It focuses on procedural, non-destructive workflows that enable fast generation of plants ranging from grass and flowers to complex trees, while making it easy to produce and maintain large numbers of variations. A live demonstration guides the audience through the entire process of plant creation, from initial design to integration in Unreal Engine. CZ: Přednáška představí *Botanica*, nezávislý nástroj určený pro tvorbu a správu vegetačních assetů ve virtuálních prostředích. Zaměřuje se na procedurální, nedestruktivní workflow, který umožňuje rychlé generování rostlin od trávy a květin až po složité stromy, a zároveň usnadňuje vytváření i dlouhodobou údržbu velkého množství variací. Živá ukázka provede publikum celým procesem tvorby rostliny, od prvotního návrhu až po integraci do Unreal Engine. 19:40 **ROBLOX: Game engine pro nejhranější UGC hru na světě/Game engine for the world’s most-played UGC platform** *(Michal Benátský - ROBLOX)* CZ: Jak funguje rendering engine, který musí běžet skoro úplně na všem a přitom zobrazuje jeden a ten samý obsah? Od deset let starých Android telefonů až po nejnovější PC. Každý den, na témeř stovkách milionů zařízení. Jeden z leaderu na enginu je i Čech: Michal Benátský, Principal Software Engineer, který byl jedním ze tří zakládajících rendering programátorů v Robloxu a už 11 let pomáhá určovat směr jeho vývoje. Dnes na enginu pracuje tým přibližně 25 lidí a jde o jeden z nejpoužívanějších enginů na světě. Talk se zaměří na to, jak engine skutečně funguje. Jaké kompromisy jsou nutné pro extrémní scalabilitu a výkon. EN: How does a rendering engine work when it has to run on almost everything, yet display the exact same content? From ten-year-old Android phones to the latest PCs. Every day, on nearly hundreds of millions of devices. One of the engine’s leaders is Czech: Michal Benátský, Principal Software Engineer. He was one of Roblox’s three founding rendering programmers and for the past 11 years has helped shape the direction of its development. Today, the engine is developed by a team of roughly 25 people and is among the most widely used engines in the world. This talk will focus on how the engine really works, and on the trade-offs required for extreme scalability and performance.. 20:30 - 21:00 Ukončení akce a přesunutí do blízké restaurace / End of the event and move to a nearby restaurant Originál Formanka https://maps.app.goo.gl/QUE5cnqsJ2vankJk8

**Talks:** **BE-A: AI hotelová recepční: Python, fastapi, langchain, TTS/STT, K8s** *by Lukáš Korous* Na praktickém příkladu ukážeme, jak navrhnout autonomní AI systém, který je spolehlivý a zná své limity. Nemusí umět všechno, ale to, co dělá, musí fungovat bez chyb. Podíváme se, jak se to promítá do architektury, testování i provozu. **Schedule** **18:30** – Doors open **19:00** – Talk “BE-A: AI hotelová recepční” 19:45 – Lightning talks: add yours to [https://bit.ly/prpylight](https://bit.ly/prpylight) after 20:00 – Networking **Good to know** * You don’t have to register for this meetup – the actual attendance is much bigger (40–70 Pythonistas) than indicated in the “Going” list here. * **Cash only payments – club doesn’t accept cards.** * Talks at Pyvo are mostly in Czech but it there’s somebody who doesn’t understand Czech talks are switched to English if the speaker is able to do so. * Besides both soft drinks and beer it's possible to eat at the club.

How are community builders actually using AI in their day-to-day work—beyond the hype and into real workflows? ​Join us for a Community Chatter focused on practical AI tools and approaches that help teams move faster, support their people better, and rethink how communities grow. This session brings together speakers who have built and deployed their own AI-powered solutions—from editorial coaching agents and community automation stacks to internal knowledge assistants employees actually trust. ​You’ll hear how AI is being used to: * ​turn rough ideas into publishable content without bottlenecks * ​better understand and manage growing communities * ​create reliable, accessible knowledge systems inside organizations ​**Speakers & Talks** ​[Jan Meissne](https://www.linkedin.com/in/necasjiri/?utm_source=luma)[r](https://www.linkedin.com/in/jan-meissner/?utm_source=luma) *Coaching, Not Gatekeeping: Building an AI Editorial Agent for Our R&D Blog* The more AI handles the routine, the more the human stuff matters. This talk is a small story inside that bigger one. A year ago, this would have been a favour I'd ask a senior engineer for - and then keep bothering them about every time something broke. Instead, I built it myself: an AI-powered editorial coach that helps our engineers, PMs and designers turn rough ideas into publishable blog posts. Azure Functions, React, Claude. Things I'd nodded along to at conferences for years and never expected to actually touch. I'll share how it was structured, tuned, and what it changed about how people write and publish. Although I hit a token limit in Claude Code halfway through. It's in production anyway. ​[Láďa Vašek](https://www.linkedin.com/in/ladislav-vasek/?locale=en&utm_source=luma) *From Chat to Code: How We Run a 500-Member Community with AI (Without Being a Developer)* A practical, no-code journey through building and running a community with AI tools. Láďa will walk through his stack and share a surprising insight: not all members matter equally—and AI can help you figure out who actually does. ​[Jirka Nečas](https://www.linkedin.com/in/necasjiri/?utm_source=luma) *Good Input Means Good Output: How We Built an AI Agent Employees Actually Trust* A behind-the-scenes look at building an internal AI assistant that employees actually use. Jirka will show how leveraging existing data, analyzing real employee questions, and embracing imperfect systems can lead to a reliable, everyday knowledge tool. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ​This event is organized for the Czech community of community builders, especially those working with engineering and tech teams—but everyone curious about practical AI in community and team enablement is welcome.

