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.

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 will beavailable soon\, in the "Photos" section of this event page\. \- Gate closes at 18:15 \- no late entries\.

The February edition of Green Meetup is here, and the topic is local communities!

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.

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
