Are you learning Spanish and feel that you need more conversation but are shy to speak? Here you will meet beginners and intermediate and we all will make mistakes in our Spanish communication so it will be just fun! Simply come and enjoy your conversation with the friendly broken Spanish talking group! Sometimes we will meet in some cozy café, sometimes we may go for a walk or some Spanish culture related event. ¿Estás aprendiendo español y sientes que necesitas más conversación pero te da vergüenza hablar? Aquí conocerás a principiantes e intermedios y todos cometeremos errores en nuestra communicación en español, así que será simplemente divertido. ¡Ven y disfruta de tu conversación con el grupo amigable de habla de español roto! A veces nos vemos en algún café acogedor, otras veces podemos dar un paseo o algún evento relacionado con la cultura española. For half of the Spanish here I used translator so if some of the Spanish words above sound weird to you, feel free to blame Google Translate :)

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 🙂

**Greetings Sci-fi Enthusiasts in Prague!** Our June 2026 book pick is, *This Is How You Lose the Time War* by Amal El-Mohtar & Max Gladstone. Thank you to everyone that attended in May and voted on our book selection. Among the ashes of a dying world, an agent of the Commandant finds a letter. It reads: *Burn before reading.* Thus begins an unlikely correspondence between two rival agents hellbent on securing the best possible future for their warring factions. Now, what began as a taunt, a battlefield boast, grows into something more. Something epic. Something romantic. Something that could change the past and the future. Except the discovery of their bond would mean death for each of them. There's still a war going on, after all. And someone has to win that war. (description via Goodreads) Shout out to everyone that attended our book club in May and voted for our book selection. 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.

The perfect code doesn't exi... by Martin Hořeňovský Perfect code doesn't exist, right? There are always tradeoffs, complications and hidden complexities in the way. At least until now. I wrote the perfect C++ function, and I'll show it to you. What's more, I'll prove it to you, using all the different automated tools and approaches we commonly rely on during development: compiler warnings, static analysis, code coverage and others. In practical terms, I will showcase various tools we use during development; what issues they can catch, what issues they do catch, and why they protect us from Murphy, but not Machiavelli. Timetable: 18:00 Get together, setup, socialize 18:30 talk starts ??:?? talk ends, more socializing For those who want to join online here is the **[ZOOM LINK](https://us06web.zoom.us/j/87626916146?pwd=tE0xBia9Mnd8t2IGshtNpwyekQ9Zle.1)** While you wait why not join our **[DISCORD SERVER](https://discord.gg/EPMXNGuHXG)**

**Anotace přednášky:** AI nástroje píšu kód rýchlejšie ako kedykoľvek predtým. No rýchlosť bez kontroly kvality je len technický dlh vo väčšom meradle. V tejto prednáške sa pozrieme na to, ako LLM skutočne fungujú, ako inteligentne pracovať s kontextom a ako z AI dostať konzistentný, kvalitný výstup. Ukážeme si, ako používať AI na písanie testov, a prečo je verifikácia kódu kľúčová pre tímy, ktoré sa na AI pri vývoji výrazne spoliehajú. **Čo si odnesieš:** * Pochopíš, ako LLM a AI agenti skutočne fungujú pod kapotou * Naučíš sa pracovať s kontextom tak, aby si z AI dostával lepšie výsledky * Zistíš, ako písať čisté testy pomocou AI * Pochopíš, prečo je verifikácia nevyhnutná, keď AI píše väčšinu kódu **O řečníkovi:** Filip Hric začal svoju kariéru tým, že zdieľal to, čo sa naučil o testovaní. A nejako sa to rozbehlo. Jeho blog prekročil 2 milióny prečítaní, jeho kurzy absolvovali tisíce vývojárov a testerov a stal sa jedným z mien, na ktoré sa ľudia v oblasti testingu a quality engineeringu odvolávajú. Dnes spolupracuje s vývojovými tímami na tom, ako zabudovať kvalitu priamo do ich procesu, vystupuje na konferenciách po celom svete a snaží sa, aby éra AI nebola strašiakom pre tých, ktorým záleží na softvéri, ktorý naozaj funguje. Žije na Slovensku so svojou ženou a štyrmi deťmi. Beháva a hrá na gitare. Těšíme se - organizátoři [Pro:]Test! **POZOR**! Meetup probíhá na adrese: **Lihovarská 1060/12, 190 00 Praha 9-Balabenka**, NE v sídle Accentura na Holešovicích. **Setkání probíhá osobně na místě bez streamování.

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/).

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. 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 sponsored the Dianetics & Scientology Self-Improvement Center.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