**🔥 TechTalk #5** Každá generace má svůj „konec světa“. Někdy to byla jaderná válka. Někdy internet. **Dnes je to AI.** Jedni říkají, že zachrání svět. Druzí, že vezme práci a zničí IT. Realita bývá vždycky někde mezi. Proto tentokrát nechceme keynote ani marketing. Chceme otevřenou technickou debatu o tom, co AI skutečně dělá s vývojem, architekturou a odpovědností za software. **🔥PANELOVÍ HOSTÉ NA ROŠTU:** **🗣️ #1 - [Jan Sládek](https://www.linkedin.com/in/honzasladek/) (CEO [contember](https://www.contember.com/))** **🗣️ #2 - [Michael Žabka](https://www.linkedin.com/in/michael-zabka) (CTO [signageOS](https://www.signageos.io/))** 🗣️ **#3 - [Miloš Čermák](https://x.com/cermak) (novinář v [jednoprocento](https://www.jednoprocento.cz/))** **TÉMATA Z APOKALYPTICKÉ KUCHYNĚ:** 🔥 Budeme **rozumět kódu**, který AI generuje? 🔥 Jak budeme dělat code review něčemu, čemu **nikdo nerozumí**? 🔥 Je **halucinace** stále téma nebo pomalu **zaniká**? 🔥 Security, agent **prompt injection**, úniky kódu a porušování **vlastnického práva**. 🔥 Dříve jsme byli **placení za psaní** kódu; teď jsme **placení za čtení** a kontrolu. 🔥 **Junioři** se nemohou **nic naučit**. 🔥 Anthropic si může napsat **všechen software světa** sám! 🔥 Explozivní růst **technického dluhu** maskovaný produktivitou. 🔥 Tiché **selhávání AI projektů**, o kterých se **veřejně nemluví**. **Podíváme se na to, co dnes AI skutečně dělá s vývojem** – od generování kódu, testů a návrhů architektury přes explozivní růst objemu kódu, kterému už nikdo pořádně nerozumí, až po nový typ technického dluhu maskovaný produktivitou. **Nebudeme řešit, jestli nám AI vezme práci. Budeme řešit, jak se změní odpovědnost za software a jak udržet kvalitu systémů v době, kdy stále větší část kódu vzniká strojově.** Panel bude proložen krátkou technickou přednáškou z praxe: * ⚡ **(překvapení)** 🪢 Celým večerem vás bude opět provázet **[Marek Velas](https://www.linkedin.com/in/marek-velas)** (**[edupunk.cz](https://www.edupunk.cz/)**), který se postará o to, aby diskuze nepřešla v generování náhodných výkřiků a měla spád. \#\#\#\# KDY A KDE: * 📅 **Datum:** Ve středu 20. 5. 2026 * ⏰ **Čas:** 18:30 - 22:00 * 📍 **Místo:** signageOS s.r.o., Evropská 11/2758, Praha 6-Dejvice Těšíme se na setkání!

Learning Czech can be hard and demotivating, especially when studying alone. **This meetup is a shared study session where we come together to stay focused, motivated, and make progress — each in our own way.** This is a co-learning / co-studying session, not a class. There is no teacher, no lesson, and no study material provided. Everyone comes with their own resources and studies independently, in a shared environment. 🧠 **How it works** • We all bring our own material: • textbooks • homework from a Czech course • Duolingo or other apps • reading practice • vocabulary review, etc. • We mainly work individually • We are free to: • ask questions • help each other • share tips and resources • No teacher, no formal structure, no pressure 👥 **Who is it for?** • Czech learners of all levels • Non-Czech speakers (expats, internationals) • Czech native speakers are welcome if they want to help, but this is not a language exchange ⏱ **Practical info** • Location: Cafedu 12, Škrétova 490, 120 00 Praha 2 (Metro A and C, Muzeum station) • Duration: 2 hours, or less or more, as you want • Day & time: Monday, 18:00 • Group size: small group for now • Free event — please support the café by ordering a drink ☕ If you’re learning Czech and lack motivation when studying alone, come join us — let’s find it together 🙂

