We'll have another session with talks. The main topic will be about Safe Scala and DAPR. Safe Scala is a subset of the Scala language which strictly enforces the discipline of tracking all effects via Capabilities. It was originally pitched by Odersky as safe way to let AI agents write code, since they can't just run arbitrary code from JDK nor do side effects in general. But it may have seemed thus as a purely academic exercise. This is where DAPR comes in. It's an innovative cloud runtime from Microsoft, which lets programmers focus on writing business logic. The rest, like wiring up service calls, queues, handling retries or managing state is delegated to a language agnostic sidecar container. The point of the presentation will be to prove that if we represent individual aspects of DAPR as Capabilities, we can write apps in Safe Scala. We will prove that Safe Scala can actually be practical choice for writing typical cloud (micro-)services. We'll also have a round of lightning talks. This event is sponsored by [Pure Brew](https://purebrew.tech/)

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 🙂

**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.

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.

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!
