🎓 **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**

**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. Konec pro KMP? * 18:30 3️⃣ Petr Polívka & Alexander Grigorov: Jak (ne)rozbít bankovní aplikaci při integraci KMP? * 19:00 🍕 Networking * 21:00 🔚 Konec akce, jde se domů! 🚫 **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.

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

While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome! Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here. Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings.

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break.

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!

Inspired by our successful events like "Saturday Mornings @ East Market" and other "Pot Luck in the Park" lunches, this gathering promises to be a blend of fun conversations, language exchange, and cultural insights, all while sharing wonderful foods with each other. Please bring a dish to share and anything you would like to drink. We will provide plates, plastic silverware and napkins. So, come hungry and ready to chat!