Ahoj Péhapkáři! Zveme vás na další sraz komunity. 🎤 Anastasiia Kovalova - Když AI agenti narazí na legacy PHP 🎤 Milan Šulc - AI automatizační stack do každé vývojářské rodiny 🎤 Josef Jebavý - Jak dělat frontend backendově 17:30 – open doors 18:00 – přednáška 18:40 – přednáška 19:20 – přednáška 20:00 - kvíz & networking Děkujeme našim partnerům a těšíme se na viděnou! Adresa: Shoptet - Pod Dráhou 1637/6, budova E3, Praha 7 \-\-\- **Anastasiia Kovalova - Když AI agenti narazí na legacy PHP** Co se stane, když AI agenti dostanou reálný ticket v existující codebase, jak nastavit workflow, kontext, validaci a kontrolní body tak, aby jejich výstupy dávaly smysl. (porovnávání Claude Code, OpenCode, Codex) \-\-\- **Milan Šulc - AI automatizační stack do každé vývojářské rodiny** *Pečovatel o open-source webové slony, potápějící se Docker containery a nemocné servery. V Shoptetu má na starost AI — žádný vývojář nebude sedět (bez tokenů) v koutě.* Jeden prompt nestačí. Pokud chcete stavět AI automatizace, které přežijí první demo, potřebujete víc než jen API klíč k LLM. Potřebujete workflow engine, model routing, logování promptů, vyhodnocování odpovědí, ingest dat, klasickou databázi i vektorové vyhledávání. Ukážeme si vývojářský AI automatizační stack postavený na nástrojích jako n8n, OpenRouter, LiteLLM, Langfuse, Firecrawl, Postgres a Qdrant. Projdeme, jakou roli v architektuře hrají, co řeší, co neřeší a jak je poskládat do praktických interních workflow, agentů a automatizací. \-\-\- **Josef Jebavý - Jak dělat frontend backendově** *je cyklista a freediver, který se prvně s programováním a Linuxem setkal již před rokem 2000. Když zjistil, že s počítači jsou problémy, rozhodl se vystudovat informatiku a následně zakotvil jako nezávislý IT specialista. Dlouhodobě se specializuje na: servery, kontejnery v cloudu, webové aplikace a zálohování vše s důrazem na efektivitu testování a bezpečnost. Mezi jeho nejčastěji používané AI nástroje patří Gemini a Cursor.* V posledních letech se při vývoji webových aplikací přechází čím dál více na frontendové technologie. Od nástupu AI a vlny vibecodingu javascriptový frontendový framework automatickou volbou pro webové aplikace. Jednou z několika nejpoužívanějších technologií pro vývoj webu bylo vždy PHP. Od PHP verze 7 se z PHP stal robustním programovacím jazykem a díky dalším nástrojům, jako je PHPStan, výrazně narostla hodnota ekosystému PHP. Podle mého názoru je na tom PHP vývoj aktuálně stále lépe než javascriptové technologie. \-\-\-

As many of you already know [1touch.io](http://1touch.io%2A%2A/) has joined Everpure to combine its AI-driven data discovery and classification capabilities with Everpure’s global scale, accelerating the delivery of next-generation data management solutions. This meetup will be special! **Speaker:** **[Ashish Gupta](https://www.linkedin.com/in/ashishgupta2025/)** - CEO and President of [1touch.io](http://1touch.io/) Ashish drives a bold vision to redefine how enterprises discover, understand, and secure sensitive data in the age of AI. A dynamic and highly regarded technology leader, he brings more than two decades of experience scaling high-growth companies across cybersecurity, enterprise software, and data infrastructure. Prior to joining [1touch.io](http://1touch.io/), Ashish served as CEO of Bugcrowd, where he accelerated the company’s growth, strengthened its market position, and expanded its platform to meet the evolving demands of modern security teams. His earlier leadership roles at global technology companies including Microsoft, Infoblox, Genesys, Actian, and Vidyo reflect a consistent track record of building innovative products, leading high-performing teams, and delivering impactful go-to-market strategies. He now joins Everpure as the General Manager of Data Management. **Talk:** Ashish will talk about why, in today’s AI world, the quality and structure of your data directly impact how well your models actually perform, and why many organizations are still limited by the way their data is set up. He’ll break down why traditional systems fall short and introduce knowledge graphs as a critical foundation for modern AI - connecting data through relationships, not just storing it in isolated tables. Instead of fragmented datasets, you get a connected view: customers linked to purchases, products tied to categories, and patterns that AI can actually understand and act on. You’ll see how this approach brings real-world context into your data, enabling smarter use cases like better recommendations, stronger fraud detection, and more meaningful insights. Ashish will also explain how adding a semantic layer transforms raw data into actionable intelligence, helping AI systems make more accurate predictions by understanding how things relate, not just what they are. If you're working on AI (or planning to) this session will show you why this isn’t just an upgrade, it’s the foundation for making AI actually work. **Time Agenda:** 17:30–18:00 – Doors open and registration with snacks and beer 18:00–19:00 – Talk 19:00–20:00 – Networking time 20:00 – Doors close
