**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.

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

**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!

Always an overachiever, David Bayer didn't settle for being Number Two in just about anything. Whether a runaway entrepreneurial success as a teenager, the leading online director for Ducati with over $70 million in sales, or as an early mid-life crisis overachiever with at least three wildly self-destructive behavioral addictions, whatever David did, he did it wholeheartedly. Not surprisingly then, when it came to facing his failures and determining his next course of action, David sought health and healing with the same full-strength effort he had previously used to bring about his own ruination. Seeking to learn from the best of the best, David's pursuit of tangible, practical, actual change from the mind and emotions, outward, brought a new passion--that of encouraging others to learn from his mistakes and to be able to strive after and achieve healing and success in their own lives. We are reading *A Changed Mind*, by David Bayer, and can't wait to enjoy the group discussion on **Wednesday, March 4, 2026, 6:30 pm**, at **True Food Kitchen, Easton Town Center**. Come join us! Get your tickets on [EventBrite](https://www.eventbrite.com/e/a-changed-mind-columbus-ohio-tickets-1978437853879)! Check us out on [Facebook](https://www.facebook.com/events/1390625182655746)!
