Join us for the first Symposium of the season to usher in the coming of Spring! 🌞🌻🌳 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.

This group is for anyone who writes - for any reason. Have a thesis or article you need to write? Trying to finish a novel or an academic paper? This group is for you.

At the end of the session, you can give us a brief recap of how it went. We'll break at noon. The afternoon session starts at 2:00 pm. You're welcome to join both sessions or just one. Please come as close to 9:00 as you can if you come for the morning session. If you come to the afternoon session, we are usually back by about a quarter to 2:00.

Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun.

Join us for a relaxed **Saturday co-work session** where we simply sit together, work on our own things and enjoy the company of other women doing the same. ☕ It doesn't have to be AI related at all, though it absolutely can be!

Sometimes all we need is a little accountability and a warm space to finally make progress on the things that matter to us. 💜 See you there! :)

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.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
