Hi all! My name is Cara, and I am a native English speaker from America living in Prague. This a meet up for t**hose learning English as a second language** and want the **opportunity to practice**. It will be a fun and relaxed setting where we will play games to **promote English conversations** or have some kind of activity. This club will meet **every other (two Mondays each month) Monday evening.** The goal is for each person to walk away having learned new English words and have more confidence when speaking in English. Please, bring some money if you want to purchase a coffee from Evento. **This event is sponsored by a church.** The church that sponsors this English meet up is **Církev bratrská, Bohnice** [https://www.cbbohnice.cz](https://www.cbbohnice.cz/) . We want to live lives that are reflective of Jesus. Like Jesus we want to help others in meeting a practical need, in this case that would be speaking in English. At the end of the English club, we will extend an invite to anyone who is interested in exploring faith, wants to know more about Jesus, or wants to meet up to read from the Bible. However, we will never trick you into attending and will always be honest about the content of our meetings. *You do not have to attend religious events to be a part of English Club.*

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 🙂

**Welcome Sci-fi Enthusiasts in Prague!** Our next book pick is Annihilation by Jeff VanderMeer. Thanks to everyone who voted last night. **Summary (from Amazon)** *The Southern Reach Trilogy begins with Annihilation, the Nebula Award-winning novel that "reads as if Verne or Wellsian adventurers exploring a mysterious island had warped through into a Kafkaesque nightmare world" (Kim Stanley Robinson).* Area X has been cut off from the rest of the continent for decades. Nature has reclaimed the last vestiges of human civilization. The first expedition returned with reports of a pristine, Edenic landscape; the second expedition ended in mass suicide; the third expedition in a hail of gunfire as its members turned on one another. The members of the eleventh expedition returned as shadows of their former selves, and within weeks, all had died of cancer. In Annihilation, the first volume of Jeff VanderMeer's Southern Reach trilogy, we join the twelfth expedition. The group is made up of four women: an anthropologist; a surveyor; a psychologist, the de facto leader; and our narrator, a biologist. Their mission is to map the terrain, record all observations of their surroundings and of one another, and, above all, avoid being contaminated by Area X itself. They arrive expecting the unexpected, and Area X delivers, they discover a massive topographic anomaly and life forms that surpass understanding, but it's the surprises that came across the border with them and the secrets the expedition members are keeping from one another that change everything. We look forward to your participation as this should be a thought provoking and enlightening discussion. Reminder, there is a movie adaptation released 2018 is available on Amazon and on Netflix too. Thank you! Alejandra y Richard **Structure** * Book Club starts at 7:00pm and runs through 8:30pm. * Social time from 8:30 - 9:00pm. * No prep needed, just show up with an open mind and heart. * We gather up on the balcony level of the bookstore. * All are welcomed even if you haven't finished the book pick.

**Frontend developers in 2026 are spoiled for choice. New frameworks promising freedom, AI assistants promising to handle the boring parts. But between the framework debates and the quiet burnout, what actually delivers in day-to-day work?** Join us on **Tuesday, May 26**, for an evening focused on the honest reality of frontend development in 2026. Four engineers from Applifting and Mews will share what's actually working—and what isn't—in framework decisions, AI workflows, and the human side of keeping up with constant change. Let's meet in the **Applifting meetup space**, both in person and online. **We’ll start at 18:00.** 👉[ Register here](https://applifting.io/events/frontend-crew-talk-when-tools-move-faster-than-us) 👈 **if you want to attend in person.

PangeAI is building agent-driven geospatial intelligence for anyone, turning natural language queries into instant spatial analysis and decisions, with no GIS knowledge required. Backed by autonomous agents we're focused on use cases geospatial context drive real decisions. We're headquartered in the Bay Area with our European HQ right next door in Prague. Maps encode rich spatial context that today's AI agents largely fail to interpret. In this talk, I'll share how we're teaching agents to "read" maps in production at PangeAI starting with geospatial embeddings as a practical foundation for geo-similarity detection, then layering multi-agentic orchestration on top to generate strategic geospatial insights at scale. Along the way, I'll walk through the tooling and frameworks we've built to make all of this tractable for engineers, with real-world examples and open questions at the intersection of geospatial data and agentic AI. Oh, and the [survey](https://swalgeqfetb.typeform.com/to/UywC1NvW)? Still open — developers only.

Instruction level parallelism by [Ivica Bogosavljević](https://johnnysswlab.com/author/ibogi/) Instruction Level Parallelism (ILP) is the magic ingredient of a modern CPU that makes it run fast. But not all programs are equal, some have more ILP, others have less. In this talk we are going to investigate our codes from the viewpoint of ILP: which code has more ILP, which has less ILP, how does ILP affect software performance and what techniques we can use to speed up our software.

Hi. I would like to set up the first event. This is a space and opportunity to discuss all the things spiritual in a relaxed manner. It is a space where our discussions should bring you joy without any sense of obligation to participate if you don't feel like it. After all bringing just your presence is no small task :) And it's one of the most important things in raising your state of consciousness :) As this is the first meeting it could just be a lightweight conversation or if you feel like we can dive in into more serious fundamental topics. It depends on what are you interested in. It could be: * where are we on the Map of Consciousness (different paradigms) * the nature of our 3D physical reality * nervous system regulation * Biocentrism etc. There's a lot we can talk about and everyone of us has a different level of knowledge and is at a different stage of awareness. Feel free to join and see you there, Daniel

The number of ticks and tick diseases in Ohio have quickly multiplied over the last 10 years. Dean Kreager discusses tick species, tick pathogens, tick-borne diseases, tick bite prevention, and proper tick removal. Kreager is an Agriculture and Natural Resources Educator with OSU Extension in Licking County * Lakewood Public Library (in Hebron)- May 26 at 7pm [https://events.lickingcountylibrary.org/event/tick-talk-29621](https://events.lickingcountylibrary.org/event/tick-talk-29621) * Johnstown public library at 7:00 pm June 8 [https://events.lickingcountylibrary.org/event/ctick-talk-29622](https://events.lickingcountylibrary.org/event/ctick-talk-29622) Free to attend, no RSVP needed

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!
