**Would you sacrifice one innocent life if it guaranteed happiness for everyone else?** This is one idea we will discuss at the next Read & Riff meeting, where we'll dive into **Ursula K. Le Guin's short story ‘The Ones Who Walk Away from Omelas.’** **Read & Riff is a book club for short story lovers.** We come together to share what we loved, hated, questioned and everything in between about a selected story. Read the selected story in advance, then join Debbie (your host) who will bring questions to guide the discussion and keep the conversation flowing. **There are no experts, no homework beyond the reading, and no right answers. Just good stories and even better conversations.** Join us! **Date:** 3 July 2026 **Time:** 18:30 - 21:30 **Place:** Nerd Alert, Bulharská 924/26, 101 00 Praha 10-Vršovice **Fee:** 50czk per person Story: ‘The Ones Who Walk Away from Omelas’ by Ursula K.

**The most enjoyable way to meet new people without going clubbing! ✨** Tancheerna is unlike any dance event you’ve ever been to—there are no complex routines or staring at your feet. We hit the play button at 19:00 and start right away with fun group dances that are so simple, even children can do them. Later we blend in some easy couple dances mixing European classics, modern folklore, and smooth Latin rhythms. Our evenings are all about **great music, laughter, and the simple joy of moving together.** You don’t need a partner or any dance experience to join us. As long as you can sway to the rhythm, you belong. We use fun group mixers and rotate constantly, making it the perfect, fresh way to come alone and **connect with everyone naturally**. At 21:00, we wrap up the music and head to the nearby bistro for drinks and socializing. 📍 **Vítkov**: https://maps.app.goo.gl/JqyW62aohn18g5ZB8 **🕒 THE PLAN:** 18:50 - Arrival & Hellos **19:00 - The Music Starts! 🎶** 21:00 - Socializing at Bistro Vítkov 🍻 🎟️ **FREE ENTRY** 🌤️ **Weather Note:** This is an OPEN-AIR event! We dance only if the weather is nice.. 👟 Wear comfy sneakers or go completely barefoot. Pack a water bottle to stay hydrated and a hoodie when the sun goes down. Tančírna (pronounced tahn-cheer-nah) comes from the Czech word "tančit" (to dance) and literally means "a place for dancing". If you love to move and want to make new friends, simply show up on Friday and let’s dance!! 💃

Join us for a slow Sunday morning coffee, real conversation, and meaningful connection at Crunch in Žižkov. This is a space for people who want to meet others in a more present, human, and grounded way. No awkward networking energy. Just coffee, conversation, and a chance to hear each other beyond job titles. We will gather at 10:00 am. Grab a coffee, and if you feel like it, you can also have breakfast. Together, we will explore simple questions like: \- Where are we in life right now? \- What are we building\, creating\, changing\, or dreaming about? \- What kind of support would feel helpful? \- How can we help each other\, connect each other\, or simply witness each other? The intention is to create a warm space where we can meet as whole humans, not only through what we do for work. Whether you are an entrepreneur, creative, coach, founder, freelancer, corporate professional, artist, multipassionate soul, or someone in transition, you are welcome. Come as you are. Bring your curiosity, openness, and willingness to connect in a real way.

Dear Adventurers, This one is truly special! Our dear friend and a relentless hiker Honza is taking us on a night adventure through Krkonoše where we'll get to see both the sunset and sunrise in one go. In between, we'll enjoy a ridge walk free of noise and light pollution (unless people opt for headlamps 🙃), and a picnic or two under the starry sky. ⚠️ The pace will be moderate, but the trail is still almost 40 km with significant elevation gain/loss. Not to mention the dark. Brace yourself for hills, uneven rocky paths, and circadian rhythm confusion. 📍 **Trail** 38 km • ↑ 1381 m • ↓ 1381 m [MAP OF THE TRAIL](https://mapy.com/s/betagekuta) **🚌 Travel** → We'll drive (Honza and Thomas).

**These are the hottest days of the year. We will meet on the 4th of July at the entrance of the Planetárium Praha ([Královská obora 233, Bubenec, 170 21 Praha 7](https://www.google.de/maps/place/data=!4m2!3m1!1s0x470b94ce6ef24a2d:0x95d62e70e8497a61?sa=X&ved=1t:8290&ictx=111)).** **From 17:00 until 17:15, we will gather in front of the planetarium. After 17:15, we shall then start searching for a nice place under the trees, where we will discuss, eat and drink together until the night…** **If you like to have a philosophical conversation while enjoying the magnificent surroundings of the Stromovka Park, come and join us, the only condition for joining is that you bring something to eat and to drink with you. We will put all the delicious things on a blanket so that we don’t exchange only arguments…** **Even though I normally don’t determine a topic in advance, I would like to ask you this time to make a list of some of your favorite movies. Try to imagine you have to convince another person that these movies are great. What would you say? What makes these movies important for you? What important (philosophical) questions do these movies raise or maybe even answer?**

You went on that retreat, read the book, committed to meditating daily. And here you are at 3 am, drunkenly staring down a Žižkov doner, wondering what happened. Come share your spiritual misadventures. You can bring a story, poem, insight, or simply come and hang out. This is a space for anyone interested in spirituality and meditation. All paths and experiences are welcome! We are meeting at Stromovka Park, near Stromovka Fountain. Bring something to sit on. Pets are always welcome! We’ll start with an opening circle, short group meditation, then move into sharing and discussion. If you arrive while we're meditating, feel free to join us quietly.

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.

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.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
