Are you learning English as a second language and looking for a chance to practice? Join our **English Conversation Club**! We create a friendly atmosphere with **games and activities** designed to help you improve your conversational skills. Our goal is simple: **leave each session with new words and more confidence speaking English!** **Details:** * **Cost:** Free (bring some money to buy a drink at Tichá Kavárna) * **Frequency:** Meets regularly based on attendance * **Who:** Anyone studying or practicing English **Things to know:** Tichá Kavárna is a social enterprise café that creates jobs for the deaf community and connects the hearing and deaf worlds. Guests can order in sign language or simply point to the menu, making communication easy. Profits support services for the deaf and the café’s development. This event is sponsored by the church **Církev bratrská, Bohnice** [https://www.cbbohnice.cz](https://www.cbbohnice.cz/). We believe in helping others with practical needs—like learning English—while we live lives that reflect Jesus. At the end of each session, we’ll offer an open invitation for anyone interested in exploring faith, reading the Bible, or learning more about Jesus. **Participation in religious activities is completely optional.** We will never trick you into attending and will always be honest about the content of our meetings.

**Hosted by Pure Storage** Please note at the Pure Storage office, all meetup attendees will be required to sign a generic NDA used for all office visitors to be able to attend the meetup. Doors are open from 17:30, talks will start 18:00, and we have 2 talks and panel discussion. **1\. Daniel Turecek \(Pure Storage\) \- What is new in Go 1\.26** In this lightning talk, we’ll tour what’s coming in **Go 1.26** (based on the current draft release notes) and why it matters for real-world services. We’ll cover runtime and performance wins like the default **Green Tea GC**, faster **cgo** calls, improved stack allocation, and new profiling options aimed at spotting goroutine leaks. We’ll also look at security and crypto upgrades including 64-bit heap address randomization, the new **`crypto/hpke`** package, and **post-quantum hybrid key exchange on by default in TLS**. Finally, we’ll touch on pragmatic developer-experience changes—from `new(expr)` and richer generics constraints to tooling updates like `go fix`, `pprof` flame graphs by default, and compatibility-oriented module defaults. **2\. Vilibald Wanca \- Nail the Basics \- S01E02** Good Go code starts with a simple, predictable layout. In this talk, we’ll cover the standard approach to structuring Go projects: keep things flat early on, map one package to one directory, and keep tests right next to the code they validate (like `user.go` and `user_test.go`). We’ll also look at common structural mistakes—such as over-engineering too soon or importing Java/Python-style layering that fights Go’s package model—and how to avoid them. Finally, you’ll leave with a handful of quick wins you can apply immediately: formatting and import automation with `gofmt`/`goimports`, stronger feedback loops with `golangci-lint`, and editor setups (VSCode Go extension or GoLand) that make the “Go way” feel effortless. **3\. Panel discussion with our speakers on AI tools and Go development** Join us for a panel discussion with our speakers on how AI tools are changing Go development in practice. We’ll compare real workflows for using assistants to design, code, test, refactor, and review Go services—what actually saves time, what introduces risk, and where humans still need to stay firmly in the loop. Expect practical tips on prompt patterns, maintaining code quality, avoiding “AI-shaped” over-engineering, and integrating AI into existing tooling like linters, editors, and CI. Bring your questions—we’ll keep it candid, concrete, and Go-focused.

We’ve got another portion of AI talks for you, so come to our second Prague Gen AI Meetup of the year. ## NEW VENUE (very important) **Pracovna & Laskafe** Vlkova 628/36, 130 00 Praha 3-Žižkov ## Venue Schedule * **18:30** Doors open * **18:45** Talks start * **20:45** Talks end * **21:00** Snacks and beer ## What’s On The Agenda * **Talks:** Again, no hype, just the stuff you want to know. * **Snacks and Beer:** Grab a bite and a brew while talking shop. * **Networking:** Meet other people in the field. No fluff, just good tech talk. ## Talks ### Šimon Podhajský (Head of AI @ Waypoint) **The Eval Flywheel: From "Works on My Laptop" to Systematic Quality** Most teams shipping GenAI products have no evaluation system. They have vibes, a few saved prompts, and hope. This talk doesn’t start with “build an eval suite”, it starts with **observability**: if you can’t see what’s happening in production, nothing else matters. From there, we build the **eval flywheel**, a practical pattern where production observability feeds error analysis, error analysis generates eval cases, and eval cases prevent recurrence. Your evaluation suite isn’t something you design upfront, it’s something that grows out of understanding your production failures. ### Ondřej Romancov (Engineering Lead @ Duvo.ai) **Building agents with agents** Duvo is building a platform for AI agents, and we’re running our engineering on agents too. Sharing practical tips and workflows we’ve found useful along the way. Let’s get down to the real talk.

