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. Ve volném čase se učí dělat profesionální fotky a videa. **19:00 [Natália Rydzá](https://www.linkedin.com/in/nat%C3%A1lia-rydz%C3%A1/) (Jigx)** **JSON: Keď frontend a backend hovoria rovnakou rečou** JSON je spoločný jazyk webu, ktorý prenáša dáta čitateľne a nezávisle od programovacieho jazyka. 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. Kromě toho se ráda vrací jako kouč a mentor do komunit Czechitas a ReactGirls, kde sama s programováním začínala. Ve volném čase si najraději oddychne v sauně nebo cestováním. **19:30 [Jana Zahrádka Zajfrtová](https://www.linkedin.com/in/jana-zahradka-zajfrtova/) (Gen for Future)** **Jak začít realizovat své projekty** Co kdyby sis dovolila uvěřit, že můžeš? Že můžeš uspět v IT. Že můžeš realizovat svůj projekt. Že můžeš růst - i když si ještě nejsi jistá. 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. Fotky a videa používáme k propagaci našich aktivit na webu a sociálních sítích. Pokud na fotkách být nechceš, dej vědět organizátorům na místě. Těšíme se! Tým ReactGirls

**Beer, Pizza and IoT Meetup (DigiCert Special)** We would like to invite you to our next IoT Meetup at Concept Reply at the Reply offices in Munich. **Agenda** 19:00 – Securing the future Internet of Things with ML-KEM and ML-DSA (Talks by Kevin Hilscher and Daniel Stroehmann from DigiCert) 20:00 – Pizza & Networking **Description** Today’s Internet of Things (IoT) relies on a variety of protocols and communications technologies…CoAP, LwM2M, LoRaWAN, NB-IoT, Wi-Fi, Thread … many of which are not quantum-safe. While large-scale quantum computers capable of breaking current encryption aren’t yet available, the concept of “harvest now, decrypt later” is a significant concern. Now that NIST has released final versions of its first three Post-Quantum Cryptography (PQC) standards the race is on to make IoT quantum-safe. **We will explore** * What it takes to make an IoT solution quantum-safe. * The algorithms regulators, such as BSI, are recommending. * How to implement and transmit data between a device and an MQTT broker with TLS 1.3, ML-KEM, and ML-DSA using open-source tools. Please feel free to forward this invite to anybody who might like to take part. PLEASE NOTE: This Meetup will get streamed and recorded so you may get filmed by taking part. Doors open at 7PM for this one due to an event before. This event is exclusively for those with a professional background. Due to limited capacity, we reserve the right to restrict admission. Pizza, beer and seats first come first serve! :)

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. A table will be booked on name Michaela. Looking forward to seeing you! 😊

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.

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

Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. 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.

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.
