Description: Meet us by the Powder Tower, the historical gate to the Old Town and starting point of the Royal Route. Then have an educative walk through the narrow and picturesque streets of the historical center of Prague. Enjoy the unique diversity of architectural styles from Gothic to Art Nouveau. See some of the most interesting sites and get to know fascinating facts and legends of the 1000-year old capital of Bohemia. End the tour at the riverside 5 minutes away from the Charles Bridge, from which you can continue the tour on your own (or again with us) towards Malá Strana or Prague Castle. ====== Meeting point: We will be standing by the Powder Tower at the side of the Namestí Republiky square with a green umbrella in hand :) Map: https://goo.gl/maps/tzqKpZ2945S2 Price: there is no fixed price, you will be able to decide yourself how much you value the tour. If you don't know how much is best (and can afford it) we recommend 200Kč, but it really depends on you how much you contribute. Join us also on our [Facebook profile](https://www.facebook.com/freewalkingtoursprague/) :) and if you are travelling to other cities check out our friends at the [Free Tour Community website](https://freetourcommunity.com/). For any questions, please contact us at info@freewalkingtourprague.eu. Unfortunately, the meetup application does not always send us phone notifications. Reminder - only people who booked on our [official free walking tour website](https://freewalkingtourprague.eu/en/schedule) can join the tour and if the tour shows fully booked on the website it means there are no free spots. The meetup list doesn't count in this case. We look forward to meeting you, Michal, Amanda, Lana, Iva & Chris

Are tomatoes destroying the planet? Join me to find out. Depending on attendees preferences this event will take either a more hands on approach to the diversity and quality catastrophe that we see in shops regarding our beloved vegetables, or a more chill attitude. Economic or social aspects can be covered, again depending on the democratic preferences of the attendees. If it wouldn't be for the depressing landscape of the situation it would be a fun event. This way the most suited style is Gothic! 🧛‍♂️

We are a group of runners who meet most weeks for a run around the beautiful Vltava River's edge. You can bring your running shoes straight from the office/home office if you don't have time to stop at home. There will be a place to put your bags in the Cafe. We will run about 9 km along the river and have a drink afterwards. Paces vary! We will meet in the square near Kavarna Liberal (Hermanova 6), near the Vltavska metro/tram stop at 6:30 on Wednesday. See you there!

This time we are going to experience the world-famous spa town of Karlovy Vary, a spa town situated in western Bohemia. We will admire the grand 19th-century spa architecture, stroll along the impressive colonnades, and sip the presumably health-restoring sulphurous waters from 12 different springs in spouted ceramic drinking cups. One of the most famous attractions is the hot spring that spews out hot thermal waters to a height of 12 meters. Distance : 10 km (about 5 hours) Difficulty Rating : Easy Tour Highlights: • Professional and friendly guide • Transportation by air-conditioned bus • Visit the Mill & Market Colonnade • Entrance to the Church of St. Mary Magdalene • Visit and tour the Vrídelní Kolonáda underground spa’s inner workings) • Entrance to the Diana tower lookout • Entrance to St. Peter and Paul Cathedral • Visit the Japanese Garden • Moser glassworks tour OPTIONAL • Entrance to Jan Becher Museum (includes tasting of 4 different types of Becherovka) • Thun Porcelain Shop More information at : https://www.facebook.com/events/1425899982330883/

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.

Ke kódu se vrátila až mnohem později přes Czechitas a ReactGirls. Dnes pracuje v Mews jako junior software inženýr a v rámci ReactGirls podporuje další holky na jejich cestě do techu.

Vďaka nemu si aplikácie vymieňajú informácie cez API rýchlo a efektívne. Je jednou zo základných znalostí každého developera. Pozrieme sa na jeho štruktúru, základné pravidlá a princípy fungovania. **Natália Rydzá** pracuje jako Solution Developer ve firmě Jigx, která se zaměřuje na vývoj mobilních aplikací.

Ukážeme si konkrétní koučovací metody, jak využít své dosavadní zkušenosti, ujasnit si směr a proměnit své nápady v reálné příležitosti. Jana otevřeně nasdílí i svůj příběh - včetně výzev a pádů, které k růstu patří. Na závěr si představíme nadaci Gen for Future a představíme novou spolupráci s komunitou ReactGirls. **Jana Zahrádka Zajfrtová** je zakladatelka Gen for Future a průvodkyně žen na jejich profesní cestě. Ve své práci vytváří prostor, kde ženy objevují, že mohou - růst, měnit směr, realizovat vlastní projekty i ambice, které si dosud možná nedovolily naplno vyslovit. **Chceš přednášet na našem meetupu?** Vyplň nám přihlášku, kterou najdeš na našem webu ([ZDE](https://reactgirls.com/meetups)) a my se ti ozveme. Přednášku u nás můžeš mít na libovolné téma, týkající se vývoje. Vítáme ale i softovější témata. ℹ️ Na našich eventech pravidelně fotíme a natáčíme.

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/).

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 Communities - The Role of Religion/Spirituality. We will brainstorm together in an Open Space–style format, where participants choose topics themselves about what we want to discuss from this broad topic - questions to help you get inspired: What is the difference between spirituality and religion? Is religion the apex of community? How do we interact with the idea of spirituality and religion? 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 socialize 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

• What we'll do This meet up is for those who are learning English as a second language and want a chance to practice. We will provide a fun and interesting activity to encourage simple English conversation. It may be a game, an interesting topic, or whatever. We promise to keep the evening relaxed and give you a chance to practice your English. • What to bring Just you. • Important to know We are hosted by Do Slova Praha. As a church, we want to help our community in practical ways. We may hand out information to other events that our church does, but do not worry... this is not a religious event. Just come to practice English :) [https://www.doslovapraha.cz/](https://www.doslovapraha.cz/)

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
