**Léto klepe na dveře a před námi je poslední pražský předprázdninový meetup. Než začnete se svým agentem řešit, kam na dovolenou a co si vzít s sebou, a vyměníte prompty za offline čtení na pláži, stavte se pro poslední dávku nápadů! 🤖☀️🔥** Pohodový večer, kde to nebude o tom, že nás AI nahradí, ale o tom, co s ní reálně zvládneme líp. Jako vždy odstartujeme Nowwwinkami a pak se ponoříme do programu, který stojí za odložení dovolenkových plánů o jeden večer. Přijďte si pro poslední nálož inspirace, než pošlete své agenty na virtuální pláž a všechno utichne v dovolenkovém a okurkovém režimu. ☀️🏝️🥒 **Hlavní line-up** 🤩 * 🟢 18:00 otevíráme dveře v **CDN77** * 1️⃣ 18:30 **Nowwwinky** od Tomáše Kouta * 2️⃣ 19:00 **Mezistavy: React nechce, abyste řešili async** od Adama Kováře * 3️⃣ 19:30 **Vibecoding 280+ dní poté** od Jana Honzy Černého a.k.a. chemiXe * 4️⃣ 20:00 **Co mi chybí v** **BEM** (lightning talk) od Jirky Cerhana * 🎓 80+ nadšených účastníků * 🍻 a v neposlední řadě kvalitní networking \-\-\- 1️⃣ Tomáš Kout se svými **Nowwwinkami** jako obvykle otevře večer svým přehledem toho nejzajímavějšího z poslední doby. \-\-\- 2️⃣ Následuje přednáška na téma **Mezistavy: React nechce, abyste řešili async** od [Adama Kováře](https://www.linkedin.com/in/adam-kov%C3%A1%C5%99-0905a0169/) z [CDN77](https://www.cdn77.com/) Většina interakcí v UI je asynchronní, spinner browser tabu nám už nestačí a frameworky stále hledají řešení. Odpověď React teamu je, že async řešit nemusíte, alespoň ne tak jako doposud. Ukažme si, jak toho chtějí docílit pomocí transitions a action patternu. Adam o sobě: *„Mám rád otevřený a rychlý web, přesto posledních 6 let vyvíjím v Reactu. Věřím, že RSS je technologie budoucnosti a ve volném čase luštím křížovky.“* \-\-\- 3️⃣ Přednáškový blok uzavře [Jan Honza Černý a.k.a. chemiX](https://www.linkedin.com/in/chemix/) příspěvkem **Vibecoding 280+ dní poté** ...a pak přišel vibe coding. Najednou stačilo pár vět do chatu a před očima začaly vznikat funkční prototypy rychlostí blesku. Jenže to nebyli jen prototypy. CEO, manažer, grafik dostali nástroj kterým začali plevelit codebase a vibecode apokaplypsa začala... Tato přednáška ukáže, co jsme se za více jak 280 dní naučili. Jak s apokalypsou bojovat. Jak předcházet nakažení. Jak se bránit proti nákaze. A jaké jsou příznaky nakažení nejen kódu, ale i u lidí. To celé trošku s nadsázkou a hlavně otvírákem k diskuzi u piva. Jan o sobě: *„Digitální alchymista – rád zkoumá substituce UX, UI, AI, frontendu i backendu. Všude i nikde. Offline mísí s online. Tam, kde klávesnice končí, začínají kostky a karty. Spoluorganizátor technických meetupů po celé České republice, klid hledá u rydel nebo v lese.“* \-\-\- 4️⃣ A na závěr v odlehčeném duchu naservírujeme lightning talk na téma **Co mi chybí v** **BEM** od [Jirky Cerhana](https://www.linkedin.com/in/jiri-cerhan/) ze [SiteOne](https://www.siteone.cz) BEM metodiku pro organizaci CSS většina z nás důvěrně zná. Ve své praxi jsem ale narazil na pár míst, kde to maličko skřípe. S nástupem CSS custom properties se nabízejí nová řešení, která posunou přehlednost a snadnou modifikaci komponent o úroveň výš. **Máte zájem se připojit do bloku ⚡️Lightning talk(s) taky?** Napište a zajistěte si své místo ještě na této akci. \-\-\- Neváhejte s registrací a zabookujte si místo – bude to stát za to! 🎉 👉 Pro další zajímavé novinky a dění sledujte kanály komunity na [Youtube](https://www.youtube.com/@FrontendistiCz), [X](https://x.com/Frontendisti), [Facebooku](https://www.facebook.com/frontendisti/), [Instagramu](https://www.instagram.com/frontendisti/), [LinkedInu](https://www.linkedin.com/company/frontendisti/posts/?feedView=all) nebo navštivte [náš web](https://www.frontendisti.cz).

