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

Are you learning Spanish and feel that you need more conversation but are shy to speak? Here you will meet beginners and intermediate and we all will make mistakes in our Spanish communication so it will be just fun! Simply come and enjoy your conversation with the friendly broken Spanish talking group! Sometimes we will meet in some cozy café, sometimes we may go for a walk or some Spanish culture related event. ¿Estás aprendiendo español y sientes que necesitas más conversación pero te da vergüenza hablar? Aquí conocerás a principiantes e intermedios y todos cometeremos errores en nuestra communicación en español, así que será simplemente divertido. ¡Ven y disfruta de tu conversación con el grupo amigable de habla de español roto! A veces nos vemos en algún café acogedor, otras veces podemos dar un paseo o algún evento relacionado con la cultura española. For half of the Spanish here I used translator so if some of the Spanish words above sound weird to you, feel free to blame Google Translate :)

Reproducible dependency management in C++ without sacrificing development velocity by [Alex Vilchanski](https://www.linkedin.com/in/alex-vilchanski-5a3083279/) Ever went back in your project in git history and painstakingly guessed, which versions of the five internally developed dependencies should you even check out to make it compile? Managing dependencies in C++ is still not trivial, especially if you want to build your product with both internal (company) and external dependencies and your goal is to enable fearless dependency management by the not-so-experienced team members. Oh, and you work in an industry that requires you to be able to make patches to old software in reasonable time. Or you just want to bisect that nasty bug, and oh, it's not a monorepo or a super-build project where one can just check out a single revision. Well, I may have something useful for you: a combination of CPM and Conan that should cover most of the teams' needs that usually arise when starting greenfield projects or ecosystems, which is currently the case for me at work. As you've probably heard, many problems are "people" problems, and therefore the presented ideas require fine-tuning and adjustment for your use-case. Since dependency management is an everlasting issue (especially in C++), I also hope to inspire some further discussion in the room and as it often happens, perhaps the audience can suggest further improvements.

Bitcoin Knots a podobné implementace se snaží vynucovat content policy na úrovni mempoolu a odmítají transakce považované za nežádoucí (označované za spam). Lukáš, náš expert na Rust a bitcoin, vám osvětlí tento problém v teorii i v praxi. ** 18:00 - 19:00: PREZENTACE** Tato přednáška vysvětluje, proč je filtrování transakcí na základě obsahu neúčinné v jakékoli vrstvě bitcoinového protokolového stacku. Představí dva vzájemně se doplňující argumenty. 1. Z pohledu topologie sítě: v gossip síti, kde i malá menšina uzlů zůstává permisivní, transakce s vysokou pravděpodobností obejdou filtrované uzly. 2. Z pohledu informační teorie: každý protokol, který je dostatečně expresivní, aby byl užitečný, nutně umožňuje steganografické kódování. Prostor platných transakcí je natolik velký, že do něj lze vložit libovolná data způsobem nerozlišitelným od běžné ekonomické aktivity. Filtrování na základě obsahu tak čelí protivníkovi s větším počtem stupňů volnosti než má samotný filtr. ** 19:00 - 19:30: LIVE DEMO + Q&A** Součástí prezentace bude živá ukázka agresivního relay uzlu napsaného v Rustu, běžícího na mainnetu, která v reálném čase ukáže tok transakcí napříč různými implementacemi uzlů. ** 19:30** **\- 22:00: NETWORKING** Po přibližně 60minutové prezentaci a Q&A zůstáváme na networking u piva, zhruba do 22:00. * **Vstup s registrací zdarma.** * **Pivo zdarma** pro prvních 50 hostů. * **Odměny** za nejlepší otázky. * **Knihy** od Braiins **zdarma**. ** PŘEDNÁŠEJÍCÍ** Lukáš Hozda je expert na Rust, autor knihy Building Bitcoin in Rust a lektor Rust kurzů na Univerzitě Karlově. Přes den pracuje v pražské bitcoinové softwarové společnosti Braiins, kde jeho oficiální pracovní titul zní Braiins Superman. * Stáhněte si jeho eBook [Building Bitcoin in Rust zdarma](https://braiins.com/books/building-bitcoin-in-rust). * Sledujte Lukáše na X: [https://x.com/LukasHozda](https://x.com/LukasHozda) Pokud vás zajímá seriózní Rust engineering, přidejte se k nám. https://braiins.com

**The Prague FrontEnd Meetup is back in 2026!** Join us on **the last** **Wednesday in February, 25th, at 5:00 PM** in the **Ataccama offices in Karlín** for another evening full of inspiration, great talks, and friendly networking. ✨ The lineup: Tomas Belada will be talking about OpenCode - a great open source AI agent. But the real power shows up once you sprinkle a bit of Greek mythology on top. In this talk, I’ll demo a plugin that turns OpenCode into a superpower, an end-to-end coding workflow. Pavel Kepka is experimenting with how the technology stack affects the LLMs - Pavel designed an experiment to evaluate the LLM's architecture decision based on the required technology stack. He'll share his findings and learnings with us at the upcoming Ataccama Meetup. Michal Kopecky will be talking about his MCP-FE library. Michal's annotation says this: Most AI agents are "blind" to your application's internal logic, often relying on messy DOM scraping or raw HTML snapshots. In this talk, I will demonstrate how to bridge React and LLMs natively using the Model Context Protocol. We’ll explore how to give agents direct access to clean component state—such as data grids, active filters, and selections—and enable them to execute actions within the browser. Join me to see how we can transform a simple chatbot into a truly context-aware co-pilot. As always, expect: Snacks & drinks Friendly community vibes Space to learn, share, and connect **RSVP here to save your spot**