In a world full of opinions, noise, and quick reactions, we often miss spaces for real dialogue — for slowing down, listening, and connecting with one another. This evening is an invitation to do exactly that. Join us for an open and friendly evening (in English & free of charge) dedicated to Automated Commonwealth (UBI - Universal Basic Income), can we use AI for people's welfare? Is it a basic income what we really need? We will brainstorm together in an Open Space–style format, where participants choose topics themselves, and what we want to discuss from this broad topic - questions to help you get inspired: Is it possible to achieve automated UBI? Is UBI what we need, or is it better social infrastructure? How do we start building such system? Afterwards, participants will form small groups to explore the questions and insights around the topics 18:00 – Doors open 18:15 – Introduction & topic selection 18:40 - We start discussions 19:40 - Closing session (sharing activities) 20:00 - Networking & Connect What to expect: A welcoming space for newcomers and regulars alike Be slightly pushed to socialise Open, participant-led small-group discussions on diverse perspectives No expertise required — everyone’s opinion matters! Safe, respectful, and judgment-free conversations More about sharing and reflecting than debating or convincing No pressure to speak — listening is just as valuable Not a lecture, not a debate club, and definitely not intimidating! Feel free to bring some snacks to share! Friendly dogs are welcome! If you are a regular that appreciate us and can help, or a newcomer who enjoyed the evening, and wants to help, we have recently set a patreon page where you can support us! https://www.patreon.com/cw/EarthSocietyDialogues

Would you like to know more about the tantric approach and add more depth to your sexual life but don’t know where to start? Would you like to deepen the relationship with yourself or with your partner? Or maybe you just want to be able to talk about these topics openly with like-minded people? I created Eros Reading Circle because I believe erotica nowadays is very misunderstood. Fast satisfaction is the preferred way on societal level. There are plenty of negative emotions – shame, guilt, low self worth – attached to the topic of pleasure in the collective and also on the individual level. The past few years I dedicated to self-exploration and the broadening of my horizon when it comes to depths of pleasure and living the tantric approach. We gather every three weeks in a cozy tearoom in the heart of Prague (near I.P. Pavlova). You don’t need to join every time. You can attend only one session or more – each time we will cover a different topic. We don’t read full books. When you book your spot, you will receive an email with the text for the upcoming circle and 2-3 reflection prompts. We usually cover one chapter, 10 to 30 pages (written in English). You are asked to read the chapter before the session. All genders, singles and couples are welcome. Our readings explore erotica, pleasure, tantra, ecstasy, desire and the polarity of masculine and feminine energies. Some sessions focus on men’s sexuality, others on women’s, and some on pleasure as a whole. During each circle, we begin with a short grounding practice, share what resonated or didn’t, engage in discussion and end with a closing reflection. Eros Reading Circle is for you: - If you are desiring to have a more conscious sexual life - If you want to deepen your relationship to self (and to your partner) - If you would love to attract a partner who complements you - If you would like to connect and exchange ideas with like-minded people - If you want to experiment with new practices, try new things - If you would like to leave behind negative imprints attached to your sexuality - If you are interested to learn about pleasure from a more spiritual or philosophical aspect - If you have wondered what tantra is and how could you apply it in your own life - If you would love to join a circle of book lovers but can’t commit to reading long books When? 19th February, 19.00-21.30 Where? Čajovna Šamanka How much does it cost? 350 CZK Facebook event link: https://www.facebook.com/share/1GBTAgfZRP/?mibextid=wwXIfr You can book your spot after clicking to the below link: https://buy.stripe.com/14A3cu2CJ8g40dZ7Uh5Ne08 If you cancel with more than 24 hours’ notice, you can reschedule within three months.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

# **Band: Old Possum's Menagerie; Caller: Richard Ades** Beginner lesson at 1:30, regular dancing begins at 2:00 pm NOTE THAT WE ARE TEMPORARILY DANCING IN THE AFTERNOON INSTEAD OF EVENING. Dance with us in the afternoon then you can still go out in the evening! **Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 1:30 - 2:00, followed by dancing 2:00 - 430. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. Please bring your own refillable water bottle.

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.
