Nobel Prize winner and one from a contemporary American novelist. Whether you’ve been with us from the beginning or are joining for the first time, you’re warmly invited to dive into these richly layered, discussion-worthy books with us. As always, everyone is welcome, whether you’ve finished the book, are halfway through, or simply want to listen and participate. ##### **January Book Club Meeting** **Book:** *The Melancholy of Resistance* — László Krasznahorkai **Date:** January 28 **Time:** 7:00 PM **Location:** Közkincs Könyvtár We’ll open the year with Krasznahorkai’s haunting and visionary novel — a dense, hypnotic, and darkly comic exploration of chaos, authority, and the strange currents that move through small communities. One of Hungary’s most acclaimed literary works, and the basis for Béla Tarr’s film *Werckmeister Harmonies*, it offers plenty to discuss in terms of style, structure, philosophy, and atmosphere. ##### **February Book Club Meeting** **Book:** *The Nix* — Nathan Hill **Date:** February 25 **Time:** 7:00 PM **Location:** Közkincs Könyvtár In February, we’ll switch gears with *The Nix*, a sprawling, funny, sharp, and surprisingly emotional novel about politics, media, family history, and the stories we tell about ourselves. It moves between time periods and perspectives with enormous energy — giving us a contrast to January’s slow-building, immersive style.

El objetivo de este encuentro es romper el hielo, hablar de las historias que nos gusta escribir, de por qué escribimos, de los libros que nos gusta leer, de qué dificultades encontramos al enfrentarnos al folio en blanco y de qué esperamos del grupo. En definitiva, se trata de conocernos como personas para entendernos como escritores. No importa si has escrito diez novelas, cuatro cuentos o el precioso título de un poema sin versos. Aquí todo aspirante a juntaletras es bienvenido.

The February edition of Green Meetup is here, and the topic is local communities! If you are: * working or interested in sustainability, * interested in bringing climate action into your current role, * or just looking to grow your network, exchange ideas, and connect with like-minded people, …this event is for you! Whether you are new to Budapest, a local or just visiting, we encourage you to join us on the 27th February at 18:00 in the city center for a friendly event to mingle with like-minded people. Our events are in English, so don't worry if you don't speak Hungarian. **Let's meet at KUBIK Coworking office!** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **What to expect:** 1. 17:45 - 18:00: Attendees arrive. 2. 18:00 - 18:10: **Greetings and introduction** 3. 18:10 - 19:00: **[Luca Michaletzky](https://www.linkedin.com/in/luca-michaletzky-866327aa/) \- Local communities as engines of systemic change** How can city neighborhoods drive deep systemic change, and how can local communities build social resilience that weaves a stronger safety net for everyone? In this workshop, we’ll introduce Joanna Macy’s idea of The Great Turning and explore why sustainability alone isn’t enough. Through discussion and small-group brainstorming, we’ll cover how to find your passion or mission and turn it into community action. What practical projects can urban dwellers start? More importantly, why should they do it, and how can they facilitate the change? By the end, you’ll walk away with inspiring questions and concrete ideas for action in your own community. 4. 19:00 - 20:00: **Mingling** Have thought-provoking conversations and exchange ideas with other community members on the topic of sustainability. Drinks and snacks included! This event's speaker is Luca Michaletzky, ecopsychologist: *Luca Michaletzky is a psychologist working from an ecopsychological perspective. She is also an organizer of the Világeleje community — a movement inspired by András Takács-Sánta’s book Világeleje (The beginning of the world) — and contributes to the websites [vilageleje.hu](https://vilageleje.hu/) (guiding people along the path of active hope) and [kiutak.hu](https://kiutak.hu/) (offering over 100 ecological action tips for small communities).* \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Let's share, learn, and build something meaningful together! **Note**: The talks will be recorded and published on YouTube.

The Men’s Circle of Excellence Gathering, for men who seek truth, mastery, and a life beyond mediocrity. The goal is simple: to support each other in mastering mind and spirit, breaking free from comfort, and moving toward excellence in every area of life. Modern life offers endless distractions but little real connection. Too often, men walk the path of self-development alone, or struggle against the negative pull of today’s society. The Men’s Circle of Excellence was created to change that: to bring support, accountability, challenge, and community energy. We gather in person to share openly, confront fears, and inspire one another to reach higher. Here, power is rooted in virtue, strength is balanced with empathy, and ambition is guided by wisdom. How it works: • Welcome & introductions: Meet new members and reconnect with familiar faces. • Open sharing: Each man speaks about his current challenges, fears, or obstacles. • Honest reflections: The group responds with insight and encouragement. • Connection Time: After the circle, we'll have extra time to relax, talk, and build friendships. Recommendation: • Before the event, take some time to think about your current situation and what to bring into the circle. Limited to max. 8 men per gathering to keep the space focused, personal, and meaningful. Confirm your attendance to reserve your spot.

**IMPORTANT: If you haven't already, please make an account on [budapestracketclub.com](https://budapestracketclub.com/), soon it will be our main platform for scheduling events.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