**🎟️ REGISTER [HERE](https://luma.com/mewsrnd-whenaileavesthelab) TO SECURE YOUR SPOT AT THE EVENT 🎟️** Frontier AI models are evolving quickly, but the real challenge is no longer just building larger systems, it is turning advances in LLM research into reliable, efficient, and valuable products in the real world. ​ We invite you to join a panel discussion featuring experts working across AI research and engineering, who will share their perspectives on what actually matters in the next wave of LLM development. The conversation will explore the trade-offs between scale, efficiency, reasoning, and product impact, as well as what it takes to move from experimental models to systems that can be deployed at scale. The discussion will be moderated by **[Rogers Leo](https://www.linkedin.com/in/rogersjeffreyl/?utm_source=luma), Director of Engineering and Product (Agentic AI) at [Mews](https://www.mews.com/en?utm_source=luma).** ​This panel will go beyond the hype and focus on practical lessons from building with LLMs today. We will look at where current approaches break down, what “good enough” really means in production, and why efficiency and system design may matter as much as model capability. ​ **Panelists:** **[Karol Lasocki](https://www.linkedin.com/in/karol-lasocki-1a86b2151/?utm_source=luma)**, Senior Machine Learning Engineer at **[BottleCap AI](https://www.bottlecapai.com/?utm_source=luma)** **[Luděk Matyska](https://www.linkedin.com/in/ludek-matyska/?utm_source=luma)**, AI Lead at **[ROUVY](https://rouvy.com/?utm_source=luma)** **[Soheyla Mirshahi](https://www.linkedin.com/in/soheyla-mirshahi-phd/?utm_source=luma),** AI Governance & Product Leader at **[T-Mobile](https://www.t-mobile.com/)** ​**Agenda:** 18:00 Doors open 18:30 Panel discussion + Q&A 19:30 Networking **🎟️ REGISTER [HERE](https://luma.com/mewsrnd-whenaileavesthelab) TO SECURE YOUR SPOT AT THE EVENT 🎟️** \-\-\-\-\-\- Photographs and video recordings may be taken during this event for documentation and promotional purposes, including use on websites, social media, and other communication channels.

We are a group of runners who meet most weeks for a run around the beautiful Vltava River's edge. You can bring your running shoes straight from the office/home office if you don't have time to stop at home. There will be a place to put your bags in the Cafe. We will run about 9 km along the river and have a drink afterwards. Paces vary! We will meet in the square near Kavarna Liberal (Hermanova 6), near the Vltavska metro/tram stop at 6:30 on Wednesday. See you there!

In this workshop you will learn to make your own mini (25×25) or small rug (30×40) from scratch! No experience needed and all material provided.

Budeme rádi i za méně pokročilé příspěvky, protože většinou jsme velmi hluboko v technických detailech. **Lokalita:** Fyzicky v Microsoftu v Praze Vyskočilova 1561/4a, Praha 4, 140 00 Místnost Morava Případně online na [https://ppug.community/stream](https://ppug.community/stream) **Jazyk:** čeština **Agenda:** [https://ppug.community/agenda](https://ppug.community/agenda) **Přihlašte vlastní příspěvek:** [https://ppug.community/sessions](https://ppug.community/sessions) **Link na stream:** [https://ppug.community/stream](https://ppug.community/stream) **Občerstvení:** Bagety **Úroveň:** 100-300 Tak si prosím naplánujte čas ve svých kalendářích a přijďte, pokud bude chuť a čas, tak si po meetupu určitě můžeme sednout na pivo.

Welcome to the international Café Philo in Prague. We meet every first Saturday of the month in the cosy [Café Millème](https://store11473398.ecwid.com) in the center of Prague. We choose a participant randomly, by lottery, who then has the privilege to determine the topic of our discussion. We will reflect, ponder and exchange arguments until our brains are on fire. Philosophy isn't just something for universities, it is a way to open your mind to new thoughts and questions. No application is necessary, there is no entrance fee and there are no prerequisites for participating, except curiosity and respect for other people. We meet from 17:15 until 18:45 to follow together the white rabbit into the wonderland of philosophy... More information about me under this [link](https://sophonautik.ch/english/).

Kromě konference jsme připravili ještě novinku. Nemáte čas být celý den na konferenci? Po konferenci bude navazovat večerní setkání Apple fandů. Jako hlavní téma jsme vybrali chytrou domácnost, ale bavit se můžeme o čemkoli. Pokud máte čas, můžete to spojit s konferencí a udělat si takový poctivý iDen. Pokud ne, můžete přijít jen na večerní část. Informace, program a přihlášku najdete na: https://ipure.cz/ipure-setkani-fandu-smarthome-2026/ S kódem MU30 opět 30% sleva

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…

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
