**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.

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 :)

**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.

Open philosophical discussion, thinking together about a topic in a philosophical way. The topic will be chosen by the participants at the beginning of the event. No application, no entrance fee. (But as we are meeting in a normal coffee shop, you have to order at least a cup of coffee or tea.) Experience the joy of real dialogue with other people about the really important topics of life! Follow the white rabbit into the wonderland of philosophy... You find informations about me and the event [here](https://sophonautik.ch/english/). Je nach Gruppe kann die Veranstaltung auch auf [Deutsch](https://sophonautik.ch/deutsch/) abgehalten werden.

Join us for Symposium! 🌞🌻🌳 In antiquity, a symposium was a gathering of friends who came together to recline around a shared table, where wine and conversation flowed freely into the night. Together, they would choose a topic and take turns speaking, listening, and laughing—guided by the rhythms of drink and dialogue. Inspired by this tradition, our Symposium has no set theme. It's an invitation to come together with other curious minds, to offer up questions or ideas, and to vote together on where to begin. Whether you're hungry for connection or simply seeking space to speak and be heard, you're warmly welcomed to join the conversation. Symposium will meet in parks throughout Prague, embracing the sunshine and pleasant weather while we have it. Bring a blanket or something to sit on. There’s no cost to join, but please bring a snack or drink to share, if you're able. Most of all, bring a curious mind and a willingness to learn from the insight of others. Feel free to bring a friend or two--also, children and friendly dogs are welcome! \*\*\* If the weather doesn't cooperate, we'll try to find an alternate venue—so keep an eye on the event chat or your email for updates. Also, despite the origins of the Symposium, our goal is not necessarily to get drunk and the organizer would encourage you not to come with that sole purpose in mind. :) The first 45 minutes of the event will be dedicated to simply getting to know one another, and we highly encourage you to join for this part. We will then vote whether to continue free conversation, to join together in a single conversation, or to split up into multiple groups. Afterwards, you’re welcome to stay or follow onto any spontaneous activity that unfolds. A note on attendance: If you need to cancel, please do so at least a few days in advance and update your RSVP accordingly. This helps honor the host’s efforts and makes space for others who would like to attend. Repeated last-minute cancellations or no-shows may result in being placed on the waitlist for future events.

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)**

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/).

Hello ladies, Another meeting is here 🎉 Would you like to get to know other women who are interested in IT or work in the field? Let's build a community together, meet & get to know new friends, and talk about everything and anything. This time we may meet outside 🌳 But it depends on weather so check out this event few days before it's happening for more precise location. Looking forward to seeing you! 😊

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.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!

This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