**Anotace přednášky:** Naše povídání „AI Fuckupy očima QA“ mapuje cestu od prvotního nadšení z no-code nástrojů a N8N až po tvrdý náraz do reality. Ukážeme vám, co se stane, když se manažerské sny o rychlých úsporách potkají s technickými limity. Zjistili jsme (často draze), že Data Science není Full Stack a že i takzvaný „Judge Agent“ si umí vymýšlet stejně kreativně jako každý jiný agent pracující s daty. Prošli jsme si peklem okolo ROI, bezpečnosti i AI Actu, abychom nakonec našli funkční systém. Ten dnes jasně odděluje testování AI produktů od používání AI jako pomocníka. Doražte. Ukážeme vám, proč AI nemá „God Mode“ a jak ji zapojit do procesu tak, aby vám reálně pomáhala, a ne jen vyráběla drahé problémy. **O speakerech:** **Blanka Fóglová** je QA architektka a konzultantka, která se dívá na testování a delivery proces jako na celek. Pomáhá týmům budovat efektivní QA strategie a automatizaci (včetně Playwrightu či AI QA) s důrazem na to, aby technologie sloužily lidem, ne naopak. Díky zkušenostem z dynamických startupů i velkých korporací dokáže pragmaticky zavádět principy DevOps i moderní metody jako contract testing. **Tadeáš Topol** je Automation QA konzultant a architekt se zaměřením na udržitelný vývoj testovacích frameworků a optimalizaci dodávání procesů. Specializuje se na budování komplexních řešení v nástrojích jako Playwright, Cypress či Robot Framework, které propojuje s reportingem (Grafana, OpenSearch) a výkonnostním testováním v K6. Tadeáš staví mosty mezi QA, vývojem a DevOps, klade také důraz na propojování moderních technologií (včetně AI) s reálnými potřebami byznysu, od dynamických startupů po komplexní korporátní prostředí. Těšíme se - organizátoři [Pro:]Test!

**Ackee meets: Vol. 4 je tady! ** 2026 jsme vyhlásili jako rok Ackee Multiverse. ✨ Ten otevíráme tím největším crossoverem – **Mobile Development. ⚔️ iOS & Android na jednom místě.** Jak dnes v Ackee přemýšlíme o **multiplatformním vývoji**? Svět nejen mobilního vývoje se mění rychleji než kdy dřív a hranice mezi (kdysi rivalskými) tábory se stírají. Přijďte na další Ackee Meets, kde pokecáme o tom, jaké to je, **bořit zdi mezi iOS a Androidem**, jestli **Swift brzy ovládne konkurenční platformu** a jak bezpečně **integrovat KMP do obří bankovní aplikace**. Žádná teorie z učebnic, jen **čistá praxe, fuckupy a zkušenosti** z první linie Ackee projektů. **Kapacita je omezená – registrujte se zdarma přes [Eventbrite](https://www.eventbrite.com/e/ackee-meets-mobile-development-ios-android-tickets-1981931329960).** Interakce tady na meetupu nestačí. **CO NÁS ČEKÁ:** ** Jak jsme v Ackee zbořili zdi mezi iOS a Androidem (z pohledu iOSáka)** *[Rostislav Babáček](https://www.linkedin.com/in/rostislavbabacek/)*, Mobile Developer Jak vypadá přerod kovaného iOSáka v univerzálního mobile developera, který dodává KMP features? ? Podíváme se na dopad každodenní workflow – od boje s cizím IDE, přes rozdíly mezi Swiftem a Kotlinem i mezi Androidem a iOSem, až po dilema, co vše do KMP (ne)patří. Dozvíte se, co nám pomohlo se s tím srovnat a jakou roli v tom hraje správně nakonfigurovaná AI. ** Swift pro Android. Je to konec pro KMP?** **** *[Vít Nademlejnský](https://www.linkedin.com/in/nademlejnskyvit/),* Mobile Developer Apple rozvířil vody založením Android Workgroup a představením Swift SDK pro Android. Znamená to konec nadvlády KMP, nebo jen slepou uličku? Podíváme se na aktuální stav tohoto projektu, jeho limity a reálný význam pro dnešní i budoucí multiplatformní vývoj. ** Jak (ne)rozbít bankovní aplikaci při integraci KMP** **** *[Petr Polívka](https://www.linkedin.com/in/petr-pol%C3%ADvka-5042311b6/) & [Alexander Grigorov](https://www.linkedin.com/in/alexander-grigorov-808751214/), Mobile Developers* Kotlin Multiplatform slibuje sdílení kódu a jednodušší vývoj – pustit ho ale po 2 letech vývoje do rozjeté bankovní aplikace chce odvahu (nebo dobrý plán). Na jaké problémy jsme narazili a co všechno bylo potřeba vyřešit, aby aplikace zůstala stabilní i při takhle masivní změně pod kapotou? Praktické zkušenosti, tipy i slepé uličky z integrace KMP do aplikace se 170 obrazovkami. * ️ **Kdy**: 25. 2. 2026 od 17:00 * **Kde**: Ackee, Block Karlín, 6. patro * ** Za kolik:** Zdarma **Program:** * 17:00 Vstup * 17:30 1️⃣ Rostislav Babáček: Boření zdí mezi iOS a Androidem * 18:00 2️⃣ Vít Nademlejnský: Swift pro Android.

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
