**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**

**PUZZLE CARD WORKSHOP - FREE EVENT - ARTS & CRAFTS!** February 26 Přístav 7, Holešovice (V Přístavu 24) From 7:00 PM Before love notes were instant, they were folded. Carefully. With intention. In the 18th and 19th centuries, people used Victorian puzzle purses to hide poems, romantic messages, and tiny keepsakes — sometimes even a lock of hair — inside beautifully folded paper. You had to open them step by step to get to the heart of it. The idea comes from Japanese Tato origami, and later became a popular (and very personal) way to court in England and America. No envelopes, no seals — just clever folds keeping the secret safe. In this workshop, we’re giving this old tradition a modern life. You’ll make your own puzzle purse using beautiful paper, and turn it into a card, a love note, or a small gift wrapper that actually feels special. No experience needed. Just hands, paper, and a bit of curiosity.

We'll guide you through the rules, and you’ll be scheming, bluffing, and deducing in no time. Come solo or bring a crew — the more, the merrier! **When:** Thursday, 26 February from 19:00 onwards **Where:** Third Coast Pizza Mark your calendars, bring your wits, and get ready for a night of suspense, laughter, and unforgettable storytelling.

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

Filozofování o životě a o všem ostatním pro všechny, bez vstupného a bez přihlášky: Co si přejete, s čím si lámete hlavu, co Vás nenechá spát, o čem dumáte, o čem sníte, co Vám vrtá hlavou, čeho se bojíte, na co vzpomínáte, o čem přemýšlíte? Nenechte tyto věci jen pro sebe, zkuste rozhovor s jinými lidmi. U nás nejde jen o to, si popovídat, o to taky, ale to máte i jinde. U našeho stolu se pokusíme, spolu *filozofovat*. Nejdříve se dohodneme, jaké téma budeme diskutovat, a pak se do toho pustíme, budeme přemýšlet, rozmýšlet, promýšlet a zamýšlet se, až se nám z toho bude točit hlava, přitom nám budou podporou filozofové všech věků, abychom jí neztratili, tu hlavu. Ani byste nevěřili, jak filozofie může být osvěžující…

The brewery also has (passable) drip coffee, free water, and Jeni's ice cream. You can also walk over to the [Land Grant Extension](https://callinyourbluffcoffee.com/) for "real" coffee. (You may have to stand in line, though. The Extension is popular.) You can come late or leave early. Please just sign up so I know to expect you. **Notes on Parking** * You'll (probably) have to park on the street, but street parking is free on Sundays. * There are [parking garages](https://landgrantbrewing.com/parking/) a little farther away if you want. These are obviously not free, though. * There is a [lot next door](https://www.google.com/maps/place/39%C2%B057'26.0%22N+83%C2%B000'40.9%22W/@39.957211,-83.0119921,19z/data=!3m1!4b1!4m12!1m7!3m6!1s0x88388f3efd89238b:0xc139207386232411!2sLand-Grant+Brewing+Company!8m2!3d39.9577613!4d-83.011426!16s%2Fg%2F1pzt7t9df!3m3!8m2!3d39.957211!4d-83.011347?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) to the brewery that you're allowed to park in, but it is not free. I've never parked there, so I don't know anything about rates. (I'm told though that if you eat at Milo's Deli next door to this lot that Milo's will stamp your parking so it's free.) * You're going to see odd signs on [Lucas St](https://www.google.com/maps/place/39%C2%B057'26.1%22N+83%C2%B000'40.3%22W/@39.957256,-83.0124134,19z/data=!3m1!4b1!4m10!1m5!3m4!2zMznCsDU3JzI4LjgiTiA4M8KwMDAnNDEuNSJX!8m2!3d39.957993!4d-83.011536!3m3!8m2!3d39.957256!4d-83.011197?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) (saying it's a "private street") that will lead you to believe you're not allowed to park there, but you actually are. * Columbus parking cops literally do not work on Sundays. This means that, even if you're driving a non-EV, you can park in the EV spots near the brewery. **Games** I do bring many games, but please bring some of your own as well.

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries.
